Abstract
A suspension system is provided for a sidecar of a motorcycle, which includes a sidecar frame and a wheel with an axle. The suspension system can include, a support frame pivotally secured to the sidecar frame, and a trailing link pivotally secured to the support frame at a leading end of the trailing link. A trailing end of the trailing link can be configured to trail behind the leading end of the trailing link relative to a direction of forward motion of the sidecar. The trailing end of the trailing link being configured to rotatably support the axle of the wheel.

A suspension system for a sidecar of a motorcycle, the sidecar including a sidecar frame and a wheel with an axle, the suspension system comprising:
- a support frame pivotally secured to the sidecar frame;
- a trailing link pivotally secured to the support frame at a leading end of the trailing link, with a trailing end of the trailing link configured to trail behind the leading end of the trailing link relative to a direction of forward motion of the sidecar;
- the trailing end of the trailing link being configured to rotatably support the axle of the wheel.
A sidecar for a motorcycle, the sidecar comprising:
- a main sidecar frame;
- a wheel with an axle;
- a tilting sidecar frame pivotally secured to the main sidecar frame;
- and
- a suspension system that includes:
- a support frame pivotally secured to the main sidecar frame;
- and
- a trailing link pivotally secured to the support frame at a leading end of the trailing link, with a trailing end of the trailing link configured to trail behind the leading end of the trailing link relative to a direction of forward motion of the sidecar;
- the trailing end of the trailing link rotatably supporting the axle on opposing sides of the wheel;
- the suspension system being configured to tilt with the tilting sidecar frame to tilt the wheel.
A sidecar for a motorcycle, the sidecar comprising:
- a wheel with an axle
- a sidecar frame;
- a suspension system that includes:
- a support frame having a first end and a second end opposite the first end, the first end of the support frame being pivotally coupled to the sidecar frame via a ball joint, and the second end of the support frame being pivotally coupled to the sidecar frame via a pinned connection;
- a pinned joint coupled to the support frame;
- a trailing link having a first trailing arm coupled to a first mounting plate having an aperture therethrough, and a second trailing arm coupled to a second mounting plate having an aperture therethrough, wherein the first trailing arm of the trailing link is configured to extend along a first side of the wheel and the second trailing arm of the trailing link is configured to extend along a second side of the wheel, wherein the axle is configured to be received through the first and the second apertures, and wherein the trailing link is pivotally coupled to the pinned joint;
- and
- a first shock absorber coupled to the first mounting plate and the support frame, and a second shock absorber coupled to the second mounting plate and the support frame;
- and
- a tilting system configured to tilt the wheel and the suspension system about an axis defined by the ball joint and the pinned connection.
