YWZ9 series electric hydraulic block brake

The installation dimensions of the electric hydraulic block brake comply with the GB6333-86 standard, and the technical requirements comply with the JB6406-2006 electric hydraulic block brake standard. Main characteristics of hydraulic brakes: The main swing hinge points of hydraulic brakes are equipped with self-lubricating bearings, which have high transmission efficiency and do not require lubrication during use; The main performance is safe and reliable, with smooth braking and high action frequency. The brake has an interlocking equal distance device, which always maintains equal distance between the two pads during use, avoiding the phenomenon of one brake pad floating against the brake wheel due to uneven distance; The brake spring is arranged inside the spring tube and is equipped with a brake torque scale on one side, making adjustment convenient and intuitive; The asbestos free brake pad and brake pad of the brake adopt a plug-in type, which is safe and reliable, and easy and fast to replace. Service conditions for hydraulic brakes: The ambient temperature of the hydraulic brake is -20 ℃~+50 ℃; Power supply: 380V, 50HZ; Relative humidity: should not exceed 90%; There should be no flammable, explosive, or corrosive gases in the surrounding working environment; The altitude of the location of use complies with GB755-2000; Outdoor rain and snow erosion or corrosive gases and media should use anti-corrosion products

Inspection of brake usage process:

a. Inspect each hinge joint to see if there is any wear, and the wear of the pin shaft generally does not exceed 5% of the original diameter,

If there is wear, it will affect the opening of the brake. b. The lever and spring should be updated if cracks are found. c. The surface temperature of the brake disc should not exceed 300 ℃, otherwise it will affect the braking effect. If there are 0.5mm deep cracks on the surface of the brake disc, it should be re polished. d. During the brake braking process, whether the brake spring is released smoothly, whether there is any jamming between the lower seat of the spring and the inner wall of the spring tube, the spring rod and the upper end of the spring tube. e. After the brake is operated for a long time, the hydraulic oil will become turbid, and a new hydraulic oil (DB-25 transformer oil, usually about a year) needs to be replaced. Before replacing the new hydraulic oil, it is necessary to wait for the oil to completely cool before opening the oil filling plug, Otherwise, the hydraulic oil heated during operation may splash and cause injury. Under normal usage conditions, the thruster operates 5 million times under a 60% intermittent working system, requiring major repairs or complete machine replacement. Note: For maintenance of the brake actuator, please refer to the actuator user manual. Please refer to the user manual for the maintenance of the thruster. User Manual

The brake voltage does not meet the requirements, the wiring phase is not checked, and the frequency does not meet the requirements. Mechanical jamming occurs and the company is contacted to maintain the motor heating Temperature rise, forced cooling or higher ambient temperature. Replace with other products suitable for the environment. After identifying the cause, contact the motor and the company if the oil level is insufficient. Add sufficient oil. Mechanical jamming occurs. Contact the company for maintenance. After connecting to the power supply, push the spring to adjust the length. Adjust the spring according to regulations. The spring does not move to the specified value. After oil injection, the push rod is not fully vented and pulled several times. The power pressure is lower than 85% of the guaranteed normal power supply After searching for the cause, contact the motor company for insufficient fuel, add sufficient fuel, internal leakage, and do not contact the company for insufficient maintenance thrust Low oil viscosity repair mechanical resistance and contact the company for maintenance. Under low temperatures, the oil is not used according to regulations. The connecting bolts of the oil are not tightened or the tightening force is tight or the surrounding tightening force is uneven. The sealing gasket is damaged. The motor shaft oil seal is damaged. The sealing component is replaced. The smoothness of the piston rod is damaged. The replacement is damaged. The oil seal at the piston rod is damaged. The replacement is damaged. Excessive oil injection is eliminated. The thruster does not operate. Find the cause Afterwards, contact the company to adjust the length of the spring according to regulations. The spring brake cannot be opened to the specified value. The hinge joint of the spring length is not strong,

1. The brake has good thermal stability. This is because the brake disc has no friction boosting effect on the friction pad, and also because the size of the brake friction pad is not long, and its working surface area is only 12% to 6% of the brake disc area, so the heat dissipation is good

2. The brake water has good stability. Because the unit pressure of the brake pad on the disc is high, it is easy to squeeze out water, and at the same time, it is easy to shake off water under the action of centrifugal force. In addition, the pad has a wiping effect on the disc, so after water is released, it can only be restored to normal after one or two brake applications; The drum brake, on the other hand, requires more than ten brake applications to restore normal braking efficiency.

3. Good braking stability. The braking torque of the disc brake has a linear relationship with the piston thrust and friction coefficient of the brake cylinder. In addition, there is no self increasing effect. Therefore, the braking torque increases slowly during braking. Compared with the drum brake, it can ensure high braking stability.

4. The braking torque is independent of the forward and backward movement of the car.

5. Under the condition of outputting the same braking torque, the mass and size of the disc brake is smaller than that of the drum brake.

6. Disc type friction pads are easier to replace after wear than drum type friction pads, with a simpler structure and easier maintenance.

7. The gap between the brake disc and the friction pad is small (0.05-0.15mm), which shortens the operating time of the oil cylinder piston and makes it possible to increase the force transmission ratio of the brake drive mechanism.

8. The thermal expansion of the brake disc will not cause a loss of brake pedal travel like the thermal expansion of the brake drum, which also simplifies the design of the automatic gap adjustment device.

9. Easy to form a multi loop brake drive system, ensuring good reliability and safety, ensuring that all wheels of the car can brake uniformly and stably at any speed.
