The specific embodiment
The present invention is relevant a kind of oil-pressure caliper driving device, please referring to figs. 1 through shown in Figure 3, comprises a cover body 10, at least one elastic component 20 and at least one adapter plate 30, wherein:
This cover body 10 is provided with at least one circular open room 11, in order to ccontaining this elastic component 20 and this adapter plate 30; Most preferred embodiment is that cover body 10 is provided with disymmetrical room 11, and respectively a ccontaining elastic component 20 and an adapter plate 30, and present embodiment is with explanation one of in two rooms 11;
This cover body 10 is provided with a passage 12, and this passage 12 is located at the side of cover body 10, and in order to be communicated with an oil pipe and room 11, this cover body 10 is provided with several first holes 13 in its side, and extends into this room 11;
This elastic component 20 is to be installed in this cover body 10, and this elastic component 20 is processed for circle and by the rubber material, and this elastic component 20 is to be installed in hermetically and with one heart in the room 11, in order to seal room 11 with ccontaining Brake fluid; This elastic component 20 has a side 21, and this side 21 is by the periphery horizontal expansion, and contacts with the inner peripheral surface of room 11; This elastic component 20 has a protuberance 22, and this protuberance 22 forms in the center of elastic component 20, and joins with a brake shoe; This elastic component 20 has a U-shaped portion 23, and this U-shaped portion 23 forms between side 21 and the protuberance 22, and the thickness of this protuberance 22 is for big than elastic component 20 other parts; In order to prevent protuberance 22 distortion, when initial state, U-shaped portion 23 is by the elastic force shape that holds its shape; When stressed, U-shaped portion 23 produces deformation, in order to the displacement of protuberance 23 displacements to be provided; This elastic component 20 has an annular flange flange 24, and this flange 24 is adjacent with side 21, and vertical and extend internally by the tail end of side 21;
This adapter plate 30 is to be installed between this cover body 10 and this elastic component 20, and this adapter plate 30 is circular, and this adapter plate 30 has a shoulder 31; This shoulder 31 forms in its outer peripheral face, and corresponding with the annular flange flange 24 of elastic component 20, in order to fixing elastic component 20; This adapter plate 30 has several perforation 32; Pass through in order to Brake fluid in order to the passage that is communicated with cover body 10 12, this adapter plate 30 has several second holes 33, and this second hole 33 is corresponding with first hole 13 of cover body 10.
During assembling, several connecting elements 40 are passed cooresponding first hole 13, then with the locking of corresponding second hole, in order to fixedly adapter plate 30 and elastic component 20, this shoulder 31 and corresponding cyclic flange 24 matching and fixing elastic component 20 in room 11.
Oil-pressure caliper driving device of the present invention is in initial condition, sees also shown in Figure 3ly, inserts Brake fluid between elastic component 20 and the adapter plate 30.Continuous see also shown in Figure 4, when the user operates brake handgrip, the oil pressure rising between elastic component 20 and adapter plate 30; And during greater than the elastic force of elastic component 20, the protuberance 22 of elastic component 20 receives the oil pressure effect, is pushed to brake shoe; Reaching the brake purpose, but because the deformation behavior of U-shaped portion 23, U-shaped portion 23 produces deformation; So that the variation of protuberance 23 displacements to be provided, and because the rigidity of protuberance 22 can provide an even strength to brake shoe.When discharging brake handgrip, oil pressure reduces, and receives the effect of elastic force, and U-shaped portion 23 and protuberance 22 return back to initial condition, does not therefore also have the brake of providing strength.
The present invention is simple in structure, and number of components is few, and the cost of not only processing and making reduces, and promotes product competitiveness greatly, and more because piston is not set, overall volume is littler thinner, thereby reduces the risk that the collision generation damages.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
