Description

Selector shift flexible shaft for vehicle

technical field

The utility model relates to an automobile gear selection and shifting device, in particular to a vehicle gear selection and shifting flexible shaft with a damping effect.

Background technique

With the development of the economy and the improvement of people's living standards, automobiles have become one of the indispensable means of transportation for people, and the gear selection shaft on the automobile is one of the parts that must be used when the automobile is selecting gears or shifting gears. The existing gear selection shaft is directly installed on the gear selection rocker arm or the gear shift rocker arm of the transmission to realize the gear selection or gear shift function. In this way, when the car is running on an uneven road or a mountain road, the car will bump , When the driver selects gears like this, because the gear selection shaft is also unstable with the bumps of the car, the operation of the transmission will produce relatively large vibrations and noises, and it is also uncomfortable to drive.

As mentioned above, there are following deficiencies in the prior art: when the gear is selected and shifted, the transmission will produce relatively large vibration and noise, and the driving is uncomfortable.

Contents of the invention

The utility model solves the problems in the prior art that the transmission generates relatively large vibration and noise when selecting and shifting gears, and the problem of uncomfortable driving is provided, and provides a flexible shaft for selecting and shifting a vehicle with a damping effect.

The above-mentioned technical purpose of the utility model is mainly solved by the following technical solutions: a flexible shaft for shifting gears for vehicles, including a flexible shaft for shifting gears and a flexible shaft for shifting gears adapted to it, characterized in that the shifting soft shaft A shock absorber is connected to the lower end of the shaft, and the shock absorber includes an earring rod and an elastic bush, and the elastic bush is placed in the earring rod. The gear shift flexible shaft is installed on the gear shift rocker arm of the transmission to realize the gear shift function; the gear selection flexible shaft is installed on the gear selection rocker arm of the transmission to realize the gear selection function; the material of the elastic bush can be plastic or It is an elastic body such as rubber. Due to the setting of the elastic bush, the driver can reduce the vibration and noise generated by the transmission when selecting and shifting gears, and improve the driving comfort.

Preferably, the earring rod includes an annular collar and a straight rod connected thereto. The annular ferrule is used for interference fit with the elastic bushing inside, and the straight rod is used for matching and connecting the flexible shift shaft assembly.

Preferably, several annular holes are provided in the elastic bush, and the elastic bush is fixedly connected in the annular collar. The arrangement of the annular hole makes the inner part of the elastic bushing a hollow structure, which has a buffering effect, so that when the driver selects gears, the vibration and noise generated by the transmission can be reduced, and the driving comfort is improved.

Preferably, the elastic bushing is interference-fitted to connect with the annular ring. In this way, the connection between the two is stable and the safety is improved.

The utility model is ingeniously conceived, and compared with the prior art, it has the following beneficial effects through the setting of the shock absorbing device:

Reduce the vibration and noise generated by the transmission when the driver selects gears, and improve the driving comfort.

FIG. 2 is an enlarged structural schematic diagram of part A in FIG. 1 .

Detailed ways

The technical solutions of the present utility model will be further described below through the embodiments and in conjunction with the accompanying drawings.

Example 1. See Fig. 1 and Fig. 2, this example is a kind of flexible shaft for selecting and shifting for a vehicle, including a flexible shaft for shifting 1 and a flexible shaft for selecting a gear 2 adapted to it, and the flexible shaft for shifting 1 is installed on the shifting rocker arm of the transmission to realize the shift function; the gear selection flexible shaft 2 is installed on the gear selection rocker arm of the transmission to realize the gear selection function; the lower end of the shift flexible shaft 1 is connected with a shock absorber 3, and the shock absorber 3 includes An earring rod 4 and an elastic bush 5, the elastic bush 5 is a rubber bush.

Wherein, the earring rod 4 includes an annular ferrule 6 and a straight rod 7 connected thereto; the elastic bush 5 is provided with two annular holes 8, and the elastic bush 5 is interference-fitted in the annular ferrule 6 . When the driver selects gears, the elastic bush 5 has a hollow structure due to the annular hole 8, which can reduce the vibration and noise generated by the transmission and improve driving comfort.

It is obvious to those skilled in the art that the present utility model can be changed in many ways, and such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art are intended to be included within the scope of this claim.
