Problems solved by technology

[0002] For large crawler vehicles such as crawler cranes, the weight of the whole machine is generally relatively large. In order to increase the grounding area and reduce the grounding specific pressure, the length and width of the track frame and the track are generally increased as much as possible, but the result is that, When the track frame performs single-leg steering, due to poor ground conditions or changes in the center of gravity, the turning resistance moment often exceeds the torque provided by the travel reducer, and the tracked vehicle cannot turn.
[0003] In order to solve the problem that tracked vehicles cannot turn, the commonly used solution is to replace large-scale motors and travel reducers to increase their output torque, but this will cause a substantial increase in cost and waste of energy. Therefore, the existing The technical solution only solves the problem of being able to turn, but it is still not the best way to realize the easy turning of tracked vehicles

Embodiment 1

[0040] figure 1 Schematic diagram of the structure of the crawler-type traveling mechanism provided by the embodiment of the present invention, figure 2 It is a schematic diagram of the partial structure of the crawler-type traveling mechanism provided by the embodiment of the present invention, image 3 For the structural diagram of the inner box of the crawler-type traveling mechanism provided by the embodiment of the present invention, please refer to Figure 1-3 , this embodiment provides a crawler-type walking mechanism, including an outer box 1, an inner box 2 and a crawler belt 3, the inner box 2 is set inside the outer box 1, and the crawler belt 3 is set on the inside of the outer box 1 On the outer box 1;

[0041] The bottom of the outer box 1 is provided with a first roller 11, and the bottom of the inner box is provided with a second roller 21; the outer box 1 and the inner box 2 are provided with A driving structure 4, the driving structure 4 is used to drive ...

Embodiment 2

[0046] This embodiment has an overall structure similar to that of Embodiment 1, the difference is that this embodiment provides the installation position of the drive structure and the specific structures of the inner box and the outer box.

[0047] see Figure 1-3 , in this embodiment, the fixed end of the driving structure is arranged on the inner side of the top wall of the outer box 1, the crawler frame 14 of the outer box 1 is provided with a mounting plate 15, and the driving structure 4 is arranged on the mounting plate 15, the driving end of the driving structure is close to the outer side of the top wall of the inner box 2; the driving structure 4 is used to press down the top of the inner box 2 when the running mechanism turns. The wall makes the outer box body 1 lift upward relative to the inner box body under the action of the supporting reaction force of the driving structure. The driving structure 4 of this embodiment is an oil cylinder, and the oil cylinder is...

Embodiment 3

[0053] This embodiment provides a crawler-type traveling mechanism, which has an overall structure similar to that of Embodiment 1, except that this embodiment provides a crawler-type traveling mechanism with an intelligent steering function.

[0054] see Figure 1-3 , in this embodiment, the crawler-type traveling mechanism also includes a level detector 6 and a controller 7, the controller is connected to the drive structure, and the level detector 6 is used to detect the offset of the center of gravity of the crawler vehicle, The level detector 6 is also used to send the offset to the controller, and the controller 7 is used to control the driving structure action according to the offset;

[0055] The controller 7 is also used to control the drive structure to press down the top of the inner box 2 when the offset is greater than a first preset value, so that the outer box 1 is relatively The inner box body 2 is lifted upwards, and keeps the track under the second roller 21...

Abstract

The invention discloses a track type running mechanism and a track vehicle. The track type running mechanism comprises an external box body, an internal box body and a track; the internal box body isembedded in the external box body; the track is arranged on the external box body in a sleeving manner; a first supporting wheel is arranged at the bottom of the external box body; a second supportingwheel is arranged at the bottom of the internal box body; a driving structure is arranged between the external box body and the internal box body; and the driving structure is used for driving the external box body to rise relative to the internal box body during turning of the running mechanism so that the external box body drives the track under the first supporting wheel to be separated from the ground and drives the track under the second supporting wheel to be kept in contact with the ground. When the track type running mechanism and the track vehicle turn, the external box body drives the track under the first supporting wheel to be separated from the ground and drives the track under the second supporting wheel to be in contact with the ground; and therefore, the contact length andarea between the track and the ground are reduced, the turning resistance is reduced, and the lightweight turning of the track type running mechanism is realized.
