Chassis for machine small milling cutter for stripping off road surfaces - has frame support by front and rear wheels which are suspended on front supports having guides at right angles to frame plane

摘要

The chassis comprises a fame (10) supported by front wheels (26,28) and rear wheels (30, 32). The front wheels are so suspended that they are able to follow variations in the transverse slope of the road surface in an opposite direction and by like amounts. The wheel supports (48, 50) the front wheels and are connected to associated guides (52 to 58) which guide them respectively in a plane at right-angles to the frame plane (20) and parallel with the longitudinal axis of the frame. The movable guide parts (52, 54) for the front wheels are positively coupled by a coupling devices for the oppositely directed movement by the same amounts. The central vertical position of the movable guide parts is adjustable. The coupling device comprises two identical working cylinders (60, 62) which have at least one pair of equivalent working chambers which are respectively connected by a coupling line. The working cylinders are double-acting working cylinders and have their equivalent working chambers connected by respective coupling lines.
