A motor-driven power steering device includes an electric motor for generating assistive torque which is applied through a ball screw mechanism to a steering gear mechanism to reduce manual steering forces applied by the driver to steer a motor vehicle. The motor-driven power steering device comprises a rack-and-pinion steering gear mechanism for converting the rotation of a pinion shaft to axial movement of a rack shaft, an electric motor for generating assistive torque to be applied to the rac...

A three-wheeled vehicle having a pair of front wheels and a single rear wheel is provided with a roll-related reactive system. The roll-related reactive system provides braking of at least one of the front wheels independent of braking initiated by an operator of the vehicle.

In a valve for a hydraulic power steering, comprising a first valve element and a second valve element which from a central position can be rotatably displaced relative to each other to a limited extent in the one or other direction in order to generate a steering assistance, it is provided that one of the valve elements can be rotatably displaced from a neutral position into the one or other direction relative to an associated shaft and that a coupling mechanism is provided which limits the dis...

The present invention relates to a tilt device for a vehicular steering column, which permits a lock slider cooperating with an operating lever to regulate pivoting of a movable gear by simplifying the engagement structure between the movable gear and a fixed gear to reduce the number of parts and enhance assembling ability, thereby reducing manufacturing cost. The tilt device of the invention also minimizes the operating force of the operating lever while elevating the coupling force between th...

A support apparatus for a steering column of an automotive vehicle. The support apparatus comprises an upper and lower brackets through which a lower housing of the steering column is installed to a vehicle body. The lower housing is releasable from the vehicle body through first and second releasing mechanisms. The second releasing mechanism includes a part defining a through-hole through which the front end section of the lower housing is projectable forward. An engaging and releasing device i...

An engine compartment cover for a work machine includes left and right-hand side covers for covering the sides of an engine, and a hood for covering the top of the engine. The engine compartment cover serves to enclose the engine and demarcate an engine compartment and is capable of suppressing the noise at the operator's ear level caused by the engine operating noise passing through the engine compartment cover as far as possible, whereby the level of quietness in the operator cab can be improv...

A motor powered scooter for supporting a standing rider has an improved torsion acting shock absorbing mount for the cantilevered shock absorbing support of at least one of the scooter wheels from the frame. At least one torsion acting shock absorber is utilized. In a preferred embodiment, the torsion acting shock absorber includes a square sectioned metal tube, a correspondingly square sectioned metal shaft, and confined compressible rubber rods acting there between. The torsion acting shock ab...

A pivoting cage cargo bed extender is pivotally mounted to the D-pillars of a pick-up truck to be pivotally movable between a forward position and a rearward position. In the rearward position, the pivoting cage serves as a supplemental tailgate structure that rests on the open tailgate to extend the operative area of the cargo bed. The pivoting cage is formed of individual segments that are hinged together and separable at the center into two halves that are each collapsible into a stowed posit...

An ATV is described with a frame and at least three wheels suspended from the frame. At least one of the wheels is a front wheel and at least one of the wheels is a rear wheel. The front wheel defines a front axis and the rear wheel defines a rear axis. A power unit drives at least one of the wheels on the frame. A straddle-type seat is provided with a main seat portion for a driver and a secondary seat portion, rearward of the main portion, for a passenger. A back rest is also provided for the ...

A failsafe steering device for a steer-by-wire system includes a main Electronic Control Unit (ECU) that detects manipulating states of a main steering wheel and a rack mechanism via a plurality of sensors, actuates a reaction motor that provides the reaction force to the main steering wheel in relation to a driver's steering force, and controls a steering motor that executes the steering by actuating the rack mechanism. The failsafe steering device further includes a battery providing power to ...
