KAMAZ gearbox switching mechanism
The gear shift mechanism (Fig. a) is assembled in the top cover 2 of the gearbox housing and consists of three gear shift rods, gear shift forks 3, 5, 6, a locking mechanism, three rod position clamps,
The suspension is a set of guide devices and elastic elements connecting the wheels to the frame;
The car frame is stamped, riveted, consists of two channel-section spars, variable in length, connected by cross members
The power take-off with an oil pump is designed to take power from the gearbox and is attached to its crankcase on the right side
The parking brake control valve is used to control the spring energy accumulators of the parking and spare brake drive (Fig. 1, a - c)
The pressure limiting valve serves to reduce the air pressure in the brake chambers of the front axle during low-intensity braking, which improves stability and controllability (especially on slippery roads), as well as to quickly release air from the brake chambers when releasing the brakes
The oil pump (Fig. 1) is two-section, gear type, has a drive gear ratio of 1.075 from the crankshaft nose gear, attached to the lower plane of the crankcase
The piston serves to sense gas pressure and transmit it through the piston pin to the connecting rod and crank of the crankshaft
The fine fuel filter is designed to remove from it the smallest mechanical particles that were not retained in the coarse filter;
Main gear of KamAZ vehicle
The main gear serves to increase torque on the drive wheels and transmit it from the driveshaft to the axle shafts at a right angle.
The pressure regulator automatically maintains the pressure in the pneumatic brake drive system within the range of 620-750 kPa, protects the pneumatic system from exceeding the maximum pressure (1000-1350 kPa) and protects the pneumatic system from contamination.
The double safety valve (Fig. 1) is designed to divide the supply line into two autonomous circuits (auxiliary and parking brake) and automatically turn off the damaged circuit in order to maintain the required pressure in the healthy circuit.
Center differential of a KamAZ car
The center differential is mounted in housing 3, which is mounted on the main gear housing of the intermediate axle.
Gear divider for KamAZ vehicle
The gear divider is mechanical, accelerating, with a pneumatic gear shift drive and consists of a housing 14 cast integrally with the clutch housing, a primary shaft 1 and an intermediate shaft 15, one pair of gears, a synchronizer 8 and a gear shift mechanism.
The engine consists of a crank and gas distribution mechanisms, as well as cooling, lubrication, power and control systems, and starting
In the article, we will consider possible malfunctions of the car's brake system and troubleshooting methods
KamAZ car driveline
The cardan transmission is used to transmit torque from the shaft of the gearbox or transfer case to the shaft of the vehicle's drive axle at changing angles and distances between them.
Mechanism for raising and lowering the platform of KamAZ-5511 and KamAZ-55102 dump trucks
Additional equipment of dump trucks includes a mechanism for raising and lowering the platform, which ensures the raising and lowering of the platform;
The low pressure fuel pump is installed on the high pressure fuel pump (on the rear cover of the speed controller) and is designed to supply fuel from the tank through the coarse and fine filters to the high pressure pump
Pre-heater PZD-30 for KamAZ
The electrical equipment of the preheater is designed to perform the following functions: induction coil 2 (figure) with a transistor switch generates high voltage current
