A transmission arrangement (16) for an at least partially electrically driven vehicle (1) includes a first electric machine (3a) defining a first central longitudinal axis (9a) and having a first gear stage (6a) and a second gear stage (7a). The arrangement further includes a second electric machine (3b) defining a second longitudinal axis (9b) and having a first gear stage (6b) and a second gear stage (7b). Further, the arrangement includes a transmission housing (2), with the first and second electric machines (3a, 3b) being arranged in the transmission housing (2). Additionally, the arrangement includes a differential (8) drivingly connected to the second gear stages (7a, 7b) of the first and second electric machines (3a, 3b). The first and second central longitudinal axes (9a, 9b) are axially parallel to each other on a circular path (10) perpendicular to an output axis (5).

A multi-speed transmission (01) having a px and having a zx is described. The px is equipped with a sun wheel (84) and at least one planet wheel (08). The cycloidal gear stage equipped with a ring gear (02) with a ring gear axis (20), at least one cycloidal disk (05, 06) rolling in the ring gear, with at least one off-center opening and with a number, equivalent to the number of planet wheels (08), of shared off-center eccentric shafts (03), each connected nonrotatably with a planet wheel (08) and located jointly rotatably around the ring gear axis (20) and having a number of eccentric portions (31, 32), equivalent to the number of vbs (05, 06), which are each supported rotatably in a respective off-center opening of the at least one cycloidal disk (05, 06). The transmission (01) is distinguished by a support of its gear stages relative to the ring gear (02), also called and/or capable of being called a load-bearing body and being for instance at least a part of its machine frame, with bearing elements located exclusively on one side of the ring gear (02). First molding surfaces (33) are embodied on the eccentric shafts (03), and second molding surfaces (82) are embodied on the planet wheels (08), with which molding surfaces the planet wheels (08) mesh with the first molding surfaces (33) on the eccentric shafts (03).

A freewheel for changing a transmission characteristic of a planetary transmission for a motor vehicle transmission. The freewheel has a first ring which has a first blocking contour, a second ring which is rotatable relative to the first ring and which has a second blocking contour, tiltable blocking bodies which can be caused to engage into the first blocking contour and into the second blocking contour, and a switching element for tilting the blocking bodies. The switching element, in a blocking position, clamps the blocking bodies immovably to the first blocking contour and to the second blocking contour, in a freewheel position, allows unidirectional freewheeling, and in an inactive position, holds the blocking bodies down on the first ring so as to be spaced apart from the second ring.
