[0042] Such as Figure 4-Figure 6 As shown, in this embodiment, the left and right are described as Figure 4 or Figure 5 The left and right prevail.

[0043] The transmission shaft removal tool in this embodiment includes a cable 1, a first fixing sleeve 5 and a second fixing sleeve 6, and the cable 1 can pass through the two fixing sleeves and be fixed in the corresponding fixing sleeve. The two ends of the cable 1 are respectively fixed at two fixed sleeves, and the extension direction of the cable 1 is as follows: the cable 1 extends from the first fixed sleeve 5 to the right side of the first fixed sleeve 5, and the first fixed sleeve The right side of the first fixed sleeve 5 is bent to form a half locking ring 106 and passes through the first fixed sleeve 5 to reach the left side of the first fixed sleeve 5. After the left side of the first fixed sleeve 5 is bent to form a third traction ring 107, it passes through the second A fixed sleeve 5, then continue to exten...

Abstract

The invention provides a dismantling tool and method for a transmission shaft. The dismantling tool comprises a cable and a central ring, wherein the cable extends in such a way that from one end of the cable, the cable penetrates through the central ring and reaches the right side of the central ring, the cable is bent at the right side of the central ring to form a first locking ring and then penetrates through the central ring for a second time, the cable is bent at the left side of the central ring to form a first pulling ring and then penetrates through the central ring for a third time, the cable is bent at the right side of the central ring to form a second pulling ring and then penetrates through the central ring for a fourth time, and finally the cable reaches the other end; and the two ends of the cable are respectively provided with a first limit part and a second limit part which cannot penetrate through the central ring. The dismantling method comprises the following steps of: A. the first locking ring is sleeved on a step transition part of the transmission shaft located outside a transmission case, and the first pulling ring is pulled so that the first locking ring is reduced to tie up the transmission shaft; and B. the first pulling ring and the second pulling ring are simultaneously pulled in a direction departing from the transmission case, so that the transmission shaft goes out of the transmission case.

Description

technical field [0001] The invention relates to a dismantling tool and a dismantling method of a transmission shaft. Background technique [0002] During automobile assembly and maintenance, it is often necessary to disassemble the transmission shaft from the gearbox (or differential). At present, the common way of connecting the drive shaft and the gearbox is a spline circlip connection. After the drive shaft is installed in the gearbox, the C-shaped circlip assembled on the drive shaft springs off and is stuck in the gearbox. Inside, it achieves an axial fixation to prevent the drive shaft from coming out of the gearbox. [0003] However, this connection mode makes it difficult to disassemble the transmission shaft. Due to the large clamping force after the jump spring is released, it is difficult to pull the transmission shaft out by ordinary methods. The current common disassembly method is to use a crowbar to insert in the gap between the gearbox and the transmission...
