Abstract: A tensioning device for attachment to a vehicle suspension system reduces play at ends of a pan hard bar (track bar) of the vehicle suspension system, remedying instabilities that can occur in vehicle suspensions. The device can include a bracket clamped to the pan hard bar at a point between the ends of the pan hard bar, or may be otherwise mounted to a bracket formed on the pan hard bar in OEM installations. The other end of the device is secured to the frame or the axle of the vehicle, generally near an end of the pan hard bar. The device is pre-tensioned to apply force at the ends of the pan hard bar, and includes a damping plunger to also damp forces that vibrate the ends of the pan hard bar, further loosening attachments. The tension is field-adjustable and may be tuned for various applications.

Abstract: A torque rod, in which a front rubber and a rear rubber are respectively disposed at front and rear sides of a partition of a case fixed to a sub-frame and in which a pipe portion of a rod connected at a front end portion thereof to a power train passes through the front rubber, the partition, and the rear rubber and is coupled to an end plate, may include an attenuation device configured to cause flow of a liquid therein according to a load or vibration transferred from the rod, wherein the attenuation device is separably mounted between the rod and the end plate.

Abstract: Disclosed is a dog-bone type rear roll rod in which a body bracket, which is fixed to a vehicle body, and front and rear rubbers, which are disposed at front and rear sides of the body bracket, respectively, are connected together through an inner pipe and fastened to a rod by means of a fastening member, the dog-bone type rear roll rod including: an extrusion plate which has a through hole formed such that the inner pipe penetrates a center of the extrusion plate, has a width length greater than a width length of the rod, and is press-fitted between the rod and the front rubber.

Abstract: A control arm for use in a vehicle suspension. The control arm includes a first connection, the first connection configured to secure the control arm to a first external device and a second connection, the second connection configured to secure the control arm to a second external device. An external force expands or contracts the distance between the first connection and the second connection within predetermined limits. The control arm also includes a mechanical bias, where the mechanical bias returns the distance between the first connection and the second connection to a set free length when the external force is removed.

Abstract: A mechanically adjustable elastomer bearing based on a correspondingly arranged spring element whose spring stiffness can be adjusted or pretensioned individually by deformable elastomer bodies or elastomer layers. The deformation of the elastomer layers, and thus of the spring elements, is achieved by a pressure-generated device which is fully integrated into the spring element. The elastomer bearing are particularly suitable for use as bearings in rotor and gearbox for large wind turbines, but can also advantageously be employed in machine and vehicle construction, and in particular package clutches.

Abstract: A process for producing a ceramic honeycomb structural body includes the steps of: producing a ceramic honeycomb fired body by shaping a ceramic material by extrusion, and drying and firing the shaped body; removing a peripheral portion of the ceramic honeycomb fired body by working; and forming an outer wall portion around an outer peripheral surface of the worked ceramic honeycomb fired body.

Abstract: A link asssembly includes a jointed arm terminating in a barrel portion at one end and a collar portion at the opposite end. The barrel portion is mounted to a control arm by a fastener. The collar portion receives a tubular stabilizer bar. During operation, the jointed arm provides a working angle large enough to accommodate the movement between the stabilizer bar and the link assembly.

Abstract: An independent wheel suspension system for a motor vehicle includes a trailing arm (70) mounted for pivotal resilient movement through pivotal connecting members (72, 74), carried in the vehicle chassis (78). Resilient pivotal connection to a strut assembly (10) is effected through ball stud (56). The configuration and positioning of the trailing arm (70) and its mountings (72, 74, 56) elevates the vehicle roll center and reduces toe-out of the vehicle wheels during recession. An economical stamped support structure (20) having a spindle support member (36) and a strut support member (38) is utilized in the system. A combination spring seat and steering arm (22) is fixed to the top of the strut support member (38).

Abstract: A vehicle suspension of a type generally disclosed in U.S. Pat. No. 3,801,086, especially adapted to drop-frame vehicles, wherein a torque beam is formed to straddle the frame of the vehicle and be attached through a resilient bushing to the web of the frame, all of which gives a controlled spring to the vehicle as well as an accommodation for the tilting of the axle about a longitudinal axis of the vehicle.

Abstract: The reciprocal device is interposed between an end of of a torsion bar and the swing arm of a suspension system for a front wheel of a vehicle so as to reciprocate in both the extensional and intensional directions with the stroke thereof being limited to a length remarkably smaller than the maximum amplitude of the ends of the torsion bar, in response to the movement of the torsion bar. The device has a resisting force that gradually increases while the device is in the advance process from the neutral position to the end of the both strokes but substantially naught when it is in the return process from the end of the stroke to the neutral position.

Abstract: An anti-sway mechanism for motor vehicles in which a pair of levers transmit a reaction force transversely of the vehicle to counteract tilting moments, thereby holding the vehicle body relatively upright and distributing the weight uniformly on the wheels. The levers are connected to the body at their outer ends, connected to each other at their inner ends, and pivotable on fulcrums supported on the axle housing. An added spring assist for the vehicle suspension system is provided by the resiliency of the levers.

Abstract: A traction device for maximizing traction between the rear wheels of a motor vehicle and a road surface including an elongated telescopically adjustable tubular assembly pivotally mounted between the rear wheel axle and the rear spring. The telescopic assembly has an outer elastomeric cushioning ring disposed between the flanges of two outer sleeves one of which is slidable on and the other of which is fixed to an inner sleeve.

Abstract: A vibration absorber for assembling a vibrating element and a non-vibrating lement has an intermediate plate fixed between two parts of an elastomeric material placed between two plates linked by a tubular cross-piece. The absorber is made in two halves each formed from a rigid tubular fastening provided with an end flange and a ring in elastomeric material surrounding the fastening and having a plurality of projections or ribs on its surface removed from the flange. A brace acts on the fastenings across their tubular parts in order to cause the projections or ribs to engage with both sides of the intermediate plate.
