<p>A brake device and a clutch system comprising the brake device. The brake device comprises a differential planetary gear mechanism (1) and a transmission device, a brake disc (101) and a braking force applying device (100). The differential planetary gear mechanism (1) comprises a first sun gear (15), a first half shaft (11) integrally formed with the first sun gear (15), a second sun gear (16), a second half shaft (12) integrally formed with the second sun gear (16), a plurality of planetary gears (17) simultaneously engaged with the first sun gear (15) and the second sun gear (16), a planetary gear carrier (18) supporting the planetary gears (17), and housing (13) integrally formed with the planetary gear carrier (18). An input shaft (10) of a brake system is connected to the first half shaft (11) and the second half shaft (12) of the differential planetary gear mechanism (1) through a first transmission device (8, 8'), and the housing (13) is connected to the brake disc (101) through a second transmission device (9), the first transmission device (8, 8') being constructed to make the rotating velocities of the first half shaft (11) and the second half shaft (12) of the differential planetary gear mechanism (1) opposite to each other, and the speed ratio be close to 1 but not equal to 1.</p> |
