The invention discloses a novel multiple discs brake which comprises a shell (3), a spline flange (1) and a mounting baseboard; the brake provided by the invention is characterized in that a rotor plate (5) is connected with the spline flange (1), a stator plate(4) is connected with the shell (3), the rotor plate (5) and the stator plate (4) are arranged at intervals, and a retracing spring (7) is sleeved on a guide pin (6); the excircle of a piston (8) is mutually connected with the inner hole of an adjusting ring (9), and a pair of screw-driven deputies are formed between the adjusting ring(9) and an outer cone ring (13); an adjusting spring (12) is arranged between the hull (3) and the outer cone ring (13), the outer cone ring (13) and an inner cone ring (14) are mutually matched, a driving braking cavity (18) is formed by a driving pushing disc (15) and the inner hole of the inner cone ring (14)and sealed by a driving oil seal (16); and a parking braking chamber (19) is formed bya parking pushing disc (10) and the excircle of the inner cone ring (14) and sealed by a parking oil seal (17), and the parking pushing disc (10) is provided with a parking spring (11). The brake provided by the invention can increase multigroup friction deputies, and improve a braking torque and has functions of braking in driving and parking process and gap adjusting.
