A gearbox for vehicles that includes a split gearbox, a main gearbox and a range gearbox, which is shiftable into a low range gear position and a high range gear position. The range gearbox includes a planetary gear with a ring gear wheel, a sun gear wheel and a planet carrier, on which at least one planet gear wheel is rotatably mounted. A gearbox housing surrounds the planetary gear. A first axially movable coupling sleeve engages the planet carrier with the gearbox housing. A second axially movable coupling sleeve engages the ring gear wheel with an output shaft to shift into a reverse gear. A crawler gear in the main gearbox is arranged to transfer torque through the gearbox when the range gearbox is shifted into the reverse gear.

An autonomous mobile work system (20) includes a drive wheel (34) that is connected to a frame (24) and a rotating blade assembly (36). The rotating blade assembly (36) includes a blade assembly axis of rotation (38) and is connected to the frame (24) within a housing (26). The mobile work system (20) further includes a single motor (40) operably connected to the blade assembly (36). The motor (50) includes a motor output shaft (44) and the motor output shaft (44) includes an output shaft axis of rotation (46). The mobile work system (20) still further includes a gear box (50) operably connected to the drive wheel (34) and the motor output shaft (44). The single motor (50) urges rotation of both the rotating blade assembly (36) and the drive wheel (34). The gear box (50) can include a planetary gear set (104) including a ring gear (110) defining cavities (120) at its outside diameter (124). A locking shaft (126) can rotate between an engaged position and a disengaged position with one of the cavities (120).

A motor vehicle transmission for coupling an electric machine to a drivetrain of an electrically driveable motor vehicle. The motor vehicle transmission includes a planetary transmission for converting a torque that is introducible by the electric machine. An internal gear of the planetary transmission has an input toothed gear for forming a spur gear stage with a drive shaft of the electric machine. A brake immobilizes a sun gear of the planetary transmission with a static housing. A clutch rotationally conjointly connects the sun gear to the internal gear. The brake and the clutch at least partially overlap as viewed in a radial or axial direction. By virtue of the overlap, it is possible for axial and radial structural space, respectively, to be saved, such that a motor vehicle transmission with a small structural space requirement is made possible.

A shifting manipulation-assisting device and a hub-embedded transmission, wherein in controlling pawls that restrain rotation of sun gears to perform shifting in a planetary gear set, shifting control is properly performed even with a small manipulation force. The shifting manipulation-assisting device includes a pawl control ring having an inner peripheral surface to control laying-down of control pawls, and an outer peripheral surface formed with rotation restricting protrusions; an angle control member positioned on an inner periphery side of a driver; pressing members supported on the angle control member, and positioned between the unidirectionally inclined recesses and an inner peripheral surface of the driver; an elastic connecting body connected to resiliently support the pawl control ring; a fixed support member non-rotatably fixed to the shaft and rotatably supporting the driver; and a return spring connected to reversely rotate and accordingly return the angle control member.
