Problems solved by technology
[0003] The existing speed bumps are all fixed structures set on the ground. Both high-speed and low-speed vehicles will have a bumpy feeling when passing the speed bump. The speed bump is easily damaged by various vehicles for a long time. At the same time, there are many chassis on the market. Very low supercar, it is difficult to pass the existing speed bump without damage

The invention discloses a speed related speed hump which comprises a side bay and a lifting groove. An inner tube is fixed to the lower bottom of the lifting groove, a piston is slidingly connected inthe inner tube, a straight rod is fixed to the upper end of the piston, penetrates through the inner tube and is fixedly connected with a speed hump body, and the speed hump body is slidingly connected with the inner wall of the lifting groove. The speed related speed hump has the advantages that a vehicle is driven up to the side bay and moves towards the inner tube, wheels push a scraping plateto slide towards the inner tube, hydraulic oil in the side bay is added into the inner tube through a first pipe fitting, and meanwhile the hydraulic oil in the inner tub also flows into the liftinggroove through a speed limiting ole. When the running speed of the vehicle is higher, the speed of the hydraulic oil entering the inner tube is higher than flowing-out speed, the piston in the inner tube moves up at the moment, the speed hump body upwards rises, and when the vehicle rolls the speed hump body, a speed reducing effect is played on the vehicle.
Description
technical field [0001] The invention relates to the technical field of speed bumps, in particular to a speed-related speed bump. Background technique [0002] Speed bumps are generally set at highway crossings, industrial and mining enterprises, schools, residential quarters, etc., where vehicles need to slow down and where traffic accidents are likely to occur. They are new traffic-specific safety facilities for reducing the speed of motor vehicles and non-motor vehicles. ; [0003] The existing speed bumps are all fixed structures set on the ground. Both high-speed and low-speed vehicles will have a bumpy feeling when passing the speed bump. The speed bump is easily damaged by various vehicles for a long time. At the same time, there are many chassis on the market. Very low super sports car, it is difficult to pass through the existing speed bumps without damage. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the p...
