  • Publication number: 20140175857
    Abstract: A mounting structure of a wheel speed sensor ring includes an intermediate ring made of aluminum which is fastened to a hub of a wheel body together with a brake disc in a state where the intermediate ring is brought into contact with the brake disc, and a pulser ring is supported on the intermediate ring in a floating state. A supported portion of the pulser ring is provided at a center position within the intermediate ring, and the intermediate ring includes a plurality of seat plate portions on an outer periphery thereof which are fastened between hub and the brake disc. The mounting structure has a compact size which permits various thermal effects caused by the generation of heat in a brake disc to be effectively suppressed.

  • Patent number: 8528927
    Abstract: A steering apparatus for a vehicle includes a stem pipe disposed in a head pipe by upper and lower bearings interposed therebetween, a seal member for covering the upper bearing, and bottom and top bridges mounted on lower and upper ends of the stem pipe, respectively. A single fastening bolt, having a step formed between a head and a threaded surface thereof, is fitted in a pipe insertion hole of the top bridge and the upper threaded portion of the stem pipe. The stem pipe is firmly tightened and supported by a stem pipe slot-tightening mechanism of the top bridge. The fastening bolt is tightened by only a tightening force required to keep the fastening bolt from loosening. Also, a number of components required for the inventive steering apparatus is reduced, since an additional component, previously used for preventing loosening of a fastening bolt, is made unnecessary.

  • Patent number: 8479862
    Abstract: A branch joint is provided at the rear portion of an exhaust pipe. Second exhaust pipes with a small diameter arranged one above the other are branched at a position forward of an intersecting position P with a pivot plate. The second exhaust pipes are made to intersect the inside of the pivot plate. The gap between the pivot plate and the engine can be narrowed while ensuring a smooth exhaust. The exhaust path lengths of the second exhaust pipes are made to be offset from each other so as not to be the integral multiple of the wavelength of the exhaust sound in the operating area. This allows exhaust gases to interfere with each other in the muffler. Thus, the exhaust sound can be reduced and the muffler can be downsized. This allows for the slimming of the vehicle body without lowering the output of the engine.

  • Patent number: 7967102
    Abstract: A steering shaft support structure for an all terrain vehicle in which both forces of push and pull applied to an EPS unit are reduced when a load is applied to handlebars. The structure includes a steering shaft rotatably supported by a body frame and handlebars attached to the steering shaft. The EPS unit is also supported by the body frame. Two sets of adjustable joints are interposed between the steering shaft and the EPS unit in such a manner that their axes are shiftable. With this, if a load is applied to the handlebars, the adjustable joint associated with the steering shaft follows the inclination of the steering shaft, so that the connection point (swing point) of the adjustable joint associated with the EPS unit does not shift. This reduces both forces of push and pull applied to the EPS unit.

  • Patent number: 7857338
    Abstract: A steering damper ensures a wide longitudinal illumination range of a road surface when a light unit is provided and facilitates layout of parts and simplifies structure without degrading appearance. A steering damper mounting structure is provided for a vehicle, which includes a head pipe, a front fork, a fork bridge, and a steering damper. The steering damper is mounted on the fork bridge and the head pipe. The steering damper dampens a movement transmitted from a side of the front wheel to a handlebar. In this steering damper mounting structure, the steering damper is mounted to the head pipe and the top bridge and disposed on the side of the top bridge between the top bridge and the bottom bridge. Additionally, a light unit is disposed on the side of the bottom bridge between the top bridge and the bottom bridge.

  • Patent number: 7802805
    Abstract: A steering damper mounting structure of a vehicle includes a head pipe, a front fork, a fork bridge, and a steering damper. The front fork, which suspends a front wheel, is steerably disposed on the head pipe. The fork bridge connects left and right members of the front fork. The steering damper is mounted on the fork bridge and the head pipe. The steering damper dampens a steering directional movement transmitted from a road surface to a handlebar via the front wheel and the front fork. A lower mounting portion on a side of the head pipe is disposed on a side of an axis as a center of pivotal motion of the front fork relative to the fork bridge, more specifically, an upper mounting portion on a side of the top bridge. The resulting configuration reduces the size of a front portion of a vehicle and a steering damper.
