Oil brakes and air brakes are no strangers to us. There is also a brake system called gas top oil. It was often seen on Japanese trucks years earlier. Gas-capped oil brakes are also called gas-pushing oil brakes and gas-liquid brake systems. At the same time, there are both pneumatic and hydraulic devices. The conventional dynamic brake system includes pneumatic brake system, gas top hydraulic brake system and full hydraulic brake system. The gas top hydraulic brake system is a combination of air pressure and hydraulic pressure. It can also be seen as a brake system in which the air brake and the oil brake are connected in series. Mitsubishi T850 uses a gas-liquid brake system Similar to the air brake, the first half of the gas-liquid system, that is, the same driving force source used in the air pressure system, just added a hydraulic system from behind the brake air chamber (this set of hydraulic system also follows the oil brake system Similar) as a brake actuator. The brake air chamber and the hydraulic master cylinder are connected in series. By converting the air pressure energy into hydraulic energy, the brake fluid is transmitted to each wheel cylinder and the braking effect is generated. Compared to the pure air brake, the brake air chamber in the gas top liquid system has a small volume and is relatively compact in arrangement. In addition, the gas-liquid brake system has these advantages: 1. The short length of the air pressure system can reduce the lag time; 2. The hydraulic wheel cylinder as an actuator is light in weight; 3. When towing the trailer, the trailer can be pneumatically braked or hydraulically braked. According to the experience of the Forum's card friends, the gas-capped oil brakes do have a good braking force, and they respond quickly. They are not as fierce as the braking force of the air brake, but they also have shortcomings. The high temperature of a long downhill slope will degrade the performance of the brake fluid, and the sealing cup of the hydraulic wheel cylinder (pump) will melt or even fall off, causing the brake fluid to leak and flick, causing the brake force to disappear. After all, the quality of this kind of rubber cup is really a big problem. In addition, the long-term maintenance and the use of brake drums are also particularly troublesome. After all, reliability is not as good as a relatively simple pure air brake. â— Postscript: Nowadays, in addition to vehicles that require hydraulic systems such as loaders and dump trucks, it has been difficult to find gas-to-liquid brake systems. In addition, a type of clutch assistance on trucks is often referred to as capping oil. In fact, this claim is inaccurate. The clutch system uses a sub-pump that uses pressure assistance. The principle is different from that of the gas top brake. Next, the author will also introduce this clutch booster pump.
