A vehicle fluid spring system is adapted to absorb road shock imparted onto at least one road wheel of a vehicle. The vehicle fluid spring system includes a fluid spring and a variable volume unit. The fluid spring includes a fluid chamber adapted to change in volume. The variable volume unit including a rigid piston cylinder, a piston, a fluid cavity, and an actuator. The piston is adapted to reciprocate within, and is in sliding contact with, the rigid piston cylinder. The fluid cavity is defined by the piston cylinder and the piston. The actuator is adapted to drive the piston changing a volume of the fluid cavity. The fluid cavity is in fluid communication with the fluid chamber.

Continuously variable rate fluid spring system for a vehicle, and method of operation

A suspension component achieves progressive resistance via a secondary bleed valve, which functions as a support for the primary compression valve at higher displacements, in conjunction with a secondary nonlinear spring element configured to alter the force on the piston at high displacements.

Methods and apparatus for a suspension system with progressive resistance

The present invention provides a clutch connected between a robot or like and an attached end of arm tooling device (EOAT). The clutch includes two plates having a fixed relationship with one another. Excessive loading on the EOAT beyond predetermined amounts causes the plates to separate from one another. Any deformation in the fixed position of the plates with respect to one another will cause an instantaneous diminishing of a load transmitted between the two plates.

Clutch for robot or like

Tool changing apparatus for a multi-axis manipulator for selectively receiving and holding one of at least two different work tools. Each of the work tools is mounted on an upstanding table and is provided with a substantially vertical plate and a substantially horizontal plate. A support assembly is provided on the manipulator that is adapted to be locked to the vertical plate on one of the work tools for performing a programmed work cycle after which the work tool is returned and deposited on the upstanding table under program control and the manipulator is then locked to the vertical plate of the other work tool for performing additional operations.
