Abstract
A double ball ring three ball pin assembly mainly solves the problem that a pivot angle of an existing three ball pin cardan joint is small and comprises a three-pin frame (1), ball rings (2), roller pins (3) and check rings (4). Three hinge pins (11) are arranged on the three-pin frame (1), the ball rings (2) are mounted on the hinge pins (11), the roller pins (3) are arranged between the ball rings (2) and the hinge pins (11), and the ball rings (2) and the roller pins (3) are limited through gaskets (5), the check rings (4) and elastic check rings (6). The double ball ring three ball pin assembly is characterized in that outer ball rings (7) are arranged outside the ball rings (2), inner bores of the outer ball rings (7) are conical bores with big internals and small externals, and the outer ball rings (7) can obliquely rotate in arbitrary directions relative to the ball rings (2). According to the double ball ring three ball pin assembly, a double ball ring structure is adopted, the outer ball rings and the hinge pins on the three-pin frame can obliquely rotate, and thus the pivot angle of the three ball pin cardan joint is enlarged.
Description
Technical field
The utility model relates to a kind of universal joint, is specifically related to a kind of pair of ball three ball pin assemblies.
Background technique
Tripod universal joint is crucial transmission part in the car drivetrain system, mainly is comprised of three ball pin shells and three ball pin assemblies, and three ball pin assemblies place in the three ball pin shells and by three ball pin retainer ring spacings.Existing three ball pin assemblies mainly are comprised of spider, ball, needle roller and back-up ring, spider is provided with three bearing pins, ball is installed on the bearing pin, be provided with needle roller between ball and the bearing pin, ball can only circumferentially rotate relative to the bearing pin center, can not deflection, therefore, just by the decision of the pivot angle between three ball pin shells and three ball pin assemblies, pivot angle is subjected to structural limitations to the pivot angle of tripod universal joint, and pivot angle is less.
The model utility content
In order to solve the less problem of existing tripod universal joint pivot angle, the utility model provides a kind of pair of ball three ball pin assemblies, this pair ball three ball pin assemblies adopt two ball structures, can deflections between the bearing pin on outer ball and the spider, increased the pivot angle of tripod universal joint.
The technical solution of the utility model is: a kind of pair of ball three ball pin assemblies, comprise spider, ball, needle roller and back-up ring, spider is provided with three bearing pins, ball is installed on the bearing pin, be provided with needle roller between ball and the bearing pin, ball and needle roller are spacing by pad, back-up ring and circlip, and ball is provided with the ectosphere ring outward, the endoporus of outer ball is interior large outer little conical bore, the relatively ball any direction deflection of outer ball.
The outer spherical surface of described outer ball is eccentric spherical.
The cone angle alpha of the endoporus of described outer ball is 0.5 °～1.5 °.
The utlity model has following beneficial effect: owing to taking such scheme, slideway in outer ball and the three ball pin shells cooperates, outer ball can again relatively ball deflection of relative three ball pin shell deflections, has increased the pivot angle of tripod universal joint, has improved the performance of universal joint.
Description of drawings
Accompanying drawing 1 is structure sectional view of the present utility model.
Accompanying drawing 2 is structural representations of Fig. 1 China and foreign countries ball 7.
1-spider among the figure, 11-bearing pin, 2-ball, 3-needle roller, 4-back-up ring, 5-pad, 6-circlip, the outer ball of 7-, α-cone angle.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of pair of ball three ball pin assemblies comprise spider 1, ball 2, needle roller 3 and back-up ring 4, spider 1 is provided with three bearing pins 11, ball 2 is installed on the bearing pin 11, be provided with needle roller 3 between ball 2 and the bearing pin 11, ball 2 and needle roller 3 are spacing by pad 5, back-up ring 4 and circlip 6, the ball 2 outer ectosphere rings 7 that are provided with, the endoporus of outer ball 7 is interior large outer little conical bore, the relatively ball 2 any direction deflections of outer ball 7.Owing to taking technique scheme, the interior slideway of outer ball 7 and three ball pin shells cooperates, and outer ball 7 can again relatively ball 2 deflections of relative three ball pin shell deflections, has increased the pivot angle of tripod universal joint, has improved the performance of universal joint.
The outer spherical surface of described outer ball 7 is eccentric spherical.Slideways suitable and in the three ball pin shells cooperate.
The cone angle alpha of the endoporus of described outer ball 7 is 0.5 °～1.5 °.This angle draws according to designing and calculating, and it is 1 ° that the present embodiment is chosen cone angle alpha.
Claims (3)
1. two ball three ball pin assemblies, comprise spider (1), ball (2), needle roller (3) and back-up ring (4), spider (1) is provided with three bearing pins (11), ball (2) is installed on the bearing pin (11), be provided with needle roller (3) between ball (2) and the bearing pin (11), ball (2) and needle roller (3) are by pad (5), back-up ring (4) and circlip (6) are spacing, it is characterized in that: the outer ectosphere ring (7) that is provided with of ball (2), the endoporus of outer ball (7) is interior large outer little conical bore, relatively ball (2) any direction deflection of outer ball (7).
2. according to claim 1 pair of ball three ball pin assemblies, it is characterized in that: the outer spherical surface of outer ball (7) is eccentric spherical.
