Detailed Description
As shown in fig. 1 and 2, a wheel for driving on a complex road surface includes a circular hub 1 connected to a driving shaft, and a plurality of elastic unit wheels 2 are uniformly distributed in a radial shape around the circumference of the circular hub 1 with respect to the center.
Each elastic cell wheel 2 includes a piston cylinder 21, a link 22, and a cell rubber tread body 23.
Wherein the cylinder body 211 of the piston cylinder 21 is mostly positioned in the circular hub 1 and fixedly connected with the latter, and the outer end of the cylinder body 211 is exposed out of a part of the hub 1. The cylinder body 211 is provided with a piston cavity 212, the piston cavity is provided with a piston 213 to divide the piston cavity into an inner cavity 212a and an outer cavity 212b, the inner end of the inner cavity 212a is provided with an air outlet 214 communicated with the outside, and the air outlet 214 is closed or opened by a plugging device 215.
The connecting rod 22 is composed of a straight rod 221 and a connecting plate 222 vertically arranged relative to the straight rod, the rear end of the straight rod 221 extends into the piston cylinder 21 and is fixedly connected with the piston 213, and the inner end and the outer end of the piston 213 are respectively provided with a return spring 216a and a return spring 216b, so that the piston 213 and the piston cavity 212 form a movable fit relationship.
Here, in order to ensure the air tightness of the outer chamber 212b, a sealing rubber plug 217 is disposed at a connection portion of the straight rod 221 and the cylinder body 211.
In this embodiment, the illustrated plugging device 215 includes a linear motor 2151, and a plug 2152 is provided on an output shaft of the linear motor 2151. In operation, the linear motor 2151 is operated to drive the plug 2152 to extend or retract, so as to adjust the opening of the air outlet 214 or control the opening and closing of the air outlet. During the running of the wheel, the opening and closing or the opening of the air outlet holes 214 can be controlled according to the load condition and the road surface condition, so that the overall elastic rigidity of the elastic unit wheel 2 can be adjusted. In practice, other plugging devices may be used as long as the opening of the air outlet 214 can be controlled.
The unit rubber tread bodies 23 are mounted on the outer end faces of the connection plates 222. The cross-sectional shape of the unit rubber tread body 23 is trapezoid-like, and the top angles 231 on both sides of the outer end thereof are arranged to be arc chamfers, so as to reduce the ground resistance of the unit rubber tread body 23 during rolling and improve the overall rolling performance of the tire.
