Embodiment Construction

[0048] The present invention will be further described in conjunction with accompanying drawings.

[0049] A kind of off-road wheel, the connection between the parts constituting the off-road wheel is:

[0050] The screw passes through the hole on the mechanism base plate 7 and is threadedly connected with the wheel hub 6 to fix the mechanism base plate 7 on the wheel hub 6 .

[0051] The shaft of the motor 11 is connected with one end of the short shaft 9 through a shaft coupling 10 and fixed by screws.

[0052] The motor 11 is inserted into the hole in the center of the flange 12 and fixed with bolts;

[0053] The flange 12 is installed in the middle part of the inner side of the hub 6, and the motor 11, the flange 12 and the hub 6 are coaxial.

[0054] The other end of the short shaft 9 fits with the center hole of the mechanism base plate 7 and extends out of the mechanism base plate 7. The protruding part of the short shaft 9 has a square cross-section and it is connect...

Abstract

The invention discloses a cross-country vehicle wheel which relates to a wheel, in particular to an obstacle crossing mechanism of a wheel with single degree of freedom. Through the cross-country vehicle wheel, the problem that the existing wheels are bad in adaptability and basically unchangeable in effective radius is solved. A central through hole is arranged on a hub of the cross-country vehicle wheel; a flange and a mechanism basic disc are respectively arranged at the inner and outer sides; a shaft of a motor which is arranged in an inner hole of the flange penetrates through the hub and a central hole of the mechanism basic disc and then is connected with the center of a three-fork rod so as to drive the three-fork rod to rate; the forks of the three-fork rod drive three sets of completely same mechanisms; the mechanisms are respectively combined by two four-rod mechanisms; under the driving of the three-fork rod, the effects of unfolding beyond the wheel radius and folding in the hub can be realized; under the folding state, the wheel can roll normally and run at a high speed; and under the unfolding state, the obstacle crossing of the wheel can be realized via the enlarged effective radius.

Description

technical field [0001] The invention relates to an off-road wheel, in particular to a single-degree-of-freedom wheel auxiliary obstacle surmounting mechanism, which realizes the enlargement of the effective radius of the wheel and is suitable for the obstacle surmounting of vehicles in complex road conditions. Background technique [0002] With the successful launch of the Chang'e satellite, more and more attention has been paid to lunar exploration and space exploration. As for the uneven terrain and landforms that may appear on the moon, how to design the wheels of the lunar rover so that it can be better under the most difficult conditions Good walking has become a hot topic. [0003] In addition, in the field of robotics, handicapped machinery, stair climbing vehicles and other fields, there is also an urgent need for a new type of wheel that can successfully overcome various complex terrains and obstacles. [0004] The patent No. 200510046097.0 shows a dual-purpose veh...
