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 gear sleeve meshing teeth and engaging teeth is short and the cooperation is unstable and easy to loosen. , slipping, and gear loss, there are risks in use

Embodiment Construction

[0010] The present invention will be further described below in conjunction with drawings and embodiments.

[0011] figure 1 , 2 As shown, a synchronizer gear sleeve for a car includes a ferrule 1 and a plurality of internal teeth 2 arranged on the inner peripheral wall of the ferrule along the axial direction of the ferrule. The blade inclination angle at the cutting edges on both sides of the inner teeth is 1-5°. The thickness and width of the middle part of the inner teeth 2 are the same. In the figure: T is the meshing length of gear bushing shifting, Y is the tooth height, when the blade inclination angle at the locking angle of the gear bushing is 2o, the meshing length T is increased (tan6-tan2)Y=0.07Y compared with 6o, and the engaging teeth The meshing length becomes longer, which is conducive to improving the meshing stability, firmness, and safety in use, and ensures the reliability of the gearbox shifting.

Abstract

The invention relates to a toothed sleeve of synchronizer for a passenger car. The toothed sleeve comprises a ferrule, and a plurality of internal teeth which are arranged along the axial direction of the ferrule and evenly distributed on the inner circumferential wall of the ferrule, wherein the outer end surfaces on the two ends of the internal teeth are in cutting edge shapes; cutting edge inclinations at cutting edges on the outer end surfaces on the two sides of the internal teeth are 1-5 DEG; the thicknesses and the widths of the middle parts of the internal teeth are the same; and the widths of the two side parts of the internal teeth are gradually increased from inside to outside and the thicknesses of the two side parts of the internal teeth are gradually decreased from inside to outside. The outer end surfaces on the two sides of the internal teeth are in the cutting edge shapes, and the cutting edges on the outer end surfaces on the two sides of the internal teeth are positioned at ferrule locking corners and the cutting edge inclinations are 1-5 DEG; and compared with traditional cutting edge inclinations greater than 6 DEG, the cutting edge inclinations of 1-5 DEG has the longer meshing length with connecting teeth, so the meshing stability, the firmness and the use safety are beneficially improved and the reliability of gear shifting of a speed changing box is guaranteed.

Description

technical field [0001] The invention relates to an automobile synchronizer technology, in particular to a synchronizer tooth sleeve 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. Due to the limitation of space, the synchronizers are all short-stroke synchronizers. The meshing length of the traditionally designed gear sleeve meshing teeth and engaging teeth 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 gear sleeve with simple structure, which can effecti...
