Brake on a trailer

How to choose the right roofing on the track

One of the most important mechanisms in the braking system of the passenger trailer is the inertial brake of the rolling, which is mounted on the circle. To understand the principle of operation and the essence of this mechanism, we suggest that you get acquainted with it a little more detail.

the structure of the brake is moderately simple, but effective. Due to the high quality of the structure, the unit has a high level of reliability. You can understand the principle of work "in a two words" from the very name - an inertial brake. Located next to the coupling device, it "connects" the car and the trailer. And the effort transmitted from the tractor to the trailer in one way or reverse is used for the operation of the mechanism.

How does it work

At the time of braking the car, the trailer moves further on inertia, rolling on the vehicle, and from the pressure of the brake stem "pressed" inside the housing, activating the mechanism. He also pulls on the brake cables that bake the drum pads. Thus, there is a braking of the trailer. With this mechanism, you reduce the braking route by about 20% compared to the trailer that is not equipped with such a unit.

What is the mechanism

The design of the inertial brake consists of the following parts:

• The body - protects the internal nodes of the mechanism and secures other elements in the right places for their proper functioning. Can be made of cast iron or steel. The first material is stronger and more monolithic, but more vulnerable to shock loads. And the second lighter and more elastic. For light trailers, it is better to choose options with a steel body, whereas for heavy ones you need to give preference to cast iron, although selecting any option you will not make an error;
• A shock absorber - allows you to set the desired resistance in case of pressure. It is due to its presence that smooth braking is carried out;
• the rod is the strongest part of the unit that activates the transmission mechanism by displacement;
• Sliding bushings - provide a smooth and precise stroke. They are made of solid fluoroplast, but may wear out over time;
• A parking brake is a mechanism that allows you to manually fix the trailer from unforeseen moving during parking.He also performs the insurance function as it involves a cable, which in the event of a trailer breaks will stop it, activating it;
• The transmission mechanism is a lever installed in the middle of the axis of the mechanism. With it you can pull the thrust and cables.

The design additionally installed a dust protection corrugation, which is worn on the front of the rod and protects the mechanism from contamination and the damper ring that stores the back sleeve from large wear. Also, most models use an additional spring that helps to build a brake lever and hold it, fixing the position.

This mechanism will provide safety and comfort when driving a car and on the purchase of a trailer brake should not save, because a poor quality mechanism can cause expensive repair, loss of load or worse. Therefore, it is better to buy a brake of rolling from proven manufacturers if you want to protect yourself from unforeseen situations on the road.
