摘要:
A rail vehicle, such as a locomotive, has at least one undercarriage with one or more wheel sets and an undercarriage frame. A vehicle body, resiliently supported on the undercarriage, has a vertical pivot pin passing through the undercarriage frame for traction linking the vehicle body. A limiting stop is connected to the pivot pin for limiting the vertical motion of the vehicle body relative to the undercarriage frame. The pivot pin has a horizontal through-hole in a downwardly protruding pin segment for supporting the limiting stop. Contact protrusions of the limiting stop protrude from the through-hole on both sides of the pivot pin. In the event of maximum vertical motion, the limiting stop contacts the undercarriage frame from below by way of the contact protrusions. The entrainment of the undercarriage is thus effected with great safety when the rail vehicle is lifted.

End members (202, 204) dimensioned for securement to an associated flexible wall (206) of a rail spring assembly (200) can include an end member body formed from a polymeric material and can have a longitudinal axis (AX). The end member body can include an end wall (232) that extends transverse to the longitudinal axis. An outer side wall (234) can extend longitudinally from along the end wall. An outer peripheral wall (264) can extend from along the outer side wall and can be dimensioned to abuttingly engage the associated flexible wall. A plurality of support walls (272) can extend between and operatively interconnect the outer side wall and the outer peripheral wall and thereby buttress at least the outer peripheral wall against loads applied by the associated flexible wall. Gas spring assemblies including one or more of such end members and suspension systems for rail vehicles including one or more of such gas spring assemblies are also included.

An air spring includes an upper surface plate, a lower surface plate, and a diaphragm connecting the upper surface plate and the lower surface plate. The diaphragm has an annular shape having an opening on an inner circumferential side. In the diaphragm, an upper surface plate contact portion, which is a region defining the opening and being in contact with the upper surface plate, includes a deformed portion elastically deformed to protrude toward the lower surface plate side by contact with a support plate. The deformed portion is in contact with a sliding member located on the lower surface plate side when viewed from the deformed portion.

A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.

Leveling railway vehicles, leveling secondary suspension systems, lift-systems for suspension systems, and other related systems and methods are shown and described. In one example, a railway vehicle includes a superstructure, a bogey, and a leveling secondary suspension system. The leveling suspension system includes at least one spring positioned between the superstructure and the bogey, and a secondary suspension-mounting lift system (SMLS) interfaced with coil spring. The SMLS includes a spring-mount (SM) and a piston assembly. In operation, pressurized hydraulic fluid acts on the piston and lifts the superstructure, thereby allowing the superstructure's access to be raised to a desired height, e.g. a platform height.

Disclosed is a spring assembly for level controlled support of a wagon body on a running gear of a vehicle, in particular of a railway vehicle, including a spring device and an actuator device, wherein the spring device takes up a first installation space, the actuator device takes up a second installation space, the spring device and the actuator device are connected to each other in a direction of action in a kinematically serial arrangement, and the actuator device is designed for at least partially compensating for a change in length of the spring device in the direction of action by a displacement at an actuator component in the direction of action, and wherein the first installation space and the second installation space overlap each other in the direction of action in an overlapping region. Also disclosed is a vehicle having such a spring assembly.

An air spring for railroad cars includes an air spring part formed by an upper support on a vehicle body side, an intermediate support arranged therebelow, and a diaphragm made of rubber and extending between the upper support and the intermediate support; and an elastic mechanism b formed by a rubber mass 5 interposed between the intermediate support and a lower support 4 on a bogie side arranged therebelow. The rubber mass 5 has an end in contact with the lower support 4 formed as an enlarged end 5A increasing in diameter as approaching the lower support 4 in a vertical direction. An outer circumferential portion of this enlarged end is fitted in and bonded to an annular groove 12 formed in the lower support 4, and the annular groove 12 has an annular bottom 12A inclined to decrease in height radially outwards to have an annular tapered bottom 12a.

A wheel truck for a railroad car, including: a front wheel pair assembly and a rear wheel pair assembly; two side frame assemblies, each side frame assembly including a square box and journal-box guides; two spring suspension devices; and a bolster assembly including two ends disposed on the two spring suspension devices, respectively. The bolster assembly includes a pilot hole in the center and two mounting holes on the two ends, the pilot hole is rotationally matched with a cylindrical upper center plate of a car body for transmitting vertical and horizontal forces from the car body, and the two mounting holes are disposed above the two spring suspension devices, respectively. Each mounting hole receives a lower side bearing, and the lower side bearing is matched with a corresponding upper side bearing disposed on each side of the car body for transmitting the vertical load from the car body.

A bogie for a locomotive comprising a bogie frame and at least one wheel set including two wheels, a wheel set gear, a wheel set shaft and a wheel set gear housing. A push/pull rod acts on one side of the bogie frame and on the other side of locomotive frame and transfers forces between the two. The gear housing of the wheel set exhibits a recess for the feeding through of the push/pull rod, the recess being bordered by walls which are integral with the remaining housing walls.
