Trailer Brake Pads And Supporting Devices
There are many accessories and machinery on the semi-trailer, and it is precisely because of the combination of accessories that the combination of the semi-trailer is formed. For example, trailer brake pads, trailer supports, etc. The semi-trailer support is the supporting device of the trailer. Its function is to support the ground when the tractor is decoupled from the trailer, and bear the load of the front half of the semi-trailer. Turning the crank handle can make the supporting device There are two lifting gears: fast and slow. The high gear is used for no-load and the low gear is used for heavy loads. Let's take a look at the characteristics of trailer brake pads.
1. If the brakes fail when going uphill, you should shift to a medium or low gear in a timely manner and maintain enough power to drive up the slope and park. If you need to park on a half-slope, you should stick to a low gear, tighten the hand brake, and the person accompanying the vehicle should block the wheels with rocks, skids, etc. in time. If there is a backward slip, the rear of the car should face the hillside or a safe side, and turn on the headlights and emergency lights to attract the attention of the vehicles behind and behind.
2. Control the direction according to the road conditions and vehicle speed, shift out of the high speed gear, and at the same time, quickly empty the gas and shift the high speed gear into the low speed gear. In this way, there will be great traction resistance when starting, causing the vehicle speed to decrease rapidly. In addition, when changing to low gear, the handbrake should be used separately, but be careful not to tighten the handbrake or pull it too slowly. If it is pulled too tight, the brake disc will easily "lock", which may damage the transmission parts and lose the braking ability; if it is pulled too slowly, the brake disc will be worn and ablated and the braking effect will be lost.
3. Use the rigid parts of the car such as the bumper and compartment to rub and collide with natural obstacles (rocks, trees or slopes) on the roadside to achieve the purpose of forced parking and escape, and to reduce accident losses as much as possible.
4. When the vehicle is going down a long or steep slope, the brakes should be applied regardless of the situation. It can not only test the braking performance, but also gain time to control the vehicle speed when brake failure is found. It is also called predictive braking. When the downhill brake fails and the vehicle's own mechanism cannot be used to control the speed, the driver should decisively use natural obstacles, such as rocks and trees on the roadside, to create resistance for the vehicle. If you cannot find suitable terrain or objects to use for a while, you can move one side of the car closer to the mountainside in an emergency to use friction to increase resistance and gradually reduce the speed of the vehicle.
