Abstract

The invention relates to a cylindrical vehicle active suspension electromagnetic actuator, which comprises a primary assembly which is provided with a through hole in a tool shaft shape and a secondary assembly which is arranged inside the through hole of the primary assembly. The primary assembly comprises a winding iron core assembly, wherein the winding iron core assembly comprises an insulating retainer ring, stator punches and a primary coil; the insulating retainer ring has a through cylinder structure; the through hole is formed inside the cylinder structure; a plurality of stator punches are sleeved outside the insulating retainer ring in parallel and are vertical to the axis of the insulating retainer ring; and the primary coil is arranged between two adjacent stator punches and wound outside the insulating retainer ring. The secondary assembly comprises a permanent magnet and a cylindrical piston rod, wherein the permanent magnet coats on side faces of the piston rod and themagnetic pole direction of the permanent magnet is parallel to the axis direction of the piston rod. The cylindrical vehicle active suspension electromagnetic actuator can provide large stroke and electromagnetic force, directly generates the electromagnetic force without intermediate conversion device, has the advantages of high response speed and high control precision, and improves the vehiclesmoothness and control stability.

Description

technical field [0001] The invention belongs to the field of vehicle chassis control, in particular to a cylindrical vehicle active suspension electromagnetic actuator. Background technique [0002] The design of the actuator in the vehicle active suspension system plays a vital role in the effect of active control. Most of the active suspension actuators currently used adopt a hydraulic structure, and some use a rotating motor plus a ball screw. But there are many problems such as complex structure, poor reliability and slow response. The hydraulic structure uses hydraulic pressure as the power source, and it still has the disadvantages of high energy consumption and relatively high cost. For the method of rotating the motor plus a ball screw, such as the patent No. 200310109174.3, the invention named motor energy storage active suspension Patent, or the utility model patent with the patent number 200820058175.8 and the name of the motor energy storage active suspension a...
