Abstract
A leaning vehicle has a shock tower, a frame pivotable relative to the shock tower, front left and right suspension assemblies, front left and right ground engaging members, a rear suspension assembly, and a rear ground engaging member. A pair of first stoppers is connected to one of the frame and the shock tower to limit pivoting of the frame relative to the shock tower. Each front suspension assembly has: a leg, upper and lower suspension arms, and a shock absorber having an upper end connected to the shock tower and a lower end connected to the lower suspension arm. A pair of second stoppers is connected to one of the frame and the lower suspension arms to limit leaning of the vehicle relative to vertical when the frame has pivoted relative to the shock tower and the shock absorber of one of the suspension assemblies is compressed.
Claims27
A leaning vehicle comprising:
- a frame having a front portion and a rear portion;
- a straddle seat mounted on the frame;
- a motor supported by the frame;
- a shock tower pivotally connected to the front portion of the frame, the frame being pivotable relative to the shock tower about a pivot axis between an upright position and a plurality of leaning positions;
- a first left stopper connected to one of the frame and the shock tower, the first left stopper being adapted to abut another one of the frame and the shock tower when the frame pivots left relative to the shock tower by a first angle thereby limiting pivoting of the frame relative to the shock tower toward the left;
- a first right stopper connected to one of the frame and the shock tower, the first right stopper being adapted to abut another one of the frame and the shock tower when the frame pivots right relative to the shock tower by a second angle thereby limiting pivoting of the frame relative to the shock tower toward the right;
- a front left suspension assembly and a front right suspension assembly operatively connected to the front portion of the frame;
- a front left ground engaging member operatively connected to the front left suspension assembly;
- a front right ground engaging member operatively connected to the front right suspension assembly;
- a steering assembly operatively connected to the front left ground engaging member and to the front right ground engaging member to steer the vehicle, the steering assembly having a steering column supported by the frame and a handlebar connected to the steering column;
- a rear suspension assembly operatively connected to the rear portion of the frame;
- a rear ground engaging member operatively connected to the rear suspension assembly;
- each of the front left suspension assembly and the front right suspension assembly comprising:
- a leg operatively connected to a corresponding one of the front left ground engaging member and the front right ground engaging member, the leg being rotatable about a steering axis;
- an upper suspension arm having a first end pivotally connected to the frame and a second end pivotally connected to the leg;
- a lower suspension arm having a first end pivotally connected to the frame and a second end pivotally connected to the leg, the lower suspension arm being lower than the upper suspension arm;
- and
- a shock absorber having an upper end connected to the shock tower and a lower end connected to the lower suspension arm;
- a second left stopper connected to one of the frame and the lower suspension arm of the front left suspension assembly, the second left stopper being adapted to abut another one of the frame and the lower suspension arm of the front left suspension assembly when the frame has pivoted left relative to the shock tower by the first angle and the shock absorber of the left suspension assembly is compressed by a first amount thereby limiting leaning of the vehicle relative to vertical toward the left;
- and
- a second right stopper connected to one of the frame and the lower suspension arm of the front right suspension assembly, the second right stopper being adapted to abut another one of the frame and the lower suspension arm of the front right suspension assembly when the frame has pivoted right relative to the shock tower by the second angle and the shock absorber of the right suspension assembly is compressed by a second amount thereby limiting leaning of the vehicle relative to vertical toward the right.
