Abstract
The utility model relates to a transmission system of an electric vehicle, which comprises motors, a transmission shaft and a differential mechanism. The motors include a first motor and a second motor which are connected with the transmission shaft respectively in a transmission manner, and the transmission shaft is connected with the differential mechanism in a transmission manner. The electric vehicle is driven by the two motors, when torsion during running of the electric vehicle is small, the electric vehicle can be driven by only one motor, and on the contrary, when the torsion during running of the electric vehicle is large, the electric vehicle can be driven by the two motors. Low-power motors can be used for the transmission system due to the two-motor structure, so that the transmission system is lower in cost and energy consumption and is suitable for transmission of the electric vehicle on the condition with different torsion.
Description
Technical field
The utility model relates to a kind of driving system of electronlmobil.
Background technology
Along with growth in the living standard, automobile has become the widely used vehicle.Existing automobile is fuel mostly with gasoline, and gasoline-fueled automobile not only has a large amount of exhaust emissionss and contaminated environment, and because the growing tension of the energy, the development new automobile has become inexorable trend.
It is little that electronlmobil has pollution, and power consumption is low to be waited a bit.One of electronlmobil key component is its power drive system, comes powered vehicle to go by a motor usually.Because starting, climbing, level road during automotive operation and the change in torque of running at high speed are bigger, single motor-driven is difficult to meet the demands.If the employing heavy-duty motor, not only cost is high, and energy consumption is big.
Summary of the invention
The purpose of the utility model provides a kind of cost lower to the problems referred to above exactly, and energy consumption is less and can adapt to the driving system of the electronlmobil of working under the different torque conditions.
The technical scheme that the utility model provides is: a kind of driving system of electronlmobil; Comprise motor, transmission shaft and diff; Said motor is made up of motor one and motor two, and motor one is in transmission connection with transmission shaft respectively with motor two, and transmission shaft and diff are in transmission connection.
The utility model drives running car owing to adopt said structure through double-motor, when the moment of torsion of automotive operation hour, can drive automotive operation by a machine operation; When the moment of torsion of automotive operation is big, can works simultaneously by two motors and drive automotive operation.Because adopt the double-motor structure, the motor of lower-wattage promptly can be used for realizing the utility model, this not only makes the utility model cost lower, and energy consumption is less and can adapt to the transmission of the electronlmobil of working under the different torque conditions.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1; The driving system of the utility model electronlmobil comprises motor 1,2, transmission shaft 3 and diff 4; Said motor is made up of motor 1 and motor 22; Motor 1 is in transmission connection with transmission shaft 3 respectively through transmission device 7 (like coupler) with motor 22, and transmission shaft 3 is in transmission connection with diff 4.Diff 4 driving cars wheel shafts 5 and wheel 6 runnings.
When the utility model uses, be installed on the automobile, drive running car through double-motor, when the moment of torsion of automotive operation hour, can control a machine operation through control system and drive automotive operation; When the moment of torsion of automotive operation is big, can controls two motors through control system and work simultaneously and drive automotive operation.Because adopt the double-motor structure, this not only makes the utility model cost lower, energy consumption is less and can adapt to the transmission of the electronlmobil of working under the different torque conditions.
