A plurality of load bearing wheel sets, a multi-dimensional balance suspension and a linear-moving type following tension structure or a fixed type tension structure are adopted, a bend steering function and a power-assisted steering function are achieved, all components and the integrated wheel are modularized, quick wheel and crawler exchanging of high-speed and heavy-duty cross-country engineering vehicles can be achieved, ground pressure of the vehicles is substantially reduced, adhesive force is improved, smoothness, stability and passing ability of the vehicles on rough topography are improved, stable traction is maintained, working reliability is improved, and using and maintaining are convenient. Meanwhile, different structures of the modularized rubber crawler wheel can be selected according to vehicle loads.

A therapeutic device, such as an exercise device, includes the principles of osteogenic repair by incorporating a loading mechanism into the exercise device. By doing so, the therapeutic device provides an increased osteogenic effect, thereby enhancing the benefits of the therapy. As an example, a exercise device includes a support surface for supporting all or part of the bodily tissue of an individual using the device. A linear or rotary loading mechanism associated with the frame or a rotational element of the exercise device drives the support surface at a selected load and frequency, thereby inducing mechanical loading of bodily tissue adjacent to the support surface sufficiently to facilitate the growth, development, strengthening, and/or healing of bone tissue. The loading mechanism may be incorporated into any exercise device, including standard exercise devices such as rowing machines, stair climbing machines, elliptical trainers, bicycles, cross-country ski trainers, treadmills, or weight trainers.

An apparatus supporting “dry land” simulation of the diagonal stride cross-country skiing technique. The apparatus may include a roller ski comprising at least two wheel configured to roll on a surface and a stop connected to the roller ski. The stop may selectively engaging at least one of the surface and the at least two wheels in response to a force of at least a threshold magnitude urging the roller ski toward the surface to resist rearward roll of the roller ski on the surface. The resistance to rearward roll may vary with the force.

The invention relates to the technical field of computers, and discloses an identity verification method and system, which can realize cross-country identity verification on the premise of meeting data outbound management and control of various countries. The method comprises the following steps that: an application which needs an identity verification service sends a first request to a digital identity client, wherein the first request comprises an identity and first information; the application receives signature information returned by the digital identity client and a public key corresponding to the identity identifier, wherein the signature information is obtained by allowing the digital identity client to a private key corresponding to the public key to digitally sign the first information; the application sends a second request to a first node of the first block chain, and the second request comprises signature information and a public key, so that the first node performs verification according to the signature information and the public key; and the application receives a verification result of the verification returned by the first node, and carries out identity verification according to the verification result.

A stud for a crawler pertaining to crawler-type vehicles, especially ski slope grooming vehicles or appliances for tracing cross-country ski runs, the stud having a carrier provided with a portion for mounting an inserted bar, wherein the mounting portion has two parallel legs interconnected by a connecting element arranged on the crawler, and arranged at an angle, at a distance from the bearing surface of the stud; wherein the bar is partially glued and/or welded in the mounting portion.

A release binding is shown for releasably attaching a ski boot to a telemark or cross-country ski having a load spool with a circumferential groove and a substantially elliptical holding portion attached perpendicular to the bottom of a toe plate. A release plate having a load spring with two sides is attached to the ski. To assemble the boot on the ski, a lever is moved to an unlocked position placing the minor axis of the ellipse of the load spool perpendicular to the two sides of the spring. After the boot is assembled to the ski, the lever is moved to a locked position which moves the major axis of the ellipse of the spool until it is perpendicular to the sides of the spring.

The invention relates to the technical field of vehicle experiments, in particular to a road simulation testbed for a wheel.The road simulation testbed comprises a vertical excitation system coaxially connected with a wheel to be tested and a revolving drum system arranged below the wheel to be tested; the revolving drum system comprises a revolving drum and a first drive device for driving the revolving drum to rotate, and the outer cylindrical face of the revolving drum is in rolling contact connection with the outer circumferential face of the wheel to be tested so that the driving state on a road of a vehicle can be stimulated; the vertical excitation system comprises a hanger bracket system, the wheel to be tested is mounted on the hanger bracket system, so that the dynamic load of the wheel to be tested in the driving process of the vehicle in the vertical direction is stimulated by exerting perpendicular drive on the hanger bracket system.The first drive device drives the revolving drum, drive and loading of the torque of the wheel to be tested are achieved, the complex dynamic load of the wheel in the vertical direction is represented through the hanger bracket system, targeted to the characteristic of complex dynamic load of an off-road vehicle, the stress of the wheel passing through complex cross-country road conditions is stimulated, and the straight travel working condition of wheels of the off-road vehicle is effectively stimulated.
