Define.
As shown in Figures 1 to 4, the main modulation mechanism of a kind of disk brake, including shift fork axle 1, gear 2 and adjustment lid 3,
The gear 2 is sleeved in shift fork axle 1, and the adjustment lid 3 is sleeved on the lower end of shift fork axle 1.The gear 2 has teeth portion 21
With axle portion 22, sleeve 4 is set on the lower end of the axle portion 22 of gear 2.The inside of the adjustment lid 3 has by 32 groups of multiple ball-and-sockets
At flower pattern chamber 31, be equipped with steel ball 5 in the ball-and-socket 32 of the flower pattern chamber 31.In the present invention, steel ball 5 in flower pattern chamber 31
Quantity is two, which is symmetrical set.Volute spring 6, steel ball 5 and volute spring are also equipped in the flower pattern chamber 31
6 contacts.The lower end of the sleeve 4 is extend into the flower pattern chamber 31 of adjustment lid 3, and the lower end of the sleeve 4 is with downwardly open
Fluting, the quantity of fluting are two.A part of steel ball 5 in ball-and-socket 32 is embedded in again in the fluting of sleeve 4, the sleeve 4
It is outer to be set with Rectangular Spring 7 again, it is set with cylindrical spring 8 again outside Rectangular Spring 7.The top of Rectangular Spring 7 and cylindrical spring 8
Top is sleeved on outside gear 2.
In the present invention, gear 2 is mounted on a bracket 9.Specifically, the middle part of the bracket 9 has a mounting hole,
The axle portion 22 of gear 2 is threaded through in the mounting hole of bracket 9.The teeth portion 21 of gear 2 is located at the top of the mounting hole of bracket 9.In addition,
