Relatively small, the spacing between left and right bearing assembly 4 is 100mm, and bearing assembly 4 is between chain drum 5 and brake assemblies 3, axis
Bearing assembly 4 and the tie point distance of rear axle 1 are shorter than the distance between rear axle 1 and tire, therefore tire is generated in emergency braking
Inertia force need to be transmitted to bearing assembly 4 by 5 weld of chain drum, then be transmitted to vehicle body, be easy to cause rear axle 2 in chain in this way
The distortion of 5 weld of disk or fracture.
In order to guarantee the durability of rear axle 2, the diameter of setting rear axle 2 is 25mm, the bearing group positioned at 1 left and right sides of rear axle
Spacing between part 4 is 225mm, and then shortens bearing assembly 4 the distance between of the tire to rear axle 2, tyre emergency braking
When the inertia torsion that generates rear axle 1 has completely been transmitted to directly from bearing again to vehicle body, the junction of rear axle 1 and rear axle 2
In 3 outside of chain drum 5 and brake assemblies, effectively avoids torsion transmitting between tire and rear axle 1 and need by 5 pad of chain drum
Drawback, to effectively ensure the fastness and resistance to pressure of rear axle 2.
The utility model additionally provides a kind of sandy beach motor, and any of the above-described rear axle assy is had on the sandy beach motor.
When in use, which is mounted on the motor of sandy beach, the durability of sandy beach motor rear axle can be improved.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
