Bulldozer main clutch failure causes

mechanical Highlands dozers in the project operation, due to improper use of some accessories easily damaged bulldozer, bulldozer is one of the main clutch parts easily damaged, let's take a look at if there is a fault should be handled?
Effect of the plate spring Three leaf spring uniformly riveting on the rear plate clutch, whose role is to separate the clutch, so that by the elastic force of the leaf spring to produce the rear plate separation gap. If the rivets loose leaf springs or leaf spring fatigue itself, hydraulic drive system bulldozers will make it stretch reduced, thus affecting the generation gap between the clutch, causing the clutch is not complete. In addition, when the inner tooth after tooth disc hub tight or rust, etc., will also affect the separation plate, causing the clutch is not complete.

Effect of corrosion

If bulldozer parked time in a humid environment for too long, active plate clutch with its inner sleeve easily rust, due to corrosion products (iron oxide) has expanded features, active plate surface rust at both ends of the separation gap clutch reduce or even disappear, Bulldozer with Universal Blade cause clutch is not complete. Active plate bearing corrosion, makes engine power without friction plate and driven directly to the clutch shaft, the clutch can not cut off the power. In addition, due to lack of active plate bearing lubricant and severe erosion, which results to the same as above. Driven disc after disc element if its set of teeth hub rust, then when the clutch is disengaged, cheap track dozer the axial slip resistance will be great and can not produce the separation gap, resulting in clutch is not complete.

power shift hydraulic dozer

When refitted filter, twist the tank switch 3-5 laps and found a small amount of fuel filter inlet pipe outflow, power shift hydraulic dozer but soon the fuel that is shed. After careful observation and repeated comparisons, and finally found the switch does not turn on the fuel tank. The switch is a spherical structure, rotate 90 ° when the oil is turned on, then rotate 90 °, to cut off the oil. The ball did not handle the switch, there is no limit device, only revealing Quartet iron, chinese dozer supplier driver mistakenly switch as a throttle valve switch use, turn the 3-5 laps to enable the ball back to the closed position. Ball rotation process, although a small amount of fuel into the oil, but only the car 1 min, when the line of fuel burned, the machine that is stalling.

Bulldozers winch spill

Rope winch oil leakage phenomenon at a GJT112 bulldozer appeared in construction. Pull the rope was found after all, the hydraulic oil is leaking from the winch at the seat bolts, and when stepped on the gas leak quickly, almost no oil leakage at idle.Preliminary analysis may be caused by loose bolts or gasket is damaged, but after replacing the gasket and tighten the bolt test machine, the fault persists. Further analysis of the hydraulic schematic view, 80Hp small swamp dozer may be due to poor oil return, resulting in greater backpressure. So the return pipe winch to manipulate the valve replaced, and that the inside of the tank by welding the parts back to the oil on a short tube, put the machine back to the original than some thick hose pipe, so that the end is not connected to the return line control valve, and directly connected to the new oil return spool, to reduce the oil return back pressure. Again the test machine, Chinese Earthmover the fault disappears

Dozers maintain an appropriate degree of tension

If the tension is excessive, the guide wheel spring tension acting on the track pin and pin sleeve, pin and pin sleeve outer circle has been subjected to high compressive stress, during operation of pins and bushings produce premature wear, while the guide pulley tensioner spring will also act on the guide shaft and sleeve, with great surface contact stress, which makes the guide wheel set easily ground into a semicircle, swamp crawler bulldozer with blade steadily from easy stretch, and will reduce the mechanical transmission efficiency, waste engine passed wheels and track power.
If the tension is too loose mechanically driven bulldozer, tracked easily from the guide wheels and rollers, and lose track of the correct, so fluctuations in running track, beat, impact, causing abnormal wear of the guide wheel and the idler.

swamp hydraulic crawler dozer

China mechanical Bulldozer generally applicable to strong seasonal, concentrated quantities, poor construction conditions construction environment, the main job for a short distance of 50-100 meters, such as base construction, excavation, land leveling, clearing roots, push set Gravel, etc., and the scraper and crowding mechanical tillage and help shovel and haul various towed working device and other operations.
Dozers is the most widely used as a swamp hydraulic crawler dozer, it is suitable for the following four soil auger when the auger four and four above the soil or permafrost, you must first loosen the soil, common practices straight shovel side shovel, oblique shovel, tillage operations, such as the split.

mechanical Swamp Bulldozer

small crawler bulldozer Adjust the tension of the track, through the injection nozzle to the tensioning cylinder filling butter or butter discharged from the discharge nozzle, the reference standard gap between each model adjusted. When the track steadily stretched to need to be removed from a group of track section, the drive tooth surface and pin sleeve engaging surface will also be abnormal wear, mechanical Swamp Bulldozer it should engage the deterioration in the situation before appropriate treatment, such as the pin and the pin set upside down, replace worn over the pin and pin sets, the replacement of track joint assembly and the like.

bulldozer manufacturers

hydrostatic drive dozers expand the development of product types, both to meet the different conditions of work adaptability, and must maintain maximum parts commonality (or interchangeability) and basic, which for the majority of users maintenance bring great convenience. bulldozer manufacturers mainly by the engine, transmission, equipment, electrical parts, cab and hood and other components. Among them, the mechanical and hydraulic transmission system also includes a torque converter, the coupling assembly, the planetary gear type power transmission, a central transmission, steering clutches and steering brakes, final drives and travel systems.

Mechanism drive Bulldozers

MYW Bulldozer steering brake is wet, belt wrapped, foot operated with hydraulic assistance and stop braking device. Hydraulic assistance steering mechanism is safe, reliable, flexible labor-saving features. After pulling the lever, the steering clutch can transfer from separation to braking gradually, which avoids unusual wear.
Mechanism drive Bulldozers The joint foot brake pedal is a unique design bulldozers, both sides turned to each brake, but also at the same time with only one foot on either side of the steering brake clutch. With piston-type servo valve so that the disengagement and brake for the steering clutch mechanism reasonably compact, and easy maintenance.

crawler tractor dozer

Bulldozer dozer blade means abbreviation is crawler tractor dozer The main working device, mounted on the front, install the form of a fixed slewing bulldozer two.
Use a stationary blade of a bulldozer, which blade is on the way forward installation, called a straight spade or shovel, used in, small dozer. Rotary blade rotatably in a horizontal plane at an angle installation to achieve unloading shovel, general maximum rotational angle of 25 °; can also tilt the blade at an angle in the vertical plane in order to achieve lateral shovel, roll angle is generally 0 ° ~ 9 °, shown in Figure 1-6. Rotary blade to 0 ° rotation angle of installation, can achieve the same straight shovel. Thus, the rotary blade adapted to a wider range of jobs, large and medium-sized bulldozer install more rotary blade.
