Embodiment Construction

[0020] The self-adjusting electronic differential of the present invention, such as figure 1 As shown, the accelerator 3 is composed of an accelerator pedal 1, an accelerator pedal connecting rod 2 and an accelerator body. The accelerator signal line is divided into two inner and outer ones, which are respectively connected with the inner and outer drive motors 10 to control the operation of the motor. The inner and outer driving wheels 6 are respectively driven by the inner and outer driving wheel transmission shafts 7, and the inner and outer driving wheel transmission shafts 7 are connected with the universal sleeves 8 of the inner and outer driving wheel transmission shafts through tooth-shaped splines. The shaft of the universal sleeve 8 of the wheel transmission shaft is placed in the bearing 9 of the universal sleeve of the inner and outer drive wheel transmission shafts, and the shaft of the universal sleeve 8 of the inner and outer drive wheel transmission shafts is co...

Abstract

The invention relates to a self-regulating electronic differential mechanism which is an electronic control system of an electric car and is mainly applied to a dual-motor independent driving mode electric car. Two driving wheels are respectively driven by two motors directly. The driving motors are respectively controlled by two controllers with the same specification. The dual-motor independent and direct driving mode is realized and the self-regulating function of the electric differential is realized. The two controllers are controlled by an accelerator so that the two motors work under the same power and voltage. Due to the characteristics of the motors, the electric differential self-regulating function is realized through the regulation of different slipping rates and the flow limiting function of the controllers. As the driving torque of an internal driving wheel is larger than the external driving torque, therefore, different slipping rates appear and understeer is represented.
