Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1-5, a spring suspension for a scooter comprises a main suspension 2 connected with the end of a scooter 1, two upper support arms 3, two lower support arms 4 and a shock absorber 5, wherein the left and right ends of the middle part of the main suspension 2 are respectively hinged with one end of the upper support arm 3, and the other end of the upper support arm 3 is connected with a wheel 6; the left end and the right end of the lower part of the main suspension 2 are respectively hinged with one end of a lower support arm 4, and the other end of the lower support arm 4 is connected with a wheel 6; the position of the lower support arm 4 close to the wheel 6 is hinged with one end of a shock absorber 5, and the other end of the shock absorber 5 is hinged with the upper part of the main suspension 2; the included angle between the upper support arm 3 and the surface of the sliding plate 1 is larger than 0 degree and smaller than 90 degrees, and the included angle allows the spring suspension to integrally rotate.

A suspension bracket 7 is hinged above the main suspension 2, and the suspension bracket 7 is connected with the sliding plate 1.

The whole C shape that is of

suspension bracket

7, 2 upper ends of main suspension are located suspension bracket 7, and main suspension 2 is connected through the both ends of pivot with suspension bracket 7, are equipped with blotter 8 between 2 up end of main suspension and the suspension bracket 7, the power between buffer plate face and the spring suspension.
