In the clutch, a cylinder body is axially positioned and connected with a limiting seat through a clamping jaw, a limiting pad is in clearance fit with a piston and is axially supported by the limiting seat, a main leather cup is in interference fit with the cylinder body and is axially supported by the limiting pad, and the piston is in interference fit with the main leather cup; the piston is provided with a spiral groove for oil supplement, and the spiral groove extends from the end face of the piston to the corresponding position of the inner lip of the main leather cup. The utility model discloses a clutch master cylinder during operation brake fluid is at the circulation of making a round trip in pressure chamber and oil supplementing chamber, and the passageway because of making a round trip to circulate is helical structure, and it is littleer than traditional oil supplementing hole to the damage of packing cup, and processing is very convenient, direct extrusion can.
Description
Technical Field
The utility model relates to a novel clutch master cylinder is used to car, especially, has related to a novel clutch master cylinder oil supplementing structure of car.
Background
In the clutch master cylinder used currently in the market, once a sealing leather cup is damaged by burrs at the sharp corner of a piston, the damage of the leather cup is aggravated when pressure is built to continue working until the leather cup is torn, and finally the clutch master cylinder is caused to lose efficacy. Therefore, in the prior art, the sealing leather cup is easily damaged by burrs at the sharp corner of the piston, and the damage of the leather cup is aggravated when the sealing leather cup continues to work to build pressure until the leather cup is torn, and finally the clutch main cylinder fails.
SUMMERY OF THE UTILITY MODEL
Seal leather cup easily receives piston closed angle burr damage among the prior art, and leather cup damage will aggravate when continuing work to establish pressure, tears until the leather cup, finally leads to the technical problem that clutch master cylinder became invalid, the utility model provides a novel clutch master cylinder oil supplementing structure of car.
The utility model discloses a following technical scheme can solve:
the utility model discloses an automobile clutch includes cylinder body, piston, main leather cup, spacing pad and spacing seat, and the piston is installed in cylinder body jar downthehole, and the cover is equipped with main leather cup, spacing pad and spacing seat along the axial in proper order between cylinder body jar hole and the piston, and the cylinder body passes through jack catch axial positioning with spacing seat to be connected, and spacing pad passes through clearance fit and supports through spacing seat axial with the piston, and main leather cup and cylinder body interference fit and support through spacing pad axial, and piston and main leather cup interference fit; the piston is provided with a spiral groove for oil supplement, and the spiral groove extends to the corresponding position of the inner lip of the main leather cup from the end surface of the piston so as to realize normal oil supplement of the clutch main cylinder and normal function of the clutch main cylinder.
The spiral groove is formed by extrusion forming on the piston.
The cylinder body is made of metal materials.
The piston, the main leather cup and the limiting pad are made of flexible materials.
The limiting seat is made of metal materials.
The utility model has the advantages that:
the utility model discloses a clutch master cylinder piston configuration optimization, the benefit oil is realized through spiral benefit oil groove, and this spiral can not produce the damage to the leather cup, when realizing the normal oil supplementing function of clutch master cylinder, has improved the work of clutch master cylinder.
Drawings
Fig. 1 is a novel oil supplementing structure of a clutch main cylinder of an automobile.
Fig. 2 shows a spiral groove structure for oil supply in the piston 2.
In the figure: 1. the device comprises a cylinder body, 2, a piston, 3, a main leather cup, 4, a limiting pad, 5, a limiting seat, a claw, b and a spiral groove.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model discloses an automobile clutch includes cylinder body 1, piston 2, main leather cup 3, spacing pad 4 and spacing seat 5, piston 2 installs in 1 jar of hole of cylinder body, it is equipped with main leather cup 3 to overlap in proper order along the axial between 1 jar of hole of cylinder body and the piston 2, spacing pad 4 and spacing seat 5, cylinder body 1 is connected through jack catch a axial positioning with spacing seat 5, spacing pad 4 passes through clearance fit and supports through spacing seat 5 axial with piston 2, main leather cup 3 and 1 interference fit of cylinder body support through spacing pad 4 axial supports, piston 2 and 3 interference fit of main leather cup, spacing pad 4 and spacing seat 5 clearance fit.
As shown in fig. 2, the piston 2 is provided with a spiral groove b for oil supplement, and the spiral groove b extends from the end surface of the piston 2 to the position corresponding to the inner lip of the main leather cup 3, so that the working cavity of the clutch master cylinder and the oil supplement cavity are effectively communicated, and the normal circulation of brake fluid is realized.
The utility model discloses a clutch master cylinder extrudes the helicla flute on the piston, and this helicla flute is obtained by extrusion, does not have closed angle and burr, and smoothness such as fillet is excessive, can not produce the damage to the leather cup, when realizing the normal oil supplementing function of clutch master cylinder, has improved the working life of clutch master cylinder.
During the operation of the clutch, oil enters the main cylinder working cavity from the oil supplementing cavity along the spiral groove b, so that an oil supplementing process is formed, and the brake fluid circulates back and forth during the operation of the clutch main cylinder.
The utility model discloses a clutch master cylinder during operation brake fluid is at the circulation of making a round trip in pressure chamber and oil supplementing chamber, and the passageway because of making a round trip to circulate is helical structure, and it is littleer than traditional oil supplementing hole to the damage of packing cup, and processing is very convenient, direct extrusion can.
The above detailed description is provided for illustrative purposes, and is not intended to limit the present invention, and any modifications and variations of the present invention are within the spirit and scope of the following claims.
