A system and method herein relate to vehicle control by adjusting a torque distribution of the vehicle. The system includes a first motor configured to provide a torque to a first wheel, and a delivery system configured to controllably apply a traction control compound to a route on which the first wheel is configured to travel. The system also includes a controller circuit having one or more processors. The controller circuit is configured to control the delivery system to apply the traction control compound to the route based on a monitored temperature of the first motor.

A grit dispensing device for rail vehicles, having a grit tank; a compressed air source connected to a dispensing line for the grit via a pressure line and a nozzle; an intake channel via which grit can be conveyed from the grit tank into the dispensing line; a bypass which leads from the pressure line to a point in the dispensing line downstream of the mouth of the intake channel so as to bypass the nozzle and the passage cross-section of which can be controlled by a valve; and an electronic control device for the valve, the control device being designed to open and close the valve in intervals with a frequency adapted to the length of the dispensing line in such a way that grit charges which are ejected in the individual open periods of the valve consolidate in the dispensing line to form a steady grit flow.

A device for scattering grit in front of the wheels of a vehicle comprises a housing having a feed inlet for the grit, an outlet for the grit and a substantially cylindrical recess for receiving a brush roll which is rotatably mounted and driven about a substantially horizontal axis of rotation for the metered delivery of the grit from the feed inlet to the outlet. At least one wedge is arranged in the region of the feed inlet for the grit, in front of the brush roll and tangentially and displaceably with respect to the brush roll so that the size of the feed inlet can be adjusted.

A combined track conditioning unit includes a dispensing apparatus with an outflow opening integrated in the front region of the dispensing apparatus which is suitable for applying a gaseous drying medium to a rail. A gritting material outlet unit which is integrated in the rear region of the dispensing apparatus and is suitable for applying a gritting agent to the rail also forms part of the dispensing apparatus. A rail vehicle is also provided. Additionally, a method for increasing a coefficient of friction between a rail and a wheel of a rail vehicle with the aid of a track conditioning unit is provided.

The invention relates to a screening element for screening and transporting grit material, for applying to a sanding device of a sanding apparatus for a vehicle. The screening element includes a plate element provided with a shaft-coupling mechanism, at least one through-opening, and at least one lug. The shaft-coupling mechanism is designed to couple the screening element to a shaft device of a rotary feeder of the sanding device. The through-opening is arranged in the plate element and is designed to guide grit material through the plate element. The lug extends transversely in relation to a main surface of the plate element, away from the plate element.

A grit dispensing device for rail vehicles, having a grit tank; a compressed air source connected to a dispensing line for the grit via a pressure line and a nozzle; an intake channel via which grit can be conveyed from the grit tank into the dispensing line; a bypass which leads from the pressure line to a point in the dispensing line downstream of the mouth of the intake channel so as to bypass the nozzle and the passage cross-section of which can be controlled by a valve; and an electronic control device for the valve, the control device being designed to open and close the valve in intervals with a frequency adapted to the length of the dispensing line in such a way that grit charges which are ejected in the individual open periods of the valve consolidate in the dispensing line to form a steady grit flow.

Polymer compositions having improved electromagnetic (EMI) shielding properties under high temperature are disclosed. The polymer compositions comprise a thermoplastic polymer, stainless steel fiber, and optionally one or more of glass fiber, a conductive filler, a second polymer, and other additives. The disclosed compositions maintain heat resistance and other mechanical properties under high temperatures.

A device for spreading granulate, particularly for spreading sand into the gap between a rail and a wheel of a rail vehicle, includes a housing, at least one inlet for the granulate and at least one outlet for the granulate, an axially movable metering piston and a compressed air connection, which leads into a pressure chamber and serves for actuating the metering piston by compressed air to meter the granulate. At least one bore is provided in the metering piston. To create a device which is of particularly simple and compact construction, a conveying air chamber separated from the pressure chamber and has a compressed air connection is provided, and at least one bore in the metering piston connects the conveying air chamber to the at least one outlet for the granulate, such that granulate can be conveyed to the at least one outlet by compressed air independently of the metering process.
