Abstract
The utility model discloses a road speed reducer based on the energy-absorbing principle, which comprises a rubber deceleration strip arranged on the pavement of a road in a spanning manner, the rubber deceleration strip is raised on the pavement, a road trough is arranged at the lower part of the rubber deceleration strip, a buffer constituted by combining a plurality of unit hydraulic mechanisms is arranged in the road trough, and the rubber deceleration strip is propped on the buffer. The speed reduction device has the advantages of reasonable structure, convenient use, security, reliability, vibration reduction and noiselessness, etc., not only can the passing vehicles be reminded and forced to run slowly, but also the bumpiness, vibration and noises of vehicles passing the deceleration strip can be lessened, the vehicle driving is secure and reliable with strong comfort and good deceleration effect, and the performance and the security of vehicles are guaranteed.
Description
Technical field
The utility model relates to a kind of road safety deceleration device, specifically is a kind of road vibration damping deceleration device.
Background technology
Reduction apparatus for roadway arches upward a little on the road surface, generally based on the yellow rubber alternate with black, to cause vision attention, make the means of transportation of the vehicle deceleration jogging of process, mainly being arranged on highway road junction, industrial and mineral, enterprise, school and access, residential quarters etc. needs the highway section of vehicle deceleration jogging and the highway section of causing traffic accident easily, and the accident that has reduced each traffic main artery mouth to a great extent takes place.
Yet existing reduction apparatus for roadway also has very important drawback when reduction accident effectively takes place, as: vehicle masses' around the out-of-date noise effect that produces normal life; Control to the vehicular traffic velocity magnitude is not strong, the deceleration poor effect; Vibration damping is limited, and effectiveness in vibration suppression is undesirable, is automobile low-speed is passed through, jolting of bringing also can occur impacting and vibrate, so not only make the passenger produce uncomfortable sensation, vehicle itself is also had damage, long-term accumulation, vehicle damage can become more and more serious, have influence on the life-span of vehicle and parts thereof.
Summary of the invention
The purpose of this utility model provides a kind of jolting when alleviating vehicle by deceleration strip, vibration and noise, can reach the reduction apparatus for roadway of deceleration purpose simultaneously again.
The utility model is to adopt such technical scheme to realize:
A kind of reduction apparatus for roadway based on the energy-absorbing principle comprises across the speed-reducing rubber band that is arranged on the pavement of road, protrudes in the road surface, has the road groove under the described speed-reducing rubber band, is provided with snubber in the groove of road, and described speed-reducing rubber band is supported on the snubber.
Described snubber is made of a plurality of modular buffer in combination, vertically arranges along the speed-reducing rubber band.
Described snubber is the fluid pressure type buffer gear, and this mechanism is inside and outside cylinder structure, and inner casing is a compression cylinder, and outer shell is a cushion dashpot; Piston is arranged in the inner casing, and its piston rod withstands the bottom surface of speed-reducing rubber band, is furnished with back-moving spring under the piston; The bottom of interior casing wall has the through hole of hydraulic medium, communicates with outer shell.
Described piston rod is a group bar structure, has many piston rods arranged side by side and equally distributed.
Be provided with the gutter in the groove of described road.
The beneficial effects of the utility model are:
The utlity model has characteristics such as rational in infrastructure, esy to use, safe and reliable, vibration damping, noise be low, both can remind and force the vehicular traffic Reduced Speed Now, jolting in the time of to alleviate vehicle by deceleration strip again, vibration and noise, vehicle driving safety is reliable, it is comfortable that driver and crew feel, little to the damage of vehicle.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the stereogram of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2: the utility model comprises the deceleration strip 1 that protrudes in pavement of road 2, and and the road groove 9 that is complementary of deceleration strip 1 size, road groove 9 is provided with snubber in the road groove 9 below deceleration strip 1, the speed-reducing rubber band is supported on the snubber.Snubber is made of a plurality of modular buffer in combination, vertically arranges along the speed-reducing rubber band, be arranged in a row, no matter vehicle from road where by deceleration strip 1, always have corresponding snubber to bear its gravity.
Snubber is a hydraulic mechanism, and this mechanism is inside and outside cylinder structure, and inner casing 8 is a compression cylinder, and outer shell 11 is a cushion dashpot; Piston 7 is arranged in the inner casing 8, and its piston rod 3 passes the bottom surface that cylinder cap 5 withstands speed-reducing rubber band 1, is furnished with back-moving spring 10 under the piston 7; The bottom of interior casing wall 12 has the through hole 6 of liquid medium, communicates with outer shell 11.
Its operating principle is: when this deceleration device of automobile process, the gravity of automobile and impact force action are on deceleration strip 1, to bottom offset, piston 7 descends thereupon, spring 10 is compressed, and the liquid medium in the inner casing 8 is extruded, because the volume of liquid is incompressible, liquid medium can only enter outer shell 11 through the through hole on the interior casing wall 6, thereby plays cushioning effect.The damping of buffering effect and through hole 6 is relevant with the elastic force of spring 10, and the elastic force of flow area and spring 10 by appropriate design through hole 6 can obtain the buffering effect that needs.When wheel left deceleration strip 1, under the effect of spring 10, piston 7 resetted, and waits for next vehicle pass-through.
Because suffered power is not vertically downward on the deceleration strip 1, this will influence piston 7 elevating movements, and piston 7 is subjected to worn-out, big with the friction of casing wall, damage easily, for this reason, piston rod 3 is designed bar structure in groups, have many piston rods arranged side by side and equally distributed, the gravity of vehicle is broken down into a plurality of component, thereby changes the direction of power, increases vertical force component, and make piston 7 stressed even, be beneficial to the application life that prolongs hydraulic mechanism.
For preventing ponding in the road groove 9, be provided with gutter 4 in the groove, avoid hydraulic mechanism by aqueous corrosion.
