Abstract
The invention relates to a manual braking structure for a motor tricycle and a diesel tricycle, in particular to a rear wheel manual service braking structure for the two types of vehicles, which is a manual braking device. On one hand, a braking force of the device is improved, and on the other hand, the manual braking structure is also a braking device matched with a lever-type brake shoe for a tricycle and other vehicles (lever-type brake shoe for short). The invention adopts the technical scheme that mainly, a power arm of the first lever is increased and a moving distance of a power acting point of the first lever is increased, and thus, the characteristic of large opening amplitude of the lever-type brake shoe is met, so that the braking device can be matched with the lever-type brake shoe for use.
Description
Technical field
The present invention relates to motor-tricycle and diesel oil three-wheeled vehicle.Be particularly related to the manpower service brake structure (people are also called rod-pulling type brake equipment manual braking conventionally) of above-mentioned two kinds of vehicles.
Motor-tricycle refers to the various motor-tricycles that motor cycle engine is installed.Wherein, comprise one motor cycle engine is being installed, but car body lighter weight, on transport administration, belonging to the motor-tricycle (for example: motor tricycle ridding by deformed man, the elderly's motor-tricycle etc.) of unpowered vehicle.
Background technology
For a long time, China is every year because the dead and wounded number that traffic accident causes is wandered 310,000 left and right rows, and in rising trend, the traffic accident that relates to three-wheeled vehicle has accounted for again certain proportion, the especially big traffic accident that relates to three-wheeled vehicle having in an accident with regard to more than dead tens people, this except driveship not high, violating the regulations overcrowding beyond, the brake failure of three-wheeled vehicle is also major reason.Therefore, spreading widely in public centres in short: " brake of three-wheeled vehicle is not all right ".
For this reason, let us does a service brake experiment as an example of manual braking's formula motor-tricycle example.Experimental article is: [the complete muscle strength using chaufeur, as only braking energy source, increases the brake equipment of braking force to rod-pulling type motor-tricycle by the principle of lever force-saving, we are called rod-pulling type brake equipment it.Take the motor-tricycle of rod-pulling type service braking device, we are called rod-pulling type motor-tricycle it, and (most motor-tricycles adopts rod-pulling type brake equipment.It is reported, nearly 400～5,000,000 of the year volume of production and marketing of China's rod-pulling type motor-tricycle.Whole electro-tricycles is taked rod-pulling type brake equipment.)]; Experiment purpose is: the service brake effect of inspection rod-pulling type motor-tricycle.In the time that this vehicle empty wagons moving velocity is approximately 30 kilometers per hour, step on fiercely brake pedal, vehicle stops in the front that is approximately 6～8 meters, and the braking mark between wheel and ground is obvious; The approval weight of indicating on the label of this rod-pulling type motor-tricycle is 200 kilograms, when landing two individual weights are respectively about 75 kilograms holding after visitor, be after 150 kilograms of load-carryings, in the time that the speed of a motor vehicle is approximately 30 kilometers per hour, step on fiercely brake pedal, this vehicle forwardly position of about 20 meters stops, and gets off while observing the braking mark that rubs produced between wheel and ground, but at all can not find braking mark, wheel is not by locking.The above-mentioned service brake experiment of repeatedly reforming of the rod-pulling type motor-tricycle of using other various brands instead, result is all roughly the same.
Experimental result: when the service brake of (1) rod-pulling type motor-tricycle empty wagons, braking effect is substantially good, can, rear wheel locking, have braking mark; (2) after the load-carrying of rod-pulling type motor-tricycle when service brake, the obvious variation of braking effect, embracing that rear wheel degree is different is not dead, there is no braking mark; (3) after load-carrying, rear wheel service brake weak effect is the universal phenomenon of rod-pulling type motor-tricycle.
(above-mentioned experiment shows: after people have not done load-carrying, service brake was tested, only in the time that empty wagons service brake is tested, there is braking mark, just think that braking is qualified by mistake, people do not expect after load-carrying that braking effect can variation, the not situation of dead wheel can occur to embrace after not expecting load-carrying).
Since the early 1990s in last century, a large amount of motor-tricycles are developed by two-wheeled motor vehicle, so far there is the history of recent two decades the sixth of the twelve Earthly Branches, it is increasing that the development of three-wheeled vehicle is car body, car body quality is increasing, the situation that manufacturing scale is increasing, but, brake equipment is still almost indiscriminately imitated the rod-pulling type brake equipment of two-wheeled motor vehicle then so far completely, car body quality and braking force are seriously incompatible, and the car body quality day by day increasing displays more and more highlightedly with the hypodynamic contradiction of braking.
[total weight of the rod-pulling type motor-tricycle of finding the sixth of the twelve Earthly Branches has reached 800 kilograms (weight that indicate on label).For example: the model that Mount Everest great river, Chongqing motor-tricycle Co., Ltd produces in August, 2009 is: the motor-tricycle of DJ150ZH-2: conducting oneself with dignity is: 300 kilograms; Load carrying ability is: 500 kilograms; In addition, the motor-tricycle of the model ZS150ZH-2D that Jiangsu Zongshen Motor Tricycle Manufacture Co., Ltd. produces in September, 2009, the total weight indicating on label is 660 kilograms, wherein deadweight: 360 kilograms, load-carrying: 300 kilograms].
How to improve the service brake effect of three-wheeled vehicle? every braking problem that relates to vehicle, all be unable to do without lever problem, and especially most three-wheeled vehicle be unable to do without lever problem especially.
The strong lever that is called that can rotate around attachment point under the effect of power, for example: crow bar, tractor driver Bing etc. draws water.Lever can be straight, can be also curved, " strong " not necessarily rod, general reference have certain length but under the effect of external force indeformable object.Lever has " five elements ":
(1) fulcrum: lever, around the attachment point rotating, is called fulcrum.In the time that lever rotates, fulcrum is relatively-stationary.
(2) power: the power that lever is rotated, is called power.
(3) resistance: hinder the power that lever rotates, be called resistance.
(4) power arm: the vertical distance from fulcrum to dynamic action line, is called power arm.
(5) resistance arm: the vertical distance from fulcrum to drag effect line, is called resistance arm.
Fig. 1 is the schematic diagram of the rear wheel pull-rod type service braking device of motor-tricycle of the prior art.It comprises four levers: be positioned at the each lever on two trailing wheel back-plates, sometimes, we are also called trailing wheel swing arm lever it, is called for short swing arm regulations and parameters, and this swing arm lever is made up of swing arm 5 and camshaft 6; Be positioned near (hereinafter to be referred as chaufeur underfooting) lever chaufeur right crus of diaphragm, sometimes, we are also called foot pedal lever it, and this foot pedal lever forms by stepping on arm 1, treadle 2, axle 11 and pedal 10; Also have a middle lever between three levers recited above, sometimes, we are also called rocker lever it, and this rocker lever is made up of rocking arm 3, rocking bar 4 and axle 11; Between the resistance arm (treadle 2) of the lever of chaufeur underfooting and the power arm (rocking arm 3) of middle lever, be connected with pull bar 20, two resistance arms (rocking bar 4) on middle lever are connected with pull bar 21 and pull bar 22 with the power arm (swing arm 5) of the lever on two trailing wheel back-plates respectively.(trailing wheel back-plate not shown in the figures only illustrates and is positioned at the brake shoe brake cheek 30 of pulling at the bottom of this braking) [sometimes, people are also called rocking arm the swing arm (power arm) being positioned on trailing wheel back-plate; Swing arm 5 is called to Rocker arm 5].
[for the convenience of narrating, sometimes, we also can be called first lever the lever (foot pedal lever) that is positioned at chaufeur underfooting; Middle lever (rocker lever) is called to second lever; Be called rear turbine/lever being positioned at lever (swing arm lever) abbreviation of pulling at the trailing wheel braking end].
Motor-tricycle is developed by two-wheeled motor vehicle, and the rear wheel pull-rod type brake equipment of motor-tricycle is formed by the rear wheel pull-rod type brake equipment transformation of two-wheeled motor vehicle.We compare the rear wheel pull-rod type brake equipment of motor-tricycle with the rear wheel pull-rod type brake equipment of two-wheeled motor vehicle, lever and the rear turbine/lever of finding their chaufeur underfooting are almost identical (lever of their chaufeur underfooting and rear turbine/lever being compared, the proportionate relationship of its shape, size and power arm and resistance arm, all almost identical), their difference is only lever had more in the rear wheel pull-rod type brake equipment of motor-tricycle in the middle of.
Cause wheel to embrace one of them not dead reason and be just middle lever.
For a long time, manufacture the motor-tricycle of enterprise's production of three-wheeled vehicle for domestic more than 200, the structure of nearly all middle lever is in full accord, that is: two resistance arms (rocking bar 4) on middle lever equate, and equate [in motor-tricycle field with the power arm (rocking bar 3) on middle lever, at home in the enterprise of more than 200 manufacture motor-tricycle, the power arm of only finding the middle lever of the motor-tricycle of the Ji Jia enterprise production of listing is below slightly larger than resistance arm, only find a producer (the Feitian five-pointed star board motor-tricycle that the international heavy industry of Zhucheng, Shandong Province Feitian Lei Wo joint-stock company produces) in September, 2009, afterwards, in succession find again several producers (large fortune in Luoyang, north is large sun easily, Luoyang Mount Everest etc.), in electro-tricycle field, the middle lever of whole electro-tricycles all takes two resistance arms (rocking bar 4) to equate, and the structure equating with the power arm (rocking arm 3) on middle lever].
In Fig. 1, if represent the pulling force of pull bar 20 with F; Represent the pulling force of pull bar 21 with M;
Represent the pulling force of pull bar 22 with N; The power arm of lever in the middle of representing with R;
The resistance arm of lever in the middle of representing with r;
(power of middle lever is exactly the pulling force of pull bar 20; The resistance of middle lever is exactly the pulling force of pull bar 21 and the pulling force of pull bar 22);
According to lever principle: lever in the time of balance, kinetic moment=resisting moment; That is: power × power arm=resistance × resistance arm
Specific to lever: F × R=M × r+N × r in the middle of above-mentioned: F × R=r (M+N)
Due to: so R=r: F=M+N
Because two resisting moments equate, so i.e.: M × r=N × r: M=N
Can find out from analysis above: when two resistance arms of middle lever equate, and while equating with the power arm of middle lever, pull bar 21 equates with the pulling force of pull bar 22, and the pulling force of the pulling force of pull bar 21 and pull bar 22 equals respectively the half of the pulling force of pull bar 20, that is:
Can find out from above formula: the pulling force of pull bar 21 equals the half of the pulling force of pull bar 20, the pulling force of pull bar 22 also equals the half of the pulling force of pull bar 20.That is to say, in braking procedure, pulling force is by after middle lever, and the size of pulling force will reduce half, and [strictly speaking, moment has reduced half.When two resistance arms of middle lever equate, and while equating with power arm, pulling force has reduced half.In addition, above-mentioned conclusion also can be confirmed by experiment.Experimental technique is: three pull bars (pull bar 20, pull bar 21 and pull bar 22) are blocked from middle part, connect a spring balance in each truncated position, three pull bars connect three spring balances altogether, when being applied to, we step on while pulling the application force varying in size on 10, read respectively the numerical value of three spring balances, consequently: the pulling force of pull bar 21 equates all the time with the pulling force of pull bar 22; And the pulling force of pull bar 21 equals the half of the pulling force of pull bar 20 all the time; The pulling force of pull bar 22 also equals the half of the pulling force of pull bar 20 all the time.For example: in the time that the reading of the spring balance on pull bar 20 is 10 kilograms, the reading of the spring balance on pull bar 21 is 5 kilograms, and the reading of the spring balance on pull bar 22 is also 5 kilograms; In the time that the reading of the spring balance on pull bar 20 is 30 kilograms, the reading of the spring balance on pull bar 21 is 15 kilograms, and the reading of the spring balance on pull bar 22 is also 15 kilograms; In the time that the reading of the spring balance on pull bar 20 is 60 kilograms, the reading of the spring balance on pull bar 21 is 30 kilograms, and the reading of the spring balance on pull bar 22 is also 30 kilograms etc.].
For a long time, from the lever of the chaufeur underfooting of motor-tricycle with turbine/lever almost identical with rear turbine/lever with the lever of the chaufeur underfooting of two-wheeled motor vehicle, people do not identify two resistance arms are set on middle lever, pulling force is by after middle lever, can cause pulling force to reduce the result of half, thereby do not identify the result that can cause braking force drop by half, and then do not recognize the shorter shortcoming of power arm that the rear wheel pull-rod type brake equipment of motor-tricycle exists lever.
[in recent years, in succession find that the power arm of the middle lever of the motor-tricycle of described several manufacturer production is slightly larger than the situation of resistance arm, but, meanwhile, the power arm of first lever of this motor-tricycle of described several manufacturer production has dwindled again widely, the length of the power arm of first lever of these several producers has been down to 200 millimeter (for a long time, the length of the power arm of the foot pedal lever of motor-tricycle is almost identical with the length of the power arm of the foot pedal lever of two-wheeled motor vehicle, approximately all in 260～280 millimeter or upper and lower, can regard as roughly approximately and be down to 200 left and right from 260～280 millimeter), like this, outwardly, the power arm of lever is slightly larger than resistance arm, but the braking force of whole rear wheel pull-rod type brake equipment does not increase in fact, its object is not for two results that resistance arm produces on middle lever, this has shown that the technical personnel of described several producers does not identify pulling force equally by after middle lever, pulling force will reduce half.(the simultaneously a large amount of reduction of power arm of the amplitude increasing from the power arm of middle lever and foot pedal lever, described several producers do not identify pulling force by after middle lever, and pulling force will reduce half.On the contrary, if the power arm of the foot pedal lever of motor-tricycle remains unchanged, still remain on the length of 260～280 millimeter roughly, and the length of the power arm on middle lever equals the length sum of two resistance arms on this centre lever, can think that people have recognized that pulling force is by after middle lever, pulling force will reduce half.Because only have in the time that the length of the power arm on middle lever equals the length of resistance arm of this centre lever of twice, just can make pulling force pass through, after middle lever, to remain unchanged.If: in the middle of certain, on lever, be provided with a power arm and two resistance arms, the maxim of power arm is 200 millimeters, the maxim of one of them resistance arm is 100 millimeters, the maxim of another resistance arm is also 100 millimeters, so, pulling force is by after this centre lever, and the size of its pulling force remains unchanged)].
Can find out from point folding and experiment above: existing motor-tricycle is with respect to two-wheeled motor vehicle, the car body quality of motor-tricycle has increased, the half but braking force has declined is on the contrary approximately the braking force of two-wheeled motor vehicle
.
People did not both find, did not also expect that pulling force passes through, after middle lever, can change stealthily.People always habitually think to prejudice: the effect of middle lever is only the point of action for changing power, do not change the size of power; And objective fact is: middle lever has not only changed the point of action of power, also there is variation in the size of power stealthily.
So motor-tricycle braking effect is poor, wheel embrace not dead basic reason be in the middle of two resistance arms on lever make the braking force half that declined.
The rear wheel travelling crane braking device of manual braking's formula diesel oil three-wheeled vehicle and the trailing wheel manpower service braking device of above-mentioned motor-tricycle are roughly the same, and they all contain lever in the middle of, and two resistance arms make the braking force half that declined.
For the minimum shortcoming of braking force of above-mentioned two kinds of vehicles (manual braking's formula motor-tricycle and manual braking's formula diesel oil three-wheeled vehicle), the applicant has submitted to respectively name to be called on September 30th, 2010 to State Intellectual Property Office: utility model and the application for a patent for invention of " for the lever brake shoe two of three-wheeled vehicle and other vehicles " (hereinafter to be referred as lever brake shoe), the patent No. and application number are respectively: " 201020557185.3 ", the notification number of " 201010502972.2 " utility model is: " CN201794969 ", the publication number of application for a patent for invention is: " CN102032295A "
Above-mentioned two kinds of vehicles of famine braking force are installed after " lever brake shoe ", have made up the deficiency of the braking force of Manual braking device, have improved braking effect.
The technical scheme of " lever brake shoe " is mainly on the basis of existing technology friction lining to be offset to supporting pin (fulcrum of lever) direction, has namely shortened the resistance arm of brake shoe brake cheek lever.In the situation that power arm is constant, shorten resistance arm, be just equivalent to increase the power arm of brake shoe brake cheek lever.Thereby make " lever brake shoe " become a further laborsaving lever.
Another feature of root Ju lever: the laborsaving merit of not economizing.That is: in the time using laborsaving lever, the power of having economized has but been taken distance, that is to say: the power of having economized has but been taken the mobile distance of dynamic action point (generally: because the friction lining of " lever brake shoe " is offset to supporting pin, so the amplitude of opening of " lever brake shoe " will increase).
" lever brake shoe " is arranged on after two kinds of described manual braking's formula three-wheeled vehicles, the distance that the dynamic action point of each lever moves all will increase, because the power arm of each lever in the trailing wheel manpower service braking device of existing above-mentioned two kinds of vehicles is all less [when mobile distance one timing of dynamic action point, (in other words: when length one timing of circular arc the angle that the lever of the petty action arm of force rotates will be far longer than the angle that large power arm rotates, radius is less, and the angle turning over is larger; Otherwise radius is larger, the angle turning over is just less), when installing after " lever brake shoe ", the angle of rotating due to the lever of the petty action arm of force is too large, can not support the use the sixth of the twelve Earthly Branches with described " lever brake shoe "].So the trailing wheel manpower service braking device of existing above-mentioned two kinds of vehicles can not support the use well with " lever brake shoe ".Want to support the use well with " lever brake shoe ", only have the power arm (reducing the angle of rotation) that increases each lever.Particularly increase the power arm of first lever
More laborsaving the closer to first lever, the distance that lever power point of action in labour-saving moves is just larger.First lever is the most laborsaving, so the distance maximum that the dynamic action point of first lever moves objectively requires the power arm maximum of first lever that is:.Only have the power arm that has increased first lever, could support the use with " lever brake shoe ".
(in the time that brake equipment is one group of lever, first lever refers to external force and puts on the lever of application force.For general brake equipment, first lever refers to the foot pedal lever of chaufeur underfooting.If external force is the service brake of hand operation formula, so, first lever can also be hand operation lever).
List the structure of first lever in the trailing wheel manpower service braking device of motor-tricycle of the prior art below: power arm and resistance arm:
In braking procedure, lever rotates, and the size of power arm, resistance arm changes, and the alleged power arm of the present invention refers to the greatest measure that lever can reach in rotation process, that is: maximum power arm.In like manner, resistance arm refers to the greatest measure that lever can reach in rotation process, that is: maximum resistance arm.Conventionally maximum power arm can be called for short and be called power arm; Maximum resistance arm can be called for short and be called resistance arm.The power arm of first lever refers to axle center (fulcrum) from the lever straight-line distance to the geometric center point of the plate face of brake pedal; The resistance arm of first lever refers to: when lever is in rotation process, and the greatest measure that resistance arm can reach.[or in the time that pull bar and resistance arm are mutual vertical, from the axle center (fulcrum) of lever, to the vertical distance the bar heart line of pull bar, (bar heart line refers to: in the time that pull bar is truncated, truncation surface has a geometric center point, numerous truncation surface has numerous geometric center point, the line that this numerous geometric center point is coupled together, we are called bar heart line this line).]
