General description of the clutch (Mercedes-Benz Sprinter 903)

On vehicles with a manual transmission, the clutch separates the source of torque—the engine and the transmission. When starting to move, the clutch smoothly transfers torque from the engine to the transmission. The driven clutch disc has asbestos-free friction linings. The clutch diameter and the clamping force of the driven disk depend on the engine power.



Mercedes Sprinter Clutch (figure 175) consists of the following parts: clutch drive (clutch pedal, master cylinder, hose, slave cylinder, release fork, clutch release bearing) and clutch parts (pressure and driven disks, flywheel), located in the gearbox housing.

The clutch works as follows: when you press the clutch pedal, the hydraulic drive is activated, transmitting pressure to the slave cylinder and from it to the clutch release fork. A clutch release bearing is attached to it, which, acting on the ends of the diaphragm spring petals, "unloads" it, disengaging the clutch. The driven disk then begins to rotate freely between the flywheel and the pressure plate. When the clutch pedal is released, the spring again acts on the pressure plate, clamping the driven one - the clutch is engaged.
