摘要:
An equalizer for a suspension system for a trailer is configured to absorb or dampen the harsh shocks or vibrations coming off of the leaf springs proximate to a center frame hangar, thus allowing for a “softer” ride. The equalizer utilizes two independent equalizer arm assemblies which are each rotatably secured within the equalizer. Each equalizer arm assembly is operatively associated with one of the front or rear leaf springs such that upon upward movement of either the front or rear leaf spring, the associated equalizer arm assembly is forced to rotate within the equalizer and to deform a shock absorber provided within the equalizer. The shock absorber, upon the deformation thereof, absorbs the harsh shocks or vibrations which would otherwise normally be transferred from the leaf springs, to the equalizer, and thus to the frame of the trailer.

A suspension system for wheeled vehicles, particularly trailers, that is mounted underneath the vehicle frame and forward of the axle (in case of a single axle suspension) and both forward and rearward of axles (in case of a tandem axle suspension). The suspension system at each side of the vehicle frame comprises a hanger, a control arm and an elastomer spring. The hanger has a support bracket and a hanger channel and is the frame bracket connecting the suspension to the vehicle frame. The elastomer spring biases the control arm and the hanger and therefore isolates the vibration of the suspended portion of the vehicle (the sprung mass) from that of the axle(s) and wheels (the unsprung mass).

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.

A trunnion air ride suspension system. In one example, a trunnion suspension system includes a trunnion beam pivotably mounted to a hanger bracket, and an axle pivotably mounted to the trunnion beam. A brake actuator is secured to the axle and pivotably mounted to the trunnion beam, so that the brake actuator pivots with the axle relative to the trunnion beam. In another example, a trunnion suspension system includes a trunnion beam pivotably mounted to a hanger bracket, the trunnion beam having a longitudinally extending cylindrical portion positioned between two generally vertical plate portions. An axle is pivotably mounted to the cylindrical portion by a bushed connection, the bushed connection being retained longitudinally between the plate portions.

Method and arrangement for providing a bearing arrangement for mounting the spring suspension for a leaf-spring-supported bogie on a vehicle. The arrangement includes a bracket, a leaf-spring support and two bearing elements. The bearing elements have a number of parallel, conical, tubular supporting elements and at least one conical, tubular liner.

A straight portion of a vehicle stabilizing bar is fitted with a supporting device including an antifriction sleeve made of low-friction polymeric material and angularly integral with the straight portion of the bar; an annular pad made of elastomeric material and surrounding the antifriction sleeve; and a connecting member for connecting the bar to a vehicle supporting structure, and which is made in one piece from substantially rigid polymeric material, and has a substantially cylindrical through cavity for housing the annular pad; the annular pad clicks axially onto the connecting member and the antifriction sleeve, and is made angularly integral with the connecting member by means of respective longitudinal projections which engage corresponding grooves formed on an inner lateral surface of the cavity of the connecting member, whereas the antifriction sleeve and the annular pad are connected to each other in frictionally rotating manner.

A control circuit is provided for controlling the operation of the solenoid of an air powered actuator which is utilized for retracting the locking pins of a slider used for the adjustment of the suspension of a vehicle longitudinally with respect to the body of the vehicle. The control circuit is operatively connected to the trailer marker light circuit, the service brake light circuit and must be actuated a predetermined number of times within a predetermined length of time, after the service brake light circuit has been actuated for a predetermined length of time, to allow the air powered actuator to be actuated.

A vehicle includes at least one pair of wheels and a respective wheel support arm associated with each wheel for supporting the wheel for rotation, one end of each arm being pivotally coupled to the vehicle. A respective suspension component is secured to each arm and a mounting on the vehicle. A respective support strut has one end secured to the distal end of the suspension component. A respective guide member receives the one end of the strut and the distal end for movement therealong when the vehicle is moved between a travelling position and a loading position.
