Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a lightweight brake disc. Background Art

[0002] The brake disc looks like a round disc, and it rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes. The existing ones are usually made of alloy materials, which not only have higher strength, but also lower density and lighter weight.

[0003] The general reason for brake disc damage is that the grinding wheel on one side of the brake disc is excessively worn due to excessive friction, which in turn causes the friction of the grinding wheel to decrease. However, other parts except the grinding wheel are basically still usable, but they have to be replaced together with the grinding wheel, which will cause great waste. Utility Model Content
