Abstract
The utility model relates to an automobile clutch booster assembly which comprises a cylinder assembly and a valve body assembly, wherein the cylinder assembly comprises a cylinder, a piston, a piston rod and an air cavity, and the valve body assembly comprises a valve body and an oil cavity, and a shift valve assembly is arranged on the valve body assembly; and the shift valve assembly comprises a shift valve body, a pull rod, a plastic guide sleeve an air inlet valve assembly, a moving valve assembly and a lock spring, the pull rod penetrates through the cylinder and is connected on the cylinder piston, and the lock spring is sheathed on the pull rod and is located in a position on the moving valve assembly. By arranging the shift valve on a clutch booster, shifting can be performed after a clutch is separated, smooth and synchronous shifting is ensured, and a synchronizer is protected.
Description
Technical field
The utility model relates to a kind of auto parts machinery, especially relates to a kind of clutch booster.
Background technique
At present; Employed clutch booster in the clutch operating system of domestic heavy-duty car, motor bus and engineering machinery; Though solved the heavy problem (gas power-assisted) of stepping on clutch pedal, in use also there are some defectives in such clutch booster.Like power assisted gearshift and the separately control of clutch separation power-assisted, can not guarantee to separate and shift gears and carry out synchronously, get gas power-assisted etc. in the time of can not guaranteeing to shift gears after the separation, brought very big inconvenience to the user.
The model utility content
The purpose of the utility model solves existing clutch booster exactly and structurally has the problems referred to above; Adopt clutch booster assembly and shift valve always to be integral design; Gearshift can be carried out after clutch separation, guaranteed that the steady of gearshift with synchronously, improves travelling comfort.
The technological scheme that technical problem adopted that the utility model solves is:
A kind of automobile clutch booster assembly comprises cylinder assembly and valve body assembly, and cylinder assembly comprises cylinder, piston, piston rod and air cavity, and said valve body assembly comprises valve body and oil pocket, it is characterized in that valve body assembly is provided with the shift valve assembly.
During practical implementation; Above-mentioned shift valve assembly has comprised gearshift valve body, pull bar, plastics guide sleeve, air intake valve assembly, mobile valve assembly and locking spring; Said pull bar passes cylinder and is connected on the cylinder piston, and said locking spring is sheathed on said pull bar and is positioned on the said mobile valve assembly position.Cylinder piston moves, and drives pull bar and moves, and utilizes the package power of locking spring, and pull bar drives the Kai Heguan of mobile valve, when mobile valve is run into step, drives locking spring and obtains deciding journey together from line slip from resetting control.Pull bar drives mobile valve, and the intake and exhaust of control shift valve are played power-assisted and decide journey and shift gears and get the effect of gas power-assisted.
The beneficial effect of the utility model is: the utility model is arranged on the clutch booster through shift valve, and gearshift can be carried out after clutch separation, has guaranteed the steady and synchronous of gearshift, has protected synchronizer.
