Curved surfaces, the curved surfaces of two rolling rings and the touching of corresponding sliding slot side connect, the curved surfaces of the rolling ring in the same sliding slot
Also mutually touching connects, and two end faces other than the curved surfaces of rolling ring are respectively between the respective surfaces of both three pin shaft forks, three ball pins
With gap.
The utility model, the cooperation between sliding slot and the corresponding curved surfaces of rolling ring have the function of positioning, further cooperation rolling
Two end faces other than the curved surfaces of ring are respectively with the structure in gap between the respective surfaces of both three pin shaft forks, three ball pins
Feature, so that sliding friction is less prone in three pin shaft forks and three ball pin connection structures, to be less prone to serious abrasion
Problem, while 5% or more the weight saving of tripod universal joint assembly can be made, meet the light-weighted requirement of industry, this is also advantageous
In the running cost of reduction automobile, therefore all there is good influence on the maintenance of automobile and use cost on the whole.Especially
It is unique fit structure of the arcuate flanks of two sliding slots of sliding slot and the curved surfaces of rolling ring, is easily guaranteed that the arc of rolling ring
Two end faces other than surface have gap between the respective surfaces of both three pin shaft forks, three ball pins respectively.Therefore, this is practical new
Type is a kind of very preferential tripod universal joint assembly.
Preferably, the foot axis mounting surface is a flat surface.This preferred embodiment, structure is simple, and processing and manufacturing is easy, processing
Manufacturing cost is low.
Preferably, the slot bottom of sliding slot is arc cylinder.Further preferably arc-shaped cylinder.This preferred embodiment, structure
Rationally, processing and manufacturing is easy.
Preferably, end face of the foot axis far from three ball pins is arcwall face.This preferred embodiment, structurally reasonable, processing and manufacturing is held
Easily.
Preferably, further including having clip and washer；Foot axis stretches out rolling ring, and the part that foot axis stretches out rolling ring is equipped with a ring
Slot, clip are mounted on annular groove, and washer is located between clip and the respective end of rolling ring.This preferred embodiment first installs rolling ring
On corresponding foot axis, then clip and washer are set up, then again three ball pins and foot shaft assembly for installing rolling ring, clip and washer
It is installed on three pin shaft forks, installation speed block, quality are high.
Preferably, being equipped with copper sheathing between foot axis and rolling ring.This preferred embodiment, preceding not finding, can further decrease phase
The friction of motion resistance answered improves the advance of three pin shaft forks and three ball pin connection structures.
In conclusion the beneficial effects of the utility model are: reasonable integral structure, can make tripod universal joint assembly
5% or more weight saving meets the light-weighted requirement of industry, and three pin shaft forks is effectively reduced and three ball pin connection structures are using
In because of respective members the problem of being prone to wear that sliding friction reason causes, to reduce corresponding working service cost, mention
High corresponding service life.Therefore the utility model is a kind of very outstanding tripod universal joint assembly.
