Problems solved by technology
However, in the existing transmission system, if the high-speed and low-speed transmission lines continue to follow after entering the reverse gear, since the two lines have different transmission ratios, the transmission system will be self-locked, which will cause the transmission system to malfunction.

The invention discloses a central driving type self-adaption electric driving system capable of preventing self-locking of tricycle backing. A first-layer transmission sleeve is rotatably mounted on atransmission shaft in a sleeving manner; a second-layer transmission sleeve is rotatably mounted on the first-layer transmission sleeve in a sleeving manner; a high-speed transmission sleeve and a low-speed transmission sleeve are rotatably mounted on the second-layer transmission sleeve in a sleeving manner; the mutually closed end parts of the high-speed transmission sleeve and the low-speed transmission sleeve are mounted on the inner hole of an output component; a first deceleration mechanism is arranged between the right end of the transmission shaft and the first-layer transmission sleeve; a second deceleration mechanism is arranged between the right end of the second-layer transmission sleeve and the low-speed transmission sleeve; a reverse gear is arranged in the second deceleration mechanism; a transitional sleeve is arranged at the left end of the high-speed transmission sleeve; a second overrun clutch is connected between the transitional sleeve and the high-speed transmission sleeve; and a cam clutch mechanism is mounted at the left end of the second-layer transmission sleeve for transmitting rotation of the first-layer transmission sleeve to the transitional sleeve orthe second-layer transmission sleeve. The central driving type self-adaption electric driving system can prevent self-locking of tricycle backing.
Description
technical field [0001] The invention belongs to the technical field of driving electric tricycles, and in particular relates to a centrally driven self-adaptive electric driving system capable of preventing reversing self-locking. Background technique [0002] In recent years, new energy vehicles have received more and more attention. As one of the differences from traditional internal combustion engine vehicles, the drive technology of new energy vehicles such as electric tricycles can adopt in-wheel motor technology. The biggest feature of this technology is that the power unit, transmission and speed change device are all assembled in the hub of the wheel, thereby simplifying the mechanical structure of the tricycle power system. [0003] Among them, the power device usually adopts electric drive; the transmission device mostly adopts the form of gear transmission; the speed change device is also generally realized by changing the transmission ratio of the gear; In addi...
