A suspension assembly (30) for a high-clearance vehicle having a forward direction of travel and a first operating clearance height, the suspension assembly (30) including an upright spindle journal (70, 72), a main suspension spindle (66, 68) received in said journal (70, 72) for rotating and sliding within said journal (70, 72), and a wheel hub mounting bracket (74, 76) being coupled to a lower end of said main suspension spindle (66, 68). In order for the spacing between tires (14, 16) at opposite sides of the vehicle to remain the same, with or without the usage of the spacer assemblies (30), each spacer assembly (30) includes a coupler spindle (82) extending parallel to, and offset inwardly from, a pivot axis of the associated main suspension spindle (66, 68) by a distance calculated to result in the desired tire spacing, this coupler spindle (82) being received in the bore at the top of the associated wheel hub mounting bracket (74, 76).

In a vehicle (2) as a multi-directionally-steered self-driving vehicle with mechanical and/or electrical/electronic control and corresponding coupling of the modules (2) which in each case form the vehicle and have driving axles, wherein each driving axle (1), at the two longitudinal sides (3, 4) of a module (2), is assigned and is rigidly fastened to in each case one bogie (5; 6) with wheels (7; 8), and a substantially vertical central axle (9; 10) is assigned and is rigidly fastened to a rotary plate (13; 14) which is mounted on a module (2) so as to be rotatable about a central and substantially vertical steering rotary axle (9'; 10'), and said control provides the in each case required rotary positioning of the steering rotary axles (9'; 10') during driving by rotating the rotary plates (13; 14), the vertical central axles (9; 10) of the two bogies (5; 6) of a driving axle (1) are arranged eccentrically, in each case oppositely with respect to one another by an identical length value (T), with respect to the central steering rotary axles (9'; 10') of the rotary plates (13; 14), such that in the event of a mutually opposite rotation of the rotary plates (13; 14) by 180 degrees about their central steering rotary axles (9'; 10'), the bogies (5; 6) of said driving axle (1) with their wheels (7; 8) can be pivoted back and forth from a minimum width (b as per Fig. 1 and 2), in which the central axles (9; 10) of the bogies (5; 6) are brought as close to one another as possible, by a maximum of in each case double said length value to the respective longitudinal side (3; 4) of the module (2), wherein said double corresponds in each case to the double radial spacing between a steering rotary axle (9' or 10') of a rotary plate (13 or 14) at one side and the central axle (9 or 10) of the associated bogie (13 or 14) at the other side, in such a way that widening of the respective driving axle (1) or else of the entire modular vehicle (2) can be carried out to a maximum width (B = b + 4T as per Fig. 3 and 4) and a narrowing can be carried out again to the minimum width (b).
摘要:
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.
摘要:
An aerostatic suspension system (1) for rolling equipment and vehicles that takes advantage of atmospheric pressure to create, by means of cylinder and piston sets, forces that are transmitted by levers having an adjustable point of application of force and that at their distal ends are articulated with wheel support rods. Said forces, acting individually on each wheel, aerostatically suspend the weight plus its load of the equipment or vehicle.

The invention concerns a transport arrangement (1) for running/movement on uneven surfaces, comprising a frame (5) which on two opposite sides is provided with at least three, preferably four or more, successively arranged actuator legs (2), said actuator legs (2) comprising an upper end (3) and a lower end (4), to which upper end (3) there is fastened an upper frame (6), and to which lower end (4) there is fastened a movement device (7) for bringing about the forwards and backwards movement of the transport arrangement. Each actuator leg (2) comprises a control means (8) and a turning means (9), where the control means (8) brings about a displacement of the movement device (7) which is vertical in relation to the upper frame (6), and the turning means (9) brings about a movement of the movement device (7) which is circular in relation to the running surface. Activation of the three-dimensional movement of the movement device (7) is brought about with registration means (10). The invention also concerns a method of controlling a transport arrangement (1). The transport arrangement achieved hereby is one which is able to identify a given obstacle and exercise the necessary action, and where during the movement of the transport arrangement its frame(s) remain immovable.

An oscillating axle device, for use with a wheelset for the transportation of heavy loads, comprising an axle (1) which at each end is provided with at least one wheel, said axle being pivotably supported by means of a pin (4) mounted in a bracket (3) connected to a frame. The insert end of said pin is provided with screw-thread (6) for fixing the pin into the bracket. Said pin is provided with a conically section (7) extending from the screw thread towards the middle section having a larger diameter and supporting the wheel axle. Said conical section (7) is fittingly received in a corresponding conical bore (11) in the bracket (3).
