Problems solved by technology

When the pure air pressure drive fails, the clutch slave pump adopts the hydraulic-pneumatic hybrid drive mode to realize the clutch action, so the clutch slave pump needs to be used in conjunction with the corresponding control oil circuit, the structure of the control oil circuit is relatively complicated, and the clutch oil is used to control other The operation of the equipment has a certain impact, and the use of hydraulic oil will cause certain pollution

Embodiment Construction

[0013] The embodiment of the hybrid vehicle clutch slave cylinder of the present invention: as Figure 1 ~ Figure 2 As shown, the hybrid vehicle clutch cylinder includes a booster cylinder 17, a booster cylinder piston 19 is arranged in the booster cylinder 17, and the booster cylinder piston 19 separates the booster cylinder 17 into a front cylinder and a rear cylinder. The piston 19 is fixedly connected with a piston rod 2 that can move back and forth with the piston 19 of the booster cylinder. The piston rod 2 is covered with a piston spring 18. The inner wall of the rear side is connected, and the front side of the booster cylinder piston 19 is provided with a clutch push rod 12. The clutch push rod 12 is coaxially arranged with the piston rod 2 and can move back and forth with the piston rod 2. The clutch push rod 12 and the booster cylinder piston 19 can be Slight rotation fit; also includes booster air inlet 3 and control air inlet 4, the booster air inlet 3 communicate...

Abstract

The invention relates to a clutch slave cylinder for a hybrid vehicle. The clutch slave cylinder comprises an assisting cylinder body, an assisting cylinder piston is arranged in the assisting cylinder body, a piston rod capable of performing reciprocating motion along with the assisting cylinder piston is arranged on one side of the assisting cylinder piston close to a main cylinder body, and one end of the assisting cylinder piston away from the piston rod is connected with a clutch push rod. The clutch slave cylinder further comprises an electromagnet device for outputting linear thrust, the electromagnet device is provided with an output end consistent with the movement direction of the assisting cylinder piston, and the output end of the electromagnet device is in transmission connection with the piston rod or the clutch push rod. The magnetic field thrust generated by the electromagnet device is adopted to push the piston rod or the clutch push rod to move, hydraulic oil in the prior art is replaced by means of current, so that the clutch slave cylinder is simple in structure and convenient to control, and pollution caused by the adoption of the hydraulic oil in the prior art is reduced.

Description

technical field [0001] The invention relates to a clutch cylinder, in particular to a clutch cylinder for a hybrid vehicle. Background technique [0002] At present, the structure of the clutch cylinder used in hybrid vehicles is as disclosed in the Chinese patent "a clutch cylinder for hybrid vehicles" whose application publication number is CN102562852A. The coaxial and fixed booster cylinder is equipped with a booster cylinder piston that divides the booster cylinder into two parts, the front chamber and the rear chamber. The side of the booster cylinder piston near the main cylinder is equipped with a The piston rod that the piston moves back and forth also includes the booster air path and the control air path that communicate with the rear chamber of the booster cylinder. There is a reversing valve that is directly connected up and down between the booster air path and the control air path. The upper end of the reversing valve is connected to the The boost air circuit...
