Embodiment 1

[0038] Such as figure 1 and figure 2 As shown, the present invention provides a wheel body internal pressure control system, including a pressure sensor 10, a controller 20 and a driving device. controller 20, the controller 20 is used to receive the pressure value of lubricating oil in the wheel body transmitted by the pressure sensor 10 and send a deceleration signal to the driving device when the pressure value of the lubricating oil in the wheel body is higher than the preset threshold value, and the driving device is used according to the controller 20 The deceleration signal reduces the walking speed. Specifically, the pressure sensor 10 transmits signals to the controller 20, and a wireless transmission method may be selected.

[0039] The internal pressure control system of the wheel body provided by the present invention detects the pressure value of the lubricating oil in the wheel body and transmits the pressure value of the lubricating oil in the wheel body to t...

Embodiment 2

[0051] Such as image 3 As shown, the present invention provides a construction machine, including the wheel body internal pressure control system in any one of the foregoing embodiments.

[0052] Since the engineering machinery provided by this embodiment includes any one of the above-mentioned wheel body internal pressure control systems, it has the technical effect of any one of the above-mentioned wheel body internal pressure control systems, and will not be repeated here.

[0053] The construction machinery also includes crawler belts 1, guide wheels 2, tensioning devices 3, supporting wheels 4, supporting sprockets 5, and driving wheels 6. The driving wheels 6 are arranged at the front or rear end of the vehicle body. Correspondingly, the guide wheels 2 are set At the rear end or front end of the car body, the car body is also provided with a drag chain wheel for supporting the track 1 and a roller 4 for supporting the car body. The track 1 is wound around the track roll...

Embodiment 3

[0055] Such as Figure 4 As shown, this embodiment provides a wheel body internal pressure control method using the wheel body internal pressure control system in any one of the preceding embodiments, including the following steps:

[0056] The pressure detection sensor detects the pressure value of lubricating oil in the wheel body, and transmits the pressure value of lubricating oil in the wheel body to the controller;

[0057] The controller compares the lubricating oil pressure value in the wheel body with the preset threshold value;

[0058] When the lubricating oil pressure in the wheel body is greater than the preset threshold, the controller controls the driving device to decelerate until the lubricating oil pressure in the wheel body is less than or equal to the preset threshold.

[0059] The wheel body internal pressure control method provided in this embodiment detects the pressure value of the lubricating oil in the wheel body and transmits the pressure value of t...

Abstract

The invention provides a wheel body internal pressure control system, construction machinery and a wheel body internal pressure control method of the wheel body internal pressure control system, and relates to the technical field of construction machinery lubrication. The internal pressure control system of the wheel body includes a pressure sensor, a controller and a driving device. The pressure sensor is used to detect the pressure value of the lubricating oil in the wheel body and transmit the pressure value of the lubricating oil in the wheel body to the controller. The controller is used to receive the wheel pressure value transmitted by the pressure sensor. The lubricating oil pressure value in the wheel body sends a deceleration signal to the driving device when the lubricating oil pressure value in the wheel body is higher than the preset threshold, and the driving device is used to reduce the walking speed according to the deceleration signal of the controller. The invention solves the technical problem that the internal pressure of the wheel body cannot be effectively controlled, and achieves the technical effect of effectively controlling the pressure value of lubricating oil in the wheel body.

Description

technical field [0001] The invention relates to the technical field of lubrication of construction machinery, in particular to a wheel body internal pressure control system, construction machinery and a wheel body internal pressure control method of the wheel body internal pressure control system. Background technique [0002] In crawler-type construction machinery, the idler is an important part to maintain the proper tension of the track. In production practice, due to the high oil temperature in the guide wheel, the lubricating oil will be diluted seriously, the drag reduction effect of the bearing will be reduced, and the wear speed of the bearing will be significantly accelerated. [0003] Moreover, excessive pressure inside the wheel body will significantly increase the possibility of lubricating oil leakage. When the lubricating oil leaks, the wear of the bearing will also increase significantly. [0004] In the after-sales statistics of construction machinery, in a...
