Embodiment Construction

[0011] exist figure 1 In the shown embodiment, the dual transmission gear (3), the reverse dial (5), and the reverse main gear (6) are installed on the power input shaft (1) in sequence, and the dual transmission gear (3) and the reverse gear The main gear (6) can rotate freely on the power input shaft (1), and the reverse gear dial (5) has internal spline teeth that mesh with the spline teeth on the power input shaft (1) and can be rotated in reverse gear. The shifting fork (4) slides axially down. The low-speed gear (7), the shift dial (9), the high-speed gear (10), and the reverse pinion gear (11) are installed on the power output shaft (2) in sequence, and the low-speed gear (7) and the high-speed gear (10) The output shaft (2) can rotate freely, and there are internal spline teeth on the speed change dial (9) meshing with the spline teeth on the power output shaft (2) and can be moved by the speed change fork (8). Axial sliding. The reverse gear pinion (11) is fastened...

Abstract

The invention provides a speed changing box. A power inlet shaft, a power output shaft and an idler shaft are arranged in the speed changing box; a duplex change gear, a speed changing starwheel, a high-speed gear, a low-speed gear, a reverse-gear master gear, a reverse-gear starwheel and a reverse-gear auxiliary gear are arranged on the power inlet shaft and the power output shaft according to power transmitting sequence; an idle wheel is arranged on the idler shaft; a reverse-gear shifting fork controls the reverse-gear starwheel capable of sliding in the axial direction to slide between the duplex change gear and the reverse-gear master gear so as to switch a forward gear or a backward gear; and a speed changing shifting fork controls the speed changing starwheel capable of sliding in the axial direction to slide between the high-speed gear and the low-speed gear or between a big gear wheel and a pinion on the duplex change gear so as to switch a high-speed gear or a low-speed gear of the forward gear. With adoption of the speed changing box, a motorized tricycle or four-wheeler adopting a stepless speed change engine has the reverse-gear function and is simple and easy to drive; and with adoption of the motorized tricycle or four-wheeler with a geared engine, the structure is simpler and compacter, and the maintenance is simple and convenient.

Description

technical field [0001] The invention relates to a transmission for a vehicle, especially an auxiliary transmission with a reverse gear function for a motor tricycle or a four-wheel vehicle. Background technique [0002] At present, most of the known motorized tricycles or four-wheeled vehicles use engines with gearshift levers. Some elderly people or women are difficult to learn and master the skills of shifting gears during use. , fuel consumption increases; or use high-speed gears for the whole journey, the power is insufficient, easy to stall, and the engine wears seriously. There are a small number of motor tricycles or four-wheel vehicles to use the continuously variable speed engine, which solves the above problems, but the reverse gear function cannot be provided, which affects the ease of use of the three-wheel vehicle or four-wheel vehicles. [0003] In addition, because most of the currently known motor tricycles or four-wheeled vehicles use engines with gear shif...
