Description

Clutch working cylinder ball sleeve integrated with shield mounting structure

Technical Field

The utility model relates to a component in a clutch, in particular to a clutch working cylinder ball sleeve integrated with a protective cover mounting structure,

background

With the development of the automobile industry and plastic technology, the performance requirements of a main engine plant on the clutch working cylinder are higher and higher. A traditional clutch working cylinder push rod directly acts on a shifting fork of a gearbox, and friction rotation is easily generated during movement to generate abnormal sound. Meanwhile, because the protective cover is directly assembled on the push rod, when the push rod reciprocates, external silt is easy to enter the clutch working cylinder to scratch the leather cup, so that the product fails.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a clutch working cylinder ball cover of integrated guard shield mounting structure is provided, the ball cover is in the same place with the push rod joint, can produce relative rotation, has eliminated the abnormal sound that push rod and shift fork produced because of the friction when increasing the push rod pivot angle.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model discloses a ball cover rear end periphery is equipped with the ring groove, and the one end tip suit of guard shield is in the ring groove, is equipped with the ball socket in the middle of the rear end, and open at the internal surface center of ball socket has the cross recess, and the cross recess is used for storing the grease, eliminates the abnormal sound, avoids the noise, and the interior week of ball socket is extended outward and is equipped with the jack catch of equipartition, and a push rod tip suit is in the ball socket and by the local parcel of jack catch.

The jack catch is a protruding structure which is connected to the inner circumferential surface of the ball sleeve close to the opening of the ball socket, a gap exists between the outer side face of the protrusion and the inner circumferential surface of the opening of the ball socket, the inner side face of the protrusion is in close contact with the end part of the push rod, so that the protrusion has certain elastic movement along the radial direction of the ball socket, the outer side of the equator of the end part of the push rod is surrounded by the ball socket, and the inner side of the equator.

Eight clamping jaws are arranged on the ball socket extension of the ball sleeve and are uniformly distributed at intervals along the circumference.

The protective cover is sleeved in the circular groove in an interference manner, and can effectively prevent silt from entering the clutch working cylinder to scratch the leather cup after the protective cover is installed, so that the fault rate is reduced.

The ball sleeve is made of plastic materials.

The utility model has the advantages that:

the utility model discloses clutch working cylinder ball cover has increased the allowable work pivot angle, has eliminated the abnormal sound that push rod and shift fork produced because of the friction, simultaneously, is equipped with the ring groove who is used for installing the guard shield on the ball cover, can prevent effectively behind the installation guard shield that silt from getting into clutch working cylinder scratch leather cup to reduce the fault incidence.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, 5 and 6, a ball socket for mounting a ball head of a push rod is arranged in the middle of the rear end of a ball sleeve 1, the ball socket of the ball sleeve 1 is sleeved on the ball head end of the push rod 2, the front end of the ball sleeve 1 is mounted on a shift fork of a gearbox, and when the shift fork moves to generate a swing angle, the ball sleeve 1 and the push rod 2 can rotate relatively, so that the head of the push rod 2 rotates in the ball sleeve 1 to ensure that the push rod 2 keeps relative linear motion.

As shown in fig. 2, the periphery of the rear end of the ball sleeve 1 is provided with a circular groove 6, the protective cover 3 is of an elastic telescopic cylinder structure, one end part of the protective cover 3 is sleeved in the circular groove 6 and is in interference connection, the protective cover 3 can play a good sealing role after being installed, and silt can be effectively prevented from entering the clutch working cylinder to scratch a leather cup, so that the failure occurrence rate is reduced.

As shown in fig. 2 and 3, eight claws 4 are arranged on the outer periphery of the inner circumference of the ball socket at intervals, one end of the push rod 2 is sleeved in the ball socket and is partially wrapped by the claws 4, the end of the push rod 2 is in contact connection with the cross-shaped groove 5, and the other end of the push rod 2 extends out of the shield 3, so that the push rod ball head can be installed quickly.

The jack catch 4 is for setting up the protruding structure of connecting at ball cover 1 near the open-ended inner peripheral surface of ball socket, and protruding root and 1 inner peripheral surface of ball cover keep fixed connection, have the clearance between protruding lateral surface and the open-ended inner peripheral surface of ball socket, protruding medial surface and 2 tip in close contact with of push rod for the protruding radial certain elastic motion that has along the ball socket that has, 2 tip of push rod are surrounded by a plurality of archs.

As shown in fig. 4, the center of the inner surface of the ball socket is provided with a cross-shaped groove 5, and the cross-shaped groove 5 is used for storing grease, so that the lubricity between the push rod 2 and the ball sleeve 1 can be improved, and abnormal sound generated by friction can be avoided.

The utility model discloses ball cover simple structure, it is convenient to use, has increased the work pivot angle of product, has avoided the noise that push rod and shift fork produced because of the friction, simultaneously, can play fine sealed effect after the guard shield installation, can prevent effectively that silt from getting into clutch working cylinder scratch leather cup, has important meaning to improving after sale.
