Abstract:
A suspension system structure is provided which permits a suspension arm to be disposed without being affected by a driven sprocket or a brake disc. A final drive case is supported on rear portions of left and right vehicle body subframes. A driven sprocket and a brake disc are coaxially disposed on the left and right of the final drive case. The driven sprocket and the brake disc are disposed on the inside of the vehicle body frame. An upper arm and a lower arm are disposed on the outside of the vehicle body frame. Support portions of the upper arm and the lower arm relative to the vehicle body frame are overlapped partly with the driven sprocket and the brake disc in a side view to provide a guard therefor.
Abstract:
A frame structure and a method of manufacturing a body frame that is divided into small assemblies to facilitate the carriage and storage of articles and individuals and the manufacturing efficiency. A body frame is divided into three, namely, a front assembly having a closed loop structure, an engine support system assembly having a closed loop structure and a rear suspension support system assembly having a closed loop structure. The front assembly and the rear suspension support system assembly are connected to the engine support system assembly to form the body frame. The small assemblies have a closed loop structure whereby the rigidity is enhanced, and the shape is also stabilized. Therefore, the accuracy management can be performed.
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 includes a head pipe mounted to the front of a body frame, a steering gear held such that it is capable of pivoting about the axis of the head pipe, side cowls each arranged at the transverse outside of the body frame, together with an opening so formed in each side cowl that it communicates with the transverse outside and inside of each side cowl. When viewed in a side view, the side cowls are lengthened up to the fore of the head pipe, and the opening is in such a position that it is level with the head pipe and overlaps with the steering gear in the fore of the head pipe. Such cowling structure permits less damages to the external appearance while providing the improvement in the lightness of banking at the time in the early stage of turning of a vehicle body.

Abstract:
A battery arrangement structure for a vehicle that concentrates a mass of a vehicle body while effectively making use of a space in the vehicle body. The engine of the vehicle is mounted on a vehicle body frame, an intake device which includes a throttle body is connected to the engine, and a battery is arranged inside a pair of left and right upper frames which constitute the vehicle body frames. The throttle body is arranged on either one of left and right sides with respect to a vehicle body center line which extends in the longitudinal direction of a vehicle body, and the battery is arranged on anotheer side with respect to the vehicle body center line.
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 mounting structure for a speed reduction device of a vehicle includes a vehicle frame, a casing mounted on the vehicle frame at a casing mounting portion, a brake caliper mounted to the casing at a caliper mounting portion, a brake disc mounted on a drive axle of the vehicle, and a clamping portion mounted on the brake caliper for applying clamping force to the brake disc. The clamping portion, the caliper mounting portion, and the casing mounting portion are positioned on a substantially straight line, and are positioned substantially parallel to the direction of braking force.

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.
