Reversible planetary wheel set running mechanism

Abstract

The invention discloses a reversible planetary wheel set running mechanism. The reversible planetary wheel set running mechanism comprises a driving shaft capable of rotating in double direction and a planetary wheel set. The driving shaft is installed on a vehicle frame. The planetary wheel set is installed on the driving shaft. A one-way bearing and a center driving gear are installed on the driving shaft in a sleeving mode. The planetary wheel set comprises a planetary frame, a planetary wheel and a reverse transmission device. The planetary wheel and the reverse transmission device are fixed on the planetary frame. The planetary frame is connected with an outer ring of the one-way bearing. The planetary wheel is connected with the center driving gear through the reverse transmission device. The reversible planetary wheel set running mechanism has good heading and obstacle crossing functions and is simple in structure, easy to control and suitable for application of all-terrain vehicles.

Description

technical field [0001] The invention relates to a reversible planetary wheel set traveling mechanism, which belongs to the technical field of all-terrain vehicles. Background technique [0002] The problems to be solved by all-terrain vehicles include adaptability to complex environments, good obstacle-surmounting ability and certain speed. At present, common all-terrain vehicle traveling mechanisms are divided into leg type, crawler type, wheel type, compound type and the like. Although the leg-type traveling machine has good adaptability and strong obstacle-crossing ability, it has many degrees of freedom, too complicated structure, low moving efficiency, difficult control, and high energy consumption; the crawler-type traveling machine has good obstacle-crossing ability. Performance, passing performance is high, but the speed is slow and the wear on the track is too large when turning; the wheeled traveling machine is widely used because of its strong bearing capacity, f...

AI Technical Summary

Problems solved by technology

Although the leg-type traveling machine has good adaptability and strong obstacle-crossing ability, it has many degrees of freedom, too complicated structure, low moving efficiency, difficult control, and high energy consumption; the crawler-type traveling machine has good obstacle-crossing ability. Performance, passing performance is high, but the speed is slow and the wear on the track is too large when turning; the wheeled traveling machine is widely used because of its strong bearing capacity, fast moving speed, simple control and flexible steering; the compound traveling machine has multiple sets The transmission system, structure and control are relatively complex but suitable for some special environments

The existing technology also uses three planetary gear sets for driving, which has good obstacle-crossing ability and is suitable for driving environments with uneven surfaces, but there are problems such as limited obstacle-crossing function and complicated control.
