Description
Technical field
The utility model relates to a kind of wheel cylinder piston fast reposition device.
Background technique
The working procedure of automobile disc brake pad is as follows: the pressure that wheel cylinder relies on brake fluid to produce, and promote piston and move ahead, make brake block clamp brake disc, produce braking force, in the time that piston moves axially, piston packing produces resiliently deformable, in the time that braking stops, the pressure of brake fluid disappears, piston is no longer subject to the effect of brake fluid, and seal ring resiles, and makes piston mobile reset vertically, brake block resets simultaneously, and braking is removed.Disk type braker is not in the time braking, brake block and brake disc are that phase mutual friction should not occur, but, because the reset of piston is to rely on the elasticity of seal ring to complete, if piston is because of corrosion, the many reasons such as dust cause axial movable resistance to increase, add the aging of seal ring, the elasticity strength of seal ring just can not make piston fast reposition, even can not reset completely, this just makes brake block and brake disc that the time lengthening of friction occurs, thereby the wearing and tearing of aggravation brake block and brake disc, shorten the working life of brake block and brake disc, also can increase car resistance simultaneously, consume more multiple-energy-source, cause the waste of the energy.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of wheel cylinder piston fast reposition device is provided.
The utility model solves the technological scheme that its technical problem adopts: a kind of wheel cylinder piston fast reposition device, comprise the cylinder body of wheel cylinder, rear end of the cylinder block is provided with the oil inlet and outlet being communicated with inner chamber of cylinder block, inner chamber of cylinder block is provided with piston, between piston outer side surface and inboard wall of cylinder block, be provided with seal ring, piston nose has the cylindrical push rod that clamps brake disc generation braking force in the time that piston stretches out in order to promote brake block, cylindrical push rod center is provided with blind hole, in the annular space forming between cylindrical push rod and inboard wall of cylinder block, be provided with the spring being sleeved on cylindrical push rod, described cylinder body front end is provided with outside thread, cylinder body front end is by the outside thread end cap that has been threaded, end cap center is provided with for cylindrical push rod stretches out the through hole that indentation is passed through, end cap outer side surface is provided with the straight knurling of being convenient to staff and stirring end cap.
The beneficial effects of the utility model are: the utility model has installed spring additional between piston and end cap, when braking, piston moves ahead, by spring-compressed, in the time that braking stops, the pressure of brake fluid disappears, the reset of spring can help piston fast reposition, thereby shortened brake block and brake disc and occur time of friction, in the working life of having improved brake block and brake disc, reduce energy consumption.
