Abstract

The utility model discloses a car braking device which can add to the greatest degree the contacting size between the car and the ground while the car is braking and reduces, in a short time, effectively the inertia force of the car after being driven in a high speed. The device comprises a hydraulic extensible arm, a steel plate, a rubber washboard and a pin roll liftinglug, wherein the hydraulic extensible arm is of general type which can swing up and down; the front end of the arm is connected with a steel plate which is designed according to the bottom space of the car and which is not easy to deform; the hydraulic extensible arm is connected with the steel plate through the pin roll liftinglug and the steel plate is fixed with the rubber washboard through a screw. Since the hydraulic extensible arm can extend or lift, which is aided by the pressure, along with the fact that the rubber washboard has a big contacting size with the ground and thus a big chaffing size is formed, which can reduce to the greatest degree the large inertia force after being driven in a high speed; thus the car body can be supported safely and the cars can be controlled, and thus a good braking effect of the a car is achieved.

Description

The washboard-type automobile braking device

A kind of automobile braking device that the utility model relates to.

At present, the automobile brake system that car manufacturer both domestic and external is designed all is to make an issue of round the automobile four wheels, by mechanical manual foot-propelled the most at the beginning, develop into air pressure, hydraulic pressure, all can not realize the huge power of being used to that produces when subduing automobile high-speed to greatest extent rapidly exercises.The four cylinder cars logical with a Daepori are example, when automobile so that per hour 80～90 kilometers speed is travelled, sudden stop drag seal generally all about tens meters, in this reaction moment of 0.3～0.6 second, situation is handled proper, will turn danger into safety for these tens meters, have blunt slightly or deal with improperly, will have an accident or facilitated serious accident.Vehicle when high speed driving, the weight of automobile self in addition, at this moment the huge force of inertia that is produced depends merely on the limited area that lands of four wheels, is to eliminate this huge force of inertia fast.General motor tire and ground-surface area of contact only have about 1.5m2, and these four the less ground contact points that distribute are rapidly automobile to be stopped.

Goal of the invention of the present utility model designs a kind of washboard-type automobile braking device at the problems referred to above exactly, and the friction area that contacts with ground when increasing braking automobile to greatest extent quickly and effectively at short notice, is subdued the force of inertia of the back automobile of running at high speed.

The utility model is achieved in that the washboard-type automobile braking device is made up of hydraulically extensible support arm 1, steel plate 2, rubber washboard 3, bearing pin hanger 5.Hydraulically extensible support arm 1 can swing up and down for general-duty hydraulically extensible support arm, the front end of support arm 1 is one can be difficult for deformed steel flat 2 according to car bottom space design-calculated, what rubber washboard 3 adopted is imitative tire tread rubber plate, hydraulically extensible support arm 1 adopts bearing pin hanger 5 to be connected with steel plate 2, and steel plate 2 is fixed with rubber washboard 3 usefulness screws.Hydraulically extensible support arm 1 can use one, also can use two.When adopting one (single hydraulically extensible support arm), must be at car floor medium position welding hanger, hydraulically extensible support arm 1 one ends are connected with the hanger of car floor middle part welding, and the other end connects rubber washboard 3 with the bearing pin hanger; When adopting two (be biliquid pressure stretch contract support arm), must weld hanger on the corresponding position that hydraulically extensible support arm 1 is installed on the automobile axle 7, an end of hydraulically extensible support arm 1 is being connected other end usefulness bearing pin hanger connection rubber washboard 3 with hanger on the automobile axle.When not using the hydraulically extensible support arm, can adopt simple mechanical type, being sling by steel rope is connected support arm washboard on the back axle.Engage handbrake bar during operation, moment, large-area rubber washboard landed, the rear portion be provided with steel rope counter draw to help move back, thereby reach the force of inertia that automobile is subdued in brake rapidly.

The utility model has adopted the design of hydraulically extensible support arm, steel plate, rubber washboard, because the scalable pressure that rises and falls of hydraulically extensible support arm helps and moves back, rubber washboard and contact area of ground are big in addition, and the friction area of formation is big, subdue the huge force of inertia that the back of running at high speed is brought to greatest extent; In express highway travels, the tire blow-out, this brake gear system will help car body more safely, controls vehicle; On ice and snow road and the gravel road that lofty mountains and steep hills, travel, can adjust in advance 1～2 row fixedly rubber plate lead screw towards, effect is fine during braking automobile, anti-skidding effectively sideslip.

Fig. 1 adopts the biliquid pressure stretch support arm structure cutaway view that contracts for the utility model;

Fig. 2 is that the utility model Figure 1A-A is to cutaway view;

Fig. 3 is single hydraulically extensible support arm structure cutaway view for the utility model adopts;

Fig. 4 is that the utility model Fig. 3 B-B is to cutaway view.

By the described elder generation of Fig. 1 rubber washboard 3 usefulness screws are fixed on the steel plate 2, one end of hydraulically extensible support arm 1 is connected with steel plate 2 with bearing pin hanger 5, the hanger that welds on corresponding installation hydraulically extensible support arm 1 position on the other end and the automobile axle 7 connects, also be provided with on the plate face of steel plate 2 and fix laterally anti-and control lacing wire highly, the oil pipe of hydraulically extensible support arm 1 is connected with the back brake oil pipe.When hand brake lever put down, rubber washboard 3 landed.When depressing the foot brake pedal, the braking device of four wheels and washboard-type automobile braking device are worked simultaneously.
