Abstract
A booster pump for an automobile clutch is composed of a push rod (1), a dust shield (2), an air cylinder (6), a big piston (7), a spring (8), a leather cup (9), a piston rod (10), a valve plate (11), a small piston (12) and the other components. The utility model is characterized in that: semi-sealing protected type filtering structure is adopted by the utility model; no air inlet and outlet are arranged on the dust shield (2); at least two clutch booster pump cover plates are arranged, and each plate is equipped with two small holes; and a filtering ring (3) is clipped between the cover plates. The booster pump for an automobile clutch of the utility model has the advantages that: the inlet air is clean; the air intake and exhaust are smooth; the air inlet and outlet are not easily been blocked; the cavity of the dust shield is free from high pressure air and is not easily broken; the operating condition of the big piston is good and the motion is flexible; the separation of the clutch is thorough; the operation is reliable and the overall service life is prolonged for 2 two 3 times; the processing and assembly efficiency is high; the maintenance and upkeep of the user are convenient and the other performances.
Description
Technical field
The utility model belongs to the technical field of auto parts and components automobile clutch boost pump, particularly a kind of automobile clutch boost pump of novel inlet and outlet structure.
Background technique
At present, the automobile boost pump generally adopts diaphragm type boost pump or two kinds of structures of plunger type boost pump.
The present domestic following two kinds of inlet and outlet mode of structure that have of plunger type boost pump:
1, the inlet and outlet hole is generally 4 φ 1.5 holes on dust-proof cover.There are two aspect shortcomings in this clutch power-assisted pump inlet and outlet structure: because this port communicates with atmosphere, dust-proof cover will suck dust, no dustproof effect (being commonly called as vacuum cleaner) by these holes on the one hand.4 φ 1.5 hole gross areas are equivalent to a φ 3 hole sectional areas on the other hand, the diameter of boost pump master working cylinder is generally: φ 90, φ 102, the about 33mm--38mm of the working stroke of piston, the gas of so big volume is quite difficult by 4 φ 1.5 aperture emptyings in moment.Under the promotion of 5--7KN power, telescopic bellows certainly leads to one as the inflation process that blows up a balloon when elongating, can cause the often outside modification in the low ripple place of dust-proof cover like this, the convex-concave ripple is all heaved into olive-shaped, back and forth cracks, ruptures behind the several times.Cause in the boost pump master cylinder to suck a large amount of silt particles, quicken Sealing premature wear on the big piston, come off, leak gas, cause that ouput force descends, clutch separation not thoroughly (engage a gear difficulty, Strike note is arranged), burning friction plate ...This kind inlet and outlet structure boost pump causes the boost pump ten thousand kilometers early failues of 1-2 of travelling because of sucking dust.
2, the inlet and outlet hole is on the thick aluminum alloy material cylinder of about 8mm cover plate.This kind inlet and outlet structure plunger type boost pump, inlet and outlet hole easily stop up, easy cleaning not.Manufacturing efficiency is low, the cost height.
Summary of the invention
The purpose of this utility model is the defective of finding in actual applications at the said structure form, has done bigger improvement at aspects such as boost pump master cylinder inlet and outlet passage and increase dust preventions, and a kind of novel automobile clutch boost pump is provided.
The technical solution of the utility model is achieved in that
The automobile clutch boost pump, comprise compositions such as push rod, dust-proof cover, cylinder, big piston, spring, leather cup, piston rod, valve block, small piston, it is characterized in that not having port on the dust-proof cover, clutch power-assisted pump closure has two at least, the port that staggers mutually more than two is arranged on each cover plate, accompany sphere filter between cover plate.
The utility model automobile clutch boost pump has the air inlet cleaning; Inlet and outlet are unobstructed; Be difficult for stopping up port; The dust-proof cover inner chamber does not bear pressurized gas, not easy-rupturing; The big piston operating mode is good, movement sensitive, and clutch separation is thorough; Reliable operation, raising assembly life-span prolong 2-3 doubly; Processing, efficiency of assembling height, advantages such as user's maintenance, easy maintenance.
