Description
Technical Field
The invention belongs to a vehicle power transmission system, and particularly relates to a three-speed driving system based on a double-rotating-arm framework.
Background
Compared with the traditional fuel vehicle, the pure electric vehicle has quite different differences in the aspect of a power system, except for an engine with a complex structure and an exhaust system occupying a large amount of space, the working range of the driving motor is wide and can even reach 15000rpm, and secondly, the motor can output very large torque at zero rotating speed, so that the industry has great dispute on whether the pure electric vehicle is provided with a two-gear or even multi-gear transmission. The original assumption for the model of the pure electric vehicle is the driving scheme of the motor and the second gear transmission, and then the speed reducer with a fixed speed ratio is forced to be adopted due to the quality problem of the transmission, but in order to achieve the power performance of the original driving scheme, the power of the motor can be increased only to achieve the same performance, and in addition, the battery also needs to increase the capacity to provide higher output power. Some advanced manufacturers give a warning to domestic automobile manufacturers in the case of failed attempts of two-gear boxes, and in addition, the driving scheme of the motor and the single-gear reducer also meets the performance requirement at the present stage, and the domestic automobile manufacturers basically and widely select the driving scheme of the motor and the single-gear reducer as an assembly scheme used by main automobile models in consideration of the complexity of the existing technology and cost control. However, the disadvantage of the single-gear speed reducer is very obvious, and mainly under the two conditions of heavy-load starting and highest speed per hour, the motor cannot work in a high-efficiency area, so that the overall efficiency of an electric driving system is too low, the current is too high, and the endurance mileage is reduced.
