[0006] The axis assembly includes a shaft rod, and the two ends of the shaft rod are respectively provided with a first thread and a second thread, a fixing piece is provided on the front side of the second thread, and the fixing piece is arranged on the shaft rod, a DU bearing 1 is provided on the side of the fixing piece away from the second thread, and a DU bearing 2 and a DU bearing 3 are also provided on the side of the shaft rod away from the DU bearing 1, and DU bearing 2 and DU bearing 3 are simultaneously arranged at the two ends inside the support sleeve, a stop washer is provided on the side of the DU bearing 3 away from the DU bearing 2, and a shock-absorbing washer is provided on the side of the stop washer away from the DU bearing 3, and the stop washer and the shock-absorbing washer are both sleeved on the shaft rod.

[0007] As a preferred embodiment of the utility model, a nut is detachably provided on the first thread, and the stop washer and the shock-absorbing washer are disposed between the nut and the DU bearing three.

[0008] As a preferred embodiment of the present invention, the outer wall of the DU bearing 1 fits with the inner wall of the mounting hole, and the outer wall of the support sleeve also fits with the inner wall of the mounting hole.

[0009] As a preferred embodiment of the present invention, the support sleeve material is reinforced engineering plastic.

[0010] As a preferred embodiment of the present invention, the support sleeve can be filled with butter.

[0011] As a preferred embodiment of the present invention, the top of the plastic pedal body is provided with anti-slip grooves.

[0012] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0013] 1. The utility model greatly increases the effective matching area between the support sleeve and the plastic pedal body by coordinating the support sleeve with the DU bearing two and the DU bearing three, thereby greatly increasing the load force of the plastic pedal body, ensuring the stability and continuous use of the pedal during use, and preventing the loosening of the matching parts when the DU bearing and the plastic pedal body are in direct contact.

[0014] 2. The utility model provides an oil storage function in the middle part of the support sleeve DU bearing 2 and DU bearing 3, which greatly increases the lubrication effect between the axis and the bearing, thereby increasing the service life of the product.

[0015] 3. The utility model provides a stop washer on the axis to prevent the fixing nut at the first threaded end from loosening and falling off during use of the product, thereby increasing safety.

[0016] 4. The utility model can increase friction by arranging anti-skid patterns on the main body of the plastic pedal, thereby preventing the sole and the main body of the plastic pedal from slipping during riding, thereby increasing safety. BRIEF DESCRIPTION OF THE DRAWINGS
