| 摘要 |
The invention relates to a hydraulic device for braking the wheels of a vehicle, especially for wheel anti-lock and/or anti-slip functions, comprising, between a chamber of a master cylinder and at least one brake motor, a plurality of solenoid valves (36) and a hydraulic pump driven by an electric motor including a rotor (10) arranged between two bearings (12, 14) and enclosed in a cylindrical sleeve (20) made of metallic material, the rotor driving in rotation an eccentric cam (24) imparting an alternating translational movement to radial pistons (26), the delivery outlet of the pump being connected to the solenoid valves (36) via hydraulic slides by way of fluid circulation channels (32, 34). According to the invention, the sleeve (20), in which the rotor is accommodated, is enclosed in a housing (30) made of non-magnetic material. The fluid circulation channels (32, 34) and the solenoid valves (36) extend in the housing. |
