Description

Hub unit of inner ring channel curved surface compound mill

Technical Field

The utility model relates to the technical field of automobile hubs, in particular to a hub unit for inner ring channel curved surface compound grinding.

Background

The hub is the part of the wheel center where the axle is installed, namely the "rim" or "steel ring" of people's convention. The hub is easy to be stained with dirt, and if the hub is not cleaned for a long time, the hub is likely to be corroded and deformed, so that a potential safety hazard is generated. Care should therefore be taken to maintain the hub.

Due to different language habits of the wheel hubs, many people call the wheel hubs differently, such as the wheel rims, while many southern friends call the wheel hubs as the tire bells or the car bells, and thousands of people do not feel like the car bells when saying the car bells, and then the people can mistakenly speak the car bells.

The hubs on the market can be divided into steel hubs and alloy hubs according to the materials, and the steel hubs and the alloy hubs have respective advantages and disadvantages. The main advantages of steel hubs are the relatively low cost of the manufacturing process (casting is generally adopted, for example, aluminum alloy hubs are generally produced by low-pressure casting process), and the strong metal fatigue resistance, namely, the steel hubs are cheap and solid. However, the steel hub has relatively outstanding defects, namely, the steel hub is ugly in appearance (no appearance), heavy in weight (the same hub steel material is much heavier than an aluminum alloy material), large in inertial resistance, poor in heat dissipation and easy to rust. The alloy hub can exactly solve the problems, has light weight, small inertia resistance, high manufacturing precision, small deformation during high-speed rotation and small inertia resistance, is favorable for improving the straight-line driving performance of an automobile and reducing the rolling resistance of a tire, thereby reducing the oil consumption. The alloy material has heat conductivity about three times that of steel, good heat dissipation performance and certain effect on the thermal attenuation of a braking system, a tire and the braking system of a vehicle. Alloy hubs of original factory vehicles in the market are mainly made of aluminum alloy, and elements such as chromium and titanium are selected as basic materials for achieving certain special requirements and improving vision of a plurality of modified hubs. However, compared with a steel hub, the alloy hub is expensive, so that the steel hub is usually found in low-end-level original trucks, and the alloy hub is standard of a high-end-level truck.

The automobile hub is generally used for being connected with a transmission shaft and driving wheels to rotate in the using process, lubrication is generally needed on a connecting part, and the existing automobile hub generally has the defect of incapability of automatic lubrication, so that the service life is short.
