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
The present invention relates to a kind of automobile synchronizer technology, is that a kind of car is used the synchronizer soldered tooth 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 the traditional design soldered tooth is short with the length of action of tooth cover internal 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 with tooth cover and engages length of action, engagement is stable, firm, the car synchronizer soldered tooth that usage safety performance is high.
Technological scheme provided by the invention is: a kind of car is used the synchronizer soldered tooth; Comprise lasso and be distributed in a plurality of external tooths on the lasso outer circle wall along axial setting of lasso; Its technical characterstic is that said external tooth one side exterior edge face forms the cutting edge shape, and the cutting edge inclination at cutting edge place, external tooth one side exterior edge face is 1-5 °.
The invention has the beneficial effects as follows: external tooth one side exterior edge face forms the cutting edge shape; Cutting edge place, internal tooth one side exterior edge face 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 tooth cover internal 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 plan view of Fig. 1.
Among the figure: lasso 1, external 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 with the synchronizer soldered tooth and axially is provided with along lasso and be distributed in a plurality of external tooths 2 on the lasso outer circle wall, external tooth 2 one side exterior edge faces form the cutting edge shape, the cutting edge inclination 3 at cutting edge place, external tooth one side exterior edge face is 1-5 °.Among the figure: T is a soldered tooth gear shift length of action, and Y is a tooth depth, has increased (tan6-tan2) Y=0.07Y when length of action T is than 6o when the cutting edge inclination 3 at external tooth angle of lock place is 2o.
Claims (1)
1. a car is used the synchronizer soldered tooth, comprises lasso and is distributed in a plurality of external tooths on the lasso outer circle wall along axial setting of lasso, and it is characterized in that: said external tooth one side exterior edge face forms the cutting edge shape, and the cutting edge inclination at cutting edge place, external tooth one side exterior edge face is 1-5 °.
