Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the gear shifting mechanism comprises a shell 1, an input shaft 2, a coupler 3, an output shaft 4, a cylindrical roller bearing 5, a spacer 6, a deep groove ball bearing 7, an oil seal 8, a connecting seat 9, a sliding sleeve 10 and a gear shifting mechanism 11.
The power take-off mechanism of the twelve-gear transmission is basically as shown in the attached figure 1 and comprises a shell 1, wherein an input flange is arranged at the front end (namely the left end) of the shell 1, and an output flange is arranged at the rear end (namely the right end) of the shell 1. An input shaft 2, a coupler 3 and an output shaft 4 are sequentially arranged in the shell 1 from left to right, the input shaft 2, the coupler 3 and the output shaft 4 are coaxially arranged, and the coupler 3 is a spline coupler.
The input shaft 2 is connected to the front end of the housing 1 through a cylindrical roller bearing 5, and the cylindrical roller bearing 5 is provided on the input flange. The front end (namely the left end) of the input shaft 2 penetrates through the front end of the shell 1 and extends out of the shell 1, the front end of the shell 1 is located in a main box of the transmission and is connected with a steering wheel in the main box, the specific connection mode is that a power take-off gear is arranged on the steering wheel of the main box, an input gear meshed with the power take-off gear is arranged at the front end of the input shaft 2, and then the input shaft 2 and the steering wheel synchronously rotate.
