Abstract

In a saddle-type vehicle, an engine is supported by a pivot shaft through insertion of the pivot shaft into a bracket part provided at a rear part of the engine. A center lower cross frame is so provided as to span a space between parts in left and right pivot plates on the lower side relative to the pivot shaft. The pivot shaft and the center lower cross frame are connected by a hanger member.

First claim

The invention claimed is:

1. A saddle vehicle, comprising:
a vehicle body frame including left and right main frames extending rearward from a head pipe, left and right pivot plates extending downward from rear parts of the left and right main frames, and left and right lower frames that extend along a front-rear direction at a lower part of the vehicle and each having a rear end part connected to a respective one of the left and right pivot plates;
a swing arm supported swingably around a pivot shaft that is so provided as to span a space between the left and right pivot plates;
a rear wheel supported by the swing arm; and
an engine supported by the vehicle body frame,
wherein the engine is supported by the pivot shaft through insertion of the pivot shaft into a bracket part provided at a rear part of the engine,
a cross frame is so provided as to span a space between parts in the left and right pivot plates on a lower side relative to the pivot shaft or between rear parts of the left and right lower frames,
wherein the pivot shaft and the cross frame are connected by a hanger member,
wherein the swing arm includes a left arm part connected to the pivot shaft on a left side relative to center in a vehicle width direction and a right arm part connected to the pivot shaft on a right side relative to the center in the vehicle width direction,
wherein the bracket part is connected to the pivot shaft between the left arm part and the right arm part, and
wherein the hanger member is connected to the pivot shaft between the left arm part and the right arm part.

2. The saddle vehicle according to claim 1 ,
wherein the hanger member is formed into a substantially U-shape having a left extending part, a right extending part, and a bottom part that connects one end part of the left extending part and one end part of the right extending part, and is so disposed as to be opened upward in front view,
pivot shaft attaching holes into which the pivot shaft is inserted are formed at upper end parts of the left extending part and the right extending part, and
wherein the left extending part and the right extending part are connected to the pivot shaft through insertion of the pivot shaft into the pivot shaft attaching holes between the left arm part and the right arm part.

3. The saddle vehicle according to claim 2 ,
wherein the bottom part is fastened to a fastening part provided at a center part of the cross frame in the vehicle width direction from an upper side toward the lower side by a fastening member.

4. The saddle vehicle according to claim 3 ,
wherein the bottom part is disposed at a position overlapping with the cross frame in an upward-downward direction and is fastened to the fastening part with an intermediary of an elastic member.

5. The saddle vehicle according to claim 2 ,
wherein insertion holes for fastening members fastened to the engine are each formed at an intermediate part between an upper end part and a lower end part of a respective one of the left extending part and the right extending part, and
wherein rotation of the hanger member around the pivot shaft is restricted by fastening of the fastening members inserted into the insertion holes to the engine.

6. The saddle vehicle according to claim 5 ,
wherein interval between the insertion holes on left and right sides is different from an interval between the pivot shaft attaching holes on the left and right sides, and the insertion holes on the left and right sides are located inside the pivot shaft attaching holes on the left and right sides in the vehicle width direction.

7. The saddle vehicle according to claim 1 ,
wherein the pivot shaft and the cross frame are disposed at positions overlapping with each other in an upward-downward direction.

8. The saddle vehicle according to claim 1 , further comprising:
a drive chain that is wound around a transmitting gear of the engine and a transmitting gear of the rear wheel, and is configured to transmit a driving force of the engine to the rear wheel.

9. The saddle vehicle according to claim 1 , further comprising:
a link mechanism unit that is configured to span a space between the swing arm and the cross frame,
wherein the link mechanism unit and the vehicle body frame are connected by a rear cushion.

10. A saddle vehicle, comprising:
a vehicle body frame including left and right main frames extending rearward from a head pipe, left and right pivot plates extending downward from rear parts of the left and right main frames, and left and right lower frames that extend along a front-rear direction at a lower part of the vehicle and each having a rear end part connected to a respective one of the left and right pivot plates;
a swing arm supported swingably around a pivot shaft that is so provided as to span a space between the left and right pivot plates;
a rear wheel supported by the swing arm; and
an engine supported by the vehicle body frame,
wherein the engine is supported by the pivot shaft through insertion of the pivot shaft into a bracket part provided at a rear part of the engine,
a cross frame is so provided as to span a space between parts in the left and right pivot plates on a lower side relative to the pivot shaft or between rear parts of the left and right lower frames,
wherein the pivot shaft and the cross frame are connected by a hanger member, and
wherein the hanger member completely overlaps with the pivot plates in side view.

11. A saddle vehicle, comprising:
body frame means for supporting vehicle components thereupon, said body frame means including left and right main frame means extending rearward from head pipe means, left and right pivot plate means extending downward from rear parts of the main frame means, and left and right lower frame means extending along a front-rear direction at a lower part of the vehicle, and each having a rear end part connected to a respective one of the left and right pivot plate means;
swing arm means swingably supported around a pivot shaft provided as to span a space between the left and right pivot plate means;
rear wheel means for supporting the vehicle, said rear wheel means supported by the swing arm means; and
engine means for providing motive power, said engine means being supported by the body frame means,
wherein the engine means is supported by the pivot shaft through insertion of the pivot shaft into a bracket part provided at a rear part of the engine means,
cross frame means are provided for spanning a space between parts in the left and right pivot plate means on a lower side relative to the pivot shaft or between rear parts of the left and right lower frame means,
wherein the pivot shaft and the cross frame means are connected by a hanger means,
wherein the swing arm means includes a left arm connected to the pivot shaft on a left side relative to center in a vehicle width direction and a right arm part connected to the pivot shaft on a right side relative to the center in the vehicle width direction,
the bracket part is connected to the pivot shaft between the left arm part and the right arm part, and
wherein the hanger means is connected to the pivot shaft between the left arm part and the right arm part.

12. The saddle vehicle according to claim 11 ,
wherein the hanger means is formed into a substantially U-shape having a left extending part and a right extending part, and a bottom part for connecting one end part of the left extending part and one end part of the right extending part, and is so disposed as to be opened upward in front view,
