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
The present invention relates to a kind of automobile synchronizer technology, is that a kind of car is used 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 the double-clutch automatic speed-change case; Receive the restriction of spatial position, synchronizer all adopts short stroke formula synchronizer, and traditional design tooth cover engaging tooth is short with the length of action of soldered tooth and cooperate unstable; Be prone to become flexible, skid, lose rank, have application risk.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of simple in structurely, can effectively increase tooth cover and soldered tooth length of action, engagement is stable, firmly, the car synchronizer gear sleeve that usage safety performance is high.
Technological scheme provided by the invention is: a kind of car is used synchronizer gear sleeve; Comprise lasso and be distributed in a plurality of internal tooths on the lasso inner peripheral wall along axial setting of lasso; Its technical characterstic is that exterior edge face, said 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 said internal tooth, width are identical, and the width of internal tooth two side portions is gradually wide from inside to outside, thickness is gradually thin from inside to outside.
The invention has the beneficial effects as follows: 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; Help improving engagement stability, soundness, safety in utilization, guarantee the reliability of gearbox gear-shift.
Description of drawings
Fig. 1 is a structural representation of the present invention;
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
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1, shown in 2; A kind of car comprises lasso 1 and is distributed in a plurality of internal tooths 2 on the lasso inner peripheral wall along axial setting of lasso 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 °, and the intermediate portion thickness of internal tooth 2, width are identical, and the width of internal tooth two side portions is gradually wide from inside to outside, thickness is gradually thin from inside to outside.Among the figure: T is a tooth cover gear shift length of action; Y is a 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, helps improving engagement stability, soundness, safety in utilization, guarantees the reliability of gearbox gear-shift.
Claims (2)
1. a car is used synchronizer gear sleeve, comprises lasso and is distributed in a plurality of internal tooths on the lasso inner peripheral wall along axial setting of lasso, and it is characterized in that: exterior edge face, said 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 according to claim 1 is used synchronizer gear sleeve, it is characterized in that: the intermediate portion thickness of said internal tooth, width are identical, and the width of internal tooth two side portions is gradually wide from inside to outside, thickness is gradually thin from inside to outside.
