Abstract
The invention relates to a brake assistor, which comprises: the brake force power uses the rotation or moving wheel to hold the brake force power, and adds force friction sheet to move the force rod, then uses lever theory to increase the brake force power, to brake the machine, vehicle and device. The invention mainly comprises: brake force rod, brake force shoe, and brake force friction sheet, wherein the force rod is connected to the brake cam; the brake force resource lifts the force rod, to compress the upper friction sheet with the rotation or moving wheel and disc, to generate friction force to move the force rod. The invention can be used in plane and vehicle independently or with hydraulic brake.
Description
Technical field
The braking system of " brake booster " genus machine, car, machinery equipment.
Background technique
Vapour pressure is generally adopted in the power source of Motor Vehicle, aircraft and some other machinery equipment brakings, and with afterburning, in case leakage of oil, leakage vapour, valve blockage occur, brake failure much goes out serious accident to hydraulic pressure easily as driving mechanism.A few days ago, I see on TV (CCTV-7 channel): the Chengdu military airfield, and the motor of a fighter quits work for some reason, does not have oil pressure, brake failure, the ground staff has assigned to the pilot and has abandoned the machine order.The danger that the pilot is emitting the fatal crass on runway, has been avoided a serious accident with aircraft landing, if adopt the brake booster braking, can overcome the fault that vapour pressure, hydraulic pressure are made power train.
Summary of the invention
Brake booster is: the braking force source utilizes machine, car, equipment rotation or mobile wheel power, the potential energy braking force source of trying hard to keep not lose, promptly compress mutually by afterburning friction plate and brake drum, dish etc. on the extension lever, produce friction, drive afterburning motion bar position and move.Therefore, extension lever has bigger operating range, and on this basis, the length of lengthening extension lever power arm increases original braking force source, to reach machine, car, the required braking force source of equipment, finishes the purpose that braking is stopped.
The principle that brake booster adopts: stop as the bicycle brake that is travelled, only need two kilograms to finish braking with interior braking force source and stop with hand.If a traveling automobile adopts brake booster to increase the braking force source, just automobile brake can be stopped.
Why brake booster has afterburning effect: different locomotives, equipment have difference and are suitable for the braking of its structure shape.Here lifting automobile is example, pedaling force is two kilograms a power, obtain 100 jin, a traditional unit of weight braking force by the effect of lever principle, this power of 100 jin, a traditional unit of weight is using brake booster not to be used for braking here, but, produce frictional force by power, the potential energy power of braking afterburning friction plate and wheel and move extension lever, obtain bigger operating range, on this basis, the length of increase activity extension lever power arm again, original 100 jin, a traditional unit of weight braking force source is increased, become 150,200,300 jin etc. braking force source.That is to say: two kilograms of pedaling force, become 100 jin, a traditional unit of weight braking force source by leverage, with the brake booster effect be again: one, utilize wheel rotation or mobile power, potential energy power, keeping 100 jin, a traditional unit of weight braking force source does not lose, two, carry out reinforcing again by lever, to reach the required braking force of automobile source.
Description of drawings
Fig. 1 is concrete structure, position and the working principle schematic representation (for example wheel hub of automobile) of brake booster in brake drum.9,10,11 figure numbers are brake booster critical pieces among the figure, and the 12-14 figure number is the brake booster minor components, and parts shown in the 1-8 figure number are parts of exist actually.
Figure a:1, brake drum; 2, friction plate; 3, brake shoe; 4, brake check spring; 5, rest pin; 6, braking bottom board; 7, tire; 8, brake cam; 9, extension lever; 10, afterburning hoof; 11, afterburning friction plate.
Figure b:9, extension lever, 10, afterburning hoof, 11, afterburning friction plate, 12, the assistor return spring, 13, the extension lever sliding-groove, 14, the assistor rest pin.
Working principle: when machine, car need be braked when stopping, manpower is stepped on brake petal, the backguy of sleeve pipe steel wire, extension lever is mentioned, afterburning hoof upper friction plate and brake drum, dish etc. are compressed mutually, (extension lever one end vertically is relatively-stationary to produce frictional force, laterally be movable), extension lever moves under afterburning friction plate effect forward or backward, extension lever and brake cam link, therefore, extension lever pulling brake cam makes the brake shoe upper friction plate stressed, and generation braking force is finished and braked stop machine, car.
Brake booster is along with wheel sense of rotation difference, and the braking extension lever is also finished afterburner process with the wheel sense of rotation, therefore, advances and falls back and can both brake.
Embodiment
Be applicable to the braking of machine, car that travels and the machinery equipment of not travelling.
Application mode: 1, can travel machine, car emergency power do not have oil pressure, automobile not to have under vapour pressure, the oil pressure brakeless situation emergency power as the aircraft of mentioning in the background.2 and usefulness, the vapour pressure of brake booster and machine, car, hydraulic braking is used simultaneously, prevents that vapour, fluid drive mechanism from ging wrong, and avoids the generation of accident.3, the independent use, meeting on the brake booster principle, by experiment, put into practice, technical problem improves to solve and just can independently use brake booster to brake.
Advantage: 1, rapid operation, the driver finishes braking and stops with the pedaling force that is no more than two kilograms.2, simple in structure, easy to manufacture, material is common, no specific (special) requirements, manufacturing equipment are common.3, the pedaling force that needs of brake booster braking is very little, with the transmission of sleeve pipe steel wire backguy as braking, has overcome that vapour pressure, hydraulic pressure, machinery push away, pull bar is made some shortcomings of power train.4, if the independent brake booster that uses is braked, save vapour pressure, hydraulic braking power train, promptly economy is saved the energy again.
Purpose: improve the machine that travels, car and the Security of the machinery equipment of not travelling, avoid the generation of accident, promote economic benefit and social benefit.
Technical problem: different machines, car, equipment have requirements such as different braking force sources, size, installation position, here just do not explain, space on the wheel is said one theory, the act automobile is an example, the distance of reserving the 15-20 centimeter length in brake drum on the face of garden is just enough, I do setting-out and measure, suppose, 10 centimetres of braking extension lever and brake cam total lengths, cam is high 4 centimetres, radius point is in 8 centimeters, and braking extension lever upper end (afterburning friction plate one end) is moved three centimetres, and the cam place just can produce moving of 1.2 centimetres of (two sides) distances.Consult reference materials and learn, the gap between brake strip and the brake drum must not therefore, the 15-20 cm distance be just much of that greater than 6 millimeters (single face, two brakings are 1.2 centimetres altogether).
