<p>The machine adjacent wheels (2a,2b) support the frame (1) and the suspensions (1a,1b) elevate and lower each wheel w.r.t. the frame. Each suspension comprises a lower and an upper suspension arms (6a,6b) and (7a,7b). The lower suspension arms are mounted by means of first joints (10a,10b) on the frame and by means of second joints (8a,8b) on the mounting arms (5a,5b). The upper suspension arms are fixed by means of third joints (11a,11b) on the frame and by means of fourth joints (9a,9b) to the mounting arms. The first and/or third joints are located on the center line, can swivel about axis (R1,R2) and are arranged one after the other in the longitudinal direction of the frame. The wheels are lifted or lowered by cylinder actuator (12a,12b).</p> |
