Problems solved by technology

Most of the existing car gearboxes use dual-clutch automatic gearboxes. Due to the limitation of space, the synchronizers are all short-stroke synchronizers. The meshing length of the traditionally designed engaging teeth and the inner teeth of the gear sleeve is short and the cooperation is unstable and easy to loosen. , slipping, and gear loss, there are risks in use

Embodiment Construction

[0009] The present invention will be further described below in conjunction with drawings and embodiments.

[0010] figure 1 , 2 As shown, a synchronizer engaging tooth for a car includes a ferrule 1 and a plurality of external teeth 2 arranged in the axial direction of the ferrule and evenly distributed on the outer peripheral wall of the ferrule. The outer end surface of one side of the external teeth 2 forms a cutting edge. The blade inclination angle 3 at the edge of the outer end surface of the outer tooth side is 1-5°. In the figure: T is the meshing length of the engaging teeth, and Y is the tooth height. When the blade inclination angle 3 at the locking angle of the outer teeth is 2o, the meshing length T is increased (tan6-tan2)Y=0.07Y compared to 6o.

Abstract

The invention relates to a synchronizer jointing tooth for a car. The synchronizer jointing tooth comprises a sleeve ring, and a plurality of external teeth axially uniformly distributed on the peripheral wall of the sleeve ring along the sleeve ring, wherein the external end face of one side of each external tooth is in a shape of cutting edge; and an edge at the cutting edge on the external end face of one side of each external tooth has the inclination angle of 1 to 5 degrees. According to the synchronizer jointing tooth for the car, the external end face of one side of each external tooth is in a shape of cutting edge, the cutting edge on the external end face of one side of an internal tooth is a tooth sleeve locking angle, the edge has the inclination angle of 1 to 5 degrees; and compared with the traditional edge inclination angle of 6 degrees, the edge provided by the invention has the advantages that the engaging length of the internal tooth of the tooth sleeve is increased, so that the stability and firmness in engaging and the safety in use can be improved; and the reliability of a gearbox in shifting is ensured.

Description

technical field [0001] The invention relates to an automobile synchronizer technology, in particular to a synchronizer engaging tooth for a car. Background technique [0002] The car synchronizer is a mechanical device to solve the inconsistency between the engine speed and the gearbox speed during the shifting operation of the car. It can effectively prevent the gear from being shifted and eliminate the gear noise when shifting. Most of the existing car gearboxes use dual-clutch automatic gearboxes. Limited by the space position, the synchronizers are all short-stroke synchronizers. The meshing length of the traditionally designed engaging teeth and the inner teeth of the gear sleeve is short and the cooperation is unstable and easy to loosen. , slipping, and gear loss, there are risks in use. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a car synchronizer engaging tooth with simple structure, whic...
