Walking device of slewing bearing

Abstract

The invention provides a walking device of a slewing bearing. The device comprises a vehicle frame, at least three supporting leg structures, the supporting leg structures comprise wheels and wheel supporting frames, the wheel supporting frames are connected with the vehicle frame through slewing bearings and used for achieving rotatable connection between the wheel supporting frames and the vehicle frame, the slewing bearings comprise inner rings and outer rings which can be rotated relative to each other, transmission teeth are arranged on the outer surfaces of the outer rings, the transmission teeth are connected with a transmission mechanism in a ratcheting manner, the transmission mechanism is connected with a slewing drive, the rotary control of the slewing bearings is achieved by the slewing drive through the transmission mechanism, the wheels are driven by an independent driving device, and the center lines in the vertical directions of the wheels keep a certain distance from the central axis lines of the slewing bearings. By means of the walking device, steering control is strength-saving, translation turning can be achieved, blind areas of operation are less, the damage on crops is effectively reduced, and wide-width operation can be achieved.

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a slewing support walking device. Background technique [0002] Traditional agricultural machinery traveling devices are mainly four-wheeled traveling devices. In order to achieve small resistance and stable steering when four-wheeled traveling devices turn, the steering system is required to ensure that all wheels are purely rolling when turning. Obviously, this is only It can only be realized when the axes of all wheels intersect at one point, that is, only when the deflection angle of the inner wheel is greater than that of the outer wheel, which requires a complicated steering mechanism for angle adjustment and compensation, and the structural cost of the steering mechanism is relatively high; at the same time, The compensation angle in actual application is often not accurate enough.

[0002] Traditional agricultural machinery traveling devices are mainly four-wheeled traveling devices. In order to achieve small resistance and stable steering when four-wheeled traveling devices turn, the steering system is required to ensure that all wheels are purely rolling when turning. Obviously, this is only It can only be realized when the axes of all wheels intersect at one point, that is, only when the deflection angle of the inner wheel is greater than that of the outer wheel, which requires a complicated steering mechanism for angle adjustment and compensation, and the structural cost of the steering mechanism is relatively high; at the same time, The compensation angle in actual application is often not accurate enough. At least one of the two front wheels will slip or skid slightly, and the resistance to steering is relatively large, making it difficult to turn. At the same time, the steering radius of the traditional four-wheel walking device is relatively large. There is a large blind area during operation, and its production efficiency cannot meet the needs of the operation; in addition, due to structural limitations, the width of the existing traveling device is narrow, the span is small, and the one-time operation range is limited, which cannot meet the rapid operation of large-area fields. need
