Abstract
The invention discloses a device for testing the reset force of a reset spring of a parking stay rope. The device for testing the reset force of the reset spring of the parking stay rope comprises a base plate, a first supporting plate, a second supporting plate, a sliding sleeve, a pull rod the reset spring, wherein the first supporting plate is arranged at one end of the base plate, the second supporting plate is arranged at the other end of the base plate, the sliding sleeve is arranged on the first supporting plate, the pull rod is arranged on the second supporting plate and the sliding sleeve, and the pull rod is sleeved with the reset spring. One end of the reset spring abuts against the second supporting plate, and the other end of the reset spring abuts against the end face of the sliding sleeve. The end, extending out of the sliding sleeve, of the pull rod is connected with a limiting sleeve. The end, extending out of the second supporting plate, of the pull rod is provided with a tension sensor. According to the device for testing the reset force of the parking stay rope reset spring, the stay rope is connected with the tension sensor in the testing device, the stay rope is controlled by a parking handle to move, the sliding sleeve moves to compress the reset spring, a test result is obtained by simulating the change of the reset spring on the stay rope along with the stay rope, the measurement accuracy is high, and the detection speed is high.
Description
Technical field
The present invention relates to a kind of frock, particularly the detection frock of the drag-line stroke variable quantity of a kind of parking cable of automobile in braking procedure.
Background technology
The action of parking brake, for connecting parking brake and rear drum brake, is passed to rear drum brake by the parking drag-line of automobile, thus produces the effect of parking.In parking process, the reset force of drag-line back-moving spring is the important indicator weighing parking drag-line performance, therefore needs to carry out Measurement accuracy to it.
But be all that drag-line back-moving spring is measured separately in prior art, instead of carry out force measurement by under back-moving spring and drag-line bonding state, therefore its measuring accuracy is poor.
Summary of the invention
In view of this, the object of this invention is to provide a kind of parking drag-line back-moving spring reset force proving installation, to solve the problem that in prior art, drag-line back-moving spring reset force measuring accuracy is poor.
Parking drag-line back-moving spring reset force proving installation of the present invention, comprise base plate, the first back up pad be arranged on base plate one end, the second back up pad being arranged on the base plate other end, the sliding sleeve be arranged in the first back up pad, the back-moving spring that is arranged on the pull bar on the second back up pad and sliding sleeve and is enclosed within pull bar, described back-moving spring one end withstands in the second back up pad, the other end withstands on sliding sleeve end face, one end that described pull bar stretches out sliding sleeve is connected with stop collar, one end that described pull bar stretches out the second back up pad is provided with pulling force sensor.
Further, described stop collar is the thread bush coordinated with pull rod screw.
Further, described first back up pad is provided with bar hole, the first back up pad is by the screw that coordinates with bar hole, be fixed on base plate in the mode adjustable along pull bar axial location.
Beneficial effect of the present invention:
Parking drag-line back-moving spring reset force proving installation of the present invention, drag-line is connected with the pulling force sensor in measurement mechanism, then control drag-line by parking handle to move, sliding sleeve moves and then compression reseting spring, testing result draws on drag-line, with the change of drag-line stroke at analog reset spring, accuracy of measurement is high, and detection speed is fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of parking drag-line back-moving spring reset force proving installation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment parking drag-line back-moving spring reset force proving installation, comprise base plate 1, be arranged on the first back up pad 2 on base plate one end, be arranged on the second back up pad 3 of the base plate other end, be arranged on the sliding sleeve 4 in the first back up pad, be arranged on the pull bar 5 on the second back up pad and sliding sleeve, and the back-moving spring 6 be enclosed within pull bar, described back-moving spring one end withstands in the second back up pad, the other end withstands on sliding sleeve end face, one end that described pull bar stretches out sliding sleeve is connected with stop collar 7, one end that described pull bar stretches out the second back up pad is provided with pulling force sensor 8.
When adopting the present embodiment parking drag-line back-moving spring reset force proving installation to detect, drag-line is connected with the pulling force sensor in measurement mechanism, then control drag-line by parking handle to move, sliding sleeve moves and then compression reseting spring, namely the reset thrust of back-moving spring measured by pulling force sensor, testing result draws on drag-line, with the change of drag-line stroke at analog reset spring, and accuracy of measurement is high, and detection speed is fast.
As the improvement to the present embodiment, described stop collar 7 is the thread bush coordinated with pull rod screw, and dismounting is easy to adjust, can improve test job efficiency.
As the improvement to the present embodiment, described first back up pad is provided with bar hole 9, first back up pad is by the screw that coordinates with bar hole, be fixed on base plate in the mode adjustable along pull bar axial location, this improvement makes the installation site by changing the first back up pad to simulate the parking stroke change of parking drag-line under different installation site, measures better comprehensive.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
