System, is one of main component of aircraft.But if meeting aircraft landing site to be covered by heavy snow, aircraft can not just be risen
Drop is so as to cause influence economically.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of Fixed Wing AirVehicle for installing additional and folding sled
Fall frame.
The utility model adopts the following technical solution: a kind of Fixed Wing AirVehicle undercarriage installing folding sled additional, including
Undercarriage ontology, tire, ski device, rotating device, tire is located at undercarriage body bottom portion, between tire and undercarriage ontology
It is attached by axis, ski device is symmetrically distributed in undercarriage ontology two sides, and rotation is equipped between ski device, undercarriage ontology
Rotary device；
The ski device includes sled, rotary support, and rotary support is set to sled indent side, and the rotary support is used
In carrying out rotary folding to sled, rotate sled to undercarriage ontology two sides, the rotating device includes main rotating shaft, secondary rotation
Shaft, secondary rotary shaft connect with vertical member one end axis, and the vertical member other end is fixedly mounted in rotary support, main rotating shaft with
Rod piece one end axis connects, and the rod piece other end is fixedly connected on undercarriage ontology, passes through liquid between the main rotating shaft, secondary rotary shaft
Strut Part is fixedly connected, and the rotating device is for rotating sled to undercarriage body bottom portion, rotary support and rotating device
It cooperates and can be realized the enabling and disabling of sled.
The utility model has the advantage that: installing the Fixed Wing AirVehicle undercarriage for folding sled additional and has in snowfield environment
Fly, land, slide race, ground moving and the ability parked；When non-snowfield environment carry out landing when, sled can be rotated to rise
Frame ontology two sides are fallen, and ski device is easily attached with undercarriage ontology, structure is simple, easy to disassemble and maintenance.

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
It is a kind of to install the Fixed Wing AirVehicle undercarriage for folding sled, including undercarriage ontology (9), tire (7), sled dress additional
It sets, rotating device, tire (7) is located at undercarriage ontology (9) bottom, is carried out between tire (7) and undercarriage ontology (9) by axis
Connection, ski device are symmetrically distributed in undercarriage ontology (9) two sides, and rotating dress is equipped between ski device, undercarriage ontology (9)
It sets；
The ski device includes sled (8), rotary support (3), and rotary support (3) is set to sled (8) indent side, institute
Rotary support (3) are stated for carrying out rotary folding to sled (8), keep sled (8) rotation described to undercarriage ontology (9) two sides
Rotating device includes main rotating shaft (5), secondary rotary shaft (2), and secondary rotary shaft (2) connects with vertical member (1) one end axis, vertical member
(1) other end is fixedly mounted in rotary support (3), and main rotating shaft (5) connects with rod piece (6) one end axis, and rod piece (6) other end is solid
Surely it is connected on undercarriage ontology (9), connects between the main rotating shaft (5), secondary rotary shaft (2) by the way that hydraulic rod piece (4) are fixed
It connects, the rotating device is used to rotate sled (8) to undercarriage ontology (9) bottom, and rotary support (3) and rotating device are mutual
Cooperation can be realized the enabling and disabling of sled (8).
The utility model has conventional runway landing ability and snowfield landing ability, in conventional runway landing, two pieces
Symmetrical sled (8) is received in undercarriage two sides, and all tire (7) contacts to earth.In snowfield landing, main rotating shaft (5) relative to
Rod piece (6) rotation, so that hydraulic rod piece (4) be driven to rotate, secondary rotary shaft (2) is under the action of internal transmission mechanism with main rotation
The identical angular speed rotation of axis (5), to drive vertical member (1) to rotate to direction identical with hydraulic rod piece (4), when hydraulic
Rod piece (4) stops operating when rotating 180 degree, and rotary support (3) rotation stops, at this moment two sleds (8) are all arrived after being rotated by 90 °
