Embodiment Construction

[0017] In order to facilitate the understanding of those skilled in the art, the structural principle of the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] like figure 1 and 2 As shown, the schematic diagram of the overall structure of the central flexible shaft reversing operating mechanism in the prior art. Taking a loader as an example, the reversing mechanism usually passes through the hinge center and then leads to the front frame. The flexible shaft type reversing operating mechanism includes a joystick 1, a manipulation box 2 and a hinge center, wherein the manipulation box 2 includes a rocker 3 connected with the joystick 1, a flexible shaft 4, a flexible shaft sheath 5, and a The connecting fork 6 connected to the hinge center; the direction of the flexible shaft 4 at the bottom of the cab is to the left first ( figure 1 ) to the hinge center, after the hinge center and then for...

Abstract

The invention discloses a reversing operation mechanism. The reversing operation mechanism comprises an operation rod, a longitudinal bevel gear, a transverse bevel gear, a rocking bar, a flexible shaft, a flexible shaft sheath and a connecting fork. According to the reversing operation mechanism, the front-back movement of the operation rod is converted into the left-right movement of the flexible shaft by applying the bevel gear set, and the flexible shaft penetrates a bottom plate in a more naturally and smoothly mode after being subjected to movement reversing, the flexible shaft is prevented from generating a large friction force with the flexible shaft sheath due to the fact that the bending radius is small, so that the operation is more light and more flexible.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a reversing control mechanism. Background technique [0002] Construction machinery and vehicles usually work for a long time, and operating comfort is very important. Existing construction machinery and vehicles usually use a flexible shaft type reversing control mechanism. Generally, the flexible shaft type switching control mechanism includes a joystick and a control box, wherein the control box includes a rocker connected to the joystick, a flexible shaft and a flexible shaft guard. A sleeve and a connecting fork connected to the hinge center. The front and rear joysticks drive the rocker in the control box to swing up and down, and the flexible shaft connected to the rocker moves up and down in the flexible shaft sheath under the push and pull of the rocker. It is fixed and plays the role of guidance and protection. The connecting fork connected to the front ...
