Modern design, compliance with the requirements of environmental safety and passenger comfort, simplicity and ease of operation are successfully combined with effective performance, which makes this model a leader in the Russian market in its class.

School version: in accordance with GOST R 51160-98 “Buses for transporting children. Technical requirements".

History of creation

Initially, the PAZ-3204 index was assigned to the all-wheel drive version of the PAZ-3203 series buses (PAZ-3205 prototypes). In 1973, a single prototype was produced, which successfully passed state tests and was recommended for mass production, but it suffered the same fate as the entire PAZ-3204 series (1973 model).

In March 2009, 2006 model was modernized The design of the bus was somewhat simplified. From then on, it began to be designated PAZ-320402-03, the air suspension gave way to a spring one, the bus underwent a facelift - it received new headlights and windows with rubber seals instead of the modern glued ones. In addition, the front passenger door was moved closer to the front axle of the bus, and the floor level was raised. The bus began to be produced with several interior layout options:

• city ​​(17 seats, total capacity - 53 people);
• urban and suburban (21 seats, total capacity - 50 people);
• suburban (25 seats, total capacity - 43 people).

The standards of the bus industry are getting higher every year. March 2009 was significant for the PAZ company. After all, it was then that the PAZ 3204 bus was modernized in all its glory. Moreover, the bus received the title of legend in urban and suburban transportation.

Design

The new developed transport replaced the 3205 model. In general, the first PAZ 3204 bus was released in 2006. However, the production of a small series started only in 2007.

Compared to model 3205, this device has been changed for the better, as the design features have been simplified. For example, the spring suspension was replaced with pneumatic due to incorrect operation.

It is also worth noting that visual changes have affected the design of the headlights and the window installation system. Now the glass is not glued in, but installed with rubber seals. In addition, the bus began to be produced with a high floor level, and also with a front door moved closer to the front axle.

In other matters, the changed technical characteristics helped create a classic bus with basic equipment. Now the design satisfies the needs of both drivers and passengers.

The PAZ 320402 model is produced in 3 main configurations:

• City with a capacity of 53 people in 17 seats;
• Urban and suburban with 21 seats and a total capacity of 50 passengers;
• The suburban one has 25 seats with a total capacity of 43 passengers.

Heating and ventilation system

Natural ventilation of the cabin occurs through the ceiling hatches and side flaps. The most interesting thing is that there is even an air conditioner installed here.

If we consider the heating system, then the car has 4 heaters. Plus 1 in the driver's cabin. Moreover, heaters take heat from the engine. Thus, they contribute to additional cooling of the engine.

Other Features

The total weight of the PAZ 320402 depends on the model configuration; it varies from 5055 to 8825 kg. The load on the front axle is 2580 kg, and on the rear axle – 6245.

It should be added that the bus can travel at a maximum speed of 95 km/h.

Current modifications

Based on the PAZ 320402 modification, only 9 models were produced. They are actively used throughout Russia:

• PAZ 3204 with index 01 01 and 01 03;
• Model with a Cummins engine called PAZ 3204 02 03;
• PAZ 3204 02 04 with YaMZ-534 engine;
• Model with serial number 02 05 and 02 07;
• A modification of the gas cylinder type with a ZMZ engine called PAZ 3204 02 08;
• Example 3204 03 01 features a Tata wheelbase with screen doors;
• Bus PAZ 3204 12 03 extended type with a Cummins engine of 185 hp;
• Combined bus with index 12 10. This is an amazing combination of an extended gas cylinder type with a Cummins ISB 5.9 G195 engine. Interestingly, there is a model on the market with the number 12 05.

Two models have also been developed for transporting children. Since school transport meets the requirements of GOST R 51160-98, it can be proudly called as safe and comfortable as possible. By the way, these are the models:

• School PAZ 320470 03 with Cummins 4ISBe 185-B engine;
• PAZ 320470 05 for schoolchildren is distinguished by a Cummins ISF3.8s3168 engine.

Engine

Depending on the configuration of the bus, Cummins or YaMZ 534 engines can be installed. In general, the power unit is adapted to the conditions of domestic roads. Moreover, the service interval is 15,000 km.

The diesel tank capacity is 105 liters. Fuel consumption per 100 km at a speed of 60 km/h is 19 liters. At a bus speed of 80 km/h, the consumption will be 22 liters.

Steering system

To control the car during the trip, a Csepel-Airvita 300.92 steering gear with hydraulic booster is used. The basic configuration uses a 5-speed manual transmission S5-42. And in more expensive models, a 6-speed Allison T2100 automatic transmission is installed.

Groove 320402: technical specifications

In the first series of the bus, the suspension was pneumatic. But due to its low reliability, starting in 2009, it was replaced with a dependent leaf spring equipped with telescopic shock absorbers, and the rear suspension was strengthened with additional corrective springs.

All PAZ 3204 are equipped with ABS, and each of the two circuits of the brake system can be used as a spare one. The parking brake acts on the rear axle and is also pneumatically actuated.

The brake system of the bus meets the latest requirements for the safety of passenger transportation.

The technical characteristics of the bus differ in the layout of the cabin and the number of passenger seats, engine models (Yaroslavl 150 hp or German Cummin 168 and 183 hp are used), gearbox and axles. All engine models installed on buses comply with Euro 3 or 4 standards. Most buses have manual 5-speed gearboxes, but some modifications are equipped with an automatic transmission.

Bus PAZ-3237: technical characteristics, features and reviews:

Since the beginning of the 2000s, the first low-floor buses began to appear in Russia. But they were all large and were used only in megacities. The Pavlovsk plant was the first to produce a production model of a low-floor, low-capacity bus. This model can be used in small cities with low passenger traffic. So, meet PAZ-3237. Technical characteristics will be discussed in the article.

Design

Externally, the PAZ differs significantly from its counterparts built on the platform of the 53rd “Lawn”. This is a completely new modern bus with a large glass area and low ground clearance. The car features wide glass doors. The side windows are lightly tinted. The design of the PAZ-3237 bus is not much different from its large low-floor counterparts. This is not surprising, because the platform is unified with buses from Liaz (Likinsky Plant).

There is the same body design and primitive headlight shape. By the way, on the roof there is an LED display with the route number and other necessary data. The Pavlovsk plant provides an 8-year guarantee for protection against through body corrosion. The metal is galvanized and in the absence of mechanical damage will be used for a very long time. By the way, the body on the low-floor groove of the 3237th model is load-bearing. Usually Pavlovsk buses were built on a frame.

It was its absence that made it possible to reduce the floor position and increase the volume of interior space.

Dimensions

The PAZ has standard dimensions for a city bus. The length of the body is 7.88 m, width – 2.5 m, height – 2.82 m. The wheelbase is 3.65 m. The car has a small turning radius – only 8 and a half meters. The load capacity of the PAZ-3237 bus is 4 tons with a total weight of 10 tons. The previously produced PAZ-3205 had similar characteristics.

What is inside?

The cabin is designed for 54 passengers, with a total of 16 seats. Ventilation is provided through a mechanical hatch and side vents. Thanks to the light tint, the interior does not get too hot on a sunny day. PAZ-3237 is equipped with plastic anti-vandal seats with leatherette covering. Additionally, the backrest has handles for standing passengers. Entering the salon is very simple and convenient.

Now you don’t have to climb up the stairs, clinging to the handrails. PAZ-3237 has a very spacious interior, that’s what passengers say. A heating system is implemented on the side walls. Warm air is produced from two heaters - standard and autonomous. Inside there are all the necessary handrails and lighting. Now let's move on to the driver's seat. It is separated from the salon by a metal partition.

The driver's workplace is organized in a simple way: a two-spoke steering wheel, a seat with minimal lateral support and an ascetic instrument panel with round dials. The car can be equipped with a radio – for this there is a separate block on the panel. The steering column is adjustable back and forth, which is very convenient, drivers say. They also talk about good visibility. Dead zones are kept to a minimum.

The mirrors are very large and informative.

Specifications

The American Cummins is provided as the power unit for the low-floor PAZ. This is a 4-cylinder diesel engine equipped with a simple turbine without an intercooler (radiator for air cooling). With a volume of 3920 cubic centimeters, it produces 150 horsepower. Drivers say that the American engine is very high-torque. Torque (550 Nm) is fully available from just one and a half thousand revolutions.

The power unit complies with Euro-2 environmental standards. The transmission can be a five-speed manual transmission or an Allison 5-mode automatic transmission. What performance characteristics does this bus have? PAZ-3237 consumes about 18 liters of fuel per 100 kilometers with manual transmission. On the machine, this figure increases to 20.

The maximum speed of the bus is 90 kilometers per hour.

Modification 3237-03

This modification differs from the main one in a different power unit. It contains a Cummins model 185B. This is a 4.5-liter diesel unit with in-line cylinders. The power of this engine is 183 horsepower. Torque – 636 Nm. It is available in the range from 1.2 to 1.7 thousand revolutions per minute.

THIS IS INTERESTING: How many seats are there on the bus?

Just like the previous unit, it does not have gas neutralization systems and complies with Euro-2 standards. It is equipped with a non-alternative automatic transmission from Ellison 2100 series with 6 speeds. Fuel consumption is 24 liters per 100 kilometers in the urban cycle.

The maximum speed is electronically limited to 90 kilometers per hour.

3237-05

This modification is equipped with Cummins ISF series. With a displacement of 3.8 liters, it produces 170 horsepower. The engine has a good torque reserve (592 Nm in the range of 1.3-1.7 thousand rpm) and low fuel consumption. The car spends up to 20 liters per hundred when paired with a six-speed Allison torque converter. Unlike all previous ones, the Cummins ISF complies with Euro 4 emissions standards.

3237-09

This bus is equipped with an American diesel engine of the ISBe series with a turbine. With a displacement of 4.46 liters, it produces 160 horsepower. This is less than ISF. But the torque (which is more important for such a vehicle) is 600 Nm. This unit meets Euro-4 standards and is equipped with the same automatic transmission.

Chassis

A carriage-type body is used as a load-bearing element on the PAZ. It is on it that the engine, gearbox, suspension and other components are mounted. A dependent circuit is implemented at the front. PAZ-3237 is equipped with air spring elements on the front axle and four telescopic shock absorbers.

Also, at the request of the customer, the suspension can be changed to completely independent. But this significantly affects the cost of the bus and, as a consequence, its payback period. At the rear, a dependent suspension with a continuous “Slave” axle and air springs is used. Additionally, a stabilizer bar is used here.

Steering – CSEPEL “screw-nut-rack” type. The PAZ-3237 is also equipped with a hydraulic booster.

Brake system

The bus uses a completely pneumatic brake system. At the front and rear there are ABS disc elements from the German manufacturer Knorr-Bremse. Previously, PAZs used archaic drums, which were used on the Soviet “Lawns”. The parking brake operates from spring energy accumulators. Two wheels on the rear axle are blocked. As drivers note, the Pavlovsk bus has very effective and responsive brakes.

Bus PAZ-3237: price, equipment

The cost of a new car starts from five million rubles. Also some models are available on the secondary market. A three-year-old low-floor PAZ-3237 can be purchased at a price of 2.5 million. The most expensive ones cost up to 3 million rubles.

You will not need to buy spare parts for the PAZ-3237 any time soon. After all, the bus comes with a factory warranty for a period of one and a half years or 100 thousand kilometers.

During this time, the dealer will replace any failed part free of charge (of course, if the operating rules have not been violated). The manufacturer allocates a service interval of 15 thousand kilometers.

As for the choice of additional options, the standard equipment can be expanded at the request of the customer. The list of options includes:

• Fog lights.
• A video surveillance system combining two cameras and a four-channel recorder.
• Informant with loudspeakers and side direction indicators.
• System of cashless fare payment and passenger counting in real time.
• Automatic fire extinguishing system.
• Supply and exhaust ventilation. It combines four reversible fans. Forced ventilation is designed to minimize the entry of dust into the cabin and prevent fogging of the windows in humid weather.

Conclusion

So, we found out what PAZ-3237 is. With the release of this model, the plant entered a new stage of development. Finally, high-quality and modern city buses have appeared in Russia.
