Abstract
The utility model discloses a wear resistant type shifting fork used for a motor vehicle gearbox, which comprises a shifting fork body (1), wherein a nylon sheath (3) is arranged on a pin part (2) of the shifting fork body (1). According to the wear resistant type shifting fork, the pin part of the shifting fork body is stably combined with the nylon sheath, a gear of the gearbox is shifted by the shifting fork by utilizing the nylon sheath on the pin part, thereby reducing resistance and wear, increasing wearability and greatly reducing loss caused by collision and friction between two parts, and the service lives of the two parts are prolonged. The wear resistant type shifting fork is especially suitable for a reverse shifting fork.
Description
Technical field
The utility model relates to a kind of motor vehicle gearbox field, specifically relates to the shift fork that a kind of motor vehicle gearbox is used.
Background technique
At present, the shift fork that motor vehicle gearbox is used is to be used for stirring the gear in the gearbox, and shift fork and gear belong to rigid contact of fork face of steel to steel between the two, and shift fork quick abrasion, loss are big, have shortened working life greatly.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of wear-resisting formula shift fork slow, that loss is few that weares and teares.
For realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of wear-resisting formula shift fork, comprise the shift fork body, and in the foot of said shift fork body, nylon sheath wire is housed.
Have groove on the foot surface of said shift fork body, said nylon sheath wire internal layer has the convexity that matches and install with this groove.
Through adopting technique scheme; The foot of shift fork body combines with nylon sheath wire firmly, and shift fork utilizes the nylon sheath wire in its foot to stir gearbox gear, thereby has reduced resistance; Wearing and tearing have been reduced; Increase wear resistance, greatly alleviated collision and the loss that friction causes between both parts, all obtained prolongation both working life.Be specially adapted to reverse shift fork (three fourth gear shift forks).
Description of drawings
Fig. 1 is the structural representation of the wear-resisting formula shift fork of the utility model.
Fig. 2 is the E-E 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, the utility model is applied to the wear-resisting formula shift fork of motor vehicle gearbox, comprises shift fork body 1, and (through extrusion process) is equipped with nylon sheath wire 3 in the foot 2 of said shift fork body 1.
Have groove 4 (some) on foot 2 surfaces of said shift fork body 1, said nylon sheath wire 3 internal layers have the convexity 5 that matches and install with this groove 4.Thereby the foot of shift fork body is combined firmly with nylon sheath wire.
Wherein, the material of nylon sheath wire 3 can be the PA66 Reinforced Nylon, and elasticity is good, and is not easy to wear.
Claims (2)
1. a wear-resisting formula shift fork comprises shift fork body (1), it is characterized in that: in the foot (2) of said shift fork body (1), nylon sheath wire (3) is housed.
2. wear-resisting formula shift fork according to claim 1 is characterized in that: have groove (4) on foot (2) surface of said shift fork body (1), said nylon sheath wire (3) internal layer has the convexity (5) that matches and install with this groove (4).
