Problems solved by technology

[0003] When the current driving device for new energy vehicles brakes, the rotating shaft of the generator is usually directly connected to the drive shaft of the driving device of the car, so that the kinetic energy of the car is converted by the generator. However, this method makes the brake that the generator can play The effect is very fixed, and it is impossible to increase or reduce the deceleration effect of the generator on the vehicle according to the actual speed of the vehicle, thereby reducing the functionality of the drive device; and the current drive device for new energy vehicles often produces a large number of If the heat cannot be dissipated in time, it may affect the use effect of the new energy vehicle driving device; at the same time, the current new energy vehicle driving device usually uses the generator and the brake device at the wheel to control the speed of the car , the brake deceleration effect of the new energy vehicle cannot be further improved when the vehicle is running at high speed, thus reducing the safety of the driving device for the new energy vehicle

Embodiment 1

[0034] Example 1, such as Figure 1-4 As shown, when the driving device for the new energy vehicle needs to be braked at a low speed, after the driver of the vehicle lightly steps on the foot brake, the first group of electric pneumatic cylinders 906 are controlled through the console of the vehicle to push a group of U-shaped frames 904, so that The second transmission gear 905 meshes with the first large gear 901 and the second small gear 17 respectively, thereby driving the rotating shaft of the generator 14 to rotate, and while reducing the speed of the first drive shaft 5, the generator 14 is also used to generate electricity, and through the inverter The converter 8 converts the electricity generated by the generator 14 and then transfers it to the storage battery of the automobile.

Embodiment 2

[0035] Example 2, such as Figure 1-3 As shown, when the driving device for the new energy vehicle normally drives the vehicle, the driving motor 13 drives the fan 15 on the rotating rod 12 to rotate through the cooperation of the first connecting gear 19 and the second connecting gear 20, so that the main body box 1 The air with heat inside is blown into the inside of the connecting chamber 7, part of the heat of the hot air is absorbed by the second heat conducting rod 6 and dissipated to the outside, and when the hot air passes through the heat exchange tube 202, a large amount of heat is stored The coolant inside the water tank 204 is absorbed, and then the cooled air is blown into the inside of the installation chamber 3, and the inverter 8 is blown to cool down and then flows back into the inside of the main box 1, and the driving motor inside the main box 1 13 and the generator 14 carry out wind cooling to form air circulation flow, and part of the heat inside the main ...

Embodiment 3

[0036] Example 3, such as figure 1 , 2 , 3, 4 and 6, when the driving device of the new energy vehicle needs to brake at high speed, the driver will step on the foot brake to the bottom, so as to control the second group of electric pneumatic cylinders 906 to extend to the maximum through the console of the car. Long, so that the first transmission gear 903 meshes with the first small gear 902 and the second large gear 18 respectively, driving the second drive shaft 11 to rotate, while the first group of electro-pneumatic cylinders 906 is shortened, and the second transmission gear 905 is no longer in contact with the second transmission gear 905. The large gear 901 meshes with the second small gear 17. Since the gear diameter of the second large gear 18 is larger than that of the first small gear 902, the speed of the second drive shaft 11 will be further increased, and the speed of the rotating shaft of the generator 14 will be increased. When the generator 14 produces more...

Abstract

The invention discloses a driving device for an energy-saving new energy vehicle, which comprises a main body box, an installation warehouse is installed at one end of the top of the main body box, and a cooling mechanism is installed at the other end of the top of the main body box, and the main body box is far away from the installation warehouse A connecting warehouse is installed at one end of the connecting warehouse, and a second heat-conducting rod is evenly installed inside the connecting warehouse, and the end of the second heat-conducting rod away from the main body box extends to the outside of the connecting warehouse, and a sieve plate is installed at the bottom of the installation warehouse. And the inverter is installed on the top of the sieve plate. The present invention is used through the cooperation of the main body box, the installation warehouse, the first drive shaft, the inverter, the adjustment speed reduction component, the sieve plate, the second drive shaft, the drive motor, the generator, the second large gear and the second small gear, The control effect of the driving device for the new energy vehicle on the speed of the vehicle is improved, and the electricity generated by the generator can also be used to charge the storage battery of the vehicle, thereby improving the energy saving effect of the driving device for the new energy vehicle.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an energy-saving driving device for new energy vehicles. Background technique [0002] With the increasingly prominent environmental protection issues such as climate warming, new energy vehicles represented by electric vehicles have become an important development direction of future vehicles. Electric vehicles use vehicle-mounted DC power supply (rechargeable battery) The DC power of the on-board DC power supply is converted into AC power and supplied to the motor, and the rotor shaft of the motor transmits power to the gearbox to drive the wheels. [0003] When the current driving device for new energy vehicles brakes, the rotating shaft of the generator is usually directly connected to the drive shaft of the driving device of the car, so that the kinetic energy of the car is converted by the generator. However, this method makes the brake that the generator can pl...
