Abstract

The utility model discloses a damping structure for a gear shifting cable of a gear box, the gear shifting cable is permanently connected with a bracket, the bracket is fixed on the gear box through a first bolt, and the assort position of the first bolt and the bracket is sleeved with a metal lining, the outer surface of which is also sleeved with a rubber bushing. In the utility model, the metal lining and the rubber bushing are added at the connection part between the bracket used for fixing the gear shifting cable and the gear box, thereby realizing the isolation of a vibration source and the gear shifting cable, and effectively reducing the shaking of the gear shifting cable and the gear shifting ball handle of the gear box. The additional arrangement of the damping structure between the gear shifting cable and a gear pull-out shank can further reduce the shaking of the gear shifting cable and the gear shifting handle. Compared with the prior art, the damping structure has the advantages of simple structure, flexible application, wide use and low cost.

Description

The vibration damping structure of gearbox shifting drag-line

Technical field

The utility model relates to the shift control mechanism of gearbox, particularly relates to a kind of vibration damping structure that is used to alleviate the shake of gearshift drag-line.

Background technique

Automobile because the vibration of the not gentle engine operation on road surface, makes that connecting the gearbox gear pulls out the gearshift drag-line of bar and have to a certain degree shake in the process of moving.This shake is delivered to shift handle along the gearbox shifting Effector always, makes the operator cabin shift handle in shake, has had a strong impact on driver's shift feel.

At present, in the gearbox shifting operating mechanism or do not have vibration reducing measure, influence driver's shift feel; Though in the gearbox shifting device vibration reducing measure is arranged, the vibration damping degree is not enough, and perhaps cost increases.

The model utility content

The technical problems to be solved in the utility model provides the better gearbox shifting pulling cable damping of a kind of effectiveness in vibration suppression structure, under the prerequisite that satisfies gearshift performance and shift feel, reduces the shake of shift handle.

In order to solve the problems of the technologies described above, the technological scheme that the utility model is taked is: a kind of vibration damping structure of gearbox shifting drag-line, described gearshift drag-line is fixedlyed connected with a support, described support is bolted on the gearbox by first, the matching part of described first bolt and support is with a metal lining, and the outside of metal lining also is with a rubber bushing.

Further, an end of described gearshift drag-line is also pulled out bar by second bolt and gear and is connected, and the matching part that described second bolt and gear are pulled out bar also is with a metal lining, and the outside of metal lining also is with a rubber bushing.

The utility model has increased metal lining and rubber bushing at the support and the connection part between the gearbox of fixing gearshift drag-line, thereby realizes vibration source and gearshift drag-line are isolated, and has reduced the shake of a gearbox shifting drag-line and a gearshift ring handle effectively.Pull out at gearshift drag-line and gear and to set up the shake that this vibration damping structure can further reduce shift gears drag-line and shift handle between the bar.Compared with prior art, simple in structure, the applying flexible of the utility model, use are extensive, with low cost.

Description of drawings

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

Fig. 1 is the annexation schematic representation of gearshift drag-line and gearbox.

Fig. 2 is the annexation schematic representation that gearshift drag-line and support, gear pulled out bar in the utility model.

Fig. 3 is the vibration damping structure schematic representation of the support and the first bolt joint.

Fig. 4 is the vibration damping structure schematic representation that gear is pulled out the bar and the second bolt joint.

Wherein: 1 second bolt, 2 gears are pulled out bar, 3 gearshift drag-lines, 5 first bolts, 6 supports, 7 metal linings, 8 rubber bushings, the boss on 9 gearboxes.

Embodiment

As shown in Figure 1 and Figure 2, gearshift drag-line 3 is fixedlyed connected with a support 6, and support 6 is fixed on the boss 9 on the gearbox by first bolt 5, and an end of the drag-line 3 of shifting gears is also pulled out bar 2 by second bolt 1 and gear and is connected.

As shown in Figure 3, first bolt 5 is with a metal lining 7 with the matching part of support 6, the outside of metal lining 7 also is with a rubber bushing 8, rubber bushing 8 inlay cards are in the bolt hole of support 6, rubber bushing 8 is provided with flange up and down, the edge of support 6 bolts hole is encased, thereby support 6 is not directly contacted with first bolt 5, gearbox, the vibration that gearbox produced is just isolated effectively like this, and the vibration that process metal lining 7 and rubber bushing 8 pass to support 6 and gearshift drag-line 3 has significantly reduced.

As shown in Figure 4, similar with said structure, second bolt 1 also is with a metal lining 7 with the matching part that gear is pulled out bar 2, and the outside of metal lining 7 also is with a rubber bushing 8.Like this, pull out after bar 2, rubber bushing 8, metal lining 7 and second bolt 1 pass to gearshift drag-line 3 through gear successively, just significantly reduced from the vibration of gearbox.

The utility model all is provided with vibration damping structure at several connection parts of gearshift drag-line and gearbox, thereby vibration source and gearshift drag-line are isolated, and has reduced the shake of gearshift drag-line and gearshift ball handle effectively.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model is not subjected to the restriction of above-mentioned embodiment; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
