Abstract: An inner pressure pad is positioned on support members adjacent to the disk and generally parallel to the disk. An outer pressure pad is positioned on the support members with the disk interposed in between the inner pressure pad and the outer pressure pad, and the outer pressure pad is generally parallel to the disk. Springs are inserted on the support members and interposed in between the inner pressure pad and the outer pressure pad to urge the outer pressure pad away from the disk. A lever is pivotally mounted on the support members at a distance away from the outer pressure pad, and normally extends generally parallel to the outer pressure pad. Adjusting means are secured to the lever with one end extending to normally contact the outer pressure pad. A frame member is secured to the support members to partially enclose the lever and the disk. The frame member has a fulcrum formed thereon protruding from the frame member to contact the lever on the side opposite from the disk.

Abstract: A fluid-filled resilient bushing including an annular resilient member interposed between inner and outer sleeves, and a stopper block having a pair of stopper portions disposed in respective fluid chambers defined by the outer sleeve and the resilient member. The chambers are located opposite to each other in a first direction in which the bushing receives vibrations. The two chambers, filled with an incompressible fluid, communicate with each other through an orifice. The stopper portions extend from the inner sleeve toward the outer sleeve. Each stopper portion has a radial end face having an edge which is spaced apart from a periphery of the corresponding fluid chamber in a second direction perpendicular to the first direction, so as to define an annular spacing. A damping member is provided on the radial end face of at least one of the stopper portions.

Abstract: A fluid-filled resilient support structure including a first annular resilient member disposed radially outwardly of an inner sleeve, a pair of annular closure members closing opposite ends of an annular space between the inner sleeve and the first resilient member, a cylindrical member fitted on an intermediate portion of the inner sleeve, an orifice member spaced radially outwardly from the cylindrical member, a second annular resilient member between the orifice member and the cylindrical member, and an outer sleeve fitted on the outer surface of the orifice member. The orifice member has a radially outer portion sandwiched between upper and lower portions of the first resilient member in the axial direction. The orifice and cylindrical members and the second resilient member axially divide the annular space into two fluid chambers which are closed at the opposite axial ends of the first resilient member by the closure members. The orifice member has a circumferential groove formed in its outer surface.

Abstract: The mount preferably includes a decoupler assembly that causes different degrees of damping of relatively large magnitude excitation forces that result in mount compression versus mount extension, and that causes no or only minimal damping of excitation forces of relatively small amplitude. In a preferred embodiment the mount includes a generally cylindrical double-walled housing having a central portion containing at least part of a first variable volume chamber containing hydraulic fluid, and having an outer portion containing a second variable volume chamber containing gaseous fluid. The second chamber is of annular shape and encircles at least part of the first chamber. A rolling diaphragm defining a boundary of at least one of the chambers is formed of elastomeric material having a layer of reinforcing material preferably disposed at an offset location therein.

Abstract: A switching valve device in an air suspension system for such vehicles as automobiles, wherein a plurality of primary air chambers are provided above a shock absorber, which are connected or disconnected with each other to adjust the air spring constant for such vehicles as automobiles rotary valve is provided in the course of the path connecting the respective primary air chambers, and a decompression intercommunicating cushioning air chamber is formed between the rotary valve and a flow restriction stopper holding the rotary valve in place, such that the communication of the cushioning air chamber with one primary air chamber is opened and closed or controlled through the rotary valve, on the one hand, and such that its communication with another primary air chamber is through the flow restriction stopper, on the other hand, whereby a swish sound is prevented by the decompressing action of the cushioning air chamber.

Abstract: A brake carrier (12) straddling the edge of a brake disc (10) guides two brake pads (24,26) disposed at one side each of the brake disc (10). The brake comprises an actuator (22) having an actuating axis (B) defining a radial center plane (C) together with the axis (A) of the brake disc. Two guide bolts (18,20) are arranged at the brake carrier (12) at least approximately parallel to the axis (A) of the brake disc at that side of the center plane (C) which is the trailing side, based on the direction of rotation (D) of the brake disc (10) during forward travelling. A caliper (16) is guided for displacement at the brake carrier (12) by means of the guide bolts (18,20). The actuator (22) acts directly on the one brake pad (24) and by way of the caliper (16) on the other brake pad (26). The brake carrier (12) has guide faces (34,36) for the brake pads (24,26) effective upon braking during forward travelling at the trailing side only.

Abstract: A hydraulic shock damper comprises a hydraulic cylinder and a piston having apertures and dividing the cylinder in upper and lower chambers. Through a flow channel the upper chamber of the cylinder is connected to a dashpot accomodating a partition element. The space being enclosed between the partition element and the closed end of the dashpot is filled with a pressurized fluid. Spaced around the said cylinder a second cylinder is provided, an open connection between the lower chamber of the first mentioned cylinder and the space between both cylinders being provided. Two branch lines are connected to the flow channel and emerge into a single line which in turn emerges into said space. In each branch line an externally controllable closure means and a non-return valve are arranged. Both non-return valves open in opposing fluid flow directions.

Abstract: A fluid-filled elastic mounting structure includes an elastic member, hat-shaped outer and inner partition members superimposed on each other with their cup-shaped portions open on the same side and cooperating with the elastic member to define an operating chamber, and a flexible closure member cooperating with the outer and inner partition members to define an equilibrium chamber. The operating and equilibrium chambers are filled with a fluid and communicate with each other through an annular space which is defined by the cylindrical walls of the outer and inner partition members. The outer and inner partition members cooperate to define a flat space between their bottom walls.

Abstract: An automatic adjustment apparatus for the brake lever of a vehicle brake with a worm drive, an adjustment mechanism and a one-way coupling. The automatic adjustment of the brake lever on the brake shaft takes place by means of a one-way coupling. When there is a manual adjustment of the brake lever in the direction of the release of the brake jaws, the one-way coupling can be mechanically disengaged.

Abstract: A hydrodynamic retarder has a centrally disposed chamber which is filled with hydraulic fluid and subjected to centrifugal forces. A valve mechanism, responsive to the operator, is opened by a control valve system when vehicle retarding action is requested to permit rapid filling of the retarder vane space from the centrally disposed chamber. The valve mechanism is also closed by the control valve system after a predetermined time. This accommodates fast filling of the retarder but does not permit air ingestion by the retarder. A passage, in the stationary housing portion of the retarder, is opened to the transmission pump circuit during retarding action to maintain the retarder pressure and fluid circulation for cooling. The central chamber has an air control valve to admit air to the chamber as the chamber empties of hydraulic fluid and to permit air exhaust therefrom when the chamber is refilled.

Abstract: An auxiliary manual and physically controlled fluid pressure handling apparatus for vehicular pneumatic systems induced into the braking system to become a tool to aid the operator in providing rapid OFF-and-ON impulse or conventional braking, the selection of which is dependent upon the amount of force applied by the operator against the brake pedal, which also controls the frequency of intermittent application of the brakes by the apparatus.
