Among the figure: 1. base plate; 2. motor; 3. speed reduction unit; 4. left butterfly spring group; 5. power sensor; 6. left connector; 7. left contact head; 8.s type camshaft; 9. right contact head; 10. right butterfly spring group; 11. hold-down nut; 12. supporting seat; 13. spacing pressing plate; 14. deep groove ball bearing; 15. spacing briquetting; 16. right connector; 17. bearing seat.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
A kind of load device of adjusting arm for detection of brake clearance as depicted in figs. 1 and 2, simulated the automobile load, comprise base plate 1, be provided with supporting seat 12 and bearing seat 17 at base plate, s type camshaft 8 is erected between supporting seat and the bearing seat, be that an end of s type camshaft is by being fixed of deep groove ball bearing 14 and bearing seat, and by the axially-movable of spacing pressing plate 13 restriction s camshafts; The other end of s type camshaft stretches in the supporting seat after passing spacing briquetting 15, and fixes by another deep groove ball bearing that is embedded in the spacing briquetting.
Comprise left butterfly spring group 4, right butterfly spring group 10, power sensor 5, left connector 6, left contact head 7, right contact head 9, right connector 16 in the supporting seat; The head of left contact head contacts with the upper point of s type camshaft, the afterbody of left contact head is designed with a boss screw thread, left connector namely is connected with left connector by this screw thread, one end of power sensor is connected with left connector, the other end is connected with an end of left butterfly spring group, the other end of left butterfly spring group is connected with supporting seat speed reduction unit output terminal outward, and the speed reduction unit input end is connected with the output shaft of motor.
The head of right contact head contacts with the lower point of s type camshaft, the afterbody of right contact head adopts the identical structure of left contact head to be threaded with right connector, one end of right butterfly spring group is connected with right connector, and the other end is fixing by the outer hold-down nut 11 of supporting seat.
According to adjusting arm self structure characteristics, will adjust arm and be enclosed within on the s camshaft, under the dynamic action in the external world, adjustment arm drive s camshaft is done the low-angle circular motion along its axis, the left and right sides small angle oscillation of direction shown in Figure 1.If free clearance is reasonable, then left contact head contacts with s camshaft top, and right contact head contacts with s camshaft bottom; As unreasonable, then the s camshaft has at least a side not contact with the contact head of both sides, adjusts arm namely by the self-adjusting function, adjusts this gap, under the repeatedly drive of exterior power, can so that this gap comes back in the rational scope, illustrate that this adjustment arm is qualified if adjust arm.
Designed brake clearance is adjusted the change procedure of the brake clearance of arm load simulating device simulated automotive in practical service environment.Before test beginning, the effective impulse level of the application of force source motor 2 that loads power is set, the decelerating effect motor by speed reduction unit 3 is that transmitted is regulated the gap between left contact head and the s camshaft.Left butterfly spring group changes rotatablely moving of motor output shaft into rectilinear motion, by the power sensor this motion is delivered on the left contact head, according to what and the positive and negative size that brake clearance can be set of motor transmitted.Again the automatic regulating function by adjusting arm so that the s camshaft contact with the contact head of both sides, the current power value of pulling-pressing force sensor 5 measurements this moment, the monitoring of one high accuracy displacement sensor is set in addition adjusts the displacement of arm, calculate the product of two sensors, feed back current torque value.Continuous Running Equipment is monitored the torque value whether current moment of torsion meets setting, can learn whether adjust arm can bring into play automatic regulating function for a long time.
