Abstract:
Disclosed herein is a coupled torsion beam axle type rear suspension system that includes a coupled torsion beam axle (100) installed to extend in a transverse direction of a vehicle body, a pair of trailing arms (200) coupled to respective ends of the coupled torsion beam axle (100), and a transverse leaf spring (300) having both ends connected to the respective trailing arms (200) and a center portion connected to a body cross member (40), thereby reducing the number of parts and improving driving stability.
Abstract:
A suspension system for a vehicle is provided. The vehicle comprises a pair of rear wheels and a prop-shaft. A rear drive unit is operably coupled between the prop-shaft and the pair of rear wheels, the rear drive unit being configured to transmit torque from the prop-shaft to the pair of rear wheels. A twist-beam structure is provided having a first trailing arm and a second trailing arm. Each of the trailing arms is operably coupled to one of the pair of rear wheels. The twist-beam structure further comprising a curved beam member extending between the trailing arms, the curved beam member having a center portion disposed offset from the prop-shaft. A Watt linkage includes a first link coupled to the first trailing arm and a second link coupled to the second trailing arm.
Abstract:
The invention relates to a twist-axle that includes a cross-beam member and two trailing arms, each trailing arm rigidly secured to the cross-beam member in one of two connection regions of the cross-beam member or formed integrally with and extending from one of the two connection regions. The cross-beam member is formed from a tubular blank and has a torsionally elastic central portion and two torsionally stiff connection regions. The cross-beam member has a wall thickness that varies longitudinally along the length of the cross-beam member from the torsionally elastic central portion to each of the torsionally stiff connection regions.
Abstract:
A method of press-forming a tubular part having a cross section of an irregular shape crushes a steel tube between an upper die and a lower die in order to form a V-shaped cross section. When the curvature radius of a tip of the upper die is defined as R1, the curvature radius of a bottom portion of the lower die corresponding to the tip of the upper die is defined as R2, and the wall thickness of the steel tube is defined as t; R1, R2, and t satisfy R1+2t=R2 and 1.5t≦R1≦3t.

Abstract:
The invention relates to an axle module for a motor vehicle, the axle module being composed of two control arms which can be fixed to the body structure via a pivotal bearing, support the wheels of the axle and are connected to each other by an axle body. According to the invention, each control arm comprises a receiving element for a drive, particularly an electric motor, particularly a wheel hub motor. The receiving device is designed such that it forms the carrier for the stator.
Abstract:
A vehicle (10) comprising a vehicle body, a suspension system coupled to the vehicle body, and a plurality of wheels (16) coupled to the suspension system comprising at least one pair of wheels, each wheel of the at least one pair of wheels being located on opposite sides of the vehicle. The suspension system comprises a changeable wheel track width for the at least one pair of wheels and the wheel track width is changeable between a narrow wheel track width setting (12) and a wide wheel track width setting (14) by pivoting a suspension link (18) about a vertical axis.
Abstract:
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.
Abstract:
An apparatus for forming a beam member for a torsion beam in a rear wheel suspension system of an automobile wherein said apparatus includes top and bottom dies for forming a U-shaped or V-shaped section and an extension section of the beam member, upper and lower pad-dies coupled to top and bottom dies for forming a rectangular section of the beam member before operation of the top and bottom dies, and left and fight cams installed at both sides of a pipe so as to be horizontally inserted into the pipe by a hydraulic cylinder for maintaining inner shapes of the extension section and the rectangular section, said cams preventing both distortion and wrinkling from occurring on the rectangular section and the extension section of the beam upon operation of the top and bottom dies, thereby allowing the beam member to be formed to have different cross sections at different portions of the beam with complete symmetry, by a single process.
Abstract:
A hollow vehicle suspension beam (1) has opposed side walls formed with recesses (11) in which an axle wrap (2) is located and secured by welded jointing (12, 13) internally and externally of the opposed side walls to provide a strong joint between the beam and axle wrap. The beam may comprise at least one component (5, 6) of a generally U-shaped section the opposed limbs of which provide at least part of the opposed side walls of the beam, and the mouth of the section provides an access opening into the interior of the beam for the internal welded jointing (12) to be made at the axle wrap. One embodiment has the beam comprised of two of the U-shaped components (5, 6) disposed with their mouths opening in opposite directions to provide access to the interior of the beam for the internal welded jointing to be made at the axle wrap (2) before the mouths are closed by closure components (15, 16). Another embodiment has the opposed side walls formed in combination by the opposed limbs of a U-shaped component and the space between the plate components being closed off by closure components after the internal welded joint have been made.
