  • Patent number: 6467371
    Abstract: A vehicle control device, in particular a clutch mechanism for a tractor, includes a control lever and guide mechanism in which the lever is selectively movable from a first rest position to a second engaged position. The control lever is subjected to the action of an elastic apparatus operable to move the lever into the first rest position if the lever is released before reaching a given point along the guide mechanism. The elastic apparatus also being operable to move the control lever into the second engaged position if the control lever is released past the given point.

  • Patent number: 6464213
    Abstract: In the vibration isolating apparatus of the present invention, a controller provides drive current to an electromagnet when shaking vibration is being generated. This causes an intermediate plate to be attracted to the electromagnet thereby preventing elastic deformation of a first elastic piece caused by load transmitted from a top plate. Therefore, the static spring constant of an elastic body can be made larger than when the electromagnet is not being operated. Furthermore, the controller shuts off the supply of drive current to the electromagnet when idling vibration is being generated. This causes the intermediate plate to move away from the electromagnet thereby enabling elastic deformation of the first elastic piece cause by the load transmitted from the top plate. Therefore, the static spring constant of the elastic body can be made smaller than when the electromagnet is operated.

  • Patent number: 6464306
    Abstract: A brake pedal feel emulator for a motor vehicle brake system includes a housing having a bore for supporting a first piston operably connected to a brake pedal. An elastomer spring encapsulating a magnet or magnetized by the dispersion of ferrous particles throughout the spring body is engageable by the first piston and is disposed in the emulator housing. A second piston is disposed in the housing and engaged with the elastomer spring and with a mechanical spring. Hall effect sensors mounted on the emulator housing sense changes in a magnetic field generated by the magnet to provide signals to a controller proportional to travel and force exerted on the brake pedal for use in controlling the vehicle brake system.

  • Patent number: 6464051
    Abstract: A damper body for a magnetorheological (MR) damper and associated methods of forming the damper body. The damper body is formed of a base material, such as a steel, and is coated with an abrasion-resistant layer comprising chromium. The layer of chromium provides a sliding wear surface for sliding contact with a reciprocating piston. To avoid high-stress abrasive wear over the expected service life of the magnetorheological damper, the layer of chromium has a minimum thickness greater than or equal to a minimum thickness of about 8 &mgr;m. In other embodiments, before applying the abrasion-resistant layer of chromium, the damper body is coated with a layer of a hard coating material having a hardness greater than the hardness of the base material. The effective hardness of the damper body is a composite of the respective hardnesses of the base material comprising the damper body and the layer of hard coating material.

  • Patent number: 6460663
    Abstract: A hydraulic vibration damper for motor vehicles comprising a cylinder (1) containing damping fluid and a sealed, axially displaceable piston rod (2) that plunges into said cylinder. A damping piston (3) is secured to the lower end of the piston rod and divides the cylinder area into two working areas (4, 5). Said damping piston is provided with passages that can be modified and which are controlled by throttle valve bodies, in addition to a bypass for the pressure and traction stage, whereby the cross-section of the bypass is adjusted by an electrovalve that functions in three or more stages and the toroid coil more or less opens a valve slide (13), whereupon two or more bypass openings are released in a successive manner. The inventive damper is designed in such a way disruptive influences caused by constantly changing hydraulic forces arising from the flow of the damping agent are reduced when the flow from the bypass channels is shifted or controlled.

  • Patent number: 6460662
    Abstract: A vibration damping device is mounted between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. A cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with an outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. A fluid transfer duct is formed between the housing and piston and provides communication between fluid subchambers formed on opposite sides of the piston within the piston chamber. An electrode is attached to either the housing or piston for applying a voltage across the duct to affect the rheological response of an electrorheological (ER) fluid flowing therethrough to provide a controllable mechanism to modify the damping force characteristics of the device. Each end of the piston rod is slidably supported by a slide bushing assembly which is mounted within an end of the housing.

  • Patent number: 6460941
    Abstract: In a method of controlling the braking pressure variation during EBD control, during a braking operation, the vehicle deceleration is sensed and evaluated as a control criterion, and an increase in the braking pressure in the rear-wheel brakes is only permitted if the vehicle deceleration after commencement has risen above a predetermined minimum value, or if there are criteria which indicate brake fading or a brake malfunction, or if the vehicle deceleration exceeds a defined limit value.

  • Patent number: 6460943
    Abstract: A method controls brake pressure for a motor vehicle pressure medium-actuated power brake system in which the adjustment of a proportionality factor (k) between deceleration and brake pressure starting from an initial value (ko) is limited to a range bounded by a lower limit value and an upper limit value in which range the initial value (ko) is contained. This produces a warning travel of the pedal when excessive deviation of the brake pressure from the expected value occurs. The warning travel informs the driver of the braking effect which is deviating excessively from the expected degree. Methods are known in which a specific travel (sp) of the brake pedal is interpreted as a setting of a specific desired deceleration (zs) of the vehicle and the required brake pressure is set automatically if appropriate by incrementally adjusting a variable proportionality factor (k).

  • Patent number: 6460428
    Abstract: In connection with an intermediate anchoring of a manipulation cable connecting between a manipulation side and an actuation side of an automobile transmission mechanism, an intermediate anchoring bracket 22 of the manipulation cable 4 is provide integral with the starter 2. Specifically, a front bracket 21 of the starter 2, which is attached to a transmission block 1 with a high positional accuracy according to an original purpose of improving engagement between a ring gear 32 and a pinion 23, and the anchoring bracket 22 defining the intermediate anchoring point position of the manipulation cable 4 are formed integral. By merely attaching the starter 2 to the transmission mechanism block 1 with a small number of parts, an accurate positioning of the anchoring bracket 22 with respect to an actuation point 1a is realized, thereby, a positional accuracy between the intermediate anchoring point position and the actuation point 1a can be improved.

  • Patent number: 6460666
    Abstract: The damper includes a damper housing and a piston assembly reciprocating therein. The damper housing includes an attachment device formed of an interior partially circular wall with a triangular cross section thereby forming an interior partially circular apex for engaging a cylindrical boss. This allows the damper to rotate about an axis of the interior partially circular wall and pivot about an axis perpendicular to the rotational axis. Additionally, the piston assembly includes a detent protrusion formed from a stem supporting a head, the radius of the head being greater than that of the stem. The detent protrusion is engaged by a keyhole-shaped aperture with a first portion with a radius of curvature substantially equal to that of the stem and a second portion with a radius of curvature substantially equal to that of the head. The detent protrusion can therefore rotate within the keyhole-shaped aperture.
