A mobility device for use by the elderly or disabled persons, that does not require standing, balancing or walking and is propelled by leg paddling of a user, is disclosed. The mobility device comprises a pair of base members, an inverted U-shaped member disposed between the base members, front legs extending downwardly at 45 degrees with respect to the base members with swiveling wheels, a front cross bar disposed between the front legs, such that the front cross bar and the front legs define a...

A curved leaf spring which is a first urging member surrounds an outer wheel of a second bearing, and urges, through the second bearing, a second end of a worm shaft in a direction in which the distance between the center of the worm shaft and the center of a worm wheel is shortened. A second urging member includes an annular support member received by an end surface of the outer wheel and a plurality of elastic pins extending in a direction in parallel with the axial direction of a support memb...

A steering axle for vehicles includes means for angularly displacing the axle body about a steering axis as a consequence of the relative displacement between the wheel hubs and the axle body, and vertical securing means are provided between the axle body and the bearing structure in order to hold the axle body secured vertically to the bearing structure during the lateral displacement, wherein the vertical securing means comprise an extensible member, the extension of which is correlated to the...

A vehicle drive unit, for quickly recovering a grip even if a wheel slips, in which in a slip state or at a time when the slip state is going to be generated, by pulsating a torque applied to the wheel, an angular velocity W of the wheel is changed so as to change the slip ratio S close to a slip ratio at which a friction coefficient becomes maximum, and thus, an average of a friction coefficient .mu. is enlarged and an average of a vehicle driving force F generated by a wheel is enlarged. Since...

A steering gear pinion bearing assembly adapted to support a pinion in a rack and pinion steering apparatus comprises a pinion support member including a first end, a second end and a stepped body portion; and a bearing assembly carried by the pinion support member, the bearing assembly including at least a plurality of bearings and an outer race.

A hitch mirror assembly removably mounted onto a top edge of a vehicle's tailgate, comprising a housing assembly, a mirror assembly within the housing assembly, battery-powered illumination means and a clamp assembly. The vehicle has a hitch ball for towing a trailer that has a hitch ball coupler. When the hitch mirror assembly is mounted, a person is able to view the hitch ball from inside the vehicle's cab with the mirror assembly, while backing up the vehicle to align the hitch ball underneat...

An oil pressure regulating valve of rotary type comprising a valve body and a valve spool is constructed inside a housing having a cylindrical shape. An oil supply port for supplying pressure oil fed from an oil pressure generation source is formed at a position having an offset toward one side relative to the center axis of the housing. A communicating hole in a deep inside of the oil supply port in communication with the inside of the housing is an elongate hole which is long in the direction ...

A trailer hitch for resisting inadvertent separation of a trailer tongue coupler from a vehicle's hitch ball. The trailer hitch includes a sleeve, a retainer rotatably disposed within the sleeve and including: a rod rotatably disposed within the sleeve, a displacement member coupled to the rod and extending radially therefrom, and a retaining member coupled to the displacement member and resisting inadvertent separation of the trailer tongue coupler from the vehicle's hitch ball when the retaini...

A motorcycle floorboard apparatus includes a panel that has a top surface, a bottom surface, a first lateral edge, a second lateral edge, a front edge and a rear edge. The bottom surface is removably attached to mounting supports attached to a motorcycle and the first lateral edge is positioned adjacent to the motorcycle. A plate is pivotally coupled to the second lateral edge. The plate lies within and is pivotable within a plane of the panel. The plate is selectively positionable in stored pos...

The present invention provides a method for improving cornering performance. From a given vehicle speed and lateral acceleration, in instances of a decrease in drive torque, individual wheel torque is shifted from inside wheels to outside wheels to increase vehicle yaw forces and counteract the understeer phenomenon. Similarly, in instances of increasing drive torque, individual wheel torque is shifted from outside wheels to inside wheels on a common axle to reduce vehicle yaw forces and counter...
