Jiaozuo brake

Method and steps for adjusting the service brakes:

(1) Fill the brake master cylinder with brake fluid.

(2) When pressing the brake pedal, the brake drum can just reach the point where it cannot be turned by hand.

(3) Remove the brake shoe support pin nut, turn the mark on the brake shoe support pin towards the center of the brake drum, and then turn it in the opposite direction until the support pin cannot be turned with slight hand force. Repeat this process 2-3 times to tighten the nut.

(4) Release the brake pedal and the brake drum should be able to rotate freely by hand. If it cannot be turned, loosen the nut again and gently rotate the shoe support pin in the relaxed direction until the drum can rotate freely, then lock the nut.

(5) Adjust according to the process of adjusting the gap between the brake shoes and the brake drum.

Installation and adjustment of brakes

Brake installation method:

Vertical installation: Loosen nuts 4 and 5 to make the main spring in a free state, loosen nuts 6, rotate screw 7 to open the brake arm, and then fit the brake onto the spring seat of brake wheel adjuster 9.

Horizontal installation: When the brake wheel is already installed between the motor and other components, loosen nuts 4, 5, 6, 7, and 8, turn the screw to remove screws 3 and 7, and lower the brake arm. Install from the side south onto the brake wheel.

Brake adjustment

Adjustment of the working stroke of the thruster

Under the condition of ensuring a small clearance of the brake shoe, the smaller the working stroke of the thruster, the more ideal it is. Therefore, it is necessary to adjust its installation height H1. The adjustment method is to loosen nuts 6 and 8 (as shown in the figure), and rotate screw 7 to ensure that the installation size of H1 meets the requirements of Table 1. After adjustment, tighten nuts 6 and 8.

Adjustment of braking torque

Loosen nut 4, clamp the square head at the tail of the screw, turn nut 5 to make the square spring seat located within the marking line of the spring frame, and tighten nuts 4 and 5 after adjustment.

Adjustment of brake shoe setback

When the brake shoe is opened, adjust bolt 1 to maintain a consistent distance on both sides.

The nut for fixing the brake shoe (see figure) should be appropriately tightened to ensure that the brake shoe and brake wheel can be in place.

Use and Maintenance

Regularly check the working condition of the brakes.

During the inspection, the following items should be emphasized:

Check whether the components of the brake can move normally and whether the adjusting nuts are fastened.

Whether the components of the thruster are normal and whether the hydraulic oil is sufficient. Is there any oil leakage or seepage.
