DETAILED DESCRIPTION

[0018] FIG. 1 is a front view of a vehicle axle according to one embodiment at an independent suspension state.

[0019] FIG. 2 is a perspective view of the vehicle frame including the vehicle axle of FIG. 1 at the independent suspension state.

[0020] A vehicle axle 10 according to one embodiment of the invention includes a left axle 12L, being pivotally connected, via a hinge 50L, to the left vehicle wheel hub 14L; a right axle 12L, being pivotally connected, via a hinge 50R, to the right vehicle wheel hub 14R; and a connector 20, being pivotally connected to left axle 12L and to right axle 12R, such as by hinges 28.

[0021] At this state, connector 20 is anchored to the center 60 of chassis 24 of the vehicle, and connector 20 provides free rotation of left axle 12L in relation to right axle 12R, for swinging therebetween, while being anchored to chassis 24. Thus, axles 12L and 12R form at this state an independent suspension.

[0022] FIG. 3 is a front view of the vehicle axle of FIG. 1, at a dependent suspension state.

[0023] FIG. 4 is a perspective view of the vehicle frame including the vehicle axle of FIG. 3 at the dependent suspension state.

[0024] At the dependent suspension state, left axle 12L is yet pivotally connected to left wheel 14L; and right axle 12L is pivotally connected to right wheel 14L.

[0025] However, at this state left axle 12L and right axle 12R are rigidly connected one to the other, forming together a straight axle or any fixed angle therebetween (herein named rigid axle).

[0026] Further at this state, connector 20 is separated from chassis 24 of the vehicle, thus the rigid axle formed by left axle 12L and right axle 12R, is not held by chassis 24.

[0027] FIG. 5 is the front view of the axle of FIG. 1 at the independent suspension state of FIG. 1, including a mechanism according to one embodiment, for providing the independent suspension state of FIG. 1 and the dependent suspension state of FIG. 3.

[0028] A mechanism 52A for providing the two states, may include a ring 54L extending from left axle 12L; a ring 54R extending from right axle 12R; a bar 56 fixed to connector 20, for being rotated by rotation of connector 20; an extension 58L, such as motorized, hydraulic or pneumatic, for being extendable from the left end of bar 56 towards left ring 54L; an extension 58R, for being extendable from the right end of bar 56 towards right ring 54R; and a ring 22, for being extendable from connector 20, for allowing binding center 60 of chassis 24 thereto.

[0029] At the independent suspension state of FIG. 5, extensions 58L and 58R are not inserted into rings 54L and 54R respectively, thus bar 56 freely rotates with connector 20. However, this rotation of bar 56 has no effect on any of axles 12L and 12R, thus axles 12L and 12R are independent of one another.

[0030] At this independent suspension state of FIG. 5, ring 22 grips center 60 of chassis 24, thus the independency of axles 12L and 12R one from the other is limited by chassis 24.

[0031] FIG. 6 is the front view of the axle of FIG. 1 at the dependent suspension state of FIG. 3, including the mechanism of FIG. 5.

[0032] At the dependent suspension state of FIG. 6, extensions 58L and 58R are inserted into rings 54L and 54R respectively, thus left axle 12L and right axle 12R are rigidly connected one to the other, forming together the rigid axle of FIG. 3.

[0033] At this dependent suspension state of FIG. 6, ring 22 releases chassis 24, for releasing the rigid axle therefrom.

[0034] FIG. 7 depicts another mechanism for providing the dependent and independent states.

[0035] FIG. 8 is an exploded view of the mechanism of FIG. 7.

[0036] Another mechanism 52B for providing the two states, may include a motor 78 for rotating a peripheral cog 32, for rotating bolts 40 for advancing nuts 34 each within and along a shaped hollow shell 38, being rigidly fixed to axles 12R and 12L, thus rotating them one in relation to the other to obtain the rigid axle of FIG. 3. [0037] Numeral 10 denotes the vehicle axle according to one embodiment of the invention; [0038] 12L,12R: left and right axles respectively; [0039] 14L,14R: left and right wheel hubs respectively; [0040] 18: vehicle frame; [0041] 20: connecting element; [0042] 22: mechanism, which may include an opening and closing ring for binding or releasing the binding; [0043] 24: vehicle chassis; [0044] 28: hinges; [0045] 29,30,31: cogs; [0046] 32: peripheral cog; [0047] 34: nut; [0048] 36: ring; [0049] 38: shaped hollow shell; [0050] 40: bolt; [0051] 42: vehicle springs/suspensions; [0052] 50L,50R: hinges; [0053] 52A,52B: mechanisms; [0054] 58L,58R: hinges; [0055] 60: center of chassis 24; [0056] 78: motor.
