Construction is achieved whereby durability is maintained while size and weight are reduced. Installation plate sections are provided on the top and bottom end sections of a pair of support columns. Bolts are inserted through through-holes that penetrate through the installation plate sections in the axial direction; the bolts are then screwed into screw holes provided in the axial direction of anchor sections of an actuator body and a connecting plate, and the bolts are further tightened, whereby the support columns are securely joined and fastened to the actuator body and the connecting plate.

Systems, devices, and methods are provided for the transmission of power in motor vehicles. Power can be transmitted in a smoother and more efficient manner, with smaller and even less mechanical components, by splitting torque into two or more torque paths. A power transmission apparatus comprises a power input shaft, a planetary gear set coupled to the power input shaft, and a variator, such as a continuously variable transmission (CVT), coupled to the gear set. The various components of the planetary gear set and the variator are arranged such that torque is split between two or more torque paths and then recombined before power is output to a gear box and a differential of the motor vehicle.

A variable transmission includes an input shaft, a planetary gear set drivingly engaged with a variator comprising, a variator carrier assembly, a first ring assembly, and a second ring assembly; and the output shaft, arranged with various combinations of brakes and clutches to produce transmissions with continuously variable or infinitely variable torque output ratios.
