Abstract
The utility model relates to a road speed-limiting damping device for vehicles, which is used for limiting the running speed of the vehicles and prompting the vehicles to reduce the speed. The utility model comprises a sliver-shaped crosspiece, wherein a crosspiece seat which is fixed at the bottom of the crosspiece is connected with the crosspiece into a whole; at least two speed reduction tops are arranged under the crosspiece seat; the crosspiece is supported on a piston rod of each of the speed reduction tops. The utility model can generate strong impact vibration to the vehicles which run at the speed higher than prescribed speed and can not generate the impact vibration to the vehicles which run at the speed lower than the prescribed speed.
Description
Technical field
The utility model relates to a kind of Vehicle Speed that is used to limit, and impels the device of vehicle deceleration, particularly is installed in the road vehicle speed-limiting device on the road.
Technical background
The road vehicle speed-limiting device is fixed on some place of road vehicle, is used to impel the vehicle deceleration of fast running, plays the effect of restricted speed.Existing road speed limit device is a strip rigid member, and its bottom is the plane, top bump, and when vehicle crosses from it with certain speed, road speed limit device will cause stronger impact shock to vehicle, make vehicle produce strong jolting.Because existing road speed limit device is for directly being fixed on ground rigid member, it is out-of-date that wheel is pressed from it, road speed limit device can not produce distortion in vertical direction, like this, when vehicle crosses from it with the speed that is lower than regulation, road speed limit device still can cause certain impact shock to vehicle, makes vehicle produce jolting to a certain degree, driver and take advantage of a person riding comfortableness in the vehicle that the speed in accordance with regulations of certainly will influencing is like this travelled.
The utility model content
Technical problem to be solved in the utility model provides a kind of road vehicle damping speed-limiting device, it is fixed in the road, can be to producing stronger impact shock to be higher than the vehicle that fixing speed travels, and can be to not producing impact shock to be lower than the vehicle that fixing speed travels.
Road vehicle damping speed-limiting device described in the utility model, comprise the strip strut rail, be fixed with the strut rail seat and strut rail combines as a whole in rail bottom portion, be provided with at least two tops of slowing down under the strut rail seat, strut rail is bearing on the piston rod that this decelerations pushes up by the strut rail seat.This top of slowing down is damp type oil-air pressure cylinder, and its piston rod is being subjected to external force moment when pressing down fast, and piston rod can not move in cylinder, and when being subjected to external force and pressing down slowly, piston rod will move in cylinder, and after the external force disappearance, piston rod will be from horizontal reset.
Be fixed with fairlead on the strut rail seat, described deceleration top is positioned at fairlead and fairlead matched in clearance, steadily moves to work along the deceleration apical axis with the strut rail that guarantees to combine as a whole with the strut rail seat.
Be set with the compression spring on the top of slowing down, compression spring and deceleration top piston rod together support strut rail and strut rail seat, can be resetted fast after wheel leaves by the strut rail under the pressure wheel with assurance.
This road damping speed-limiting device when mounted must be in the installation place laterally digs along road establishes a groove, road damping speed-limiting device is installed in the groove, and makes its strut rail protrude in ground.When vehicle crossed road damping speed-limiting device to be higher than fixing speed, because the damping action on the top of slowing down, strut rail can not move in groove at once, will cause strong impact shock to vehicle; And when vehicle crosses road damping speed-limiting device to be lower than fixing speed, the same because effect on the top of slowing down, strut rail will move into downwards in the groove, can be to the vehicle vibration that impacts.
The utility model can move the strut rail of road damping speed-limiting device along the direction perpendicular to ground down owing to adopted the top of slowing down earthward, and strut rail can move the impact force that affacts on the strut rail with wheel earthward down relevant, promptly just relevant with the speed of a motor vehicle.So for to be higher than the vehicle that fixing speed is travelled, this road damping speed-limiting device can play the roadblock effect, will be to the vehicle vibration that impacts; And for to be lower than the vehicle that fixing speed is travelled, this road damping speed-limiting device does not play the roadblock effect, will be not can be to the vehicle vibration that impacts, guaranteed that driver and crew in the car take advantage of the comfort level of seat.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 looks schematic diagram for the master of a kind of concrete structure of road vehicle damping speed-limiting device described in the utility model;
Fig. 2 is the cross-sectional schematic of A-A line among Fig. 1;
Fig. 3 is the installment state schematic diagram of this road vehicle damping speed-limiting device in road;
Fig. 4 is the sectional view of B-B line among Fig. 3.
The specific embodiment
As shown in Figure 1 and Figure 2, this road vehicle damping speed-limiting device comprises strip strut rail 1, and strut rail 1 is made by steel plate, and the vacancy is welded with reinforcing rib 7 to increase the rigidity and the intensity of strut rail 1 within it.Be fixed with strut rail seat 2 combines as a whole with strut rail 1 in strut rail 1 bottom, vertically be welded with three fairleads 6 (its quantity is decided according to strut rail length) at strut rail seat 2 upper edge strut rail seats 2, under strut rail seat 2, be provided with three tops 5 of slowing down, the top 5 of slowing down is positioned at fairlead 6 and described fairlead 6 matched in clearance, makes the fairlead 6 can be axially steadily mobile up and down along it with respect to the top 5 of slowing down.On the top 5 of slowing down, be set with compression spring 4, compression spring 4 and deceleration top piston rod 3 together support strut rail 1 and strut rail seat 2, be that strut rail 1 is supported on the deceleration top piston rod 3 by strut rail seat 2, strut rail 1 and strut rail seat 2 also are supported on the compression spring 4 by fairlead 6 simultaneously.
This road damping speed-limiting device when mounted must be in the installation place laterally digs along road establishes a groove, road damping speed-limiting device is placed in the groove, the top of will slowing down 5 is fixed on groove floor, push down strut rail seat 2 with the briquetting 8 that is fixed on the road surface, under the effect of compression spring 4 and briquetting 8, strut rail seat 2 flushes with the road surface, and strut rail 1 protrudes in ground.
When vehicle crossed road damping speed-limiting device to be higher than fixing speed, because the damping action on the top 5 of slowing down, strut rail 1 can not move in groove at once, will cause strong impact shock to vehicle; And when vehicle crosses road damping speed-limiting device to be lower than fixing speed, same because the effect on the top 5 of slowing down, strut rail 1 will move into downwards in the groove, can be to the vehicle vibration that impacts, and after wheel left strut rail 1, under 4 effects of compression spring, strut rail 1 will reset fast, the piston rod 3 on deceleration top 5 makes road damping speed-limiting device recover reset condition also from horizontal reset subsequently.
