Abstract
The utility model discloses a fatigue testing device for an automobile pedal, which is used for testing the fatigue strength of the automobile pedal (1). The testing device is provided with a test-piece installation bracket (3); the automobile pedal (1) is fixedly arranged on the test-piece installation bracket (3) through a hole at the end part of the pedal and is connected with a spring (2) through a test-piece installation pin shaft (10) and an installation support seat (10); the testing device is provided with an air cylinder; the end part of a piston rod of the air cylinder acts on a pedal cushion of the automobile pedal (1). By adopting the technical scheme, a test bench adopts a welding rack, the structure is simple and compact, and the manufacturing is convenient; the loading force is flexible and adjustable, and the friction force of intermediate links is reduced, thereby approaching to the actual working status of the pedal; the operation is convenient, and the labor intensity of test workers is reduced; the probability of work accident is reduced, the reliability of the testing device is enhanced, and the test interruption frequency is decreased.
Description
Technical field
The utility model belongs to the technical field of automobile making, relates to the technology of auto parts and components test technology equipment, and more particularly, the utility model relates to a kind of auto pedal fatigue experimental device.
Background technology
In the prior art, the automobile clutch pedal torture test generally all is to adopt counterweight or spring to accomplish through devices such as wire rope and pulleys to load.Its shortcoming is:
1, can not imitate the actual working state of pedal fully, the intermediary movements link is too many, causes afterburning inaccurate;
2, the labour intensity of testing crew is big, because during general clutch pedal torture test, and the counterweight that 100～200kg that Clutch main cylinder mounting hole place need load is heavy, concerning manually-operated, weight is too big;
Industrial accident takes place when 3, testing easily, and wire rope ruptures easily in the process of the test, and test is interrupted often.Making the single test wire rope will break 3～5 times.
The utility model content
The utility model provides a kind of auto pedal fatigue experimental device, its objective is that being implemented in test loads easily.
To achieve these goals, the technical scheme taked of the utility model is:
The auto pedal fatigue experimental device that the utility model provided; Be used for auto pedal is carried out the test of fatigue strength; Described test unit is provided with the test specimen mounting bracket; Described auto pedal passes through on the described test specimen mounting bracket of the hinged or fastening installation in hole of its end, and is connected with spring through test specimen installation bearing pin and erection support; Described test unit is provided with cylinder, and the piston rod end of described cylinder acts on the foot pedal pad of described auto pedal.
Described spring housing is on spring conductor rod; Described test unit is established spring stop, and described spring stop is fixed on the described test specimen mounting bracket through the baffle plate set bolt, and adopts setting nut fastening; One end bearing of described spring is on described spring stop.
The utility model adopts technique scheme, and test-bed is the welded type frame, and is simple in structure, compact, easily manufactured; Loading force can flexible, and the friction force of cutting down the number of intermediate links is near the actual working state of pedal; Easy to operate, reduced the labour intensity of testing crew; Reduce the probability that industrial accident takes place, strengthened the reliability of testing equipment, reduced the number of times that test is interrupted.
Description of drawings
Make brief description in the face of the expressed content of the accompanying drawing of this instructions and the mark among the figure down:

Embodiment
Contrast accompanying drawing below,, the embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
The utility model proposes for the exploitation automobile clutch pedal torture test of automobile production enterprise.
Like the structure of the expressed the utility model of Fig. 1, be a kind of auto pedal fatigue experimental device, be used for auto pedal 1 is carried out the test of fatigue strength, described test unit is provided with test specimen mounting bracket 3.
Described test specimen mounting bracket 3 is installed on test-bed through mounting hole 9 and is fixing.
In order to solve the problem that exists at the described present known technology of this instructions background technology part and to overcome its defective, be implemented in the goal of the invention that test loads easily, the technical scheme that the utility model is taked is:
Auto pedal fatigue experimental device as shown in Figure 1, that the utility model provided, described auto pedal 1 passes through on the described test specimen mounting bracket 3 of the hinged or fastening installation in hole of its end, and is connected with spring 2 through test specimen installation bearing pin 10 and erection support 8; Described test unit is provided with cylinder, and the piston rod end of described cylinder acts on the foot pedal pad of described auto pedal 1.
Described
The utility model has following advantage:
1, adopt the welded type frame, compact conformation, easily manufactured;
2, loading force can flexible, and the friction force of cutting down the number of intermediate links is near the actual working state of pedal;
3, simple in structure, easy to operate, reduced the labour intensity of testing crew;
4, reduce the probability that industrial accident takes place, strengthened the reliability of testing equipment, reduced the number of times (making the single test wire rope in the past will break 3～5 times) that test is interrupted.
Described spring 2 is enclosed within on the spring conductor rod 6; Described test unit is established spring stop 4, and described spring stop 4 is fixed on the described test specimen mounting bracket 3 through baffle plate set bolt 5, and adopts setting nut 7 fastening; One end bearing of described spring 2 is on described spring stop 4.
Through the cylinder of torture test stand, loading force F on foot pedal pad.
The loading force that can calculate at the Clutch main cylinder outlet aperture according to the lever ratio i of pedal is F * i, according to the rigidity formula of spring:
P’＝Gd
4/(8nD
3)
In the formula:
The modulus of shearing of G---spring material;
The diameter of d---spring material;
The number of active coils of n---spring;
The middle footpath of D---spring.
By formula F * i=P ' * Δ L, can calculate the impulse stroke Δ L of spring.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
