The present invention adopts a water-cooled motor, a power tube IPM (or IGBT) and a control circuit board are arranged on a water jacket of the motor, and thus, the motor and an electric control device forms a whole electromechanical integration type power unit. The present invention can achieve the purposes of weight lightening, volume reduction, structure simplification and energy consumption reduction. The present invention can be used for various electric automobiles.
Description
Technical field
The present invention relates to the improvement and the raising of power unit of electric car
Background technology
Electronlmobil is paid close attention to by the personage of every aspect deeply as a kind of pollution-free back environmental type automobile, many in the world countries all develop sparing no effort.With regard to the problem of current discovery, the key of battery-driven car is energy mix, and existing battery technology deficiency is so that the chemical power of the storage electric energy of storage battery and automobile is comparable, and its difference reaches two orders of magnitude.This just makes the electronlmobil difficult problem that becomes international, and is difficult to enter commercial operation.How to reduce the energy consumption of electronlmobil, also just become the key that battery-driven car is developed.
In the development of electronlmobil, drive motor and control setup generally all are to be provided with respectively as independent device separately, motor is fixedly on the car vehicle body or in the wheel hub, it is fixing separately that controller then is made into a control box specially, overheated in order to prevent power tube IGBT or IPM, also need to be provided with radiator and special-purpose radiator fan.The way that this motor and controller are provided with respectively, no doubt have and establish one's own system and advantage that the phase mutual interference is few, but also exist bigger defective: 1, electronlmobil is the tool movement of a moveable type, its available space is most valuable, for small passenger car, situation is all the more so, and drive motor is provided with respectively with control four, must strengthen and take up room, this general design to battery-driven car is disadvantageous; 2, increased non-actv. weight, as radiator in the controller and special-purpose radiator fan; 3, increased energy consumption, not only radiator fan needs consumed power, and controller and motor are placed respectively, has strengthened the loss of connection line.
Summary of the invention:
The objective of the invention is improvement by motor and actuator, in the hope of reducing the weight of motor and actuator, minimizing takes up room, impel the lightweight of motor and actuator, miniaturization improves energy utilization, cut down the consumption of energy, improve the dynamic property of battery-driven car,, improve necessary condition for electronlmobil enters commercial operation.
The present invention solves the technical scheme that its technical matters is taked:
1, drive motor adopts water cooled machine, the shell of motor is exactly a cooling-water chamber, and the inner chamber of water jacket is cylindrical shape or anistree cylindricality, in order to the stator of device motor, the outer wall of water jacket is rectangle or octagonal cylindrical shell, in order to rating of set pipe IPM or IGBT and other control circuit board.
2, temperature controller is set in cooling-water chamber, and link to each other with coolant storage tank and radiator, difference according to water temperature, adopt the mode of gravity circulation or forced circulation respectively, the rate of circulation of control cooling water expansion tank, the temperature of water jacket is controlled in 85 ℃ all the time, and retentive control device and motor are worked in the range of temperatures of permission.
The invention has the beneficial effects as follows:
1, drive motor links to each other with its controller, and the power unit that is combined as a whole, controller no longer need special-purpose radiator and fan are set, and can reduce effectively to take up room and weight of equipment.
2, drive motor adopts water-cooled, can improve the electric current of motor, reduces the weight and volume of motor effectively.
3, motor and controller are combined as a whole, and it is the shortest that line between the two can reduce to, all can be highly beneficial to the maintenance in general layout and the use.
Description of drawings:
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the scheme drawing of power unit;
Among the figure: the 1-drive motor; 2-power tube IPM or IGBT; The 3-control circuit board; The 4-coolant outlet pipe; The 5-coolant inlet pipe; 6-control line plug; 7-power line plug; The 8-electric machine casing; Anistree cylindricality of 9-or rectangle water jacket; The 10-screened housing; The 11-temperature controller.
The specific embodiment:
Drive motor 1 adopts water-cooling pattern, octagonal column shape or rectangle water jacket 9 are set on a face of water jacket outside the shell 8 of motor, power tube IPM or IG BT 2 are installed, another face is provided with control circuit board 3, be the runner of cooling water expansion tank between the water sleeve motor housing, the joint of water inlet pipe and water outlet pipe 5,4 is set in the termination of motor, cooling water expansion tank can pass through water inlet pipe and water outlet pipe, in the water channel around the motor casing, flow, the heat that produces in motor and the power tube working process is taken away.Also just no longer need to be provided with radiator and radiator fan.On water jacket, also be provided with temperature controller 11, can adopt the mode of gravity circulation and forced circulation respectively, use by the flow control motor of cooling water expansion tank and the temperature of power tube according to the water temperature difference.Because motor 1 power tube IPM or IGBT 2 and control circuit board 3 all are set together, it is the shortest that mutual connection line can reduce to, external circuits is also very succinct, introduce power by power line plug 7, by control line plug 6 signal is imported or sent, outside IPM and control circuit board, metallic shield 10 is set, in order to prevent wave interference, power line plug 7 and control line plug 6 all install on screened housing.
