Problems solved by technology

If greater forces are applied to the wheels for braking or accelerating the rail vehicle than can be withstood via the wheel-rail contact according to the force locking that exists, this can lead to slipping, skidding or locking of the wheels dead, this is the undesired state

Embodiment Construction

[0026] In the following text, functionally similar or identical components are provided with reference symbols which are distinguished from one another only by the addition of different lowercase letters.

[0027] figure 1 A first variant of an end piece 20 for a particle spreading device for a rail vehicle is shown. The end piece 20 is connected to the particle guide hose 1 of the particle spreading device. In the present example, the connection takes place via a support sleeve 2 accommodated in the guide hose 1 and an adapter 3 . The end piece 20 comprises a connecting piece 4, which consists of a rigid material, such as metal or plastic. The opening of the connection piece 4 facing the particle guiding hose 1 forms the inlet B of the end piece 20 . A first flexible hose part 6 , which forms the outlet A, is arranged at the opposite other opening of the connection part 4 . Between the inlet B and the outlet A a particle flow chamber with end pieces is formed. The inner ...

Abstract

The invention relates to an end piece (20) for a particle distributor for a railway vehicle, comprising a first hose piece (6) that has a first thermal conductivity, and an outer hose piece (7) that has a second thermal conductivity which is smaller than the first thermal conductivity. The end piece further comprises a heating device that includes at least one electrically operable heating element (5). The outer hose piece (7) at least partially surrounds the first hose piece (6). The at least one heating element (5) is accommodated in the first hose piece (6) and / or is arranged between the first hose piece (6) and the outer hose piece (7) in such a way that the at least one heating element (5) is in direct contact and / or heat transferring contact with the first hose piece (6). The end piece (20) is a flexible end piece. The invention further relates to a particle distributor and a railway vehicle.

Description

technical field [0001] The invention relates to an end piece of a granulate spreading device for a rail vehicle as well as a granulate spreading device for a rail vehicle having such an end piece and a corresponding rail vehicle. Background technique [0002] In rail vehicles, the action of the brakes or drives depends decisively on the non-positive connection between the wheels and the rail, since the drive or braking force is transmitted via the wheels to the rail. In this case, the parameter referred to as the coefficient of adhesion or the force-locking coefficient determines the measure of the braking or driving force that can be transmitted to the rail. If greater forces are applied to the wheels for braking or accelerating the rail vehicle than can be withstood via the wheel-rail contact according to the force locking that exists, this can lead to slipping, skidding or locking of the wheels Death is an undesirable state. The non-positive fit between the wheel and th...
