In the connection structure of above-mentioned automobile clutch pedal arm, described protecting sleeve forms by two spider concentric butt joints, and two above-mentioned convex annular are along laying respectively on the lateral wall of two spiders.Two spiders insert from the two ends of axle sleeve respectively, make things convenient for the installation of protecting sleeve.
In the connection structure of above-mentioned automobile clutch pedal arm, described protecting sleeve adopts polyurethane material to make.The wear-resisting performance of polyurethane is good, and manufacturing processing technic is simple.
In the connection structure of above-mentioned automobile clutch pedal arm, an end of described bearing pin is fixed with the jump ring that a pair of bearing pin carries out axial location.Bearing pin inserts from an end, and locate by jump ring the insertion end end, prevents axially displaced.
Compared with prior art, the connection structure of this automobile clutch pedal arm has the following advantages:
1, owing to be provided with a protecting sleeve between the inwall of connecting bore and the bearing pin lateral wall, therefore can avoid the bump of connecting bore inwall and bearing pin, reduce abnormal sound, improve driver comfort.
2, owing to have the convex annular edge on the protecting sleeve, therefore can avoid the biside plate of U-shaped shift fork and the bump between the clutch pedal arm side, reduce abnormal sound, improve driver comfort.
3, because protecting sleeve adopts the polyurethane betrothal gifts, so wear resisting property is good, and manufacturing processing technic is simple.
