Abstract:
A suspension bushing includes an inner cylinder, an intermediate plate, an outer cylinder and an elastic member. An axis of the inner cylinder is arranged vertically and the inner cylinder is provided with an expanded portion in an axially central region. The expanded portion is enclosed by a curved surface section formed in an axially central region of the intermediate plate. An axially outward expanded end section is provided on either side of the curved surface section. An inside annular recess and an outside annular recess are provided on an axially outward end of the elastic member. When the twist is inputted, the outer cylinder and the intermediate plate are changed relative to the inner cylinder. However, due to the provision of the expanded end section, a twist angle is increased so that the intermediate plate is hard to interfere with an end portion of the inner cylinder.
Abstract:
An axle/suspension system for a heavy-duty vehicle, in which the vehicle includes a frame that extends in a longitudinal direction relative to the vehicle. The axle/suspension system is attached to the vehicle frame via at least one hanger and includes at least one beam, which includes a first end and a second end. The first end of the beam is connected to the hanger, and the second end of the beam immovably captures an axle, which extends in a transverse direction relative to the vehicle. The beam is formed of a composite material and has a substantially constant cross section in the transverse direction to provide sufficient strength to control roll forces encountered by the vehicle during operation.
Abstract:
A front-wheel suspension system comprises a steering gear frame, a control arm mounting connector, a lower control arm, a wheel carrier, and a damping device. The steering gear frame includes a front fixing plate and a rear fixing plate integrally formed on a front side and a rear side of a power cylinder and is coupled to a vehicle body. The control arm mounting connector is fixed in a longitudinal direction under the fixing plate. The lower control arm is provided with a vehicle body side connecting member coupled to both ends of the control arm mounting connector. The wheel carrier couples to a wheel side end portion of the lower control arm, rotatably supports a wheel, and is connected to a tie rod extended from the power cylinder. A damping device absorbs vertical vibration of the wheel.
Abstract:
The invention relates to a holding element for connecting a rod (1) to the body or the chassis of a vehicle using an elastic bearing (2). Said bearing consists of at least one outer sleeve and one inner sleeve (3, 4) provided with an elastic material (5), especially a rubber material, in the annular region (6) between the two sleeves. The outer sleeve (3) is fixed to the body or the chassis, and the inner sleeve (4) is connected to the rod (1) by means of a pin (7). Said pin extends through the inner sleeve (4) and carries a securing disk (9) on its free end, which secures the elastic bearing (2) against damaging offset in the event of defective adhesion of its individual parts in the axial direction. Furthermore, the securing disk extends in the radial direction at least to the outer sleeve (3) and at least part of its outer circumference is embodied in such a way that it is oriented in an essentially concave manner away from the elastic bearing (2). Said adaptation of the securing disk (9) significantly increases the section modulus of the same, enabling a relatively thin securing disk (9) to be used.
Abstract:
A McPherson front wheel suspension arrangement for motor vehicles having a vehicle body and a spring strut arranged for each wheel. The spring strut is attached to a suspension arm which is pivotably attached to the vehicle body by an elastic bushing. The elastic bushing is essentially annular in shape and constructed around a geometric axis. The elastic bushing has an annular elastic bushing element positionally controlled in a seat in the suspension arm, and permits pivotal movement of the suspension arm. The elastic bushing element surrounds a holding element with a conical portion fixed to the lower part of the vehicle body. The conical portion of the holding element is conical in shape, narrowing in a downwards direction, and has a conical outer surface. The elastic bushing element includes a conical cavity adapted to the shape and dimensions of the conical surface of the conical portion of the holding element. The conical surfaces of the conical portion and the cavity serve as guiding surfaces during an assembly phase during mounting of the suspension arm on the vehicle body.
Abstract:
A guiding link bearing arrangement for a wheel suspension of a motor vehicle has an elastic link bearing that is supported at a carrier of the body structure of the vehicle. This link bearing is held at the free lower end of a supporting arm extending in a vertical plane and is fastened at walls of the carrier that are separated a distance from one another.

However, due to the provision of the expanded end section, a twist angle is increased so that the intermediate plate is hard to interfere with an end portion of the inner cylinder.
Abstract:
The fastening element connects two parts in a chassis of a vehicle. The fastening element has a central axle on which two opposing paired support elements of damping material are arranged at an axial distance from one another. In order to achieve an improved performance at least one of the support elements is composed of two different components and/or of different material.
Abstract:
A vehicular L-type suspension arm is provided in which a wheel support part is provided on one end part of an arm main body, and a first vehicle body side linking portion and a second vehicle body side linking portion are provided in an intermediate part and on the other end part thereof respectively, wherein an arm main body (A) includes an upper half body (AU) having an inverted U-shaped cross-section and a lower half body (AL) that blocks the lower open end of the upper half body (AU), a first vehicle body side linking portion (AF1) is formed from front and rear support plates (SF, SR) each formed by press forming a plate material, these front and rear support plates (SF, SR) have base parts (SFa, Sra) that are integrally joined to each other, the base ends thereof being welded to an outside part of the arm main body (A), extremity parts (SFb, SRb) of the front and rear support plates (SF, SR) are arranged so as to be spaced from each other in the vehicle body fore-and-aft direction, and cylindrical bush support parts (P1) are integrally formed with the extremity parts (SFb, SRb) by burring on the same axis. Thus, the first vehicle body side linking portion can be prepared at light weight and low cost while ensuring a sufficient cross-section with a joined two-piece structure.
Abstract:
An axle/suspension system for a heavy-duty vehicle, in which the vehicle has a frame that includes a pair of hangers. The axle/suspension system is attached to the hangers, and includes an axle and a pair of suspension assemblies. Each of the suspension assemblies includes an air spring and at least one spring member. The spring member includes a first attachment portion and a second attachment portion. The first attachment portion is generally rigidly connected to the hanger via a clamped connection, and the second attachment portion is operatively connected to the axle. The spring member, connected in this manner, reduces or eliminates dock walk when a cargo transfer vehicle enters the heavy-duty vehicle, and also reduces or eliminates rebound when the cargo transfer vehicle exits the vehicle. The spring member is also capable of being tuned to a predetermined stiffness that is sufficient to control heavy-duty vehicle roll forces.
