Abstract

The invention discloses a motor vehicle planetary gear differential steering and driving synthesis system and the application thereof. The system is composed of an automobile rear axle differential planetary gear train, a fixed reduction gear train and a planetary gear train of a plus mechanism, wherein a second central gear (20) of the rear axle differential planetary gear train and a second central gear (14) of the planetary gear train of the plus mechanism are fixedly connected with a second half axle (13) to be connected to a second wheel, a first central gear (24) of the rear axle differential planetary gear train is connected with a first wheel by a second half axle (25), a first half shell and a second half shell (2 and 4) of a rotating arm axle of the rear axle differential planetary gear train is fixedly connected with a first coupling gear (5), the speed reduction is carried out by fixing gears (5,6,7 and 8) of the fixed reduction gear train, and a second coupling gear (8) is fixedly connected with a first central gear (9) of the planetary gear train of the plus mechanism, thereby connecting the fixed reduction gear train and the planetary gear train of the plus mechanism. The motor vehicle planetary gear differential steering and driving synthesis system has the advantages of simple structure and wide application range.

Description

technical field [0001] The invention relates to a chassis drive axle technology of a motor vehicle, in particular to a steering and driving system of a motor vehicle that realizes steering by changing the speed of the left and right wheels of the driving wheel, specifically a planetary wheel differential steering and driving system for a motor vehicle Synthetic systems and their applications. Background technique [0002] At present, the steering drive devices of domestic crawler vehicles and their variant products mostly use clutch steering systems. When this steering system works, the turning radius of the vehicle is greater than or equal to the gauge of the vehicle, and the steering is realized by the slipping of the steering clutch. When turning, all the power is concentrated on one side of the vehicle, while the other side has no power. Therefore, the power loss is relatively large when turning. At the same time, the steering clutch type steering mechanism has the dis...
