Patent number: 8162328Abstract: By bending and stretching a link mechanism, both left and right wheels of a vehicle can be inclined toward inside of cornering to generate a camber thrust as a lateral force, i.e. an increase in cornering force. Further, by bending and stretching the link mechanism, the passenger compartment can be inclined in accordance with inclination of a connecting link, and thus the center of gravity of the vehicle can be moved toward its inner wheel during cornering. By preventing lifting of the inner wheel during cornering, cornering performance is improved. Because the passenger compartment is inclined toward the inner wheel during cornering, centrifugal force is less likely to be felt by the occupant.Type: GrantFiled: October 31, 2006Date of Patent: April 24, 2012Assignee: Kabushikikaisha Equos ResearchInventors: Munehisa Horiguchi, Masahiro Hasebe, Nobuaki Miki, Takumi Tachibana, Takashi Naito, Katsunori Doi, Tsukasa Hosokawa

Patent number: 7500677Abstract: A sway control arrangement configured to control movement of a product storage tank supported on a wheeled chassis assembly is provided. The wheeled chassis assembly includes a leaf spring in support of a frame and a tank on a transverse axle relative to a forward direction of travel. The sway control arrangement includes a master cylinder actuator in fluid communication with a pair of slave cylinders. The master cylinder is mounted between the frame and the leaf spring. The pair of slave cylinders are spaced apart from one another and mounted between the tank and the frame. The master cylinder communicates a fluid signal representative of a movement of the leaf spring relative the frame. In response to the fluid signal, the pair of slave cylinder actuators reduces movement of the tank from generally level alignment relative to the axle.Type: GrantFiled: June 15, 2006Date of Patent: March 10, 2009Assignee: CNH America, LLCInventor: Bruce G. Bastin

Patent number: 7494132Abstract: A roll control actuator for a stabilizer bar includes an outer housing that is fixed to a first bar portion and a shaft that is fixed to a second bar portion. The shaft is helically connected to a piston that is received within an interior chamber formed inside the outer housing. The piston separates the interior chamber into first and second fluid chambers. An anti-rotation mechanism is fixed to the outer housing and cooperates with the piston to restrict the piston to axial movement relative to the outer housing. The first and second fluid chambers are selectively pressurized to control roll stiffness by moving the piston within the outer housing.Type: GrantFiled: June 28, 2005Date of Patent: February 24, 2009Assignee: ArvinMeritor Technology, LLCInventor: Eric A.

Patent number: 7494141Abstract: In this vehicular chassis system, the vehicle's passenger compartment and wheels incline toward the turning center side in such a manner, that the wheels can be tilted independently from steering. This vehicle has a steering apparatus controlling the steering, and a separate apparatus controlling the lateral leaning. The lean is controlled mechanically using a pendulum, and forced lateral leaned using a control unit, or manually with the transfer of body weight using several pinions with a set ratio to control the passenger compartment lateral lean in conjunction with the wheel lateral lean. An electric DC servo gear motor can be used to control the lateral lean, that in turn moves a pinion, which moves a rack and lateral movable cross member, while controlling the lateral leaning wheels and pulling the tilt support bar pivotally attached to a passenger compartment in the same leaning direction.Type: GrantFiled: March 2, 2005Date of Patent: February 24, 2009Inventor: Todd Richard Bouton

Publication number: 20080309032Abstract: An example roll control device uses differential pressure values, for example, that are conveyed by a motor driven pump to a first actuator associated with a first stabilizer. The differential pressure values are also conveyed from the motor driven pump to a second stabilizer through a proportional valve in one example. In another example, multiple actuators are utilized with each actuator being associated with a separate motor driven pump in communication with a common controller.Type: ApplicationFiled: August 20, 2008Publication date: December 18, 2008Inventors: James Keane, Simon Dean, Edward H.

Publication number: 20080197597Abstract: The invention relates to a motor vehicle (1) of the type with four wheels (10), which consists of: a driver's cab which is only large enough to accommodate one person widthways and which is solidly connected to a chassis comprising a driver protection structure (4); and means for balancing the vehicle when negotiating bends and/or on surfaces that are inclined in relation to the horizontal, by inclining the chassis and the two front wheels simultaneously. The vehicle also comprises inclination-locking means which are actuated automatically when the vehicle is stopped or travelling at a reduced speed. The inventive vehicle further comprises means for limiting the angle of inclination to a maximum value such that, when stopped, the vehicle does not tilt.Type: ApplicationFiled: July 7, 2005Publication date: August 21, 2008Inventors: David Moulene, Thierry Moulene

Patent number: 7314221Abstract: A driver controlled wedge and track bar adjustor for a race car. A controller located inside the driver's compartment of the race car is coupled to a drive which is operatively coupled to adjusting rods. The controller may be configured to initiate a predetermined amount of rod adjustment. Wherein the operative coupling may consist of a system of pulleys and belts and the like which transfer the motion of the drive to the adjusting rods. The adjusting rods are already present in many race cars and are used to adjust the wedge or track bar of the vehicle during pit stops. A visual display may also be attached which shows the state of the wedge or track bar.Type: GrantFiled: April 5, 2005Date of Patent: January 1, 2008Inventor: Clifford Everlith
