Description
Technical field
The utility model belongs to field of automobile parts and components, is related to a kind of sliding universal joint assembly of three ball pins.
Background technique
The high-performance constant velocity shaft assembly of passenger car is usually by fixed joint, sliding universal joint and connection
Jackshaft between universal joint is constituted.Sliding universal joint includes tripod and ball cage type, uses three balls currently on the market
It is more to sell sliding universal joint comprising sliding sleeve and trident bearing assembly, trident bearing assembly can slide in sliding sleeve, trident
Bearing assembly includes bearing bracket stand, is uniformly arranged on bearing bracket stand there are three pin shaft, is respectively arranged with bearing outer ring, needle roller, baffle ring on pin shaft
And snap ring, the outer end of needle roller are limited by baffle ring and snap ring, this infrastructure cost is low, structure is simple, light-weight, so
What is used is commonplace.But due to bearing outer ring outer surface and sliding sleeve raceway, inner surface and needle roller, needle roller and bearing bracket stand pin
Contact area is big when axis moves, and lubricates insufficient, generates biggish frictional resistance, but due between outer ring and needle roller not around Y
The freedom degree that axis is swung, influences the transmission efficiency, NVH performance and universal joint pivot angle range of vehicle.
Utility model content
The purpose of this utility model is exactly to solve the above-mentioned problems in the prior art, provide it is a kind of lubrication sufficiently, rub
Wipe the sliding universal joint assembly of three ball pins that power is small, overall transmission efficiency is high, operational shock is small, work pivot angle is big.
To achieve the above object, the technical solution of the utility model is: a kind of sliding universal joint assembly of three ball pins,
It includes sliding sleeve and the trident bearing assembly that is located in sliding sleeve；Cutting for the sliding of trident bearing assembly is provided in the sliding sleeve
Face is the raceway of arc；Trident bearing assembly includes the intermediate bearing bracket stand for being equipped with involute spline, is uniformly arranged on bearing bracket stand
Bearing outer ring, needle roller, baffle ring and the snap ring being equipped on three pin shafts and each pin shaft；The bearing outer ring spherical outside surface with
The raceway of sliding sleeve matches, and groove is provided on bearing outer ring spherical outside surface or is laser-etched with rough surface；In the bearing outer ring
Surface matches with needle roller, and bearing outer ring inner surface and needle roller are respectively corresponding spindle.
The bearing outer ring inner surface and needle roller of the utility model are respectively corresponding spindle, it is easier to form oil film, mention
High efficiency；The pivot angle range of universal joint is increased simultaneously.It is provided with groove on bearing outer ring spherical outside surface or is laser-etched with thick
Matte can sufficiently provide grease lubrication to working region.The utility model lubrication is abundant, frictional force is small, overall transmission efficiency
Height, operational shock is small, work pivot angle is big.

Specific embodiment
The utility model will be further described in the following with reference to the drawings and specific embodiments
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the present embodiment includes sliding sleeve 1 and is located at intracavitary three in sliding sleeve 1
Fork bearing assembly.The raceway that the section slid for trident bearing assembly is arc is provided in sliding sleeve 1, trident bearing assembly includes
Three pin shafts with its one that centre is equipped with the bearing bracket stand 3 of involute spline, is uniformly arranged on bearing bracket stand 3, on each pin shaft
Equipped with bearing outer ring 2, needle roller 6, baffle ring 4 and snap ring 5.2 spherical outside surface of bearing outer ring and the raceway of sliding sleeve 1 match, in axis
Groove 7(is processed on 2 spherical outside surface of bearing outer-ring can also be the rough surface of laser ablation), grease can store in groove 7 or laser
In etching, in operation process, two sides working region grease is provided, forms film lubrication, reduces frictional resistance, to improve bearing
Transmission efficiency.2 inner surface 8 of bearing outer ring and needle roller 6 are processed into corresponding spindle, it is easier to oil film is formed, meanwhile, because
To be processed into spindle, outer ring can suitably be swung around pin shaft Y-axis, increase the pivot angle range of universal joint.Needle roller 6 is in axis
It is rolled on 3 pin shaft of bolster, groove or laser ablation, grease are processed on pin shaft can store in groove or in laser ablation, transport
During turning, two sides working region grease is provided, forms film lubrication, reduces frictional resistance, while needle roller 6 is processed into spindle
Shape, it is easier to form oil film.
Embodiment described above be only preferably with example shape, it is all in the utility model not to limit the utility model
Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model
Within enclosing.
