Abstract

The invention relates to the technical field of oil cylinder assistance, particularly to a power-assisted oil cylinder detection device of an automobile brake system. The detection device comprises a rectangular frame, a positioning mechanism and a fatigue test mechanism, wherein the positioning mechanism comprises a positioning table and a positioning air cylinder, the positioning table is provided with two mutually parallel positioning plates, the two positioning plates are both provided with coaxial positioning holes, and the fatigue test mechanism comprises a pedal pressing assembly rotationally installed at the top of the rectangular frame, a buffer assembly assisting a push rod in pushing and pulling, and a push-pull air cylinder. According to the invention, the pedal pressing assembly, the buffer assembly and the push-pull air cylinder of the fatigue test mechanism are matched with the oil pump in multiple driving modes, so that fatigue testing can be conducted on power-assisted oil cylinders of multiple structures, the service life and the sealing performance can be detected, the power-assisted oil cylinders can be rapidly positioned and detected through the positioning mechanism, and the batch detection efficiency of the power-assisted oil cylinders is improved.

Description

technical field [0001] The invention relates to the technical field of cylinder boosting, in particular to a detection device for a boosting cylinder of an automobile braking system. Background technique [0002] At present, large-scale mechanical vehicles are mostly equipped with a clutch booster system, which assists the clutch operation through the booster cylinder, so that the clutch operation is labor-saving and easy to operate. However, most of the current clutch booster cylinders are booster cylinders to push the piston out to assist, and the structure is complex, which is not easy to arrange and install. [0003] Patent No. CN202010013438.9 discloses a booster cylinder and its clutch booster system, which includes a housing and a piston inside the housing. The housing is provided with an oil inlet and an oil outlet that communicate with the inside of the housing. The outer end of the piston is connected with a pulling connecting rod for pulling power assistance. The...
