First Claim
Patent Images
1. A two-wheeled vehicle comprising:
- a first wheel and a second wheel rotating about shafts perpendicular to a running direction and arranged at a chassis along said perpendicular direction, a third wheel having a first state assisting said first wheel and said second wheel and a second state up to shifting to said first state, and a control means for shifting said third wheel from said second state to said first state when detecting an abnormality in running of said chassis.

Abstract
A two-wheeled vehicle able to assist wheels and keep a chassis in a stable posture at the time of abnormal operation without detracting from mobility at the time of normal operation, wherein, when some sort of abnormality is detected in the two-wheeled vehicle, an auxiliary wheel actuator disengages a projection and recess, whereby a first auxiliary wheel springs out toward a road surface together with a shank due to a biasing force of a coil spring. At the time of normal operation, the first auxiliary wheel is recessed in a step board.

8. A chassis braking system for braking a chassis, comprising
a braking means comprising a braking surface biased toward a road surface on which said chassis runs and having a first state where movement of said braking surface toward said road surface is locked and a second state where said braking surface abuts against said road surface and a control means for releasing said lock of said braking means and shifting said braking means from said first state to said second state when predetermined conditions are met.
