A high-performance screen wheel

Abstract

A high-performance screen wheel comprises a rim structure, a screen tread and pawls. The rim structure comprises a first rim, a second rim and a third rim which are coaxial; the second rim is arranged between the first rim and the third rim, radiuses of the first rim and the third rim are the same, the radius of the second rim is larger than that of the first rim and the third rim, and the three rims are connected and reinforced by reinforcing ribs. The screen tread is of a metal mesh structure covering the outer surface of the rim structure. The pawls are metal strips arranged on the screen tread and fixedly connected with the rim structure. The wheel is light and small, has simple structure and has low requirements for installation space and carrying capacity. When applied to a lunar rover, the light screen wheel has good trafficability on lunar soil of the soft lunar surface.

Description

technical field [0001] The invention relates to the field of lunar exploration vehicles, in particular to a high-performance screen wheel. Background technique [0002] The lunar surface patrol is an important project of the national lunar exploration project. The wheel is a key component of the lunar surface patrol, which realizes the movement of the lunar surface patrol on the surface of the moon, broadens the scope of the construction of the lunar exploration platform, and realizes the mobile detection. Target. At present, the wheels of the lunar surface patrol mainly have configurations such as conical wheels, elastic wheels, and pneumatic wheels. The wheels of various configurations are large in size, heavy in weight, and complex in structure, and have high requirements for carrying capacity. The wheels of the American and Russian lunar landing vehicles are respectively elastic metal wheels and rigid metal wheels. Both of these wheels have large diameters and high weig...

Problems solved by technology

At present, the wheels of the lunar surface patrol mainly have configurations such as conical wheels, elastic wheels, and pneumatic wheels. The wheels of various configurations are large in size, heavy in weight, and complex in structure, and have high requirements for carrying capacity.

The wheels of the American and Russian lunar landers are respectively elastic metal wheels and rigid metal wheels. These two wheels have large diameters and high weights, which are not suitable for the use of Chinese lunar exploration vehicles.
