Abstract
The utility model relates to a test bed for detecting the alignment of a redirector, belonging to the field of test equipment of automobile redirectors. The test bed consists of a test bed frame, a spring load, a redirector mounting bracket, a redirecting inertia plate, an angle sensor and a measurement display terminal. A tested redirector is installed on the redirector mounting bracket; the rack end of the redirector is connected with the spring load, and the end of an input shaft of the redirector is provided with the redirecting inertia plate and the angle sensor; and the angle sensor is connected with the measurement display terminal. Since the spring load is adopted for loading, signals are transferred to the measurement display terminal through the angle sensor to collect angle and time and display a curve relationship between corresponding angle and time so as to enable the load in testing the alignment to be closer to the actuality, and meanwhile, a redirecting residual angle in aligning can also be measured. The utility model solves the problem that the prior test bed can not really reproduce the aligning speed and the aligning residual angle when a real vehicle aligns, and has the advantages of simple structure, low manufacture cost, simple operation and real measuring result.
Description
Technical field:
The utility model relates to a kind of steering gear testing table, designs a kind of testing table that detects the steering gear returnability especially, belongs to automobile steering device testing equipment field.
Background technology:
Along with the user is more and more higher to the requirement of automobile operating performance, one of performance that return performance is mainly examined as automobile also inevitably needs to improve.And existing steering gear returnability detects testing table, is that the input shaft (input end) with steering gear is in free state, and the tooth bar (output terminal) that promotes steering gear by the straight line force actuator realizes detecting (as shown in Figure 2) of test.It is comparatively simple that this returnability detects test platform structure, and testing process is easy, uses commonplace.But when installing and using on real vehicle owing to steering gear, input shaft is connected with steering column and bearing circle, is not to be in free state; Automobile is returning timing simultaneously, load that the steering gear rack output terminal is subjected to and tooth bar are set to certain proportionate relationship apart from centre bit, therefore, existing steering gear test of returnability platform can not really reproduce the positive speed of returning that real vehicle returns timing and reach back positive remaining angle, can not make visual evaluation on testing table to time plus effect of steering gear.
Summary of the invention:
The purpose of this utility model is: a kind of deficiency that existing steering gear returnability detects testing table that overcomes is provided, employing is installed load on spring additional with simulation real vehicle wheel-borne load at automobile steering device tooth bar end, install additional at the automobile steering device input shaft end and to turn to of the load of inertia plate, and install angular transducer additional and measure the steering gear test of returnability platform that the steering gear restoring time reaches back positive remaining angle with simulation real vehicle bearing circle and steering column.
The utility model is to realize above-mentioned purpose by the following technical solutions:
This steering gear test of returnability platform by test-bed, load on spring, steering gear mounting bracket, turn to inertia plate, angular transducer and measure display terminal and constitute, the steering gear mounting bracket is fixed on the test-bed, tested steering gear is installed on the steering gear mounting bracket, it is characterized in that: rigidly fix a load on spring that is connected with the steering gear rack end on the test-bed, the input shaft end of steering gear is equipped with and turns to the inertia plate, turn on the inertia plate angular transducer is housed, angular transducer connects by transmission line measures display terminal.
The utility model advantage compared with prior art is:
This steering gear test of returnability platform adopts load on spring to load at the tooth bar end, and install additional at input shaft end and to turn to the inertia plate, thereby make more closing to reality of the load of steering gear when detecting return performance, can measure steering angle simultaneously, thereby can measure back the residual angle of turning to of timing, solve existing steering gear returnability detection testing table and can not really reproduce the problem that positive speed reaches back positive remaining angle of returning that real vehicle returns timing.And simple in structure, cheap for manufacturing cost, easy and simple to handle, time plus effect of steering gear when measurement result is pressed close to the real vehicle installation more.
Description of drawings:
Accompanying drawing is the structural representation of steering gear test of returnability platform.
Among the figure: 1, test-bed, 2, load on spring, 3, the steering gear mounting bracket, 4, steering gear, 5, turn to the inertia plate, 6, angular transducer, 7, measure display terminal.
Embodiment:
This steering gear test of returnability platform is by test-bed 1, load on spring 2, steering gear mounting bracket 3, turn to inertia plate 5, angular transducer 6 and measurement display terminal 7 constitute, steering gear mounting bracket 3 is fixed on the test-bed 1, tested steering gear 4 is installed on the steering gear mounting bracket 3, rigidly fixed a load on spring 2 on the test-bed 1, pull bar on the tooth bar end of load on spring 2 and tested steering gear 4 is connected, be equipped with on the input shaft end of steering gear 4 and turn to inertia plate 5, turn to angular transducer 6 is housed on the inertia plate 5, angular transducer 6 connects the computer display system (referring to accompanying drawing) of measuring display terminal 7 by transmission line.
The course of work of this steering gear test of returnability platform is as follows:
After tested steering gear 4 is installed on the steering gear mounting bracket 3, tested steering gear 4 is in the centre position of stroke, then the load on spring 2 of the pull bar on the tooth bar end of steering gear 4 when being in free state is connected, and angular transducer 6 is made zero.After being ready to complete, the input shaft of tested steering gear 4 is rotated the angle of an ormal weight, the spring of load on spring 2 is compressed, and then the input shaft of release steering gear 4, then input shaft is at load on spring 2 and turn under the double action of inertia plate 5, can rotate to the stroke centre position, angular transducer 6 passes the signal along to measures display terminal 7, by the computer display system of measuring display terminal 7 angle is gathered in time, and demonstration graph of a correspondence, can obtain the curved line relation of angle and time, measure steering gear and return the positive time and turn to remaining angle.
