Abstract
The utility model provides a shock absorption system for a wheel-type dynamic parachute. The shock absorption system comprises a wheel shaft connecting rod, wherein the middle of the wheel shaft connecting rod is movably connected with a framework supporting rod through a pin shaft, the wheel shaft connecting rod is provided with a limiting groove, the framework supporting rod is also provided with a limiting groove corresponding to the wheel shaft connecting rod, and a shock absorber is wound in the limiting grooves of the wheel shaft connecting rod and the framework supporting rod. By utilizing the elastic force of a rubber band, the relative movement of the wheel shaft connecting rod and a framework system is limited; and by adjusting the winding turns of the rubber band, the softness of the shock absorption system can be rapidly adjusted, and the shock absorption system is applicable to different passengers of different weights.
Description
Technical field
The utility model relates to a kind of bumper, is used for the wheel driving force umbrella.
Background technology
The airmanship of propeller-parachuting is easy to learn, and over-the-road expense is cheap, and is safe and reliable, also is safest a kind of in all aerocrafts.The wheel driving force umbrella is that driving engine etc. is installed on the dolly of a three-wheel or four-wheel, reduce the burden that the aviator bears, dolly is at ground taxi one segment distance when taking off, and dolly lands during landing, cushion by the shock absorber on the dolly, reduce when landing impact the people.
Wheel driving force umbrella shock mitigation system in the market all is a spring shock absorption, has problems such as complex structure, Heavy Weight, cost height, size are big, dismounting difficulty, and can't regulate the soft or hard of shock mitigation system, can not well adapt to passenger's body weight.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provide a kind of simple in structure, in light weight, with low cost, size is little, be convenient to the dismounting, the wheel driving force umbrella shock mitigation system that is easy to regulate, it reduces the landing impact of wheel driving force umbrella by the elastic deformation of bungee.
The technical scheme that its technical matters that solves the utility model adopts is: comprise the wheel shaft connecting rod, wheel shaft connecting rod middle part flexibly connects through a bearing pin with strut framework, the wheel shaft connecting rod is provided with position-limited trough, strut framework and wheel shaft connecting rod corresponding position also are provided with position-limited trough, and bumper is wrapped in the position-limited trough of wheel shaft connecting rod and strut framework.The material of bumper described in the utility model is an elastomeric material.
The material of bumper described in the utility model is a bungee.
One bumper respectively is installed about strut framework described in the utility model.
The utility model bumper utilizes the elastic force of bungee, the relative motion of restriction wheel shaft connecting rod and framework, and by regulating the winding number of turns of bungee, soft or hard that can the quick adjustment shock mitigation system adapts to the occupant of different weight.
The beneficial effects of the utility model are, can improve the comfort level of wheel driving force parafoil, can play buffer action in the process of jolting by a small margin when landing; By increasing or reduce the winding number of turns of bumper, come the soft or hard of quick adjustment shock mitigation system, can make shock mitigation system adapt to heavier or light load.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a running condition scheme drawing of the present utility model.
Fig. 2 is a structural representation of the present utility model.
1. parafoils among the figure, 2. strut framework, 3. wheel, 4. wheel shaft connecting rod, 5. bumper.
The specific embodiment
Among Fig. 1, parafoil 1 is installed on the frame system, there is strut framework 2 rear end, frame system below, wheel shaft connecting rod 4 passes through a bolted connection with strut framework 2, wheel shaft connecting rod 4 and strut framework 2 can do relative motion around bolt, on the wheel shaft connecting rod 4 position-limited trough is arranged, strut framework 2 and the also corresponding position-limited trough that is provided with in wheel shaft connecting rod 4 equitant positions, bumper 5 is wrapped in the position-limited trough of wheel shaft connecting rod 4 and strut framework 2, when the wheel driving force umbrella landed impact, wheel shaft connecting rod 4 had relative open trend with strut framework 2, utilizes the elastic force of bumper 5, restriction wheel shaft connecting rod 4 opens with the relative of strut framework 2, plays the effect of damping.The one end dress inflated wheel for vehicle 3 of wheel shaft connecting rod 4.The frame system lower front end is connected with the wheel shaft front rod, and wheel shaft front rod and front vehicle wheel axis are by bolted connection, no relative motion, axle mounting wheel in the front vehicle wheel.
Among Fig. 2, wheel shaft connecting rod 4 one ends are used for being connected with wheel 3, wheel shaft connecting rod 4 middle parts and strut framework 2 flexibly connect through a bearing pin, wheel shaft connecting rod 4 is provided with position-limited trough, strut framework 2 and the also corresponding position-limited trough that is provided with in wheel shaft connecting rod 4 equitant positions, bumper 5 is wrapped in the position-limited trough of wheel shaft connecting rod 4 and strut framework 2.
Claims (4)
1. wheel driving force umbrella shock mitigation system, it is characterized in that: comprise the wheel shaft connecting rod, wheel shaft connecting rod middle part flexibly connects through a bearing pin with strut framework, the wheel shaft connecting rod is provided with position-limited trough, strut framework and wheel shaft connecting rod corresponding position also are provided with position-limited trough, and bumper is wrapped in the position-limited trough of wheel shaft connecting rod and strut framework.
