Electronic pneumatic separating and closing executing mechanism

Abstract

The invention discloses an electronic pneumatic separating and closing executing mechanism. The electronic pneumatic separating and closing executing mechanism is provided with a gas inlet (1), a separating solenoid valve (2), a closing solenoid valve (3), a travel sensor assembly (4), a pneumatic piston (5), a first gas cavity (61) and a second gas cavity (62). When the separating solenoid valve(2) is electrified and the closing solenoid valve (3) is not electrified, high-pressure gas enters the first gas cavity (61) from the interior of the separating solenoid valve (2) via the gas inlet (1), so that the pneumatic piston (5) is pushed to move towards one side, and a clutch is separated; and when the separating solenoid valve (2) is not electrified and the closing solenoid valve (3) is electrified, the high-pressure gas enters the second gas cavity (62) from the first gas cavity (61) via the interior of the closing solenoid valve (3), so that the pneumatic piston (5) is pushed to move towards the other side, and the clutch is closed. The travel sensor assembly (4) records the confirmed clutch position and provides the confirmed clutch position to a transmission box control unit,and thus electronic pneumatic separating and closing are achieved.

Description

technical field [0001] The invention relates to an electronic pneumatic clutch actuator, in particular, it belongs to the electronic pneumatic clutch actuator in the field of automobile braking. Background technique [0002] With the development of the automobile industry, the clutch system gradually tends to be automated. The actuator of the automatic clutch is the core component. At present, there are mainly two types of actuators for automatic clutches: hydraulic and electric. However, the hydraulically driven automatic clutch system requires a hydraulic system such as a motor pump and an oil tank, and the system is complicated. The motor-driven clutch actuator uses a DC motor as a power source. Although the structure is simple, the transmission efficiency is low, resulting in a long response time. [0003] However, the present invention aims at the defects and deficiencies of the prior art, and provides a clutch actuator with reasonable design, simple structure and con...
