Preferably, when both the input clutch assembly 112 and the output clutch assembly 126 are activated, i.e., when the first brake portion 119 of the input brake disc 113 abuts against the first transfer gear shaft 111, the first extension portion 124 of the input hydraulic piston 122 abuts against the first transfer gear shaft 111, the second brake portion 133 of the output brake disc 131 abuts against the second transfer gear shaft 125, and the second extension portion 138 of the output hydraulic piston 136 abuts against the second transfer gear shaft 125, the input gear shaft 109 and the output gear shaft 110 achieve an equal ratio output.
Preferably, referring to fig. 10 and 11, in the present embodiment, the first transmission shaft 120 is provided with an anti-slip structure 139, and when the first braking portion 119 of the input brake disc 113 abuts against the first transmission gear shaft 111, the anti-slip structure 139 is accommodated to increase the friction between the first braking portion 119 and the first transmission shaft 120. The anti-slip structure 139 is a plurality of coaxially disposed accommodating grooves. Similarly, the second transmission shaft 134 is also provided with an anti-slip structure 139, and the anti-slip structure 139 functions to increase the friction between the second brake 133 and the second transmission shaft 134.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
