JP 2002-205675 A

  In order to improve maneuverability in a motorcycle, it is preferable to lower the center of gravity of the entire vehicle. In the prior art, since the fuel tank is disposed between the rear cylinder and the rear wheel of the V-type engine, the fuel tank can be disposed low. However, the rear arm is located below the fuel tank, and there is a limit to lowering the fuel tank in order to ensure the stroke of the rear arm.

  The present invention has been made in view of the above-described conventional situation, and an object of the present invention is to provide a motorcycle that can lower the center of gravity of the entire vehicle while ensuring the stroke of the rear arm.

The invention of claim 1 includes a vehicle body frame, an engine mounted on the vehicle body frame, a fuel tank mounted on the vehicle body frame so as to be positioned above the engine, and a rear arm pivotally supported on the vehicle body frame. A motorcycle including a shock absorber disposed between the rear arm and the vehicle body frame,
The shock absorber is disposed behind the crankcase of the engine, and the uppermost portion of the attachment portion to the vehicle body frame provided in the shock absorber and the lowermost portion of the fuel tank are below the uppermost portion of the crankcase. The lowermost part of the fuel tank is located between the uppermost part of the crankcase and the uppermost part of the mounting part of the shock absorber in the vehicle longitudinal direction,
The mounting portion of the shock absorber is connected to a boss portion formed stepwise from the upper surface of the cross frame extending in the vehicle width direction with a mounting bracket interposed, and the lowermost portion of the fuel tank is connected to the uppermost portion of the mounting bracket. The fuel tank is disposed so as to cover the upper side of the shock absorber, and a space is provided between the bottom surface of the fuel tank and the uppermost part of the mounting bracket. It is characterized by that.

  According to the present invention, the shock absorber is arranged at the rear of the crankcase, and the uppermost portion of the attachment portion to the vehicle body frame provided in the shock absorber and the lowermost portion of the fuel tank are arranged from the uppermost portion of the crankcase. Located below. Thereby, the buffer and fuel tank which occupy a big weight ratio are arrange | positioned low, As a result, the gravity center of the whole vehicle can be made low and the controllability of a vehicle can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 15 are views for explaining a motorcycle according to an embodiment of the present invention.

  In the figure, reference numeral 1 denotes a motorcycle having the structure of this embodiment. The motorcycle 1 includes an engine 3, a front fork 4, a rear arm 5, a fuel tank 6, a main seat 7, and a tandem seat 8 supported by a body frame 2.

  The engine 3 is suspended and supported by a tank rail portion 16a and a rear arm bracket portion 16b of a main frame 16 which is a main portion of the body frame 2.

  The front fork 4 is supported by a head pipe 15 provided at the front end of the main frame 16 so as to be steerable left and right. A front wheel 9 is pivotally supported at the lower end of the front fork 4, and the front wheel 9 is covered with a front fender 13 attached to the front fork 4. A steering handle 10 is fixed to the upper end of the front fork 4.

  The vehicle body frame 2 includes the main frame 16 and a rear frame 34 that extends rearward and obliquely upward from the main frame 16. The rear frame 34 is a cast product of a light alloy, for example, a magnesium alloy. The rear frame 34 has a left side wall 34a, a right side wall 34a ', and a bottom wall 34b, and has a generally U shape that opens upward in a cross sectional view. An L-shaped flange portion 34c is integrally formed on the upper edge of the left side wall 34a and the right side wall 34a 'so as to expand outward. The bottom wall 34b has a front opening 34d and a rear opening 34e.

  An upper connection boss portion 34g and a lower connection boss portion 34h are formed at the front end portions of the left side wall 34a and the right side wall 34a '. These boss portions are formed on the rear arm bracket portion 16b of the main frame 16, respectively. The upper support boss part 16c and the lower support boss part 16d are fastened and fixed with bolts 16h.

  Here, the following structure is employed in order to reduce the stress generated when the rear frame 34 is attached to the rear arm bracket portion 16b at the front end portion. That is, the front end portion of the rear frame 34 has a dimension w ′ between the left and right upper connection boss portions 34g ′ and 34g ′ in a state before the rear frame 34 is attached to the rear arm bracket portion 16b. , 16c, it is formed so as to be slightly larger than the dimension w, that is, the front spreads wider toward the front. Similarly, the dimension between the left and right lower connection boss parts 34h 'and 34h' in a state before attachment is set slightly larger than the dimension between the lower support boss parts 16d and 16d.

  As described above, the front end portion of the rear frame 34 is formed to be slightly widened forward, and the front spread portion is reduced when the rear frame 34 is attached to the rear arm bracket portion 16b by bolting. The generated stress can be reduced.

  A front cross member 35 and a rear cross member 36 formed separately from the rear frame 34 are fixed to the flange portions 34c, 34c of the rear frame 34 by bolts. Furthermore, the rear end portions of the left and right flange portions 34c, 34c are joined by a cross member portion 34f formed integrally with the flange portion. By providing the cross members, the rigidity of the rear frame 34 is improved.

  The front cross member 35 is also used as a seat support bracket for supporting the main seat 7. A locking portion 35a is formed at a substantially central portion in the vehicle width direction of the front cross member 35 so as to bulge upward and to be inclined obliquely upward to the rear. A locking piece 7b provided on the bottom plate 7a of the main seat 7 is locked to the locking portion 35a.

  Further, a locking groove 35b is formed in a U shape in the locking portion 35a. A locking ring 37a provided at one end of the band 37 for fixing the tool T is locked to the edge of the locking groove 35b. A locking ring 37b provided at the other end of the band 37 is locked to a locking piece 39b formed on a battery box 39 which will be described later.

  The front cross member 35 presses and fixes the upper surface of the battery 38 housed in the rear frame 34. Specifically, the battery 38 is accommodated in a resin battery box 39 with a protective sheet 40 interposed therebetween. A damper 39a made of a rubber sheet or the like is interposed between the battery box 39 and the bottom wall 34b of the rear frame 34.

  Since the front cross member 35 for improving the rigidity of the rear frame 34 is also used as a seat support bracket, a tool fixing bracket, and a battery fixing bracket, the number of parts is increased and the structure is complicated. Can be avoided.

  In the rear frame 34, a main harness 41 formed by bundling a large number of lead wires is disposed. The main harness 41 extends in the vehicle front-rear direction along the outer surface of the left side wall 6f of the fuel tank 6 and the inner surface of the left side wall 34a of the rear frame 34. A portion 41a of the main harness 41 passing through the side of the battery 38 is housed in a two-split resin cylindrical protective case 42. The protective sheet 40 is located between the protective case 42 and the battery 38. In addition, 43a is a battery minus lead wire and 43b is a starter motor lead wire.

  Thus, since a part of the main harness 41 is accommodated in the protective case 42 and disposed between the rear frame 34 and the battery 38, the main harness 41 can be prevented from directly rubbing against the rear frame 34 and the battery 38, Damage due to wear of the magnesium alloy rear frame 34 can be prevented.

  A rubber cover 34i is attached to the front side of the flange portion 34c of the rear frame 34 from the vicinity of the battery placement portion. This suppresses heat from the engine side from being transmitted to the thigh of the rider.
