摘要:
A suspension for a vehicle having a chassis rail and a longitudinal axle arranged substantially orthogonal thereto. The vehicle suspension has a primary spring, which may be a leaf spring having a first end for pivotally coupling to the chassis of the vehicle at a first primary pivot coupling, and a distal second end for pivotally coupling to the chassis of the vehicle at a second primary pivot coupling. The primary spring can be a coil spring. A secondary leaf spring has a first end for pivotally coupling to the chassis of the vehicle at a secondary pivot coupling, and a second end for coupling to the axle. The longitudinal configuration of the secondary leaf spring is arranged to be angularly displaced with respect to the longitudinal configuration of the primary leaf spring. The first primary pivot coupling and the secondary pivot coupling are arranged to be substantially coplanar.

A damping structure for providing damping and vibration attenuation includes an intermediate steel sheet (12) positioned between an upper steel sheet (18) and a lower steel sheet (20). The structure is incorporated as a part of a suspension component. The intermediate sheet is perforated with a plurality of holes (14), and a plurality of elastic strips (30) are positioned between each of the sheets when assembled. The edges of the sheets are welded, sealing viscous fluid within the structure. Alternatively, the structure can be secured by rivets. Compression on the damping structure moves the fluid through the holes, providing a damping effect.

Selectively engagable auxiliary leaf springs (38) for vertically supporting a vehicle chassis (32) on an axle assembly (22) in parallel with main suspension springs (34). Forward and rear ends (38b,38a) of the auxiliary leaf springs are pivotally attached to the vehicle chassis and the axle assembly, and pivotal movement of the forward ends (38b) is inhibited or prevented by engagement of actuator assemblies (56 or 100 or 170) to engage the auxiliary leaf springs. A control system automatically engages the actuator assemblies in response to load added to the vehicle and/or vehicle steering movement and/or rapid vehicle acceleration.

A vehicle height adjusting device includes a resilient member (11) having an outer end (A) coupled to a wheel support member (3) and an inner end (B) supported on a vehicle body (9), the resilient member (11) having a vertical resilient force and serving as a suspension component, and a load unit disposed between the resilient member (11) and the vehicle body (9) for applying a vertical bending stress to the resilient member (11) to displace the resilient member (11) for thereby varying the height of the vehicle body (9). Another vehicle height adjusting device includes an elongate resilient member (13) extending transversely of a vehicle body (9) and having opposite ends (A) coupled respectively to two laterally spaced wheel support members (3), the resilient member (13) having a vertical resilient force and serving as a suspension component, retaining members (21) supporting an intermediate portion (t₁) of the elongate resilient member (13) slidably and swingably on the vehicle body (9) at at least two spaced points (C) on the intermediate portion (t₁), and a load unit for applying a vertical bending stress to the resilient member (13) to displace the resilient member for thereby varying the height of the vehicle body (9).
摘要:
An apparatus (100) for connecting a load to a support comprises a flexible suspension arm (110) of unitary construction and restoring means (130), the suspension arm being so constructed and arranged to define at least two spaced apart members whose relative location determines the volume of a space (120) which contains the restoring means (130), deflection of the flexible suspension arm in use causing the arm to deform to alter the relative position of the two spaced apart members, thereby altering the volume of the space and so compressing the restoring means (130). The apparatus is especially suited to suspension assemblies for vehicles.
摘要:
This invention relates to a two-stage variable-rate mechanical leaf spring suspension, in which an actuator enables a sliding collar, which is placed around the leaf and the counter leaf of the leaf spring, to move lengthwise. As it moves away from the actuator, the sliding collar causes the counter leaf to move towards the leaf, thus generating the second spring rate in advance.
