Abstract
The invention discloses a bulldozer steering fault detection method. The bulldozer steering fault detection method includes a, detecting oil pressure of hydraulic systems of steering clutches; b, detecting a steering pump and a steering valve; c, detecting an O-shaped seal ring, laterally connected to an oil tube, of a rear axle; d, detecting the left and right steering clutches of the rear axle. According to the arrangement, fault position can be quickly judged, maintenance efficiency is improved, fit precision of all parts is guaranteed, and service life is prolonged.
Description
Technical field
The present invention relates to dozer and turn to fault detection method, belong to technical field of engineering machinery.
Background technology
Dozer is Modern Construction and the common apparatus in production, to the maintenance of each building block, ripe in today that technology is growing.The key of maintenance judges trouble location, took equipment that may be relevant with fault often apart in the past, and checked one by one during maintenance.This not only have impact on overhaul efficiency, the more important thing is, the dismounting repeatedly of mechanical part, affects its quality of fit and tenure of use.
If there is a set of detection method, the possible position occurred according to fault and the difficulty or ease of maintenance, progressively carry out by detecting step, if certain step eliminates fault, then need not carry out the maintenance of following steps, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide dozer and turn to fault detection method, progressively carry out by this invention detecting step, not only can judge trouble location fast, improve overhaul efficiency, and the quality of fit of each parts can be ensured, improve tenure of use.
For achieving the above object, the present invention is realized by following technological means:
Dozer turns to fault detection method, it is characterized in that: comprise the following steps:
A) steering clutch hydraulic system oil pressure is detected;
B) steering pump and switching valve is detected;
C) O-ring seals on the connected pipes of back axle left and right is detected;
D) back axle left and right side steering clutch is detected.
Further:
Described dozer turns to fault detection method, it is characterized in that: described step a) comprises, and as steering clutch Hydraulic System Oil positive pressure is normal, then proceeds to step c); As abnormal in steering clutch hydraulic system oil pressure, then proceed to step b).
Described dozer turns to fault detection method, it is characterized in that: described step b) comprise, as steering pump and switching valve oil pressure are normal, then proceed to step c); As steering pump and switching valve oil pressure abnormal, repair and make oil pressure recover normal.
Described dozer turns to fault detection method, it is characterized in that: described step c) comprise, as O-ring seals damages, change; As O-ring seals is intact, enter step d).
Described dozer turns to fault detection method, it is characterized in that: described steps d) comprising:
D1) back axle left and right side steering clutch is disassembled;
D2) back axle left and right side steering clutch wheel hub locking nut is detected;
