Abstract
A stabilizer bar includes a housing configured to be fixed to a first side-bar, a hydraulic power unit and a clutch piston disposed within the housing, and a clutch ring configured to be fixed to a second side-bar. The hydraulic power unit is configured to selectively move the clutch piston from a first connected position to a second disconnected position.
Claims19
A vehicle stabilizer bar comprising:
- a housing configured to be fixed to a first side-bar, the housing defining a first portion of a first coupling;
- a hydraulic power unit disposed within the housing;
- a clutch piston disposed within the housing, the clutch piston defining:
- a second portion of the first coupling configured to cooperate with the first portion of the first coupling, such that the first coupling:
- i) torsionally couples the clutch piston to the housing, and ii) provides for axial movement between the clutch piston and the housing;
- and
- a first portion of a second coupling;
- a clutch ring configured to be fixed to a second side-bar, the clutch ring defining a second portion of the second coupling, the second coupling configured to cooperate with the first portion of the first coupling to selectively torsionally couple the clutch piston to the clutch ring;
- and
- the hydraulic power unit is configured to selectively move the clutch piston from a first connected position, in which the clutch piston is torsionally coupled to the clutch ring, to a second disconnected position, in which the clutch piston is torsionally uncoupled from the clutch ring.

A vehicle stabilizer bar comprising:
- a housing configured to be fixed to a first side-bar;
- a hydraulic power unit disposed within the housing, the hydraulic power unit having an actuator, a hydraulic fluid pump, and at least one fluid gallery;
- a clutch piston disposed within and torsionally coupled to the housing via a first coupling, the clutch piston configured to be selectively hydraulically actuated by the hydraulic power unit;
- and
- a clutch ring at least partially disposed within the housing and configured to be fixed to a second side-bar;
- and
- in a first connected position, the clutch piston is torsionally coupled with the clutch ring via a first hydraulic fluid pressure and a second coupling;
- and
- in a second disconnected position, the clutch piston is torsionally uncoupled with the clutch ring via a second hydraulic fluid pressure less than the first hydraulic fluid pressure and the second coupling.
6 more elements
A vehicle stabilizer bar comprising:
- a rotational axis;
- a housing configured to be fixed to a first side-bar;
- a hydraulic power unit disposed within the housing, the hydraulic power unit having:
- at least one fluid gallery;
- a hydraulic fluid pump fluidly connected to the at least one fluid gallery;
- an actuator configured to power the hydraulic fluid pump;
- a gearbox arranged between the actuator and the hydraulic fluid pump;
- and
- a hydraulic fluid reservoir fluidly connected to the at least one fluid gallery;
- a clutch piston slidably disposed within the housing and the hydraulic power unit, the clutch piston fluidly connected to the at least one fluid gallery and configured to be selectively hydraulically actuated by the hydraulic power unit;
- a clutch ring at least partially disposed within the housing and arranged concentrically with the clutch piston;
- and
- in a first connected axial position, the clutch piston is torsionally coupled with the clutch ring;
- and
- in a second disconnected axial position, the clutch piston is torsionally uncoupled with the clutch ring.
