A disconnected drive axle main reducer assembly

Abstract

The invention provides a disconnected type drive axle main reducer assembly. The main reducer assembly comprises a motor, an inter-shaft transitional case body, an inter-shaft transfer case body, a first transfer bevel gear, a second transfer bevel gear, a driving spiral bevel gear assembly and a driven spiral bevel gear assembly, wherein the motor is connected with the inter-shaft transfer case body through the inter-shaft transitional case body and used for transmitting power to the first transfer bevel gear and the second transfer bevel gear; one end of the inter-shaft transitional case body is connected with one end of the inter-shaft transfer case body through the first transfer bevel gear; the other end of the inter-shaft transitional case body is connected with the other end of the inter-shaft transfer case body through the second transfer bevel gear; the second transfer bevel gear transmits the power to the driving spiral bevel gear assembly; one end of the driving spiral bevel gear assembly is arranged inside the inter-shaft transfer case body, and the other end of the driving spiral bevel gear assembly is arranged inside a main reducer shell; the driven spiral bevel gear assembly is connected with a first suspension spider and a second suspension spider through bearings and used for transmitting the power to a first gear-side inner shaft assembly and a second gear-side inner shaft assembly. Thereby, the disconnected type drive axle main reducer assembly is great in carrying capacity and capable of satisfying all high performance requirements for a hybrid power chassis.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission, and in particular relates to a disconnected drive axle main reducer assembly. Background technique [0002] With the development of the automobile manufacturing industry, users have higher requirements for automobile mobility, reliability, concealment, economy and other performance. Although the current hybrid electric drive technology can solve many technical bottlenecks, for some specific types of vehicles, such as off-road vehicles, the hybrid electric drive technology still cannot meet the performance requirements of the off-road vehicle chassis. [0003] The existing hybrid electric drive technology generally uses the integrated electric drive axle main reducer as the core transmission assembly, and the electric drive axle is generally used on the chassis of an electric bus with a small load-carrying capacity. There are also some electric drive axle assemblies that are the i...
