Definitions

  • the invention relates to an apparatus used to replace damaged and unusable road wheels and torsion bars in tracked vehicles.
  • the invention in particular, concerns a road wheel/torsion bar assembly apparatus equipped with a jaw enabling it to lift the road wheel by rotating the spindle and utilizing its teeth to move upwards, and/or allowing the torsion bar to be removed by releasing the suspension arm when the spindle is rotated in the reverse direction after the wheel is removed.
  • road wheels ensure the continuation of a vehicle's forward movement through their rotation.
  • a damaged road wheel can impair or even render the vehicle immobile. For this reason, a damaged wheel must be replaced in the field.
  • torsion bars in operational vehicles are not in a free state but under pretension.
  • the suspension system is created utilizing torsion bars. Replacing a damaged torsion bar is essential as it negatively impacts the vehicle's mobility.
  • the present invention aims to eliminate the disadvantages outlined above and to introduce new benefits to the respective technical field through an apparatus used in tracked vehicles to replace damaged and unusable road wheels and torsion bars.
  • the primary objective of the invention is to facilitate the replacement of road wheels and/or torsion bars without requiring the vehicle to be placed on a support/block or the removal of the track. Additionally, it enables a fast execution of the process in the field.

  • the claw (12) is clamped onto the track (40) links (41).
  • the wheel hub (21) on the suspension arm (31) presses against the jaw (13).
  • the shaft (14) is rotated using a key or pneumatic hand tool. Through the teeth on the shaft (14), the jaw (13) begins to move upward. During this movement, the torsion bar that is attached starts to tension.

Abstract

L'invention concerne un appareil utilisé dans des véhicules chenillés pour remplacer des galets de roulement et des barres de torsion endommagés et inutilisables. En particulier, l'invention concerne un appareil d'assemblage galet de roulement/barre de torsion (10) comprenant une mâchoire (13) qui s'élève et s'accouple au moyeu de roue (21), et ainsi le galet de roulement (20), en étant déplacé vers le haut par l'intermédiaire de la broche (14), faisant tourner les dents sur celui-ci. Ceci permet le processus de remplacement de galet ou, en variante, le retrait de la barre de torsion (31) par rotation de la broche (14) dans la direction inverse, ce qui libère le bras de suspension (31).
