Off-vehicle clutch control device

Abstract

The invention discloses an off-vehicle clutch control device comprising an oil path switch valve, a gas path control valve and a control device oil pumping mechanism. The oil path switch valve and thegas path control valve communicate with the control device oil pumping mechanism. The control device oil pumping mechanism is connected with the oil storage tank. The oil path switch valve is provided with a master pump connector and a boosting cylinder connector and connected with a clutch master pump and a boosting cylinder. In the normal state, the boosting cylinder connector communicates withthe master pump connector and does not communicate with the control device oil pumping mechanism. The gas path control valve is provided with a gas source connector and an exhaust opening. In the normal state, the gas source connector does not communicate with the control device oil pumping mechanism. The off-vehicle clutch control device is connected with an existing hydraulic driving clutch control device in parallel. The off-vehicle clutch control device is simple in structure and high in practicability and achieves the purposes of reducing the number of operators and improving the operation convenience.

Description

technical field [0001] The invention relates to an off-vehicle control device for a clutch, which belongs to the technical field of auto parts manufacturing. Background technique [0002] When the on-board equipment in the special vehicle is working, the operator needs to control the working state of the clutch under the vehicle to realize the power pickup and gear switching of the on-board working equipment. In order to realize off-vehicle clutch control, the vehicle-mounted equipment needs to be equipped with an off-vehicle control device in parallel with the driving clutch control, which is used for clutch operation outside the cab when parking. The clutch control device under the car can provide more convenient operation, reduce the number of staff required, and reduce labor costs. At present, the common method of controlling the clutch under the car is the rocker arm flexible shaft mechanism. The flexible shaft is connected with the clutch pedal arm. Control the actio...

AI Technical Summary

Problems solved by technology

Regardless of whether the rocker arm flexible shaft mechanism or the pneumatic mechanism is used, both of them need to be provided with a connecting rod connected to the clutch pedal arm; while the vehicle is running, the connecting rod may interfere with the driving clutch control and affect the driver's control of the vehicle state; in addition , arrange the above-mentioned rocker arm flexible shaft mechanism and pneumatic separation mechanism in the cab to occupy limited space in the car, which cannot be realized in some models
