Embodiment Construction

[0041] figure 1 Shows an active swing stabilization device for a multi-train wheeled motor vehicle, which has a torsion bar 3 divided into two torsion bar parts 1, 2 and an effective implementation arranged between the two torsion bar parts 1, 2 器4. This active swing stabilizer is arranged perpendicular to the longitudinal axis of the vehicle; its free end is connected to a wheel support not shown in the figure. The actuator 4 has a hollow cylindrical housing 5 in which an electric drive device not shown in the figure and a planetary gear device connected to the drive device which is also not shown in the figure are installed. The housing 5 is connected to the torsion bar part 2 in a rotationally fixed manner. The driven shaft of the planetary gear, not shown in the figure, is connected to the torsion bar part 1 in a rotationally fixed manner. In the case of operating the actuator, the two torsion members 1, 2 rotate with each other and generate torque.

Abstract

Disclosed is a gear (8) for a gear train, said gear (8) being split into two axially adjacent spur gears (11) and being provided with a torsion spring (14) that has the shape of the segment of a circle; a slot (18), into which two cams (17) that are each associated with one of the two spur gears (11) engage, is formed between the circumferentially opposite ends (20) of the torsion spring (14), oneof the cams (17) being associated with one of the two ends (20) of the spring, and the other cam (17) being associated with the other end (20) thereof; the two cams (17) are arranged in such a way asat least substantially not to overlap in the axial direction.

Description

Technical field [0001] The invention relates to a gear used in a gear transmission device, especially a planetary gear transmission device. Background technique [0002] From WO 03 / 056141 A1, a gear according to the features of the preamble of claim 1 is known. The gear that is divided into two spur gears adjacent in the axial direction has a fan-shaped torsion spring. A gap is formed between the spring ends facing each other in the circumferential direction, and the two are assigned to the two positive The bosses of the gears are embedded in the gap, one boss is assigned to one of the spring ends, and the other boss is assigned to the other spring end. When the gears are assembled into the transmission, the two spur gears mesh with the embedded gears without backlash. In the constructed rotational position of the two spur gears, the bosses arranged one after the other on the outer peripheral side are shifted relative to each other in the outer peripheral direction in such a wa...
