Embodiment Construction

[0040] Figures 1 to 4 A first embodiment of a wheel suspension according to the invention is shown. compared to Figures 1 to 4 An example of the structure with a slight modification in the Image 6 and shown in 7 and 8. Identical components are provided with the same reference symbols in the figures.

[0041] The wheel suspension is formed as two independent single-wheel suspensions in the form of swing-arm axles (Schwingenachsen). Each wheel side 100 , 101 is supported elastically via a pivot arm 12 on a vehicle frame 102 about a horizontal pivot axis oriented transversely to the direction of travel. The wheel sides 100 , 101 are supported via steering knuckles 23 , 24 rotatably about vertical axes of rotation on the swing arm tip. The actuation of the swivel bearings on the wheel sides 100, 101 takes place by means of tie rod arms 20, 21 which are articulatedly connected to the individual tie rods 3, 3'. Both tie rods 3 , 3 ′ are hingedly mounted on a central reversi...

Abstract

The invention relates to an axle wheel suspension for a travelling crane. The suspension is provided with two wheels, and the wheel can be suspended on a chassis through an independent single-wheel suspension. The single-wheel suspension comprises at least one swinging arm serving as the wheel supporting part. The suspension comprises a steering lever.

Description

technical field [0001] The invention relates to a wheel suspension for an axle of a mobile crane, said wheel suspension having two wheels, which can be suspended via an independent single-wheel suspension or be suspended on a mobile crane on the chassis and the single-wheel suspension includes at least one swing arm as a wheel carrier. Background technique [0002] Descriptions of conventional crane axles are available from figure 1 obtained from the description. The crane axle is articulated via two longitudinal links A below and via two inclined links B above to the chassis of the mobile crane. The illustrated axle is driven via a drive C. The entire axle structure is a continuous member connecting the two wheels to each other. When the wheels are pressed in elastically, the entire axle structure including the drive C is moved. It must therefore be ensured in the design of the components that the vehicle frame as well as the axle components allow this movement and pro...
