Abstract
The utility model relates to a novel braking wheel cylinder subassembly, comprising a cylinder body, the cylinder body in be equipped with radial hole, be equipped with left piston and right piston in this radial hole, and this left side piston and right piston and radial hole's pore wall sliding fit, left piston and right piston between be equipped with the spring holder, the cover has return spring on this spring holder, the spring holder be fixed in a side end face of right piston on, and the axial direction line of the axial direction line of spring holder and right piston is in on the same straight line, the beneficial effects of the utility model are that: simple structure sets up in return spring's the outside and takes the spring holder for the spring can outwards not bent in frequent, quick compression process, thereby has guaranteed that the spring does not take place to warp, make brake performance stable, the vehicle safety of traveling.
Description
Technical field
This utility model belongs to drum brake assembly, particularly relates to the Novel braked wheel cylinder assembly in a kind of drum brake assembly.
Background technology
The frequent return deficiency of former wheel cylinder assembly causes piston catching phenomenon.As shown in Figure 1, the active force of wheel cylinder return is the returning place force of brake-shoe, stops the counteracting force of wheel cylinder piston return to include the frictional force of leather cup, the compression stress of spring, piston frictional force.The returning place force being only subject to when piston both sides is more than when the making a concerted effort of counteracting force stoping piston return, and piston just will not clamping stagnation；But there is return spring displacement, piston unbalance stress phenomenon, easily cause the problems such as brake fade, lock of controller, generation noise.
Summary of the invention
The purpose of this utility model is in that the deficiency overcoming prior art to exist, and provides a kind of Novel braked wheel cylinder assembly.
The purpose of this utility model completes by following technical solution, including cylinder body, is provided with radial direction through hole in described cylinder body, is provided with left piston and right piston in this radial direction through hole, and the hole wall of this left piston and right piston and radial direction through hole is slidably matched；It is provided with spring base between described left piston and right piston, this spring base is cased with return spring.
As preferably, described spring base is fixed on a side end face of right piston, and the longitudinal center line of the longitudinal center line of spring base and right piston is on same straight line.
The beneficial effects of the utility model are: simple in construction, at the arranged outside band spring base of return spring so that spring in compression process frequent, quick will not outwards bending, thus ensure that spring does not deform；Make braking ability stable, vehicle driving safety.
Accompanying drawing explanation
Fig. 1 is existing wheel cylinder modular construction schematic diagram.
Fig. 2 is structural representation of the present utility model.
Label in accompanying drawing is respectively as follows: 1, cylinder body；2, left piston；3, right piston；4, spring base；5, return spring；11, radial direction through hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model done detailed introduction: as shown in Figure 2, this utility model includes cylinder body 1, it is provided with radial direction through hole 11 in described cylinder body 1, in this radial direction through hole 11, it is provided with left piston 2 and right piston 3, and the hole wall of this left piston 2 and right piston 3 and radial direction through hole 11 is slidably matched；It is provided with spring base 4 between described left piston 2 and right piston 3, this spring base 4 is cased with return spring 5.
Described spring base 4 is fixed on a side end face of right piston 3, and the longitudinal center line of the longitudinal center line of spring base 4 and right piston 3 is on same straight line.
Deform when the spring base 4 that this utility model increases can prevent return spring 5 from compressing, shift, make braking ability stable, vehicle driving safety.
This utility model is not limited to above-mentioned embodiment, no matter making any change, every employing structural design provided by the utility model on its shape or material are constituted, being all a kind of deformation of the present utility model, being all considered as within this utility model protection domain.
