Abstract
The utility model discloses a gear shifting and selecting shaft which is applied to a transmission of a motor vehicle. The gear shifting and selecting shaft comprises a shaft body (1), and a hard chromium layer (2) is arranged on the surface of the shaft body (1). According to the utility model, the hard chromium layer with good wear resistance and hardness covers the surface of the shaft body of the gear shifting and selecting shaft, the surface roughness is increased, thus greatly relieving the loss caused by collision and friction among internal parts in the gear shifting and selecting mechanism of the transmission of the motor vehicel, prolonging the service lives of the parts, and also ensuring the safety performance.
Description
Technical field
The utility model relates to a kind of motor vehicle gearbox field, and what specifically relate to use in a kind of motor vehicle gearbox changes the block selecting axle.
Background technique
At present, be applied in the motor vehicle gearbox to shift gears, the surface roughness of changing the block selecting axle of block selecting mechanism is not enough, its wear resistance, hardness are all relatively poor, thereby have shortened its working life.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of can increase its surface roughness, and its wear resistance, hardness are all good changes the block selecting axle.
For realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of block selecting axle that changes, comprise axis body, and have hard chromium layers on the surface of said axis body.
Through adopting technique scheme; The all good hard chromium layers of wear resistance, hardness owing to change the axis body surface coverage of block selecting axle; Thereby increased its surface roughness; Greatly alleviated the loss that collision and friction between the in-house part of gearshift, block selecting of motor vehicle gearbox cause, all obtained prolongation the working life of its part, and Safety performance also is guaranteed.
Description of drawings
Fig. 1 changes the structural representation of block selecting axle for the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and mode of execution the utility model is done further to describe explanation.
Referring to Fig. 1, Fig. 2, what the utility model was applied to motor vehicle gearbox changes the block selecting axle, comprises axis body 1, has hard chromium layers 2 (through Hard Chromium Plating Technology) on the surface of said axis body 1.The surface coverage that is said axis body 1 has hard chromium layers 2.
Claims (1)
1. one kind is changed the block selecting axle, comprises axis body (1), it is characterized in that: have hard chromium layers (2) on the surface of said axis body (1).
