Embodiment Construction

[0040] figure 1 Shown is an active roll stabilization device for a multi-train wheeled vehicle with a torsion bar 3 divided into two torsion bar parts 1 , 2 and an active actuating mechanism arranged between the two torsion bar parts 1 , 2 . device 4. This active roll stabilization device is arranged perpendicular to the longitudinal axis of the vehicle; its free end is connected to a wheel carrier, not shown in the drawing. The actuator 4 has a hollow cylindrical housing 5 in which an electric drive (not shown in the figure) and a planetary gear connected to the drive (also not shown in the figure) are accommodated. The housing 5 is connected to the torsion bar part 2 in a rotationally fixed manner. The output shaft (not shown) of the planetary gear is connected in a rotationally fixed manner to the torsion bar part 1 . When the actuator is actuated, the two torsion elements 1 , 2 rotate relative to each other and generate a torque.

Abstract

A gear (8) for a gear transmission, which is divided into two axially adjacent spur gears (11) and has a sector-shaped torsion spring (14), on the circumference of which the torsion spring A gap (18) is provided between the spring ends (20) facing each other in the direction, into which gap two bosses (17) respectively assigned to the two spur gears (11) engage, wherein , one of the bosses (17) matches one of the two spring ends (20), and the other boss (17) matches the other spring end (20), wherein the two The bosses (17) are arranged at least substantially without overlapping in the axial direction.

Description

technical field [0001] The invention relates to a gear for a gear transmission, in particular a planetary gear. Background technique [0002] A gear is known from WO 03 / 056141 A1. A gear that is divided into two axially adjacent spur gears has a sector-shaped torsion spring, which forms a gap between its circumferentially opposite spring ends, which are respectively assigned to two spur gears. The cams of the gear engage in this gap, one of the cams being assigned to one of the spring ends and the other cam being assigned to the other spring end. When the gear is assembled into the transmission, the two spur gears mesh with the embedded gear without backlash. In the designed rotational position of the two spur gears, the cams arranged one behind the other on the outer peripheral side are offset relative to one another in the peripheral direction in such a way that the cams press the spring ends of the torsion spring against one another with an enlarged gap. The prestress ...
