摘要： A controllable platform suspension system (20) for treadmills (18) and other platforms and devices therefor which exhibit controllability of the impact condition of the platform, such as a treadmill deck (36). In the treadmill application, user-selectable damping/stiffness is provided to simulate variable track conditions, such as pavement, rubber, grass, gravel, sand, and the like. The controllable suspension system (20) comprises spring mounts (40) or the like or a flexible deck (36) for allowing movement of the deck (36) relative to the frame (22) at a contact location (29) due to impact and a controllable device such as an Electrorheological (ER) device, Electrophoretic (EP) device, Electromechanical Hydraulic (Semi-Active) device, controllable mounting, or a Magnetorheological (MR) device, such as an MR brake (42a, 42a, 42b), MR damper (42d), or MR mount (42c, 42e, 42f) interconnecting between the frame (22) and platform (36) to provide the user-variable impact restraint. Various MR devices are described which exhibit controllability in a first direction (ex. bound) and substantially unrestricted motion in a second direction (ex. rebound).

摘要： A controllable brake (20) including a rotor (28) supported by a shaft (30) which is rotatably supported by bushings (42) received in housing (22). A coil assembly (48) creates a magnetic field within a pole piece (32), which is preferably manufactured from a powdered metal material, which preferably has a density of between about 6.8 and 7.0 gm/cm. A magnetically-soft medium is contained within first and second gaps (86, 88) located between pole piece (32) and rotor (28). In one aspect, a magnetic saturation zone (25) reduces the propensity of magnetizing the shaft (30). In another, the pole halves (24, 26) are received in radially-spaced pole pockets (37) formed in the housing (22) and include an axial bias spring (70) to ensure intimate contact. In another aspect, a lip projection (76) traps fluid (23) between the lip projection (76) and shaft (30) and minimizes fluid exposure to the shaft seal (44). In another aspect, cooling fins (55) or a projection (53) restrains rotation of the housing (22). In another aspect, a spring (46) centers the rotor (28) relative to the housing (22).

摘要： An isolator for use in a hand-held vibrating device for providing optimum vibration isolation by utilizing elastomeric buckling sections which operate in a buckled mode during normal use. The buckled elastomer sections significantly reduce the spring rate within an operating load range thus substantially reducing the vibration transmitted to the user. Six embodiments are shown which utilize buckling sections to enhance vibration isolation along an axial direction of vibration. A first embodiment includes a frustoconical section, while the second employs a W-shaped buckling element. A third embodiment includes use of a tuned fluid inertia which is tuned to substantially coincide with a predominant operating frequency of the vibrating device and produces amplified counter inertial forces to substantially reduce the vibration transmitted to the user, while three other embodiments employ metallic buckling springs. Another embodiment employs a tuned vibration absorber and still another combines a tuned mass with a buckling column. A first embodiment of a front grip isolator that is used with the buckling isolator for reducing the radial mechanical vibration transmitted to the front hand of the user, also utilizing buckling sections, is taught. A second embodiment of the grip isolator has buckling sections with low combined axial stiffness to provide both radial and axial vibration isolation.

摘要： The invention provides a hydropneumatic suspension system which is particularly suitable for lorry cabs of the kind which require to be tilted about a horizontal axis for access to the engine. Such a system normally has the disadvantage that a hydropneumatic unit, incorporating a diaphragm does not provide a firm pivot anchorage for the cab tilting system.The invention overcomes this problem by pivotally attaching one portion of the displacer unit, below the diaphragm, to a downwardly extending formation of the cab and arranging for abutment between the formation and the displacer unit portion above the tilt axis to maintain the displacer unit portions in alignment when the cab is in the ride position.
