Patent number: 8342547Abstract: A component or assembly for vehicle suspension comprising inter alia, a hub carrier supporting a wheel carrier, a bracket and one or more of support bodies interposed between the hub carrier and the bracket. The support bodies are supported with respect to or by the base suspension. The one or more support bodies each has a predetermined first rigidity in a first direction and a second rigidity in directions normal to the first direction, wherein the first direction is oriented such that it intersects a longitudinal and vertical plane of the vehicle and wherein the second rigidity is lower than the first rigidity.Type: GrantFiled: September 25, 2009Date of Patent: January 1, 2013Assignee: M. B. Gerrard V/Miles B. GerrardInventor: Miles Barnaby Gerrard

Patent number: 8317208Abstract: Vehicle suspension having arms (6) and (7) for each wheel (14) and (15) respectively, each arm (6) having more than one sprung strut (18) and (19) of which two such struts each operates exclusively between two different arms. Each arm's rotational axis (28) and (38) respectively intersects a vertical longitudinal plane through the center of road contact with the wheel at a point (45) and (46) respectively on a straight lines (47) and (48) respectively between the center of contact with the road and a point at or near the anticipated center of gravity (49) of the suspended mass projected onto the plane. Preferably, the vehicle transmission avoids applying a moment about the arm's rotation axis, braking is attached to the arm and steering linkage is passed through or near the arm's axis of rotation.Type: GrantFiled: May 20, 2009Date of Patent: November 27, 2012Inventor: Alan Bryn Bird

Patent number: 8308175Abstract: Provided is a tubular torsion beam for rear suspensions of vehicles, which is produced according to a more durable design capable of improving roll stiffness and roll strength of the tubular torsion beam. The tubular torsion beam is produced by pressure-forming a tubular steel member through hydroforming such that the tubular torsion beam has a cross-section varying along an entire length thereof, with opposite ends having a closed cross-section and mounted to respective trailing arms, a middle portion having a V-shaped open cross-section, and a transitional portion having a varying cross-section and connecting the middle portion to each of the opposite ends. During the process of manufacturing the tubular torsion beam, the opposite ends of the tubular steel member are fed using respective axial punches of a hydroforming machine, so that the opposite ends are thicker than the middle portion.Type: GrantFiled: July 24, 2008Date of Patent: November 13, 2012Assignee: PoscoInventors: Han Ho Choi, Yeon Sik Kang, Sung Ho Park, Jin Ho Oh, Keun Hwan Kim

Patent number: 8282115Abstract: A suspension system for use on off-road trailers may be an independent air suspension system that may provide ample wheel travel and stability to keep the wheels on the ground through rough and uneven terrain. Conventional suspension systems may lack adequate wheel travel, may bounce too much, or may not be soft enough. The suspension system of the present invention may use an air bag to normalize the suspension for varying weights of the trailer load, allowing proper suspension for both heavy and light loads.Type: GrantFiled: May 7, 2010Date of Patent: October 9, 2012Assignee: Terrasport, IncInventor: Scott P. Stephani

Publication number: 20120211957Abstract: A preferred embodiment of the present invention includes a triple torsion axle system and kit with various features to help reduce or prevent damage that otherwise may occur with large loads. For example, each axle assembly includes larger diameter caps on the ends of each torsion bar to prevent the bar from pulling out of its outer tube during high side loads. In another example, the outer end of the torsion bar has a rounded surface that is fixed to a swing arm so as to better equalize the stress around the weld joint. Additionally, the triple torsion axle is configured such that when the vehicle is unloaded, the middle axle assembly supports more weight than the two adjacent axle assemblies. However, when the vehicle is loaded, all three axle assemblies provide similar support to the vehicle.Type: ApplicationFiled: February 14, 2012Publication date: August 23, 2012Inventors: Larry Revelino, Leonard Bailey, Tomothy D. Schultz, Emmanuel Camus

Patent number: 8226101Abstract: A torsion system (20) comprising a housing (24) adapted to be secured to a structural portion of a vehicle. A shaft (23) has a core portion (32) accommodated in the housing (24) and defines concavities (34) in the core portion (32). The shaft (23) has a connector end (30) connected to a crank arm. The connector end (30) protrudes out of the housing (24). Elastomeric members (25,25?) are received in the concavities (34) of the shaft (23). The elastomeric members (25,25?) each have a geometry so as to at least partially fill the concavities (34) and contact an inner surface of the housing (24), whereby a rotation of the crank arm results in a deformation of the elastomeric members (25,25?).Type: GrantFiled: November 20, 2006Date of Patent: July 24, 2012Assignee: Systeme Nenuphar Inc.Inventor: Yves Lariviere
