The invention discloses an automobile wheel hub unit with a self-locking device. The automobile wheel hub unit comprises a wheel hub flange, wherein a wheel hub rim is arranged on one side of the wheel hub flange; a wheel hub bead seat is arranged on the inner wall of the wheel hub rim; a wheel hub spoke is arranged on the surface of the wheel hub rim; a wheel hub groove bottom is arranged on the inner wall of the wheel hub flange; a tire air valve hole is formed in the wheel hub groove bottom; a wheel hub mounting hole is formed in the wheel hub spoke; the wheel hub spoke is provided with a wheel hub self-locking ratchet; and a self-locking probe is arranged at the outer part of the wheel hub self-locking ratchet. According to the automobile wheel hub unit, after a ratchet self-locking structure is additionally arranged on the wheel hub unit, the safety of an automobile is improved; when the automobile flames out accidentally or when the automobile stops and a handbrake is not pulled down, an automobile sliding condition does not occur; a magnetic coil and the ratchet are matched with each other to form the self-locking structure; and structurally, the automobile wheel hub unit has a very simple structure and is convenient to mount and the cost is also saved.
Description
technical field [0001] The invention belongs to the technical field, and in particular relates to an automobile wheel hub unit with a self-locking device. Background technique [0002] In the prior art, the wheel hub is also called the rim, the steel ring, the wheel, and the tire bell. It is a drum-shaped, center-mounted metal part that supports the tire inside the tire. There are many types of hubs according to diameter, width, molding method, and material. In the past, most of the hub bearings of cars used single-row tapered roller or ball bearings in pairs. With the development of technology, cars have widely used car hub units. The use range and amount of hub bearing units are increasing day by day, and it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fit the bearing on the wheel shaft and fix it with nuts. ...
