Abstract

The invention discloses a clutch auxiliary control device of an oil-electric hybrid electricity vehicle. The clutch auxiliary control device comprises a directional machine booster pump, a clutch booster and a valve block assembly; the directional machine booster pump supplies hydraulic pressure to the clutch booster; the clutch booster drives a clutch to be separated and reunited; the clutch is used for controlling the transmission connection states of an engine and a motor of the oil-electric hybrid electricity vehicle; the valve block assembly comprises a first two-position three-way valve, and is in pipeline connection with the vehicle directional machine booster pump, a vehicle directional machine and the clutch booster to form two hydraulic flow paths which enable the directional machine booster pump to communicate with the directional machine and enable the directional machine booster pump to communicate with the clutch booster correspondingly; and through formation of the two hydraulic flow paths, hydraulic oil in the directional machine booster pump can be conveyed to the clutch booster, and provides a power source for the clutch to be separated and reunited to the clutch booster in the hydraulic transmission force mode when the air pressure in an air storage tank is not enough.

Description

Technical field [0001] The invention relates to the technical field of vehicle clutch booster structures, in particular to a clutch auxiliary control device for a hybrid electric vehicle. Background technique [0002] In the prior art, the engine and the driving motor of many hybrid electric vehicles are connected by a clutch, and the driving motor has no neutral gear. The coupling and disengagement of the clutch is by the on and off of the air source of the vehicle by means of a solenoid valve to push the push rod on the clutch booster When the car is started, the drive motor starts separately. At this time, the clutch needs to be in a disengaged state. When the airtightness of the entire vehicle is insufficient, long-term parking will cause insufficient air supply for the entire vehicle due to air leakage. When the air pressure of the source is insufficient to meet the requirements for the use of the clutch booster, the engine and the drive motor cannot be separated and the car...
