Working principle and maintenance method of Multifunctional Walking Tractor

The clutch is one of the important components of the multi-function walking tractor. It utilizes the friction force generated by the positive pressure of the two parts on the surface to transmit power, and its friction is proportional to the positive pressure and friction coefficient. Size related. Under normal circumstances, different materials have different friction coefficients, the contact surface is smooth and clean, and the friction coefficient is also different; and the greater the positive pressure, the greater the friction.

 

The brake handle of the multi-function walking tractor is placed in the “closed” position. At this time, a certain gap is formed between the release bearing and the release lever. Under the action of six clutch springs, the pressure plate, the driven plate, and the active plate They are pressed tightly together, producing frictional forces that do not slide relative to one another. When the pulley rotates, power is transmitted to the axle shaft through the friction plate to ensure the normal operation of the multifunctional walking tractor.

 

When the multi-function walking tractor clutches and the brake handle is placed at the “off” position, the pulling rod drives the separating claw to rotate at a certain angle. Due to the helical slope between the separating claw and the bearing cover, the separating bearing is forced to move leftwards and separated. The bearing then pushes the release lever. At the same time, the other end of the release lever drives the adjusting screw and the pressure plate to move to the right to further compress the clutch spring. Thus, the pressure plate, the driven plate, and the active plate lose pressure and form a certain gap. At this time, although the pulley also drives the active part to rotate, it cannot be transmitted to the driven part and the power is cut off.

 

When the clutch of the multifunctional walking tractor is in the process of engagement, the handle should be loosened gradually, and the separation should be rapid and thorough so as to avoid the clutch from working in the semi-engaged state. Once the multi-function walking tractor is parked, the shift lever should be placed in the neutral position, and the clutch and brake handle should be placed in the “closed” position so that the release bearing stops rotating and the clutch spring is in the initial state to extend the parts’ service life.

 

In order to ensure the normal operation of the clutch and prolong its service life, it is usually necessary to remove the release bearing after every 300 to 500 hours of operation of the multifunctional walking tractor. Clean it with clean diesel to make it flexible. Put it in a container filled with butter and heat it so that the solution penetrates into the bearing.

 

For the parts of the multi-function walking tractor clutch, such as the separating claws and the bearing cover slopes, they should always be scrubbed cleanly and be pumped or buttered. The small oil hole on the separating claws should be often dripped into the lubrication oil. In addition, when the clutch is assembled, the active piece should be placed between the two follower pieces. The protruding side of the spline nut should face away from the active piece.
