Embodiment Construction

[0030] FIG. 1 shows a super heavy mining vehicle 1 . In this case the mining vehicle 1 is a transport vehicle for transporting broken rock, rock material or loose soil from a loading site to an unloading site, for example in a mine, quarry or at an excavation site. In addition to transport vehicles, the invention may also be applied to other heavy mining vehicles. The mining vehicle 1 may comprise a frame 2 , a cab 3 , an engine unit 4 and a loading platform 5 . If the mining vehicle 1 is not a transport vehicle, it may be provided with some other implements such as a bucket. The mining vehicle 1 may have multiple wheels, at least some of which are steerable and additionally at least some of which provide traction. The mining vehicle 1 may have two or more steerable front wheels 6, the steering of which enables the vehicle to steer. Each front wheel 6 can be mounted on the frame 2 by a separate suspension 7 so that the front wheel 6 can move vertically according to the irre...

Abstract

The invention relates to an independent suspension for a steerable wheel of a mining vehicle and to a suspension unit. The wheel (6) of the mining vehicle (1) is mounted to a frame (2) via the suspension unit (7) alone. The suspension unit comprises an outer tube (15) attached to the frame and an inner tube (14) arranged partly inside the outer tube, the hub (16) of the wheel being attached to the lower part of the inner tube. The inner tube may move in a longitudinal direction as required by suspension movements and, further, the inner tube may be rotated about its longitudinal axis to steer the wheel. The suspension unit is further provided with hydropneumatic members for producing suspension movement and dampening.

Description

technical field [0001] The invention relates to an independent suspension system for steerable wheels of a mining vehicle, comprising: at least one hub on which at least one wheel can be mounted; A device mounted on the frame of a mining vehicle; at least one steering arm for transmitting steering forces to a wheel hub; and a longitudinally and substantially vertically arranged suspension comprising an inner tube and an outer tube, the inner tube being positioned at the partially disposed within the outer tube at the wheel end and at the opposite end of the suspension for longitudinal movement therein; the suspension comprising at least one hydropneumatic suspension and damping member for receiving and damping the vertical movement of the wheel, and the suspension comprising at least two hydraulic fluid chambers separated from each other by hydraulic pistons; and the independent suspension system further includes at least one pressure accumulator; and in the independent suspen...
