Document Type and Number:
WIPO Patent Application WO/2024/066568
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electronic brakes. Disclosed are an electronic mechanical brake having an active heat dissipation function, and a commercial vehicle comprising same. The electronic mechanical brake comprises a brake body and a heat dissipation apparatus; the brake body comprises a motor driving apparatus and an ejecting head; the motor driving apparatus comprises a stator assembly, a rotor assembly, and a rotating shaft; the rotor assembly is provided at an inner ring of the stator assembly; the rotating shaft is fixed to an inner ring of the rotor assembly; the ejecting head is in threaded connection to one end of the rotating shaft; the heat dissipation apparatus is provided at the outer side of the stator assembly; the heat dissipation apparatus comprises a gravity heat pipe; the gravity heat pipe is provided at an outer ring of the stator assembly; a heat pipe heat dissipation apparatus is provided above the gravity heat pipe. The commercial vehicle further comprises a vehicle body; wheels are provided with electronic mechanical brakes having the active heat dissipation function; the vehicle body is provided with a vehicle control unit and four brake control units; and the four brake control units are respectively electrically connected to four electronic mechanical brakes having the active heat dissipation function. The present invention can realize a heat dissipation effect on the stator assembly.
