The front and rear suspensions of the bus (Fig. 1 and Fig. 2) consist of longitudinal semi-elliptical springs and hydraulic shock absorbers

The steering (Fig. 1) consists of a steering wheel, a steering column with a casing, a universal joint, a steering mechanism, a power hydraulic cylinder, a power steering pump, pipelines with hoses, longitudinal and transverse steering rods

Checking the condition of brake drums, pads and friction linings of wheel brake mechanisms is carried out at each maintenance-2

The pneumatic system of bus brakes consists of a compressor, pneumatic devices and pipelines

The diagram of the pneumatic drive of the brake system is shown in Figure 1.

An alternating current generator with a built-in semiconductor rectifier and an integrated voltage regulator is the main source of electrical energy

Exterior lighting devices include: headlights, front, rear and side marker lights, license plate lights, ground light (door step), rear fog lights, rear reflectors

The bus body is a load-bearing all-metal welded structure, which consists of six pre-assembled units: base, left and right sidewalls, front part, rear part and roof

Anti-lock braking system (ABS) is designed to prevent wheel locking during braking. ABS includes:

The table shows the probable causes of brake system failure, as well as methods for eliminating failures

Heating of the bus interior and the driver’s workplace is carried out by a liquid heating system that uses the heat of the engine cooling system and a liquid heater

The table shows the types of bearings, their catalog numbers and installation location in the car
