Description

Technical Field

[0001] This utility model belongs to the field of automotive component technology and relates to an electromagnetic clutch front axle. Background Technology

[0002] The front axle is a crucial component of a car's front end. It's the device that transmits forces and the resulting bending moments and torques between the chassis and the front wheels. Simply put, the front axle is like the car's "front legs," supporting the weight of the front of the vehicle and transmitting engine power to the front wheels, enabling the car to move forward, steer, and brake.

[0003] The patent for an overrunning clutch-type electronically controlled limited-slip differential drive axle with publication number CN208858891U has been published on the China Patent Network. This patent can achieve bidirectional wedging in both forward and reverse driving, and the switching between two-wheel drive and four-wheel drive is convenient, flexible, and reduces the sense of jerking.

[0004] However, although the above-mentioned patent uses a sliding sleeve to connect the two inner spline platforms, the outer circles of the two inner splines are still in contact. When the two inner spline platforms rotate relative to each other, a large area of ​​relative friction will be generated. The large friction will cause the two inner spline platforms to generate a large resistance when rotating relative to each other, affecting the transmission efficiency. Therefore, designing an electromagnetic clutch front axle is of great significance. Summary of the Invention
