Title: Hydraulic transmission for construction vehicle - with traction speed regulated relative to working speed of attachment
Inventor: HAGEMEIER JOSEF
IPC: E02F5/02
Filed: 1977-02-19
Abstract: The construction vehicle hydraulic transmission is operated in conjunction with the hydraulic servo drive for the working attachments. This ensures that the vehicle is not moved forward at a rate too fast for the attachments to cope with, thus causing strain and damage to the attachments. The output from the servo drive is used to drive a secondary pump linked to the wheels. The system is suitable for ditching attachments and similar equipment in which the inching rate of the vehicle has to be slow enough to ensure that the attachments clear the ground.
