CN202768669U - Synchronizer gear sleeve for car - Google Patents

Abstract

The utility model relates to a synchronizer gear sleeve for a car. The synchronizer gear sleeve for the car comprises a ferrule and a plurality of inner teeth which are evenly distributed on the inner circumferential wall of the ferrule along the axial direction of the ferrule, wherein outer end faces of two sides of each inner tooth form a cutting edge shape, a tool cutting edge inclination of the cutting edge place of the outer end faces of two sides of each inner tooth is 1degree-5degrees, thicknesses and widths of middle portions of the inner teeth are same, widths of two lateral portions of each inner tooth gradually widen from inside to outside, thicknesses of the two lateral portions of each inner tooth gradually thin from the inside to outside, the outer end faces of two sides of each inner tooth form the cutting edge shape, the cutting edge place of the outer end faces of two sides of each inner tooth is a gear sleeve locking angle place, and the tool cutting edge inclination of the cutting edge place of the outer end faces of each inner tooth is 1degree-5degrees, and is greater than 6 degrees (compared with a traditional tool cutting edge inclination). The meshing length between joint teeth and the outer end faces of two sides of each inner tooth is lengthened, and the synchronizer gear sleeve for the car is beneficial to improving stability of meshing, solidity, and safety of use, and guarantees stability of shifting of a speed changing box.

Description

A kind of car synchronizer gear sleeve

Technical field

The utility model relates to a kind of automobile synchronizer technology, is a kind of car synchronizer gear sleeve specifically.

Background technique

Automobile synchronizer is in order to solve automobile engine speed and the inconsistent mechanical device of gearbox rotating speed in gear shift operation, and he can avoid hanging gear whine when not performing, eliminating gearshift etc. effectively.Existing sedan gear-box mostly uses dual-clutch transmission, be subject to the restriction of spatial position, synchronizer all adopts short stroke formula synchronizer, and traditional design tooth cover engaging tooth is shorter with the length of action of soldered tooth and cooperate unstable, easily become flexible, skid, lose rank, have application risk.

Summary of the invention

In order to solve deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and can effectively increase tooth cover and soldered tooth length of action, and engagement is stable, firm, the car synchronizer gear sleeve that usage safety performance is high.

The technological scheme that the utility model provides is: a kind of car synchronizer gear sleeve, comprise lasso and along lasso a plurality of internal tooths that are distributed on the lasso inner peripheral wall are set axially, its technical characterstic is that exterior edge face, described internal tooth both sides forms the cutting edge shape, and the cutting edge inclination at cutting edge place, exterior edge face, internal tooth both sides is 1-5 °.

Further, the intermediate portion thickness of described internal tooth, width are identical, the width of internal tooth two side portions from inside to outside gradually wide, thickness is gradually thin from inside to outside.

The beneficial effects of the utility model are: exterior edge face, internal tooth both sides forms the cutting edge shape, cutting edge place, exterior edge face, internal tooth both sides is tooth cover angle of lock place, cutting edge inclination 1-5 °, compare traditional cutting edge inclination〉6 °, elongated with the length of action of soldered tooth, be conducive to improve Meshing stability, soundness, safety in utilization, guarantee the reliability of gearbox gear-shift.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the worm's eye view of analysing and observe of Fig. 1.

Among the figure: lasso 1, internal tooth 2, cutting edge inclination 3.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Shown in Fig. 1,2, a kind of car comprises lasso 1 and along lasso a plurality of internal tooths 2 that are distributed on the lasso inner peripheral wall is set axially with synchronizer gear sleeve, exterior edge face, internal tooth 2 both sides forms the cutting edge shape, the cutting edge inclination at cutting edge place, exterior edge face, internal tooth both sides is 1-5 °, the intermediate portion thickness of internal tooth 2, width are identical, the width of internal tooth two side portions from inside to outside gradually wide, thickness is gradually thin from inside to outside.Among the figure: T is tooth cover gear shift length of action, Y is tooth depth, increased (tan6-tan2) Y=0.07Y when length of action T is than 6o when the cutting edge inclination at tooth cover angle of lock place is 2o, the length of action of soldered tooth is elongated, be conducive to improve Meshing stability, soundness, safety in utilization, guarantee the reliability of gearbox gear-shift.

Claims (2)

1. a car synchronizer gear sleeve comprises lasso and along lasso a plurality of internal tooths that are distributed on the lasso inner peripheral wall is set axially, and it is characterized in that: exterior edge face, described internal tooth both sides forms the cutting edge shape, and the cutting edge inclination at cutting edge place, exterior edge face, internal tooth both sides is 1-5 °.

2. a kind of car synchronizer gear sleeve according to claim 1 is characterized in that: the intermediate portion thickness of described internal tooth, width are identical, the width of internal tooth two side portions from inside to outside gradually wide, thickness is gradually thin from inside to outside.
