Technical field
The utility model relates to a kind of and matched clutch of mechanical transmission, in particular to a kind of range keeps off shift fork.
Background technique
Pull-type and two kinds of pushing-type are divided into according to the direction of motion of release bearing with the matched clutch of mechanical transmission, drawn
Formula clutch is more and more extensive due to applying the characteristics of itself, and range keeps off shift fork fork as wherein crucial part, works as boost pump
Power output pushes assister bar, acts on one end of range gear shift fork fork, and disengaging yoke axis rotates disengaging yoke as fulcrum,
The other end of disengaging yoke pushes release bearing, makes clutch separation or combination.
And for existing range gear shift fork, due to self structure limitation, carried out with release bearing
When cooperating, high-frequency vibration that power source is transmitted and the noise generated by vibration are often passed into separation together
Bearing and driver, to affect the comfort of gear shift operation, while because vibration will also result in range gear shift fork with separate
Phase mutual friction between bearing so as to cause the abrasion of transmission system components, and reduces making for transmission system components
With performance and service life.
