Embodiment Construction

[0018] The illustrated embodiments are disclosed with reference to the drawings. It should be understood, however, that the disclosed embodiments are intended to be merely examples that may be embodied in various alternative forms. The figures are not necessarily to scale and some structures may be exaggerated or minimized to show details of particular components. Specific structural and functional details disclosed are not to be interpreted in a limiting sense, but rather as a representative basis for teaching one skilled in the art how to practice the disclosed concepts.

[0019] figure 1 The power steering rattle reduction system 10 is shown in conjunction with a rack and pinion electric power assist steering (EPAS) system 12 , although other steering systems may be used. Steering system 12 has a steering wheel 14 that is rotatable by a driver (not shown) and provides steering input as indicated by arrow 15 . The steering input 15 is transferred to a steering wheel shaft...

Abstract

The invention provides a device and method for reducing rattling noise of a steering system. The rattle dampener vibrates the steering system at frequencies within the range of existing engine noise. Vibrating the steering system at a different frequency than the rattle greatly reduces rattle. The sound produced by the vibratory steering system is overshadowed by the existing sound of the engine.

Description

technical field [0001] The present invention relates to the attenuation of audible rattling from a vehicle steering system, and more particularly to masking the steering system noise by vibrating the steering system to produce audible noise in the frequency range of audible noise from other vehicle components. Background technique [0002] The steering system in a vehicle uses various shafts and gears to transmit steering input from the steering wheel to turn the wheels. The steering system uses a transmission to convert the rotational input of the steering wheel into translational motion of the wheels to the left and right. Some transmissions include rack and pinion, recirculating ball, or worm sector gear mechanisms to convert the rotational motion of the steering wheel into translational motion of the wheels. The power steering system assists the driver in steering the vehicle by increasing the steering force of the steering wheel. Because hydraulic or electric actuator...
