Abstract: A spring for use in conjunction with a vehicle, in particular a leaf spring (1), preferably a parabolic spring, has a single-part spring leaf (12) made of steel, in particular spring steel, having a central region (2) and two adjoining edge regions (4a, 4b), wherein the edge regions (4a, 4b) each have an end region (5a, 5b), the end regions (5a, 5b) can each be connected to a chassis in a stationary manner via a rolled eye (11), and the total length of the spring when installed on the vehicle is substantially unchangeable in all load states. In the unloaded state, the spring leaf (12) has two bending sections (13, 14), which each have a curvature with a curvature direction, wherein the curvature directions of the two bending sections (13, 14) are opposed, and the two bending sections (13, 14) merge into each other in the region of a turning point (15).

Abstract: A rear suspension apparatus of a vehicle includes: a transverse helper leaf spring connected to a rear axle and disposed in a transverse direction; and a first stopper mechanism and a second stopper mechanism contacting the transverse helper leaf spring when the vehicle moves. The rear suspension apparatus is capable of improving riding quality by using a new spring constant value generated by the transverse helper leaf spring when freight is loaded and a vehicle body frame moves downwardly, and restricting rolling movement of the vehicle when rolling is caused, thereby increasing roll stiffness and improving driving stability.

Abstract: An isolator for use in a suspension system includes a front shaft and a rear shaft. A front spring arm and a front transitional arm are mounted to the front shaft. A rear spring arm and a rear transitional arm are mounted to the rear shaft. A resilient member is mounted between the front and rear transitional arms. As forces are applied to the front and rear link arms, the front and rear shafts rotate causing the front and rear transitional arms to rotate. As the front and rear transitional arms rotate, the resilient member is compressed and expanded accordingly.

Abstract: A way to make model/experimental planes crash proof by a shock absorbing harness mounted over the body of the plane, which does not significantly affect the flying abilities and qualities of the model/experimental.The harness protects against collision with ground or other objects by strategically placing shock absorbing structures on the body of the aircraft. These structures are protruding from the overall outer dimension of the model/experimental aircraft and are the ones to first hit external objects and the ground. These shock absorbing structures are made of material that is light and provides the resiliency and cushion against the impact to the model/experimental body. The design is such that they add very little weight and drag to the model/experimental aircraft. The structures are made of thin wires and resemble an inverted question mark in its basic configuration.

Abstract: A leaf spring for the suspension of a rigid wheel axle (10) in an automotive vehicle, is pivotally but not laterally displaceably connected at a first end (15) thereof to the vehicle and is pivotally connected at a second end (16) thereof also to the vehicle. A center part (14) of the spring is connected rigidly to the wheel axle (10). The spring (6) between the first spring-end (15) and the center part (14) of the spring is straight or downwardly concave. The spring (6) between the center part (14) of the spring and the second end (16) of the spring has a double-curve configuration and, seen from the side, has a downwardly convex part (19) located nearest the center part (14) and a downwardly concave part (20) located nearest that second end (16) of the spring and adjoining the downwardly convex part (19).

Abstract: A vibration or impact isolator for use between bodies and/or structures, such as between a boat and a dock, is formed from a resilient elongated strip of resiliently flexible material of uniform lateral cross-section wherein longitudinal lateral portions of the strip are formed in the shape of open involutes extending through at least 270 degrees in the unbiased or undeformed condition. An intermediate portion or central portion of the strip between the two lateral edges, which connects the involutes, is deformable on mounting of the longitudinal strip to one of the bodies.

Abstract: A spring assembly for a vehicle having a "slipper" connection between a main leaf spring and a boot comprises a lower additional leaf spring mounted on the boot and having a hooked free end which bears upwards against the end of the main spring, and engages the hooked end of the main spring when the limit of flexing is reached.

Abstract: A first embodiment of a leaf spring suspension assembly for a tractor trailer or the like having single or multiple axles includes a first and second hanger with a camelback spring slidingly secured to an axle bracket assembly with a single torque rod extending between the forward hanger and the axle bracket assembly to stabilize same and prevent axle wind up or wheel hopping. In a multiple axle vehicle, a pivoting type equalizer is mounted between leaf springs and provides the bearing support for an end of each spring. In a second embodiment, an equalizer is supported from the chassis member by an elastomeric spring member with a shock absorber dampening the oscillation thereof. The equalizer is stabilized in the fore and aft direction by a mounting bracket and web assembly within which the mounting bracket extends, and a telescoping tube assembly vertically aligned and surrounding the shock absorber to permit vertical movement but restrict fore and aft movement of same.

Abstract: A vehicle suspension system including a mainspring connected to at least one axle of the vehicle, a hanger attached to the vehicle frame for retaining the mainspring while permitting vertical travel thereof within a predetermined range, and an auxiliary spring. A spring force multiplication mechanism connects the auxiliary spring to the mainspring so that the force exerted by the auxiliary spring is multiplied and applied to the mainspring, urging the mainspring toward the lower end of its travel range.

Abstract: A vehicle suspension system in which an auxiliary spring having a lower spring rate than the mainspring provides a resilient ride under empty or lightly loaded conditions by urging the mainspring toward the lower limit of its vertical travel. The auxiliary spring, which can be added to an existing suspension system of conventional design, extends continuously, without any stress concentrating reverse bends, from a selected point of attachment on the bottom of the frame to a hanger that retains an end of the mainspring. To accommodate differences in vehicle construction and make fine adjustments in the auxiliary spring rate, the point of attachment of the auxiliary spring to the frame can be varied or a wedge between the spring and the frame can be repositioned.
