The purpose of the movement of set 1 is provided with the coating of predetermined thickness at the second confined planes 15, and the impulse force hit is alleviated with effective.At other
In embodiment, a shelves gear 3 can also set the coating of predetermined thickness, i.e., one grade relative to the circumferential position of the second confined planes 15
The coating of predetermined thickness is set at gear position limiting face 32, effectively to alleviate both shock impulse forces.
Similarly, when needing to be linked into third gear, shift fork promotes synchronizer gear sleeve 1 to move.Now the rotation of synchronizer ring assembly 6 is fast
The velocity of rotation close to driving gear 2 is spent, with the movement of synchronizer gear sleeve 1, the internal spline 12 of synchronizer gear sleeve 1 is (referring to figure
1) engaged with the third gear conjunction gear 41 of third gear 4.Due to the internal spline flank of tooth 13 of internal spline 12 (referring to Fig. 1) (referring to Fig. 1)
The coating of predetermined thickness is provided with, the combination flank of tooth 22 (referring to Fig. 3) of third gear conjunction gear 41 is also equipped with the coating of predetermined thickness,
Therefore, in both engagement processes, stress between the two can be buffered effectively.When synchronizer gear sleeve 1 and third gear tooth
After the engagement of wheel 4, synchronizer gear sleeve 1 also continues to be acted on by remaining gear shifting force, so as to continue the direction shifting to third gear 4
It is dynamic.Now, the first confined planes 14 that the circumferential end faces of synchronizer gear sleeve 1 are set hit third gear 4, and limits synchronization device is reached with this
The purpose of the movement of tooth set 1.The coating of predetermined thickness is provided with the first confined planes 14, the impulse force hit is alleviated with effective.
In other embodiment, third gear 4 can also set the coating of predetermined thickness relative to the circumferential position of the first confined planes 14, i.e.,
The coating of predetermined thickness is set at third gear confined planes 42, effectively to alleviate both shock impulse forces.
Further, between synchronizer gear sleeve 1 and driving gear 2 working condition and coating, which is set, is equally applicable to other
The gear shifting action of gear.
