By arranging the soft shaft support mechanism 3, the soft shaft can be firmly arranged on the soft shaft support mechanism 3, ensuring that the soft shaft 2 can be normally used during gear shifting.

[0022] The soft shaft support mechanism 3 includes a bottom plate 301 connected with the transmission 1, which is the basis of the entire support structure. The bottom plate 301 is provided with threaded holes for connecting the transmission 1 by bolts, which can provide stability and support to ensure the fixation of the entire soft shaft support mechanism 3. The bottom plate 301 is welded with a first connecting plate 302 and a second connecting plate 303. At the same time, the first connecting plate 302 and the second connecting plate 303 have simple structure, which can ensure the structural rigidity, strength and durability required by the function with simpler structure, less material and simpler process.

[0023] The first connecting plate 302 includes a first flat plate 314, one end of which extends out a first bent plate 315. The first bent plate 315 extends from one end of the bottom plate 301 to the other end and adopts a bridge arch structure, which can make the first connecting plate 302 have higher strength and rigidity while ensuring the welding strength of the first connecting plate 302 and the bottom plate 301. At the same time, the first connecting plate 302 adopts a bent structure to strengthen its own strength and rigidity.

[0024] The second connecting plate 303 includes a second flat plate 316, one end of which extends out a second bent plate 317. The second connecting plate 303 has a bent structure to increase its own strength and rigidity. At the same time, the area of the welding position is reduced, which can realize more reasonable stress condition, reduce the processing cost, reduce the influence of welding processing on the material, and further reduce the influence on the overall structure.

[0025] The first connecting plate 302 is provided with a first mounting hole 318, and one end of the first clasp 310 passes through the first mounting hole 318 and is connected to the first connecting plate 302 by bolts. The second connecting plate 303 is provided with a second mounting hole 319, and one end of the second clasp 312 passes through the second mounting hole 319 and is connected to the second connecting plate 303 by bolts. The other end of the first clasp 310 and the second clasp 312 is respectively provided with a mounting hole for the soft shaft 2. The first clasp 310 and the second clasp 312 are sleeved on the soft shaft 2 through the mounting holes.

[0026] The first weight-reducing hole 304 is arranged on one side of the first bending plate 315 on the bottom plate 301, which can reduce the manufacturing cost and reduce the weight of the bottom plate 301 itself. It will not affect the structural strength of the transmission 1 housing itself, and will not cause serious resource waste.

[0027] The first connecting plate 302 is provided with a second weight-reducing hole 305, and the second connecting plate 303 is provided with a third weight-reducing hole 306. The second weight-reducing hole 305 and the third weight-reducing hole 306 can reduce the manufacturing cost of the first connecting plate 302 and the second connecting plate 303, and also reduce the weight of the first connecting plate 302 and the second connecting plate 303 itself. It will not affect the structural strength of the transmission 1 housing itself, and will not cause serious resource waste.

[0028] The bottom plate 301 is provided with a third connecting plate 307 for fixing the brake air pipe. The third connecting plate 307 is of square structure, which further improves the strength and durability of the third connecting plate 307, and ensures that it can withstand repeated mechanical stress during long-term use. The third connecting plate 307 is provided with a fourth weight-reducing hole 308, which can reduce the weight of the third connecting plate 307 itself. It will not affect the structural strength of the transmission 1 housing itself, and will not cause serious resource waste.

[0029] The third connecting plate 307 is provided with a reinforcing rib 309 at the connection with the bottom plate 301. The reinforcing rib 309 can make the connection of the third connecting plate 307 and the bottom plate 301 more stable.

[0030] The side of the first connecting plate 302 connected with the bottom plate 301 is of arch structure, which improves the strength and durability of the first connecting plate 302, and ensures that it can withstand repeated mechanical stress during long-term use.

[0031] One end of the bottom plate 301 is a square plate, and the other end of the bottom plate 301 is a trapezoidal plate connected with the square plate. The bottom plate 301 is designed to ensure good matching with the transmission 1, and can better adapt to the transmission 1 in space.
