Exhaust gas suction device for vehicles on running-in and checking sectors of production line, with friction drive on each suction trolley acting on drive belt of endless belt drive

摘要

The exhaust gas suction device has suction trolleys driven in the same direction as the production line by an endless belt drive, each with a suction arm for connecting to the vehicle exhaust. Each suction trolley (2) has a friction drive (8) to act on the drive belt of the endless belt transmission (9), possibly including a spring-loaded counter-roller.
