Abstract

An automobile pedal fatigue test bed comprises a frame and a worktable. A motor arranged on the frame is connected with a speed reducer; an eccentric wheel is connected onto an output shaft of the speed reducer; the eccentric wheel is hinged with one end of a connection rod; the worktable is positioned below the speed reducer; a supporting seat is fixed onto the worktable; one end of a rocking rod is hinged with the supporting seat; the other end of the rocking rod is connected with a connection block; the connection block is hinged with the other end of the connection rod; a roller is installed on the connection block; a supporting post is fixed onto the worktable; a spring is connected between the connection block and the supporting post; a pin shaft penetrates through the worktable; a stop cap is fixed to the upper portion of the pin shaft; a spring is sleeved on the portion of the pin shaft positioned below the stop cap; and the lower end of the spring is supported by a base fixed at the bottom of the frame. The automobile pedal fatigue test bed has the advantages of simple and reasonable structure, convenient use, accurate and reliable obtained test data and low use cost, and is an ideal fatigue test device of an automobile pedal.

Description

Fatigue test stand of automobile pedals

Technical field

The utility model relates to fatigue experimental device, specifically a kind of fatigue test stand of automobile pedals.

Background technology

At present in auto parts and components manufacturing enterprise, torture test for auto pedal does not have special device, have now and can only test with some general impact test apparatus the torture test of auto pedal, the shortcoming that adopts general impact test apparatus that auto pedal is tested existence is: the data specific aim of acquisition is not strong, and test is complicated, testing cost is higher.

The utility model content

The purpose of this utility model is to provide a kind of fatigue test stand of automobile pedals, and the data that this fatigue test board testing automobile pedal obtains data with strong points, that obtain are accurate.

For achieving the above object, the utility model adopts following scheme: fatigue test stand of automobile pedals, it has frame and worktable, motor and speed reduction unit that frame is provided with link, be connected with eccentric wheel on the output shaft of speed reduction unit, one end of an eccentric wheel and a connecting rod is hinged, worktable is positioned at the below of speed reduction unit, be fixed with a bearing on worktable, an end and the bearing of a rocking bar are hinged, and the other end of rocking bar is connected with a contiguous block, the other end of this contiguous block and connecting rod is hinged, roller is housed on the contiguous block, is fixed with a pillar on the worktable, contiguous block is connected with spring with an intercolumniation, passed a bearing pin on the worktable, the top of bearing pin is fixed with a retaining cap, and bearing pin is positioned on the following part of retaining cap and is with spring, and the lower end of spring is by the base support that is fixed on the frame bottom.

By such scheme as seen, auto pedal is fixed on the worktable, the swing part of pedal is connected with bearing pin, and with the roller on the trample part aligning contiguous block of pedal, starter motor, motor drives cam and link motion by speed reduction unit, and then make rocking bar and contiguous block pump, can constantly impact the trample part of pedal by the roller on the contiguous block, the process that roller impacts the trample part of pedal then is the process of anthropomorphic dummy's foot pedal, can realize the torture test to auto pedal thus.

The utility model is simple and reasonable for structure, and is easy to use, and the experimental data that it obtains is accurate, reliable, and its use cost is low, is the desirable fatigue experimental device of auto pedal.

Description of drawings

The structural representation of Fig. 1 the utility model one embodiment;

The right view of Fig. 2 Fig. 1.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2

Motor 2 and speed reduction unit 3 that the frame 1 of this fatigue test stand of automobile pedals is provided with link, be connected with eccentric wheel 4 on the output shaft of speed reduction unit 3, one end of an eccentric wheel 4 and a connecting rod 5 is hinged, worktable 16 is positioned at the below of speed reduction unit 3, the end and the bearing 13 that are fixed with a bearing 13, one rocking bars 12 on worktable are hinged, and the other end of rocking bar 12 is connected with a contiguous block 9, this contiguous block 9 is hinged with the other end of connecting rod 5, and roller 10 is housed on the contiguous block 9.Be fixed with a pillar 11 on the

worktable

16,11 on contiguous block 9 and pillar are connected with spring 7.Passed a bearing pin 14 on the worktable 16.Be fixed with pair of supporting 15 on worktable, bracing frame 15 is used for the support to auto pedal.On pillar, be coated with post bolt 6, be coated with post bolt 8 on the contiguous block 9, be connected in contiguous block 9 and be connected with the two ends of post bolt 6, post bolt 8 with the spring 7 of 11 on pillar.

Referring to Fig. 2

The top of bearing pin 14 is fixed with a retaining cap 20, and bearing pin 14 is positioned on the following part of retaining cap and is with spring 19, and the lower end of spring 19 is supported by the base 18 that is fixed on the frame bottom.

As seen from Figure 2, auto pedal 17 is fixed on the worktable, the swing part of pedal 17 is connected with bearing pin 14, and with the roller 10 on the trample part aligning contiguous block of pedal 17, starter motor 2, motor drives cam 4 and connecting rod 5 motions by speed reduction unit 3, and then makes rocking bar 11 and contiguous block 9 pump, the trample part of pedal 17 can be constantly impacted by the roller on the contiguous block 9 10, torture test can be realized auto pedal.In addition, at the trample part of pedal 17 during at every turn to lower swing, can compression spring 19 once, after the trample part of roller 10 and pedal separated, spring 19 can reset again.To a certain pedal after bump after a while, the bump number of times that pedal stands can be calculated by the velocity gauge of speed reduction unit, when the deflection that tests out spring 19 during less than the amount of regulation, illustrate this pedal near or reach fatigue limit.Can draw the fatigue limit of pedal.
