Patent number: 7364223Abstract: To provide a cab supporting structure capable of supplying a protection function with a simple configuration by using an attenuation mechanism commonly used for a controlled vehicle for protecting the cab or an operator from high impact force acting on the cab while absorbing vibration and shock on the cab in a normal condition when a construction machine falls down. The cab supporting structure is provided with an attenuation mechanism elastically supporting a cab against a frame. A regulation member, only when certain displacement is generated in the cabin the extension direction of the attenuation mechanism, regulating this displacement is provided separately from this attenuation mechanism. The regulation member regulates the displacement of the cab before a stroke end of the attenuation mechanism. Upon arranging a work equipment on the frame, the regulation member is provided at least at the opposite side of the work equipment.Type: GrantFiled: July 31, 2006Date of Patent: April 29, 2008Assignee: Komatsu Ltd.Inventors: Tadashi Mori, Ryo Kondo

Patent number: 7338034Abstract: An elastomeric spring including an elongated elastomeric body defining a longitudinal axis for the spring and having first and second longitudinal ends. An outer surface of the elastomeric body extends between the first and second ends and has four generally planar sides, with each planar side of the outer surface being disposed to one side of and generally parallel to the longitudinal axis of the spring so as to reduce radial bulging of the spring in all directions when an axial load is applied to the spring. The outer surface of the elastomeric body further includes four angled corner sections extending between the first and second ends of the elastomeric body and disposed a substantially common distance from the longitudinal axis of the spring. One corner section is disposed between any two adjoining sides on the outer surface of the elastomeric body.Type: GrantFiled: September 27, 2005Date of Patent: March 4, 2008Assignee: Miner Enterprises, Inc.Inventors: Paul B. Aspengren, Steve R. White, Erik D. Jensen, Adam J. Merges, Michael L. McGuigan

Patent number: 7290322Abstract: A stabilizer bar for an automotive vehicle includes a stabilizer bar, and a generally ring shaped first mechanical stop mounted onto and extending about an outer diameter of the stabilizer bar. The first mechanical stop is crimped in place onto the stabilizer bar such that the first mechanical stop is positioned within a groove formed within the outer diameter of the stabilizer bar as the first mechanical stop is crimped onto the stabilizer bar, whereby the first mechanical stop is retained within the groove to prevent movement of the mechanical stop along the stabilizer bar.Type: GrantFiled: September 1, 2004Date of Patent: November 6, 2007Assignee: Automotive Components Holdings, LLCInventors: Haimian Cai, Xinjian Fan, Mikhal el Arculli

Publication number: 20070138717Abstract: An impact absorber is provided for absorbing impact forces especially in case of a collision of a motor vehicle. The impact absorber includes an inner tube (1), which can be pushed into an outer tube (2) in a telescopic manner and which is closed with a bottom plate (3) at its free end projecting from the outer tube (2). Starting from the bottom plate (3) in the direction of the longitudinal axis (4) of the impact absorber, a gas space (5) filled with pressurized gas and a first, a fluid-filled liquid space (7), which is separated from the gas space (5) by a wall (6) displaceable in the inner tube (1), are arranged in the interior of the inner tube (1). The liquid space (7) is in connection through a throttle element with a second, fluid-filled liquid space (13), which adjoins the first liquid space (7) in the direction of the longitudinal axis (4) and is closed by a piston (9) fixed in the outer tube (2) towards the free end of the outer tube (2) in a liquid-tight manner.Type: ApplicationFiled: November 29, 2006Publication date: June 21, 2007Inventor: Guido STEINBACH

Patent number: 7178796Abstract: The present invention provides a rate stiffening jounce bumper assembly, including a cup member having a large-headed mushroom stud which is inserted into the cup-shaped member and overmolded with an elastomeric bumper material. The head portion of the mushroom stud forms a shelf against which the bumper material is compressed such that the head portion effectively shortens the bumper spring thereby providing a stiffer spring rate to be obtained with a taller jounce bumper assembly.Type: GrantFiled: November 29, 2004Date of Patent: February 20, 2007Assignee: Freudenberg-NOK General PartnershipInventors: Mickey L. Love, Laurie Jean Schleck
