Abstract
Tripod moves universal joint, it is the parts of automotive transmission, with ball pin and pot shell, ball pin is along week provided with three axostylus axostyles uniformly arranged, the axial line of each axostylus axostyle is vertical with the axial line of ball pin respectively, respectively equipped with a ball on each axostylus axostyle, the inner ring surface of each ball is rotated with corresponding axostylus axostyle respectively to be connected, it is characterised in that：A ring set is respectively cased with each ball, the inner ring sphere of each ring set is slidably connected with the outer shroud sphere of corresponding ball, three grooves corresponding with three ring set difference are provided with described pot shell, the outer shroud face of cylinder of each ring set rolls with the cell wall of respective grooves both sides crimp respectively, and the high capacity of the tripod movement universal joint of the structure, wear resistance are strong, service life is long.
Description
Technical field
The utility model provides a kind of tripod movement universal joint, belongs to auto parts and components field.
Background technology
Existing tripod moves universal joint, and the cell wall of three groove both sides of its pot shell is the Dan Yuan matched with ball
Arc cell wall, to make, the ball in ball pin is turned round and axial stretching is flexible, is left between the cell wall and ball of groove both sides certain
Gap, because the outer ring surface of ball is spherical anchor ring, so being that point is contacted between ball and cell wall, bearing capacity is low, easy to wear, abrasion
Afterwards, the gap of ball and groove becomes big, will produce abnormal sound during work, it is necessary to change part, service life is short, many costs of component
Height, Customer Satisfaction rate is low.
The content of the invention
The purpose of this utility model is to provide that a kind of high capacity, abrasion resistance properties are good, service life length tripod
Mobile universal joint.
The technical solution of the utility model is：Tripod moves universal joint, with ball pin (4) and pot shell (1), ball pin edge
Week, the axial line (10) of each axostylus axostyle was vertical with the axial line (9) of ball pin respectively, each provided with three axostylus axostyles (5) uniformly arranged
Respectively equipped with a ball (7) on axostylus axostyle, the inner ring surface of each ball is rotated with corresponding axostylus axostyle respectively to be connected, it is characterised in that：Often
A ring set (8) is respectively cased with individual ball, the inner ring sphere of each ring set is slidably connected with the outer shroud sphere of corresponding ball, described
Be provided with three grooves (2) corresponding with three ring set difference in pot shell, the outer shroud face of cylinder (11) of each ring set respectively with corresponding ditch
The cell wall (3) of groove both sides rolls crimping.
The utility model has the advantages that：Increase ring set between ball and the groove of pot shell, the outer shroud face of cylinder of ring set with
It is in the linearly connected of roller between the cell wall of groove, makes its stress more reasonable, holding for tripod movement universal joint can be improved
Power is carried, makes it have that abrasion resistance properties are good, physical life length advantage；The outer shroud sphere activity of the inner ring sphere and ball of ring set
Be connected, its sliding contact surface is an Internal Spherical Surface and a spherical outside surface, during motion can in any angle rotary oscillation,
The deflectable characteristic of sphere connection is made it have, setting angle is not only increased, moreover it is possible to reduces axially gradually Cheng Li, and lift NVH
Performance, the tripod of the application is moved universal joint also has the advantages that low noise, low vibration, ride comfort are good.

Embodiment
Tripod moves universal joint, with ball pin 4 and pot shell 1, and ball pin is provided with three axostylus axostyles 5 uniformly arranged along week,
The axial line 10 of each axostylus axostyle is vertical with the axial line 9 of ball pin respectively, respectively equipped with ball 7 on each axostylus axostyle, each ball it is interior
Anchor ring rotates with corresponding axostylus axostyle connect respectively, is respectively cased with a ring set 8 on each ball, the inner ring sphere of each ring set with it is corresponding
The outer shroud sphere of ball is slidably connected, and three grooves 2 corresponding with three ring set difference are provided with described pot shell, each ring set
The outer shroud face of cylinder 11 rolls with the cell wall 3 of respective grooves both sides crimp respectively, and the rotating direction 15 of ring set is the longitudinal direction along groove
Direction.The inner ring surface of the ball is rotated with described axostylus axostyle by needle roller 6 and is connected, wherein, between needle roller and ball circumferentially
Rolling pair each other, sliding pair each other vertically between needle roller and ball, rolling pair each other vertically between needle roller and axostylus axostyle, so that
Ball is set to be rotated motion around axostylus axostyle.Described ring set on ball, can make ring set is spacing to be done on ball by pressing sleeve
The slip of certain angle is swung, i.e., the axial line 12 of ball is swung circumferentially around the axial line 13 of ring set, so as to add
Setting angle, assembling semiaxis 14 is time saving and energy saving.
