Intelligent power driving device for new energy vehicle

Abstract

The invention relates to an intelligent power driving device for new energy vehicle. The intelligent power driving device comprises a direction inductor, a vehicle chassis, a central controller and a lifting transmission wheel; a steering wheel is arranged above the direction inductor; the direction inductor is mounted on the left side in front of the vehicle chassis; a lithium ion battery is mounted in the center of the vehicle chassis; the direction inductor is connected with the central controller; the central controller is connected with a wheel driving motor; a motor controller is mounted behind the wheel driving motor; a signal cable extends out of the motor controller; a motor driving gear is mounted on an output shaft of the wheel driving motor; and the lifting transmission wheel is mounted on the side surface of the motor driving gear, and is connected to a hub driving gear. The intelligent power driving device for the new energy vehicle has the following beneficial effects: the wheel steering is controlled through the direction inductor, so that the sensitivity is higher, and the wear is lower; and each motor controls one wheel, so that the vehicle horsepower is improved.

Description

technical field [0001] The invention relates to the field of new energy vehicle design, in particular to an intelligent power drive device for new energy vehicles. Background technique [0002] The composition of new energy electric vehicles includes: electric drive and control systems, mechanical systems such as drive force transmission, and working devices to complete established tasks. The electric drive and control system is the core of electric vehicles, and it is also the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. The rest of the equipment of electric vehicles is basically the same as that of internal combustion engine vehicles. The function of the drive motor is to convert the electrical energy of the power supply into mechanical energy, and drive the wheels and working devices through the transmission or directly. At present,...

However, due to the existence of commutation sparks in DC motors, the power is small, the efficiency is low, and the maintenance workload is large; with the development of motor control technology, it is bound to be gradually replaced by DC brushless motors, switched reluctance motors and AC asynchronous motors, but still Relying on the traditional steering mechanism system, the wear is relatively serious, and the degree of intelligence is not high
