Abstract

A vehicle includes a suspension device including a right cover member that is provided at least partially between a left surface of a right brake disc and a ground contact point of a left tire and in a position located closer to the right brake disc than the ground contact point of the left tire when a body frame is in the upright state and when the body frame leans to the left, and a left cover member that is located between a right surface of a left brake disc and a ground contact point of a right tire and in a position located closer to the left brake disc than a ground contact point of the right tire when the body frame is in the upright state and when the body frame leans to the right.

First claim

The invention claimed is:

1. A vehicle comprising:
a body frame that leans to the right of the vehicle when the vehicle turns right and leans to the left of the vehicle when the vehicle turns left;
a right wheel and a left wheel that are spaced apart in a left-and-right direction of the body frame;
a suspension device that supports the right wheel and the left wheel on the body frame;
a right brake device that includes a right brake disc provided on the right wheel and a right brake caliper that brakes rotation of the right brake disc; and
a left brake device that includes a left brake disc provided on the left wheel and a left brake caliper that brakes rotation of the left brake disc; wherein
the right wheel includes a right tire and a right wheel member that supports the right tire and rotates together with the right brake disc;
the left wheel includes a left tire and a left wheel member that supports the left tire and rotates together with the left brake disc;
the right brake caliper includes a right-right brake pad that is positioned to the right of the right brake disc and a right-left brake pad that is positioned to the left of the right brake disc;
the left brake caliper includes a left-right brake pad that is positioned to the right of the left brake disc and a left-left brake pad that is positioned to the left of the left brake disc;
the suspension device includes:
a right cover member made of a synthetic resin and that is provided at least partially between a left surface of the right brake disc and a ground contact point of the left tire and in a position located closer to the right brake disc than the ground contact point of the left tire when the body frame is in an upright state and when the body frame leans to the left of the vehicle, the right cover member including a circumferential plate portion that extends radially from a lowermost portion of the right cover member and underneath the right brake disc; and
a left cover member made of a synthetic resin and that is provided at least partially between a right surface of the left brake disc and a ground contact point of the right tire and in a position located closer to the left brake disc than the ground contact point of the right tire when the body frame is in the upright state and when the body frame leans to the right of the vehicle, the left cover member including a circumferential plate portion that extends radially from a lowermost portion of the left cover member and underneath the left brake disc.

2. The vehicle according to claim 1 , wherein at least a portion of the right cover member is located between the ground contact point of the left tire and the left surface of the right brake disc that is positioned behind the ground contact point of the left tire in relation to a front-and-rear direction of the body frame when the body frame is in the upright state, and at least a portion of the left cover member is located between the ground contact point of the right tire and the right surface of the left brake disc that is positioned behind the ground contact point of the right tire in relation to the front-and-rear direction of the body frame when the body frame is in the upright state.

3. The vehicle according to claim 1 , wherein
at least a portion of the right cover member is located between the right wheel and the ground contact point of the left tire when the body frame is in the upright state and when the body frame leans to the left of the vehicle; and
at least a portion of the left cover member is located between the left wheel and the ground contact point of the right tire when the body frame is in the upright state and when the body frame leans to the right of the vehicle.

4. The vehicle according to claim 1 , further comprising a wheel rotating speed detector including a detected portion that rotates together with at least one of the right wheel and the left wheel and a detecting portion that is provided on the suspension device and that measures a rotating speed of the at least the one of the right wheel and the left wheel; wherein
at least a portion of the right cover member and/or the left cover member is located between a portion of the detected portion that rotates together with the right wheel or the detecting portion and the ground contact point of the left tire and in a position that is located closer to the portion of the detected portion that rotates together with the right wheel or the detecting portion than the ground contact point of the left tire when the body frame is in the upright state and when the body frame leans to the left of the vehicle and/or is located between a portion of the detected portion that rotates together with the left wheel or the detecting portion and the ground contact point of the right tire and in a position that is located closer to the portion of the detected portion that rotates together with the left wheel or the detecting portion than the ground contact point of the right tire when the body frame is in the upright state and when the body frame leans to the right of the vehicle.

5. The vehicle according to claim 1 , wherein
the suspension device includes a right telescopic element that supports the right wheel so that the right wheel is displaced linearly and a left telescopic element that supports the left wheel so that the left wheel is displaced linearly;
the right wheel, the right brake caliper, and the right cover member are supported at a lower portion of the right telescopic element; and
the left wheel, the left brake caliper, and the left cover member are supported at a lower portion of the left telescopic element.

6. The vehicle according to claim 1 , wherein the suspension device includes a right front telescopic element and a right rear telescopic element that support the right wheel so that the right wheel is displaced linearly and that are disposed so as to be aligned in the front-and-rear direction of the body frame, and a left front telescopic element and a left rear telescopic element that support the left wheel so that the left wheel is displaced linearly and that are disposed so as to be aligned in the front-and-rear direction of the body frame.

7. The vehicle according to claim 1 , wherein the right wheel is a right front wheel and the left wheel is a left front wheel.

8. The vehicle according to claim 1 , wherein the suspension device includes:
a right shock absorbing device which supports the right wheel at a lower portion thereof and absorbs an upward displacement of the right wheel in an up-and-down direction of the body frame;
a left shock absorbing device which supports the left wheel at a lower portion thereof and absorbs an upward displacement of the left wheel in the up-and-down direction of the body frame; and
a link mechanism; wherein
the link mechanism includes:
a right side portion that supports an upper portion of the right shock absorbing device so as to rotate about a right steering axis that extends in the up-and-down direction of the body frame;
a left side portion that supports an upper portion of the left shock absorbing device so as to rotate about a left steering axis that is parallel or substantially parallel to the right steering axis;
an upper cross portion that supports, at a right end portion thereof, an upper portion of the right side portion so as to rotate about an upper right axis that extends in the front-and-rear direction of the body frame and supports, at a left end portion thereof, an upper portion of the left side portion so as to turn about an upper left axis that is parallel or substantially parallel to the upper right axis and that is supported at a middle portion thereof on the body frame so as to turn about an upper middle axis that is parallel or subs
