The utility model makes full use of the inertial impact force of an automobile body to enhance the friction between the friction blocks and the ground; so, the powerful inertial impact force formed by the emergency brake of the automobile during high-speed driving is effectively controlled and decelerated, and braking performance is improved.
Description
The utility model belongs to the complemental brake system of installing and using on the automobile.
At present, two kinds of independently drgs generally all are housed on the automobile: foot-operated brake and hand brake.In frequent traffic accident as can be seen, the use of foot-operated brake and hand brake, only just can play good deceleration and stopping performance to drive at moderate speed at automobile, when automobile is taked emergency braking suddenly when running at high speed, foot-operated brake and hand brake all can not be in time with automobile safety arrestments in the limited distance scope, the heavy-duty vehicle of especially running at high speed, suddenly behind the emergency braking, wheel and ground will rub and slide tens meters even tens meters and just can stop under powerful effect of inertia, the braking distance that has surpassed regulation this moment already, in the braking, although foot-operated brake has been controlled the rotation of wheel fully, but therefore whole automobile very easily gets into an accident still in preshoot.
The purpose of this utility model is to design the assist brake brake equipment that a kind of automobile is used, the Automobile brake aid that this device is used to slacken the inertia of automobile and shortens emergency stopping distance.
The purpose of this utility model is by realizing by the following technical solutions: Automobile brake aid, it comprises a crossbeam, its two ends are provided with the plate of installing with car chassis both sides crossbeam, be symmetrical arranged two cylinder bodies downwards on the inboard crossbeam of two boards, its inner piston rod can stretch downwards, and the lower end of piston rod is fixed with friction shoe, and an end of friction shoe and brake control lever connects firmly, the other end of brake control lever is limited in the strip hole on the fixed bearing by set bearing pin, and fixed bearing is installed on the automobile axle.
When automobile needs emergency braking in running at high speed, as long as brake pedal is stepped on, qi of chong channel ascending adversely in the cylinder body in the utility model and make the piston rod mobile working, and friction shoe and brake control lever put down, friction shoe is pressed on the road surface tightly, and then force the coast of automobile to stop, thereby play the effect of assist brake.

Embodiment
As shown in Figure 1, the two ends of crossbeam (10) are provided with vertical with the beam body and can the plate (11) that connect be installed with car chassis both sides crossbeam, have mounting hole (111) on the plate (11), overall beam (10) can be fixed between the crossbeam of car chassis both sides by hole (111), the inboard of two boards (11) is crossbeam gusset (12), gusset (12) below is respectively arranged with supporting base (13), supporting base (13) is provided with for the pin-and-hole (131) that cylinder body (20) is installed, simultaneously referring to Fig. 2, above-mentioned supporting base (13) can be symmetrical arranged two cylinder bodies (20), and the pin-and-hole of offering on the projection (23) of cylinder body (20) upper end (231) matches to merge with above-mentioned pin-and-hole (131) and connected by bearing pin.Piston rod (21) in the cylinder body (20) can stretch out downwards when being inflated in cylinder body (20) by tracheae (24), the lower end of piston rod (21) is fixed with friction shoe (30), friction shoe (30) connects firmly with an end of brake control lever (40) again, the other end of brake control lever (40) is limited in the strip hole (51) on the fixed bearing (50) by set bearing pin (60), as shown in Figure 6, fixed bearing (50) is fixedly mounted on the automobile axle.
Referring to Fig. 4, friction shoe (30) selects for use high strength antifriction rubber to make the truncated rectangular pyramids shape, counterbore (32) is arranged for the bottom bar head that holds piston rod (21) on its upper table surface, be provided with the pin-and-hole (33) that level is passed from above-mentioned counterbore (32) between the faceted pebble of both sides, this pin-and-hole (33) is located to align with piston rod (21) lower end pin-and-hole, by bearing pin piston rod (21) is connected with friction shoe (30), the flange (41) that the faceted pebble that retreads is provided with on tapped bore (31) and the brake control lever (40) is matchedly connected.Referring to Fig. 5, see Fig. 1,3,4 in addition, the shaft of piston rod (21) is provided with a block (22), the upper table surface snap of its bottom surface and friction shoe (30).
Because the utility model is moved friction shoe and is realized braking by air pressure control cylinder body, piston rod, therefore, in order to guarantee enough air pressure, an air tank and a brake activation valve for its use is installed specially, the pedal volume I of brake activation valve is directly installed on the side parallel with the foot brake plate.
The formed powerful impulse force of being used to of emergency braking that adjustment is travelled can not only be controlled and slow down to the utility model effectively, and, can also the ramp travel or the rainwater road surface on strengthen the emergency braking performance, especially in the winter time snow or the time icy on road, as long as high-intensity anti-skid stud is set in the bottom surface of friction shoe (30), the serious skidding of appearance in the time of so just can overcoming automobile and on the road surface, brake.Need emergency braking in the galloping, as long as two pedals are together stepped on, it at first is the rotation that foot-operated brake has been controlled wheel, when the wheel that stops operating begins to rub when sliding with ground, piston rod (21) puts down friction shoe (30) and brake control lever (40) under gas pressure, friction shoe (30) compresses on the road surface tightly.Because it is strip hole (51) that fixed bearing (50) is gone up pin-and-hole, therefore, brake control lever (40) is after being subjected to friction shoe (30) and transmitting resistance, move on to the rear end of strip hole (51) rapidly together with bearing pin (60), at this moment, piston rod (21) leans forward under the force of inertia effect of vehicle body, just in time the bottom surface of the triangle block (22) on piston rod (21) shaft is pushed down firmly the upper table surface of friction shoe (30) when leaning forward, so far, the inertia of vehicle body concentrates on the block (22) of piston rod (21) by crossbeam (10) fully, the inertia of vehicle body is stronger, and the pressure that triangle block (22) is implemented friction shoe (30) is bigger.Simultaneously, piston rod (21) still constantly compresses friction shoe (30) under gas pressure, therefore and between the ground has formed powerful friction force.Then, drag friction piece (30) passes to the back axle of automobile by brake control lever (40) and fixed bearing (50) with powerful friction force, forms the resistance that automobile slide advances, and forces the inertia of automobile to weaken, and friction force is bigger, and being used to of automobile is big more a little less than eating up part of.After decontroling the braking accessory pedal, the power that compresses of braking-in-aid unit disappears with being used to dash, and helps the effect of stopping promptly to stop.
The utility model structure straw are simple, be convenient to install, as long as make the braking-in-aid unit of different size according to the size of vehicle, the utility model can be widely used on the various vehicles.
