Problems solved by technology

[0002] The synchronizer plays a very important role in the shifting process of the car. At present, the inertial synchronizer is used more frequently. There are many domestic patents describing the synchronizer with similar structure, such as the public (announcement) number CN20286721U, a multi-cone surface Synchronizer, CN102182766A inner cone ring embedded synchronizer assembly, CN202065448U a new type of auxiliary box synchronizer assembly, these inertial synchronizers are characterized by relying on friction to achieve synchronization, but there are also occasional outages after shifting gears. The phenomenon of shifting gears, especially when the vehicle is driving on a bumpy road, will affect the driving safety of the vehicle; in addition, during the shifting process, shifting sticks often occur. strenuous

Embodiment Construction

[0014] Specific embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as Figure 4 As shown, a positioning groove 11 is provided on the spline tooth corresponding to the positioning protrusion 32 of the gear sleeve 1 and the slider. . When in neutral position, the positioning groove 11 in the middle position of the gear sleeve contacts with the top of the positioning protrusion 32 of the slider, and the elastic force provided by the spring of the slider ensures that the gear sleeve is in the neutral position; when the synchronizer shifts gears, The gear sleeve will move axially under the force of the shift fork. When the gear sleeve moves to the specified position, the limit groove 12 on the spline teeth of the gear sleeve just contacts the positioning protrusion 32 of the slider, and the replacement is completed. At the same time, the limit groove 12 and the positioning protrusion 32 play the role of limi...

Abstract

The invention provides an out-of-gear-preventive synchronizer gear sleeve. A positioning groove (11) is arranged on each spline tooth, corresponding to a positioning protrusion (32) of a slider, of a gear sleeve body (1), a limiting groove (12) is arranged on each of two sides of each positioning groove, and tooth thickness of part of the spline teeth is reduced. The out-of-gear-preventive synchronizer gear sleeve has the advantages that by adopting the above structure, when a synchronizer performs gear shifting, gear-shifting clamping stagnation is reduced, and out-of-gear phenomena are prevented, so that gear shifting performance of the synchronizer and traveling safety of a vehicle are improved.
