摘要： RETURN SENSE WHEN THE SPRING DISTENDS UPON REMOVAL OF A KINETIC LOAD.

A SUSPENSION FOR THE BOLSTER OF A RAILROAD CAR IS CHARACTRIZED BY TWO RELATIVELY MOVABLE CHAMBERS, SEPARATED BY AN ELASTOMERIC SLEEVE CONSTITUTING THE MAIN SPRING. THE TWO CHAMBERS COMMUNICATE THROUGH NORMALLY OPEN DAMPING PASSAGES THROUGH WHICH OIL MAY BLEED FROM ONE CHAMBER TO THE OTHER WHEN THE SPRING IS COMPRESSED, AND A ONE-WAY VALVE SYSTEM ALLOWS UNRESTRICTED OIL FLOW IN A

摘要： The invention provides a diaphragm-type hydraulic displacer unit of the kind which includes a piston-like member arranged to move inwardly and outwardly of a cylinder-like member, the annular gap between the piston and cylinder being bridged by a flexible diaphragm and in which during operation the ration between the maximum stroke of which the unit is capable and the maximum effective bore of the diaphragm, occurring in operation, is at least 1.2 : 1, and may be 2 : 1 or more, and in which during all operative conditions the pressure across the unsupported diaphragm loops exceeds 100 pounds per square inch. The invention is concerned with ensuring longevity of the diaphragm in such a unit and provides that the unit shall have the following features in combination: A. THE FLARED FLANKS OF THE PISTON AND THE INNER WALL OF THE CYLINDER SKIRT ARE TAPERED IN OPPOSITE DIRECTIONS SUCH THAT OVER THE MAXIMUM STROKE PERMITTED IN OPERATION, THE EFFECTIVE BORE OF THE DIAPHRAGM INCREASES AS THE PISTON MOVES INWARDLY OF THE CYLINDER AND SUCH THAT THE DIMENSION OF THE EFFECTIVE BORE OF THE DIAPHRAGM, WHEN THE PISTON IS IN ITS INNERMOST POSITION IS BETWEEN 15 PERCENT AND 25 PERCENT GREATER THAN THE DIMENSION OF THE EFFECTIVE BORE OF THE DIAPHRAGM WHEN THE PISTON IS IN THE OUTERMOST POSITION OF ITS PERMITTED STROKE; B. THE PISTON FLANKS AND THE INNER WALL OF THE SKIRT ARE SO CONSTRUCTED THAT THE RATIO BETWEEN THE EFFECTIVE BORE OF THE DIAPHRAGM AND THE LOOP RADIUS OF THE DIAPHRAGM WILL ALWAYS BE GREATER THAN 11 : 1 THROUGHOUT THE PERMITTED STROKE, WITH THE LOOP RADIUS BEING MAINTAINED SUBSTANTIALLY CONSTANT WITHIN 10 PERCENT THROUGHOUT THE PERMITTED STROKE; C. THAT THE DIAPHRAGM IS INITIALLY MOULDED IN THE SHAPE WHICH IT WOULD BE FORCED TO ADOPT WHEN THE PISTON IS ADVANCED TO A POSITION FURTHER INTO THE CYLINDER THAN WOULD BE OCCASIONED DURING ITS NORMAL OPERATION IN THE PERMITTED STROKE; D. THE CORD REINFORCEMENT OF THE DIAPHRAGM CONSISTS OF AT LEAST TWO PLIES HAVING A BIAS ANGLE OF BETWEEN 30* AND 50* INCLUSIVE; E. THE THICKNESS OF THE DIAPHRAGM IS SUCH THAT THE RATIO BETWEEN THE LOOP RADIUS OF THE DIAPHRAGM AND THE THICKNESS OF THE DIAPHRAGM IS ALWAYS GREATER THAN 2 : 1 THROUGHOUT THE PERMITTED STROKE.

摘要： A railway vehicle having three pairs of wheels of which the axles are supported by axle boxes, and a suspension for the wheels comprising, for the axle box of each wheel of the center pair of wheels, a pair of oppositely extending equalizing beams, each beam being connected to the central axle box by means of a resilient pad located between two abutment faces associated respectively with the beam and the central axle box, the beams extending in the longitudinal direction of the vehicle and the ends of the beams remote from the central axle box being connected respectively to the adjacent one of the axle boxes of the two other wheels on the same side of the vehicle, and rubber springs supporting the vertical load of the suspended part of the vehicle from the equalizing beams and acting to transmit the longitudinal traction and braking forces between the wheels and the suspended part of the vehicle, the rubber springs being positioned so as to distribute the vertical load of the suspended part of the vehicle in a required proportion between the wheels.
