AI Technical Summary

Problems solved by technology

With ordinary universal joints, it is impossible to limit the swing speed of the suspension shaft. With adjustable universal joints composed of rotary dampers, it is impossible to pull people back to the center in time when the human body is away from the center. People are moving forward, backward and forward. Left and right movement requires different rebound damping levels

Embodiment Construction

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 5 As shown, an elastic damping universal joint of the present invention includes a fixed fork 100 , a cross shaft 200 , a linear damper 300 and a spring 400 . like figure 1 As shown, the fixed fork 100 includes a yoke portion 101 with an arc-shaped structure and a yoke handle portion 102 for connecting external components. The two front ends of the yoke portion 101 are respectively provided with cross shaft fixing holes 104 for connecting the cross shaft 200. The four shaft ends of the corresponding cross shaft 200 respectively have a fixed fork fixing part 201 that is compatible with the cross shaft fixing hole 104; the middle part of the fork arm part 101 is provided with damper hinges on both sides near the fork handle part 102. Part 103; the fork handle part 102 is a hollow cylindrical structure, and there are threade...

Abstract

The invention discloses an elastic damping universal joint which comprises two vertically and crisscross arranged fixing forks, a universal joint pin for connecting the upper and lower fixing forks and linear dampers. Each fixing fork comprises a fork arm portion and a fork handle portion for an external connecting part, and four pin rods of the universal joint pin are connected with the fork armportions through the linear dampers. The elastic damping universal joint can provide universal swing for external connecting parts connected at two ends of the elastic damping universal joint and doesnot produce axial rotation. In addition, a certain elastic damping is provided for the swing through the arranged linear dampers, excessive speed can be inhibited, and the joint has the capability ofrestoring to an initial position.

Description

technical field [0001] The invention relates to a transmission structure part of a suspension system, in particular to an elastic damping universal joint. Background technique [0002] In some suspension systems, there are certain requirements for the movement of the suspension shaft, such as a limit on the maximum swing speed, and no axial rotation during the swing process, or special requirements for the damping characteristics of two or more different directions . If a suspended positioning belt is used for safety protection and position measurement of the human body, it is necessary to ensure that the suspended belt provides protection when the human body accidentally falls, and in order to accurately measure the position of the human body, the suspended positioning belt cannot move along the axis when the shaft swings. In addition, when the human body is away from the center, it can pull the person back to the center in time. When the person is moving forward, backward...
