CN201494504U - Novel vehicle gearbox beam - Google Patents

Abstract

The utility model discloses a novel vehicle gearbox beam, which is characterized in that a layer of reinforcd templete (2) is arranged on a gearbox beam (1); and the reinforcd templete (2) is fixedly connected with the gearbox beam (1). The utility model enhances the firmness degree and the tensile capacity of the beam to certain extent, and prolongs the service life of the gearbox beam.

Description

A kind of new vehicle change speed gear box crossbeam

Technical field

The utility model relates to a kind of vehicular field, more particularly, relates to a kind of new vehicle change speed gear box crossbeam, can solve because change speed gear box beam deformation or the fracture that road injustice or sudden stop cause.

Background technology

Change speed gear box crossbeam in the vehicle is one of parts of paramount importance, performance with car is closely bound up, in use there is following defective in existing change speed gear box crossbeam: when car travels on the road of road injustice or during sudden stop for a long time, the change speed gear box crossbeam will bear certain flexure stress, and change speed gear box crossbeam of long duration can deform or rupture.

Summary of the invention

The utility model purpose provides a kind of new vehicle change speed gear box crossbeam, can strengthen the firm degree of crossbeam itself and bear ability, prolongs the service life of change speed gear box crossbeam.

For solving the problems of the technologies described above, the utility model by the following technical solutions, a kind of new vehicle change speed gear box crossbeam, described change speed gear box crossbeam are provided with one deck and strengthen matrix, described reinforcement matrix is fixedly connected with described change speed gear box crossbeam.

By rivet, four jiaos of described reinforcement matrixs are fixing with described change speed gear box crossbeam welding with described change speed gear box crossbeam for described reinforcement matrix.

Described reinforcement matrix is identical with described change speed gear box beam shape.

The utility model has following beneficial effect with respect to prior art:

Be fixed with the reinforcement matrix on the change speed gear box crossbeam, improved the firm degree of change speed gear box crossbeam self to a certain extent and born ability, prolonged the service life of change speed gear box crossbeam, be generally 3-4 times of existing common change speed gear box crossbeam.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described:

Fig. 1 is the utility model block diagram;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is the lateral plan of Fig. 2.

Among the figure: 1. change speed gear box crossbeam 2. is strengthened matrix 3. rivets.

The specific embodiment

By Fig. 1-3 as can be seen, be fixed with on change speed gear box crossbeam 1 and strengthen matrix 2, the shape of strengthening matrix 2 is the same with the shape of change speed gear box crossbeam 1, and its size is slightly less than the size of change speed gear box crossbeam 1.At first produce a reinforcement matrix 2 that is close with change speed gear box crossbeam 1 shape by the metal work grinding tool, again this is strengthened matrix 2 and make itself and change speed gear box crossbeam 1 comprehensive closed contact by bigger pressure, at this moment, four angles of strengthening matrix 2 just in time enter into the groove at 1 four angles of change speed gear box crossbeam, to strengthen matrix 2 by metal rivet 3 is again fixed with the marginal portion of change speed gear box crossbeam 1 junction, change speed gear box crossbeam 1 is fixed by welding manner with the part of strengthening matrix 2 four angular contacts, like this, change speed gear box crossbeam 1 is with strengthening combining of matrix 2 close and firm, strengthen the firm degree of change speed gear box crossbeam 1 itself greatly and born ability, thereby prolonged the service life of change speed gear box crossbeam 1.

The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims (3)

1. a new vehicle change speed gear box crossbeam is characterized in that, described change speed gear box crossbeam (1) is provided with one deck and strengthens matrix (2), and described reinforcement matrix (2) is fixedly connected with described change speed gear box crossbeam (1).

2. vehicle gear box crossbeam according to claim 1 is characterized in that, by rivet (3) riveted joint, (2) four jiaos of described reinforcement matrixs are fixing with described change speed gear box crossbeam (1) welding with described change speed gear box crossbeam (1) for described reinforcement matrix (2).

3. vehicle gear box crossbeam according to claim 1 and 2 is characterized in that, described reinforcement matrix (2) is identical with described change speed gear box crossbeam (1) shape.
