Abstract

The invention provides a vehicle two-stage transmission main reducer assembly. The vehicle two-stage transmission main reducer assembly comprises an input shaft, wherein the input shaft passes through a box and extends into the box; a bevel gear is arranged at the end, extending into the box, of the input shaft; the bevel gear is meshed with a main driven gear; the main driven gear is fixedly arranged on a driven shaft; a gear hub and a gear sleeve are fixedly arranged on the driven shaft; the gear sleeve can be driven by a shifting fork to move left and right; a high-speed driving gear and a low-speed driving gear are respectively arranged on two sides of the gear sleeve; the gear sleeve is respectively meshed with the end faces of the high-speed driving gear and the low-speed driving gear; the driven shaft is sleeved by the high-speed driving gear and the low-speed driving gear idly; the high-speed driving gear is meshed with a high-speed driven gear; the low-speed driving gear is meshed with a low-speed driven gear; the high-speed driving gear and the low-speed driven gear are respectively connected with a differential mechanism; two independent half shafts are arranged on the two sides of the differential mechanism respectively. The vehicle two-stage transmission main reducer assembly implements the deceleration function through the bevel gear and the main driven gear, and implements the transmission function of the reducer through the high-speed gear and the low-speed gear.

Description

technical field [0001] The invention relates to a speed reducer for a tricycle, in particular to a speed reducer for a tricycle with a shifting function. Background technique [0002] The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine, and its purpose is to reduce the speed. The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio. [0003] In a tricycle, the reducer needs to...
