HOHAN Automatic Brake Clearance Adjusting Arm WG7115540092+017/1 WG4005456212
Installed on the rear axle braking mechanism, it automatically compensates for brake clearance through a combination of worm gear/worm and bracket, ensuring that the clearance between the brake shoes and brake drum remains constant at the optimal value, preventing brake fade, drag, abnormal noise or uneven braking, and improving braking response, safety and durability.
FUNCTION
1. Automatically monitors and compensates for brake clearance in real time. Through a precision worm gear/worm mechanism and mechanical linkage design, it senses changes in the air chamber pushrod stroke during each braking action. When the brake shoes experience increased clearance due to friction and wear, it automatically rotates and adjusts the camshaft position to precisely bring the clearance back to the set value, eliminating the need for manual adjustment and preventing excessive or insufficient clearance due to human error.
2. Maintains consistent and uniform braking under all operating conditions. In complex scenarios such as heavy-load climbing, emergency braking, continuous braking on long downhill slopes, or high-frequency urban driving conditions, it ensures balanced braking force output to the left and right wheels, preventing uneven braking, skidding, or frequent intervention of the ABS system; it also reduces the risk of brake drum/shoe heat fade and maintains stable braking performance at high temperatures.
3. Works closely with the brake chamber and bracket assembly (WG7115540092) to form a complete rear axle braking execution chain: the air chamber pushrod pushes the adjusting arm → the worm gear drives the camshaft to rotate → the brake shoes open and press against the brake drum to achieve braking; after wear compensation, it automatically locks the position to prevent loosening.
