Title:
VEHICLE TRANSMISSION DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/196592
Kind Code:
A1
Abstract:
A vehicle transmission differential device, comprising a power disc (1) which is provided with, not at the center thereof, a drive bearing (4), the drive bearing (4) is connected to a drive shaft (5), the other side of the drive shaft (5) is connected to a drive universal joint (6), a universal joint bearing (7) is mounted on the drive universal joint (6), and the drive universal joint (6) is connected to an output shaft (9). When an engine does not provide power and the power disc (1) does not move and a vehicle maintains itself in a traveling state under the action of inertia, vehicle wheels drive the output shaft (9) to rotate, and enable the drive shaft (5) to rotate about its own center A-A by means of the drive universal joint (6). When the engine provides power and the power disc (1) drives the drive shaft (5) to perform revolution about a line B-B connecting the center of the power disc (1) and the center of the universal joint bearing (7), the rotation and the revolution of the drive shaft (5) are superimposed, such that the rotation speed of the output shaft (9) is increased; due to the increasing of the rotation speed of the output shaft (9), the speed of the vehicle and the rotation speed of the drive shaft (5) are also increased relatively; the rotation and the revolution of the drive shaft (5) are re-superimposed; the rotation speed of the output shaft (9) is re-increased, and the power disc (1) rotates at a certain rotation speed; and the rotation speed of the output shaft (9) and the speed of the vehicle can become even faster, such that the purpose of change in speed is achieved.
