Abstract
A stable, low speed, powered tricycle with traction steering, includes a pair of freely rotatable traction wheels and corresponding pairs of friction rollers and braking surfaces that are selectively engageable therewith to effect propulsion and steering of the vehicle. A caster wheel supports the front of the vehicle frame. This forms a tricycle rolling system that maintains stability by automatically broadening a turn to obviate tipping.
Claims8
A low speed, stable, powered vehicle with traction steering comprising:
- a frame;
- a pair of traction wheels mounted for free rotation near the rear of aid frame;
- a caster wheel system supporting said frame near the front center of said frame;
- driving system selectively engageable with one or both of said traction wheels;
- a braking system selectively engageable with one or both of said traction wheels;
- and
- a left and a right control arm for selectively moving said driving system and said braking system into engagement with one or both of said traction wheels for tractionally propelling, braking and steering said powered vehicle.
