Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake technology, specifically a high load-bearing brake base plate. Background Technology
[0002] The brake backing plate is a crucial component of the brake backing plate assembly. It serves as a supporting part in the automotive brake system, securing the brake shoe assembly to the brake drum, and is the core of the entire vehicle's braking system. To ensure reliable brake operation and reduce dust ingress into the brake system, a dust cover is typically installed on the brake backing plate.
[0003] The core components of the high-load-bearing brake base plate include the base plate body, brake shoe support pin, return spring mounting seat, adjusting arm mounting interface, and reinforcing ribs. Some also include brake caliper mounting holes. In use, first fix the base plate body to the axle or frame according to the positioning holes, then install the brake shoes to the support pin, then install the return spring through the mounting seat, then connect the adjusting arm to the interface, and finally install the brake caliper. After completion, the adjusting arm needs to be adjusted to ensure that the brake clearance is compliant. During braking, the base plate, through the coordinated efforts of all components, bears the pressure and impact of the brake shoes, ensuring braking stability.
[0004] In traditional braking systems, the connecting plate, as a crucial connecting component between the brake shoes and the base plate, often suffers from inherent weaknesses in its design, such as using common materials and lacking targeted structural reinforcement, resulting in insufficient overall strength. One end of the brake shoe is rotatably connected to the connecting plate via a pin. When the vehicle brakes, the brake caliper pushes the brake shoe outward around the pin on the connecting plate, causing the friction pads to come into contact with the brake drum and generate braking force. The reverse friction force of the brake drum against the friction pads is transmitted through the brake shoes to the connecting plate, forming a continuous and significant torsional torque. Since the connection between the connecting plate and the base plate is a stress concentration area, fatigue cracks are easily formed in this area under the repeated action of torsional torque during frequent braking. With increasing use, the cracks continue to expand, eventually causing the connecting plate to break at the connection with the base plate. Damage to the connecting plate not only requires frequent replacement of parts but also causes brake shoe misalignment and brake clearance disorder, thereby affecting the stability of the braking system, significantly shortening the service life of the entire brake, and even creating potential driving safety hazards.
