Clutch manipulation cylinder of engineering mechanical braking system

Abstract

The invention discloses a clutch manipulation cylinder of an engineering mechanical braking system. The clutch manipulation cylinder is provided with a hydraulic cylinder which comprises a hydraulic cylinder body, a hydraulic piston assembly, an oil inlet connector and a hydraulic cylinder oil outlet; the clutch manipulation cylinder is also provided with air cylinders, wherein each air cylinder comprises an air cylinder body assembly, an air cylinder push rod, an air inlet, an air cylinder piston assembly and a spring holder assembly; the air cylinders are connected coaxially through an air cylinder oil cylinder connection bolt and an air cylinder oil cylinder connection nut; and each spring holder assembly and each hydraulic piston assembly are in contact axially. By adopting the technical scheme, under the condition that a pedal mechanism is not used or the pedal mechanism has a fault, a booster air inlet valve of the clutch is opened through inputting working air pressure to the air inlet, and the separation of the clutch manipulation mechanism also can be realized so as to reach the braking effect; and the braking process is simple to operate, performances are stable, friction plates can be separated by the air pressure braking in a short time, and also can return to the original position in a short time, the braking efficiency is high, thus the service life of the product is prolonged greatly.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and relates to the braking element technology of an engineering machinery braking system. More specifically, the present invention relates to a clutch operating cylinder of an engineering machinery braking system. Background technique [0002] At present, the clutch control mechanisms used in most construction machinery road rollers in China use pedal-type mechanisms, mainly by stepping on the pedal mechanism to control the clutch master cylinder, and the clutch master cylinder outputs oil pressure to open the intake valve of the clutch booster, thereby Realize the disengagement of the clutch mechanism. [0003] This braking method has very high requirements on the sensitivity of each braking component, especially the clutch master cylinder. If the pedal mechanism is insensitive or fails, the clutch mechanism cannot be separated, the friction plates will burn out, and the entire br...

Problems solved by technology

[0003] This braking method has very high requirements on the sensitivity of each braking component, especially the clutch master cylinder. If the pedal mechanism is insensitive or fails, the clutch mechanism cannot be separated, the friction plates will be burned, and the entire braking process will fail. cause a serious accident

[0004] figure 1 It is a mechanical brake clutch master cylinder commonly used in the prior art. Step on the pedal mechanism to push the hydraulic piston to move to the right to realize the separation of the clutch mechanism. The product has a single working principle
