What is a disc hydraulic brake? The disc hydraulic brake is controlled by hydraulic pressure, and its main components include brake discs, wheel cylinders, brake calipers, oil pipes, etc. The disc brake is characterized by simple structure, convenient adjustment, good high temperature resistance, fast heat dissipation, light weight but stable braking effect. After the cylinder oil pipe joint of the disc hydraulic brake is removed, air will enter the oil pipe and wheel cylinder. After reinstallation, there will be air in the braking system, causing the braking effect to fail. Therefore, after the joint is removed, the air must be discharged before it can be used normally. So how to bleed the disc hydraulic brake? What are the methods? The editor is here to answer everyone's questions one by one:
The method for bleeding the disc hydraulic brake is:
1. Add sufficient hydraulic oil to the main cylinder, grip the brake grip tightly, allow the air to exhaust, and then immediately connect the connector to the wheel cylinder.
2. Firmly grip the handle of the disc electric hydraulic brake to generate oil pressure in the master cylinder, then loosen the bleed screw to release the air.
3. When no more bubbles are generated at the bleed screw, immediately tighten the bleed screw, loosen the brake grip, and allow the master cylinder to return oil.
4. Repeat the second and third steps multiple times until the air is completely discharged. The action during bleeding must be coordinated to avoid operational errors that may cause air to enter the hydraulic system, causing the work to start over. It is also important to note that during the bleeding process, the hydraulic oil should be adjusted to the master cylinder at any time.
1) YZ series motors can be directly started. When starting YZR series motors, the rotor must be connected in series with an additional resistance or reactance to start the current. The average value of the starting current should not exceed twice the rated current of the corresponding working mode.
2) When cleaning and inspecting YZR series motors, open the cover plate of the observation window and the cover of the dust discharge hole, and clean the Slip ring chamber. If there is dust or oil stain on the surface of the Slip ring, the dust and oil stain can be wiped off with a cloth soaked in gasoline, and the vehicle can only be started after the gasoline volatilizes. For YZR motor, the size of brush spark shall be frequently observed during operation, and the wear of brush and Slip ring surface shall be checked. When sparks occur on the brushes during operation, the principle should be identified and addressed.
