Abstract:
In the rough-terrain traveling vehicle in which rear wheels as left and right wheels are independently suspended via left and right lower arms respectively, and an anti-roll bar device is extended between the left and right lower arms, the left and right rear wheels are driven from an engine side via a chain, and the anti-roll bar device is disposed so as to extend across the inside of the circle of the chain.
Abstract:
A master cylinder for braking of reduced size and complexity and a method of making a master cylinder. The master cylinder includes a sub-tank for supplying working oil for braking, the sub-tank being integrally connected to a master cylinder main body. A first port and a second port are formed close to one another in a partition wall separating the master cylinder main body from the sub-tank. The sub-tank has a first opening and a second opening. The axes of the first and second ports in the partition wall pass through the first opening in the sub-tank, which allows tools to be inserted through the first opening to form both ports.
Abstract:
A drive chain adjustment mechanism for simplifying the tension adjustment work of a drive chain of an all terrain vehicle. The drive chain is wound around a driven sprocket connected to the rear wheels of the vehicle. The mechanism includes a case to which the driven sprocket is coupled; a cam which moves the case in a fore and aft direction with respect to a vehicle body frame; and a bolt which is located rearward of a shaft portion of the driven sprocket, and which attaches the cam and the case to the vehicle body frame. When the case is moved in the fore and aft direction of a vehicle body, the tension of the drive chain is adjusted.
Abstract:
In a vehicle of a type which does not bank a vehicle body at the time of turning, an inclination angle sensor is provided which receives the least influence of a centrifugal force at the time of turning. In a four-wheeled buggy that includes a vehicle body frame, four longitudinal wheels including front wheels and rear wheels are provided together with an engine, a fuel tank and a fuel pump. A steering shaft is connected to a steering handle with an inclination angle sensor arranged above a seat and being positioned in front of the steering shaft. Accordingly, the inclination angle sensor is hardly influenced by a centrifugal force at the time of turning.

Abstract:
A cushion mounting structure of a saddle-ride vehicle with a cushion unit having an elongated stroke length for absorbing an impact from a wheel. The structure includes an upper and a lower arm constituting a suspension arm. The arms are tiltably connected to left and right portions of a support frame, the rear wheels being supported on the suspension arm. One end of a cushion unit is supported on the vehicle body frame, while the other end is supported on an upper arm by a link member and a push rod. The first end of the cushion unit is positioned inside the vehicle body frame in the vehicle body width direction, the second end of the cushion unit is positioned outside the vehicle body frame in a width direction, and an axis of the cushion unit extends in the longitudinal direction of the vehicle while intersecting the vehicle body frame.
Abstract:
A running board for an all-terrain vehicle includes structure for substantially blocking snow, mud and the like from landing onto the running board during operation, and also for blocking engine heat from excessively warming the feet of a rider. In a running board including a step portion which is positioned on a side of a powertrain unit having an operation pedal in a side portion thereof, a partition is provided between the engine and the step portion, the partition including an insertion opening portion into which the operation pedal is inserted. The partition can be made wider since the operation pedal is inserted into the insertion opening portion blocking snow, mud and the like from coming through a space between the running board and the engine. The partition plate also tends to block engine heat from excessively warming the feet of a rider.
Abstract:
A brake master cylinder and a motorcycle including the brake master cylinder. The master cylinder has a main body and a sub-tank extending parallel to the main body. The master cylinder is arranged on the motorcycle to be generally perpendicular to the road surface, and the sub-tank is aligned with an axis of the main body. The main body and the sub-tank are integral and the sub-tank is disposed outwardly from the vehicle with respect to the axis of the main body. The resultant shape of the master cylinder is an elongated body which does not add to the width of the vehicle, and uses minimal space. The main body includes a mounting seat for mounting a brake hose, the mounting seat being arranged on the main body so as to extend perpendicularly to the axis of the main body.
Abstract:
A vehicle has an engine and a fuel tank, which is located above the engine, mounted on a vehicle-body frame. A fuel pump, which supplies fuel is spaced-apart from the fuel tank and is located below the fuel tank and in front of the engine. Further, a center of the fuel pump in the vehicle-width direction is located so as to overlap a vehicle-body center line which extends in the longitudinal direction of the vehicle body. Additionally, the fuel pump is mounted on lower main frames, which are positioned below the vehicle body.
Abstract:
A cowling structure for a saddle-ride type vehicle for cooling an engine and providing a windshield for a rider. The cowling structure includes a seat for a rider to sit thereon, the seat is arranged behind and above an engine suspended from a vehicle body frame. An under cowl covers at least part of a lower portion of the engine. The under cowl is formed to cover at least part of a side surface of the engine. A guide portion is provided in an upper portion of the under cowl, the guide portion extending inward in a vehicle width direction and toward the side surface of the engine. An opening is provided in front of the guide portion, the opening introducing a flow of air into the under cowl. The guide portion has a slope surface which slopes downward from the front to the rear of the vehicle.
