Snow-clearing vehicle

Abstract

A snow-clearing vehicle comprises a carrier vehicle and, attached to the front end thereof via a carrying device, a snowplow with at least one plowshare segment mounted to be variable in position in such a way that, upon encountering an obstruction, it executes an evasive movement to take it out of an operating position. In the process, at least one restoring spring exerts resistance in opposition to the evasive movement and returns the plowshare segment to the operating position after the obstruction has been passed. Furthermore, a braking device with electrically adjustable brake characteristic acting parallel to the restoring spring at least over part of the evasive movement and a transducer acting on the braking device via an electrical interface are provided.

1 . A snow-clearing vehicle, comprising:
 a carrier vehicle and,   attached to the front end thereof via a carrying device, a snowplow with at least one plowshare segment mounted to be variable in position in such a way that, upon encountering an obstruction, it executes an evasive movement to take it out of an operating position,   wherein at least one restoring spring exerts resistance in opposition to the evasive movement and returns the plowshare segment to the operating position after the obstruction has been passed,   wherein a braking device with electrically adjustable brake characteristic acting parallel to the restoring spring at least over part of the evasive movement and a transducer acting on the braking device via an electrical interface are provided.   
     
     
         2 . The snow-clearing vehicle of  claim 1 , wherein the transducer comprises an electronic control unit, which in turn is in communication with at least one sensor and which processes measured values already provided thereby. 
     
     
         3 . The snow-clearing vehicle of  claim 2 , wherein a collision sensor is provided, the signal of which is delivered to the electronic control unit. 
     
     
         4 . The snow-clearing of  claim 1 , wherein the transducer comprises a manually operable input unit disposed in the driver's cab of the carrier vehicle. 
     
     
         5 . The snow-clearing vehicle of  claim 1 , wherein the braking device generates a braking force as a function of the dynamic characteristic of the evasive movement. 
     
     
         6 . The snow-clearing vehicle of  claim 1 , wherein the brake is equipped with a magnetorheological shock absorber. 
     
     
         7 . The snow-clearing vehicle of  claim 1 , wherein the braking device comprises a retaining device, the braking effect of which decreases suddenly during the evasive movement from a high release value.
