Permanent magnet type magnetorheological fluid deceleration strip
The invention discloses a permanent magnet type magnetorheological fluid deceleration strip, belonging to the technical field of intelligent deceleration strips. According to the invention, an upper supporting plate (2) and a cylindrical piston (4) are fixedly connected with the upper part of a rubber shell (1) to form a movable assembly; a sleeve (7), a stand column (9) with a permanent magnet (6), a bottom plate (10) and the bottom of the rubber shell (1) are fixedly connected to form a static assembly; a magnetorheological fluid (5) is sealed between the movable assembly and the static assembly through a sealing ring (8); and automatic resetting is realized through a reset spring (3) after a vehicle passes by. The damping force of the deceleration strip can be automatically adjusted according to the running speed of a vehicle, hindrance to a low-speed vehicle is small, and hindrance to a high-speed vehicle is obvious; a permanent magnet excitation mode is adopted, an external powersupply and a control module are not needed, a structure is simple, and reliability is high; grooves do not need to be dug in a road surface in the installation process of the deceleration strip, so damage to the road surface is small, and use and maintenance are convenient; and the cylindrical piston of a V-shaped nozzle structure is adopted, so damping force changes gently, and when a vehicle passes at a low speed, the descending height of the deceleration strip is controllable and passing experience is better.
本发明公开了一种永磁式磁流变液减速带，属于智能减速带技术领域。上支撑板（2）、筒式活塞（4）与橡胶外壳（1）的上部固定连接，组成可移动组件；套筒（7）、带有永磁铁（6）的立柱（9）、底板（10）与橡胶外壳（1）的底部固定连接，组成静止组件，磁流变液（5）通过密封圈（8）密封在移动组件和静止组件之间，车辆通过后依靠复位弹簧（3）自动复位。本发明能够根据车辆行驶速度大小，自动调节减速带的阻尼力，对低速车辆阻碍较小，对高速车辆阻碍明显；采用永磁铁励磁方式，无需外加电源和控制模块，结构简单、可靠性高；安装过程无需在路面挖槽，对路面损伤小，使用维护方便；采用V型喷嘴结构的筒式活塞，阻尼力变化平缓，当车辆低速通过时，减速带下降高度可控，通过体验更佳。
