Background technology
At present, the moving velocity of vehicle is more and more faster, and the braking distance of automobile is also accordingly more and more longer, and especially when running on expressway, braking distance is long to be easy to cause pernicious traffic accident.Existing braking automobile mainly is to slow down by the friction on wheel and ground, because the wipe contact area on wheel and ground can not unconfined increase, so vehicle brake need to carry out assisted deceleration apart from also very difficult with reducing by a relatively large margin.
The Chinese patent Granted publication number is: CN2925984Y, the day for announcing is: the utility model patent on July 25th, 2007 discloses by trailer-mounted radar, car running computer, Warning light, hand control switch, the auxiliary automotive speed reducer that deceleration top and deceleration parachute release gear form, after trailer-mounted radar is passed to car running computer with measured automobile and the travelling datas such as the distance between the obstacle and relative velocity and is carried out analyzing and processing, if draw the conclusion that can bump with obstacle, then car running computer can start auxiliary automotive speed reducer when reminding the driver by Warning light, open the deceleration top and discharge deceleration parachute, this process also can be controlled by hand control switch by the driver.But speed reduction gearing adopts deceleration parachute to slow down, and failure rate is higher, and the reaction time is longer, and the effect of assisted deceleration is not ideal.
Summary of the invention
The purpose of this utility model is longer for existing vehicle stopping distance when running at high speed, the defective that safety performance is not good and deficiency now provide a kind of simple in structure, and vehicle stopping distance when running at high speed is shorter, safety performance is good, a kind of vehicle supplementary speed reduction means easy to use.
For achieving the above object, technical solution of the present utility model is: a kind of vehicle supplementary speed reduction means, comprise vehicle body, vehicle body is installed on the chassis side rail, the bottom of described chassis side rail is fixed with shackle bracket, shackle bracket is hinged by an end of turning cylinder and pipe link, the other end of pipe link and ground friction assembly are hinged, the middle part of pipe link is hinged by an end of the expansion link on adapter shaft and the cylinder, cylinder is installed on the chassis side rail of shackle bracket rear side, and the admission port of cylinder is connected with source of the gas through electromagnetic valve by tracheae.
Described ground friction assembly is made of stressed plate, rubber friction sheet and attaching parts, and the upper end of stressed plate and the end of pipe link are hinged, and the bottom of stressed plate is equipped with rubber friction sheet by attaching parts.
The control signal input end of described electromagnetic valve is connected with the sensor of brake system.
Described pipe link adopts and makes with flexible spring steel.
Described electromagnetic valve is air-operated solenoid valve.
The beneficial effects of the utility model are:
1, the utility model is equipped with the supplementary speed reduction means by pipe link, cylinder, expansion link and ground friction module composition in the chassis side rail bottom of existing vehicle, promote pipe link so that the ground friction assembly produces larger friction drag with the road surface by control cylinder, for automobile provides auxiliary braking power except having the wheel brake friction force now.
2, the utility model is simple in structure, and the reaction time is short, and it is reliable to slow down, it is longer to efficiently solve existing vehicle braking distance in the process of running at high speed, the defective that safety performance is relatively poor, and the lateral deviation accident that can effectively avoid automobile to blow out when running at high speed and cause have improved the safety performance of driving.
