Abstract
The invention provides a road speed bump with soft vibration, which is formed by combining a plurality of decelerating blocks. The shape of the cross section of each decelerating block in a direction of width and height is similar to a trapezoid; the top of the cross section is a section of straight line, and both sides of the cross section consist of a section of constant acceleration parabola and a section of uniform deceleration parabola; and curvature directions of the constant acceleration parabola and the uniform deceleration parabola on the same side are reverse. The road speed bump with soft vibration is characterized in that low-speed vehicles can pass through the speed bump slowly in a mode of soft vibration to ensure the riding comfort of passengers and the perfect condition of loaded cargos; when passing through the speed bump, high-speed vehicles are subjected to flexible impact, and the size of impact force is proportional to the square of vehicle speed, namely the vehicle speed is higher, the rise and fall of vehicle bodies and vibration impact are greater. Thus the road speed bump ensures the traffic safety of roads, embodies reward and punishment on different vehicles, and simultaneously, eliminates the destruction action of rigid impact generated by the conventional speed bumps on the vehicles and the speed bumps, so that the service life of the vehicles and the speed bumps is prolonged.
Description
Technical field
The present invention relates to the deceleration strip used on a kind of road, specifically a kind of for vehicle and driver and conductor thereof shake soft, ride comfort, less deceleration driven jolts.
Background technology
Along with the raising of expansion, expanding economy and the people's living standard of city size, various vehicles such as car are increasing, and because of the traffic accident of the too fast initiation of the speed of a motor vehicle is risen gradually, Vehicle Speed has become a key factor that influences traffic safety.For this reason, all laid deceleration strip on the road on special road section (as highway road junction, esidential building sub-district fork road, school or plant area doorway etc.), this has reached to a great extent and has forced vehicular traffic to slow down, reduce the purpose that traffic accident takes place.
For a lot of drivers, driving through deceleration strip is a troubling thing.Mainly be because present deceleration driven product category is many, have phenomenons such as unreasonable structure, width be narrow partially, highly higher.Used deceleration strip on the present highway, its both sides majority is plane or arc surface, when vehicle passes through the deceleration strip of projection, no matter speed of a motor vehicle speed all can produce and jump car, the phenomenon of jolting, cause the strenuous vibration of vehicle, the people is felt very ill, also influence driver's traffic safety.If what load on the car is fragile article, the vibrations of jolting of vehicle can cause the article fragmentation.When vehicle passed through deceleration strip fast, the vehicle of beating was bigger to the impact on ground, thereby caused the vibration of surrounding building, caused noise pollution simultaneously.Even the driver has initiatively fallen speed to get off, still to stand the vibrations that deceleration strip causes.The regular bump of wheel and deceleration strip not only causes the loose shift of deceleration strip, also influences the application life of vehicle and deceleration strip.The antagonism of being discord between deceleration driven and driver and conductor, vehicle and the environment has caused people's attention, therefore is necessary from the angle of hommization deceleration driven to be carried out innovative design.
Summary of the invention
The present invention is directed to existing deceleration driven impacts, produces vehicle and jump car, influence deficiency such as driver and conductor's ride comfort sense, provide a kind of to the quick vehicle generation soft impulse that passes through and to the vibrations of slow-moving vehicle and the less deceleration driven that jolts, both remind the driver to reduce the speed of a motor vehicle in advance thereby play, guarantee the effect that passengers inside the car and goods are comfortable, safe again.
The technical solution adopted in the present invention is: constitute a kind of soft deceleration driven that shakes by a plurality of deceleration module units, with parabolic plane or the arc surface that replaces existing deceleration strip both sides.It is characterized in that, the shape of wide, the high direction cross section of deceleration module unit is to trapezoidal similar, the top of cross section is one section horizontal linear, both sides are made up of one section even acceleration parabola and one section even deceleration parabola respectively, and the even acceleration parabola of the same side is opposite with the even parabolical curvature direction of slowing down.

In the such scheme, the material of described deceleration piece can adopt rubber, macromolecular material or metal, or other have the material of higher mechanical strength and impact toughness.
In the such scheme, also comprise being used for the deceleration piece is fixed on bolt on the road surface.
Effect: with present stage widely used deceleration strip compare, characteristics of the present invention are: the vehicle that speed is lower can be mild passes through this deceleration strip, can not produce to jump the car vibrations.And speed faster vehicle will suffer soft impulse when this deceleration strip, square being directly proportional of the size of impact force and the speed of a motor vehicle, the driver and conductor experiences and jolts, and is bigger to the vibration influence of vehicle and institute's cargo.Advantage of the present invention is both to have ensured traffic safety, has improved the comfortableness that slow-moving vehicle is taken again, embodies drawing a clear-cut line between reward and punishment to the different speed of a motor vehicle.Vehicle only is subjected to the limited soft impulse of numerical value during by deceleration strip of the present invention, has eliminated the destruction to vehicle and deceleration strip of rigid shock that existing deceleration strip produces, thereby has prolonged the application life of vehicle and deceleration strip.The present invention has the two-fold advantage of safety and comfortableness, can be used as the regeneration product of traditional deceleration strip.
