When the jockey needed brake bicycle, the brake handle of holding with a firm grip, bicycle began brake.When the speed of bicycle was slow, the brake of bicycle operation mainly contained following three kinds of situations:
One. when position (such as Fig. 5) in open slot 22 scopes, the position of the pad 1 of bicycle, because pad 1 does not contact with braking disc 2, bicycle does not brake; Through the motion of short time, pad 1 beginning contacts with braking disc 2, and the motion conditions of its back is identical with the second motion conditions described below;
Two. when the pad 1 of bicycle between open slot 22 and the braking district 21 and to the direction operation (such as Fig. 6) in braking district 21 or within brake area when (such as Fig. 7), pad 1 contacts with braking disc 2, the positive pressure of pad 1 produces friction force, bicycle is braked, because bicycle speed is slow, so very fast braking is identical with original brake gear, does not have the effect of a little stopping.This meets the needs of brake, need not a little to stop because speed is slow;
Three. when the pad 1 of bicycle moves (such as Fig. 8) between open slot 22 and braking district 21 and to the direction of open slot 22, if its braking force deficiency is so that during the bicycle stop motion, braking disc 2 slightly has rotation, when forwarding pad 1 to above open slot 22, motion conditions thereafter is identical with the first situation recited above.
, needs fast when the speed of bicycle are put in a flash, and the point of bicycle is stopped and mainly comprised following 3 processes:
When 1, the pad 1 of bicycle was positioned at the scope (such as Fig. 5) of open slot 22, because two pads 1 do not contact with braking disc 2, bicycle did not brake; Through the motion of short time, pad 1 beginning contacts with braking disc 2, enters into process 2;
2, the pad 1 of bicycle moves (such as Fig. 6) between open slot 22 and braking district 21 and to the direction in braking district 21, and pad 1 contacts with braking disc 2, and the positive pressure of pad 1 produces friction force, and bicycle is braked.Because the braking force deficiency is so that during the bicycle stop motion, braking disc 2 slows down and rotates, braking disc 2 turns to position as shown in Figure 7, continues to slow down to forward to, enters process 3;
3, the pad 1 of bicycle moves (such as Fig. 8) between open slot 22 and braking district 21 and to the direction of open slot 22, and bicycle continues to slow down and rotates, until enter process 1.
The present invention finishes the judgement (according to the speed of the speed of a motor vehicle) that common brake and point are stopped, and finishes automatic point and stop by braking disc 2 and the pad 1 of the novel bicycle of design.The starting point that point is stopped can begin by the arbitrary process in 3 processes, until bicycle stops fully, puts the end of stopping.
Adjust the length of open slot, the length of brake area can be finished the adjustment of the distance of a little stopping (namely in a flash between).
The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
