Users have consistently responded well, And it is exported to Europe, America and the Asia Pacific region with the main engine, with a long service life. DC brakes, wind power brakes, and safety brakes have low energy consumption, and are highly favored. Power outage braking

Low energy consumption, smooth braking, and long service life

Advantages of drum brakes

The drum brake is cheap and in line with traditional design. During the braking process of a four-wheel sedan, due to inertia, the load on the front wheels usually accounts for 70% -80% of the total load of the car. The braking force on the front wheels is greater than that on the rear wheels, and the rear wheels play an auxiliary braking role. Therefore, in order to save costs, car manufacturers adopt a braking method of front disc and rear drum. However, for heavy vehicles, the speed is generally not very high, and the durability of brake shoes is higher than that of disc brakes, so many heavy vehicles still use the four-wheel drum design.

Disadvantages of hydraulic drum brakes

The braking efficiency and heat dissipation of drum brakes are much worse. The braking force stability of drum brakes is poor, and the braking force varies greatly on different road surfaces, making it difficult to control. Due to poor heat dissipation performance, a large amount of heat will accumulate during the braking process. The brake pads and wheel drums are prone to extremely complex deformation under the influence of high temperatures, which can lead to brake decay and vibration, leading to a decrease in braking efficiency. In addition, after using the drum brake for a period of time, it is necessary to regularly adjust the gap between the brake shoes, and even remove the entire brake drum to clean the accumulated brake powder. Mechanical transmission mechanisms can change the mode, direction, or speed of motion provided by power and be purposefully utilized by people. There were many types of transmission mechanisms in ancient China, which were widely used. In addition to the ones mentioned above, such as seismographs, blowers, and so on, they were all products of mechanical transmission mechanisms. In ancient China, transmission mechanisms mainly included gear transmission, rope transmission, and chain transmission.

Gear transmission. It appeared no later than the Western Han Dynasty. The South-pointing chariot and Jili Drum Car in the Western Han Dynasty and the hydraulic astronomical instrument invented by Zhang Heng in the Eastern Han Dynasty all used quite complex gear transmission systems. These gears are only used to transmit motion and do not require high strength. As for the gears used in production, they need to transmit a large amount of power and generally have a high stress and strength requirement. In ancient times, such gears were used for water extraction, grain processing, and other work using animal power, water power, and wind power. For example, on a rollover, a primary gear transmission mechanism must be applied to change the direction and transmission of motion to meet the working requirements of the rollover. Hydraulic oil brakes can be widely used for deceleration or parking braking of mechanical drive devices such as lifting, metallurgy, mining, ports, docks, construction machinery, etc. The products comply with national standards.

The hydraulic oil brake uses an electric hydraulic thruster as the driving device. The thruster is equipped with a DC electromagnet holding device. During the operation of the brake, the thruster motor only completes the brake opening and release process and turns off the thruster motor. The DC electromagnet holding force maintains the brake open state. The DC electromagnet has a low current and a low temperature rise in the thruster, extending its service life; When braking, the electromagnet loses power. As the motor has already been cut off, the hydraulic oil has completely released pressure, and the push rod and piston are no longer damped by the hydraulic oil when lowering and resetting. The hydraulic brake quickly brakes, improving the hook sliding phenomenon. When the ambient temperature is 0-20 ℃, use No. 10 transformer oil; Use No. 20 transformer oil at 20-45 ℃- 25 # transformer oil for 15-0 ℃

The common faults of hydraulic brakes are as follows:

1. The relaxation distance of the brake pedal is incorrect;

2. There is a lack of brake fluid in the brake master cylinder or air enters the brake system (there is elasticity when pressing the brake pedal or uneven feeling when pressing it);

3. The piston cup of the brake master cylinder is swollen, the compensation oil hole of the master cylinder is stained, or the oil level inside the master cylinder is too high, causing the brake to bite;

4. The oil tank inside the brake fine pump is stuck;

5. The piston inside the wheel cylinder is stuck and the leather cup is damaged.
