Abstract
The invention relates to a cabin door opening drive mechanism for a torsion bar type airliner. A driven bar is arranged on the upper end face of a suspension arm and rotationally connected with a connecting bar. The connecting bar is rotationally connected with a crank. The other end of the crank is connected with a torsion bar in a penetrating manner. A long sleeve is arranged on one side of the torsion bar. Torsion bar supporting seats are arranged at the two ends of the long sleeve respectively. The torsion bar is connected with the long sleeve through one torsion bar supporting seat. The other torsion bar supporting seat is arranged at the other end of the torsion bar and one side of the torsion bar supporting seat is connected with the crank. A short sleeve is arranged on the other side of the crank and the other torsion bar supporting seat is arranged on the other side of the short sleeve. A thin sleeve is rotationally connected to the crank and perpendicular to the torsion bar. A screw is fixedly connected to the lower portion of the thin sleeve. A support is fixedly connected to the lower end face of the screw. A pure bar-system mechanism is adopted and a four-bar mechanism is driven through the torsion bar to drive a cabin door, so that the mechanism is simple, operation is easy, reliability is high, and installation and adjustment are convenient.
Description
Technical field
The present invention relates to a kind of driving mechanism, particularly a kind of torsion-beam-type passenger plane hatch door opens driving mechanism, belongs to mechanical transmission fields.
Background technology
Current European air worthiness regulation to look for novelty development type can not adopt disposable hatch door again, the hatch door opened must be connected in fuselage, and operation will contact, this just requires that upwards overturning opening type hatch door must have assisting in opening measure, upwards overturning the escape door opened at present adopts air spring to drive, but the air spring life-span is short, and maintenance cost is high, and weight is large.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of torsion-beam-type passenger plane hatch door and opens driving mechanism, adopts pure linkage mechanism, and drive four-bar mechanism to drive hatch door by torque arm, not only mechanism is simple, and simple to operate, and reliability is high, and Installation and Debugging are convenient.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of torsion-beam-type passenger plane hatch door opens driving mechanism, suspension arm upper surface is provided with follower lever, follower lever is rotatably connected to connecting rod, connecting rod is rotatably connected to crank, the crank other end runs through and is connected with torque arm, torque arm side is provided with long sleeve, long sleeve two ends are equipped with torque arm supporting seat, torque arm is connected with long sleeve by torque arm supporting seat, the other end of torque arm is provided with torque arm supporting seat, the side of torque arm supporting seat is connected with crank, crank opposite side is provided with short sleeve, the opposite side of short sleeve is provided with torque arm supporting seat, crank is rotatably connected to thin sleeve, thin sleeve is vertical with torque arm, screw rod is fixedly connected with below thin sleeve, screw rod lower surface is fixedly connected with bearing.
Torsion-beam-type passenger plane hatch door opens an application for driving mechanism, and step is as follows:
1) be connected to inside hatch door by driving mechanism, the left and right sides of suspension arm is connected with the dual-side of hatch door, and follower lever and hatch door are opened rotating shaft and be fixedly connected with;
2) torque arm after step 1) has predetermined corner, rotary torsion bar, and power is passed to the crank be connected with connecting rod by torque arm, and power is passed to follower lever by connecting rod by crank, and follower lever rotates, and meanwhile, follower lever drives suspension arm upwards to rotate opened door.
Described sleeve rigidity is greater than torque arm.
The beneficial effect that the present invention brings is: power rod-type passenger plane hatch door opens driving mechanism without the need to extra power source, using torque arm as actuator, without the need to hydraulic pressure, air pressure or driven by power, more economically, energy saving standard, and participate in design without the need to system specialty, install, debug and safeguard, reducing design cost.
Adopt pure linkage mechanism, part is simple, and lightweight, reliability is high, and has wide range of applications.
