This utility model compared with the existing technology, with reference to FN calipers and the structural advantage of FN3 calipers, brand-new design Function enhancement mode FN+ floating brake caliper, on the one hand retains the outside friction disc locating surface of FN caliper shells, makes FN+ calipers exist Show in terms of noise excellent；On the other hand, optimize the length of outside friction disc locating surface on FN+ housings, need machine to add script whole The locating surface of individual housing bridge minister's degree is changed to may insure the length of function, saves machining productive temp, while obtaining The wider case width of relative FN caliper shells, and then the casing rigidity for having relative FN3 calipers higher, make FN+ systems Dynamic tonger has good pedal sense, effectively suppresses eccentric wear and drags the generation of problem.Housing has in the size of circumferential width Larger increase, while intensity is improved, creates bigger space in the increase of width to support and friction plate, enters And areal of friction facing also increases accordingly, bigger areal of friction facing can with temperature when re-absorption equal heat quantity raise compared with It is low, be conducive to the stable of coefficient of friction and reduce abrasion.

Description of the drawings

Fig. 1 is this utility model structural representation.

Fig. 2 is this utility model Structure explosion diagram.

Referring to Fig. 2,1 is housing, and 2 is support, and 3 is guide finger, and 4 is buffer ferrule, and 5 are protection plug, and 6 is bleeder screw, 7 For dust cap, 8 is piston, and 9 is sealing ring, and 10 is dust cover, and 11 is screw thread protecting plug, and 12 is that housing keeps spring, and 13 is interior Friction plate, 14 is outside friction disc, and 15 is contiguous block.

Specific embodiment

This utility model is described further below according to accompanying drawing.

Such as Fig. 1, shown in Fig. 2, the front side of support 2 connects outside friction disc 14, the inner side connection inner attrition piece 13 of support 2, shell The cylinder holes end connection dust cover 10 of body 1, and housing 1 connects piston 8 by dust cover 10；Described housing 1 is located at support 2 Outside, and housing 1 is using guide finger 3, buffer ferrule 4 and protects plug 5 to be connected with support 2；Positioned at the front side connection shell of housing 1 Body keep spring 12, and housing keep spring 12 fixing end be connected with housing 1, housing keep spring 12 left and right two ends and Support 2 connects；One end of bleeder screw 6 is provided with positioned at the side of the cylinder head of housing 1, the other end connection of bleeder screw 6 is dust-proof Cap 7.

The width of housing 1 is 173mm, and the upper end of housing 1 is in arc-shaped structure, and before and after the lower end of housing 1, both sides connect respectively Two contiguous blocks 15 are connect, the central authorities of contiguous block 15 are provided with through hole.

The width of support 2 is 227mm, and support 2 is C font structures.

The width of outside friction disc 14 is 181.3mm, and the upper end of outside friction disc 14 is in arc-shaped structure, under outside friction disc 14 End is in flat shape structure.

Guide finger 3, buffer ferrule 4 and protection plug 5 are provided with two groups, respectively positioned at housing 1 cylinder head left and right sides position.

Housing 1 positioned at 6 side of bleeder screw is provided with screw thread protecting plug 11.

Housing 1 has larger increase in the size of circumferential width, and 1 intensity of housing is further strengthened, and makes FN+ brake tonger There is good pedal sense, effectively suppress eccentric wear and drag the generation of problem.

For the housing 1 of match width increase, the size of 14 backboard of support 2 and outside friction disc also accordingly can increase, from company Satisfactory larger width dimensions series, the broaching tool of each dimension series are chosen in standardization, the size specification of seriation The overall dimension all standardization of groove correlation determine, can use same machining equipment in the machine added-time, subtract in certain degree Lack the input of equipment, reduce the machine addition sheet of product.

Housing 1, support 2, the increasing of 14 carupace width size of outside friction disc, make 14 area of outside friction disc also increase accordingly Greatly, for comparing tradition with cylinder diameter caliper, the areal of friction facing of FN+ calipers increases about 30% or so.Bigger friction plate Area, less drag friction heat, the brake disc temperature under frequent damped condition will not be too high, and the coefficient of friction heat of caliper declines Move back that phenomenon is not obvious, be conducive to the stable of coefficient of friction and reduce abrasion.

Retain the outside friction disc locating surface that traditional braking clamps housing, optimize the length of outside friction disc locating surface on FN+ housings, Need machine to add the locating surface of whole housing bridge minister's degree to be changed to may insure the length of function script, save machining life Beat is produced, production efficiency is improve.
