Power take-off
Power take-off – this is a device by means of which the torque is redirected to working equipment: winches, pumps, compressor units, etc.
The main task of PTO – drive the equipment directly through a box or an intermediate mechanism, which can be a hydraulic pump or cardan shaft. At the same time, this type of fixture – optional checkpoint node.
The main area of use of PTO – trucks (KamAZs and MAZs, etc.), tank trucks, truck cranes, municipal and other special equipment. As a rule, they install it on a transmission or transfer case.
How does PTO work?
By and large, the principle of operation of the PTO can be compared with the operation of a gearbox, only the first is simpler. There is a drive shaft with a firmly fixed gear, and when turned on, it meshes with the driven gear, which is mounted on another shaft. It transmits torque to the working equipment.
In the process of PTO control, the rod moves mechanically thanks to the lever. In the presence of a pneumoelectric system, the mechanism must be equipped with a chamber where air is supplied under pressure. Air presses on the diaphragm, to which the spring is attached, due to which it compresses, moving the stem with the switching fork. The gears engage, the air descends, which helps to straighten the spring. The stem moves back and the gears are connected.
The power take-off can use up to 40% of the engine power. In most models, switching on is carried out when the machine is not moving.
PTO Varieties
Specialists who understand power take-offs distinguish this mechanism by the following parameters:
- gear ratio indicator;
- number of steps;
- placement of shafts and their number;
- the presence of a reverse or its absence;
- view of the control system.
There are also dependent and independent boxes.
- Dependent are activated only when the clutch pedal is depressed, as they are actually combined with the gearbox. This node cannot be used in the process of moving vehicles. However, this version of the box is lightweight and helps save engine power.
- Independent PTOs are capable of fully functioning on a vehicle in motion or at rest with the clutch engaged or disengaged. Such models are perfectly combined with gearboxes of any kind and power plants, for example, in municipal vehicles.
