Detailed Description

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

Fig. 1, fig. 2, fig. 3 and fig. 4 show a three-dimensional explosion diagram and an installation diagram of a double-sided disc brake of a scooter of the invention, the whole disc brake is installed on an installation frame 13, a fixing screw 14 passes through two through holes of the installation frame 13 to be fixed with a sliding sleeve nut 11, the sliding sleeve nut 11 is sleeved in two sliding sleeve holes 1.1 on a large caliper body 1, the sliding sleeve holes 1.1 are parallel to the axis of a main ejector rod 3, the sliding sleeve holes 1.1 are circular or non-circular geometric holes with equal cross-sectional areas, and the sliding sleeve holes 1.1 and the sliding sleeve nut 11 are in sliding fit with a small gap. A rubber ring, a plastic sheet, a spring piece or a friction material is added between the sliding sleeve nut 11 and a gap of a sliding sleeve hole 1.1 of the large plier body 1, so that non-resettable friction resistance is increased, and follow-up positioning is carried out; in order to adapt to different sizes, the sliding sleeve nuts 11 and the mounting rack 13 are adjusted by adding or subtracting gaskets or sliding sleeve nuts 11 with various lengths and lengths; the shape of the sliding part of the sliding sleeve nut 11 is adapted to the shape of the sliding sleeve hole 1.1 of the large caliper body 1. Such a mounting method illustrates that the entire disc brake is slidable perpendicular to the disc 17. When the double-sided disc brake acts, the disc 17 is arranged in the middle position, and the problem of disc rubbing is avoided.

When the steel wire drives the bridge type pull rod 7 to rotate, the auxiliary ejector rod 4 and the main ejector rod 3 are driven to rotate, under the action of the auxiliary steel balls 15, the main steel balls 16, the auxiliary ejector rod cover 6 and the main ejector rod cover 5, the auxiliary ejector rod 4 and the main ejector rod 3 are ejected out in an opposite direction, the auxiliary wheel 9 and the main wheel 8 are pushed to the friction plate 10 in an opposite direction, and the friction plate 10 brakes the disc 17.
