Abstract
The utility model pertains to the car manufacturing field, in particular to a car speeder shifting device, comprising a shaft, low speed gear roller pins, a low speed gear, a gear sleeve, high speed gear roller pins, a thrust plate and a high speed gear. The low speed gear is idly sleeved on a shaft through the low speed gear roller pins, the high speed gear is idly sleeved on the shaft through the high speed gear roller pins, and the gear sleeve is arranged on the shaft and can only move on the shaft in the axial direction. The utility model is characterized in that: the engaging teeth of the gear sleeve and the engaging teeth of the high speed gear and the low gear both adopt a single slope chamfer. The utility model employs the movement along the axial direction of the gear sleeve, the engaging teeth of the gear sleeve and the engaging teeth of the gear are engaged with each other and transfer the torque and realize the shifting. The single slope engaging teeth adopted in the engaging process of engaging teeth smoothes the engaging and decreases the impact, thus improving the abrasion resistance of the engaging teeth and prolonging the service life.
Description
Technical field
The utility model belongs to the automobile making class, specifically is a kind of automobile speed variator shift device.
Background technique
At present, automobile speed variator shift is finished with synchronizer, toothholder tooth cover or shifting slide gear basically, shifting slide gear is many to be used in low gear gearbox, existing most of soldered tooth engagement gear shift of adopting toothholder tooth cover, existing soldered tooth engagement Leading end chamfer generally adopts the symmetric double ramp structure, its principle be engage a gear preceding two treat the speed discrepancy of engaging elements have just have negative, the inclined-plane different during engage a gear according to the positive and negative use of speed discrepancy.Because speed changer all develops to many grades of change directions at present, and odd-side is all arranged basically, because of odd-side adopts large speed ratio, speed discrepancy is positive and negative constant, and existing soldered tooth double inclined plane structure is simple and direct inadequately, and operational safety is poor.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, a kind of more reasonable structure is provided, makes automobile speed variator shift device simpler, that use is more reliable, monocline surface chamfer soldered tooth is adopted in engagement more smoothly.
The technical solution of the utility model is as follows:
A kind of automobile speed variator shift device, comprise axle, low speed gear needle roller, low speed gear, tooth cover, high gear needle roller, thrust plate, high gear, low speed gear is placed on the axle by the low speed gear needle roller, high gear is placed on the axle by the high gear needle roller, tooth is sleeved on the axle can only do axial motion, it is characterized in that: the soldered tooth of tooth cover and the soldered tooth of high low speed gear adopt the monocline surface chamfer.
The utility model is by the axial motion of tooth cover, and torque is transmitted in the soldered tooth engagement of the soldered tooth of tooth cover and gear, realizes gear shift, in the soldered tooth engagement process, adopt monocline face soldered tooth, make engagement more smooth and easy, the minimizing that is hit, increased the wear resistance of soldered tooth simultaneously, life-saving.

Fig. 2 is the A-A sectional view (amplification) of Fig. 1.
Fig. 3 be Fig. 2 B to figure (amplification).
Embodiment
As shown in Figure 1, a kind of automobile speed variator shift device, comprise axle 1, low speed gear needle roller 2, low speed gear 3, tooth cover 4, high gear needle roller 5, thrust plate 6, high gear 7, low speed gear 3 is placed on the axle by low speed gear needle roller 2, high gear 7 is placed on the axle 1 by high gear needle roller 5, tooth cover 4 usefulness internal splines are contained on the external splines of axle 1 can only do axial motion with axle, the axial motion of thrust plate 6 limiting gears is characterized in that: the soldered tooth and the high gear 7 of tooth cover 4, the soldered tooth of low speed gear 3 adopts the monocline surface chamfer (as Fig. 2, shown in 3).
The utility model tooth overlaps 4 drag-downs, and when the tooth cover moved toward low speed gear 3 directions, tooth overlapped 4 monocline face C and works, and drives low speed gear 3 rotations by axle 1, and low speed gear 3 is relative static with low speed gear needle roller 2; Tooth overlaps 4 shifts to a higher gear, and when the tooth cover moved toward high gear 7 directions, tooth overlapped 4 monocline face D and works, and drives high gear 7 rotations by axle 1, and high gear 7 is relative static with high gear needle roller 5.
The speed changer of existing band odd-side is because speed discrepancy is positive and negative constant, and engage a gear generally can adopt this structure with soldered tooth.
