Description
Technical Field
The utility model relates to an use nine ball way ball formula steering transmission shaft structures on steering transmission shaft among the automotive technology field.
Background
At present, a steering transmission shaft is a key part of an automobile steering device, and the main function of the steering transmission shaft is to transmit the rotating torque of a steering wheel to a steering machine so as to realize the steering operation of the whole automobile. The traditional steering transmission shaft has no steel balls and steel ball retainer structures, the surface of the transmission shaft is in matched contact with the transmission shaft sleeve through an injection molding spline or nylon coating, and the contact medium of the transmission shaft and the transmission shaft sleeve is the excircle surface of the injection molding spline or the nylon coating spline of the transmission shaft and the inner circle surface of the transmission shaft sleeve, and is typical surface-surface contact. Reducing the contact area of transmission shaft and driving sleeve is the key to solve above-mentioned problem, and it is necessary to design a cooperation structure that can reduce the contact area of transmission shaft and driving sleeve to reduce frictional force, improve the life who turns to the transmission shaft. Therefore, it is a new problem to be solved urgently to develop a nine-ball-way ball type steering transmission shaft structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a nine lane ball formula steering transmission shaft structure, this utility model is poor for solving steering transmission shaft because the steering transmission shaft that transmission shaft and driving sleeve frictional resistance caused is big, the problem that life is low, this steering transmission shaft structure adopts the steel ball as the contact medium of transmission shaft and driving sleeve interior disc, compare with the face and the face contact of traditional transmission shaft structure, area of contact has been reduced, frictional resistance has been reduced, and the transmission shaft, the lane and the steel ball surface of driving sleeve all carry out thermal treatment, hardness is higher, the wearability is good, steering transmission shaft's life has been improved.
The purpose of the utility model is realized like this: the utility model provides a nine lane ball formula steering transmission shaft structure, includes driving sleeve, retaining ring, steel ball holder, transmission shaft, sealed lid, steel ball mounting hole, C type crack structure that disappears, 6 rows of steel ball mounting holes and 3 rows of C type crack structures that disappears are distributed on the circumference of steel ball holder, and every row of steel ball mounting hole has 6 steel ball mounting holes, and the steel ball is installed on the steel ball holder, and the retaining ring and the steel ball holder of installation steel ball are connected with the transmission shaft, and transmission shaft and steel ball holder are installed in the driving sleeve, and the retaining ring is installed at the transmission shaft front end, and sealed lid is installed in driving sleeve one end.
The main point of the utility model lies in its structure. The working principle and the using operation method are that the transmission shaft drives the steel ball retainer and the steel ball to move under the action of external force, and the steel ball can automatically roll in the steel ball retainer, is in contact with the inner circle surface of the transmission shaft sleeve and can freely roll on the inner circle surface of the transmission shaft sleeve, so that the friction resistance is obviously reduced. The transmission shaft and the steel ball are in direct contact with the transmission shaft sleeve to transmit steering torque. 6 steel balls are arranged in each row, and 6 rows of the steel balls are arranged on the steel ball retainer and are used as contact media with the inner circular surface of the transmission shaft sleeve; lubricating grease is filled between the transmission shaft sleeve and the steel ball retainer; the transmission shaft adopts a special-shaped shaft with nine ball tracks. The transmission shaft sleeve is made of a special-shaped steel pipe with nine ball tracks.
Compared with the prior art, the nine-lane ball type steering transmission shaft structure has the advantages that the structure is simple, the steel ball is used as a contact medium of the transmission shaft and the transmission shaft sleeve, the contact area between the transmission shaft and the transmission shaft sleeve is effectively reduced, the friction resistance is reduced due to rolling friction, the hardness of the transmission shaft, the transmission shaft sleeve and the steel ball is high after surface heat treatment, the wear resistance is good, the service life of the steering transmission shaft is prolonged, and the nine-lane ball type steering transmission shaft structure can be widely applied to the technical field of automobiles.
