Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, in a hub bearing with a cover-shaped structure, which is fastened with an anti-friction function, a hub bearing 10 is matched with a driving shaft 11 through a spline hole, and the hub bearing 10 and the driving shaft 11 are fastened by a driving shaft locking nut 12; the hub bearing 10 includes a fixed portion and a rotating portion; the fixing portion fixes the hub bearing 10 to the vehicle suspension; the rotating part is the part on the bearing that rotates with the drive shaft under the action of the drive torque.
The driving shaft 11 is connected with the hub bearing flange 3 in the hub bearing 10 through a spline and is locked and fixed by a driving shaft locking nut 12. The driving torque output by the power assembly is transmitted to the hub bearing flange 3 through the driving spline by the driving shaft 11, and then the function of driving the wheel to rotate is realized.
The fixed part comprises a hub bearing outer ring 1 and an outer side sealing ring 2; the hub bearing outer ring 1 is fixedly connected with a suspension.
The rotating part comprises a hub bearing flange 3, an inner steel ball 4, an outer steel ball 5, a hub bearing inner ring 6, an inner sealing ring 7, an antifriction cover 8 and a hub bolt 9; the antifriction cover 8 is buckled on the turning and riveting structure of the hub bearing flange 3; an inner side sealing ring 7 is arranged between the hub bearing outer ring 1 and the hub bearing inner ring 6; an outer side sealing ring 2 is arranged between the hub bearing outer ring 1 and the hub bearing flange 3; the inner steel balls 4 and the outer steel balls 5 are placed on the steel ball retainer; the hub bearing flange 3 is fixedly connected with a hub bolt 9; the outer side of the inner steel ball 4 is in contact with the hub bearing outer ring 1, and the inner side of the inner steel ball is in contact with the hub bearing inner ring 6; the inner side of the outer steel ball 7 is in contact with the hub bearing flange 3, and the outer side of the outer steel ball is in contact with the hub bearing outer ring 1.
The antifriction cover 8 takes a steel plate as a base material, and one side or two sides of the antifriction cover are coated with antifriction materials.
In the process of transmitting torque, the driving shaft 11 can generate elastic deformation under the action of driving torque, when the driving torque changes, the elastic deformation of the driving shaft 11 can also change, so that the contact surface of the driving shaft 11 and the hub bearing 10 forms sliding displacement, and due to the existence of the cover-shaped structure with the anti-friction function on the contact surface, the friction of the contact end surface of the driving shaft 10 and the hub bearing 10 is reduced, and the function of eliminating or weakening the sliding noise between the contact surfaces is realized.
Under the action of the locking torque of the driving shaft locking nut 12, the antifriction cover 8 on the hub bearing 10 bears the axial pressure of the driving shaft, and meanwhile, the antifriction cover 8 on the hub bearing 10 bears the sliding friction force between the driving shaft and the hub bearing in the process of the change of the driving torque, and due to the antifriction characteristic of the antifriction cover 8, the effect of eliminating or weakening the sliding friction noise is achieved.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.
Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.
