    摘要: An end-of-car coupler includes a hydro-pneumatic cushioning device. The latter has a ported tube separating the hydraulic cylinder chamber from an outer annular chamber containing gas. Each port is fitted with a valve, the obturating member of each valve being a differential area piston. The valves are all closed until subjected to a certain threshold force by movement of the plunger in the cylinder when all those valves between the plunger and the end of the cylinder chamber open to allow liquid flow between the two chambers.

    摘要: A railway buffer capsule comprising a hollow cylindrical plunger slidably mounted in a cylinder. The cylinder is closed at one end. The plunger is closed at its outer end, and in its inner end is formed a fixed area orifice of flow restricting dimensions. A floating piston slides in the bore of the plunger and separates a liquid reservoir from the remainder of the interior of the plunger which comprises a gas containing space. A stepped piston has its larger diameter exposed to pressure in the reservoir and its smaller diameter end adapted to seat and close the orifice and be exposed to compression chamber pressure. The combination of the stepped piston and the orifice is a multiplier valve which multiplies the resistance of the compressed gas to lengthwise compression of the buffer.

    摘要: A clutch actuating system which is particularly suitable for connecting drive to the front wheels of a four-wheel-drive tractor. The system includes an actuating member movable between a first position in which the clutch is disengaged and a second position in which the clutch is engaged. A pair of adjacent reaction members (27,29) encircle the actuating member and have mutually inclined wedging surfaces (30,31) on confronting faces. One (27) of the reaction members is connected with the clutch (25,26) which is of the toothed-dog type. A number of elongated toggle members (33) are connected at one end with the actuating member (32) and extend between the wedging surfaces of the reaction members at their other ends. Movement of the actuating member from its first to its second position causes the toggle members to execute a toggle action and to be forced further between the wedging surfaces (30,31) to separate the reaction members (27,29) to engage the clutch and cause the toggle members to assume a stable position in which the actuating member is held in its second position by the toggle members thus holding the clutch engaged. The teeth (25,26) of the clutch may be angled on co-operating surfaces to provide a separation force which tends to disengage the teeth to facilitate disengagement of the clutch.

    摘要: A buffer comprising a plunger slidable in a ported tube. A metal tubular member circumferentially surrounds that part of the ported tube in which all the flow resisting ports are formed and is the radially inner wall of an annular space filled with compressed gas. The outer wall of an annular space is formed by a tubular membrane. The annular chamber between the ported tube and the metal tubular member is part of a low pressure reservoir of the buffer and communicates via an annular passage in the closed end of the buffer with the remainder of the reservoir which is an annular chamber formed between the tubular membrane and the outer tubular wall of the buffer. The metal tubular member shields the tubular membrane from the damaging effects of jets of liquid forced through the flow resisting ports during compression of the buffer. Heat generated by forcing the liquid through the flow resisting ports is carried by liquid flow from the radially inner annular chamber to the radially outer annular chamber via the annular passage and is dissipated from the radially outer annular chamber through the external tubular wall of the buffer.

    摘要: A lever mechanism (10) suitably, amongst other uses, for use in the control of tractor draft links (22) from a location remote from the tractor operators station.The lever mechanism includes an operating member (40), a support (43) relative to which said operating member is displaceable (Z), a lever (42) pivotally mounted on the support about a pivot axis (44) which is also translationally moveable (X), a first formation (56) on the lever, a second formation (57) on the operating member, and bias means (53) acting to translationally move the lever on its axis (44) away from the second formation (57) to hold the first and second formations (56,57) disengaged when the lever is released. The operating member is displaceable in a given direction (Z) relative to the support (43) by translational movement (X) of the lever (42) on its moveable axis (44) against the bias (53) to bring the first and second formations (56,57) into engagement followed by pivotting (Y) of the lever relative to the support with the first and second formations engaged.When used to control tractor draft links the lever mechanism forms part of the draft link control system and is connected with the remainder of the system via operating member (40).
