VEHICLE
A vehicle includes: a main frame having a plurality of members; and a reinforcing member that is made of a reinforced resin and that is disposed at a junction where three members out of the plurality of members intersect a point from three directions, or at a junction where one or two members intersect a point from any of three directions.
1 . A vehicle comprising:
a main frame having a plurality of members; and
a reinforcing member made of a reinforced resin and disposed at a junction where three members out of the plurality of members intersect a point from three directions or at a junction where one or two members intersect a point from any of three directions.
2 . The vehicle according to claim 1 , wherein the three members at the junction where the three members intersect a point from three directions, or a junction where the one or two members intersect a point from any of three directions are joined through the reinforcing member made of a reinforced resin.
3 . The vehicle according to claim 1 , wherein the reinforcing member has a three-dimensional structure.
4 . The vehicle according to claim 1 , wherein the plurality of members include an outer member and an inner member; and wherein the reinforcing member is disposed in a tubular hollow space defined between the outer and inner members with a clearance in which the reinforcing member nearly comes into contact with inner walls of the outer and inner members.
5 . The vehicle according to claim 4 , wherein the reinforcing member is disposed only in a two-way portion in the junction where three members out of the plurality of members intersect a point from three directions.
6 . The vehicle according to claim 4 , wherein the junction where three members out of the plurality of members intersect a point from three directions includes right and left extensions and a lower extension; and wherein a space is defined between the reinforcing member and the upper sides of the right and left extensions of the junction, the space height being substantially half of the heights of the right and left extensions.
7 . The vehicle according to claim 4 , wherein lengths of the reinforcing member that extend in the respective directions are set in accordance with strength and stiffness properties required in the junction where three members out of the plurality of members intersect a point from three directions.
8 . The vehicle according to claim 4 , wherein the junction where three members out of the plurality of members intersect a point from three directions includes right and left extensions and a lower extension; and wherein a hemispherical concave space is defined between the reinforcing member and the upper sides of the right and left extensions of the junction.
9 . The vehicle according to claim 1 , wherein the reinforcing member at the junction where three members out of the plurality of members intersect a point from three directions gradually reduces a size of the reinforcing member in the given direction.
10 . The vehicle according to claim 4 , wherein the outer member is made of a metallic material.
11 . The vehicle according to claim 1 , wherein ends of the reinforcing member are joined to metallic reinforcing members and the metallic reinforcing members are connected to each other through the reinforcing member.
12 . The vehicle according to claim 1 , wherein the reinforcing member is made of fiber reinforced plastic or carbon fiber reinforced plastic.
