A mobile earth working machine includes a machine frame; a working apparatus; a functional apparatus connected to the machine frame pivotably; and a pivot joint between the machine frame and the functional apparatus, having a frame-associated joint element and an apparatus-associated joint element. A mechanical coupling includes a frame-side coupling configuration and an apparatus-side counterpart coupling configuration.

A road milling machine includes a machine frame, front wheels or tracks, rear wheels or tracks, and a milling drum supported from the machine frame between the rear wheels or tracks. The front wheels or tracks are mounted on pivoting columns. Steering levers are attached to the pivoting columns. A steering tie rod includes a connecting part and a projecting arm. The connecting part is connected to the steering levers. A steering cylinder is connected to a free end of the projecting arm.

Road milling machine for working road or ground surfaces

A road milling machine with a machine frame supported by a chassis with one front axle and one rear axle with wheels or crawler tracks, with a milling drum mounted at the machine frame to rotate between the rear wheels, where said milling drum ends nearly flush with a zero-clearance side, it is provided that the wheels or crawler tracks of the front axle as seen in the direction of travel are arranged offset from one another in such a fashion that one of the front wheels or tracks is arranged in front of the other front wheel or crawler track as seen in the direction of travel.

Road milling machine for working road or ground surfaces, as well as method for steering a road milling machine

A road milling machine has a driver's cab equipped with a floor plate and a steering gear mounted on the chassis of the road milling machine. The steering gear includes a console, on which a steering wheel is positioned. One end the console is fastened laterally to the chassis, while the other end of the console is not attached to anything. The console extends over the floor plate, forming an opening between the floor plate and the console on a side. Since this opening is below the console, it is possible for the operator to observe the road surface without having to lean to the side, as is necessary with conventional road milling machines, in which the side of the chassis on which the console is positioned blocks the view.
