Problems solved by technology

[0003] After searching the existing technical documents, it is found that the Chinese patent publication number is CN1600587A, and the title of the invention is: eight-wheel torsion bar spring suspension type vehicle-mounted mechanism. This technology discloses an eight-wheel torsion bar spring suspension type vehicle-mounted mechanism, which provides A self-contained driving wheel. Since the output of the deceleration DC motor is directly connected to the wheel, the driving torque is small, and the transmission efficiency is low when the reduction ratio is large. The rim and hub of the wheel adopt an integrated material structure, which increases the cost of the wheel. The wheel provided by the invention does not have steering function

Abstract

A driving and steering integrated wheel for the moon exploration car is mainly composed of 31 parts including rim, external and internal sealing plate, hub, drive set, connecting frame, ball bearing, two DC speed-reducing motors for drive and steering, harmonic speed reducing gear, harmonic speed reducing wave generator, etc.

Description

technical field [0001] The invention relates to a wheel in the field of mechanical technology, in particular to a wheel integrated with drive and steering of a lunar exploration vehicle. Background technique [0002] Existing mobile vehicles related to extraterrestrial exploration (moon, Mars, etc.) mostly adopt self-contained driving wheels, such as the wheel train structure of the mobile system of the series of Mars exploration vehicles Robby, Go, -For, and Rocky developed by JPL in the United States. The "Sojourner", "Sojourner", "Opportunity", "Spirit" and other Mars exploration rovers on Mars all use self-contained drive integrated wheels, that is, drive motors, gear reduction settings, speed and position detection sensors, etc. Concentrating inside the wheel simplifies the transmission system of general mobile vehicles, making the alien exploration vehicle more adaptable to the requirements of the moon, Mars and other landforms and environments. The specific structure ...
