Introduction of Power take off /PTO on special vehicles

The power take-off is available in many vehicles, such as mixer trucks, wreckers, truck cranes, car carriers, etc. The power take-off can be divided into gearbox power take-off, sandwich power take-off, full power. The power take-off and the power take-off used by the wrecker are the gearbox power take-off. Today we will come together to find out the power take-off of the wrecker.

First understand the type of gearbox power take-off

Gearbox side power output form: It mainly uses the intermediate shaft of the transmission to output the power, and the structure is limited by the reverse gear. This can only reflect 50% of the power, and is generally used in self-unloading, working at height.

Transmission front power output form: It is mainly located in the transmission and clutch parts, it can carry out full power output, and it is mainly used for oil temperature and lubrication control.

The power output form of the rear of the transmission: it can be output through the intermediate shaft or output through the second shaft. Both of these methods can achieve the best power of their engines, mainly used in mixer trucks, pump trucks, forklifts and other vehicles.

The front part of the engine power output form: it is mainly through the crankshaft belt for power output, and is not constrained by time and place during the force taking process.

Let‘s take a look at the role of the gearbox power take-off.

The gearbox power take-off allows a certain gear to obtain the corresponding power, and the electromagnetic valve can be controlled by means of a switch. Its design requirements are relatively simple, and the effect is relatively simple. The methods that appear in the market now include mechanical control, hydraulic control, air control, vacuum source control, and electronic control.

How the gearbox power take-off works

The gearbox power take-off function realizes the self-unloading function by hydraulic means, and realizes the function of increasing and decelerating by one-way or multiple power output or multiple power output, and can be divided into one-axis type by the difference of the total structure. Two-axis, three-axis, with sub-box, single-operated dual-output and dual-operated dual-output, etc., different output forms provide different operating mechanisms.

The one-axis structure is the simplest. The three-axis type mainly performs the force extraction through the two-speed abnormal sound, and the power is increased or decreased with the auxiliary box type. The single-operation double output type is performed through different axes. Coaxial adjustment.

It is very important to use a power take-off on a special vehicle. Usually, the maintenance should be in place to ensure good performance when used.
