20110162905 | STEERING MECHANISM FOR A PERSONAL VEHICLE - Steering mechanism that increases adjustability. The steering mechanism can have different gear ratios between the input rotation from the user and the output rotation on the drive wheel. The steering device will allow users to employ a pushing or pulling motion for steering instead of pushing to turn in one direction and pulling to turn in the opposite direction. Users with weaker torso strength may not be able to maintain their balance when they pull on a steering tiller. Allowing users to choose the type of motion for steering, and to supplement one motion with the other, creating flexibility and support for users with various abilities. Lastly, the steering system should not impede a user transferring into and out of the personal vehicle. | 07-07-2011 |
20110209939 | POWER STEERING DEVICE - A power steering device is mounted on a vehicle and includes a variable transmission ratio mechanism, a torque applying unit, and an applied friction torque changing unit. The torque applying unit sets an applied friction torque applied to the steering wheel and performs a control of applying the applied friction torque to the steering wheel. The applied friction torque changing unit changes the applied friction torque based on the transmission ratio of the variable transmission ratio mechanism. | 09-01-2011 |
20120024618 | BEARING ASSEMBLY FOR A POWER STEERING MECHANISM - A bearing assembly is for a mechanism including a housing and a rotatable shaft disposed within the housing. The bearing assembly includes a sleeve disposable within the housing and having an inner circumferential surface defining a bore and a radial surface extending radially inwardly from the inner surface. A bearing is disposed within the bore and includes inner and outer races and rolling elements disposed between the races, the inner race being coupleable with the shaft such that the shaft and the inner race rotate as a single unit. Further, a biasing member biases the outer race generally against the sleeve radial surface or a housing radial surface to prevent axial displacement of the outer race during shaft rotation. Preferably, a retainer couples the biasing member with the outer race to retain the bearing and the biasing member within the bore when the assembly is separate from the housing. | 02-02-2012 |
