Utility vehicle
View Patent ↗A utility vehicle has a body frame, a source of power arranged in the body frame, and an under cover for covering a lower surface of the body frame. Both ends of the under cover in the vehicle width direction or the vehicle front and rear direction are fixed to lower surfaces of a plurality of bottom frame members forming a bottom part of the body frame, and a region of the under cover facing the source of power from the lower side is raised upward. A vertically sectional shape of the raised and designated region is formed in for example an arch shape.
1. A utility vehicle comprising:
a body frame;
a source of power arranged in the body frame; and
an undercover for covering a lower surface of the body frame, the undercover having a region which directly faces the source of power from a lower side,
wherein both ends of the undercover in the vehicle width direction or the vehicle front and rear direction are fixed to lower surfaces of a plurality of bottom frame members forming a bottom part of the body frame,
and wherein the region of the undercover is raised upward, and a space is provided between the source of power and the region of the undercover which directly faces the source of power such that the region of the undercover deforms upwardly upon being heated.
2. The utility vehicle according to claim 1 , wherein
the raised region has a vertically sectional shape along the vehicle width direction formed in an arch shape.
3. The utility vehicle according to claim 1 , wherein
the raised region has a vertically sectional shape along the vehicle front and rear direction formed in an arch shape.
4. The utility vehicle according to claim 1 , wherein
the raised region has vertically sectional shapes along the vehicle width direction and the vehicle front and rear direction both formed in an arch shape.
5. The utility vehicle according to claim 1 , wherein
the raised region is formed in a partially spherical shape.
6. The utility vehicle according to claim 1 , wherein
the raised region is formed in a circular shape or an oblong shape when seen from an upper side.
7. The utility vehicle according to claim 1 , wherein the undercover has a plurality of screw insertion holes at both ends of the undercover in the vehicle width direction or the vehicle front and rear direction, and is fixed to the lower surfaces of the bottom frame members by fasteners inserted through the screw insertion holes and fastened,
wherein an inner diameter of each screw insertion hole is sized so as to have a radial play with respect to an outer diameter of one of the fasteners,
and wherein, at a time prior to heating of the undercover, surface lengths measured along the surface of the undercover in the vehicle width direction or the vehicle front and rear direction between center lines of the screw insertion holes and over the region of the undercover which directly faces the source of power are set to be greater than or equal to lengths obtained by adding the radial play to a linear distance between the center lines of the screw insertion holes.
