The body is an elastomeric monolith surrounding the bar and the reinforcing members. The reinforcing members have parts protruding from the body and, in the absence of external forces, are held in an operative configuration fixedly positioned relative to the bar by the body. The depressions are shaped and dimensioned such that, if the monolith were absent, each volume was occupied in form-fitting relation by a respective rigid wedge element held against movement relative to the bar, and the protruding portions of the reinforcing members were gripped about their exteriors, the reinforcing members would be securely held in said operative configuration. Methods and apparatus for forming the assembly are also disclosed.Type: ApplicationFiled: February 22, 2011Publication date: August 23, 2012Inventor: Le Lam

Patent number: 8240688Abstract: Forming a recess in an intermediate section in an axis direction of an outer peripheral face of a stabilizer bush allows the contact surface pressure between an inner peripheral face thereof and an outer peripheral face of a torsion portion to be low in a section where the recess is formed. Therefore, when the torsion portion twistedly deforms, slipping against the torsion portion starts from the intermediate section in the axis direction of the stabilizer bush, and the slipping spreads to opposite end parts in the axis direction, thus enhancing the ride comfort of a vehicle. Moreover, open ends of axially opposite end parts of the stabilizer bush, where no recess is formed, are put in intimate contact with the outer peripheral face of the torsion portion, thus preventing sand and mud from entering therefrom.Type: GrantFiled: July 8, 2008Date of Patent: August 14, 2012Assignee: Honda Motor Co., Ltd.Inventor: Yasuo Miyamoto

Patent number: 8226098Abstract: The suspension system of the present invention broadly comprises a method of retrofitting an existing torsion axle suspension carried by a frame with an air spring comprising the steps of removing an original torsion axle that was fixed to a frame from the frame and mounting the torsion axle to at least one rotatable arm such that rotation of the arm causes vertical translation of the original torsion axle. The suspension system also comprises a retrofit kit for use with a torsion axle suspension system having a torsion axle and a spindle comprising a hanger bracket adapted to be attachable to the frame, a pivot arm for mounting to the hanger bracket and adapted for rotatably supporting the existing torsion axle, an air spring, a support assembly secured to the pivot arm for supporting the air spring, and an attachment for securing the pivot arm to the support assembly.Type: GrantFiled: March 15, 2010Date of Patent: July 24, 2012Assignee: Air Suspensions, Inc.Inventors: Ervin K.

Patent number: 8220807Abstract: An antiroll device for the suspension of a motor vehicle comprises a torsion bar and two lateral links articulated to this bar and to two lateral shock absorbers. At least one of the links (9) is telescopic and includes a piston (13) mounted so it can slide in a piston tube (14) via a rod (15) connected to the hinge connecting the link to the adjacent shock absorber, the piston being mobile due to the movement of this connection and cooperating in compression with return means (17) housed inside the said tube. The return means include two compressible stop components (18 and 19) which are designed to impart to the link a progressive stiffness which increases with the amplitude of the movements of the axis of the adjacent wheel (2a), so that this wheel is substantially uncoupled from the torsion bar or coupled to it for small or large-amplitude movements respectively.Type: GrantFiled: January 9, 2009Date of Patent: July 17, 2012Assignee: HutchinsonInventors: Cédric Lorenzon, Jérôme Le Saint, Thierry Beauvilain, Christine Faure

Publication number: 20120169022Abstract: The invention relates to an anti-roll bar for a motor vehicle, the anti-roll bar being one-piece or multi-piece and being composed of a torsion rod (12) and bent rotating legs (14) on both sides, the free ends (16) of which can each be connected to a wheel suspension of the motor vehicle by means of swivel joints, wherein the anti-roll bar (11) is formed from a resin-bonded main body. According to the invention, the main body consists of a cord (4), which achieves stiffness by curing the resin. The cord (4) is introduced into a closed tool as a preform and resin is injected into the tool.Type: ApplicationFiled: September 10, 2010Publication date: July 5, 2012Applicant: IFA-TECHNOLOGIES GMBHInventors: Christian Schulz, Tom-Hendrik Braun

Publication number: 20120161412Abstract: A suspension for a rear or a front portion of a chassis for vehicles in which a pair of longitudinal stabilizer assemblies and an anti-sway stabilizer each use a same type of a stabilizer bar, with the longitudinal stabilizer assemblies pivotably connected on opposing sides of the chassis and the anti-sway stabilizer pivotably connected in transverse relation proximate an end of the chassis. The longitudinal stabilizer assemblies and the anti-sway stabilizer each include a portion of a saddle that extends around the axle and rigidly connects to the axle. A shock absorber connects between the saddle and the chassis.Type: ApplicationFiled: December 27, 2010Publication date: June 28, 2012Inventor: Frank Majerik

Patent number: 8205898Abstract: In a front wheel drive vehicle a traditional twist beam axle suffers from a short service life due to premature failures in intermediate areas between the end sections and the transitional section. A twist beam suspension is provided comprising a transverse strut (16) interconnecting longitudinal control arms (12). The transverse strut (16) may be formed from a tubular pipe. The tubular member may define a pair of tubular end sections (18), a deformed, U-shaped transitional section (20), and a pair of intermediate sections (22) between the end sections (18) and the transitional section (20). The intermediate section (22) may define a contour (28), known as a tongue. The tongue (28) enhances the flexibility in torsion and improves the stiffness in bending of the transverse strut (16). The tongue (28) may also include a concavity, to further aid in improving stiffness.Type: GrantFiled: September 4, 2008Date of Patent: June 26, 2012Assignee: Magna International Inc.Inventor: Dieter Toepker
