Claim 1:
2. The continuously variable transmission with both equal-difference output and equal-ratio output according to claim 1, wherein the planetary-gear-set convergence mechanism comprises a front planetary gear mechanism and a rear planetary gear mechanism, wherein a ring gear of the front planetary gear mechanism is connected to a ring gear of the rear planetary gear mechanism, and the input end of the hydraulic transmission mechanism is connected to a sun gear of the front planetary gear mechanism;
the clutch assembly comprises a hydraulic path input clutch C1, a first variable transmission ratio output clutch C6, a sixth variable transmission ratio output clutch C11 and a coupling mechanism L, wherein the hydraulic path input clutch C1 is used for selectively connecting the output end of the input mechanism to the input end of the hydraulic transmission mechanism via a hydraulic path input gear pair i1; the first variable transmission ratio output clutch C6 is used for selectively connecting the output end of the hydraulic transmission mechanism to the equal-difference output mechanism via a first variable transmission ratio output gear pair i4; the sixth variable transmission ratio output clutch C11 is used for selectively connecting the output end of the hydraulic transmission mechanism to the equal-ratio output mechanism via a sixth variable transmission ratio output gear pair i9; the coupling mechanism L is used for selectively connecting the equal-difference output mechanism to the equal-ratio output mechanism;
the hydraulic path input clutch C1 and the first variable transmission ratio output clutch C6 are engaged to provide continuous hydraulic transmission H1 between the input mechanism and the equal-difference output mechanism; the hydraulic path input clutch C1 and the sixth variable transmission ratio output clutch C11 are engaged to provide continuous hydraulic transmission H2 between the input mechanism and the equal-ratio output mechanism; the hydraulic path input clutch C1, the sixth variable transmission ratio output clutch C11, and the coupling mechanism L are engaged to provide continuous hydraulic transmission H3 between the input mechanism and the equal-difference output mechanism and between the input mechanism and the equal-ratio output mechanism.
