Abstract: This invention pertains to induced vibrations and the dampening of these vibrations in the motor means. Vibrations induced by rotating a shaft having eccentric weights thereon have been used to produce all kinds of shaking apparatus including large car shakers in which the induced force may be much as eight thousand two hundred pounds. These vibrations may be as much as five thousand six hundred vibrations per minute and may be employed in hugh bins and hoppers in which the capacity is as great as one hundred fifty thousand pounds. Vibrators using air, electric or hydraulic motors can be tuned or adjusted to provide the desired results. Most of these vibrators using a tuned motor may be temporarily or permanently attached. Conventional motor driven vibrators, as far as is known, transmit the vibrational forces into the shaft of the motor. Said motors, which are usually conventional off-the-shelf units have their rotor bearings designed for rotary motion rather than combined with a vibratory force.

The resilient pads are configured and positioned to attenuate along the direct line of travel vibrations which are transferred to the seat through seat support frame members normally juxtaposed to a main seat support rails which is connected to the vehicle chassis. The interfacing pads intercept and dampen vibration paths which are normally transferred by rigid frame member interconnections.

Abstract: A strut rod mounting assembly of the type which utilizes a pair of resilient bushings disposed on opposite sides of a vehicle frame member. A terminal end of the strut rod passes through a frame member opening and openings in the bushings with an alignment cup interposed between each bushing and the frame member. Each alignment cup includes a first cylindrical flange closely received in the frame member opening for piloting the cup itself and a second cylindrical flange closely received over an axial portion of the associated bushing outer periphery. This second cylindrical flange acts to pilot the associated bushing and thereby eliminates the need for internal piloting and pivoting means which adds high load forces on the bushing inside diameter, causes bushing pinching and abraiding and reduces the mounting assembly overall life.
