Patent number: 11760144Abstract: A wheel suspension for a motor vehicle includes a wheel linkage. The wheel linkage has a bearing region and a spring element. The wheel linkage has a first linkage arm with a first connecting element. A second linkage arm has a second connecting element. The second linkage arm has a first longitudinal region having the second connection element and a second longitudinal region attached to the first longitudinal region and disposed between the bearing region and the first longitudinal region. The second longitudinal region is offset in relation to the bearing region and the first longitudinal region downwardly in a vertical direction of the motor vehicle in an installation position of the wheel suspension.Type: GrantFiled: August 4, 2020Date of Patent: September 19, 2023Assignee: Daimler AGInventors: Martin Gottwald, Sven Mueller, Christian Mosler, Julian Schaefer

Patent number: 10807426Abstract: The invention relates to a multi-link rear suspension for a motor vehicle, having at least one transverse leaf spring arranged on the motor vehicle to extend in the transverse vehicle direction and having ends which operatively act on left and right wheel carriers to cushion a vehicle structure of the motor vehicle with respect to the wheel-carriers. The transverse leaf spring also serves as a stabilizer, thereby replacing dedicated stabilizer. In order to provide a multi-link rear suspension which is optimized in terms of structural space and which is lightweight, the multi-link rear has exclusively transverse links for guiding the wheel-carriers.Type: GrantFiled: September 26, 2018Date of Patent: October 20, 2020Assignee: Ford Global Technologies, LLCInventors: Alberto Girelli Consolaro, Paul Zandbergen, Daniel Mainz, Friedrich Peter Wolf-Monheim, Thomas Gerhards, Ralf Hintzen, Rainer Souschek, Brian Chen

Patent number: 9073400Abstract: A motor-vehicle multi-link suspension system includes, for each wheel, two lower transverse arms and a substantially longitudinal or inclined lower arm, each having one end pivotally connected to a respective wheel support and the opposite end pivotally connected to the motor-vehicle structure. A leaf spring is arranged transversally with respect to the longitudinal direction of the motor-vehicle. The leaf spring is supported by elastic supports arranged symmetrically at intermediate positions between the center of the leaf spring and the ends thereof. Ends of the leaf spring are pivotally connected to upper parts of the two wheel supports. Two jack-type shock absorbers have opposite ends swingably connected to the respective wheel support and the motor-vehicle structure. The end portions of the leaf spring also fulfill the function of triangular upper transverse arms of the multi-link suspension. Preferably the leaf spring is made of a composite material.Type: GrantFiled: May 2, 2014Date of Patent: July 7, 2015Assignee: FIAT GROUP AUTOMOBILES S.p.A.Inventors: Eugenio Perri, Bruno Martina

Patent number: 8668189Abstract: A spring is formed of a relatively thin sheet of spring material which is constricted and held in place at each end forming a bell curve being located between two substantially planar members. As additional compressive force is applied in the vertical direction, the curve then compresses and starts to form sine waves. The greater the force, progressively higher the wave frequency with lower amplitude would form. When the force is removed, the flexible material returns to its original shape. The force needed to shift the curve (increase the number of waveform) increases at an exponential rate, as opposed to the linear rate of most normal springs. The maintenance force of new stable state is considerable less than the threshold force. Such a relatively flat spring with an exponential spring rate and self dampening through phase change has a number of useful applications for automotive and industrial use.Type: GrantFiled: February 7, 2011Date of Patent: March 11, 2014Inventor: Walker Lee Guthrie

Patent number: 8540224Abstract: A spring is formed of a relatively thin sheet of spring material, which is constricted and held in place at each end forming a bell curve being located between two substantially planar members. As additional compressive force is applied in the vertical direction, the curve then compresses and starts to form sine waves. In an improved embodiment of the present invention, the sine wave spring is formed in a wedge shape, so that it is gradually taller and more progressive. This embodiment has been tested for use as a trailer spring with positive results. This wedge-shaped sine wave spring provides even more advantages over the Prior Art. The wedge-shaped prototype illustrates also how the present invention may be expanded to other shapes, in order to alter the spring characteristics, and also for packaging and other concerns.Type: GrantFiled: November 16, 2011Date of Patent: September 24, 2013Inventor: Walker Lee Guthrie

Patent number: 5860637Abstract: Rubber shock absorber systems for use between the frame and equalizer bar of a construction vehicle usually fail to withstand high temperature environments. A metallic spring assembly is provided which is capable of high flexibility and durability. The spring assembly includes a first arcuate spring member and a second arcuate spring member adjacent to and inverted from the first spring member. First and second arcuate plate members are positioned against the first and second spring members respectively, and have a larger bend radius so that a clearance is created therebetween. A bolt with a plate nut threaded thereon is provided to connect the spring assembly and to provide a preload. During compressive loading, opposing end portions of the first and second spring portions are deformed to provide an energy absorbing system. The flexibility and durability of the spring assembly is controlled by the bend radius, thickness, and length of the plate members.Type: GrantFiled: December 24, 1996Date of Patent: January 19, 1999Assignee: Caterpillar Inc.Inventor: Stephane L.
