一种基于轮毂直驱电机的电动汽车悬架系统Electric vehicle suspension system based on hub direct drive motor 技术领域Technical field
本发明涉及新能源汽车技术领域，尤其涉及一种基于轮毂直驱电机的电动汽车悬架系统。The invention relates to the technical field of new energy vehicles, in particular to an electric vehicle suspension system based on a direct drive motor of a hub.
背景技术Background technique
当前，随着能源短缺和空气污染的日趋严重，世界上很多国家都在大力发展节能、环保的电动汽车。伴随着电动汽车的迅速发展，各种电动汽车的电机也种类繁多，且装配方式也多种多样。当前大部分电动汽车的电机都是内转子电机，且为前轮驱动，并且安装在车辆的前舱内，而采用后轮直驱动力系统的较为少见。随着技术的发展，目前国内外已经有比较好的轮毂直驱电机，可直接装配在汽车的轮毂中，可以省去减速器、变速器、差速器等附件，减少电机动力在传递过程中的损失，从而减少车辆生产的成本。然而，现有的电动汽车都是沿用传统燃油汽车的悬架系统，主要分为非独立悬架和独立悬架两种，都不适合现有的轮毂电机的安装使用。目前还没有一种悬架系统，适用这种轮毂直驱电机的安装使用。At present, with the shortage of energy and air pollution, many countries in the world are vigorously developing energy-saving and environmentally-friendly electric vehicles. Along with the rapid development of electric vehicles, various electric vehicles have a wide variety of motors and various assembly methods. Most of the electric motors in the current electric vehicles are inner rotor motors, which are driven by the front wheels and are installed in the front compartment of the vehicle, and the rear wheel direct drive system is relatively rare. With the development of technology, there are already better wheel drive direct drive motors at home and abroad, which can be directly assembled in the wheel hub of the car, which can eliminate the accessories such as reducer, transmission and differential, and reduce the motor power in the process of transmission. Loss, thereby reducing the cost of vehicle production. However, the existing electric vehicles are suspension systems of conventional fuel vehicles, and are mainly divided into non-independent suspensions and independent suspensions, which are not suitable for the installation of existing hub motors. There is currently no suspension system for the installation and use of such a direct drive motor.
另外英国专利申请(GB 247989A)公开的轮毂电驱系统的结构，虽然可安装在现有传统的悬架结构上。但是结构复杂，并且刹车系统直接集成在轮毂电机旁，刹车时刹车片所产生的高温会迅速的传导到电机的本体上，造成电机中的永磁体受到高温的影响会产生退磁的现象，导致电机的性能下降，使用寿命缩短。In addition, the structure of the hub electric drive system disclosed in the British Patent Application (GB 247989A), although it can be installed on existing conventional suspension structures. However, the structure is complicated, and the brake system is directly integrated beside the hub motor. The high temperature generated by the brake pads during braking can be quickly transmitted to the body of the motor, causing the permanent magnet in the motor to be demagnetized due to the high temperature, resulting in the motor. The performance is degraded and the service life is shortened.
