FIELD: applied mechanics. SUBSTANCE: drive has cylinder 1 filled with magnetorheological liquid 2 accommodating rod 3, mechanical vibration generator 5 and cross variable magnetic field source in form of electromagnet 4. Mechanical vibration generator is hinge-secured on rod 3 outside the cylinder space to change angle of installation. Electromagnet 4 has breaker in supply circuit. Cam 13 is installed on shaft of generator 5 to change its position relative to shaft 12. Cam 13 is installed for engagement with contacts of breaker 15 in electromagnet supply circuit. EFFECT: enlarged operating capabilities. 2 cl, 10 dwgl
