Abstract
The invention relates to a motor drive system of a pure electric vehicle. The motor drive system is characterized by comprising a drive motor, a speed reducer, a motor controller, a radiator and a water pump; and the output power of the drive motor is controlled by the motor controller, a bracket for connection of the drive motor and the speed reducer is suspended at the lower end of a front compartment of a vehicle body, a liquid-cooled drive motor is adopted as the drive motor, and coolant of the drive motor flows through a heat-dissipating circulation system formed by the radiator and the water pump. The motor drive system of the pure electric vehicle has the beneficial effects that the problem of heat dissipation of the drive motor during high-speed driving can be well solved, the motor can be maintained at a stable and reasonable temperature, and the service life of the drive motor can be prolonged effectively.
Description
Technical field
The present invention relates to a kind of drive system of automobile, particularly a kind of motor driven systems of pure electric automobile.
Background technology
Along with the transition in epoch, the appearance of combustion engine is widely used in auto trade.Auto-industry have become the capable industry of pillar of development of world economy.Yet the continuous growth of the recoverable amount of internal-combustion engines vehicle, combustion engine also becomes increasingly conspicuous to the problem that the mankind bring.Embody a concentrated expression of on the problem of problem of environmental pollution and oil resources shortage.In order to reduce the continuation aggravation of this type of crisis.The technology that the core position combustion engine of auto-industry need to upgrade replaces.Seek the vehicle of anti-emission carburetor even " zero " discharging.The standby undoubtedly vertex of having shifted onto of electronlmobil.
Pure electric automobile adopts motor-driven usually, and drive motor is used on the electronlmobil, because long-time high-frequency operation, the temperature of motor is very high, and traditional air-cooled of single use is that the motor that can not satisfy electronlmobil requires.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of drive motor that can solve in the pure electric automobile motor drive system of the heat dissipation problem of long-time high-frequency operation.
Technical scheme: a kind of pure electric automobile motor drive system is characterized in that: comprise drive motor, retarder, electric machine controller, radiator and water pump; The horsepower output of described drive motor is by motor controller controls, described drive motor is connected with support with retarder and is suspended on the automobile body fore-cabin lower end, described drive motor adopts the liquid cooling drive motor, the heat dissipation circulating system that the refrigerant fluid of drive motor forms by radiator and water pump.The present invention can directly reequip on the basis of traditional vehicle body, and uses the radiator of orthodox car, has improved the commonality of electronlmobil and orthodox car parts.
Beneficial effect: the present invention can solve the heat dissipation problem of drive motor in the process of running at high speed makes one of motor maintenance stablize rational temperature, has effectively improved the service life of drive motor.
The specific embodiment
A kind of pure electric automobile motor drive system is characterized in that: comprise drive motor, retarder, electric machine controller, radiator and water pump; The horsepower output of described drive motor is by motor controller controls, described drive motor is connected with support with retarder and is suspended on the automobile body fore-cabin lower end, described drive motor adopts the liquid cooling drive motor, the heat dissipation circulating system that the refrigerant fluid of drive motor forms by radiator and water pump.The present invention can directly reequip on the basis of traditional vehicle body, and uses the radiator of orthodox car, has improved the commonality of electronlmobil and orthodox car parts.
The present invention can solve the heat dissipation problem of drive motor in the process of running at high speed makes one of motor maintenance stablize rational temperature, has effectively improved the service life of drive motor.
