Groove；Ball annular groove is provided with the shift fork leg lower end inside face, the ball annular groove is arranged around the mounting hole, the rolling
Small ball, the small ball and the contacts side surfaces of the rolling ring are provided with pearl annular groove.Such setting can allow bearing pin with dialling
Connection between fork leg is even closer, so as to more allow rolling ring more stably to rotate.
Further, elastic swelling layer is provided with the neck.Such setting can allow between bearing pin and shift fork leg
Connection it is more stable.
Further, the inner of the bearing pin is provided with the head of a nail.
Further, it is provided with spring leaf between the head of a nail and rolling ring.Such setting can avoid rolling ring significantly
Rock.
Further, it is provided with bushing between the rolling ring and the bearing pin.Such setting can reduce rolling ring and pin
Frictional resistance between axle.
Further, it is provided with oil leab in the bushing.
Further, the oil leab is the Z-shaped oil duct for being arranged on the bushing medial surface.The setting of Z-shaped oil duct can
To make the rotation of rolling ring more smooth.
Further, the rolling ring is made of bearing steel material.
A kind of disengaging yoke Stability Analysis of Structures of the present utility model, cause bearing pin with dialling using the cooperation between fixture block and neck
It is relatively stable between fork leg, the more stable smoothness of rolling of rolling ring so that the contact between disengaging yoke and release bearing is more
Closely.
In order to more fully understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the enlarged diagram at the utility model shift fork leg.
Fig. 3 is the left view at the utility model shift fork leg.
Embodiment
Fig. 1-3 are referred to, the utility model discloses a kind of disengaging yoke, including shift fork body 10 and shift fork leg 20, institute
The upper end for stating shift fork leg 20 is connected with the shift fork body 10；The lower end of the shift fork leg 20 is provided with mounting hole 21, the peace
Dress is provided with rolling mechanism at hole 21；The rolling mechanism includes bearing pin 31 and rolling ring 32, and the rolling ring 32 is set in the pin
The inner of axle 31 can simultaneously rotate relative to the bearing pin 31, and the outer end of the bearing pin 31 is provided with fixture block 311, the mounting hole 21
Lateral surface is provided with neck 22, and the fixture block 311 is caught in into the neck 22；The fixture block 311 is cross, the neck
22 are and the 311 corresponding cross recess of fixture block.
