Self-balancing loading wheel set for rubber crawler walking system

Abstract

The invention provides a self-balancing loading wheel set for a rubber crawler walking system. The self-balancing loading wheel set can be composed of a loading wheel pair, a transverse balance wheelset unit and a longitudinal balance wheel set unit. The loading wheel pair is composed of two loading wheels which are connected through a spherical hinge. The transverse balance wheel set unit comprises a transverse swing arm, and the two ends of the swing arm are connected with the loading wheel pair or the longitudinal balance wheel set unit respectively; the longitudinal balance wheel set unitcomprises a longitudinal swing arm hinged to the suspension, and the two ends of the longitudinal swing arm are connected with the loading wheel set or the transverse balance wheel set unit respectively. According to the self-balancing loading wheel set capable of being assembled in the modular mode, the loading wheel pair enables loads exerted on the loading wheel pair by the suspension to be evenly distributed on all loading wheels within the free movement range of a kinematic pair of the loading wheel pair, buffering is provided under the condition that the terrain is uneven, and reliablecontact between the grounding part of the crawler belt and the ground is guaranteed.

Description

technical field [0001] The invention belongs to the field of rubber crawler vehicles, and in particular relates to a self-balancing road wheel set used in a rubber crawler walking system. Background technique [0002] The passability of the rubber track walking system is closely related to its grounding pressure. Generally, under the same ground length and width of the rubber track and the same number and arrangement of road wheels, the more uniform the ground pressure distribution, the better the passability of the rubber track walking system. [0003] The ground part of the track needs to be firmly attached to the ground to ensure reliable and stable traction. However, rough terrain is the norm in the off-road environment, and the unevenness of the terrain is random and in all directions. The existing rubber crawler walking system still uses the original steel crawler walking system design, and generally considers the terrain along the longitudinal direction of the track....

AI Technical Summary

Problems solved by technology

[0004] Due to the relatively high lateral stiffness of the steel track, the design of its traveling system does not need and cannot take into account the unevenness of the terrain in the transverse direction of the track

However, there is a significant difference between the rubber track and the steel track, and its lateral stiffness and strength are lower than that of the steel track. When the terrain is uneven, the track will be locally stressed, which will cause problems such as wear, scratches, and degumming.
