AI Technical Summary

Technical Problem

Existing disc brakes suffer from low efficiency due to their thermoelectric generator units being open to the atmosphere, their wiring harnesses are prone to tangling, their braking energy recovery is insufficient, their braking temperature control strategies are inadequate, and they are susceptible to damage from flying stones, affecting their braking performance and lifespan.

Method used

The disc brake is enclosed in a sealed shell and contains a thermoelectric generator and heat transfer fluid. Combined with a temperature detector and a radiator, the combined use of thermoelectric generator and radiator maximizes the recovery of braking energy and controls the temperature.

Benefits of technology

It improves the working efficiency of the thermoelectric generator unit, avoids wiring harness tangling, enhances braking energy recovery rate, protects the brake from damage by flying stones, and keeps the brake within a reasonable temperature range, ensuring braking performance and lifespan.

Abstract

The application discloses a closed brake device and a temperature control method thereof. The device comprises a disc brake and an energy recovery component. The energy recovery component comprises a closed shell, a heat-conducting liquid and a thermoelectric power generation unit. The disc brake and the heat-conducting liquid are enclosed in the shell. The shell comprises an outer heat-conducting shell and an inner heat-conducting shell which are arranged at intervals. A plurality of thermoelectric power generation units are evenly arranged between the outer heat-conducting shell and the inner heat-conducting shell. The application sets a closed shell outside the disc brake and arranges the thermoelectric power generation unit in the interlayer of the shell, so as to avoid the influence of natural air cooling on the working efficiency of the thermoelectric power generation unit, recover the braking energy of the brake caliper, the friction plate and other parts, maximize the braking energy recovery rate, avoid the entanglement of the wire harness of the thermoelectric power generation unit with the rotation of the brake disc, and avoid the negative influence of foreign matters such as flying stones on the brake, thereby prolonging the service life.
