Problems solved by technology

[0004] 1) Short service life of the clutch
[0005] Since the currently used friction clutches transmit power by the friction of the main and driven friction plates, the wear of the main and driven friction plates is quite serious during the shifting process, resulting in shortened effective service life of the friction plates
[0006] 2) Large impact, high noise, reducing the life of parts
[0007] In the process of shifting, due to the large inertia of the vehicle, the speed difference between the main and driven friction plates is large, and the combination is rapid after the shift is completed, resulting in large noise and impact, so the service life of the drive train components will be greatly reduced
[0008] 3) Serious pollution
[0009] Since the friction plate contains toxic as

Embodiment 1

[0029] working principle:

[0030] The so-called electro-hydraulic integrated control clutch: it is to use the ring gear connected to the crankshaft of the engine to rotate together with the gear connected to the first shaft of the gearbox to form a pair of meshing gear pumps. A crescent block is added to the internal meshing gear pump to form an oil passage connecting the high and low pressure oil chambers of the gear pump. Electricity is used to control the opening and disconnection of the hydraulic oil circuit generated by the gear pump, and to control the inner ring gear and the oil passage. The relative rotation of the gears meshing with it realizes the transmission and interruption of power.

[0031] work process:

[0032] The up and down position of the cut-off valve 6 is controlled by the on and off of the electromagnet 10, which is used to control the on and off of the circuit between the high and low pressure oil chambers, that is, to realize the separation and comb...

Abstract

An electrohydraulic combination control type clutch belongs to automotive parts technology field. It features shell respectively fitting with interval of annular gear, gear and disconnecting valve, annular gear engagement transmission with gear, a crescent block fixed in shell, said crescent block having hydraulic fluid chamber having disconnecting valve to form high-pressure oil cavity A and low-pressure oil cavity B respectively on outer two ends of crescent block, disconnecting valve pivot joint with electromagnet fixed in shell. Said invention has advantages of 1, reliable product performance, long service life and low cost, 2, low noises, small impulsion, long spare service life, 3, no pollution, 4, simple installing, making and processing.

Description

technical field [0001] The invention belongs to the technical field of automobile parts. Background technique [0002] When the car starts and shifts, the engine output power is interrupted and transmitted through the separation and combination of friction plates between the active part (connected to the engine) and the driven part (connected to the transmission input shaft) of the clutch. [0003] At present, the clutches used in the automotive industry are all friction clutches. But there are many defects in this product, because product performance and structure reason, these defects can't be solved. Mainly manifested in the following aspects: [0004] 1) Short service life of the clutch [0005] Because the currently used friction clutch transmits power by the friction of the main and driven friction plates, during the gear shifting process, the main and driven friction plates wear very seriously, which shortens the effective service life of the friction plates. [0...
