Abstract
The utility model belongs to automotive transmission class, and specifically a kind of gearshift self-locking mechanism of low surface friction drag, comprises shift rod, self-locking grooves, has self-locking steel ball and self-locking spring, it is characterized in that in self-locking grooves: between self-locking steel ball and self-locking spring, be provided with antifriction pad.Antifriction pad of the present utility model is nylon pad, Cuprum alloy pad or aluminum alloy pad etc.During utility model works, shift rod moves axially and drives self-locking steel ball to climb, and antifriction pad promotes self-locking spring, and self-locking spring is compressed; When shift rod continues to move axially, self-locking spring decrement discharges, and antifriction pad promotes self-locking steel ball and falls into self-locking grooves, realizes gearshift.The utility model whole shift process, is rolling friction between self-locking steel ball and shift rod at self-locking steel ball and self-locking spring, and surface friction drag is little, gearshift good hand touch.
Description
Technical field
The utility model belongs to automotive transmission class, specifically a kind of gearshift self-locking mechanism of low surface friction drag.
Background technique
Gearshift performance is the important quality evaluation index of manual transmission, and the quality of gearshift feel directly affects the travelling comfort of driving.Domestic used automotive transmission at present, its gearshift self-locking mechanism is made up of shift rod self-locking grooves or scope neutral gear groove, self-locking steel ball and self-locking spring usually, its shortcoming is: during gearshift, self-locking steel ball rolls with not relative between self-locking spring, self-locking steel ball and shift rod slide, surface friction drag is large, and gearshift feel is poor.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides that a kind of structure is simple, the gearshift self-locking mechanism of self-locking steel ball energy Free-rolling, surface friction drag is little, cost is low low surface friction drag.
The technical solution of the utility model is as follows:
A gearshift self-locking mechanism for low surface friction drag, comprises shift rod, self-locking grooves, has self-locking steel ball and self-locking spring, it is characterized in that in self-locking grooves: between self-locking steel ball and self-locking spring, be provided with antifriction pad.
Antifriction pad of the present utility model is nylon pad, Cuprum alloy pad or aluminum alloy pad etc.
During utility model works, shift rod moves axially and drives self-locking steel ball to climb, and antifriction pad promotes self-locking spring, and self-locking spring is compressed; When shift rod continues to move axially, self-locking spring decrement discharges, and antifriction pad promotes self-locking steel ball and falls into self-locking grooves, realizes gearshift.The utility model whole shift process, is rolling friction between self-locking steel ball and shift rod at self-locking steel ball and self-locking spring, and surface friction drag is little, gearshift good hand touch.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of gearshift self-locking mechanism of low surface friction drag, comprises shift rod 4, self-locking grooves, has self-locking steel ball 3 and self-locking spring 1, it is characterized in that: between self-locking steel ball 3 and self-locking spring 1, be provided with antifriction pad 2 in self-locking grooves.
During utility model works, shift rod 4 moves axially and drives self-locking steel ball 3 to climb, and antifriction pad 2 promotes self-locking spring 1, and self-locking spring 1 is compressed; When shift rod 4 continues to move axially, self-locking spring 1 decrement discharges, and antifriction pad 2 promotes self-locking steel ball 3 and falls into self-locking grooves, realizes gearshift.The utility model whole shift process, is rolling friction between self-locking steel ball 3 and shift rod 4 at self-locking steel ball 3 and self-locking spring 1, and surface friction drag is little, gearshift good hand touch.
