AI Technical Summary
Technical Problem
EMB brake calipers experience increased brake clearance due to friction pad wear during long-term use. Existing compensation methods rely on high-precision or complex sensor structures and cannot effectively achieve overload protection.
Method used
It adopts a two-stage screw drive mechanism and torque limiter. The motor drives the rotating shaft to move the pressure ring and the screw sleeve synchronously axially, so as to achieve fast and accurate gap elimination and wear compensation, and provide overload protection in case of overload.
Benefits of technology
It achieves fast and accurate brake gap compensation, avoids sensor dependence and structural complexity, and protects transmission components under overload conditions, ensuring braking performance and safety.
