Embodiment Construction
[0023] The present invention will be further described below in conjunction with drawings and embodiments.
[0024] Such as figure 1 As shown, the hydraulic cylinder 3 of the present invention, as a part of the entire hub shell, is installed directly in front of the hub main body 2 by screws, and the axis of the hydraulic cylinder barrel 4 is parallel to the direction of the flow. The left end of the piston push rod 7 is threadedly connected with the hydraulic cylinder piston 6, and the front support 8 of the push rod supporting the front end of the piston push rod 7 is fixedly installed in the cylinder barrel 4 of the hydraulic cylinder. U-shaped sealing ring to prevent oil leakage of the hydraulic cylinder.
[0025] Such as figure 1 , figure 2 As shown, each side of the triangular push plate on the piston push rod 7 in the hub main body 2 is respectively installed with a rack 9 parallel to the piston push rod 7 through screws, and the gears at one end of the three gear s...
