Travel unit for mobile machines

Abstract

The invention relates to a mobile unit for mobile machines having extensible support devices comprising a first, continuous rigid support on which travel devices and some of the support devices are arranged and on which a further continuous support or divided support arms, which support the remaining support devices, are outwardly pivotably linked. In accordance with the invention, the first, continuous rigid support is aligned at an angle to the imagined longitudinal axis of the mobile unit and the further continuous support or the divided support arms are aligned with point symmetry to a real or imagined pivot point on the continuous rigid support, with them likewise supporting travel devices.

1 . A mobile unit for mobile machines having extensible support devices comprising a first, continuous rigid support on which travel devices and some of the support devices are arranged and on which a further continuous support, which supports the remaining support devices, is outwardly pivotably linked,
 wherein   the first, continuous rigid support is aligned at an angle to the imagined longitudinal axis of the mobile unit; and the further continuous support is aligned with point symmetry to a real or imagined pivot point on the continuous rigid support, with likewise supporting travel devices.   
   
   
       2 . A mobile unit for mobile machines in accordance with  claim 1 , wherein the first continuous rigid support is connected to the second, continuous rigid support via a rotary joint at the real pivot point. 
   
   
       3 . A mobile unit for mobile machines in accordance with  claim 2 , wherein a main travel device is arranged in a region of an axis at the rotary joint or real pivot point. 
   
   
       4 . A mobile unit for mobile machines in accordance with  claim 3 , wherein support rollers are arranged as the travel devices on the respective supports. 
   
   
       5 . A mobile unit for mobile machines in accordance with  claim 1 , wherein the first continuous rigid support has two supports outwardly pivotable to the side. 
   
   
       6 . A mobile unit for mobile machines in accordance with  claim 1 , comprising actively steered wheel sets as the travel devices. 
   
   
       7 . A mobile unit for mobile machines in accordance with  claim 1 , wherein the further continuous support is outwardly pivotable via drive means such as piston-in-cylinder arrangements, threaded spindles or transmissions. 
   
   
       8 . A mobile unit for mobile machines in accordance with  claim 1 , wherein the further continuous support is fixable in respective position via fixing means such as multi-plate brakes or bolts. 
   
   
       9 . A mobile unit for mobile machines in accordance with  claim 1 , comprising a longitudinal axis bisecting the entire mobile unit in a retracted or closed state, with the first continuous rigid support askew to the longitudinal axis at all times. 
   
   
       10 . A mobile unit for mobile machines in accordance with  claim 9 , wherein the further continuous support is coupled to the first continuous rigid support at a respective pivot point to define a lateral axis perpendicular to the longitudinal axis when fully-pivoted away from the continuous rigid support and is both parallel to and offset from the lateral axis when fully-pivoted away. 
   
   
       12 . A mobile unit for mobile machines in accordance with  claim 10 , wherein the further continuous support extends parallel to the longitudinal axis when fully-retracted. 
   
   
       13 . A mobile unit for mobile machines in accordance with  claim 1 , wherein the further continuous support extends parallel to the longitudinal axis when fully-retracted. 
   
   
       14 . A mobile unit for mobile machines in accordance with  claim 1 , wherein the support devices are retractable and extendable support plates.
