Abstract
The utility model provides a hydraulic buffering device for a road speed bump. The device consists of a speed bump, a hydraulic tank and a limit spring and is characterized in that a piston (2) is arranged below the speed bump (1); the limit spring (4) is arranged on the upper end of a concrete wall (3); the hydraulic tank (5) is arranged in the wall; a partition plate (7) is arranged in the middle of the hydraulic tank; a piston box (8) is arranged in the middle of the partition plate (7); a hole (10) is arranged on the partition plate on one side of the piston box; a vent hole (11) is arranged on the upper part of the piston box; and the other side of the piston box is provided with an adjusting screw (13). The hydraulic buffering device overcomes the disadvantages that shaking occurs when a vehicle passes through the speed bump, and has the advantages that speed reduction effect is obviously, no shaking occurs, and unnecessary damage of articles in the vehicle caused by shaking can be effectively avoided.
Description
Technical field
The utility model relates to the deceleration driven field, a kind of more precisely device that utilizes hydraulic pressure to come buffering automobile to jolt on deceleration strip.
Background technology
Raising along with people's living standard, high development of social economy, the owning amount of China's automobile is quite big, various vehicles are more and more in the city, traffic pressure is also constantly soaring, and in order to reduce and to prevent traffic accident, traffic control department can't install the traffic lights place at visitors flowrate in the intensive or large unit districts such as school, hospital, the highway section that needs to reduce car speed is provided with deceleration strip, forces the vehicle reduction of speed to be exercised.But this facility also brings a lot of negative effects and potential safety hazard in the performance positive benefit: the driver not only feels uncomfortable owing to jolt when the deceleration strip, and to vehicle performance and load shockproof goods and bring bigger property loss.Deceleration strip has become " obstacle band " or " danger zone ", brings great inconvenience for a lot of drivers.Do not have good deceleration effect, and have potential safety hazard.Making like this slows down and do not jolted usually can not realize simultaneously.
Summary of the invention
The purpose of this utility model is the deficiency of filling up above-mentioned, provide a kind of slow down effect significantly, the road hydraulic pressure deceleration strip buffer that do not jolt.
The purpose of this utility model adopts following technical measures to realize: a kind of deceleration driven hydraulic damping device, form by deceleration strip, hydraulic fluid tank, limit spring.It is characterized in that: under deceleration strip, be shaped on piston, in the concrete wall upper end limit spring is housed, hydraulic fluid tank is housed between wall, hydraulic oil is arranged in the hydraulic fluid tank, dividing plate is housed in the middle of the hydraulic fluid tank, one piston case is arranged in the middle of the dividing plate, deceleration tube is equipped with in the bottom of case, on the piston case one side dividing plate hole is arranged, and a venthole is arranged at piston case top, the piston case opposite side has a set screw hole, and set screw is housed in the hole.
Remarkable result of the present utility model: the deceleration effect significantly, can not jolt can effectively not avoid on the car article because of being shaken the unnecessary loss that causes.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The specific embodiment
Referring to figure, be shaped on piston 21 time at deceleration strip, limit spring 4 be housed, hydraulic fluid tank 5 is housed between wall in concrete wall 3 upper ends, hydraulic oil 6 is arranged in the hydraulic fluid tank, dividing plate 7 is housed in the middle of the hydraulic fluid tank, in the middle of the dividing plate piston case 8 is arranged, deceleration tube 9 is equipped with in the bottom of case, on the piston case one side dividing plate hole 10 is arranged, one venthole 11 is arranged at piston case top, and the piston case opposite side has a set screw hole 12, and set screw 13 is housed in the hole.
