The differences of fuel tank truck brakes

Fuel tank truck braking distance is a important safety performance index of a vehicle.Of course, the shorter braking distance is, the more secure vehicle is. Then how to control the braking distance of a vehicle and how to control braking disttance to ensure a safety driving in daily driving are important. Here we will talk about the differences between these two ways of braking. 
1. There is a strong spring in brake air chamber of automatically air-cut brake.Spring will be jacked up by compressed air when driving. The parking brake is to let go of the gas, so that the spring brakes locked. Driving will produce braking effect when the pressure is too low to ensure safety. 
2. Conventional brakes are locked shaft handbrake feet instantly by the compressed air into the brake chamber to lock the wheels. When the hand brake or drive shaft mechanical failure, handbrake malfunction; the pump, piping, air reservoir, brake fault any part of the foot brake failure. And breathe brake can avoid these dangers 
3. Oil brake structure is simple, small installation space, just need to brake master cylinder, wheel cylinders, oil cups and connecting pipe, no other ancillary equipment; air brake is more complicated, in addition to the brake master cylinder, wheel cylinders, brake line, there are a pump (connected by a belt to the engine), gas cylinder, high pressure controller (pressure adjustment, car can reach 8 atmospheres), relay valve and other components, you need to install a large space, more complex structure, and in order to ensure safety, the rear brake cylinder are now expire brakes (additional costs, complex structure). 
4. The reaction of oil brake is slow, soft brakes, small efforts; Air brake reacts fast, brake rough, forceful (high pressure, up to 8 atm). 
So these reasons, the general brake oil, mostly in small and medium sized truck, small size, simple structure, light vehicle itself, does not require much strength, there is a tendency in recent years to the development of the car (load of 10 tons, a number of 19 medium-sized passenger seats or less, are used oil brake). Most air brakes on large trucks, heavy-duty wrecker and silt materials transport vehicles to use car much space, you need the big braking force, the use of long distance, need fast response speed, increased costs are reflected in the trolley The proportion is not much. 
5. Parking brake of ordinary air brake only use in case of a stationary truck. Because it is the braking torque acting on the shaft, if used in a small compression garbage truck with them, can easily cause the drive shaft and the rear severe over load of the bridge, but also may be due to the differential case is locked and rotated left and right wheels of the opposite direction, causing the truck deviation even turn braking. But storage spring brake is not the case, because contrary storage spring parking brake stroke is greater than the service brake stroke, driving under the braking force is insufficient, you can also use the storage spring assisted emergency braking. So not only can be used for storage spring brake parking brake can also be used as an emergency brake. So breathe brake braking system compared with ordinary air brakes, better braking stability and security. 
6. Vehicle parking brake are essentially different, the first one is distributed intermediate disc brake, are human, and the second is the storage spring brake air brake, are dynamic braking. Two kinds of different braking method for fuel tank truck.
