Abstract
A trailing link multi-bar suspension assembly for a bicycle having improved stability includes a first arm having a first arm fixed pivot and a first arm shock pivot. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a first shock mount and a second shock mount. A wheel carrier has a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another, and a wheel mount that is adapted to be connected to a wheel. A control link has a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot.
Claims18
A bicycle comprising:
- a frame;
- a rear wheel rotatably mounted to the frame;
- a steering fork operatively connected to the frame, the steering fork being operably connected to a first arm, the steering fork rotating about a steering axis relative to the frame, the first arm being angled relative to the steering axis, the first arm having a first end and a second end, and the first arm including a first arm fixed pivot, a first arm shock pivot and a first arm control pivot;
- a shock link, the shock link having a shock link fixed pivot and a shock link floating pivot spaced apart from one another, the shock link being pivotably connected to the first arm fixed pivot at the shock link fixed pivot such that the shock link is rotatable about the shock link fixed pivot and the shock link fixed pivot remains in a fixed location relative to the first arm while the shock link floating pivot is movable relative to the first arm;
- a shock absorber having a first shock mount and a second shock mount, the first shock mount being connected to the first arm shock pivot, the second shock mount being pivotably connected to a shock connection pivot located between the shock link fixed pivot and the shock link floating pivot along a length of the shock link;
- a wheel carrier, the wheel carrier having a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another along a length of the wheel carrier, and a wheel mount, the wheel carrier first pivot being pivotably connected to the shock link floating pivot so that the wheel carrier second pivot is rotatable about the wheel carrier first pivot relative to the shock link floating pivot;
- a control link, the control link including a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot such that the control link floating pivot is rotatable about the control link fixed pivot, which remains in a fixed location relative to the first arm control pivot;
- and
- a front wheel rotatably attached to the wheel carrier at the wheel mount,
- wherein the fixed pivots and the floating pivots are arranged in a trailing configuration where each of the fixed pivots is forward of the corresponding floating pivot in a forward direction of travel of the bicycle, and wherein the shock connection pivot is closer to the shock link fixed pivot than to the shock link floating pivot, and a perpendicular distance between a central axis of an inshaft of the shock absorber and the shock link fixed pivot varies as the shock absorber is compressed and extended.
A bicycle comprising:
- a frame;
- a rear wheel rotatably mounted to the frame;
- a steering fork operatively connected to the frame, the steering fork being operably connected to a first arm, the steering fork rotating about a steering axis relative to the frame, the first arm being angled relative to the steering axis, the first arm having a first end and a second end, and the first arm including a first arm fixed pivot, a first arm shock pivot and a first arm control pivot;
- a shock link, the shock link having a shock link fixed pivot and a shock link floating pivot spaced apart from one another, the shock link being pivotably connected to the first arm fixed pivot at the shock link fixed pivot such that the shock link is rotatable about the shock link fixed pivot and the shock link fixed pivot remains in a fixed location relative to the first arm while the shock link floating pivot is movable relative to the first arm;
- a shock absorber having a first shock mount and a second shock mount, the first shock mount being connected to the first arm shock pivot, the second shock mount being pivotably connected to a shock connection pivot located between the shock link fixed pivot and the shock link floating pivot along a length of the shock link;
- a wheel carrier, the wheel carrier having a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another along a length of the wheel carrier, and a wheel mount, the wheel carrier first pivot being pivotably connected to the shock link floating pivot so that the wheel carrier second pivot is rotatable about the wheel carrier first pivot relative to the shock link floating pivot;
- a control link, the control link including a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot such that the control link floating pivot is rotatable about the control link fixed pivot, which remains in a fixed location relative to the first arm control pivot;
- and
- a front wheel rotatably attached to the wheel carrier at the wheel mount,
- wherein the fixed pivots and the floating pivots are arranged in a trailing configuration where each of the fixed pivots is forward of the corresponding floating pivot in a forward direction of travel of the bicycle, and
- wherein the shock absorber is located at least partially within a hollow portion of the first arm.
