Abstract
A transmission arrangement for motor vehicles has a planetary gear set acting as an axle step-up and reversing gear. The planet gears of the planetary gear set have two sets of teeth at different diameters. Synchronizing rings are arranged to minimize the structural space required. A housing for a following differential is connectable either with the planet gear carrier or else with a ring gear meshing with the larger planet gears by way of a sliding sleeve. The transmission has a continuously variable section preceding the planetary gearing.
Claims30
A transmission arrangement for vehicles comprising a housing, a planetary gear set contained in the housing including an axle step-up and reversing gear and a driven component following the planetary gear set, wherein the planetary gear set includes a planet gear carrier carrying planet gears having sets of gear teeth with different diameters and wherein one set of planet gear teeth engages a stationary first ring gear, another set of planet gear teeth engages a second ring gear, and one of the two sets of planet gear teeth engages a sun gear, and wherein either the planet gear carrier or the second ring gear is connectable to the driven component.
A drive system for a vehicle comprising a drive motor, a continuously variable transmission following the motor and having components with two principal axes of rotation and comprising a housing, a planetary gear set contained in the housing including an axle step-up and reversing gear and a driven component following the planetary gear set, wherein the planetary gear set includes a planet gear carrier carrying planet gears having sets of gear teeth with different diameters and wherein one set of planet gear teeth engages a stationary first ring gear, another set of planet gear teeth engages a second ring gear, and one of the two sets of planet gear teeth engages a sun gear, and wherein either the planet gear carrier or the second ring gear is connectable to the driven component, and including a starting and disengaging clutch following the transmission, wherein one of the centers of rotation of the variable transmission is coaxial with the axis of the planetary gear set.
