Although this electric vehicle gear box achieves the switching of Motor torque, because complex structure weight is large, add motor load, gearbox-gear switches smooth and easy not simultaneously, and traveling is experienced poor.

Utility model content

The purpose of this utility model is the electric vehicle motor providing a kind of bi-motor structure, adopts high-speed electric expreess locomotive and slowspeed machine to match, and when starting, accelerating and climbing, height motor runs, jointly to increase power output and moment of torsion; Run at high speed and then driven by high-speed electric expreess locomotive list motor, and slowspeed machine is separated with reducing gear with output shaft by single clutch, reduce the efficiency of power consumption lifting motor, do not affect the normal operation of device, the utility model is monitored in real time by the running status of controller to motor of device, controls the operating state of two motors according to motor operating state, realize the electrodeless switching of Power output, have rational in infrastructure, easy and simple to handle, and greatly increase comfortableness.

For achieving the above object by the following technical solutions:

A kind of electric vehicle motor of bi-motor structure, it is characterized in that: comprise high-speed electric expreess locomotive, slowspeed machine and reducing gear, described slowspeed machine and high-speed electric expreess locomotive are distributed in the both sides of reducing gear, the output shaft of high-speed electric expreess locomotive and slowspeed machine is connected to the two ends of reducing gear input tooth axle, the rotor of described high-speed electric expreess locomotive directly and output shaft fixed connection, the rotor of described slowspeed machine is connected with output shaft by one-way clutch, and described high-speed electric expreess locomotive is all connected with the input of reducing gear with the output shaft of slowspeed machine.

The outside of described slowspeed machine and high-speed electric expreess locomotive housing all arranges end cap, the center of end cap is provided with the containing cavity of indent, the sidepiece of containing cavity has a breach, containing cavity internal fixtion Hall element, the Hall element of Hall element is corresponding with the rotor-position of motor through breach from indentation, there.

The utility model will by high-speed electric expreess locomotive and slowspeed machine cooperating, when starting, accelerating or climbing, bi-motor works to reach simultaneously and increases at power output and moment of torsion, and driven by high-speed electric expreess locomotive list motor when level road is run at high speed, energy saving increases endurance distance, the utility model is under the control of the controller of motor, follow and can automatically switch according to road conditions and transport condition, realize Power output without pole-change, have rational in infrastructure, easy and simple to handle, and greatly increase comfortableness.

Fig. 2 is the internal structure schematic diagram of the utility model two motor both sides distributions.

Embodiment

As shown in Figure 1-2, a kind of electric vehicle motor of bi-motor structure, comprise high-speed electric expreess locomotive 1, slowspeed machine 2 and reducing gear 3, described slowspeed machine 2 and high-speed electric expreess locomotive 1 are distributed in the both sides of reducing gear 3, the output shaft of high-speed electric expreess locomotive 1 and slowspeed machine 2 is connected to the two ends of reducing gear input tooth axle 31, the rotor of described high-speed electric expreess locomotive 1 directly and output shaft fixed connection, the rotor of described slowspeed machine 2 is connected with output shaft by one-way clutch 5, the outside of described slowspeed machine 2 and high-speed electric expreess locomotive 1 housing all arranges end cap 6, the center of end cap 6 is provided with the containing cavity 61 of indent, the sidepiece of containing cavity 61 has a breach 62, containing cavity 61 internal fixtion Hall element, the Hall element of Hall element is corresponding with the rotor-position of motor through breach from indentation, there.

Slowspeed machine has the high feature turned round of low speed, high-speed electric expreess locomotive is then the low feature turned round of high speed, high-speed electric expreess locomotive power consumptive province when running up, speed is fast, course continuation mileage can be increased, but high-speed electric expreess locomotive is in startup, when accelerating and climb, moment of torsion is not enough, there is the situation of difficulty in starting, and the intervention of slowspeed machine just in time overcomes these deficiencies of high-speed electric expreess locomotive, slowspeed machine is separated with output shaft by one-way clutch, the output of high-speed electric expreess locomotive is affected when avoiding static, the utility model realizes the electrodeless switching of Power output under the control of electric machine controller, have rational in infrastructure, easy and simple to handle, and greatly increase comfortableness.

The needs of high/low-speed motor bilateral symmetry distribution or mounting position of motor comparatively large mainly for some power, when power of motor is larger, two motors are installed in a housing simultaneously, make single motor bulky, be not easy to install, the distribution of cloth both sides is more conducive to the balance of both sides, and is conducive to the installation of heat radiation and motor.

Hall element is arranged the accommodating cavity of end cap central by the utility model in addition, and the Hall element of Hall element enters into motor internal from lateral notch, and this structure facilitates the replacing of Hall element.
