Abstract

The utility model relates to the technical field of intermediate rings, in particular to an intermediate ring of an automobile synchronizer, which comprises an intermediate ring and protruding teeth. The protruding teeth is arranged on the intermediate ring and manufactured by using a molding knife, and an R corner is formed between the protruding teeth and the intermediate ring. The intermediate ring of the automobile synchronizer adopts the molding knife to manufacture six protruding teeth, enables the diameter of all protruding teeth to keep identical, enables the root of each protruding tooth to form the R corner for transition due to the fact that the molding knife has the R corner, reduces stress concentration of the roots, simultaneously improves location degree of the six protruding teeth, eliminates breakage problems of the protruding tooth from all sides, and improves reliability of products.

Description

The automobile synchronizer central ring

Technical field

The utility model relates to the central ring technical field, especially a kind of automobile synchronizer central ring.

Background technique

The position of the relative inner conical surface of a plurality of double wedges of original automobile central ring is spent greatly; Cause in double wedge and the gear hole contact process that matches, the unbalance stress of each double wedge causes indivedual double wedges stressed excessive and rupture easily; The root of tooth is a wedge angle simultaneously; Cause stress to concentrate, double wedge is fracture easily also, and whole synchronizer was lost efficacy.

The model utility content

In order to overcome the deficiency of existing double wedge discontinuity, the utility model provides a kind of automobile synchronizer central ring.

The utility model solves the technological scheme that its technical problem adopted: a kind of automobile synchronizer central ring, comprise central ring and double wedge, and said central ring is provided with double wedge, and said double wedge adopts the moulding cutter to process, and forms the R angle between said double wedge and the central ring.

The beneficial effect of the utility model is that this automobile synchronizer central ring adopts the moulding cutter to process a plurality of double wedges, makes the diameter of each tooth keep unified; And because the moulding cutter has the R angle; The root of each double wedge just forms the transition of R angle, and the stress that has reduced root is concentrated, and has improved the position degree of a plurality of teeth simultaneously; Eliminate the breakage problem of double wedge from every side, improved reliability of products.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is that the utility model double wedge is connected schematic representation with central ring.

Among the figure 1, central ring, 2, double wedge, 3, the R angle.

Embodiment

Like Fig. 1 is the structural representation of the utility model, and a kind of automobile synchronizer central ring comprises central ring 1 and double wedge 2, and said central ring 1 is provided with double wedge 2, and said double wedge 2 adopts the moulding cutter to process, and forms R angle 3 between said double wedge 2 and the central ring 1.

The double wedge 2 of this automobile synchronizer central ring adopts the moulding cutter to process; The size of each double wedge 2 that has so just guaranteed to process is consistent, and because the moulding cutter has the R angle, the root of each double wedge 2 just forms 3 transition of R angle; The stress that has reduced root is concentrated; Improve the position degree of a plurality of double wedges 2 simultaneously, eliminated the breakage problem of double wedge 2 from every side, improved reliability of products.

Claims

1. automobile synchronizer central ring; Comprise central ring (1) and double wedge (2), said central ring (1) is provided with double wedge (2), it is characterized in that; Said double wedge (2) adopts the moulding cutter to process, and forms R angle (3) between said double wedge (2) and the central ring (1).
