Brief description of the drawings
Fig. 1 is explosive view of the invention.
Fig. 2 is positive structure schematic of the invention.
Fig. 3 is the structural representation at the back side of the present invention.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-3, a kind of band type brake for bicycle formula roller brake gear, including shell 2, support 3, brake rim 4, roller
Retainer 5, brake block 6, roller 7, cam ring 9 and bonnet 10, the shell 2 and support 3 are fixed on roller by lock-screw 1
On retainer 5, the roller cage 5 is located at the left side of support 3, and support 3 is located at the left side of shell 2, and the left side of support 3 is provided with
Multiple protrusions 14, the brake rim 4 is located at most inner side and can freely rotated, and brake block 6 is located at brake rim 4 and roller is kept
Between frame 5, and the inner side of brake block 6 is contacted with brake rim 4, and outside is contacted with roller 7, and cam ring 9 is enclosed on roller cage 5
Outside and its inner side contacted with roller 7, roller 7 is positioned in roller cage 5, inside and outside roller 7 respectively with brake block 6
Contacted with cam ring 9, while stop that brake block 6 is used when brake block 6 plays brake by the protrusion 14 of support 3, the convex
Wheel 9 is connected by tension disc 11 and steel cable lock-screw 12 with brake cable, and returning spring 8 is located between cam ring 9 and support 3,
One end is buckled in one end on cam ring 9 and is buckled on support, replys release action after playing brake, the bonnet 10 passes through lock-screw
1 is fixed on the left side of roller cage 5, and such bonnet 10 and shell 2 protect roller inner body not fall off together.
The flower-drum axis of bicycle passes through the interstitial hole 13 of support 3, the inner side of bicycle drive shaft and the knot of brake rim 4
Close；The inner side of the brake rim 4 is straight trough spline 17 or internal thread, straight trough spline 17 or internal thread that brake rim 4 passes through inner side
With flower-drum connection.The support 3 also links together with the lower fork locking of bicycle；Three branch are additionally provided with the support 3
