  • Publication number: 20150239522
    Abstract: A transformation restricting mechanism is configured to change a resisting force between a first connecting member, a second connecting member, and a caliper that are configured to be displaced relative to each other. The first connecting member includes a turn supporting portion supported by a first shock absorbing device. The second connecting member includes a turn supporting portion supported by a second shock absorbing device. The turn supporting portion is supported by the first shock absorbing device closer to a first center axis than an intermediate axis which is coincident with a turning axis of a steering shaft when the vehicle body frame is in an upright state. The turn supporting portion is supported by the second shock absorbing device closer to a second center axis than the intermediate axis when the vehicle body frame is in an upright state.

  • Publication number: 20150232147
    Abstract: At least a portion of a tie rod of a steering force transmitting mechanism overlaps with a portion of a first support member or a second support member when viewed from a front of a vehicle in a fully-tilted condition in which the vehicle body frame is fully tilted in the left-right direction. At least a portion of the tie rod is disposed below a second cross member, above a first front wheel and a second front wheel, behind a front end of the first front wheel and a front end of the second front wheel, and ahead of a first axis of a first side member and a second axis of a second side member when viewed from the left or right of the vehicle when the vehicle body frame is in an upright state.

  • Publication number: 20150210338
    Abstract: A vehicle includes a center transmission plate, a first center turnable portion configured to turn about a first center turning axis extending in an up-down direction, a second center turnable portion configured to turn about a second center turning axis extending in a front-rear direction, a left transmission plate, a first left turnable portion configured to turn about a first left turning axis extending in the up-down direction, a second left turnable portion configured to turn about a second left turning axis extending in the front-rear direction, a right transmission plate, a first right turnable portion configured to turn about a first right turning axis extending in the up-down direction, and a second right turnable portion configured to turn about a second right turning axis extending in the front-rear direction. A tie rod is supported on the second center turnable portion, the second left turnable portion, and the second right turnable portion.

  • Patent number: 7976044
    Abstract: A shock absorber is provided having an exterior that looks like a two-piece structure formed with an outer tube and a separate bracket without using the separate bracket. Also provided is a straddle type vehicle having a shock absorber and a manufacturing method for the shock absorber. The shock absorber comprises a cylindrical outer tube, wherein the outer tube includes a first cylindrical part, and a second cylindrical part having an outer surface roughness greater than the outer surface roughness of the first part. The first part and the second part are adjacent each other in a longitudinal direction of the outer tube, and the second part has an equipment attaching section adapted for attaching a piece of equipment.

  • Publication number: 20090166115
    Abstract: A vehicle, such as a straddle-type vehicle, can include an engine, a catalyst and an air cleaner. The catalyst can be disposed in an expansion chamber of the vehicle. At least a part of the air cleaner can be disposed above a swing arm of the vehicle, and at least a part of the expansion chamber can be disposed below the swing arm. The air cleaner can further be disposed to the rear of a shock absorber of the vehicle. Thus, the influence of heat from the catalyst and the engine on the air cleaner can be reduced. Consequently, efficiency of air induction into the engine can be increased, thereby improving engine output.
