Structural form of crawler walking device
Our company mainly produces excavator chassis components, such as: rollers, supporting rollers, tracks, idlers, loose rings, lower rollers, sprockets, steel tracks, upper rollers, track chains, track groups, track chains Rods, track shoes, rollers, track shoes
1 Features of crawler-type walking device
As a walking device, the crawler has this obvious working characteristic. First, strong power, second, good stability, third, flexible operation, coupled with the ability to complete various tasks in changing and complex working conditions, especially in mountainous and other working conditions, its off-road performance has been brought into full play. . Therefore, most of our country and foreign countries use crawler walking devices.
In order to develop standardization, my country’s crawler-type walking device has made improvements in standardization technology, that is, adopting the principle of standardization to specify excavator parts, so that the production capacity can be improved through the interchangeability of parts, and the price of products can be reduced, which is also a great improvement. cost-effective.
The crawler-type walking device also has its own shortcomings, such as serious power consumption, slow walking speed, too much output torque, etc., and it cannot be used for long-distance walking and transportation. Even so, the crawler-type traveling device has been widely used by virtue of its own obvious working characteristics and performance, and has been greatly affirmed and recognized.

The composition of the crawler walking device
When the hydraulic excavator is running, there is a certain pulling force between the power unit and the guide wheel. This pulling force is brought by the driving wheel, so that the track has a tendency to fall down under the action of the force. The support of the supporting wheel The function, the adhesion of the crawler, enables the crawler to bite the ground, prevents the deviation and usurpation of the crawler, and ensures that the excavator can overcome various resistances to move forward and work normally. The crawler belt is tightly wound on the guide wheel, and the meshing with the driving wheel on the machine enables continuous and normal driving on various road surfaces.
When the excavator is running, it is independently carried out through the walking drive device. The two tracks each generate their own movement, enabling steering and straight-line travel.
