Lead READ As a construction robot, many people treat the bulldozer as their own friend. However, some problems will occur during the use of the bulldozer.
Today, Peng Dazheng and everyone continue to talk about the problem of the bulldozer walking fault. The fault of the walking system may be slow walking speed, unilateral walking weakness, engine braking while walking, walking card issuing, walking frustration, etc. The problem on the 'legs and legs'. We talked about what should be done when the engine brakes while walking.
Engine brake while walking
Engine brakes are also a common fault on bulldozers. The main reasons for this phenomenon are the following:
01, hydraulic motor reducer failure
The hydraulic motor is a high-speed, low-torque motor that cannot directly drive the bulldozer. Generally, the bulldozer uses the planetary gear set to decelerate the hydraulic motor and increase the torque.
When the reducer fails, the reducer's own resistance is too large, causing the hydraulic motor to load too high, and the hydraulic circuit pressure rises, causing the engine to brake.
02, the track is too tight
The track tension of the bulldozer is adjustable. Through the adjustment of the stroke of the tightening cylinder, when the track is too tight, the resistance of the hydraulic motor is too large, which is easy to cause the brake.
03, winter crawler is frozen
In winter, the temperature in some areas is extremely low. The bulldozer has water and mud on the track after the previous day's work. The water freezes on the next day to freeze the track, causing the hydraulic motor to load too high and the hydraulic circuit pressure to rise. Engine brakes.
