[0055] The first embodiment, please refer to Figure 1-4

[0056] The transmission device provided by this embodiment includes a low-power motor 101 and a high-power motor 102 ("large" and "small" here are relative, that is, the power of the small-power motor 101 is less than the power of the high-power motor 102), so Both the low-power motor 101 and the high-power motor 102 are connected with a first transmission shaft 103, the free ends of the two first transmission shafts 103 are provided with first coupling teeth 104, and the two first coupling teeth 104 are arranged opposite to each other; The power difference between the low-power motor 101 and the high-power motor 102 is large, so there is a large difference in structure. Although the two first transmission shafts 103 have the same name, the structure is also different. The specific structure is different from that of the low-power motor 101 and The motor output shaft of the high-power motor 102 is compatible.

[0067] For the second embodiment, please refer to Figure 5-7

[0068] The basic structure and principle of the transmission device provided in this embodiment and the technical effects produced are the same as those of the first embodiment. For a brief description, for the parts not mentioned in this embodiment, please refer to the corresponding content in the first embodiment.

[0069] The transmission device obtained through the above design can basically meet its normal use, but in the purpose of further improving its function, the designer has further improved the transmission device.

[0070] The transmission device provided in this embodiment is additionally provided with a protective device. The protective device includes a motor side plate 115 provided on the high-power motor 102 and an outer plate 116 provided on the low-power motor 101. The motor side plate 115 is There is a through hole that can pass through the first drive shaft 103; the high-power motor 102 is also she...

[0076] The third embodiment, please refer to Figure 8

[0077] The electric vehicle provided in this embodiment includes the transmission device described in the second embodiment. The basic structure and principle of the transmission device and the technical effects produced are the same as those in the second embodiment. For a brief description, parts not mentioned in this embodiment are , Please refer to the corresponding content in the second embodiment.

[0078] The output half shaft 111 of the transmission device in this electric vehicle is connected with a drive shaft 201, and the drive shaft 201 is connected with two driving wheels 202. The electric vehicle also includes two driven wheels 203. When the electric vehicle is in use, the transmission device can transmit power to the driving wheel 202, and the driving wheel 202 can drive the driven wheel 203 to rotate. Preferably, the driving wheel 202 is the front wheel of the electric vehicle, and the driven wheel 203 is the...

Abstract

The invention provides a transmission device and an electric automobile, and belongs to the automotive field. The transmission device comprises a low-power motor, a high-power motor, a shifting motor gear sleeve, a second transmission shaft and a third transmission shaft. The low-power motor and the high-power motor are each provided with a first transmission shaft. The shifting motor gear sleeve is matched with the first transmission shaft of the low-power motor or the first transmission shaft of the high-power motor, so that the power transmission can be achieved. The transmission device is applied to the electric automobile. According to the electric automobile with the transmission device, on one hand, the electric automobile can accelerate rapidly and run stably; on the other hand, the efficiency of an accumulator of the electric automobile can be improved, and the cruising ability of the electric automobile is enhanced.

Description

Technical field [0001] The invention relates to the field of automobiles, and in particular to a transmission device and an electric automobile. Background technique [0002] The car is a symbolic product of the development of human civilization and one of the indispensable tools of modern society. Nowadays, under the background of the gradual shortage of petroleum energy, more and more automobile manufacturers have begun to develop new energy vehicles. Electric vehicles are the most important and mainstream of these vehicles. [0003] An electric vehicle is powered by an on-board power source and drives wheels with electric motors. Due to its relatively small impact on the environment, its prospects are widely optimistic. Its working principle and process: battery-current-power regulator-electric motor-power transmission system-drive the car. [0004] Electric vehicles have a variety of states when driving, including low-speed driving, high-speed driving, flat roads, slope or mud...
