Technical Field
The utility model belongs to the technical field of the car transmission shaft, especially, relate to a lightweight car transmission shaft forging structure.
Background
A forging is a process flow, which refers to an object in which a metal is pressed to form a desired shape or a suitable compressive force by plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process builds a fine grain structure and improves the physical properties of the metal. In the actual use of the components, a proper design enables the flow of particles in the direction of the main pressure. The transmission shaft is an important part for transmitting power in an automobile transmission system, and the transmission shaft, a gearbox and a drive axle are used for transmitting the power of an engine to wheels so that an automobile generates driving force. In order to ensure the structural strength of the automotive propeller shaft, it is generally processed by a forging process. If the transmission shaft is designed to be light, the transmission shaft is generally formed by roll welding thin steel plates with the thickness of 1.5-3 mm. In a universal drive of a steering drive axle or a miniature vehicle, the propeller shaft is usually made as a solid shaft.
In the driving process of an automobile, the transmission shaft drives wheels to rotate at a high speed, when the rotation frequency of the transmission shaft is consistent with the inherent modal frequency of the transmission shaft, the transmission shaft can resonate, the vibration of the whole automobile is further increased, the transmission shaft can be fatigued and damaged in serious conditions, traffic accidents are caused, and even unreasonable results are caused. Therefore, stability of the transmission torque of the propeller shaft is important. In addition, the joint of the transmission shaft and the universal joint fork is lack of protection in the vibration process, so that the transmission shaft is more easily damaged due to connection stress, and the service life of the transmission shaft is shortened.
