Quadrilateral Suspension Patents (Class 267/222)
  • Patent number: 10787217
    Abstract: This invention relates to a tilting mechanism for wheeled vehicles such as bicycles both electrical and manually powered, motorcycles, mopeds, scooters and the like. The wheeled vehicle, preferably with three wheels or more, driving like a 2-in-line vehicle and handles the same way in the turns and when driving straight. The tilting mechanism for a multiple wheeled vehicle, comprising a tilting mechanism that allows for leaning body and wheels into a turn and independent adjustment of the turning radius, while inducing an effect to the two front wheels similar to Ackerman steering compensation. The principle of the tilting mechanism is a parallelogram structure, which comprises a top rod, a bottom rod and a pair of connecting rods, pivotally connected to each other. To each of the connecting rods a pair of steering elements is pivotally connected and on two steering elements a pair of wheels is connected.

  • Patent number: 10718395
    Abstract: A bearing bushing, for example, for a motor vehicle. The bearing bushing is switchable between a first and a second stiffness stage. The bearing bushing has a first elastomer ring, which is arranged rotationally fixedly on an outer circumferential surface of an inner ring, and a second elastomer ring, which is arranged rotationally fixedly on an inner circumferential surface of an outer ring. Radially between the two elastomer rings, an intermediate ring makes contact in a rotationally fixed manner with the two elastomer rings. To change in stiffness of the bearing bushing, the first elastomer ring can be bridged by the intermediate ring and at least one blocking ring which is arranged on the bearing bushing at an end side.

  • Patent number: 10144260
    Abstract: The invention provides an axle for wheels of a two-track motor vehicle. The axle has, on each vehicle side, a wheel carrier, a damper strut, a transverse link and a transverse leaf spring which controls the wheel at least partially laterally and/or in the vehicle longitudinal direction. The damper strut has a damper tube and a damper piston which can be moved in the damper tube along a damper longitudinal axis. The damper strut is attached by the damper tube to the wheel carrier. The transverse link is attached by a wheel-carrier-side end region to the wheel carrier. The transverse leaf spring extends substantially in the vehicle transverse direction and has at least one wheel-carrier-side end region. The transverse leaf spring is attached by the wheel-carrier-side end region thereof to the damper strut and is supported on the damper strut.

  • Patent number: 9387534
    Abstract: A method for forming a control arm is provided. The method includes providing an insert and a mold and also includes overcasting the insert within a metal in the mold. The insert defines a recess that is shaped for receiving a mating component. After the insert is overcast within the metal, the mating component may be positioned or mounted within the recess of the insert. A related control arm is also provided.

  • Patent number: 8616352
    Abstract: Provided is a height adjustable suspension unit that can smoothly lift and lower a vehicle body without the need to supply fluid to a shock absorber. The height adjustable suspension unit includes: a shock absorber S having a cylinder 1 and an extensible rod 2 disposed in the cylinder 1 to be able to advance and retract, the extensible rod 2 having an end portion that is coupled to a chassis X; a coil spring 4 mounted around the extensible rod 2, the coil spring 4 having a lower end supported on a spring base 3 that is attached to the upper end of the cylinder 1; and a lifting and lowering mechanism D including a gear mechanism A that is rotationally driven by a power source, a power conversion section B that converts power transmitted from the gear mechanism A into power to move the cylinder 1 up and down, and a guide section C that guides the up and down movement of the cylinder 1.

  • Patent number: 6894144
    Abstract: The invention relates to elastomer materials based on N-alkylaziridino compounds with a base component which contains the aziridino compounds and with a catalyst component which contains at least one acid-acting compound, both components being mixed before use, characterized in that, as acid-acting compound of the catalyst component, one or more boric acid complexes are used which can be obtained by reaction of boric acid and/or a boric acid derivative with at least one OH-functional compound, the OH functions being able to be present wholly or partly protected, and this reaction being carried out either as an upstream reaction between boric acid and/or a boric acid derivative and at least one such OH-functional compound or during or after the preparation of the catalyst component or by mixing the catalyst component with the base component which then contains at least one OH-functional compound.

  • Patent number: 6702265
    Abstract: A balance suspension system for a vehicle having a body and at least four wheels (FR, FL, BR, BL) independently supported for movement between upper and lower positions relative to the body, the suspension system includes a balance mechanism adapted to support suspension forces in the vehicle and a plurality of actuating elements (73, 74, 78, 79) which are responsive respectively to the positions of the wheels relative to the body and are operable on spaced apart points on the balance mechanism. The system also includes control means for controlling relative movement between the balance mechanism and the body. The control means act to redistribute suspension forces between the body and the wheels, thereby to induce predetermined suspension behaviour.
