Power train for an agricultural vehicle comprises a tube with two deformations at two opposite ends of the same diameter and a coupling with a groove which can receive the tube deformations

摘要

Power train comprises a tube (1) of constant thickness wall, which has a nearly circular profile with two deformations (3) at two opposite ends of the same diameter. A coupling (4) comprises a bore (7) of same profile as the tube and a groove (9) which can receive the tube deformations. Independent claims are also included for a tool to assemble the tube and the coupling and a method to assemble them.
