Further, the limit shaft is integrally formed with steel ball seat.
Further, the limit shaft has hollow structure.
Further, clamping screw is further included, the top of the self-locking hole is equipped with coordinates the internal thread being spirally connected with clamping screw.
Further, the spring base is additionally provided with the rod aperture for being passed through for gear level, the axis and rod aperture of the self-locking hole
Axis perpendicular.
Further, the self-locking hole is equipped with large-diameter portion and small diameter portion, the connection of the large-diameter portion and small diameter portion from top to bottom
Place is equipped with chamfering, and the steel ball seat is arranged on small diameter portion in a manner of clearance fit.
Further, the steel ball seat is made of nonmetallic materials.
Further, the surface of the steel ball seat is equipped with wearing layer.
Beneficial effects of the present invention：
The automotive transmission self-locking mechanism of the present invention, steel ball seat are axially sliding along self-locking hole under the elastic force effect of self-locking spring
Move, adapted to plus the arc groove and steel ball surface of steel ball seat lower surface so that arc groove can keep close face with steel ball
Contact, realizes pure rolling, thus prevents steel ball to be damaged because of surface unbalance stress, ensure the smooth of gear shift.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the structure diagram of the present invention.
Embodiment
Fig. 1 is the structure diagram of the present invention, as shown in the figure：The automotive transmission self-locking mechanism of the present embodiment, including set
Have the spring base 1 of self-locking hole 11, be equipped with self-locking spring 2 and steel ball 3 in the self-locking hole 11, the self-locking spring 2 and steel ball 3 it
Between be equipped with steel ball seat 4 along 11 axial slip of self-locking hole, the lower surface of the steel ball seat 4 is equipped with the arc adapted to 3 surface of steel ball
Connected in star 41；The spring base 1 is additionally provided with the rod aperture 12 for being passed through for gear level 9, the axis and rod aperture of the self-locking hole 11
12 axis perpendicular；Spring base further includes clamping screw 5, and the top of the self-locking hole 11 is equipped with coordinates spiral shell with clamping screw 5
The internal thread 11a connect；Gear level 9 passes through rod aperture 12, and top and the clamping screw 5 of self-locking hole 11 coordinate, and clamping screw 5 is pressed at the same time
Tight self-locking spring 2, steel ball 3 are located between self-locking spring 2 and gear level 9, and steel ball 3 (is also arc with the limiting groove on gear level 9
Shape) coordinate to realize the constraint of shift lever；Steel ball seat 4 under the elastic force effect of self-locking spring 2 along 11 axial slip of self-locking hole,
Adapted to plus the arc groove 41 and 3 surface of steel ball of 4 lower surface of steel ball seat so that arc groove 41 can keep close with steel ball 3
Face contact, realize pure rolling, thus prevent steel ball 3 to be damaged because of surface unbalance stress, ensure the smooth of gear shift.
In the present embodiment, the upper surface of the steel ball seat 4 is equipped with spacing in the cavity for being used to coaxially stretch into self-locking spring 2
Axis 42；The outside diameter of limit shaft 42 is roughly the same with the cavity width of self-locking spring 2, and limit shaft 42 can operative constraint after stretching into cavity
