Problems solved by technology

[0002] In the existing electric vehicles directly driven by motors, according to the driving conditions of the vehicles, the motors can change the speed in real time within the range of 0 rpm to several thousand rpms. This driving method makes the current reach 50A when the vehicle is running normally. Left and right, the current is higher when starting, which is 2-5 times that of normal driving, as high as 100A-250A, so the power system starting with high current consumes a lot of energy, and the remaining batteries of electric vehicles have long charging time and low cruising range As a result, electric vehicles cannot drive on highways like mechanically powered vehicles

Embodiment 1

[0014] combine figure 1 As shown, an automobile drive system with a motor rotating at a constant speed includes a power supply system 1, a motor 2, a clutch 3, a transmission 4, and a differential 61 arranged in sequence. It rotates at a constant speed at a high speed of 1000 rpm; the clutch 3 is reversely clutched, that is, when the clutch pedal is stepped on, the motor 2 is combined with the transmission 4, and the power is transmitted to the vehicle drive system; when the clutch pedal is released, the motor 2 and the transmission The transmission 4 is separated, and the power generation system 7 is used to convert the kinetic energy into power generation energy, which is fed back to the storage battery in the power supply system 1 for electricity storage. Speed ​​changer 4 further connects clutch 5, differential gear 61 and automobile rear axle 62, and then drives automobile to travel, can also be provided with a 90 ° steering transmission mechanism 5 between speed changer ...

Embodiment 2

[0018] combine figure 2 As shown, an automobile drive system with a motor rotating at a constant speed includes a power supply system 1, a motor 2, a clutch 3, a transmission 4, and a differential 61 arranged in sequence. It rotates at a constant speed at a high speed of 1000 rpm; the clutch 3 is reversely clutched, and when the clutch pedal is stepped on, the motor 2 is combined with the transmission 4 to transmit power to the vehicle drive system; when the clutch pedal is released, the motor 2 is connected to the transmission 4 is separated, and the kinetic energy is converted into power generation energy by the power generation system 7, which is reversely supplied to the storage battery in the power supply system 1 for electricity storage. Speed ​​changer 4 further connects clutch 5, differential gear 61 and automobile rear axle 62, and then drives automobile to travel, can also be provided with a 90 ° steering transmission mechanism 5 between speed changer 4 and differen...

Abstract

The invention provides an automobile driving system with a motor rotating at a constant speed. The automobile driving system comprises a power supply system, the motor, a clutch, a transmission and a differential mechanism which are arranged sequentially, wherein the motor rotates at the constant speed of 1000 revolutions per minute in a running period of an automobile; the clutch performs reverse separation and reunion; when a pedal of the clutch is pushed down, the motor is combined with the transmission, and power is transmitted to the automobile driving system; and when the pedal of the clutch is released, the motor is separated from the transmission, kinetic energy is converted into electricity generation energy by using a generating system, and power is supplied to a storage battery in the power supply system and is stored. The driving mode of the automobile driving system with the motor rotating at the constant speed is different from the traditional automobile driving and speed changing mode, the motor rotates at a high and constant speed, an effect of reducing breakaway starting current and running current is achieved by reverse separation and reunion of the clutch, the kinetic energy is converted into the electricity generation power when load is light or the automobile is stopped, the power is supplied to the storage battery and is stored, the trip distance of the automobile is lengthened, and the purpose of saving energy is effectively achieved.

technical field [0001] The invention relates to the field of automobile power systems, in particular to an automobile drive system in which a motor rotates at a constant speed. Background technique [0002] In the existing electric vehicles directly driven by motors, according to the driving conditions of the vehicles, the motors can change the speed in real time within the range of 0 rpm to several thousand rpms. This kind of driving mode makes the current reach 50A when the vehicle is running normally. Left and right, the current is higher when starting, which is 2-5 times that of normal driving, as high as 100A-250A, so the power system starting with high current consumes a lot of energy, and the remaining batteries of electric vehicles have long charging time and low cruising range As a result, electric vehicles cannot drive on highways like mechanically powered vehicles. Contents of the invention [0003] The invention provides an automobile drive system in which the...
