Abstract
First and second cross-bars extend laterally across the width of a vehicle and are pivotally connected intermediate their lengths in scissors fashion. One end of each cross-bar is pivotally connected to a wheel support assembly which is in turn pivotally connected to the vehicle body by a spring and damper assembly. The other end of the first cross-bar is pivotally connected to the vehicle body by a hydraulic cylinder and piston assembly. The other end of the second cross-bar is pivotally connected via a lever to the actuator of a variable flow hydraulic valve. Lateral forces exerted by the wheels and cross-bars relative to the vehicle body during a turn operate the hydraulic valve to send a proportionate amount of hydraulic fluid to the upper or lower portion of the hydraulic cylinder to thereby prevent rolling of the vehicle body.
Claims20
An anti-roll system for a vehicle, comprising:
- means for rotatably supporting a first wheel;
- means for rotatably supporting a second wheel;
- a first spring and damper assembly connecting the first wheel supporting means to a first side of a vehicle body;
- a second spring and damper assembly connecting the second wheel supporting means to a second side of the body;
- a first cross-bar having a first end and a second end, the first end being pivotally connected to the first wheel supporting means;
- a second cross-bar having a first end and a second end, the first end being pivotally connected to the second wheel supporting means;
- means for pivotally connecting the cross-bars intermediate their ends;
- and
- control means operative during turning of the vehicle to exert forces on the cross-bars relative to the vehicle body to thereby oppose rolling of the vehicle body.
An anti-roll system for a vehicle comprising:
- means for rotatably supporting a first wheel;
- means for rotatably supporting a second wheel;
- a first spring and damper assembly pivotally connecting the first wheel support means to one side of a vehicle body;
- a second spring and damper assembly pivotally connecting the second wheel support means to the other side of the body;
- a first cross-bar having a first end and a second end, the first end being pivotally connected to the first wheel supporting means;
- a second cross-bar having a first end and a second end, the first end being pivotally connected to the second wheel wheel supporting means;
- means for pivotally connecting the first and second cross-bars intermediate their ends;
- a hydraulic cylinder and piston assembly pivotally connected at a first end to the second end of the first cross-bar and pivotally connected at a second end to the vehicle body;
- a hydraulic pump;
- variable flow hydraulic valve means having a movable actuator;
- a reservoir;
- a quantity of hydraulic fluid in the reservoir;
- means for connecting the second end of the second cross bar to the actuator of the hydraulic valve means;
- conduit means for connecting the pump, the reservoir, and the hydraulic piston and cylinder assembly;
- and
- the valve means being operable for directing the hydraulic fluid to and from the hydraulic cylinder and piston assembly upon movement of the actuator by lateral movement of the first and second cross-bars relative to the vehicle body during turning of the vehicle to thereby oppose rolling of the vehicle body.
