Description
Technical Field
The utility model relates to an automobile parts's field, concretely relates to reduce structure in commercial car steering column rzeppa constant velocity universal joint circumference clearance.
Background
The steering column of the commercial vehicle is a connecting part arranged between a steering wheel and a steering transmission shaft and is mainly used for controlling the advancing direction of the vehicle, transmitting torque and absorbing energy generated when the vehicle is collided. The original commercial vehicle steering column is connected with the steering transmission shaft through a cross shaft structure to achieve the steering function. The structure of the ball cage type constant velocity universal joint can obtain a larger swing angle compared with the original cross shaft structure, so that the turning force during turning is reduced for automobile drivers, and the application of the ball cage type constant velocity universal joint is adopted on more and more commercial vehicle steering columns.
The rzeppa constant velocity universal joint is of a spherical rotating structure and has a large rotating angle. However, due to the requirements for lubrication, manufacture, and assembly, there are gaps between the parts in the birfield type constant velocity universal joint, thereby generating a circumferential gap, causing vibration and noise during the driving of the automobile, and affecting the reliability and life of the product, and therefore, there is a need to design a structure for reducing the circumferential gap of the birfield type constant velocity universal joint in a steering column of a commercial vehicle.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a structure that reduces ball cage constant velocity universal joint circumference clearance in commercial car steering column.
The purpose of the utility model is accomplished through following technical scheme: the structure for reducing the circumferential clearance of the ball-cage type constant velocity universal joint in the steering column of the commercial vehicle mainly comprises a bell-shaped shell, a connecting shaft and a steel wire check ring, wherein a retainer is arranged in the bell-shaped shell, an inner star-shaped sleeve is arranged in the retainer, a steel ball matched with the star-shaped sleeve is arranged in the retainer, a thimble is arranged in the bell-shaped shell, the end surface of the thimble is mutually supported with a small thimble arranged in the connecting shaft, the tail end of the small thimble is matched and connected with a compression spring arranged in the connecting shaft, a clamp spring groove is formed in the head of the connecting shaft and used for being fixed with an inner cavity of the star-shaped sleeve through the steel wire check ring.
Furthermore, the outer spherical surface of the star-shaped sleeve matched with the retainer is provided with a section of inclined surface, so that the star-shaped sleeve can perform circular rotation movement and axial movement in the retainer.
The utility model has the advantages that:
1. the arrangement of the inclined plane structure with the included angle of 12 degrees on the outer spherical surface matched with the retainer of the inner star sleeve ensures the characteristic that the inner star sleeve can move axially when performing circular rotation motion in the retainer, reduces the gap problem existing after the inner star sleeve and the outer bell shell are installed, and avoids the problems that the inner circumferential gap of the rzeppa universal joint is too large, and the product generates abnormal sound, vibration and the like to influence the reliability and the service life of the product.
2. The thimble of bell shell internally mounted and the little thimble of connecting axle internally mounted hold each other, because compression spring is installed to little thimble afterbody, so can increase the dynamics of jacking each other with little thimble in the connecting axle and the bell shell for the thimble of bell shell internally mounted and the little thimble of connecting axle internally mounted are inseparabler each other, and the inside circumference clearance of very big elimination device has increased the practicality of device.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
FIG. 2 is an enlarged partial view of the inner race.
Description of reference numerals: the device comprises an outer shell 1, a retainer 2, a star-shaped sleeve 3, a steel ball 4, a thimble 5, a small thimble 6, a compression spring 7, a connecting shaft 8 and a steel wire retainer ring 9.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawing, the structure for reducing the circumferential clearance of the rzeppa constant velocity universal joint in the steering column of the commercial vehicle mainly comprises a bell-shaped shell 1, a connecting shaft 8 and a steel wire retaining ring 9, wherein a retainer 2 is arranged in the bell-shaped shell 1, an inner star sleeve 3 is arranged in the retainer 2, a steel ball 4 matched with the star sleeve 3 is arranged in the retainer 2, an ejector pin 5 is arranged in the bell-shaped shell 1, the end surface of the ejector pin 5 is mutually propped against a small ejector pin 6 arranged in the connecting shaft 8, the tail end of the small ejector pin 6 is matched and connected with a compression spring 7 arranged in the connecting shaft 8, a clamp spring groove is arranged at the head of the connecting shaft 8 and used for being fixed with an inner cavity of the star sleeve 3 through the steel wire retaining ring 9.
Preferably, a section of inclined plane is arranged on the outer spherical surface of the star sleeve 3 matched with the retainer 2, and the angle A of the inclined plane is 12 degrees, so that the star sleeve 3 can perform both circular rotation motion and axial motion in the retainer 2.
The utility model ensures that the star cover can axially move when circularly rotating in the retainer through the arrangement of the inclined plane structure with the included angle of 12 degrees on the outer spherical surface matched with the retainer, and the compression spring is arranged at the tail end of the small thimble arranged in the thimble and the connecting shaft arranged in the bell-shaped shell, so that the thimble and the small thimble are tightly propped against each other, and the circumferential clearance when the bell-shaped shell and the star cover are arranged is reduced as much as possible through the fixation of the star cover and the connecting shaft; in fact, the excessive circumferential clearance can influence the reliability and the service life of the product, therefore the utility model discloses the reliability of product has been improved on the whole.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
