Braking system is a very key configuration on the vehicle, judging the performance of a car is good or bad, braking ability is very important. Generally speaking, the common vehicle braking mode is mainly two kinds of gas brake and oil brake, as the car positioning is relatively awkward light truck, both can use the gas brake, can also oil brake, but which one is relatively better?
Gas brake and oil brake structure is different
According to Semi Trailer Manufacturer, the structure of the air brake is relatively complex. It consists of a master brake pump, sub-pump, brake pipeline, air pump, air storage cylinder, high pressure controller, relay valve, and pressure gauge, etc. Therefore, the installation space requirements are relatively high, which is suitable for medium and large vehicles.
In contrast, the structure of the oil brake is much simpler, generally composed of the total pump, pump, oil cup and connecting pipeline, the installation space is relatively small, so it is suitable for small vehicles.
Gas brake and oil brake principle is different
The braking medium used by the air brake is air. After pressure, the brake pad is pushed to work. If the air pressure is insufficient, the braking force can not be obtained.
The braking medium of the oil brake is the special oil for braking. When the brake pedal is stepped down, the piston and seal bowl of the brake pump will be thrust, and then the oil will be transferred to the piston of each brake pump by pushing the rod, so as to promote the brake pad to work.
The parking brake mode of gas brake and oil brake is different
Under the oil brake structure, the parking brake directly applies the braking force to the wheel by pulling up the brake handle.
Under the air brake structure, the parking brake directly acts on the torque on the drive shaft. In order to enhance the braking safety, the parking brake of the general air brake vehicle mostly uses the dead air brake. At ordinary times, the parking brake is in the normal braking state through the strong spring.
The main characteristics of gas brake and oil brake
In comparison, the reaction speed of the air brake is fast, the braking strength is strong, it is not easy to slide in the downhill road condition, the vehicle is fully loaded, and the emergency stop can be realized at high speed, and the emergency brake is not easy to roll over. However, the later maintenance is more complicated, and the wear of the braking system is also more obvious. In some long downhill sections, if the brake pedal is frequently stepped on, it is easy to make the vehicle appear insufficient air pressure leading to brake failure.
The oil brake power output is softer, the driving comfort is better, and the maintenance is relatively convenient. However, the braking reaction speed is slightly slower, the braking force strength is relatively weak, and the oil circuit of the braking system also needs to pay attention to maintenance.
The braking mode of light truck should be combined with the working condition
From the model point of view, the light truck can not be classified as a kind of large truck, also can not be classified as a small vehicle, after all, the weight of 1-3t is placed there, so the gas brake and oil brake, which is more suitable?
If the owner usually transport the weight of the goods is not high, and the requirements of the goods damage is relatively strict, such as fruits and vegetables, cold fresh, flowers, etc., run the route to urban roads, occasionally contact high speed, the choice of oil brake is more appropriate;
If the transport of goods is relatively heavy at ordinary times, such as bagging cement, sand and stone, putty powder and so on, the distribution line is based on the following road, it is best to choose the air brake, to provide sufficient braking force;
If the usual face of uncertain goods, such as moving, building materials, bulk cargo are picked up, driving road conditions including urban roads also include the next road, it is recommended to choose some reliable gas brake, because in the long-term overload transportation conditions, oil brake will soon appear problems, as a direct choice of gas brake, in addition from the domestic hot truck models, or air brake more popular some.
How to maintain gas brake and oil brake at ordinary times
The brake management of the air brake is relatively durable, but we should pay more attention to the wear degree of the brake drum and brake pad, do a good job of regular replacement, and pay attention to regular adjustment, pay attention to whether the air brake pipeline leakage or water phenomenon.
The maintenance of the oil brake is relatively easy, usually check and replace the brake oil regularly, pay attention to the wear and tear of the brake disc and brake pad.
No matter what kind of braking system, the daily car always keep safety in mind, not overload, not speeding, after the vehicle wading, it is necessary to test the braking system on the flat road.
