Description
Technical Field
The utility model relates to an improvement of a durability test device of a clutch pedal.
Background
At present, the main clutch pedal manufacturers and the whole vehicle manufacturers in China mainly use a pneumatic system which takes a linear cylinder as a main device for durability test examination on the three pedals, and the hydraulic servo system test device has the main problems of high test cost and complex installation test and adjustment test device. The pedal endurance test device using the air source as power has the disadvantages that the test operation is not smooth due to the instability of the air source, the movement stroke of the magnetic switch cannot be accurately controlled due to the inertia of the air cylinder, and the test device is not attractive enough and has great noise due to complex pneumatic elements such as an air pipe, an electromagnetic valve, a filter and the like required by pneumatic equipment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a durability test device for a clutch pedal, which is stable and reliable in fixing the clutch pedal and low in noise in a test process.
In order to achieve the purpose, the utility model adopts the following technical scheme, and the durability test device of the clutch pedal is characterized in that: a bracket for fixing the arm lever of the clutch pedal and an electric cylinder for driving the clutch pedal body.
In the technical scheme, the power mechanic mechanism for driving the clutch pedal to swing is changed into the electric cylinder, the electric cylinder replaces hydraulic servo equipment to carry out the fatigue endurance test of the clutch pedal, the test cost is greatly reduced, the test efficiency is improved, the test mode is used, the stroke of the clutch pedal is manually adjusted, the displacement is accurate, a lot of troubles in adjusting the clutch stroke are reduced, the time is saved, and the device is easy to install, good in safety performance and low in noise.

Detailed Description
As shown in fig. 1 and 2, a durability test apparatus for a clutch pedal includes a bracket 10 for fixing a clutch pedal arm 1 and an electric cylinder 20 for driving a clutch pedal body.
The upper end of a clutch pedal arm rod 1 is connected to a support 10, the clutch pedal arm rod 1 can normally swing, power for driving the clutch pedal to press down is completed by an electric cylinder 20, and a clutch assembly is responsible for returning. The electric cylinder 20 with the power supply as the power is obliquely arranged according to the direction of normally pressing the clutch pedal, the loading end of the electric cylinder 20 is arranged perpendicular to the geometric center of the surface of the clutch pedal, and the displacement track of the actuator is controlled by the electric cylinder controller by taking the running track of the clutch pedal as the reference, so that the motion track of the actuator meets the test requirement of the motion track of the clutch pedal.
As shown in fig. 2, the bracket 10 includes vertical plates 11 arranged vertically at intervals, a mounting plate 12 is arranged between the two vertical plates 11, the left and right sides of the mounting plate 12 have axial holes 111 through which trunnions 121 are inserted on the vertical plates 11, and the two trunnions 121 form a rotating fit, and the trunnions 121 located in the horizontal direction are flush with the plate surface of the mounting plate 12.
The support 1 is used for ensuring the normal swing of the clutch pedal, specifically, the upper end of the clutch pedal arm rod 1 is fixed on the mounting plate 12, and the mounting plate 12 is connected with the vertical plate 11 in a rotating manner so as to ensure the normal swing of the clutch pedal arm rod 1.
The periphery of the shaft hole 111 on the vertical plate 11 is provided with an arc hole 112 with the same diameter, and the arc hole is arc-shaped
The center of curvature of the hole 112 is concentric with the shaft hole 111, and the mounting plate 12 is provided with a shaft rod which is in sliding fit with the arc-shaped hole 112. The provision of the arcuate aperture 112 has the effect of assisting in spacing and sharing the weight load.
Preferably, the arc-shaped hole 112 with the same diameter at the outer circumference of the shaft hole 111 on the vertical plate 11 is divided into an upper section and a lower section. More preferably, an arc hole 112A with a large curvature radius is further provided outside the arc hole 112 with a small curvature radius. As shown in fig. 2, the shaft 122 closer to the trunnion 121 may be a threaded rod segment, which penetrates through the arc-shaped hole 112 and then the connection nut may limit the distance between the plate edge of the mounting plate 12 and the vertical plate 11, and the shaft 123 farther from the trunnion 121 may be a quadrilateral rod with a sector-shaped cross section, which cooperates with the inner and outer side hole walls of the arc-shaped hole 112A to bear the gravity load and has a limiting effect.
