摘要： A controllable pneumatic apparatus including a pneumatic actuator coupled with a linear-acting brake including a field responsive medium. The pneumatic actuator has a housing with a gas cavity, a first piston slidably disposed in the gas cavity subdividing the gas cavity into first and second gas chambers, and an output member coupled to the first piston. The linear-acting controllable brake includes a medium containing cavity subdivided into a first and second chambers, and a second piston rigidly interconnected with, and longitudinally aligned with, the first piston. A passageway interconnects the first and the second chambers and a field responsive medium (e.g., a magnetic fluid) is contained in the passageway. A field generator produces a field to change a rheology of the medium and cause a braking force to be applied to the output member to control motion thereof. A preferable control method implements motion control based upon the kinetic energy and the braking force in the system.

摘要： A piston assembly is provided for a disc brake assembly to reduce the heat transferred to the hydraulic fluid of the disc brake assembly during braking. The piston assembly preferably includes a piston and a heat insulator designed to be movably coupled to a caliper housing to move a friction member between a release position and a braking position The piston has an internal recess to partially receive the heat insulator. The heat insulator is disposed between the piston and the friction member to reduce heat transfer from the friction member to the piston. Specifically, the piston and the heat insulator are configured to use air spaces to reduce heat transfer from the friction member to the piston.

摘要： A spring having a main gas chamber, a secondary gas chamber and sealing surfaces which, during a portion of the stroke of the piston rod, define a gas tight seal between them to provide two separate gas chambers each providing a force acting on the piston rod in opposed directions to each other to reduce the net force on the piston rod. When the piston rod is near its fully extended position the sealing surfaces provide the gas tight seal and the net force on the piston rod is minimal and in the direction to move the piston rod to its fully extended position. Thus, until the cooperating surfaces are displaced to terminate the gas tight seal, only a slight force is required to initially move the piston rod from its fully extended position. This greatly reduces the impulse or impact force imparted to a press ram upon initial actuation of the fully extended piston rod. A second seal assembly may also be provided which controls the rate at which the piston rod assembly returns to its fully extended position. After the gas tight seal is terminated, the gas spring functions generally as a conventional gas spring with a single gas pressure acting on the piston rod and biasing the piston rod towards its extended position against the force of the ram displacing it.

摘要： A vehicle suspension assembly includes a shock absorber that provides variable damping dependent on the load conditions of the vehicle. A central rod of the shock absorber includes a central bore that is fluidly coupled with air pressure within air springs of the suspension assembly. As the vehicle load increases and the pressure within the air springs increases, a damping adjustment assembly within the shock absorber increases the stiffness or damping of the shock absorber. In one example, a plunger moves within the central bore in the rod between a first position where less damping is provided and a second position where increased damping is achieved. A unique adapter member facilitates using a rod of appropriate size to achieve the desired air pressure conditions within the rod, while at the same time supporting conventional piston and disc valve components and providing enough material strength to withstand the tensile loads experienced under full extension. The adapter also includes a check valve to control fluid flow and provides a hydraulic cushion feature.

摘要： A magnetorheological fluid damper is provided which permits effective control of damping while minimizing assembly size and costs by including a thin-walled insert in a flow gap formed between a flux ring and a piston body. The insert may include a thin-walled tubular insert having a generally smooth cylindrical shape for increasing the shear surface area. Alternatively, a corrugated insert may be provided having corrugations formed by edges extending axially along the insert. The corrugations may be formed in a variety of locations, sizes, shapes and spacings along the axial extent of the insert and the circumference of the insert. The corrugations advantageously effectively align the insert within the flow gap and also function to securely connect the flux ring to the piston body without the use of other devices such as plates thereby reducing the size and cost of the assembly.
