A heavy-duty car wheel hub with a protective device

Abstract

The invention relates to the technical field of hubs, in particular to a heavy automobile hub with a protective device. Through the design of a soft buffered wheel disc device, relative rotation occurs between a transmission shaft and a wheel hub during emergent acceleration or emergent braking, impact on the wheel hub is buffered by a buffer spring, impact force acting on the wheel hub is reduced, the impact effect on the wheel hub is greatly reduced, the service life of the wheel hub is prolonged, the safety coefficient is high, and the problem that the dangerousness is extremely high sincethe powerful torque acts on the wheel hub directly during emergent acceleration or emergent braking of a vehicle, the impact and bearing of the wheel hub are greater, and the phenomenon such as deformation or even fracture of a tire can appear after long-time use is solved; relative rotation occurs between the tire and the transmission shaft, the impact force of emergent braking and emergent acceleration is weakened through the buffer spring, and the vehicle travels relatively smoothly; after braking, a part of energy is stored in the buffer spring, a part of power can be provided through thebuffer spring during starting, and the load of an engine is small, so that power and oil are relatively saved.

Description

technical field [0001] The invention relates to the technical field of wheel hubs, in particular to a heavy-duty automobile wheel hub with a protective device. Background technique [0002] The hub is a barrel-shaped, center-mounted metal part on the axle that supports the tire inside the tire. Also known as rims, steel rims, wheels, and tire bells. There are many types of hubs according to diameter, width, molding method, and material; when the vehicle accelerates or brakes suddenly during driving, a strong torque force is directly applied to the hub through the interaction between the tire and the drive shaft, and the hub impacts and bears If the tire is larger, the tire will be deformed or even cracked after long-term use, which is extremely dangerous. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heavy-duty automobile wheel hub with a protective device for the above-mentioned technical deficiencies.

[0003] The technical problem to be solved by the present invention is to provide a heavy-duty automobile wheel hub with a protective device for the above-mentioned technical deficiencies. The design of the soft buffer wheel device is adopted to prevent the gap between the transmission shaft and the wheel hub during sudden acceleration or sudden braking. The relative rotation occurs between them, and the impact force on the hub is buffered by the buffer spring, the impact force acting on the hub is slowed down, which greatly reduces the impact of the hub, the service life of the hub becomes longer and the safety factor is high, which solves the problem of sudden acceleration or sudden braking of the vehicle The strong torque force is directly applied to the wheel hub, and the impact and load of the hub are relatively large. After a long time of use, the tire will be deformed or even ruptured, which is extremely dangerous; the relative rotation of the tire and the transmission shaft is weakened by the buffer spring. With the impact of sudden braking and rapid acceleration, the vehicle runs relatively smoothly; after braking, part of the energy is stored in the buffer spring, and a part of the power can be provided by the buffer spring when starting, and the engine load is small and fuel-efficient
