Problems solved by technology

This technology has the following disadvantages: the use of circlips and gaps on the semi-shafts lead to the concentration of stress on the axle shaft material, and the diameter of the semi-shafts becomes smaller, which is prone to breakage of the semi-shafts during driving, resulting in traffic accidents

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0013] Such as figure 1 As shown, an electric vehicle axle disc brake hub structure for a vehicle includes an axle main shaft 1, a hub 2 and a disc brake device. A differential box 5 is provided in the middle of the axle main shaft 1, and both ends of the axle main shaft 1 are respectively A hub 2 is provided. The inner side of the hub 2 at both ends of the axle shaft 1 is respectively provided with a disc brake assembly flange 3, the inner side of the disc brake assembly flange 3 is respectively provided with a bearing sleeve 7, and the inner side of the bearing sleeve 7 is respectively provided with a skateboard bracket 4 .

[0014] In this embodiment, a bridge tube 6 is provided between the axle shaft 1 and the hubs 2 on both sides thereof, the bearing sleeve 7 is provided at the end of the bridge tube 6, and the sliding plate bracket 4 is provided on the br...

Abstract

The invention relates to an electric vehicle axle disc brake hub structure. The structure includes an axle spindle, hubs and disc brake devices. A differential case is arranged in the middle of the axle spindle. The hubs are arranged on the two ends of the axle spindle. Disc brake assembly flanges are arranged on the inner sides of the hubs at the two ends of the axle spindle. A bearing sleeve isarranged on the inner side of each disc brake assembly flange. A slide plate bracket is arranged on the inner side of each bearing sleeve. Axle pipes are arranged between the axle spindle and the hubsat the two ends of the axle spindle. Each bearing sleeve is arranged on the end part of the corresponding axle pipe. Each slide plate bracket is arranged on the corresponding axle pipe. The differential case is arranged on the side of the axle spindle of the driving direction. A disc brake sheet is arranged on each disc brake assembly flange. Compared with the prior art, the electric vehicle axledisc brake hub structure uses the bearing sleeves to restrict the movement of the vehicle axle bearing, can keep the diameter of the half axle unchanged, and can avoid stress concentration of a vehicle axle material, thereby greatly improving the fatigue resistance of the axle. The electric vehicle axle disc brake hub structure is safe and reliable in use.

Description

Technical field [0001] The invention relates to the technical field of motor vehicles, in particular to an axle disc brake hub structure mainly used for electric vehicles. Background technique [0002] As the main force of new energy vehicles, electric vehicles are increasingly entering people's lives, and their driving technology is quite different from traditional internal combustion engine vehicles. In general electric vehicles, the electric motor transmits force to the wheel hub, and the wheel hub is connected with the brake disc in contact with it, and the brake disc is connected with the corresponding parts on the wheel with screws to realize the braking of the wheel. The direct plane contact area between the brake disc and the hub is small. When braking, a lot of torque is generated between the brake disc and the hub. Even if the brake disc and the hub are connected by screws, there is a certain friction, but the screws and the brake disc There will always be some gaps be...
