Interaxial differential and transfer mechanism for twin-shaft gearbox and automobile with interaxial differential and transfer mechanism

Abstract

The invention discloses an interaxial differential and transfer mechanism for a twin-shaft gearbox and an automobile with the interaxial differential and transfer mechanism, belonging to the technical fields of differential and transfer of automobiles. The interaxial differential and transfer mechanism comprises two sets of planetary gear transmission mechanisms respectively connected to two ends of a driven shaft of the twin-shaft gearbox, wherein the driven shaft of the gearbox is a hollow shaft, one end of the driven shaft of the gearbox is connected with a planetary gear carrier of the first planetary gear transmission mechanism, and the other end of the driven shaft of the gearbox is connected with a gear ring of the second planetary gear transmission mechanism; a sun gear of the first planetary gear transmission mechanism is connected with a sun gear of the second planetary gear transmission mechanism through a differential transmission shaft penetrating through the middle of the driven shaft of the gearbox; a gear ring of the first planetary gear transmission mechanism is connected with a first power output shaft, and a planetary gear carrier of the second planetary gear transmission mechanism is connected with a second power output shaft. The interaxial differential and transfer mechanism has the advantages that the transmission efficiency is high, the stress of the driven shaft of the gearbox is small, and a large torque can be transferred.

Description

technical field [0001] The invention relates to a differential and transfer system of a four-wheel drive automobile, more specifically, to an inter-axle differential and transfer mechanism for a two-shaft gearbox and an automobile using the same. Background technique [0002] Four-wheel drive vehicles are divided into three types: full-time four-wheel drive, short-term four-wheel drive and timely four-wheel drive. Among them, full-time four-wheel drive can realize driving force on all four wheels at any time, and its performance is better than short-term four-wheel drive. Part-time four-wheel drive and part-time four-wheel drive. [0003] In order to realize full-time four-wheel drive, a transfer case and an interaxle differential must be installed on the car. Such as figure 1 As shown, one method is to integrate the transfer case and the inter-axle differential, the gearbox transmits power to the transfer case through gears or chains, and then the transfer case transmits ...
