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.

Description

Vehicle speed differential device

The present invention relates to devices in which various vehicles change speed as needed and can perform limited slip differential.

At present, it is known that the vehicle shifting commonly used in the market is realized by changing the output ratio of the output and the input. However, the shifting of the shifting mechanism requires a shifting mechanism, requires a hydraulic device, an electronic device, and has a complicated mechanical structure.

The present invention provides a vehicle shifting differential device that does not require changing the output and input gear ratios for shifting to improve the above-mentioned disadvantages and to perform limited slip differential.

The invention is realized in this way, including a power disk, a power shaft, a transmission shaft, a ring gear, a transmission bearing, a transmission universal joint, a universal joint bearing, a fixed bearing seat, an output shaft, and a power universal joint. The power shaft is fixed at the center of the power disk, and the transmission bearing is not installed at the center of the power disk, and is connected through the transmission bearing and the transmission shaft. The other side of the transmission shaft is connected to the transmission universal joint, and the universal joint bearing is provided on the transmission universal joint. And installed in the fixed bearing housing, the output universal shaft is connected to the transmission universal joint. It is also possible to mount a power disk universal joint between the power disk and the drive shaft.

In order to carry out the shifting and the limited slip differential, the two power disks of the above-mentioned device are connected together through a ring gear, and the respective transmission shafts, transmission universal joints and output shafts of the two power disks are connected through the universal direction. The joint bearings pass through the center of the power disk opposite each other and are then output through two fixed bearing blocks.

Figure 4 is an assembled view of a power disk universal joint using the present invention.

Figure 5 is a structural view of the two devices of Figure 1 combined with a ring gear according to the present invention;

This will be further explained below with reference to the drawings.

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, 1 power disk, 2 power shaft, 3 ring gear, 4 drive bearing, 5 drive shaft, 6 drive universal joint, 70,000 joint bearing, 8 Fixed bearing housing, 9 output shaft, 10 power disc universal joint, AA is the transmission shaft (5) center line, BB is the center line of the power disc (1) center to the universal joint bearing (7).

The power disk (1) is fixed to the power shaft (2). The power disk (1) is not equipped with a transmission bearing (4) at the center, the transmission bearing (4) is connected to the transmission shaft (5), and the transmission shaft (5) is another. One side is connected to the transmission universal joint (6), the universal joint (6) is mounted on the transmission universal joint (6), and the universal joint bearing (7) is mounted in the fixed bearing seat (8), and the transmission universal joint (6) Connect the output shaft (9). It is also possible to mount the power disk universal joint (10) between the transmission bearing (4) and the transmission shaft (5) on the power disk (1).

In order to perform the shifting and limited slip differential, the two power discs (1) on the device described above are connected together by a ring gear (3), and the respective drive shafts (5) and transmissions on the two power discs (1) The joint of the universal joint (6) and the output shaft (9) passes through the universal joint bearing (7) through the center of the mutually opposite power disk (1) and then through the two fixed bearing seats (8). The gear on the power shaft (2) meshes with the ring gear (3).

When the engine does not input power and the power plate (1) does not move, the vehicle maintains the driving state under the action of inertia, the wheel rotates with the output shaft (9), and the transmission shaft (5) is wound around itself by the transmission universal joint (6). The center line AA rotates.

When the engine inputs power and the power disk (1) rotates against the resistance of the vehicle, the rotating shaft (5) is rotated around the center of the power disk (1) to the center line B-B of the universal joint bearing (7).

The superposition of the rotation and revolution of the transmission shaft (5) increases the rotation speed of the output shaft (9), and the rotation speed of the output shaft (9) increases, and the rotation of the transmission shaft (5) and the speed of the vehicle also increase, and the transmission shaft (5) revolves. And the rotation and superposition, the output shaft (9) speed increases again, that is, the power disk (1) rotates at a certain speed, the output shaft (9) will have higher and higher speed, and the speed of the vehicle will be faster and faster (required) Satisfying the provided power can overcome the resistance of the vehicle. After a certain period of time, the required vehicle speed will be reached. If the vehicle speed is to be reduced, the power disk (1) will not be powered or braked to achieve the purpose of shifting.

In Fig. 5, when the power shaft (2) and the ring gear (3) rotate, the two mutually opposite power disks (1) are rotated, and the combined two transmission shafts (5) are not connected together, and their rotation is The rotational speeds are not necessarily equal, and the rotational speed of the side with a large resistance at the time of turning is lowered to form a differential. The rotating shaft (5) revolves, and the whole device is a whole. When one side is slipped or suspended, the rotating speed of the rotating shaft (5) of the two sides does not change, and the revolution speed of the rotating shaft is equal to the rotating speed of the power disc (1), so the resistance is large. The rotating shaft (5) and the output shaft (9) here increase the torque and play a limited slip.
