In the entire hoist braking system, the "role" of the Motorcycle Trunk is very important. It determines the braking effect of the brake, and the loss of the Motorcycle Trunk is very large, so we are required to buy a motorcycle. When looking for a trunk, be sure to choose a high-quality one. A high-quality Motorcycle Trunk can be seen from its composition, so what are the components of a Motorcycle Trunk?
1.
Vehicle Accessories An important component of a Motorcycle Trunk is Vehicle Accessories. Vehicle Accessories are divided into asbestos-containing and asbestos-free. In the early days, asbestos-containing Vehicle Accessories were used. Later, it was discovered that asbestos polluted the environment, so the use was abandoned. Nowadays, asbestos-free Vehicle Accessories are basically used. Motorcycle Trunk are roughly divided into metal sheets, semi-metal sheets and non-metal sheets. Metal sheets are made of steel fibers as the main Vehicle Accessories, resin as the structural material, mixed with other things and then fired; semi-metal sheets use graphite, mica, etc. to replace part of the steel fibers, and copper fibers or copper particles are also used; no metal sheets It contains no or only a small amount of metal components and other materials such as ceramic fibers are used as main Vehicle Accessories.
2. Thermal insulation layer
During the braking process, due to the high-speed friction between the Motorcycle Trunk and the brake disc, a large amount of heat is generated instantly. If the heat is directly transferred to the metal back plate of the Motorcycle Trunk, it will cause the brake cylinder to overheat, causing serious problems. This may cause air lock in the brake fluid. Therefore, there is a layer of insulation between the Vehicle Accessories and the metal back panel. The heat insulation layer needs to be resistant to high temperature and high pressure to effectively isolate the braking temperature and maintain a stable braking distance.
3. Adhesive materials
Adhesive materials are also known as structural materials. The adhesive material mostly uses resin. The function of the Motorcycle Trunk is to allow the fibers inside to "stand up" and cause friction with the brake disc. Generally, resin will decompose or burn when it reaches around 380°C, and the fibers will lose structural support. Therefore, if you want to improve the heat resistance of the Motorcycle Trunk and not be affected at high temperatures, a simple way is to increase the metal content. Metal can allow heat to dissipate faster. However, if too much metal fiber is added, the Motorcycle Trunk will become very hard. When the Motorcycle Trunk is braked, it will easily lead to a decrease in braking performance. Generally, few manufacturers adopt this method. Now adding some other special ingredients to the resin can modify the resin. The modified resin can reach about 430°C. If the temperature is higher, the Motorcycle Trunk with this structure will be "unbearable".
4. Lining board
The lining can also be said to be the back panel, which includes noise reduction linings. The Motorcycle Trunk composed of fixed resin and fiber can be installed on the lifting winch and provide a certain strength to ensure that it will not break due to uneven force when the brake is applied. The function of the noise reduction lining is mainly to reduce the vibration and noise generated by braking and improve the comfort of the winch driver. Some manufacturers or low-quality Motorcycle Trunk often do not make noise-reducing linings, and in order to save costs, the thickness of the linings is often around 1.5mm or thinner, which can easily lead to linings during braking. The board (backboard) is easy to fall off, which has certain hidden dangers.
Requirements for the liner: meet strict durability specifications; ensure safe operation of Vehicle Accessories and brake calipers; powder coating technology for the back plate; environmentally friendly, rust-proof, and durable.
