Abstract
An inner hub of an automobile is composed of an inner hub body (1), a hub center hole (2), a hub bearing installation hole (3), a hub bolt installation hole (4), an R3 transition arc (5), an R2.5 transition arc (6) and an R5 transition arc (7). The inner hub is characterized in that the inner hub body (1) is of a rotary round structure, the hub center hole (2) is formed in the center of the rotary round structure, the hub bearing installation hole (3) is formed in the left end of the hub center hole (2), and the diameter of the hub bearing installation hole (3) is larger than that of the hub center hole (2). Due to the arrangement of the multiple transition arcs, installation and detachment of a brake device are facilitated, larger friction resistance can be provided when a brake conducts braking, and then driving safety and vehicle traveling stability are improved.
Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of inner wheel hub for miniature car.
Background technology
Automobile inner wheel hub is the Main Auto member for fixing outer wheel hub tire and support running car are installed, automobile inner wheel hub divides driving inner wheel hub and non-driving inner wheel hub, drive on inner wheel hub and also need to configure brake gear, in vehicle traveling process, due to the effect producing with the friction on ground and frequently braking, can allow inner wheel hub and brake gear produce larger torsion, therefore the fixed form of wheel hub directly affects the safety performance of automobile, the automotive hub breakage that constantly occurred in recent years the running at high speed event of hurting sb.'s feelings, therefore the safety performance that improves automotive hub is the only way of development of automobile.For this reason, design a kind of high strength, automobile inner wheel hub easy for installation, for improving, vehicle operation performance and safety performance are significant.
Summary of the invention
The object of the invention is to solve the technical deficiency of above existence, a kind of novel automobile inner wheel hub is provided, under existing automotive hub structure prerequisite, improve automobile inner wheel hub safety performance, reduce the inner wheel hub that is provided with Fast Installation step that safety misadventure occurs.
Technical scheme of the present invention is achieved in the following ways: a kind of automobile inner wheel hub, formed by inner wheel hub main body, wheel hub centre hole, hub bearing mounting hole, boss bolt mounting hole, R3 transition arc, R2.5 transition arc, R5 transition arc, it is characterized in that: described hub body is revolution circular configuration, wheel hub centre hole is arranged on the circular structure centre of revolution, described hub bearing mounting hole is arranged on wheel hub centre hole left end, and hub bearing mounting hole diameter is greater than wheel hub center-hole diameter.
Described boss bolt mounting hole quantity is 5, and the center-point of boss bolt mounting hole becomes concentric structure with wheel hub centre hole line of centers, and 5 boss bolt mounting holes are that even circumferential distributes.
Described wheel hub centre hole is interior linear gear structure.
The present invention, owing to being provided with continuous transition arc, not only facilitates brake equipment Assembly &Disassembly, has also improved the safety performance of vehicle traveling process, has reduced the generation of vehicle failure.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is partial view of the present invention.
Fig. 3 is the left side view of Fig. 1.
In figure: 1 inner wheel hub main body, 2 wheel hub centre holes, 3 hub bearing mounting holes, 4 boss bolt mounting holes, 5 R3 transition arcs, 6 R2.5 transition arcs, 7 R5 transition arcs.
Detailed description of the invention
Known by Fig. 1, Fig. 2, Fig. 3, schematic diagram of the present invention, formed by inner wheel hub main body 1, wheel hub centre hole 2, hub bearing mounting hole 3, boss bolt mounting hole 4, R3 transition arc 5, R2.5 transition arc 6, R5 transition arc 7, described hub body 1 is revolution circular configuration, wheel hub centre hole 2 is arranged on the circular structure centre of revolution, described hub bearing mounting hole 3 is arranged on wheel hub centre hole 2 left ends, and hub bearing mounting hole 3 is greater than wheel hub centre hole 2.Described boss bolt mounting hole 4 quantity are 5, and the center-point of boss bolt mounting hole 4 becomes concentric structure with wheel hub centre hole 2 line of centerss, and 5 boss bolt mounting holes 4 are even circumferential distribution.Described wheel hub centre hole 2 is interior linear gear structure, and transmission shaft passes wheel hub centre hole 2 and matches with linear gear structure, and the bearing after passing wheel hub centre hole 2 and on hub bearing mounting hole 3 is fixed together.On described hub bearing mounting hole 3 cylindricals, be provided with R2.5 transition arc 6.On described wheel hub centre hole 2 cylindricals, be provided with continuous R5 transition arc 7, R2.5 transition arc 6, R3 transition arc 5, facilitate brake equipment Assembly &Disassembly, being designed with is like this beneficial to drg and provides larger friction drag in braking, thereby improves safety and the vehicle driving stability of driving.
