Abstract

The invention is a crawler wheel which can realize the mutual conversion between the wheel type and the crawler type state, which includes a fixed-length crawler belt and a driving device. The driving device includes a cage and a drive brake assembly. The cage includes an inner fixed bracket and an outer movable bracket. , the outer movable bracket also includes a support plate, a pinion gear telescopic rod and a large gear telescopic rod; an auxiliary support rod is connected between the outer movable bracket and the inner fixed bracket; the drive brake assembly includes a center drive gear, a crawler drive gear and The crawler drive pinion, the center drive gear is fixed between the left and right sides of the inner fixed bracket, the crawler drive large gear is fixed between the left and right sides of the large gear telescopic rod, and the crawler drive pinion is fixed between the left and right sides of the pinion telescopic rod , the track drive bull gear and the track drive pinion are meshed with the fixed-length track respectively. The invention can change the state according to the road condition and terrain, comprehensively improve the rolling performance, load capacity, stability and timeliness, and further enhance the practicability.

Description

technical field [0001] The invention belongs to the technical field of vehicle walking, and in particular relates to a crawler wheel which can realize the mutual conversion between the wheel type and the crawler type state. Background technique [0002] The track wheel is a wheel-track integrated traveling mechanism. Through the change of the shape of the traveling mechanism, the conversion between the wheel type and the crawler type is realized. It is mainly used to improve the grounding of the traveling mechanism and the ground, that is, to use the wheel on a flat hard road. Drive in crawler state to increase the driving speed, and drive in crawler state on rough and soft roads to improve passability. [0003] At present, several representative patents related to the wheel-track integrated traveling mechanism that have been authorized in China include: a crawler wheel that can realize mutual conversion between wheel and track-type states. The authorized announcement number...

Problems solved by technology

[0003] At present, several representative patents related to the wheel-track integrated traveling mechanism that have been authorized in China include: a crawler wheel that can realize mutual conversion between wheel and track-type states. The authorized announcement number is CN 105882774 B. The main characteristics of its structure are The cage is deformed, and the brake assembly is driven to drive the crawler to rotate. The design load capacity of this mechanism and the timeliness of deformation stability are good, but because the center shaft is installed eccentrically in the wheel state, it does not have rolling performance; in addition, it also has There is a wheel-shoe conversion mechanism whose authorized announcement number is CN 202358210 U. The main feature of its structure is the variable-diameter drive gear. Due to the peripheral structure of the load-bearing structure, the load-bearing capacity is good, but because the gear-diameter change process is not continuous, Therefore, if it is deformed with an automatic deformation device, the deformation stability and timeliness of the mechanism are poor

[0004] The wheel-track integrated driving mechanism is still in the exploratory stage. The main limiting factors are weak load capacity caused by structural design, unstable deformation caused by control technology, and untimely deformation caused by sensing technology.
