There are two braking methods for concrete self loading mixer: oil brake and air brake. Let's talk about the difference between the air brake and oil brake of concrete self loading mixer.
1. The parking brake of ordinary air brake can only be used when the freight car is stationary, because its braking torque acts on the transmission shaft. If it is used in the driving of small mixer, it is easy to cause serious overload of the transmission shaft and rear axle, and the rotation direction of the left and right wheels may be opposite due to the locking of the differential case, which may cause the freight car to deviate or even turn around when braking.
But the energy storage spring braking is not the case. On the contrary, because the parking braking stroke of the energy storage spring is greater than the service braking stroke, in the case of insufficient service braking force, the energy storage spring can also be used for emergency braking. Therefore, the energy storage spring brake can not only be used as parking brake, but also as emergency brake. Compared with the ordinary brake system, it is more stable in terms of safety and air break.
2. The oil brake has simple structure and small installation space. It only needs the brake master cylinder, slave cylinder, oil cup and connecting pipeline, and does not need other auxiliary equipment; The air brake is much more complicated. In addition to the brake master cylinder, sub cylinder and brake pipeline, there are also air pump, air reservoir, high-pressure controller, relay valve and other components, which need large installation space and complex structure. In addition, in order to ensure safety, the rear brake sub cylinder is now air brake.
3. The conventional brake is that the hand brake locks the transmission shaft, and when the foot brake, the compressed air enters the brake chamber to lock the wheel. In case of mechanical failure of handbrake or transmission shaft, handbrake fails; in case of failure of any part of air pump, pipeline, air reservoir and brake valve, foot brake fails. The air brake can effectively avoid these dangers.
4. There is a strong spring in the brake chamber of the air break brake, which is pushed up by compressed air when driving. The handbrake is to let the air out and let the spring lock the brake. When the air pressure is too low in driving, it will produce braking effect to ensure safety.
The above is the difference between the air brake and the oil brake of the concrete self feeding mixer, I believe you have already understood. If you want to know more about it, please call us.
