Abstract

The utility model relates to a braking synchronous apparatus for a car, which is composed of a synchronous transverse axis, a pullback spring and a friction plate. The braking synchronous apparatus is suitable for various cars and tractors. The novel techniques of the braking synchronous apparatus for a car is characterized in that the braking synchronous apparatus can brake with the original matched braking synchronically and decrease the high speed to zero in seconds to be in a quiescent state. The braking synchronous apparatus can decrease the braking distance by two-thirds compared with that the original braking apparatus regardless of raining, snowing or frozen roadway. The utility model has the advantages of security and reliability.

Description

Braking synchronous apparatus for car

The braking automobile synchronous device.Be applicable to various automobiles, as proud car, utility van, truck, diesel-powered vehicle and various small four-wheel tractor.Be installed in automotive frame lower curtate and former brake synchronous working.Play further shortening braking distance.Reach safe and reliable a kind of novel apparatus, utilize the operating air pressure of automotive interior to make brake power, belong to mechanical transmission fields.

At present, along with the reform and opening-up and the development of building of the four modernizations.The communications and transportation of China is busy day by day.The vehicle flowrate in each city increases day by day with the metropolitan express highway in various countries and builds up in succession.This shows that China just advances with big strides towards the Four Modernizations.At this simultaneously, because the surge of vehicle, the stream of people is crowded.Road is narrow.Some chaufeur is stepped on the gas, and often causes brake failure.Cause traffic accident.Bring immeasurable loss to the country and people.In order to settle the matter once and for all, at first must solve the reliability of braking automobile braking, reduce the traffic story thereby reach.Nineteen ninety the west have on the express highway in a city.More than 20 automobile bumps against together, cause car crash seriously afterwards.Major cause no matter be homemade car, or the car of import, substantially exceeds my desirable brake spacing, so to, behind the car of having stopped, automobile still will travel several meters.This stops apart from several meters, causes the seed of trouble of traffic accident exactly.The root that causes the country and people's lives and properties to damage.For this reason, in order to reduce the loss, ensure the people's life security, I have designed the synchronous device of braking automobile.Below I principle of work once is described and use from now on after important meaning.

At first, when this system did not work, as shown, transverse axis (10), two ends had extension spring (15) synchronously, and extension spring mainly plays reset response.Extension spring one end is fixed on the outer bearing shell (11).The other end is fixed on the automotive frame (17).When this synchronous brake quits work.Garden arc R friction lining and wheel external diameter leave 7 centimetres on outer bearing shell (11) on transverse axis (10) two ends and the bearing shell synchronously.Bottom surface D friction lining (20).Also overhead 8 centimetres.Originally automobile coupling bearing shell in the automobile back wheel in-to-in also breaks away from shell.At this moment automobile does not have the drag friction force, (do not have among the former brake gear figure and draw), when we need brake, the driver is as long as brake the vapour step of stopping gently, at this moment the high pressure gas in the engine cylinder enters high-pressure pipe (19) from A, enter cylinder (6) then, cylinder is fixed on the adapter plate (5), and adapter plate is fixed on again on the automotive frame (17).Because be subjected to the promotion of high pressure draft, cylinder piston connecting rod (7) promotes synchronous transverse axis (10) rapidly.Transverse axis (10) is fixed in the guide plate (4) synchronously, and the guide groove in guide plate (9) is made 45 degree and is tilted to propelling down.Guide plate is by diagonal brace (1) and perpendicular support (2), also have the common burden of crossbeam (3) to be fixed on the automotive frame, two ends, the transverse axis left and right sides connect outer bearing shell (11) synchronously, outer bearing shell R outside friction disc is respectively a1 and a2, outer bearing shell bottom surface D friction lining is respectively b1 and b2, guide groove (9), and usable length is 12 centimetres, when bearing shell (11) is worked outside synchronous transverse axis (10) promotes left and right sides trailing wheel, the rapid and wheel generation forward friction of at this moment outer bearing shell garden arc R a1 of place and a2 friction lining.At this moment operating air pressure is 8kg/cm ²A1 and a2 frictional area are 1/4th of this wheel diameter.This simultaneously since synchronously transverse axis make 45 degree at guide groove and be tilted to down and advance.At this moment, outer bearing shell bottom surface D, D face friction lining is respectively b1 and b2.Friction lining toothing with ground contact surface.Like this, b1 and b2 have just increased reverse friction force at ground friction.Frictional area is four times that wheel contacts with ground, more than two kinds of forwards and oppositely friction, add the interior bearing shell and the hub friction braking of original coupling, these three strands of friction force are worked simultaneously.Can make hot-short reach static in several seconds zero point, thereby further shorten the braking distance, the minimizing accident takes place.

Friction lining on the outer bearing shell (11) has 2 kinds, and the first, garden arc R friction lining.A1 and a2 utilize rubber and fiber to synthesize.Outer bearing shell bottom surface D, b1 and b2, the A type is used for southern general road.Mainly utilize aluminium triangle particle, fiber, rubber to synthesize for three kinds.Type B is used for northern freezing road surface and the road surface of snowing.Be to utilize rubber, fiber and cast iron triangle particle synthetic.A type and Type B friction lining.The bottom surface is toothing all, has good antiskid capability.So, utilize the braking automobile synchronous device, no matter what road surface, this is to rain, snow.Or freezing road surface.Effectively brake percentage is original shortens 2/3rds the distance of stopping, thereby has improved the reliability of safe driving, and as can be seen from the figure, synchronous device only draws half, second half and do not draw.After we shall generally use synchronous brake from now on, will reduce tremendous loss to the country and people, further reduce in express highway and the average highway story that bumps against of getting on the car, the historical tragedy of car crash is no longer drilled, so to, be necessary by the dress synchronous brake.Reducing national wealth suffers a loss less.The development communication.Accelerate building of the four modernizations.
