Description
Technical field
The utility model relates to a kind of auto parts and components, especially a kind of oil gas double purpose arrester.
Background technique
The general employing of present arrester is pneumatic.Be provided with push rod in the housing of arrester, its rear end is connected with the push rod dish, and is butted on the epithelium that is fixed in the housing bonnet by this push rod dish; Form pressurizing chamber between epithelium and bonnet, have the compressed air inlet of pressurizing chamber on the bonnet.During braking, promote push rod with input pressurized air and brake.Though the gas braking is reliable rapidly, and car was stopped in the shortest time, the mean lifetime of Pneumatic component is shorter than hydraulic braking, so its working life is short, the rate of fault height.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provide a kind of can be pneumatic again can hydraulic braking oil gas double purpose arrester.
The utility model solves the technological scheme that its technical problem adopts: this oil gas double purpose arrester, comprise the housing of forming by protecgulum, bonnet, be provided with first push rod in the housing, this first push rod front end stretches out outside the protecgulum, its rear end is connected with the first push rod dish, and is butted on the epithelium that is fixed in bonnet by this first push rod dish; Be arranged with first spring on first push rod, this first spring, one end is butted on protecgulum, and the other end is butted on the first push rod dish; Form pressurizing chamber in the epithelium, have the compressed air inlet that communicates with pressurizing chamber on the bonnet, have cavity in first push rod, be provided with second push rod in the cavity, this second push rod front end stretches out outside first push rod, and is connected with the clevis that is connected with break, and its rear end is connected with the second push rod dish; Be arranged with second spring on second push rod, this first spring, one end is butted on the first push rod front end, and the other end is butted on the second push rod dish, has the brake fluid import that communicates with cavity on first push rod.
The effect that the utility model is useful is: both be applicable to hydraulic braking, be applicable to the gas braking again.The characteristics that both had the hydraulic braking long service life have gas again and brake rapid reliable characteristics.

Description of reference numerals: clevis 1, the first push rod 2, cavity 2-1, brake fluid import 3, fastening piece 4, spring collar 5, the first Returnning springs 6, protecgulum 7, import epithelium 8, the first push rod dishes 9, screw 10, bonnet 11, compressed air inlet 12, bolt 13, clip 14, the second push rod dishes 15, second spring, 16, the second push rods 17, clamping bolt 18.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
This oil gas double purpose arrester, comprise the housing of forming by protecgulum 7, bonnet 11, protecgulum 7, bonnet 11 joints are by clip 14 bandings, be provided with first push rod 2 in the housing, these first push rod, 2 front ends stretch out outside the protecgulum 7, its rear end is connected with the first push rod dish 9, and is butted on the epithelium 8 that is fixed in bonnet 11 by this first push rod dish 9; The first push rod dish 9 is fixed in first push rod, 2 rear ends by screw 10.Be arranged with first spring 6 on first push rod 2, these first spring, 6 one ends are butted on protecgulum 7, and the other end is butted on the first push rod dish 9; Being with spring collar 5, the first springs 6 on first push rod 2 is placed on the boss of spring collar 5 and locatees.Form pressurizing chamber in the epithelium 8, have the compressed air inlet 12 that communicates with pressurizing chamber on the bonnet 11, has cavity 2-1 in described first push rod 2, be provided with second push rod 17 in the cavity 2-1, these second push rod, 17 front ends stretch out outside first push rod 2, and being connected with the clevis 1 that is connected with break, its rear end is connected with the second push rod dish 15; Be arranged with second spring 16 on second push rod 17, these first spring, 16 1 ends are butted on first push rod, 2 front ends, and the other end is butted on the second push rod dish, 15, the first push rods 2 and has the brake fluid import 3 that communicates with cavity 2-1.This arrester is fixed on the automobile support by fastening piece 4.Clip 14 is by clamping bolt 18 lockings.Bonnet 11 has two compressed air inlet 12, and the bolt 13 that one of them compressed air inlet 12 is threaded and is useful on the shutoff opening gives over to standby.
This brake chamber is taken into account the characteristics of gas braking, hydraulic braking simultaneously, and the advantage of two kinds of brakings is given full play to.During automobile was advanced, during the foresight brake, light brake-apply was enabled hydraulic braking, brake compensation is comfortable, during Emergency braking, depresses brake petal fast, then hydraulic pressure, air-pressure brake start simultaneously, utilize the rapid reliable characteristics of gas braking braking, and car was stopped in the shortest time.Foresight brake frequency is than the Emergency braking height, thereby the braking of purer gas, and pressurized air is taken will lack many, can select for use compressor displacement, gas storing pipe volume less relatively, both saved the space, save the energy again.The mean lifetime of Pneumatic braking device easily damaged parts is short than hydraulic braking, after giving hydraulic brake system with major part braking task, certainly will the life-span of Pneumatic braking device will be prolonged greatly, for hydraulic braking, because after the maximum emergency braking of power consumption shared by the gas braking, its working load was alleviated significantly, thereby prolonged operating life, thereby, this arrester functional reliability and life-span, obviously all be better than traditional pure gas braking or pure hydraulic braking.
