Fig. 7 is the front elevation of wheel according to a second embodiment of the present invention.
In the first embodiment of the present invention shown in Fig. 1 to 4, provide wheel (1), it mainly is applicable to heavy duty, overland vehicle, and this vehicle is abominable and have under corrosive condition and work, as underground trackless mining condition.
Wheel (1) has a center hub (2), and this wheel hub (2) comprises that one has the median plate (3) of the octagonal steel of circular central through hole (4).This hole (4) preferably can hold bearing and/or other erecting devices, so that wheel is installed on a suitable wheel hub and/or the axle.Have continuous octagon flange on the periphery of described center hub (2), resilient supporting unit (6) is supported as base plate (5) in the plane of this flange.
Each base plate (5) is strengthened by the stay bearing plate (7) that a pair of interval is provided with, and this plate (7) extends to the adjacent surface of median plate (3) from its side near hole (4).
Annular rigid outer rim (8) with octagon structure is installed on the center hub (2) by eight annular resilient bearing sets (6).This ring-type outer rim (8) is used for eight tire section assemblies (9) are installed and the location, and they constitute a continuous wheel tyre together.
The tire assembly of each segmentation (9) has the arc elastic element (10) on the support pads (11) that is connected to erecting device, and described support pads (11) has a snyed plate (12) and a flat backboard (13).This backboard (13) fixes corresponding ring-type outer rim (8) with bolt.
Described again springing (6), Fig. 4 particularly, as can be known, each of described these devices (6) all has an annular resilient supporting member (14), the structure of its bench section is a pair of so foursquare structure, and the diagonal line of described foursquare angle is arranged in central axes and vertical two planes with described resilient supporting unit (6).
Described elastic supporting element (14) is positioned in first supporting member that a form is the cup-shaped support unit of plate-like (15), and described cup (15) is fixed to a bottom flange plate (5) and goes up and have a areal of support (16) with respect to the vertical direction cone angle at 45 of described device axis.These parts (15) are supporting the outside face (17) of described elastic supporting element (14).
The opposite inner face of described elastic supporting element (18) is that second supporting member of truncated cone shape support unit (19) supports by a form, and described parts (19) are fixed within the corresponding planar section (20) of octagon outer rim (8).
We should be understood that in the fitting process of wheel described elastic element is given compressing earlier and is arranged between the described support unit.
We will realize at an easy rate, and the structure and the structure of resilient supporting unit (6) provide compression elasticity power, make wheel have himself intrinsic vibration damping or spring performance thus, so that bear the external load that is applied on the wheel.Act on these external loads on the wheel and be by the common moment of torsion that produce, that produce by the tractive force and the braking force of vehicle of quiet and moving radial weight and when wheel is positioned at non-level or uneven road surface or be in the state of motion formed lateral loading.The structure of described resilient supporting unit (6) power that to be such so that elastic supporting element (14) in described cup-shaped support unit (15) and truncated cone shape support unit (19) clamping will act on this element is assembled with the form of pressure rather than with the form of shearing force or tensile force.
Further, can change like this, thereby regulate the spring stiffness of this material, and have damping characteristics by the inherent characteristic of the described elastic supporting element of mode (14) that increases combination.
Fig. 6 a, 6b, 6c and 6d illustrate the interchangeable version of described elastic element, and wherein described element is polygonal (octagonal), oval, avette and rectangle.
Fig. 7 represents according to interchangeable wheel of the present invention with graphic form.Wheel (31) has an outer rim (32), and this wheel rim (32) has four members that are generally Wedge-shape structures (33) that inwardly stretch out.These members (33) have the relative attachment face of direction (34), and this attachment face (34) is positioned on the radius of described wheel rim.
The center hub of wheel (35) comprises a central, circular part, stretches out four members (36) that are generally wedge shape from this part, and this member (36) is arranged in the space (37) between the adjacent member (33).
Wheel hub member (36) comprises direction facing surfaces (38), and this surface (38) are parallel with the face (34) of member (33) basically.
Being installed in described stretching out between a pair of facing surfaces (34) on member (33) and (36) and (38) is corresponding resilient supporting unit (39), this device is identical with the structure of the appropriate section of preceding first embodiment that has addressed, for this reason, will it not given any detailed description.The axis of these bearing sets (39) is with tangent with respect to the concentric circles of wheel axis.
Can give and seeing, the wheel of this structure will be used for other embodiment in identical mode.
Fig. 5 represents an interchangeable resilient supporting unit.
This device (41) mainly comprises two bearing sets shown in Fig. 1 to 4, and constitutes an integral body mutually with two truncated cone shape support units (19) of back-to-back setting, its each all support an elastic element (14).Described two elements (14) are separated by a packing ring (42) that radially extends, and this packing ring (42) is positioned at the baseplane of two truncated cone shape support units (19).And each side of this device all has a cup-shaped support unit (15).
Wheel provided by the present invention, its elastic tire section assembly can be changed and be replaced individually, and also deletrious airtyred characteristic can not occur, has enough damping behaviors simultaneously.
