Problems solved by technology

[0003] The layout of the traditional single intermediate shaft transmission mostly adopts the form that the intermediate shaft assembly is arranged directly below the input shaft and output shaft assembly. Although it is convenient to arrange power output equipment such as power take-offs, it also has some disadvantages: the intermediate shaft assembly is arranged on the When the input shaft and output shaft are directly below, the control device can only be installed directly above the output shaft assembly, so that the height of the transmission assembly is relatively

Abstract

The invention discloses a two-gear speed changer compact in structure. The two-gear speed changer comprises an input shaft, a first-shaft intermediate assembly, a second-gear intermediate shaft assembly, an output shaft assembly and a differential mechanism. Power of a drive motor is transmitted to a shell through the input shaft, and a first-gear intermediate shaft assembly and the second-gear intermediate shaft assembly are connected with the shell through a clutch structure at the corresponding gear and transmit power. A first-gear intermediate shaft gear and a first-gear gear of an outputshaft are constantly engaged, a second-gear intermediate shaft gear and a second-gear gear of the output shaft are constantly engaged, and power is transmitted at the corresponding gear. According tothe two-gear speed changer, no friction exists in the gear shifting process, few components are adopted, impact is weak in the gear shifting process, reliability is high, the output power and the mechanical performance can be improved, and various properties of electric vehicles are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmissions, and in particular relates to a structure of a two-speed intermediate shaft transmission and a gear shifting method thereof. Background technique [0002] As a new generation of transportation, electric vehicles have great advantages over traditional fuel vehicles in terms of energy saving, emission reduction, and building a green home. [0003] The layout of the traditional single intermediate shaft transmission mostly adopts the form that the intermediate shaft assembly is arranged directly below the input shaft and output shaft assembly. Although it is convenient to arrange power output equipment such as power take-offs, it also has some disadvantages: the intermediate shaft assembly is arranged on the When the input shaft and the output shaft are directly below, the control device can only be arranged directly above the output shaft assembly, so that the height of the transmissio...
