Abstract
The invention discloses a kind of automobile gear shift operating rod, comprise upper rod section (1) and lower rod section (2), wherein, the bottom of upper rod section (1) is formed with the first sloping platform (3), by the first inclined-plane (5) transition between the lower end surface of the first sloping platform (3) and upper rod section (1), the second sloping platform (4) is formed on the top of lower rod section (2), by the second inclined-plane (6) transition between the upper-end surface of the second sloping platform (4) and lower rod section (2), by the first inclined-plane (5) and the second inclined-plane (6) snap fit between upper rod section (1) and lower rod section (2), male-female engagement rotation prevention structure is provided with between the first inclined-plane (5) and the second inclined-plane (6).The present invention, by the axial male-female engagement between upper rod section and lower rod section inclined-plane, improves the performance accuracy of anti-rotation ability between upper rod section and lower rod section and gearshift; And axial male-female engagement also can play the effect of guiding to upper and lower bar section assembling, improve precision and the speed of assembling.
Description
Technical field
The invention belongs to automobile technical field, specifically, the gear shift operating rod particularly on automobile.
Background technique
Existing automobile gear shift operating rod is made up of upper rod section and lower rod section, is formed with the first inclined-plane and the second inclined-plane respectively in the butt end of upper rod section and lower rod section, and upper rod section and lower rod section are by the first inclined-plane and the second inclined-plane snap fit.Said structure has the following disadvantages in installation and using process: first, automobile is in various shift process, operating handle needs to carry out operating to front, rear, left and right different direction, because upper rod section is connected circumferential spacing deficiency with the inclined-plane compression of lower rod section, relatively rotating of upper rod section and lower rod section can be caused, thus affect the precision of gear shift operation and handling; Secondly, owing to lacking axial installation guiding, in upper rod section and lower rod section inclined-plane abutting joint process, positional deviation can be produced, the effect of impact assembling.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can the automobile gear shift operating rod of effective anti-rotation.
Technological scheme of the present invention is as follows: a kind of automobile gear shift operating rod, comprise upper rod section (1) and lower rod section (2), wherein, the bottom of upper rod section (1) is formed with the first sloping platform (3), by the first inclined-plane (5) transition between this first sloping platform (3) and lower end surface of upper rod section (1), the second sloping platform (4) is formed on the top of described lower rod section (2), by the second inclined-plane (6) transition between this second sloping platform (4) and upper-end surface of lower rod section (2), by the first inclined-plane (5) and the second inclined-plane (6) snap fit between described upper rod section (1) and lower rod section (2), the rotation prevention structure of male-female engagement is provided with between described first inclined-plane (5) and the second inclined-plane (6).
Adopt above technological scheme, by adding concave-convex fit structure between first inclined-plane and the second inclined-plane of lower rod section of upper rod section, the fitting surface of upper rod section and lower rod section the is possessed function of anti-rotation, like this when carrying out automobile gear shift operation, position and the rotating deviation of upper and lower bar section are improved widely, make the performance accuracy of gearshift higher, gearshift better handling.
Protrude in the upper one of described first inclined-plane (5) and be formed with boss (7), described second inclined-plane (6) is formed the groove (8) matched with boss (7), and the boss (7) of described first inclined-plane (5) snaps onto in the groove (8) of the second inclined-plane (6).The cooperating structure of boss and groove is compact, fitting tight, can play better anti-rotation limit effect.
Described boss (7) distributes vertically, and boss (7) is positioned at the middle part of the first inclined-plane (5), and the lower end of boss (7) is concordant with the lower end surface of upper rod section (1), and upper end and first sloping platform (3) of boss (7) are connected as a single entity; Described groove (8) is positioned at the middle part of the second inclined-plane (6), and the upper end of groove (8) forms opening in the upper-end surface of upper rod section (2), and the lower end of groove (8) extends to the second sloping platform (4).Boss distributes vertically, when such upper rod section and lower rod section grafting are assembled, can play the effect of guiding, thus improves precision and the speed of assembling; And the anti-rotation effect of the boss of axis and groove fit is better.
The length of described boss (7) is less than the length of groove (8), and the width of boss (7) is consistent with the width of groove (8), is 2-4mm.The length of boss is less than the length of groove, just can boss be avoided long and interfere with the lower end of groove, and the width of boss and groove is 2-4mm, both can ensure structural strength, also can reduce the area taking inclined-plane.
Beneficial effect: the present invention is by the axial male-female engagement between upper rod section and lower rod section inclined-plane, the fitting surface of upper rod section and lower rod section the is possessed function of anti-rotation, like this when carrying out automobile gear shift operation, position and the rotating deviation of upper and lower bar section will improve greatly, make the performance accuracy of gearshift higher.Meanwhile, the axial male-female engagement between upper rod section and lower rod section inclined-plane, when the inclined-plane grafting of upper rod section and lower rod section is assembled, plays the effect of guiding, can improve precision and the speed of assembling.
