Embodiment Construction

[0022] figure 1 , figure 2 , Figure 5 , the wheel includes a relatively movable hub 2 and a rim 4, which are connected by n (n=1, 2, 3, 4, . . . ) helical springs 3 . The springs 3 are evenly distributed about the center of the wheel, that is, after the front view of the wheel is rotated by an angle of 2π / n around the central axis, n springs 3 overlap with the original n springs 3. The two ends of the spring 3 are fixedly connected or hingedly connected with the rim 4 or the hub 2 . In the figure, the outer end ring of the spring 3 is fixed on the support plate 14 rigidly connected with the rim 4 through the end ring attachment (screw 20, nut 19), so the outer end ring and the rim 4 are fixedly connected. The inner end ring is rigidly connected with the end ring accessories (screw 13 , nut 18 ), that is, the nut 18 is tightened, and the inner end ring is fixed on the screw 13 . The screw 13 has a hole, and is sleeved on a pin 12 that is rigidly connected with the wheel h...

Abstract

The invention relates to a wheel. The wheel comprises a hub 2, a rim 4 and a plurality of springs 3 for connecting the hub 2 and the rim 4 and transmitting radial force, and is characterized in that: the hub 2 and the rim 4 are also connected through a two-dimensional zero angle displacement guide which is a two-stage four-connecting rod; the two ends of each spring 3 are fixed or hinged to the hub 2 and the rim 4; and a tension or compression spring 3 with initial tension or initial pressure also can be connected to the hub 2 and the rim 4 through a connecting piece with zero tension rigidity or zero compression rigidity. When the wheel runs on the flat ground and is not subjected to impact force, the stress of the spring 3 is lower than the initial tension or the initial pressure, and the rigidity of the wheel is equal to the radial rigidity of a tire; when the wheel is subjected to the impact force, the tension or compression spring 3 is further tensioned or compressed, and the rigidity of the wheel can be far lower than the radial rigidity of the tire, so a vehicle is not provided with a suspension; and the wheel is particularly suitable for an automobile using an integral axle or a two-wheel vehicle using an integral frame.

Description

technical field [0001] This patent relates to wheels, which is an improvement to the former Chinese patent 021113270. Background technique [0002] The above-mentioned patent 021113270 separates the wheel hub and the rim of the wheel, and a spring is used to transmit radial force between the two, which reduces the radial stiffness of the wheel, but the longitudinal stiffness of the wheel also decreases at the same time. Contents of the invention [0003] The purpose of this patent is to provide a wheel with the hub and the rim connected by springs. Compared with the ordinary wheel with the rigid connection between the rim and the hub, the radial stiffness is reduced, but the longitudinal and lateral stiffness is unchanged. [0004] The purpose of this patent is achieved in this way. The relatively movable hub 2 and rim 4 are connected by a 2-dimensional zero-angle displacement guide. Stage transmission, so that the angular displacement between the hub 2 and the rim 4 is z...
