Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
As shown in Figure 1; The utility model comprises foundation frame 2, motor 1, drive roll 3, driven cylinder 4, detection system 6, Displaying Meter 5 and locking system; Two drive rolls are fixed on the foundation frame through bearing seat, and two driven cylinders are individually fixed on two slide plates through bearing seat, and two slide plates place on the slideway on the foundation frame; Can horizontally slip, and link to each other with detection system; Detection system is made up of sensor, dynamic balance spring and dynamometry lever; The dynamic balance spring connects driven cylinder and dynamometry lever respectively; Driven cylinder is under the wheel lateral force effect; Overcome balancing spring elastic force and slide to the left or to the right, the dynamometry lever amplifies the back by sensor measurement with slippage, and shows through Displaying Meter; Locking system links to each other with driven cylinder, the locking of driven cylinder when being used for non-detection status.
Equipment in use, cylinder was lived by the locking system locking before this, so that the turnover of vehicle.After the front-wheel with automobile placed four cylinders, just the releasable locking system was rotated by driven by motor drive roll back roll driving just front-wheel, with simulated automotive state to overtake.Two front rolls are driven and can laterally be free to slide because support the bearing seat of two front rolls be fixed on two can about on the slide plate that is free to slide, just can obtain the sideslip amount of front-wheel thus.Causing lateral sliding takes place for front-wheel and ground basic reason then is the effect of the side force that exists between wheel and the ground, and its detection system can detect the size and Orientation of this side force, and changes it into electric signal and shown by Displaying Meter.Traditional sideslip detects and is to use the slide type side slip tester, and when detecting, vehicle need be with the platen lower and testing table of speed of a motor vehicle straight-line pass stably, and the method for the transversal displacement amount through measuring sideskid is checked front-wheel sideslip amount then.When using this equipment, the grasp of the speed of a motor vehicle and travel direction is a difficult point, if control is improper, testing result just might produce bigger error.Rotation drives to vehicle front and this adjustment platform is because be to use cylinder, thus need not to start the purpose that vehicle can reach detection, so well avoided the generation of problem.
In the vehicle ' process, the toe-in value of front-wheel and camber angle are the principal elements that influence is breakked away.During detection; If only consider the influence of toe-in of front wheel; In the wheel process; Driven cylinder will bear two unidirectional lateral forces: the one, because prenex existence; About two front-wheels attempts inwardly draw in and to produce, act on side force F outside on the driven cylinder
; The 2nd, the front-wheel drive power that driven cylinder bore is at its axial component F
.Force analysis is as shown in Figure 2.If only consider the influence of camber angle; In the wheel process; Driven cylinder also will bear two unidirectional side forces: the one, because the existence of flare; About two front-wheels attempts outwards open generation, act on interior on the driven cylinder to side force F
; The 2nd, the front-wheel drive power that driven cylinder bore is at its axial component F
.Force analysis is as shown in Figure 3.
As can be seen from the figure, the side force direction that toe-in of front wheel and front-wheel camber produce separately is opposite, and therefore when both mate ideal, driven cylinder will not receive the influence of side force; Therefore and the side force that produces and take place laterally to slide but when both mate when bad, driven cylinder will be experienced front-wheel.Simultaneously, this equipment testing system can detect this side force and change it into electric signal, is shown by Displaying Meter.Adjustment person can in time adjust in testing process based on the size and Orientation of instrument show value, makes Front wheel Alignment Parameters reach comparison rational matching relation, and the sideslip amount of front-wheel arrives minimum of a value.
In the detection adjustment of tradition sideslip amount, detect to separate often and carry out with adjustment, not only reduced work efficiency, and the degree of accuracy of adjusting is difficult to also be guaranteed.And the utility model of this equipment, make defective steering stabilizer detect with adjustment become possibility synchronously.In use, the design of driving and driven cylinder makes vehicle when static, can simulate its state to overtake.Because of vehicle need not to start,, promoted work efficiency greatly so can in testing process, accomplish adjustment to Front wheel Alignment Parameters.Simultaneously, the actual motion state of simulating vehicle can also be guaranteed the accuracy that front-wheel detects.In addition, be different from traditional slide type side slip tester, not only can reflect the sideslip amount of test vehicle during this Equipment Inspection, also can directly calculate the size and Orientation that the automobile of sening as an envoy to produces the skid force of sliding phenomenon, experimental data is more simple, directly perceived.The adjustment of making according to the skid force data also can obtain more accurate Front wheel Alignment Parameters matching relationship.
