The first protruding gear is configured so that, when the modular gear transmission is in the assembled configuration, the first protruding gear protrudes from the first transmission body and is rotatably engaged with the first intermediate gear set, the first protruding gear configured to rotate around a first referential axis of rotation.

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.

A control device for mechanically actuating a component may include an electric motor, which may comprise a stator and a rotor with a driveshaft, an output shaft for directly or indirectly actuating the component, a transmission, which may drive-connect the driveshaft to the output shaft and which may comprise a worm drive with a worm and a worm wheel, and a drive axis around which the driveshaft may be rotatable and which may extend inclined to an output axis about which the output shaft may be rotatable. The worm, with respect to the driveshaft, may be arranged non-rotatably and may mesh with the worm wheel, which may be rotatably arranged on the output shaft and non-rotatably connected to a first gear wheel, which may be rotatably arranged on the output shaft and may mesh with a second gear wheel, which may be rotatable about an intermediate axis extending parallel to the output axis and may be non-rotatably connected to a third gear wheel, which may be rotatable about the intermediate axis and may mesh with a fourth gear wheel, which may be non-rotatably arranged on the output shaft.
