Tip of the week
Heavy vehicle manufacturers at the end of the 20th century and the beginning of the 21st slowly opted for the prospect of braking first and then suspension being managed through an initially simplified and gradually complex air intake-use-recirculation system.
What do air brakes do?
First of all, let's say why a vehicle "without air" does not move. Air brakes work with air. Makes sense so far. However, this does not mean that without air, due to a sudden breakdown, you suddenly have no brakes.
For safety reasons, in recent years, they have reversed their operation. That is, the pads are pressed with force on the tambourines with the use of springs. The air gives opposite movement, in order to release the brakes on the wheel, and let the vehicle move. The driver, pressing the brake pedal, cuts a percentage of the air, so that the spring overcomes the force of the air, and brakes. With damage and loss of air, only the force of the spring remains, so the vehicle remains braked.
The parking brake is not mechanical. It is also air-conditioned. It even sounds every time you tie it and untie it, strongly from outside. It releases significantly more air, and it's audible. It just uses its own separate circuit.
The electric brakes
Electropneumatic brakes (incorrectly referred to as electrobrakes for short) work by pumping a quantity of air into a separate circuit of their own or into the handbrake circuit. Their disadvantage is that if you "lose air" then the vehicle brakes. That is why it is not for permanent braking with the engine off. But only for the course (traffic lights, stops, staying at a certain point with the engine running)
The new technology electric brakes work with magnetic induction, and leave the air circuits intact.
A quick tip
For the good operation of the air system, it is important to regularly empty the air tanks, to clean them of residues that can end up in the valves and cause damage, but also to remove the liquefied air that wears out the parts of the pneumatic system. In the event that you notice the presence of oil in the tanks, the drier and then the vehicle's air conditioner must be inspected immediately.
Spare parts are the most important part of your truck. The selection of spare parts, used or new, genuine or aftermarket/imitation should be based on proper research. Our store has a wide variety of spare parts for trucks (tractors) and trailers (cabins-refrigerators-curtains-parapets-tippers-containers) with a lot of Schmitz Cargobull – Scania – Volvo – DAF
