Abstract

The utility model discloses a braking disk pair for aircraft landing gear. The braking disk pair comprises three dynamic disk components, two static disks, a compressing disk and a pressure bearing disk, wherein, one compressing disk, one dynamic disk component, one static disk, one dynamic disk component, one static disk, one dynamic disk component and one pressure bearing disk are orderly stacked; each dynamic disk component comprises a dynamic disk and steel clips; nine outer key slots are arranged on each dynamic disk; two ends of each outer key slot are respectively in rivet connection with the steel clips; the outer key slots are matched with convex keys on a wheel hub and rotate together with aircraft wheels in brake loosening process; the static disks and the compressing disk are respectively provided with twelve inner keys which are matched with concave keys on a braking shell to transmit torque in braking process; twelve circular grooves are arranged on the non-friction surface of the pressure bearing disk, which are matched with a pressure bearing cup on the braking shell to transmit torque in braking process.

Description

Undercarriage braking brake dish pair

Technical field

The utility model patent relates to a kind of brake disc pair, relates in particular to a kind of undercarriage braking brake dish pair.

Background technique

Destroying Hong seven A aircrafts is fighters of Chinese development and production, the secondary function of the C/C material of this aircraft brake be guarantee aircraft in ground taxi, turning, normal landing, landings of taking off, overload, end to take off and the skidding when ground stop and engine test.

Summary of the invention

In order to realize above-mentioned functions, the utility model is achieved through the following technical solutions:

Undercarriage braking brake dish pair comprises three dynamic disk components, two quiet dishes, a compression plate and a bearing disc, and compression plate, dynamic disk component, quiet dish, dynamic disk component, quiet dish, dynamic disk component, bearing disc laminate in proper order.

Described dynamic disk component comprises Moving plate and steel folder, and 9 outside keyways are arranged on the Moving plate, and the steel folder is riveted at each outside keyway two ends respectively, and outside keyway cooperates with protruding key on the wheel hub, rotates with wheel when getting off the brakes.

Transmitting torque when described quiet dish, compression plate all have 12 internal keies to cooperate brake with brake housing fovea superior keyway.

There are 12 circular grooves to cooperate transmitting torque during brake on the described bearing disc non-rubbing surface with the pressure-bearing cup of brake on the housing.

The utility model can make brake disc rubbing contact area reach maximum, reduces the contraction deformation of brake disc, improves braking efficiency.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further, but not as to qualification of the present utility model.

As shown in Figure 1, undercarriage braking brake dish pair comprises the quiet dish of three dynamic disk components 2, two 3, a compression plate 1 and a bearing disc 4, and compression plate 1, dynamic disk component 2, quiet dish 3, dynamic disk component 2, quiet dish 3, dynamic disk component 2, bearing disc 4 orders laminate.

As Fig. 2～shown in Figure 6, dynamic disk component 1 comprises Moving plate 5 and

steel folder

6, and 9 outside keyways 7 are arranged on the Moving plate 1, and steel folder 6 is riveted at each outside keyway 7 two ends respectively, outside keyway 7 cooperates with protruding key (not shown) on the wheel hub, rotates with the wheel (not shown) when getting off the brakes.

As Fig. 7～shown in Figure 8, quiet dish 3, compression plate 1 all have 12 internal keies 8, cooperate transmitting torque when braking with brake housing fovea superior keyway (not shown).

As shown in Figure 9, bearing disc 4 has 12 circular grooves 9 and the pressure-bearing cup (not shown) of brake on the housing) cooperate transmitting torque during brake.

Manufacture method is: buy the charcoal fiber, and the self-control precast body, vapor deposition, resin impregnation curing, charing processing, graphitization processing, machining and inoxidzable coating processing become the disc type brake disc pair.

Specific embodiment of the present utility model elaborates content of the present utility model.For persons skilled in the art, any conspicuous change of under the prerequisite that does not deviate from the utility model spirit it being done all constitutes the infringement to the utility model patent, with corresponding legal responsibilities.
