The specific embodiment
See also Fig. 1 shown in shown in Figure 3, the disc brakes device 1 that the present invention's first preferred embodiment is provided consists predominantly of a pedestal 10, a brake disc 20, two brake arm 30a, 30b, two brake facings 35, a tension control assembly 40, a location device 50 and a brake cable 60, wherein:
Each brake arm 30a, 30b respectively have an articulated section 31 and a brake bar 32.One axostylus axostyle 33 passes two brake arm 30a, and the articulated section 31 of 30b is locked in the axis hole 11 of pedestal 10 again, and so as to making two brake arm 30a, 30b is hubbed on the pedestal 10, and has identical pivot axle center, but can independently swing again.Two brake arm 30a, 30b lay respectively at two sides of brake disc 20, and depart from brake disc 20 centers one segment distance.Two brake facings 35 are fixedly arranged on respectively in the brake bar 32, in the face of two sides of brake disc 20, and are positioned at the appropriate location of departing from brake disc 20 centers one preset distance.In principle, two brake facings 35 should be tried one's best near the periphery of brake disc 20, and preferable brake ability so can be provided.
One end of brake cable 60 is connected to a brake handgrip (not shown), the other end passes a brake arm 30a and utilizes a screw 61 to be locked in another brake arm 30b, whereby, the user can drive two brake arm 30a by pushing the brake handgrip, and 30b is towards brake disc 20 swings.
See also shown in Figure 4ly, under initial condition, that is under the state that is not pulled of brake cable 60, because the effect of registration device 50, two brake arm 30a can keep a suitable angle between the 30b, and two brake facings 35 are not contacted with brake disc 20.
Fig. 5 shows that brake cable 60 is pulled, and orders about two brake arm 30a, and 30b makes two brake facings 35 compress brake disc 20 and the effect of generation brake towards brake disc 20 swings.
When the adjustment screw rod 41 of tension control assembly 40 is rotated, and when the direction of compression spring 42 moves, can cause compression spring 42 to be compressed and produce bigger elastic force, and make brake cable 60 must provide bigger pulling force just to drive two brake arm 30a, 30b, otherwise, be rotated when adjusting screw rod 41, and during away from compression spring 42, the elastic force of compression spring 42 is reduced, so, brake cable 60 provides less pulling force can spur two brake arm 30a, 30b.
Fig. 6 is the disc brakes device 2 that shows that the present invention's second preferred embodiment is provided, its keystone configuration is identical with first embodiment, include a pedestal 71, a brake disc 72, two brake arm 73a, 73b, two brake facings 74, location device 76, a tension control assembly 75 and a brake cable 77, difference is that two brake arms 73 have pivot axle center 78 separately respectively, 79, and two pivot axle center 78,79 are that level is arranged side by side.Two brake arm 73a provided herein, the reason that 73b has the axle center 78,79 that self independently pivots is: as brake cable 77 pullings two brake arm 73a, during the 73b swing, be actually and drive the brake arm 73b that is positioned at brake disc 72 inboards earlier, then just can drive the brake arm 73a in the outside, therefore, two brake arm 73a, the action of 73b has some difference.The two brake arm 73a with different pivots axle center 78,79 that second embodiment is provided, 73b can make two brake arm 73a, 73b have independently swing state, and braking effect is more improved.
The disc brakes device 3 of the third embodiment of the invention that Fig. 7 is shown, its keystone configuration is identical with second preferred embodiment, but, two brake arm 73a ', the independently pivot axle center 78 ', 79 ' that 73b ' had is side by side vertical.
Fig. 8 is the disc brakes device 4 of the present invention's the 4th preferred embodiment, one pedestal 81, a brake disc 82, two brake arms 83, two brake facings 84, location device 86, a tension control assembly 85 and a brake cable 87, wherein 831 rear respectively has an extension arm 832 to two brake arms 83 in the articulated section, and brake cable 87 is to be connected in two extension arms 832, so also can reach and the aforementioned structure identical functions.
The invention has the advantages that: simple structure can not produce the untrue situation of brake. Therefore, it is lower that disc brake provided by the present invention mechanism has a cost, can be applicable to bicycle etc. On the lower vehicles of price.
