KAMAZ trailer brake control valve

The trailer brake control valve with a two-wire drive is designed to actuate the brake drive of a trailer (semi-trailer) when any of the separate drive circuits of the service brake system of the tractor are turned on, as well as when the spring energy accumulators of the drive of the spare and parking brake systems of the tractor are turned on.

The nozzle is used to spray fuel in accordance with the shape and volume of the combustion chamber

KAMAZ power steering pump

The power steering pump with an oil reservoir is installed in the camber of the cylinder block and is driven by the engine crankshaft

The starter is a sealed series-excited DC electric motor with an electromagnetic traction relay and a drive with a freewheel ratchet mechanism

The engine operates normally only under a certain thermal condition

Input shaft 13 is mounted on two ball bearings.

The front bearing of the input shaft with a cuff is located in the crankshaft socket, the rear bearing is located in the bore of the front end of the gearbox housing

To increase the liter power in the KamAZ-7403.10 engine, supercharging is used, i.e. air is supplied to the cylinders using a compressor under pressure 1.5-1.9 times higher than atmospheric

The brake chamber with a spring energy accumulator type 20/20 is designed to activate the brake mechanisms of the wheels of the rear truck of the vehicle when the service, spare and parking brake systems are engaged.

KAMAZ gearbox - maintenance

Maintenance of gearboxes includes periodic checking of their tightness; tightening the fastening of the support support to the ten-speed gearbox and the car frame

The master cylinder is mounted on the clutch pedal bracket.

In the housing 3 of the main cylinder there are cylindrical “A” and compensation “C” cavities in which the working fluid is located.

Design and operation of Kamaz auxiliary brake devices

The auxiliary brake (sometimes called the engine retarder brake) serves to reduce the load and temperature of the service brake brake mechanisms.

The towbar is designed for towing trailers, double-acting, and allows you to soften axial shocks that occur during movement in both directions

The fuel injection advance clutch is used to ensure economical engine operation at various speeds
