Two-way gear drive automatic variable speed motor transmission mechanism for electric vehicles

Abstract

A two-direction gear drive automatic variable speed motor transmission mechanism of an electric vehicle is composed of a motor, a transmission, an intermediate assembly and a driven gear, wherein a reverse driving gear is installed on a motor shaft and is engaged with a reverse intermediate gear installed on the intermediate assembly; a transmission shaft is arranged in the center of the transmission; a front drive driving gear is installed on a driving plate spline of the transmission and engaged with a front drive intermediate gear; the reverse intermediate gear is provided with a reverse one-way drive device; a forwarding one-way drive device is installed on the front drive intermediate gear; an intermediate driven gear is engaged with the driven gear; the driven gear is provided with a differential package; and an inner spline sleeve of the differential package is matched with an electric vehicle rear axle spline.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a two-way gear-driven automatic variable speed motor transmission mechanism for electric vehicles. Background technique [0002] Known electric vehicle motors have wheel hub type and gear variable speed motors. The wheel hub motor is a one-to-one transmission, and the gear variable speed motor is a direct motor to drive the speed change mechanism. This transmission mode has the defect that the speed and torque are not variable. Using the existing motor to assemble an electric vehicle cannot realize the multi-fold increase in torque. Slope requirements, especially in some mountainous areas and load electric vehicle applications. [0003] As electric power, its energy cannot be compensated compared with fuel vehicles during operation, so system efficiency becomes a key indicator of electric power. Whether it is fuel or electric, it has the highest efficiency space, and designers u...

Problems solved by technology

[0005] Looking at the current status of electric vehicles in my country, since the end of the last century, electric vehicles have developed rapidly. From the beginning of two-wheel electric vehicles to today's electric vehicles, the number of electric vehicle users in China has reached 250 million. Expanded to the use of goods transportation and sales of agricultural products. Therefore, technicians have invested in the technical creation and research of bridge-driven two-way transmission mode automatic variable speed motors. The structural scheme of the mechanism, but this technology has the defect that it cannot meet the needs of electric vehicles running in reverse.
