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.

Embodiment Construction
[0034] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0035] This embodiment takes the application of the intelligent transmission system on the rear axle of an electric tricycle as an example for illustration. Those skilled in the art can understand that this solution can be applied to low-speed electric vehicles or other similar electric drive vehicles without technical obstacles .
[0036] Such as Figures 1 to 4 As shown, a central drive type intelligent transmission system for vehicles, a differential 2 is arranged in the axle housing 1 of the rear axle of the tricycle, and a half shaft 3 is installed at both ends of the differential 2, and the ends of the half shaft 3 Wheel hubs 3a are installed on all parts, and the transmission shaft 11 in the drive module B is driven by a motor 10. The motor 10 is arranged on the right end of the transmission shaft 11, and the transmission shaft 11 is equipped with a f...

The invention discloses a center driven type intelligent transmission system for a vehicle. A differential mechanism is arranged in an axle housing, half shafts are mounted at two ends of the differential mechanism, wheel hubs are mounted on the end parts of the half shafts, a first layer transmission sleeve is rotatably mounted on a transmission shaft in a sleeving manner, and a high speed transmission sleeve, an output part and a low speed transmission sleeve are rotatably mounted on the first layer transmission sleeve in a sleeving manner. Two ends of the output part are fixedly connected to the high speed transmission sleeve and the low speed transmission sleeve, separately, and the output part is in power connection to the differential mechanism through a first decelerating mechanism,a second decelerating shaft is arranged between the first layer transmission sleeve at the right end and the low speed transmission sleeve, a reversing gear is movably arranged in a middle position of the second decelerating shaft in a sleeving manner, a reverse gear device capable of sliding left and right is arranged, an overrun clutch is arranged on the low speed transmission sleeve, the highspeed transmission sleeve is connected to an accelerating transmission sleeve through a self-locking-preventing sleeve at the left end, the self-locking-preventing sleeve is in sliding fit with the accelerating transmission sleeve, and a can separation and reunion mechanism is mounted on the transmission shaft at the left end.
Description
technical field [0001] The invention belongs to the technical field of vehicle drive, and in particular relates to a central drive type intelligent transmission system for vehicles. 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 driving technology of new energy vehicles such as electric tricycles and low-speed electric vehicles can adopt integrated electric drive technology. The biggest feature of this technology is that the power unit, transmission and transmission are assembled in the vehicle in an integrated manner, thereby simplifying the mechanical structure of the vehicle power system. [0003] Among them, the transmission device mostly adopts the form of gear transmission, and the speed change transmission is realized by changing the transmission ratio of the gear; however, for the application of the speed change device, excep...
