Embodiment Construction

[0022] The present invention will be further described below by means of specific embodiments:

[0023] In the storage position, the included angle between the side roll axis and the horizontal reference line of the aircraft fuselage is relatively large, so that the refueling pipe is close to the aircraft fuselage for storage. When the refueling pipe is lowered, the actuator pushes the sleeve to rotate around the hinge point A through the rocker arm linkage mechanism, the angle between the side roll axis and the horizontal reference line of the aircraft decreases, the position of the hinge point B moves down, and the distance from the aircraft fuselage becomes farther , the refueling pipe moves up and down with the hinge point B as the axis, the side roller shaft can rotate in the sleeve, and the side roll of the refueling pipe is realized through the side rolling fork lug fixedly connected with it, and the refueling pipe is kept under the action of aerodynamic force The cross...

Abstract

The invention belongs to the field of mechanical structure design, and particularly relates to an improvement of a universal joint movement mechanism. The rolling type universal joint movement mechanism is characterized by comprising seven parts including a fixed support seat, an actuator cylinder, a rocker arm connecting rod mechanism, a side rolling shaft, a sleeve of the side rolling shaft, a side rolling fork lug and an oil filling pipe connecting support seat, and the like, wherein the sleeve of the side rolling shaft comprises a front end cover, a cylinder body and a rear end cover; the connection relationship of the components is as follows: the fixed support seat is connected with the actuator cylinder, a rocker arm and the sleeve of the side rolling shaft in a way of hinge joint; the actuator cylinder is connected with the rocker arm in a way of hinge joint; a connecting rod is connected with the sleeve of the side rolling shaft in a way of hinge joint; the side rolling shaft is arranged in the sleeve of the side rolling shaft and is supported by a bearing and a bushing; the side rolling shaft passes through the rear end cover of the sleeve of the side rolling shaft and is closely fixed with the side rolling fork lug by a bolt; and the side rolling fork lug is connected with the oil filling pipe connecting support seat in a way of hinge joint. The rolling type universal joint movement mechanism is simple in the fundamental principle, fast in installation and debugging and convenient to maintain, and is capable of meeting the use requirement of an oil filling pipe which flexibly moves in a control envelope curve of an airplane.

Description

technical field [0001] The invention belongs to the field of mechanical structure design, and in particular relates to the improvement of a universal joint movement mechanism. Background technique [0002] This invention is different from traditional universal joints, fork joints or cross joints. It needs to use the rolling characteristics of this mechanism to keep the direction of the installation shaft matching the airflow performance. This kind of rolling universal joint has never been designed in China before. To the joint movement mechanism. The applicant has not found any universal joint kinematic mechanism with similar functions and principles in the retrieved patent documents. [0003] In the European patent GB586271, a device for improving the aircraft's field of view during the dive bombing process is disclosed, which is a cam-link rocker mechanism, and its function and principle are very different from the present invention. [0004] In Chinese patent CN02823572...
