Sand Spreading Device in Rail-Borne Vehicles, In Particular High-Speed Vehicles

Abstract

A sand spreading device in rail-borne high-speed vehicles in which a metering device and a conveying device are provided. For preventing a lateral discharge of the conveyed sand, both devices do form one unit, yet are separately controllable. When using a bucket wheel (Z) controlled by a vehicle speed indicator (FT), it will be possible to achieve an exact, infinitely variable amount of sand, or conveyance, respectively.

1 . A sand spreading device in rail-borne vehicles, in particular in high-speed vehicles, using a metering device and a conveying device, characterised in that both devices form one unit, yet are separately controllable. 
   
   
       2 . The sand spreading device according to  claim 1 , characterised in that the one device is a bucket wheel. 
   
   
       3 . The sand spreading device according to  claim 2 , characterised in that the bucket-wheel metering is controlled by a vehicle speed indicator.
