Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0025] For the convenience of description, the relative positional relationship of each component, such as: the description of up, down, left, right, etc., is described according to the layout direction of the drawings in the specification, and does not limit the structure of this patent.

[0026] Such as figure 1 - Figure 5 As shown, an embodiment of the brake hose connection structure of the frame-type landing gear of the present invention includes a buffer pillar, a torsion arm 9 and a vehicle frame 8. The torsion arm 9 includes an upper section and a lower section that can be relatively bent, and the torsion arm 9 It is installed on the piston rod 10 of the buffer pillar through the first pin shaft 901 , and the bottom of the piston rod 10 is hinged to the middle part of the vehicle fr...

Abstract

The invention discloses a frame type undercarriage brake hose connecting structure. The structure comprises a buffer supporting column, a torque arm and a frame, wherein the torque arm is installed ona piston rod of the buffer supporting column through a first pin, the bottom of the piston rod is hinged to the frame, a hose A doing bending motion along with the torque arm is installed on the torque arm, a hose B doing pitching motion along with the frame is installed on the frame, a first adapter is fixedly installed at a first set point on the piston rod, a second adapter is fixedly installed at a second set point on the piston rod, a hard pipe is connected between the first adapter and the second adapter, the other end of the first adapter is rotationally connected with the hose A, andthe other end of the second adapter is rotationally connected with the hose B. According to the frame type undercarriage brake hose connecting structure, the stress state of an undercarriage brake hose is improved, and the service life of the brake hose is prolonged.

Description

technical field [0001] The invention relates to a landing gear, in particular to a brake hose connection structure of a frame type landing gear. Background technique [0002] In a certain type of landing gear system, with the increase of the life of the first turning period of the landing gear, higher requirements are put forward for the first turning life of the matching hydraulic hose components. The structure of this type of main landing gear is a four-wheel small frame type. When the landing gear hits the ground or slides on the ground, due to the pitching of the frame and the compression of the piston rod of the buffer strut, the brake hose that provides the power source for the wheel exists in the bending part. Bending problem. Limited by the space layout, the brake hose is traditionally made of rubber hose. The rubber hose has large elasticity and small bending radius, which can meet the requirements of the actual working conditions-bending and torsion comprehensive...
