Abstract
The utility model relates to a gear shifting device for an automotive transmission, and belongs to automobile manufacturingfield. The gear shifting device comprises a shaft, a gear, a cone, a gear sleeve, a synchronous ring, a pushing block, a spring of the pushing block, and a toothholder, wherein, the gear is sleeved on the shaft loosely through a bearing; and the gear sleeve is in contact with the synchronous ring and the cone through inclined planes and synchronous gear shifting is realized. The gear shifting device is characterized in that joint teeth of the cone are jointed with the gear sleeve by adopting single inclined surface chamfer; and the cone is in electron beam welding with the gear through. The gear shifting of the gear shifting device is realized through a synchronizer; in the jointing of the cone and the gear sleeve, the cone is jointed by adopting the structure of single inclined surface, which enables the jointing to be smoother, and the impact force in the synchronization to be smaller; and besides, by adopting the single inclined surface jointing, the intensity and the friction contact area of the cone are increased, and the service life of the synchronizer is prolonged.
Description
Technical field
The utility model belongs to the automobile making class, specifically is a kind of gearshift of automotive transmission.
Background technique
At present, shifting vehicle gearbox adopts synchronizer to finish substantially, and existing synchronizer gear sleeve and cone soldered tooth engagement Leading end chamfer generally adopt the double inclined plane structure of symmetry, engage according to the different inclined-plane of the positive and negative use of speed discrepancy when putting into gear.Because present automotive transmission is all to many retainingizations development, synchronizer develops to many conical surfaces, and the speed changer speed discrepancy is constant, and existing double inclined plane structure is succinct inadequately, processed complex, and operational safety is not high.
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, make simpler, uses more reliable, engagement more smoothly the synchromesh cone soldered tooth adopt the gearshift of the automotive transmission of monocline surface chamfer joint.
The technical solution of the utility model is as follows:
A kind of gearshift of automotive transmission, comprise axle, gear, cone, tooth cover, synchronizing ring, pushing block, pushing block spring, toothholder, gear is placed on the axle by bearing, the tooth cover contacts by the inclined-plane with synchronizing ring, cone and realizes same step gear shifting, it is characterized in that: the soldered tooth of cone adopts the monocline surface chamfer to engage with the tooth cover.
The utility model cone and gear are bonded together by electron beam welding.
The utility model gearshift is realized gearshift by synchronizer, in the engaging process of cone and tooth cover, cone adopts monocline face structure to engage, make joint more smooth and easy, impact force is little in the synchronizing process, simultaneously, because the monocline face engages, increase the intensity and the rubbing contact area of cone, prolonged the working life of synchronizer.

Fig. 2 is A-A figure.
Fig. 3 is that cone B is to figure (amplification).
Embodiment
As shown in Figure 1, 2, 3, a kind of gearshift of automotive transmission, comprise axle 1, low gear gear 3, cone 4, synchronizing ring 5, tooth cover 6, pushing block 7, pushing block spring 8, toothholder 9, high gear gear 10, gear is enclosed within on the axle 1 by bearing 2 skies, it is characterized in that: cone 4 soldered tooths adopt the monocline surface chamfer, cone 4 engages the flank of tooth by the monocline surface chamfer with the tooth cover and engages, and final the realization shifted gears.
The utility model cone 4 and low gear gear 3, high gear gear 10 are bonded together by electron beam welding.
Bearing 2 of the present utility model is a needle bearing.
