Abstract
The utility model relates to a pair of brake calipers which comprises a caliper body and two friction plates, wherein two groups of piston holes are arranged on the caliper body; pistons are arranged in the piston holes; the two friction plates are respectively connected with the pistons in the two groups of piston holes; an oil path which is connected with the piston holes in series is further arranged on the caliper body; an oil inlet and an air exhaust are arranged in the oil path; and the oil inlet and the air exhaust are respectively arranged at the two ends of the oil path; the oil path is communicated with air from front to back; hydraulic oil enters from the oil inlet and exits from the air exhaust, so that the air in the oil path is exhausted conveniently, dead points are avoided, all pistons can pass in and out freely and move in an orderly way, and the phenomenon that the friction plates are inclined so as to cause contact stagnation with a brake disc during the braking can be avoided; in addition, due to the layout that the oil inlet and the air exhaust are uniformly and symmetrically arranged at the two ends of the oil path, the running direction of an oil pipe can be changed freely, namely, the positions of the oil inlet and the air exhaust can be exchanged.
Description
Technical field
The invention belongs to the hydraulic brake technical field, especially belong to electric motor car hydraulic disc brake caliper field, relate to a kind of brake calipers concretely.
Background technique
The electric motor car hydraulic disc brake caliper promotes friction plate through the hydraulic oil driven plunger and clamps brake disc realization electric motor car braking, wherein, provides the structure of the oil circuit of hydraulic oil to have direct related with the braking effect of brake calipers for piston.In the electric motor car hydraulic disc brake caliper, each friction plate all by two pistons cooperation carrying out ejections, is connected each piston hole through oil circuit; Be convenient to like this each piston is carried out synchronization control to reach braking effect preferably, can get into each piston hole driven plunger smoothly, just exhaust port need be set on oil circuit in order to make hydraulic oil; But in the existing technology (as shown in Figure 1), the oil circuit of brake calipers structurally also comes with some shortcomings: exhaust port on the oil circuit and filler opening are arranged on a side of single friction plate; This structure is when dashing oil to oil circuit; The exhaust of oil circuit is not smooth, can form dead point (X, Y place among the figure) at the two ends of oil circuit, hinders hydraulic oil and gets into the piston hole that is positioned at the oil circuit back segment smoothly; Not only can cause moving of piston synchronous inadequately; Can make that also the piston that is positioned at the oil circuit rear end does not have enough ejection forces, and then cause the braking force of friction plate inclination and brake calipers less, influence the braking ability of brake calipers.
The model utility content
The utility model technical problem to be solved is to provide a kind of braking ability preferable brake calipers.
For solving the problems of the technologies described above; Realize above-mentioned technique effect, the technological scheme that the utility model provides is: a kind of brake calipers, and it comprises caliper and two friction plates; Described caliper is provided with two groups of piston holes; Be provided with piston in the described piston hole, described two friction plates respectively with two groups of piston holes in piston be connected, also be provided with on the described caliper series connection each piston hole oil circuit; Described oil circuit is provided with filler opening and relief opening, and described filler opening and relief opening lay respectively at the two ends of oil circuit.
After adopting above technological scheme, compared with prior art, the advantage of the utility model is: equal and air communication before and after this oil circuit; Hydraulic oil gets into from oil inlet hole, comes out from vent hole at last, makes things convenient for the air in the oil circuit to discharge; Avoid the appearance at dead point; It is free to help the turnover of each piston, and moving of each piston is comparatively neat, the inclination of friction plate in the time of can avoiding braking and dragging with contacting of brake disc; Because oil inlet hole and vent hole are arranged on the layout at oil circuit two ends symmetrically, can arbitrarily change the oil pipe trend according to customer requirement in addition, promptly oil inlet hole and vent hole can exchange.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As shown in Figure 2; The utility model brake calipers; It comprises caliper 1 and two friction plates 2, and caliper 1 is made up of two-part, i.e. caliper a and caliper b; Two groups of piston holes 3 on the caliper 1 are separately positioned on caliper a and the caliper b; Be equipped with in each piston hole 34, two friction plates 2 of piston through respectively with two groups of piston holes 3 in piston 4 ways of connecting be installed on caliper a and the caliper b, also be provided with the oil circuit 5 of each piston hole 3 of connecting on the caliper of forming by caliper a and caliper b 1; Oil circuit 5 is provided with filler opening 6 that supplies the hydraulic oil circulation and the relief opening 7 that is used to discharge oil circuit 5 air, and the joint of the oil circuit 5 on caliper a and caliper b is provided with O RunddichtringO 8 and carries out encapsulation process.
Be full of oil circuit 5 for what make that hydraulic oil can be smooth, balanced; Described filler opening 6 and relief opening 7 lay respectively at the two ends of oil circuit 5, and in this example, the piston hole 3 on the oil circuit 5 one caliper a is a starting point; Be communicated with two piston holes 3 on the caliper b successively; Another piston hole 3 on last and the caliper a is communicated with and gets final product, and filler opening 6 is positioned at the starting point place of oil circuit 5 on the caliper a, and relief opening 7 is positioned at the terminal position place of the last oil circuit 5 of caliper a.
