Abstract
The utility model discloses a tripod assembly of a tripod universal joint, comprising a spider, three pin shafts in 120 degrees of mutual distance on the spider, ball rings sleeved on the pin shafts, a ball race between the ball ring and the pin shaft and needle rollers in parallel in the ball race and is characterized in that a ring collar fitted with the aperture of the ball race is arranged outside the needle rollers, an elastic collar is disposed outside the ring collar and the elastic collar is fixed on the pin shaft and is contacted and fitted with a surface of the ring collar. The utility model has the advantages that the point contact surface of the needle roller collar and the elastic collar is modified into a surface contact, which promotes the bearing capacity of the axial force of the needle roller of the needle roller collar, so that the needle roller can be fixed more stably and the service life can be prolonged, and moreover, a circular bead is arranged on the ball ring, which promote the requirement of the slippage of the ball ring to meet the tilt angle of the spider.
Description
Technical field
The utility model relates to three ball pin assemblies of a kind of tripod constant-velocity universal joint (TJ type constant velocity universal joint).
Background technique
Three ball pin assemblies are core components of tripod constant-velocity universal joint, its major function is to transmit engine mission by the torsion of mobile terminal to wheel, three traditional ball pin assembly structures (as shown in Figure 1) comprise spider 1, be installed on three bearing pins 2 of 120 ° of spider 1 and spaces, the described bearing pin 2 outer balls 3 that are set with, between this ball 3 and the bearing pin 2 raceway is set, be arranged with needle roller 4 in the described raceway side by side in parallel, the outside of described needle roller 4 is sealed to prevent that needle roller 4 from dropping with needle roller back-up ring 5, at right angles upwards the flange setting is done in bending and its edge section to this needle roller back-up ring 5, its purpose is to improve the slippage of ball 3 and carry out spacing to ball 3, the outer end of the needle roller back-up ring that described bearing pin 2 is relative also is provided with axial trough, be provided with the circlip 6 that needle roller back-up ring 5 is fixed in this axial trough, this circlip 6 is circular steel wire for the cross section.When requiring three ball pin assembly transferring power on the engineering, satisfy certain pivot angle and move axially flexible, no clamping stagnation, noiseless, require bigger pivot angle then to necessarily require ball 3 to have bigger slippage, therefore the right angle of needle roller back-up ring 5 upwards bending just than higher, it is very high to make that the flange at needle roller back-up ring 5 edges just is set up, occurring needle roller back-up ring 5 easily contacts with shell 7 inwalls outside the three ball pins when three ball pins rotate, interfere, make 5 distortion of needle roller back-up ring, influence the working life of whole three ball pin assemblies thereby make needle roller 4 and ball 3 come off, but also can produce very big noise, influence environment.In addition owing to circlip 6 is that the cross section is circular steel wire, needle roller back-up ring and this circlip 6 be contact stressed, therefore needle roller back-up ring 5 comes off from circlip 6 easily, and the cross section also makes greatly reduce the working life of whole three ball pin assemblies for circular circlip 6 itself also skids off in its axial trough when three ball pin assemblies are worked easily.
The model utility content
The purpose of this utility model is in order to overcome the shortcomings and deficiencies of prior art, and a kind of long service life is provided, and the pivot angle amplitude is big, three ball pin assemblies of the three ball pin style universal joint that noise is little.
For achieving the above object, the technical solution of the utility model is a kind of three ball pin assemblies of three ball pin style universal joint, comprise spider, be installed on three bearing pins of 120 ° of spider and spaces, be set with ball on the described bearing pin, be provided with raceway between this ball and the bearing pin, be arranged with needle roller in the described raceway side by side in parallel, it is characterized in that: the arranged outside of described needle roller has the adaptive annular retaining ring in raceway aperture, the described annular retaining ring outside is by the circlip shutoff, this circlip fixedly sleeved on the bearing pin and and annular retaining ring between be the setting of face contact matching.
Described circlip outer edge part further is set is provided with at least one projection, described ball is provided with the shoulder adaptive with projection.
Further setting is that the face contact matching between described circlip and the annular retaining ring is set to the staggered chimeric setting of male and fomale(M﹠F).The further setting of this setting is that described male and fomale(M﹠F) is a corrugated.
Another kind of setting is that the face contact matching between described circlip and the annular retaining ring is set to plane close neighbour's butt setting.The further setting of this setting is that the cross section of described circlip and annular retaining ring is for being rectangular, the quantity of described projection is that two and the two are symmetrical arranged, the cross section of this projection be square and cross-pressure on annular retaining ring and extend in the shoulder and constitute spacing the cooperation with ball.
So advantage of the present utility model contacts with the point of circlip and is the face contact changing original needle roller back-up ring, improved the ability that the needle roller back-up ring bears the axial force of needle roller, make fixing more firm of needle roller, improved working life, ball is provided with shoulder in addition, and the slippage that has improved ball has satisfied the pivot angle requirement of three ball pin work.
Below in conjunction with Figure of description the utility model is done further introduction.
