Embodiment 1

[0034] Example 1: See Figure 1-6 , a dual-motor power synthesis device for driving an electric vehicle, comprising a front pole 1 and a front wheel 2, two groups of front wheels 2 are fixedly connected to both sides of the front pole 1, and a rear pole 7 is arranged on the top of the front pole 1, Two groups of rear wheels 6 are fixedly connected to both sides of the rear bar 7, two groups of connecting rods 11 are fixedly connected between the front rod 1 and the rear rod 7, and one end of the connecting rod 11 is fixedly connected to a shell 17, the top of the shell 17 and the The bottom end is fixedly connected with a heat dissipation mechanism 8, and the bottom end inside the casing 17 is provided with an energy-saving structure 10, and four sets of fixing pieces 13 are arranged on both sides of the top and bottom of the casing 17, and two sets of fixing pieces 13 are fixedly connected on both sides of one end of the fixing piece 13. Bolts 14, wear-reducing structures 16 ...

Embodiment 2

[0036] Embodiment 2: Four sets of fixing pieces 13 are arranged on both sides of the top and bottom of the housing 17; the fixing bolts 14 penetrate one end of the fixing piece 13 and are fixedly connected with the connecting rod 11; specifically, as figure 1 and figure 2 As shown, the electric vehicle consumes a large amount of electric energy when in use, which increases the cost of use. When the vehicle does not need a large amount of electric energy to drive, it only needs to drive the variable speed motor 9 on one side, and the motor drives the first gear 5 to rotate. , the second gear 1001 that meshes with the first gear 5 also rotates, and then the second gear 1001 drives the gear on the other side to rotate to drive the vehicle to drive normally, which reduces energy consumption and saves a lot of electric energy. Reduced cost consumption.

Embodiment 3

[0037] Embodiment 3: the heat dissipation mechanism 8 is made up of a heat dissipation gasket 801, a heat dissipation box 802, a heat dissipation hole 803, a blade 804 and a heat dissipation net plate 805, and the heat dissipation gasket 801 is fixedly connected to the top and bottom of the shell 17, and the heat dissipation gasket 801 The top is fixedly connected with a heat dissipation mesh plate 805, and the top inside the housing 17 is fixedly connected with three groups of heat dissipation boxes 802. The bottom of the heat dissipation box 802 is provided with a heat dissipation hole 803, and the inside of the heat dissipation box 802 is fixedly connected with a blade 804. The model of the blade 804 for DP200A;

[0038] The heat dissipation mesh plate 805 and the heat dissipation gasket 801 are on the same level; specifically, as figure 1 and Figure 4 As shown, the device will generate a large amount of heat energy under high-intensity use. The temperature sensor install...

Abstract

The invention discloses a dual-motor power synthesis device for electric vehicle driving, and particularly relates to the technical field of electric vehicle transmission; the dual-motor power synthesis device comprises a front rod and front wheels, and two sides of the front rod are fixedly connected with two groups of front wheels. By arranging a caterpillar band, a first bearing, a first gear,variable-speed motors and a third gear, when the device is started, the variable-speed motors, the first gear and the third gear are used for driving the front wheels and rear wheels to roll, and whenspeed changing is needed, only the two sets of variable-speed motors need to be controlled to synchronously change the speed to a certain numerical value, and when speed changing and steering of a vehicle can be achieved, the steering function is achieved only by changing the variable-speed motors to generate different speeds and utilizing different speed differences on the two sides, the steering requirement can be met only by starting the variable-speed motor on the other side without starting the variable-speed motor on one side, the whole process can be completed only by controlling the motors, operation is simple and easy, and practicability is high. The problem that an existing double-motor synthesis device is inconvenient to change speed and steer is solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle transmission, in particular to a dual-motor power synthesis device for driving electric vehicles. Background technique [0002] With the development of science and technology, more and more motor vehicles are widely used, and the emission of vehicle exhaust has aggravated the deterioration of the environment. Now more and more attention is paid to the development of new energy electric vehicles. Electric vehicles have achieved zero fuel consumption, zero emissions, and effective To improve the problem of environmental pollution, the driving of electric vehicles requires the use of dual-motor power synthesis devices, and the existing dual-motor power synthesis devices still have some shortcomings that need to be improved. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: [000...
