Description

The detection method of automobile sideslip detector and sideslip
Technical field
The present invention relates to the detector that breaks away, specifically relate to the detection method of a kind of automobile sideslip detector and sideslip.
Background technology
When Automobile Design, deflecting roller mostly is provided with very little camber angle, its purpose is outside one's consideration except the transverse arch on the compensation elasticity (or propons elasticity) of independent suspension and stub gap and adaptation road surface, mainly be to wear the distance at place and tire print center, improve automobile brake, control stability and ease of steering when driving in order to reduce main pin axis.But, this ever-present side rake angle, can make the left and right wheels effect direction opposite with the corresponding side force of side rake angle, when tire wear is increased, cause the eccentric wear of tire, and produce extra power consumption, for fear of this situation, certain toe-in angle of deflecting roller commonly used is offset the side force that side rake angle produces during design.Facts have proved that wheel side sliding can cause resistance to rolling to increase, travel direction stability degenerates, tire increases the weight of wearing and tearing, road fuel consumption increases and hard steering, influences vehicle operation performance and fuel economy, easily causes the potential danger of driving accident.
Therefore, relevant rules have all been formulated to break away check of automobile in countries in the world.Standard GB 7258-2004 " the motor vehicle security of operation technical conditions " regulation that China is existing: with slip indicator check front-wheel sideslip amount, its value must not surpass 5m/km.Stipulate in Japan's " road transporting safety standard " 6 sections of 4: the sideslip amount of the above automobile steering roller of four-wheel, the 1m that travels is defective above 5mm.
In the automobile use,, cause the wheel alignment misalignment because the distortion and the wearing and tearing of vehicle frame, axletree, steering mechanism have changed original geometric angle and size numerical value.Destroyed the optimum matching relation between camber angle and prenex these two parameters, had only the employing dynamic testing method, simulated automotive road traveling process is readjusted camber angle and prenex matching relationship.In recent years because static wheel alignment meter adopts optical profile type or computermatic four-wheel position finder to carry out the measurement of geometric angle mostly, therefore because the tire eccentric wear that initial reason such as the static immobilization parameter matching error of tire, rigging error cause decreases less, and that the situation that eccentric wear decreases appears in the tyres for passenger cars that continues to run at high speed on highway is more, particularly occurs in many tire positional parameters and is provided with on the normal intermediate car.Trace it to its cause, will consider the particularly dynamic perfromance of tire suspension positional parameter influence that the tire eccentric wear is decreased of car load.Therefore detecting the dynamic change of camber angle and prenex positional parameter in the vehicle driving process, is to solve the vehicle tyre eccentric wear to decrease and need a key factor considering.
The domestic and international at present most of side slip testers in usefulness all are slide types, and vehicle front is passed through on slide plate, detect the method for the transversal displacement amount of slide plate and check the sideslip amount.The slide type sideslip is tested platform can be divided into single slide type and two kinds of two slide types by its version, and two slide type side slip testers generally all are that two plates link.Two plate coordinated type side slip testers are measured quantitative indicating device and sideslip by mechanical part, sideslip amount detecting device, sideslip and are measured several parts such as qualitative display device and form.
Vehicle front is passed through on slide plate, check the sideslip amount with the method for the transversal displacement amount of left and right direction slide plate.According to the specification difference of side slip tester, the longitudinal length of slide plate has three kinds of 500mm, 800mm and 1000mm.The actual detected distance that is front-wheel is 0.5m, 0.8m, 1.0m.Because slide plate limited length, it is be expert at sideslip situation in crossing of simulated automotive well, and in the middle of reality was used, the error of testing result was big, repeatability is relatively poor, automobile is difficult for grasping through the standard speed (4km/h) of slide plate, and the variation of speed is very big to the measurement result influence.
Sideslip is meant because prenex and camber angle mismate in vehicle traveling process, produce a kind of interaction force between wheel and the ground, and this acting force makes tire be in the sliding state of limit rolling perpendicular to vehicle traveling direction.Definition according to the sideslip amount: the sideslip amount is: when straight-line travelling one segment distance (X), and the transversal displacement of wheel (Y).Unit: m/km, its computing formula: sideslip amount=Y/X, but because the too short 1m of simulation operating range of slide type side slip tester (or 0.5m, 0.8m), promptly measuring distance is too short, causes measuring accuracy not high, and error is very big.Simultaneously, wheel is fixed on the vehicle frame, and rubber for tire has good elasticity.In straight-line travelling, because the elasticity of rubber for tire, can the storage area strain energy of distortion, when the transversely deforming amount reaches certain value, transverse force is during greater than side-friction, resilience, transversely deforming reduces.This periodic variation has constituted the phenomenon of sliding in the rolling limit, limit of deflecting roller.Because when wheel rolled on slide plate, the deflection of tire was all different, is the reason that causes slide type slip indicator poor repeatability at every turn.
In sum, error is big, and inaccurate, poor repeatability is that the structure by slide type slip indicator itself is caused.The underlying cause is that the front-wheel distance of being travelled on slide plate is too short, cause the recoverable amount of slide type side slip tester very big, yet instream factor is really very low.
The patent No. is the side slip tester that the utility model patent of ZL200720106503.2 discloses band side force of tire releasing mechanism, and this testing table is the improvement to the slide type slip indicator.Comprise the detection slide plate that is arranged on ground horizontal slip, described detection slide plate is provided with the side force of tire releasing mechanism along the top of automobile direct of travel, and described side force of tire releasing mechanism comprises the release board of horizontal slip and the resetting means of release board.Owing to set up the side force of tire releasing mechanism before detecting slide plate, when wheel advanced in this mechanism, the lateral elasticity deformation of tire obtained discharging, and did not begin this moment to detect, and just the lateral elasticity deformation of tire was got rid of outside detecting.And when the front end that flattens section touched the detection slide plate, detection promptly began; When the front end that flattens section touches ground, detect promptly and finish, so just the tyre collapse section of non-quantitative is also got rid of outside detection limit.
Though patent Z1200720106503.2 has carried out certain improvement to the slide type slip indicator, because front-wheel is too short through the distance (the longest 1m) of slide plate, for measurand, the data of sampling are very little; Require (4km/h) too harsh to the speed of a motor vehicle that detects vehicle,, also have a strong impact on accuracy and the repeatability of sideslip because the speed during vehicle turnover slide plate can produce very big impact to the test slide plate.
In automobile steering roller sideslip test item, the factor that influences testing result mainly contains following several respects:
(1) influence of the speed of a motor vehicle to breakking away: two automobiles that technology status is good, may be because the vehicle difference, break away and the funtcional relationship of the speed of a motor vehicle will be not to, also difference of the sideslip of two cars amount under the same speed of a motor vehicle.For same car, speed of a motor vehicle difference also can cause different testing results.In reality is breakked away detection, owing to multiple reason is difficult to the control speed of a motor vehicle within claimed range, be easy to cause measuring error, cause wheel alignment condition judgement misalignment.At present, when utilizing side slip tester that the deflecting roller sideslip is detected, slowly by testing table, whether this speed of a motor vehicle requires reasonable with low speed (4km/h) for the regulation vehicle, is worth further and inquires into and research.
(2) influence of load to breakking away: the camber angle of deflecting roller is along with the variation of lorry loading amount changes, and it is more little that steeraxle loads the big more then steering wheel camber of load, but prenex variation is little.Especially be the independent suspension vehicle for steeraxle, load is bigger to the variable effect of camber angle.Have data to show: unbalance loading is compared during with zero load, and what steering wheel camber had differs 0.70; Steering wheel camber when on the contrary, respectively sitting a people with zero load about the automobile front row is more or less the same substantially.The variation of steering wheel camber must cause the variation of wheel side sliding.Automobile load difference, deflecting roller are breakked away also inevitable inequality.Therefore, when detecting automobile steering roller and break away, only sit a driver on the operator seat and can make vehicle unbalance-loading, steering wheel camber changes, and the sideslip testing result can not the correct response camber angle and the match condition of toe-in value.Therefore, good flare and prenex matching relationship, not only relevant with the adjustment numerical value under the empty wagons static state, and also relevant with the structural parameters and the service condition of vehicle.
(3) influence of tire pressure to breakking away: the tire pressure increase can make the wheel side sliding amount increase usually.But for truck tire, this in confused situation show, even the air pressure of some truck tire when increasing the sideslip amount reduce on the contrary.
(4) influence of motoring condition: automobile wheel under different transport conditions can be changed by the side force of acting force difference, the especially tire on ground.Therefore, when automobile crossed side slid platform with different transport conditions such as acceleration, decelerations, its testing result was just different.
(5) influence of automobile other technologies situation: the gap of automotive wheel, axle and suspension also can influence the testing result of sideslip amount.The position random variation of stub in gum cover causes the discreteness of sideslip amount testing result more outstanding in the time of can making each detection such as, main pin of automobile gum cover wearing and tearing.
In sum, error is big, and inaccurate, poor repeatability is that the structure by slide type slip indicator itself is caused, and its reason is the operating range with front-wheel, micro to 1m (or 0.5m, on slide plate 0.8m), the analogue measurement that breaks away.Though adopted the new technology and the new method of many improvement slide type dynamic test stands both at home and abroad, the influence of all can't the dynamic similation automobile vehicle dynamic being breakked away in straight-line travelling process medium velocity, load.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of and can accurately test under the different speed of a motor vehicle, different loads condition, the automobile sideslip detector of the horizontal value of sideslip of deflecting roller and the detection method of sideslip.

2. satisfy among the GB GB7258-2004 " motor vehicle security of operation technical conditions " and detect requirement, good testing result and repeatability are arranged breakking away.Transversal displacement sensor (Y to) adopts " floating zero " metering system, by choosing the sampling time, can filter the initial elasticity lateral deviation distortion of tire and the transverse movement gap of mechanical driving part.Because the flexible distortion of tire of vehicle, mechanical driving part has movement clearance, measure transversal displacement by choosing the sampling time, can allow vehicle in the chain-wheel mechanism that the plane carrier bar is formed, travel behind one section initial distance, carry out data aggregation and sampling again, therefore need to adopt " floating zero " metering system, the value of sideslip that makes tested vehicle is good reproducibility as a result.
3. can measure the survey cunning value of forerunner's deflecting roller under sliding value of survey under the friction speed, under the different loads and the effect of different driving power.The present invention can ignore the shock effect of vehicle turnover test board to measurement result fully.Owing to can infinitely amplify the operating range of tested vehicle, therefore can measure the value of sideslip under friction speed, different loads, can be used for accurately mating the suspension positional parameter of steering front wheel.
