摘要:
The bogie comprises an axle (14) rotatably mounted on a fixed underframe, and measurement apparatus for measuring a physical magnitude related to rotation of the axle (14). The measurement apparatus (34) comprises a metal disk (36) secured to the axle (14) and provided with at least one mark-forming perforation (40), and a fixed detection assembly (50) for detecting the mark, which assembly comprises at least one inductive proximity detector (52). Preferably, the disk (26) is fixed to a collector ring (26) of a current return assembly (24) for transferring the current coming from a motor of the bogie to the axle (14).
摘要:
The invention relates to a lightweight grounding contact for the transfer of currents between fixed vehicle elements of a rail vehicle and its rotating wheel axle, consisting of a plurality of contact elements (12), acted upon by a pressure in the direction toward the wheel axle, which element rests on a contact surface which originates at the wheel axle and is made of a carbon material. To achieve an always flat resting of the contact element on the contact surface, at least one contact element (12) is acted upon by pressure with a device (22) filled with a fluid (20).
摘要:
A truck or double bogie having forward and rear elemental bogies (1, 2). The vehicle body is carried at the middle by a spanner bolster or two longitudinal coupling beams (8, 9) which are supported, at each end and on each elemental bogie, on the ends of a transverse swingle bar (12, 13), resilient blocks (15) being inserted between the swingle bar and the bolsters (3, 4) of the elemental bogie. The buffer and coupling bodies (34) are arranged at the end of a guide shaft (32) which is freely articulated on a vertical central pivot (30) rigidly fixed to the vehicle body and on the vertical pivot (5) of the forward elemental bogie (1). The device is intended for use with bogies for railroad vehicles intended to run on poor quality track.
摘要:
A railroad car bearing adapter assembly configured to be employed in combination with a high warp restraint truck (with or without an auxiliary or original warp restraint system), and including a low profile thickness and relatively longitudinally narrow roller bearing adapter, a low profile adapter shear pad with a shear stiffness in a range of 85,000 lbs/in to 125,000 lbs/inch, and side wear pad that in combination total clearance in a range of 0.09 inches to 0.36 inches between the side frame thrust lugs and the adapter with the side wear pads. This overall combination reduces wheel wear and damage, reduces fuel consumption, reduces the need for railroad track repair, improves high speed stability and curving performance for both empty cars and loaded cars, provides more truck stability under a loaded car in shallow curves and while encountering certain perturbations, and provides optimum curving performance that enables the axles to better align with curves of relatively high degrees.
摘要:
An elastomeric pad is provided for use in a railway car truck that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of an axle bearing assembly. An elastomeric pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Contact buttons extend from the top surface and bottom surface of the elastomeric pad and are received in openings in the elastomeric pad. A conductor provides an electrical connection between the contact buttons.

A conductor provides electrical connection passing through a rubber cushioned rail vehicle wheel having rubber elements in between a central metal wheel portion and an outer flanged metal wheel tire. Thus, a length of wire has a central conductor connection tag attached to the central wheel portion with U-shaped spring clips at each end straddling over and electrically connecting with an internal mating ridge on the tire extending between two spaced rubber elements separating the central portion and tire.

摘要:
A rail vehicle of the type comprising including at least one equipped axle which is provided with a transmission shaft which is movable in terms of rotation and which is fixedly joined in terms of rotation to two wheels, each of which is provided with a tire, the device including an electric current supply source, the source supplying a friction assembly with electric current. The friction assembly is alone and is electrically connected to a cable assembly which electrically connects the tires of the two wheels, the cable assembly including a cable portion which extends inside the transmission shaft between the two wheels.
