Abstract

The invention discloses a pure electric loader transmission, and belongs to the technical field of transmissions. The transmission comprises two gears, is provided with a plurality of lubricating oil channels, effectively solves the problem of poor lubrication caused by a large height difference between input and output in the prior art, and is compact in structural arrangement. One end of an input shaft is connected with a power source, when the first gear is engaged, a gear shifting fork drives a sliding sleeve to move rightwards, power is transmitted to a first-gear toothed gear of a middle shaft through a first-gear toothed gear of the input shaft, then transmitted to an output shaft through an output toothed gear of the middle shaft and output through a flange plate, a second gear is engaged in the same way, and gear reversing is achieved by further utilizing the reversible characteristic of a motor. Compared with a traditional fuel oil system, the transmission has the advantages that energy-saving and emission-reducing effects are remarkable, and the transmission efficiency is greatly improved. The transmission disclosed by the invention can fully utilize the characteristics of a high efficiency interval and reversibility of the motor, cancels a reverse gear structure and reduces the number of gears, so that the transmission has the advantages of light weight and low cost.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and relates to a pure electric loader transmission. Background technique [0002] Loaders are mainly used for shoveling, loading, unloading, transporting soil and stones and other bulk materials. They are widely used in infrastructure, industrial applications and other fields, involving material handling, accumulation and paving. The working range is relatively fixed, and the working conditions relatively simple. The traditional fuel loader power system mostly uses the structure of "engine + pitch changer + power shift transmission", which has low transmission efficiency, many gears and complex structure, and serious pollutant emissions. [0003] In order to control the emission of pollutants from non-road diesel mobile machinery, the structural scheme control system of dual-motor direct drive and double-axle is relatively complicated. The loader with the existing "motor + power shift tran...
