Abstract
A tilting vehicle includes a frame and a front wheel coupled to the frame. A rear wheel is coupled to the frame and positioned rearward of the front wheel in a longitudinal direction. A seating area includes at least one seat positioned to support a rider between the front wheel and the rear wheel. A gyroscopic rider assist device is provided within an enclosure behind the seating area and above the rear wheel.
Claims22
A tilting vehicle comprising:
- a frame;
- a front wheel coupled to the frame;
- a rear wheel coupled to the frame and positioned rearward of the front wheel in a longitudinal direction;
- a seating area including at least one seat positioned to support a rider between the front wheel and the rear wheel;
- and
- a gyroscopic rider assist device provided within an enclosure behind the seating area and above the rear wheel, the gyroscopic rider assist device including:
- a gimbal support frame fixed with respect to the frame,
- a gimbal rotatably supported by the gimbal support frame for rotation about a roll axis, and
- a flywheel supported for rotation about a flywheel axis by a bracket, wherein the bracket is rotatably supported by the gimbal about a precession axis.

A tilting vehicle comprising:
- a frame;
- a front wheel coupled to the frame;
- a rear wheel coupled to the frame and positioned rearward of the front wheel in a longitudinal direction;
- a gyroscopic rider assist device operable to output a corrective moment on the vehicle in response to an input from an actuator;
- and
- a clutch provided between the actuator and the gyroscopic rider assist device to selectively deactivate the gyroscopic rider assist device upon transition from a first condition of the vehicle to a second condition of the vehicle,
- wherein the gyroscopic rider assist device includes
- a gimbal support frame fixed with respect to the frame,
- a gimbal rotatably supported by the gimbal support frame for rotation about a roll axis, and
- a flywheel supported for rotation about a flywheel axis by a bracket, wherein the bracket is rotatably supported by the gimbal about a precession axis.
