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 metering device is configured for fitting into a sand-spreading system of a rail vehicle. The metering device has a housing block, in which a sand path extends from a sand-feeding funnel into a vertical sand blow-out channel via a sand-mixing channel, which rises at an inclination from a sand-holding space to a sand deflection space. A pushing air tube is provided for producing an air flow that conveys spreading sand. The pushing air tube protrudes into the sand-mixing channel coaxially from the bottom. A nozzle insert is detachable inserted into an inflow channel, which leads into the sand deflection space from above. The nozzle insert is provided for producing an air jet directed downward into the sand blow-out channel. The amount of scattering sand that is discharged can be metered more precisely and the susceptibility of the metering device to wear is improved.

A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

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 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 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.
