Abstract
The utility model provides a kind of three bearing pins, it comprises a spherical body and three columniform pin diameter, those pin diameter are uniformly distributed in the outside of this spherical body, the axes normal of this pin diameter is in the axis of this spherical body, the axis of all pin diameter is uniformly distributed on same plane, each pin diameter is equipped with a plunger, the outer surface of all plungers is positioned on same sphere.The utility model compact structure, easy accessibility, bearing capacity are strong, adopt the utility model can strengthen flexible slippage and operating angle allowable, alleviate the vibration of transmission shaft.
Description
Technical field
The utility model relates to vehicle transmission shaft device, three bearing pins particularly in a kind of vehicle transmission shaft device.
Background technique
Constant velocity universal joint is the vitals in car transmissions, is made up of housing, three bearing pins, needle roller, ball and transmission shaft etc.Constant velocity universal joint and speed changer link together, and by the ball of three between housing and three bearing pins, the power at constant speed of speed changer are transmitted to truck drive shaft.Three bearing pins are the necessary structures in variable-speed dynamic transmittance process, and the quality of its contact stress and service behaviour directly affects the functional reliability of car load.
Need after three traditional bearing pin turning needle roller is installed, not only consuming time, and dismounting inconvenience.The assembling of needle roller makes pin diameter need to be processed when forging three bearing pin partially long, correspondingly, needs the thickness and the spherical radius that strengthen the ball be arranged in pin diameter, flexible slippage is affected, in a disguised form have impact on operating angle allowable.Wherein, operating angle allowable is the maximum functional angle of the energy-conservation swing of constant velocity universal, and flexible slippage is the flexible slippage stroke that constant velocity universal joint is allowed vertically.
Model utility content
The technical problems to be solved in the utility model need be installed needle roller cause flexible slippage and the affected defect of operating angle allowable to overcome three bearing pins in prior art, provides a kind of without the need to installing needle roller, can strengthening three bearing pins of flexible slippage and operating angle allowable.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of three bearing pins, it comprises a spherical body and three columniform pin diameter, those pin diameter are uniformly distributed in the outside of this spherical body, the axes normal of this pin diameter is in the axis of this spherical body, the axis of all pin diameter is uniformly distributed on same plane, its feature is, each pin diameter is equipped with a plunger, and the outer surface of all plungers is positioned on same sphere.
In the utility model, " spherical " and " circle " is non-essential in complete three-dimensional sphere, and only refers to that the part external frame of corresponding part meets spherical shape.Particularly, in this programme, the lower plane of spherical body is a bottom plane, is provided with a circular cavity in this spherical body, and the upper plane of this circular cavity is a location datum plane.Each pin diameter is equipped with a plunger, plunger and columniform pin diameter one-body molded.Structure and the ball of plunger match, and namely the internal diameter of ball is greater than the external diameter of plunger.When installing this three bearing pin, ball is directly installed in pin diameter, pin diameter and ball are arranged in the space corresponding to housing, eliminate needle roller, the thickness and the spherical radius that are arranged on the ball in pin diameter correspondingly shorten, this plunger increases flexible slippage and operating angle allowable when working in housing and ball, alleviate the vibration of transmission shaft.
Preferably, the side of this pin diameter is arc-shaped.
Preferably, this spherical body, those pin diameter and those plungers are one-body molded.This three bearing pin be processed as forging forming, do not need to process plunger in addition, this three bearing pin rotates in speed change and has during acute impact load and can bear larger contact stress.In addition, this three bearing pin is that warm forging is shaping, adopts warm forging technique can improve precision and the quality of three bearing pin forging.
Positive progressive effect of the present utility model is: the utility model compact structure, easy accessibility, bearing capacity are strong, adopts the utility model can strengthen flexible slippage and operating angle allowable, alleviates the vibration of transmission shaft.

Fig. 3 is the sectional view of Fig. 2 along A-A direction.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As depicted in figs. 1 and 2, three bearing pins of the present embodiment comprise a spherical body 1 and three columniform pin diameter 2.Wherein, the lower plane of spherical body 1 is a bottom plane 3, is provided with a circular cavity 4 in this spherical body 1, and the upper plane of this circular cavity 4 is a location datum plane 5; Three pin diameter 2 are uniformly distributed in the outside of this spherical body 1, and be separated by 120 ° between three pin diameter 2, the axes normal of this pin diameter 2 is in the axis of this spherical body 1, the axis of all pin diameter 2 is uniformly distributed on same plane, each pin diameter 2 is equipped with a plunger 6, the outer surface of all plungers 6 is positioned on same sphere 7.
As shown in Figure 3, the side of this pin diameter 2 is arc-shaped, and this plunger 6 is one-body molded with columniform pin diameter 2.This three bearing pin is forging forming, rotates and has during acute impact load can bear larger contact stress in speed change.
When adopting three bearing pin work of the present utility model, power is exported by truck drive shaft, driving shaft and housing.When installation three bearing pin, ball is directly installed in pin diameter, has shortened thickness and the spherical radius of ball, increases flexible slippage and operating angle allowable.When under the complex working condition that master and slave moving axis has certain angular displacement and axial displacement simultaneously, structure of the present utility model ensure that three bearing pins and ball still can very steadily, flexibly, reliably and accurately transmit in housing and moves and torque, smoothly sphere-contact solve mobile cause pockmark, peel off and spot corrosion, contact all right.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
