摘要:
A wheel with a suspension system being connectable to a vehicle, like a wheel chair, comprises a hub (38) and a rim (34) rotatable about the axle (42) of the hub (38). Between the hub (38) and the rim (34), a number of support members (40) is located. The support members (40) are adapted to retain the distance when stressed up to a threshold value and recoverly alter the distanced when stressed over this threshold value. According to the invention, the support members (40) are comprising spring elements (50), damping strokes by compression if the support member (40) is compressed or elongated. The spring elements (50) are preferably preloaded.
摘要:
A method for producing designs involves receiving a request to create a design on the surface of an extraterrestrial body, transmitting a control signal to a device on a vehicle on the extraterrestrial body, the control signal causing the device to create the design, and receiving an image signal providing an image of the design created on the surface. A device for producing the designs includes a surface altering tool configured to rearrange material on the surface. The tool may be provided as a configurable-tread rover wheel that includes a wheel hub having radially-extending channels, and tread elements supported in the channels that are selectively articulatable under the control of a control module to form a tread pattern corresponding to a design intended to be produced. The tread elements may be selectively extended or retracted by operation of an array of solenoids controlled by the control module.
摘要:
A wheel for a celestial running vehicle which enables the celestial running vehicle to sufficiently exhibit its desired running performance by maintaining a sufficient ground contact length, as well as reducing the wheel maximum width and the number of the sliding portions. The celestial body vehicle wheel (1) is mounted on a celestial body running vehicle and includes, a hub body (2) rotatable about a rotation axis, a grounding member (3) arranged radially outside of the hub body (2) and rotatable about the rotation axis while contacting a celestial body surface, and a load bearing device (4) arranged between the hub body (2) and the grounding member (3) for bearing radial load, the load bearing device (4) including, a plurality of first support members (5) arranged circumferentially to extend radially outward from the hub body (2) and terminate short of the grounding member (3), a plurality of second bearing members (6) arranged circumferentially to extend radially inward from the grounding member (3) and terminate short of the hub body (2), and elastic members (7) for connecting the first support members (5) and the second support members (6) to each other, wherein, under the radial load, the elastic members (7) are elastically deformed, and the first support members (5) and the second support members (6) are relatively displaced in directions approaching each other.
