ROLL STABILIZER FOR A MULTITRACK MOTOR VEHICLE

摘要

The invention relates to a roll stabilizer for a multitrack motor vehicle, comprising a split torsion bar (3), between the mutually facing ends of which an actuator (4) is arranged for transmitting a torsional moment. The actuator (4) has a housing (5) which is connected to one torsion bar part (1, 2) and in which a motor and a planetary transmission connected to the motor are arranged. The transmission output of the planetary transmission is connected to the other torsion bar part (1, 2), and the planet gears (9) of the planetary transmission mesh with a counter gear (28). A multistage planetary transmission is provided, the last output-side planet gear stage (8) of the planetary transmission being provided with planet gears (9), at least one planet gear (9) of which is split into two axially adjacent end gears (11) that can be rotated relative to each other, wherein a torsion spring (14) is operatively arranged between the end gears such that the split planet gear (9) engages with the counter gear (26) in a play-free manner.
