Description
Technical field
The present invention relates to motor-tricycle and electro-tricycle, particularly the trailing wheel manpower service brake of motor-tricycle and electro-tricycle structure (people are called the rod-pulling type brake equipment to the manual braking usually).
Motor-tricycle refers to the various motor-tricycles that motor cycle engine is installed.Wherein, comprise a kind of motor cycle engine that is equipped with, but the car body lighter weight, on transport administration, belonging to the motor-tricycle (for example: disabled person's motor-tricycle, the elderly's motor-tricycle etc.) of unpowered vehicle.
Background technology
For a long time; China arranges about 310,000 because of the dead and wounded number that traffic accident caused and wander every year, and in rising trend, and the traffic accident that relates to three-wheeled vehicle has accounted for certain proportion again; The especially big traffic accident that relates to three-wheeled vehicle that has in accident with regard to more than dead tens people; This is not high except driveship, violating the regulations overcrowding beyond, the brake failure of three-wheeled vehicle also is a major reason.Therefore, spreading widely in public centres in short: " brake of three-wheeled vehicle is not all right ".
For this reason, one of let us is done a service brake experiment.Experimental article is: the rod-pulling type motor-tricycle [fully with the muscle strength of chaufeur as only braking energy source, increase the brake equipment of braking force through the principle of lever force-saving, we are called the rod-pulling type brake equipment to it.Take the motor-tricycle of rod-pulling type service brake device, we are called the rod-pulling type motor-tricycle to it, and (most motor-tricycles adopts the 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 the rod-pulling type brake equipment.)]; Experiment purpose is: the service brake effect of check rod-pulling type motor-tricycle.When this vehicle empty wagons moving velocity per hour is approximately 30 kilometers, step on brake pedal fiercely, vehicle stops in the place ahead that is approximately 6～8 meters, and the braking mark between wheel and the 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 respectively be about 75 kilograms hold the visitor after, i.e. after 150 kilograms of the load-carryings; When the speed of a motor vehicle per hour is approximately 30 kilometers; Stepping on brake pedal fiercely, stops in the about forwardly 20 meters position of this vehicle, gets off and observes when rubbing the braking mark that is produced between wheel and the ground; But at all can not find braking mark, promptly wheel is not by locking.The above-mentioned service brake experiment of reforming repeatedly of the rod-pulling type motor-tricycle of using other various brands instead, the result is all roughly the same.
Experimental result: during the service brake of (1) rod-pulling type motor-tricycle empty wagons, braking effect is good basically, can braking mark be arranged to the rear wheel locking; (2) after the load-carrying of rod-pulling type motor-tricycle during service brake, the obvious variation of braking effect, embracing that the rear wheel degree is different is not dead, does not have braking mark; (3) rear wheel service brake weak effect is the universal phenomenon of rod-pulling type motor-tricycle after the load-carrying.
(above-mentioned experiment shows: service brake was not tested after people had done load-carrying; Only be when the empty wagons service brake is tested, braking mark is arranged, just think that braking is qualified by mistake; People do not reckon with after the load-carrying that braking effect can variation, the not situation of dead wheel can take place to embrace after not reckoning with load-carrying).
Since the early 1990s in last century; A large amount of motor-tricycles is developed by two-wheeled motor vehicle, the sixth of the twelve Earthly Branches the history of recent two decades has been arranged so far, and it is increasing that the development of three-wheeled vehicle is car body; The car body quality is increasing; The situation that manufacturing scale is increasing, however brake equipment is still almost completely indiscriminately imitated the rod-pulling type brake equipment of two-wheeled motor vehicle then so far; Car body quality and braking force are seriously incompatible, and the car body quality that increases day by day displays with the hypodynamic contradiction of braking more and more highlightedly.
[total weight of the rod-pulling type motor-tricycle that find the sixth of the twelve Earthly Branches has reached 800 kilograms (weight that indicate on the label).For example: the model of Mount Everest great river, Chongqing motor-tricycle Co., Ltd in August, 2009 production 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 that indicates on the label is 660 kilograms, wherein deadweight: 360 kilograms, load-carrying: 300 kilograms].
How to improve the service brake effect of three-wheeled vehicle? Every vehicle braked problem that relates to all be unable to do without the lever problem, and especially most three-wheeled vehicles be unable to do without the lever problem especially.
The action of the force to rotate around a fixed point called hard rod lever, for example: crowbar Bing other hand pump.Lever can be straight, also can bend, and " strong " is not necessarily rod, the general reference certain-length is arranged but under the effect of external force indeformable object.
Lever has " five elements ":
(1) fulcrum: lever is called fulcrum around the attachment point that rotates.When lever rotated, fulcrum was 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 the dynamic action line is called power arm.
(5) resistance arm: the vertical distance from fulcrum to the drag effect line is called resistance arm.
Fig. 1 is the back wheel pull-rod type service brake schematic representation of apparatus of motor-tricycle of the prior art.It comprises four levers: be positioned at each lever on two trailing wheel back-plates, sometimes, we also are called trailing wheel swing arm lever to it, are called for short the 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 the chaufeur underfooting) lever the chaufeur right crus of diaphragm, sometimes, we also are called foot pedal lever to it, and this foot pedal lever constitutes by stepping on arm 1, treadle 2, axle 11 and pedal 10; Also have a middle lever between three levers recited above, sometimes, we also are called rocker lever to it, and this rocker lever is made up of rocking arm 3, rocking bar 4 and axle 11; Be connected with pull bar 20 between the power arm (rocking arm 3) of the resistance arm of the lever of chaufeur underfooting (treadle 2) and middle lever, two resistance arms (rocking bar 4) on the middle lever respectively with two trailing wheel back-plates on the power arm (swing arm 5) of lever be connected with pull bar 22 with pull bar 21.(trailing wheel back-plate not shown in the figures, only illustrate be positioned at the brake shoe brake cheek of pulling at the bottom of this braking 30)
[for the convenience of narrating, sometimes, we also can be called first lever to the lever that is positioned at the chaufeur underfooting (foot pedal lever); Be called second lever to middle lever (rocker lever); Be called the back 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 back wheel pull-rod type brake equipment of motor-tricycle is formed by the back wheel pull-rod type brake equipment transformation of two-wheeled motor vehicle.We compare the back wheel pull-rod type brake equipment of motor-tricycle with the back wheel pull-rod type brake equipment of two-wheeled motor vehicle: the lever of finding their chaufeur underfooting almost is identical (comparing the lever of their chaufeur underfooting and back turbine/lever with the back turbine/lever; The proportionate relationship of its shape, size and power arm and resistance arm; All almost completely identical), their difference only is a lever in the middle of in the back wheel pull-rod type brake equipment of motor-tricycle, having had more.
Cause wheel to embrace not dead reason and just be middle lever.
For a long time; Domestic more than 200 families make the motor-tricycle and the electro-tricycle of the enterprise production of three-wheeled vehicle; The structure of nearly all middle lever is in full accord; That is: two resistance arms (rocking bar 4) on the middle lever equate, and equate with power arm (rocking bar 3) on the middle lever [in the motor-tricycle field, at home more than 200 in the enterprise of tame manufacturing motor-tricycle; The power arm of middle lever of only finding the motor-tricycle of several families enterprise production that list the back is slightly larger than resistance arm; Only find a producer (the Feitian five-pointed star board motor-tricycle that the fertile international heavy industry of Feitian, Zhucheng, Shandong Province thunder joint-stock company produces) in September, 2009, afterwards, found several producers (the big fortune in Luoyang, north are prone to big sun, Luoyang Mount Everest etc.) again in succession; In the electro-tricycle field, the middle lever of whole electro-tricycles all takes two resistance arms (rocking bar 4) to equate, and the structure that equates with power arm (rocking arm 3) on the middle lever].
In Fig. 1, if represent the pulling force of pull bar 20 with F;
The pulling force of representing pull bar 21 with M;
The pulling force of representing pull bar 22 with N;
The power arm of representing middle lever with R;
The resistance arm of representing middle lever 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 when balance, kinetic moment=resisting moment
That is: power * power arm=resistance * resistance arm
Specific to lever: F * R=M in the middle of above-mentioned * r+N * r
That is: F * R=r (M+N)
Because: R=r
So: F=M+N
Because two resisting moments are equal, that is: M * r=N * r
So: M=N
Can find out from top analysis: when two resistance arms of middle lever equate, and when 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 half of pulling force of pull bar 20 respectively,
That is:
Can find out from following formula: the pulling force of pull bar 21 equals pulling force half the of pull bar 20, and the pulling force of pull bar 22 also equals pulling force half the of pull bar 20.That is to say that in braking procedure, pulling force is through behind the middle lever, the size of pulling force will reduce half, and [strictly speaking, moment has reduced half the.When two resistance arms of middle lever equate, and when equating with power arm, pulling force has reduced half.In addition, above-mentioned conclusion also can be confirmed through experiment.Experimental technique is: three pull bars (pull bar 20, pull bar 21 and pull bar 22) are blocked from middle position; Connect a spring balance in each truncated position; Three pull bars connect three spring balances altogether; When we are applied to the application force that varies in size on the pedal 10, read the numerical value of three spring balances respectively, consequently: the pulling force of pull bar 21 equates with the pulling force of pull bar 22 all the time; And the pulling force of pull bar 21 equals pulling force half the of pull bar 20 all the time; The pulling force of pull bar 22 also equals pulling force half the of pull bar 20 all the time.For example: when the reading of the spring balance on the pull bar 20 was 10 kilograms, the reading of the spring balance on the pull bar 21 was 5 kilograms, and the reading of the spring balance on the pull bar 22 also is 5 kilograms; When the reading of the spring balance on the pull bar 20 was 30 kilograms, the reading of the spring balance on the pull bar 21 was 15 kilograms, and the reading of the spring balance on the pull bar 22 also is 15 kilograms; When the reading of the spring balance on the pull bar 20 was 60 kilograms, the reading of the spring balance on the pull bar 21 was 30 kilograms, and the reading of the spring balance on the pull bar 22 also is 30 kilograms etc.].
For a long time; Almost completely identical with the lever of the chaufeur underfooting of two-wheeled motor vehicle from the lever of the chaufeur underfooting of motor-tricycle with back turbine/lever with the back turbine/lever; People do not identify two resistance arms are set on middle lever; Pulling force is through behind the middle lever; Can cause pulling force to reduce half the result, thereby not identify the result that can cause the braking force drop by half, and then not recognize that the back wheel pull-rod type brake equipment of motor-tricycle exists the short shortcoming of power arm of lever.
[in recent years; Found that in succession the power arm of 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 the 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 reduced to 200 millimeter (for a long time; The length of the power arm of the foot pedal lever of motor-tricycle is almost completely 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 up and down, can regard as roughly approximately and reduce to about 200 from 260～280 millimeter); Like this; The power arm of lever is slightly larger than resistance arm outwardly, but the not increase in fact of the braking force of whole back wheel pull-rod type brake equipment, its purpose is not to two results that resistance arm produced on the middle lever; This has shown that the technical personnel of these several producers does not identify pulling force equally through behind the middle lever, and pulling force will reduce half the.(amplitude that increases from the power arm of middle lever and the simultaneously a large amount of reduction of power arm of foot pedal lever, said several producers do not identify pulling force through behind the middle lever, and pulling force will reduce half the.On the contrary; If the power arm of the foot pedal lever of motor-tricycle remains unchanged; Promptly still remain on the length of 260～280 millimeter roughly; And the length of the power arm on the middle lever equals the length sum of two resistance arms on this centre lever, can think that then people have recognized pulling force through behind the middle lever, and pulling force will reduce half the.Because when having only length when the power arm on the middle lever to equal the length of resistance arm of this centre lever of two-fold, just can make pulling force pass through in the middle of behind the lever, remain unchanged.For example: lever is provided with a power arm and two resistance arms in the middle of certain; The maxim of power arm is 200 millimeters; The maxim of one of them resistance arm is 100 millimeters, and the maxim of another resistance arm also is 100 millimeters, so; Pulling force is through behind this centre lever, and the size of its pulling force remains unchanged)].
Can find out from top analysis and experiment: existing motor-tricycle is with respect to two-wheeled motor vehicle; The car body quality of motor-tricycle has increased; But braking force has descended half the on the contrary, is approximately
of the braking force of two-wheeled motor vehicle
People both do not find, do not expect yet pulling force pass through in the middle of behind the lever, can change stealthily.People always habitually think to prejudice: the effect of middle lever only is the point of action that is used for changing power, does not change the size of power; And objective fact is: middle lever has not only changed the point of action of power, and variation has also taken place the size of power stealthily.
So the motor-tricycle braking effect is poor, wheel is embraced not dead basic reason and is two resistance arms on the middle lever.
To this structure the characteristic that reduces by half of intrinsic braking force, especially short and small that the power arm of the lever in the back wheel pull-rod type brake equipment of motor-tricycle just shows.
[specific to above-mentioned four levers, fulcrum is meant the center-point of the axle 11 of lever, i.e. axle center; Power and drag effect line are meant the bar heart line (cross-sectional plane of pull bar has a geometric center point, and the center-point of numerous cross-sectional plane couples together formed line, and we are called bar heart line to it) of pull bar; Power arm and resistance arm be meant axial line from lever (line of numerous AnchorPoint and the extended line of this line, we are called axial line to it, below all like this) to the vertical distance between the bar heart line of pull bar].
The motor-tricycle of domestic several manufacturer production that the maximum power arm of having selected below to find the sixth of the twelve Earthly Branches is bigger, listed maximum power arm and the maximum resistance arm of the maximum power arm of the swing arm lever in the back wheel pull-rod type brake equipment, the maximum power arm of foot pedal lever, middle lever:
(power arm of lever can be regulated, and in braking procedure, changes, and when swing arm 5, to swagger 3 be the maximum power arm when each other vertical with pull bar, common maximum power arm also can be called for short and be called power arm).
(in the prior art, the power arm of the lever on two trailing wheel back-plates equates that all two resistance arms on the middle lever equate that all promptly the braking force of two trailing wheels equates.For briefly, just list out the numerical value of one of them arm of force in these two arm of forces.For example: when listing " the maximum power arm of trailing wheel swing arm lever is 87 millimeters ", the maximum power arm that refers to two trailing wheel swing arm levers equates, and the maximum power arm of the swing arm lever of one of them trailing wheel is 87 millimeters.Again for example: when listing certain " the maximum resistance arm of middle lever is 70 millimeters ", refer at this and be provided with two resistance arms above lever of centre, and these two resistance arms equate that the numerical value of one of them resistance arm is 70 millimeters).
