Gear linkage for tipping lorry cab - has fixed pivot coaxial to tipping axis for constant setting

摘要

The tipping cab (1) is fitted with a gear selector lever (2) on the floor and linked to the gear box (8). In this a first selector shaft (4) transmits the axial and rotational movements to a kinematic joint (6) whose main axis coincides with the tipping axis. A second shaft (7) links the kinematic joint to the gear box. The gear lever position remains in its setting during the tipping procedure, while the selected gear, or neutral, remains set in the gear box. The system allows relative vibrational movement of the cab on the chassis without affecting the gear setting.
