To explore the technology behind passenger car
90442995 brake pads, we need to analyze the core working principles, materials and structures, system integration and auxiliary technologies, as well as current development trends, etc.:
1. Back plate:
As a "skeleton", it undertakes the pressure transmission function - when the brake pedal is depressed, the brake fluid pushes the caliper piston, and the backing plate evenly transmits the pressure to the friction material to ensure full contact with the brake disc/drum.
2. Insulation layer:
Isolate the high temperature generated by friction and prevent heat from being transmitted to the brake calipers, piston seals and brake oil.
3. Silencer:
Absorb vibration energy during braking, reduce resonance between metal and friction materials, thereby reducing brake noise.
4. Wear sensor:
Mechanical type: The metal alarm piece rubs against the brake disc after wear and produces a harsh "chirp" to remind you to replace it.
Technology trends: changes driven by new energy and intelligence：
Combined with the current status of the industry, the technological development of brake pads is iterating around the three major directions of new energy adaptation, material upgrading, and intelligence:
1. “Hybrid braking” solution for new energy vehicles:
Electric vehicles use regenerative braking, but traditional friction braking still needs to be used as a "backup".
2. Intelligentization: from "passive replacement" to "active early warning":
Electronic wear sensor: monitors the friction material thickness in real time through the chip and links it with the on-board system.
3. Lightweight and environmentally friendly:
Use composite material back plate to reduce the weight of the brake pad.
