Description
Technical field
The utility model relates to universal joint field, particularly a kind of directional rzeppa universal joint.
Background technique
Fixed center type ball-and-cage constant velocity universal joint is the critical component in automobile constant velocity universal joint drive spindle, the usability of fixed center type ball-and-cage constant velocity universal joint and quality life-span directly affect the view of people to automobile itself, along with popularizing of automobile, the travelling comfort of people to vehicle operation performance and use requires more and more higher.For a long time, center fixed ball cage type constant velocity universal joint also exists all the time in using process and easily produces noise and vibration, short-life defect, and this universal joint of RN-63013 especially in West Europe car system, exists this problem in production process for many years always.
Because its star jacketed-ball groove and steel ball point of contact position adopt miter angle, the people such as Institutes Of Technology Of Nanjing Wang Liang mould are through the most easily occurring on the surface of contact of the ball receway of star sleeve to the analysis of the stress that this contact angle distributes with the fatigue ruption calculating this type of universal joint, cause pockmark, peel off and spot corrosion, its fundamental cause is star sleeve, when bell housing alley is identical with the wrapping angle of steel ball, the contact stress of star jacketed-ball groove is than stress large 1/3rd suffered by bell housing alley, this causes the star sleeve life-span lowly to cause the short-life reason of whole universal joint.In addition, rzeppa universal joint is made up of bell housing, star sleeve, retainer, steel ball four parts, one group of spherical pair is formed by bell housing inwall and retainer outer wall, other one group of spherical pair is formed by retainer inwall and star sleeve outer wall, two groups of spherical pairs remain universal energy-conservation realization around a Fixed-point Motion of A, Just because of this, this cooperation that just decide between these two groups of spheres must be Spielpassung, also there is radial clearance because the existence of this gap just decides universal joint; Simultaneously because universal joint subjects axial action, axial internal clearance will be produced, existence due to radial and axial play just makes automobile can produce vibration & noise in motion, make star sleeve, retainer, steel ball etc. can there is play, impact in the process of moving, exacerbate the inefficacy of universal joint.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of directional rzeppa universal joint, improves working life, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technological scheme: a kind of directional rzeppa universal joint, comprise driving shaft, outer cover, star sleeve, ball, retainer and spherical shell, described driving shaft is connected with star sleeve, star sleeve is arranged on the inside of retainer, the sidewall of star sleeve is provided with six grooves, described retainer is the collar, the sidewall of the collar is provided with six through holes, described ball is arranged between star sleeve and retainer, be stuck between groove and through hole, the inwall of described spherical shell is provided with six alleys, spherical shell parcel retainer, ball is stuck in alley, outer cover is connected with spherical shell, form the cavity of opposing seal, described driving shaft is through outer cover, the back side of spherical shell is provided with driven shaft.
Preferably, the inner chamber of described spherical shell is provided with shoe cream room.
Preferably, spline joint between described driving shaft and star sleeve, is located by snap ring.
Preferably, be located by connecting by little steel strap between described driving shaft and outer cover.
