Wet clutch

Abstract

The invention relates to a wet clutch. A shaft (1) is mounted on a gearbox through a shaft bearing (2); a shaft cap (17) is arranged on the shaft (1); a joint cylinder (11) and a rear housing (12) are arranged on the shaft cap (17); bearings (13) are arranged between the rear housing (12) and the shaft cap (17); pistons (10) are arranged in the joint cylinder (11); return springs (9) are arranged between the piston (10) and the joint cylinder (11); a fuel return port (14), a joint hydraulic fluid port (15) and a cooling hydraulic fluid port (16) are formed in the shaft cap (17); the joint hydraulic fluid port (15) is communicated with the joint cylinder (11); driving friction plates (7) are arranged at the front part of the joint cylinder (11); driven friction plates (6) are arranged on splines of the shaft (1); a front housing (4) is arranged on the joint cylinder (11); a driving gear ring (8) is arranged between the front housing (4) and the joint cylinder (11); a front cover (3) and connecting gears (5) are arranged on the front housing (4). The friction plates are cooled with coolant oil, the service life of the clutch is prolonged effectively, the pressure is uniformly distributed, and the transmission torque is large.

Description

[0001] technical field [0002] The invention relates to a clutch, in particular to a wet clutch for heavy vehicles. Background technique [0003] The clutch is a component directly connected with the engine in the car transmission system. It is responsible for the cut-off and combination of the power and the transmission system, so it can ensure the smooth start of the car when starting, and also ensure the smoothness of the gear shift. It also prevents the transmission system from overload. At present, most of the clutches used on heavy vehicles are mechanical mechanisms with complex structures and short service life. Because of their quick bite response and strong bite force, the friction plates will generate high temperature, which often leads to clutch failure. Once a failure occurs, Flywheels, pressure plates, and clutch discs all need to be replaced. Heavy-duty vehicles need to be replaced every six months on average, and the replacement cost is relatively high. ...
