Independent suspension integrated wheel-side motor assembly

Abstract

An independent suspension integrated wheel-side motor assembly is mainly used for manufacturing pure electric vehicles. A disconnected suspension structure is adopted, and suspensions on the left sideand the right side are independently connected with a vehicle frame, so independence during vertical jumping of a left wheel end and a right wheel end is achieved; a motor is installed on a stand column and does not rotate along with a knuckle; a two-section type main pin and a coaxial speed reducer structure are adopted, so a space is provided for arrangement and power transmission of the motor.The motor, the wheel ends and the independent suspension structure are integrated, a traditional transmission shaft and variable box structure is omitted, and due to the fact that the suspension is of an independent suspension structure, the unsprung mass can be reduced to a large extent, so the system is simplified, the assembly weight is reduced, the light-weight target is achieved, and the whole vehicle control stability and smoothness are greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an independent suspension integrated wheel motor assembly. Background technique [0002] In recent years, in the technical field of electric vehicles, the drive mode of the wheel motor has received extensive attention. The drive motor is integrated into the wheel, which is different from the drive mode of the traditional mechanical transmission vehicle. The vehicle driven by the wheel motor is powered by a battery or power The unit generates electricity, and transmits the electricity to the wheel side motor device located in the wheel for direct drive. The wheel side motors are generally arranged symmetrically, with equal numbers on the left and right sides. This symmetrical arrangement can realize the stability control of the vehicle and the coordinated control of the dynamics of the whole vehicle through the distribution of the longitudinal force of the two dri...

Problems solved by technology

In the existing technical solutions, the motor is mostly arranged on the steering knuckle, and the motor is fixed to the steering knuckle through the flange. Since the motor will have a great impact when the wheel jumps, the shock absorption and buffering of the motor must be considered. This increases the complexity and cost of the suspension structure. At the same time, when the vehicle is driving on a poor road surface, due to the large impact, it will greatly affect the service life of the motor.
