Elastic bionic walking wheel of manned lunar rover

Abstract

The invention discloses an elastic bionic walking wheel of a manned lunar vehicle and belongs to the technical field of spaceflight. Connecting plates of 18 spokes in a spoke set are fixedly connectedwith the bottom surfaces of wheel surfaces of a left wheel surface set, a middle wheel surface set and a right wheel surface set in wheel surface sets through bolts and nuts respectively; the inner ends of supporting rods of 18 spokes in the spoke set are fixedly connected to the surface of a hub shaft in a hub according to the arrangement relation of the wheel surfaces of the left wheel surfaceset, the middle wheel surface set and the right wheel surface set in the wheel surface sets. The rolling resistance is small, the trafficability and smoothness are good, the load capacity is high, andthe reliability is high; the annular wheel surfaces made of a spring steel plate are adopted, elastic deformation is generated when the annular wheel surfaces are loaded, the wheel soil contact areacan be increased, the wheel traction force is improved, meanwhile, the elastic deformation can absorb energy, reduce shock and improve riding comfort, and the absorbed energy can be used for restoringthe wheel surfaces. Transverse wheel thorns arranged on the surface of the wheel surfaces can improve the thrust of lunar soil to wheels, and the traction performance and the climbing performance ofthe wheels can be improved.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to an elastic bionic walking wheel of a manned lunar rover. Background technique [0002] With the frequent activities of lunar exploration, the research of manned lunar vehicles is gradually rising. The manned lunar rover can not only carry instruments for lunar exploration, but also serve as a means of transportation for astronauts. It is an important tool for lunar exploration. As a part in direct contact with the lunar surface, the wheel plays the roles of carrying, driving, and steering, and is one of the most critical components of the lunar vehicle. The moon's special vacuum and radiation environment make rubber pneumatic tires unsuitable. The existing lunar rover wheels are generally small-sized, light-load metal wheels, and most of them are rigid wheels, which have disadvantages such as poor traction performance and poor cushioning performance, and cannot m...

Problems solved by technology

However, the striding scheme formed by traditional walking wheels is not circular rolling, which inevitably causes vertical fluctuations of the wheel center, thereby reducing the ride comfort of the vehicle, which limits the application of traditional walking wheels
