Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a split half-axle for new energy vehicles. Background Art

[0002] The main function of the half shaft is to distribute the torque transmitted by the gearbox reducer to the left and right drive wheels. Universal joints are installed at both the inner and outer ends to achieve smooth power transmission. Half shafts are divided into full floating type and semi floating type. Full floating half shafts mainly transmit torque, but do not bear bending moment and reaction force, so they are widely used in various types of vehicles. This type of half shaft is easy to disassemble and assemble, and is more convenient for maintenance. Semi floating half shafts transmit torque, bear bending moment and reaction force, have a simple structure and low cost, and are suitable for vehicles with small reaction torque.

[0003] In new energy vehicles, the half shaft is a key component that transmits the torque of the drive motor to the wheels. However, traditional half shafts are usually integral structures, which have problems such as heavy weight, high cost, and difficult maintenance. In view of this, we propose a split half shaft for new energy vehicles. Utility Model Content
