Abstract
The utility model provides a brake emergency system for a slippery road, belonging to the field of an automobile travelling safety technology. The brake emergency system is characterized by comprising a controller, a spray switch, a selector switch, a material level sensor, a brake senor, a vehicle speed sensor, a storage box, a material conveyor, a spreader and an air cylinder, wherein the spray switch, the selector switch, the material level sensor, the brake senor and the vehicle speed sensor are respectively connected with the signal input end of the controller by a signal wire; the output end of the controller is respectively connected with the spreader and the material conveyor by a signal wire; the storage box used for storing a granular fine material is connected with the material conveyor by a pipeline; the material conveyor is connected with the spreader by a pipeline; and the air cylinder used for storing compressed air is respectively connected with the spreader and the material conveyor by a pipeline. The brake emergency system solves the technical problem that the braking force of the truck is sharply lowered when the truck is braked on the slippery road for meeting an emergency, thus improving the safety of the truck which travels under the special road condition.
Description
Affiliated technical field
The utility model belongs to the ride safety of automobile technical field, relates to the wet and slippery road surface of a kind of automobile secondary braking sytem.
Background technology
During emergency braking,, braking force is reduced greatly in some wet and slippery highway sections in the running car because the ground-surface friction coefficient is less; Particularly for the bigger truck of load carrying ability, because inertia is bigger, brake system can not reduce the speed of a motor vehicle effectively; Braking distance is longer, very easily causes traffic accident.Can know from the braking principle of drg, start with, improve the emergency braking performance of automobile, be only effective and actual solution in wet and slippery highway section from the friction coefficient that changes between road surface and the tire.Present technology is to reduce stopping distance through the reasonable distribution braking force mostly, can not effectively solve wet and slippery highway section brake efficiency decline problem.And, then exist the timely and effective cleaning and the road surface pollution problem of viscous liquid temporarily to the method for road surface and tire sprinkling viscous liquid.
Summary of the invention
For solve present automobile in wet and slippery highway section existing the problems referred to above during emergency braking; The utility model provides a kind of mainly is the wet and slippery road surface secondary braking sytem that is directed against truck; Can make truck under this special running environment; Improve braking force effectively, improve running safety.
The utility model solves the technical scheme that its technical matters adopted: comprise controller, spray switch, change-over switch, level sensor, braking sensor, car speed sensor, material storing box, feeder, spreading device and air receiver.Wherein spray switch, change-over switch, level sensor, braking sensor and car speed sensor link to each other with the signal input part of controller through signal wire (SW); The mouth of controller links to each other with feeder with the spreading device respectively through signal wire (SW); Being used for the material storing box of storing granular fines links to each other with feeder through pipeline; Feeder links to each other with the spreading device through pipeline; The air receiver of storing compressed air links to each other with feeder with the spreading device respectively through pipeline.
The utility model has the advantages that: increase the ground-surface friction coefficient through instantaneous method, effectively improve braking force, shorten stopping distance to road surface sprinkling graininess fines.This external system has manually and automatic two kinds of mode of operations, both can in case of emergency manually control sprinkling, also can under the control of control system, realize spraying automatically.It is convenient to be sprayed onto the cleaning of ground-surface graininess fines, pollutes little.
Description of drawings
Fig. 1 is the structure composition frame chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Referring to Fig. 1, system comprises controller, spray switch, change-over switch, level sensor, braking sensor, car speed sensor, material storing box, feeder, spreading device and air receiver.Each lorry is equipped with the identical level sensor of quadruplet, material storing box, feeder and spreading device; Material storing box, feeder and spreading device interconnect through pipeline; And be installed in the below of the relatively large lorry vehicle frame in space, near the wheel place, wherein the spreading device is fixed on the front upper place of wheel.System uses a cover controller, spray switch, change-over switch, braking sensor, car speed sensor and air receiver, accomplishes the control to the quadruplet sprinkler.Feeder and spreading device adopt the miniature pneumatic motor driven, and wherein, it is that former car carries that compressed-air actuated air receiver is provided.Change-over switch has " manually " and " automatically " two positions, and when being positioned at " manually " position, chaufeur is pressed spray switch; Feeder is to spreading device feed; The spreading device is sprayed onto particulate material rapidly on the road surface in corresponding wheel the place ahead under the control of controller, thereby under emergency condition; Instantaneous increase ground-surface friction coefficient shortens stopping distance.When switch was positioned at " automatically " position, chaufeur was stepped on brake pedal, and controller can be according to the information of car speed sensor and braking sensor detection, the work of automatic guidance spreading device.
Level sensor is fixed on the material storing box, is used to detect the quantity of sprinkling material in the corresponding material storing box and pass through the telltale demonstration on the controller, so that chaufeur is in time understood the surplus of sprinkling material and in time added.
