  • Patent number: 8544862
    Abstract: In a vehicle steering device, extendable portions whose elastic properties corresponding to a force acting in a compressing direction and whose elastic properties corresponding to a force acting in a stretching direction are asymmetrical are disposed in a symmetric fashion at intermediate sections of tie rods. Thus, an effective steering gear ratio with respect to leftward and rightward steering can be properly changed in accordance with a vehicle speed by using a simple configuration that does not use a complex mechanism having a motor. In this case, a steering gear ratio can be mainly changed for one of the wheels, while a linear lateral force corresponding to steering can be generated at the other wheel. Moreover, since the steering gear ratio can be changed mechanically without performing motor control, the occurrence of control delay can be prevented, thereby reliably preventing deterioration of the driver's operational feel.

  • Patent number: 7793957
    Abstract: A steering shaft (2) penetrates a head tube (1) fixed to a vehicle body (A) of a motorcycle. The steering shaft (2) is coupled to a front wheel and handlebars of the motorcycle. A linear damper of a double-rod type is enclosed in the steering shaft (2). When the steering shaft (2) rotates with respect to the vehicle body (A), a feed screw (12) engaged with a screw portion (11) on the outer circumference of one of the piston rods (6a, 6b) causes the linear damper to operate. By enclosing the linear damper in the steering shaft (2), a space for disposing the steering damping device can be minimized. The feed screw (12) converts a rotational displacement of the steering shaft (2) into an axial displacement of the piston rods (6a, 6b) such that a bending load does not act on the piston rods (6a, 6b).

The damping device interacts with the steering grip either directly or indirectly to damp relative motions between the steering grip and the manual force regulator.

  • Patent number: 6681883
    Abstract: A system for reducing steering nibble and other vibrations in a power-assisted steering system increases the amount of damping force when a power steering boost system is applying little or no steering force to the steering actuator, and reduces the amount of damping force when the power boost system is applying significant steering force to the steering actuator. A damping member is formed of a polymer material and is urged into contact with the steering actuator by a spring-biased clamping member. A shuttle valve regulates pressure from the hydraulic steering boost system to overcome the spring biasing force whenever hydraulic pressure is applied to the steering actuator. The preload of the spring biasing mechanism is varied by an electronic control unit that receives inputs from a driver-activated switch, and from vehicle condition sensors to allow automatic, adaptive adjustment of the damping to optimize driving comfort and safety.

  • Publication number: 20030160413
    Abstract: Engagement parts 52c of the locking device for a steering shaft are formed on a side face of a driven gear of a reduction gear mechanism which is fastened to a steering shaft 2. Since a locking part 6a is arranged near the reduction gear mechanism, elements related to a locking function can be removed from the key cylinder of the engine key, so that the key cylinder of the engine key can be downsized, or can be arranged in another position. Consequently, even in a state where a reduction gear mechanism, a steering assist motor and the like are arranged in the middle of the steering shaft, a longer stroke of the impact absorbing mechanism in comparison with conventional mechanisms can be ensured, utilizing a decrease in length of the downsized or reduced key cylinder in the axial direction of the steering shaft 2.

  • Patent number: 6561305
    Abstract: A damper for a vehicle rack and pinion-type power steering system reduces or eliminates high frequency and low amplitude vibrations commonly associated with high-speed steering wheel shake. The damper includes a hydraulically actuated clutch that is energized by a spring in the damper. The damper locks or inhibits rotation of a steering shaft coupled to the rack and pinion assembly while the vehicle is traveling straight down the road to absorb the input energy and cancel any vibration from the wheels, suspension or road. The clutch is released when there is any steering wheel input from the operator. Increased pressure from the power steering pump as a result of steering wheel input increases the pressure in the damper to compress a spring and release the multi-disk clutch. This allows the steering system to behave in an acceptable manner by not adding any friction or extra force requirements to the driver and providing acceptable feel and return to center characteristics for the steering system.

    Abstract: A vehicle steering system includes a steering wheel and a steering shaft coupled between the steering wheel and wheels of the vehicle. The shaft is operable for rotating when the steering wheel is turned to thereby turn the vehicle wheels. A vibration damping system for absorbing vibrations in the steering wheel and shaft includes a rotor coupled to the steering shaft to rotate with the shaft and a case surrounding the rotor and a clutch surface proximate the rotor. A magnetic circuit generates a magnetic flux in the rotor. The rotor is operable to engage the clutch surface and thereby vibrationally couple the steering shaft to the case to absorb vibrations in the shaft, and when a magnetic flux is generated therein, to disengage the clutch surface so that the steering shaft may more freely rotate.

  • Patent number: 6086074
    Abstract: A steering lock mechanism for a steerable axle assembly. The mechanism includes a fluid-actuated pin mounted within a cylinder. The cylinder is carried by a plate attached to a steerable wheel end. The pin carried by the cylinder has a tapered end which engages a tapered hole. When these tapered components are in engagement, steering motion of the steerable wheel end is prevented. The mechanism has several significant features, one of which is a fail-safe design in which a mechanical spring urges the pin to assume an extended or locking position in the event of failure of the pneumatic actuating system. The mechanism is designed so that the pin will find the hole as the steered wheels sweep past the straight ahead position, in the event of a failure of the fluid actuation system used to retract the pin.
