Passive adaptive magneto-rheological speed bump

Abstract

The invention discloses a passive self-adaption magnetorheological deceleration strip. The passive self-adaption magnetorheological deceleration strip comprises a gear shaft, a cylinder rack, a deceleration strip, a winding, a stator iron core, a ring magnet, an annular magnetic yoke, a multi-disc magnetorheological brake and a real time electric energy control module, the upper end of the cylinder rack is fixedly connected to the deceleration strip while the lower end thereof is opened with a blind hole, the blind hole is sleeved out the outer surface of the stator iron core, the winding is wound out the outer surface of the stator iron core, the ring magnet and the annular magnetic yoke are stacked in the blind hole at the lower end of the cylinder rack at interval, the lower end of the cylinder rack is connected with a support spring II and a piezoelectric generating set II, the gear shaft is matched with the cylinder rack, the multi-disc magnetorheological brake is mounted on the gear shaft. The passive self-adaption magnetorheological deceleration strip can adjust the rigidity of the deceleration strip at real time and automatically according to the vehicle speed of the vehicle and have no obstruction action to the vehicle at low speed, the comfort is increased, the vehicle and deceleration strip are protected for reducing the speed for the vehicle at high speed for having the reasonable reminding and punitive action.

Description

technical field [0001] The invention relates to a deceleration belt used on roads, in particular to a magneto-rheological deceleration belt with minimal shock, vibration and turbulence to low-speed vehicles, whose stiffness can be automatically adjusted in real time with vehicle speed, and self-powered. Background technique [0002] With the advancement of science and technology, the improvement of human life and the rapid development of road traffic, the total number of vehicles in our country is increasing rapidly every year. The continuous growth of automobile production and sales, on the one hand, drives the development of the national economy, and on the other hand, it also makes the road traffic safety situation in our country more and more severe. The number of traffic accidents and the number of casualties will only increase. Among them, speeding is the number one killer of road traffic accidents. Therefore, laying speed bumps on highway crossings, industrial and mi...
