Vehicle Clutch Pneumatic Automatic Manipulator

Abstract

The invention discloses a pneumatic automatic operating device for a vehicle clutch. The pneumatic automatic operating device comprises a pressure air source, wherein the pressure air source is respectively connected with pressure gas inlets of a plurality of three positions five ports center exhaust solenoid valves through an air transporting pipeline; an A working port of each three positions five ports center exhaust solenoid valve is connected with an inlet of a left pressure gas passage of each holding valve through the pipeline; a B working port of each three positions five ports center exhaust solenoid valve is connected with an inlet of a right pressure gas passage of each holding valve through the pipeline; an outlet of the left pressure gas passage and an outlet of the right pressure gas passage of each holding valve are respectively connected with a left working chamber and a right working chamber of an automatic precise return double-piston rod cylinder correspondingly; when power off, the right pressure gas passage and the left pressure gas passage of each holding valve are in the off state. The invention aims to provide the pneumatic operating device for the vehicle clutch, which has the advantages that the stationarity and flexibility of gear shift of the vehicle can be remarkably improved, the service life of a vehicle engine is prolonged, the failure rate is low, and the working performance is stable and reliable.

Description

technical field [0001] The invention relates to a pneumatic automatic control device for a vehicle clutch. Background technique [0002] Dry friction clutches are generally used on existing vehicles. The clutches are divided into separation state, slipping state, and combined state during operation. Among them, there are two states of slipping state, fully combined slipping and incompletely combined slipping , Incompletely combined sliding and grinding is also called semi-linkage state. The stability of vehicle starting and shift quality are closely related to the structure of the clutch operating device and the control strategy. Controlling the process of semi-linkage is the key to the smooth start of the vehicle. The requirement for the vehicle to start is fast and stable. For this reason, the driver is required to do "fast-slow-stop-slow-fast" when loosening the clutch pedal, the so-called "fast-slow-stop-slow-fast" The meaning is as follows: [0003] Fast: The free str...

Problems solved by technology

Due to the above-mentioned special requirements for controlling the clutch, it is difficult for many people, especially beginner drivers, to truly grasp the best operating rhythm of lifting the clutch pedal. Many people will not only cause violent speed changes and vibrations of the vehicle due to improper operating rhythm. , it will even cause the engine to stall when starting, resulting in a waste of energy and seriously affecting the comfort of the occupants in the car
