Description
Technical field
This utility model relates to brake device field, especially a kind of durable type energy storage spring brake chamber.
Background technology
Connection fork on the push rod of existing storage brake room is for U-shaped, and connecting, fork has been directly connected to roller by bearing pin, in the course of the work, directly contact between roller with bearing pin, in roller progressive rolling movement process, easily the Innerside wear to bearing pin and roller, energy storage spring brake chamber fault, affect service life.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction to solve the deficiency of above-mentioned technology, can effectively reduce the abrasion between bearing pin and roller, improve the durable type energy storage spring brake chamber in service life.
In order to achieve the above object, durable type energy storage spring brake chamber designed by this utility model, it includes protecgulum, bonnet, epithelium, push rod and push rod dish, described protecgulum and bonnet are connected, described epithelium is arranged between protecgulum and bonnet, and the edge of epithelium is fixed on the junction of protecgulum and bonnet, epithelium forms two airtight chambers with protecgulum and bonnet respectively；The centre position of bonnet is provided with air inlet；Be provided with through hole in the center of protecgulum, described push rod is arranged in through hole and stretches into inside protecgulum；Being provided with push rod dish in the cavity that protecgulum and epithelium are formed, and push rod dish is fixed on the center of epithelium, described push rod is positioned at the end of protecgulum and is fixed on the center of push rod dish, and the push rod between protecgulum and push rod dish is arranged with return spring；Connection fork it is fixed with on the top of the push rod outside protecgulum, the described cross section connecting fork is U-shaped, is provided with corresponding two through hole, is provided with bearing pin in through hole on the sidewall connecting fork, bearing pin between the sidewall connecting fork is arranged with lining, is arranged with roller in sleeve outer surface；Described lining is high-tensile strength brass bushing.
Technique scheme, vehicle is in driving process, and when vehicle needs to brake, air inlet is inwardly inflated so that the air pressure in the cavity between epithelium and bonnet increases；The push rod dish on epithelium being promoted to move forward and compressed by return spring, it is achieved thereby that the moving forward of push rod, brake is then produced bigger pressure by the roller on push rod, it is achieved braking；And when needing after braking completes to continue to exercise, then the gas in the cavity between epithelium and bonnet is discharged from air inlet, push rod dish is mobile to the state with bonnet laminating under the effect of return spring, and now push rod is retracted inside protecgulum, then realize freeing brake.Due in the course of the work, roller can roll, and bearing pin needs the requirement of intensity then to cause the abrasive resistance of bearing pin relatively poor, roller rolling process easily causes and weares and teares inside roller and between bearing pin, thus affecting the normal use of equipment, serviceability reduces, and reduces service life simultaneously.And the setting of high-tensile strength brass bushing, both can improve wearability, reduce the abrasion between copper sheathing and roller, and the rotating property of roller can have been improved.
Junction between described protecgulum and bonnet is all outwardly formed flanging and close fit between the flanging on protecgulum and the flanging on bonnet；Being provided with anchor ear on the flanging of protecgulum with the flanging of bonnet, anchor ear fixes protecgulum and bonnet.This structure can more firmly fixing by protecgulum and bonnet, coordinate closely, seal is better.
Junction between described protecgulum and bonnet is all outwardly formed flanging, and the flanging of protecgulum is different with the length of the outwards bending of the flanging of bonnet, and wherein longer flanging is to shorter flanging one lateral buckling, and shorter flanging is wrapped in inside.This structure is convenient realize between protecgulum and bonnet fixing, and production cost is low, assembles convenient.
The durable type energy storage spring brake chamber that this utility model is obtained, is provided with lining between bearing pin and roller, can effectively raise the anti-wear performance between roller and bearing pin, thus improve the serviceability of equipment, reduces use cost.
