Abstract:
A twist-beam axle for motor vehicles, includes two longitudinal control arms, and a transverse strut interconnecting the longitudinal control arms and having over a major portion of its length a doubled-walled cross section of V-shaped or U-shaped configuration, thereby defining an inner profile and an outer profile. The inner and outer profiles support one another at least over predetermined portions to define a contact zone therebetween for receiving a friction-reducing additive.
Abstract:
The present invention intends to provide a manufacturing method of an irregular-section tubular body in which a manufacturing process is simplified, and complexing and large-sizing of an equipment, and increase of an equipment cost are avoided. In the manufacturing method of the present invention, a tubular worked body 1 sealed liquid W therein is press-formed by a press upper mold 6 and a press lower mold 3. One of the press upper and lower molds has one convex mold portion 3a to form a concave portion 1a concaved in an axis perpendicular direction at an axial part. The press-forming of the worked body to the tubular body is completed by one stroke process by using a liquid pressure increasing as decrease of internal volume of the worked body due to formation of the concave portion. Thus, liquid in the worked body is not pressurized by a pressurizing device after the press-forming.
Abstract:
A wheel suspension for a motor vehicle, particularly a rear wheel suspension, has a spring which is arranged separately from a shock absorber. The spring and the shock absorber are supported at their lower ends, by way of a common console arranged approximately transversely to the vehicle, on a longitudinal rear axle tube. An upper end of the shock absorber is swivellably held on a carrying device fastened to a vehicle body member. An upper end of the spring is disposed in a supporting device integrated in the vehicle body member.
Abstract:
An improved rear axle beam assembly for a trailing arm suspension system. The beam assembly comprises a tubular member extending transversely between the vehicle rear wheels. A pair of first and second outer sleeves, each fixed to the rearward end of a trailing arm, concentrically surround the respective outboard end portions of the tubular member. The first sleeve is fixedly attached to the one end portion of the tubular member while the second sleeve is journally mounted on the other end portion of the tubular member. A pair of first and second wheel support castings each having a collar portion defining an axial bore fixedly receiving therein the outboard end of an associated outer sleeve. An anti-roll torsion bar is axially positioned in the journaled second sleeve end portion of the tubular member. The torsion bar includes a head plate on its outboard end fastened to its associated second casting with the bar's inboard end pinned to the tubular member thereby maintaining the dimensional relationship between the left and right castings. The tubular member other end portion may rotate relative to the second sleeve upon opposite pivotal movement of the trailing arms thereby twisting the torsion bar and increasing the roll stiffness of the suspension system.
Abstract:
A vehicle includes a rear wheel suspension including a twist beam axle. The vehicle also includes upper and lower mounts for a spring and each defining a seat. The lower mount is disposed on the axle and the upper mount is disposed at a distance and parallel to the lower mount on a frame member. A first adapter is disposed within the lower mount seat and a second adapter is disposed within the upper mount seat. Each adapter defines a groove to receive an end of the spring, a support extending from the groove within an inner diameter of the spring and a wall disposed along a segment of the groove being configured to maintain a position of the spring.
Abstract:
A knee-action-type suspension is provided with an arm member, a compression coil spring, and a shock absorber. The coil spring is extended and retracted between a full-rebound state and a full-bump state in accordance with the magnitude of a load applied to a vehicle body. A wire of the coil spring includes a large-diameter wire portion, a small-diameter wire portion, and a wire diameter varying portion. The large-diameter wire portion is provided in a first portion of the coil spring, which is on the side near to a pivot. The small-diameter wire portion is provided in a second portion of the coil spring, which is on the side far from the pivot. A wire diameter of the large-diameter wire portion is greater than a wire diameter of the small-diameter wire portion.
Abstract:
The invention relates to a rear wheel suspension, which has a spring, preferably embodied as a coil spring that has a geometric spring center line and a line of action of force, the coil spring being supported in an upper and a lower spring mount. In order to reduce the forces imposed on structural elements of the rear wheel suspension, the proposal is that the spring be embodied and arranged in such a way that the line of action of force thereof has an amount of tilt during an inward deflection which is different from an amount of tilt during an outward deflection.
Abstract:
A torsion beam type suspension including a torsion beam in which arms are formed by bending both ends of a pipe material and also includes wheel installation members fixed to the arms, respectively. Portions to be inserted of the wheel installation members are inserted into open ends of the arms, and the wheel installation members are welded to the arms. The torsion beam type suspension can be produced at low cost and have high quality.
Abstract:
An axle that rotatably supports a wheel is elastically coupled to trailing arms of a motor vehicle via an upper connecting point and first and second lower connecting points, where the trailing arms are elastically coupled to a body of the vehicle. The first and second lower connecting points are positioned lower than the upper connecting point and are mutually arranged to open a gap in a front-to-rear direction of the vehicle. The first and second lower connecting points have elastic members and are arranged so that principal elastic axes of their respective elastic members intersect at a location that is outside, in the lateral direction of the vehicle, of a grounding point of the wheel. In this manner, the running stability can be increased without relying on the rigidity of the elastic members, resulting in increased freedom in design of the elastic members.
