Embodiment 1

[0030] refer to Figure 1 to Figure 5 Shown, a kind of variable front axle dual-shaft supporting mechanism comprises front axle 1, front axle sleeve 5, turning head 12, rear axle 17 and rear axle sleeve 18.

[0031] The front axle sleeve 5 is hinged with the turning head 12 through the rotating shaft 11 , so that the front axle sleeve 5 can rotate relative to the turning head 12 to change the angle between the front axle 1 and the rear axle 17 . A rotation adjustment assembly is arranged between the front bushing 5 and the turning head 12, which is driven by the rotation adjustment assembly to provide power for changing the rotation angle.

[0032] Specifically, the rotation adjustment assembly includes a connecting rod 13, one end of the connecting rod 13 is hinged with the front bushing 5 through the rotating shaft 11, and the other end of the connecting rod 13 is hinged with the slider 14 through the rotating shaft 11, and the slider 14 is slidably arranged on the turning h...

Abstract

The double-rotating-shaft supporting mechanism comprises a front shaft sleeve and a turning head, the front shaft sleeve is hinged to the turning head, and a rotating adjusting assembly is arranged between the front shaft sleeve and the turning head. The invention has the beneficial effects that the angle of the turning head is variable, so that the problems that a negative angle of attack is lost when sideslip is large and a large sideslip angle cannot be met when the angle of attack is small can be reduced; both the front shaft and the rear shaft can rotate by 360 degrees, so that more accurate and diversified sideslip angles can be realized, and only 1-degree or 0.5-degree interval adjustment can be realized without an angle changing block.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel test equipment, and in particular relates to a double-rotating-shaft support mechanism for a variable front axle. Background technique [0002] Wind tunnel experiment refers to an aerodynamic experimental method that places aircraft or other object models in a wind tunnel to study gas flow and its interaction with the model to understand the aerodynamic characteristics of actual aircraft or other objects. The double-shaft support mechanism is a commonly used mechanical device in wind tunnel experiments. However, the angle of the turning head of the existing equipment is not variable, resulting in the lack of negative angle of attack when the sideslip is large, and the problem that the large sideslip angle cannot be satisfied when the angle of attack is small. Contents of the invention [0003] The purpose of the present invention is: the present invention provides a double-shaft support mech...
