Description
Technical field
The utility model belongs to vehicle technology field, in particular to a kind of small drone wheel-retracting gear.
Background technique
Undercarriage, which is aircraft, which to be parked on ground, slides, takeoff and anding is sliding is used to support aircraft gravity when running, and bears corresponding carry
The device of lotus.
When aircraft flies at low speed, the requirement to Aerodynamic Configuration of Aireraft is not very stringent, therefore the undercarriage of this kind of aircraft is all
Be it is fixed, such manufacture difficulty is accordingly smaller, and when aircraft flight in the sky, undercarriage is still exposed to except fuselage.
With the continuous improvement of aircraft flight speed, the resistance of flight can also sharply increase therewith, at this moment, be exposed to outer
Undercarriage has just seriously affected the aeroperformance of aircraft, therefore, it is necessary to design retractable undercarriage, can be retracted into flight
Within wing or fuselage, when landing, puts down the respective loads for bearing aircraft again.
Conventional Take-off and Landing frame is acted using hydraulic-driven pressurized strut, is rotated around folding and unfolding shaft to push and pull undercarriage to realize
Draw-in and draw-off function, this structure will have a set of hydraulic drive circuit, and system complex, control difficulty is big, not be suitable for small-sized nothing
On man-machine.
Utility model content
The utility model provides a kind of novel small drone wheel-retracting gear, solves the above conventional Take-off and Landing
Frame jack in small drone with when there are the problem of.The mechanism is directly driven using steering engine by gear drive
The rotation of folding and unfolding shaft, and folding and unfolding shaft and undercarriage are connected, the rotation of folding and unfolding shaft can drive undercarriage control, this is practical new
Type greatly simplifies the structure of Landing Gear System, and this mechanism controls is easy, is reliable.
The utility model uses following technical scheme: a kind of small drone wheel-retracting gear, including steering engine, steering engine
Bracket, pinion gear, gear wheel, transmission swing arm, main support, gear drive shaft, the steering engine is on steering engine bracket, steering engine bracket
On main support, the drive shaft of pinion gear is located on steering engine, and for gear drive shaft through bearing on main support, gear wheel is solid
Mounted in gear drive shaft one end, gear wheel engages composition gear drive with pinion gear, and rotation swing arm is packed in gear driving
On axis.
Preferably, the steering engine is two, which is provided with the pinion gear of same size, is meshed respectively with gear wheel.
A kind of small drone wheel-retracting gear of the utility model, for pinion gear on steering engine, steering engine is mounted in steering engine
On bracket, for gear drive shaft on main support, pinion gear and gear wheel form gear drive.The utility model uses rudder
Machine directly drives the rotation of folding and unfolding shaft by gear drive, to control undercarriage control as driving mechanism.This is practical new
Hydraulic drive circuit in the prior art and push-pull device at fixed is omitted in type, greatly simplifies structure and control is easy, is reliable.
The wheel-retracting gear has the following advantages:
1. the utility model, as driving mechanism, is omitted a big set hydraulic drive circuit, simplifies structure using steering engine,
Control is easy, is reliable；
2. the utility model directly drives the rotation of folding and unfolding shaft using gear drive to realize undercarriage control, it is omitted and pushes away
Drawing device further simplifies structure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the small drone wheel-retracting gear of the utility model embodiment 1.
Figure label respectively indicates are as follows: (1) steering engine；(2) steering engine bracket；(3) pinion gear；(4) gear wheel；(5) transmission pendulum
Arm；(6) main support；(7) gear drive shaft.
Specific embodiment
Embodiment 1
Technical solutions of the utility model are discussed in detail with reference to the accompanying drawing.
As shown in Figure 1, the present embodiment uses Twin Rudders present embodiment discloses a kind of small drone wheel-retracting gear
Machine driving, one-stage gear are driven.Two steering engines 1 are attached separately on steering engine bracket 2, and steering engine bracket 2 is mounted on main support 6,
Pinion gear 3 is on steering engine 1, and for gear drive shaft 7 through bearing on main support 6, gear wheel 4 is packed in gear drive shaft 7
The other end, gear wheel 4 engage composition gear drive with pinion gear 3, and rotation swing arm 5 is packed in gear drive shaft 7.
1 driving pinion 3 of double steering engine of the present embodiment rotates, and is rotated by gear pair, then band moving gear drive shaft 7, and
Driving torque can be amplified by the transmission of gear, transmission swing arm 5 is connected in gear drive shaft 7, this can drive biography function
The deflection up and down of swing arm 5, to realize the folding and unfolding of undercarriage.
Embodiment 2
Present embodiment discloses a kind of small drone wheel-retracting gears, unlike the first embodiment, using single rudder
Machine driving, can meet the undercarriage of less demanding to driving torque.
The utility model small drone wheel-retracting gear can be used single steering engine or more servo drivings, can also adopt
It is driven with multi-stage gear, requirement of the undercarriage to topology layout can be met.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, although ginseng
The utility model is described in detail according to previous embodiment, it for those skilled in the art, still can be with
It modifies the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.It is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
