The invention discloses an electromagnetic coil, a magnetorheological damper and an automobile. The electromagnetic coil comprises an iron core and an excitation wire. The iron core is sleeved outside the sliding end, and a wire slot is annularly formed in the peripheral side of the iron core; the excitation wire is wound in the wire slot to form an excitation coil, and the cross section of the excitation wire is in a flat geometric shape; the magnetorheological damper comprises the electromagnetic coil and is applied to an automobile. According to the scheme, after the excitation wires are wound into the excitation coil, the gaps between the wires of each turn and the gaps between the wires outside the excitation coil and the slot wall of the wire slot are greatly reduced, under the condition that the space of the wire slot is not changed, the number of turns of the coil can be increased by using the flat excitation wires, and the utilization rate of the space in the wire slot is higher; the effective working length of the electromagnetic coil is larger, the maximum damping force of the magneto-rheological shock absorber can be improved, the electromagnetic efficiency is greatly improved, and large damping force can be generated only through small current.

    本发明公开了一种电磁线圈、磁流变减振器以及汽车,电磁线圈包括铁芯和励磁导线;铁芯套装于滑动端外,铁芯的外周侧环设有线槽;励磁导线绕于线槽内,形成励磁线圈,励磁导线的截面呈扁平几何状;磁流变减振器包括该电磁线圈,并应用于汽车。本发明方案中,在励磁导线缠绕成励磁线圈后,每匝导线之间的空隙,以及励磁线圈外部导线与线槽槽壁之间的空隙大大缩小,在线槽空间不变的情况下,改用扁平形励磁导线可以提升线圈匝数,线槽内空间利用率更高,电磁线圈有效工作长度更大,可提高磁流变减振器的最大阻尼力,电磁效率大大提高,仅需较小的电流即可产生较大的阻尼力。
