[0027] The following describes in detail the specific implementation of the installation structure of the transmission shaft encoder of a carrier vehicle according to the present invention in conjunction with the accompanying drawings.

[0028] See attached Figures 1 to 3 The installation structure of the transmission shaft encoder of the carrier vehicle of this patent includes a transmission shaft 1 and an encoder 2. The wheels of the carrier vehicle transmit power through the transmission shaft 1. The encoder 2 is installed at the end of the transmission shaft 1 and is used to control the precise parking control of the wheels.

[0029] The encoder 2 is fixed to the bracket 4 through the mounting plate 3. The mounting plate 3 is made of elastic metal material, such as a carbon stainless steel sheet or a manganese-containing steel sheet. Two 180-degree arranged support legs 5 are set at the front end of the mounting plate 3 and fixed to the bracket 4 by bolts. The encoder 2 is fixed by the support of the mounting plate 3.

[0030] A through hole 6 is provided on the bracket 4, and the inner shaft 11 of the encoder 2 passes through the through hole 6 of the bracket 4 and is connected to the flexible coupling 7. The transmission shaft 1 is also coaxially connected to the flexible coupling 7 to realize the transmission of the rotation of the transmission shaft 1 to the encoder 2.

[0031] The flexible coupling 7 comprises an elastic eight-shaped plastic 8 and a shaft sleeve 9 fixed at both ends. The elastic eight-shaped plastic 8 can be made of polyurethane and is formed into an eight-shaped structure by two circular rings with intersecting axes. The eight-shaped plastic coupling is an existing technology.

[0032] The outer circumference of sleeve 9 is provided with radial holes, which secure inner shaft 11 and drive shaft 1 via set screws 10. The center of inner shaft 11 is a shoulder 12, one end of which is fixedly and rotatably connected to encoder 2 and the other end is fixed to sleeve 9 of flexible coupling 7. The end of drive shaft 1 is a stepped shaft section 13, which is fixed to sleeve 9 of flexible coupling 7.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
