A suspension damper of the monotube gas charged shock type includes mating piston and rod guide assemblies and mating piston and gas cup assemblies wherein the extension and compression travel of the damper is maximized. The piston includes an annular skirt with a lower rebound cutoff element. The rod guide assembly includes twin spaced apart bushing assemblies providing lateral support to the piston rod, a lower annular leg and an upper rebound cutoff element. When the damper is in a fully extended position, the lower annular leg is received within the upper rebound cutoff element and the upper rebound cutoff element is received within the annular skirt of the piston assembly.

Monotube damper

A gas charged monotube strut carries the accumulator outside the damper's cylinder tube and within the strut mount. A substantially direct flow path is provided between the damper and the accumulator through the damper's piston rod. Air to oil separation is maintained by a gas cup and a low profile of packaging is provided.

Suspension strut assembly

Corrugated coring of the inside of an isolator grommet forms radial fingers which engage the outer surface of a metallic spacer which provides an attachment for the arms of a bracket to upper and lower tie bars so that the isolator will provide a high spring rate between a bladed fan and radiator while allowing the fan package to have more freedom in the radial direction while keeping the clearance between the fan and radiator as close as possible while damping the vibratory energy generated by the fan and motor.

Isolation bracket assembly for engine cooling fan and motor

Pneumatic suspension system for automotive application in which sprung and unsprung masses are supported by variable volume air spring units and incorporating compressor and exhaust valve devices for supplying an exhausting pressurized air from the units to adjust the height between the masses. A Hall effect device effective across a pressure boundary senses the position of a magnet movable within one of the air spring units and reflects relative movement of the sprung and unsprung masses to effect control of the supply and exhaust of air from the units. By axial movement of the Hall device, dead band width can be established to accommodate normal ride motions between sprung and unsprung components. By rotating the Hall device at any axial position, the vehicle bumper height can be selectively increased or decreased.

Vehicle pneumatic suspension system with dead band adjustment

A height sensor is provided in a vehicle leveling system having an air spring including a pressurized chamber connected between sprung and unsprung vehicle masses. In one embodiment magnets located on a pair of followers within the chamber and attached for movement with the unsprung mass produce magnetic fields which pass through the wall of the chamber. A pair of detectors outside the chamber and mounted on the sprung mass for movement therewith detects the magnetic fields and thereby the movement of the followers to determine the relative spacing of the sprung and unsprung masses. In a second embodiment the magnetic devices and detectors are outside of the chamber with a follower internal of the chamber adapted to interrupt the magnetic field therebetween to determine the relative spacing of the sprung and unsprung masses.
