Abstract
The invention discloses a spring protecting device in a brake cylinder. The spring protecting device in the brake cylinder comprises a cylinder body, a radial through hole is formed in the cylinder body, a left piston and a right piston are arranged in the radial through hole, the left piston and the right piston are in slide fit with the hole wall of the radial through hole, a spring is connected between the left piston and the right piston, the positions, on the two sides of the radial through hole, of the cylinder body are respectively provided with a dustproof cover, and an oil nozzle which is communicated with the radial through hole is formed in the cylinder body. A guide sleeve is arranged on the outer side of the spring, and the length of the guide sleeve is smaller than the length of the spring. The spring protecting device is simple in structure, the guide sleeve is arranged on the outer portion of the spring, the spring is protected in the quick retracting process of the spring, the spring can not be deformed, and the service life of the spring is guaranteed.
Description
Technical field
The present invention relates to automotive brake field, be specifically related to a kind of wheel cylinder inner spring protective gear.
Background technique
Wheel cylinder generally relies on pressurized air or oil to enter master cylinder, and promote a set of base apparatuses such as piston and play braking action, be a part of automotive brake, for generation of the power that hinders vehicle movement or movement tendency, i.e. braking force.
In working procedure, if the oil pressure of wheel cylinder inner chamber or pressure change are excessive, will cause the piston of wheel cylinder inside to produce fast moving, and the spring of connection piston also can be thereupon flexible fast, thereby cause the distortion of spring.
Summary of the invention
The object of this invention is to provide a kind of wheel cylinder inner spring protective gear, at the outer installment guide pin bushing of spring, protect spring, make it can not produce distortion.
Technological scheme of the present invention is as follows:
A kind of wheel cylinder inner spring protective gear, include cylinder body, it is characterized in that: in described cylinder body, be provided with radial direction through hole, in described radial direction through hole, be provided with left and right piston, described left and right piston and the hole wall of radial direction through hole are slidably matched, and between left and right piston, be connected with spring, be positioned on the cylinder body of described radial direction through hole both sides and be separately installed with dust-proof cover, described cylinder body is provided with oil nozzle or the valve that leads to radial direction through hole; The outside of described spring is provided with guide pin bushing, and the length of described guide pin bushing is less than the length of spring.
Described wheel cylinder inner spring protective gear, is characterized in that: the inner side of described left and right piston is respectively equipped with leather cup.
Beneficial effect of the present invention:
The present invention is simple in structure, at the outer installment guide pin bushing of spring, in the process of spring quick-expansion, protects spring, makes it can not produce distortion, has ensured the working life of spring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Referring to Fig. 1, a kind of wheel cylinder inner spring protective gear, include cylinder body 1, in cylinder body 1, be provided with radial direction through hole 6, be provided with left and right piston 3,4 in radial direction through hole 6, the hole wall of left and right piston 7,4 and radial direction through hole 6 is slidably matched, and be connected with spring 2 between left and right piston 7,4, for fixing spring 2, be positioned on the cylinder body 1 of radial direction through hole 6 both sides and be separately installed with dust-proof cover 5, cylinder body 1 is provided with the oil nozzle that leads to radial direction through hole 6; The outside of spring 2 is provided with rubber guide pin bushing 8, because the stretch capability of rubber guide pin bushing 8 is poorer than spring 2, so require the length of rubber guide pin bushing 8 to be less than the length of spring 2.
Further, the inner side of left and right piston 7,4 is respectively equipped with leather cup 3.
Claims (2)
1. a wheel cylinder inner spring protective gear, include cylinder body, it is characterized in that: in described cylinder body, be provided with radial direction through hole, in described radial direction through hole, be provided with left and right piston, described left and right piston and the hole wall of radial direction through hole are slidably matched, and between left and right piston, be connected with spring, be positioned on the cylinder body of described radial direction through hole both sides and be separately installed with dust-proof cover, described cylinder body is provided with oil nozzle or the valve that leads to radial direction through hole; The outside of described spring is provided with guide pin bushing, and the length of described guide pin bushing is less than the length of spring.
2. wheel cylinder inner spring protective gear according to claim 1, is characterized in that: the inner side of described left and right piston is respectively equipped with leather cup.
