Abstract
The utility model discloses an impact-resistant, high load ratio wheel, including dismantling the wheel hub body and half wheel hub of connection, connect the holistic appearance face bilateral symmetry of back wheel hub body and half wheel hub, its symmetry axis and the coincidence of tire central line. The airplane wheel can effectively improve the load ratio of the airplane wheel and reduce the weight of products.
Description
Technical Field
The utility model belongs to the technical field of the aircraft wheel, especially, relate to an impact-resistant, high load ratio wheel.
Background
The airplane wheel is mainly used for taking off, landing, supporting and running of the airplane. When the airplane lands on the ground, the wheels are required to bear impact load without damage, and particularly when the helicopter crashes, the wheels are required to bear crash-resistant load so as to ensure the energy-absorbing integrity of the whole landing gear system and reduce or avoid the damage of pilots.
The requirement on the weight of the conventional airplane wheel product is not strict, the airplane wheel structure generally adopts an offset structure or a single-web structure, and the impact load requirement can be met by adopting 2A50 aluminum alloy or 2A14 aluminum alloy as a main bearing part hub of the airplane wheel. However, with the development of the aviation aircraft technology, the requirement of higher load ratio on the aircraft wheel is met, and the requirements of impact load and weight cannot be met by the conventional aircraft wheel structure and the hub material, so that the development requirement of the field of the aircraft wheel is not met.
SUMMERY OF THE UTILITY MODEL
Purpose of the utility model
In order to solve the problem, the utility model provides an impact-resistant, high load ratio wheel, wheel structure adopt the symmetry to open, "A" type web structure, and the wheel hub material adopts injection moulding 7055 aluminum alloy forging. The loading ratio of the airplane wheel can be effectively improved, and the weight of the product is reduced.
Technical solution of utility model
The impact-resistant wheel with high load ratio comprises a hub body and a half hub which are detachably connected, the overall external surface of the hub body and the half hub after being connected is symmetrical left and right, and the symmetry axis of the wheel is superposed with the central line of a tire.
Preferably, the hub web is angled equally with respect to the tire centerline and the half hub webs are angled equally with respect to the tire centerline.
Preferably, the hub body and the half hub are both made of 7055 aluminum alloy through injection molding.
Preferably, the hub body and the half hub are detachably connected by bolts and self-locking nuts.
Preferably, a sealing ring is arranged between the hub body and the half hub.
Preferably, tapered roller bearings are arranged in the bearing holes of the hub body and the half hub.
Preferably, the half hub is provided with an inflation nozzle assembly.
The utility model has the advantages that: the airplane wheel can effectively improve the load ratio of the airplane wheel and reduce the weight of products.
Drawings
Fig. 1 is a schematic structural view of an impact-resistant high-duty-ratio wheel.
Fig. 2 is a structural schematic diagram of an A-shaped web.
In the figure: 1-hub body, 1 a-hub body web plate, 2-bolt, 3-sealing ring, 4-self-locking nut, 5-half hub, 5 a-half hub web plate, 6-tapered roller bearing and 7-inflation nozzle component.
Detailed Description
The utility model discloses a realize through following technical scheme.
The utility model provides an impact-resistant, high load ratio wheel, includes wheel hub body 1, bolt 2, sealing washer 3, auto-lock nut 4, half wheel hub 5, tapered roller bearing 6, aerifys and chew subassembly 7, and tapered roller bearing 6 installs in the bearing hole of wheel hub body 1 and half wheel hub 5. The inflation nozzle assembly 7 is mounted on the half hub 5.
For the load ratio who improves the wheel, the wheel adopts the symmetry to open structure, and concrete structure is: the wheel hub body 1 and the half wheel hub 5 are connected through the bolt 2 and the self-locking nut 4 to form an integral structure with symmetrical appearance, a symmetrical shaft is superposed with the end face of one end of the wheel hub body 1 connected with the half wheel hub 5, the symmetrical shaft is a symmetrical center line of the wheel, and the symmetrical center line of the wheel is superposed with the center line of the tire.
For lightening the weight of the product, the web plate of the airplane wheel adopts an A-shaped web plate structure, and the specific structure is as follows: the hub body web 1a and the half hub web 5a are at the same angle to the wheel symmetry center line.
In order to improve the load ratio of the airplane wheel and increase the impact resistance of the airplane wheel, the hub body 1 and the half hub 5 are machined by 7055 aluminum alloy forged pieces formed by injection molding.
