Integral type clutch booster with fixed-range gas taking

Abstract

The invention discloses an integral type clutch booster with fixed-range gas taking. The integral type clutch booster comprises a cylinder component, a valve seat and an automatic-measurement (alarming) part assembly for the wearing capacity of a friction plate, wherein the cylinder component comprises a cylinder body, a pulling rod, a pulling rod disc, a piston and a piston rod; the lower end of the pulling rod is connected with a movable valve seat, and the upper end of the pulling rod is movably connected with the pulling rod disc; the pulling rod disc is connected with the piston at the upper end; the valve seat is internally provided with a gas taking valve and the movable valve seat; a gear-shifting valve body and the valve seat are designed into a whole body; the movable valve seat is arranged at the lower end of the gas taking valve; the automatic-measurement (alarming) part assembly for the wearing capacity of the friction plate comprises a measuring disc and a measuring rod. The integral type clutch booster disclosed by the invention has the advantages that the gear-shifting valve body and the valve seat are designed into the whole body, so that the problem of damage before use is avoided; automatic measurement and alarming can be carried out when the wearing capacity of the friction plate of a clutch reaches the specified requirement.

Description

technical field [0001] The invention relates to a clutch booster used in a clutch control system of a large passenger car, a heavy-duty vehicle and a construction machine, in particular to an integral fixed-range air-taking clutch booster. Background technique [0002] At present, the clutch booster used in the clutch control system of domestic buses, heavy-duty vehicles and construction machinery has already used a clutch booster with fixed-range air intake and wear alarm (patent number: 200820162357.X), but due to changing The stopper valve and the valve seat are usually connected by bolts, two independent parts, not a whole, which often makes the shift valve (including the moving valve seat, air intake valve, etc.) The valve part is often "damaged before use", which has plagued the normal use of the vehicle for a long time. Contents of the invention [0003] In view of the above problems, the present invention proposes that the shift valve body and the valve seat ar...
