Abstract
The utility model relates to a compression type road surface speed limiting device for a motor vehicle, which comprises a road surface speed reducing ridge and a fixed part, wherein a spring is fixed below the speed reducing ridge and positioned in a groove below the road surface; the plane dimension of the groove and the plane dimension of the road surface speed reducing ridge are corresponding in order to cause the speed reducing ridge to freely lift and lower. The stroke distance of the spring is greater than or equal to the height of the speed reducing ridge in order to ensure that the speed reducing ridge lowers to a position basically parallel to the road surface when the spring is forced.
Description
Technical field
The utility model relates to a kind of compressed road motor vehicle speed-limiting device.
Background technology
On some road surface, for the limiting vehicle speed of a motor vehicle, deceleration ridge has been installed by road administration department on the road surface, as road surface in expressway charge stop mouth, office, the school with need automobile slow traveling highway section etc.Because deceleration ridge adopts hard material to make, and specific height is arranged apart from the road surface, therefore, when pressure wheel in the above the time, vehicle will slide forward or backward, under the situation many at vehicle, that front-and-rear vehicle distance is near, is easy to bump against front or back vehicle.When vehicle after wheel is parked in deceleration ridge under the load-carrying situation very nearby, just be easy to during vehicle start transmission system is damaged, when the vehicular circulation amount was very big, because rigid bump, the deceleration ridge life-span also can shorten greatly.
Summary of the invention
In view of the problem that above-mentioned motor vehicle deceleration ridge exists, the purpose of this utility model is that design is a kind of can the limiting vehicle speed of a motor vehicle, does not damage vehicle drive system again, the compressed road motor vehicle speed-limiting device of vehicle before and after the bump that also can not cause sliding.
The utility model is a kind of compressed road motor vehicle speed-limiting device, comprise road surface deceleration ridge and fixture, it is characterized in that deceleration ridge bottom, road surface is fixed with spring, spring is positioned at the groove under the road surface, and groove planar dimension and road surface deceleration ridge planar dimension adapt.
Deceleration ridge drops to the position parallel with the road surface when guaranteeing spring stress, and the spring travel distance should be more than or equal to the deceleration ridge height.
Operating principle of the present utility model is: when the speed of a motor vehicle is fast, impact force that the road surface deceleration ridge is suffered and telescopic spring direction form the right angle, spring is not failure to actuate because being subjected to downward power, the vehicle that does not slow down is implemented damping to slow down, when the speed of a motor vehicle is slow, the vehicle that has slowed down is then almost as though walking upon flat ground, deceleration ridge on the pressure wheel, and spring is because the drive deceleration ridge that is under pressure moves down parallel to the ground.
The utility model utilizes the flexible principle of spring stress, neither can cause vehicle to get off and damage vehicle drive system when starting after wheel is positioned at deceleration ridge at load condition, also avoided sliding the contingency generation of colliding the front and back vehicle on the deceleration ridge before and after the generation owing to vehicle is pressed in, and, because the buffering of spring, make deceleration ridge can avoid repeatedly suffering powerful the impact as far as possible, thereby also prolonged application life greatly.

The specific embodiment
Embodiment 1
As shown in Figure 1, this compressed road motor vehicle speed-limiting device comprises deceleration ridge and fixture, and deceleration ridge 1 bottom is fixed with spring 2, and spring 2 is positioned at the groove 4 under the road surface 3, groove planar dimension and road surface deceleration ridge planar dimension adapt, so that deceleration ridge lifting in groove is not obstructed.
As shown in Figure 2, sink in order to guarantee compressed road motor vehicle speed-limiting device deceleration ridge 1 when being under pressure, with ground 3 basic horizontal, the stroke distances of spring 2 should be more than or equal to the height of deceleration ridge 1.
Claims (2)
1, compressed road motor vehicle speed-limiting device comprises road surface deceleration ridge and fixture, it is characterized in that deceleration ridge bottom, road surface is fixed with spring, and spring is positioned at the groove under the road surface, and groove planar dimension and road surface deceleration ridge planar dimension adapt.
2, compressed road motor vehicle speed-limiting device according to claim 1, the stroke distances that it is characterized in that spring is more than or equal to the deceleration ridge height.
