RAIN, SNOW, MUD, SAND & SIDE HILLS… WESLL GS ADVENTURE QUADS
PATENTED LONG TRAVEL LEANING SUSPENSION TECHNOLOGY
WESLL has developed the first active long travel leaning suspension technology. The active suspension system ensures optimal spring load and damping in all situations on and off road. Active camber control provides predictable rapid direction change without the imbalance moments associated with two-wheel vehicles. WESLL vehicles do not operate within conventional design parameters and therefore are not limited to a particular set design envelope.
To change direction the motorbike operator must persuade the vehicle to move out of a state of equilibrium and roll or lean in the desired direction of travel. This is accomplished by steering/turning the front wheel counter to the desired direction; countersteering the front wheel induces a gyroscopic precession torque that loads the front suspension to roll the vehicle in the desired direction. Control of the motorbike is dependent on this precession torque response and the traction of the single front wheel. Depending on the speed of the vehicle, surface conditions, and rate of roll, the motorbike can experience moments of traction loss and instability during direction change or minor wheel deflection events. Motorbike instability safety issues are especially prevalent in high-speed off-road riding, and are the single reason most Off-road racing organizations including DAKAR have placed limits on the engine displacement of motorbikes – not to exceed 450cc.
Four-wheel WESLL quads:
In contrast to the motorbike, the active suspension technology of the WESLL quad initiates roll by applying a camber torque to all four wheels through center mass c.g. shift. This method of changing trajectory increases vehicle control and safety especially at higher speeds where reaction times are shortened and control is paramount. Individual wheel instability moments have a negligible effect on the stable-trim-state of the 4-wheeled system. The ability to initiate direction change through center mass c.g. shift provides the additional force necessary to effect precise control over the combined gyroscopic forces of the four-wheeled design. The system’s ability to manage large suspension events at speed provides an exceptionally smooth ride resulting in reduced operator fatigue and improved awareness. WESLL active long travel suspension technology provides the operator with new tools to tackle whatever obstacles he may be confronted with – On or Off-road: rain, snow, mud or side hills, the quad’s performance is without equal.
