Between the frame (1) and a wheel axle provided with a nave, for each wheel on opposite sides of it is a pair of elastically pliable shock absorbers (10, 10'), which allow the frame rear part to spring in relation to the wheels. A fork (11) inclined forwards and upwards is connected with the corresponding shaft (3, 3') at a point at a distance in front of the cross beam (2). A joint arrangement (21) permits pivoting of the fork in relation to the shaft. The individual shock absorbers incorporate partly a cylinder part (13) with unalterable length, partly a shorter bellows part (14) with unalterable length. The cylinder part with a lower end is connected to the wheel axle, whilst the bellows part with the upper end is connected with the cross beam. The cylinder part of the shock absorber is rigidly connected at its lower end with a console on which the wheel axle is fitted. |
