Synchronous two-stage transmission for vehicle

Abstract

The invention provides a synchronous two-stage transmission for a vehicle. The synchronous two-stage transmission comprises an input spline shaft and an output angle gear shaft, wherein the input end of the input spline shaft is arranged on the outer side of a box; an input connecting disk is arranged at the input end of the input spline shaft; a gear hub is arranged on the outer side of the spline part on the input spline shaft; a gear sleeve is arranged on the outer side of the gear hub; the gear sleeve is turned by a shifting fork to be moved; synchronous rings are arranged on the outer sides of the gear hub and the gear sleeve; the contact surfaces of the synchronous rings are slopes; a top-gear driving gear and a low-gear driving gear respectively sleeve the two sides of the input spline shaft idly; the opposite end faces of the top-gear driving gear and the low-gear driving gear are respectively meshed with the gear hub; the top-gear driving gear is externally meshed with a high-speed driven gear; the high-speed driven gear is fixed on the angle gear shaft; the low-gear driving gear is externally meshed with a low-speed driven gear; the low-speed driven gear is fixed on the angle gear shaft; the angle gear shaft is parallel to the input spline shaft; an angle gear is arranged at the upper end of the angle gear shaft; the upper end of the angle gear shaft extends to the outer side of the box. The power is inputted by the input spline shaft, then shifts the gear through the synchronizer, and then is transmitted to the output angle gear shaft through two approaches, so as to realize two types of transmission of the tricycle.

Description

technical field [0001] The invention relates to a tricycle, in particular to a transmission for the tricycle. Background technique [0002] Tricycle, a bicycle with three wheels, equipped with a carriage or a flat panel, used to carry people or load goods, a tricycle is a means of transportation transformed from a bicycle, which can carry people and goods, and was very popular after the 1930s , Gradually replaced the status of rickshaws. A tricycle looks like a combination of a rickshaw and a bicycle. [0003] Nowadays, the drive of the tricycle has adopted electric or motorized drive, the price is reasonable, and it is widely used in short-distance transportation or agricultural use. [0004] The electric tricycle adopts high-quality and large-capacity lead-acid battery for traction, which is powerful; it adopts high-quality DC motor, which has low operating noise and long service life; the speed regulation system adopts stepless speed regulation, which is simple in struc...

Problems solved by technology

[0005] As an important part of vehicle transmission, the transmission controls the speed of the vehicle. There are two types of transmission oil used in existing tricycles, one for fourth gear and one for fifth gear. There is no synchronizer on the transmission, so it must be accelerated slowly, and When shifting gears, the impact is large and unstable
