Flexible shaft connecting link mechanism for double-accelerator control

Abstract

The invention discloses a flexible shaft connecting link mechanism for double-accelerator control, which belongs to a constant or variable-rotating speed machine for use on a skid steer loader. One end of a hand accelerator of a connecting link is connected with a hand accelerator assembly, while the other end is connected with a foot treadle flexible shaft support; a foot treadle is connected with the foot treadle flexible shaft support; the foot treadle extends downward from the position of a rotating shaft; a return spring is arranged between the extended end part and the foot treadle flexible shaft support; the foot treadle flexible shaft support on the two sides of the extended section is connected with foot accelerator support fixing bolts; the extended end part is connected with a foot accelerator flexible shaft; the end part of the foot accelerator flexible shaft is provided with an engine and accelerator connecting Y-shaped connector; and the rotating shaft of the foot treadle is also connected with a hand brake pulling plate connected with the spindle of the hand accelerator flexible shaft. The flexible shaft connecting link mechanism for double-accelerator control has the advantages of: 1, working in two states, namely a constant-speed state and a variable-speed state; 2, protecting the shaft cores of the flexible shafts from bending forces and having long service life; and 3, making installation convenient and saving space.

Description

technical field [0001] The invention relates to a machine tool used in a skid steer loader under the condition of constant rotation speed or variable rotation speed, in particular to a flexible shaft linkage linkage mechanism controlled by double throttles. Background technique [0002] In construction machinery, especially skid-steer loaders, most of them use a dual-throttle control system. Usually, the foot throttle and the hand throttle are separated. The foot throttle is connected to the engine throttle through a flexible shaft; the hand throttle is also connected to the engine throttle through a flexible shaft. The engine accelerator is connected, often in the process of stepping on the foot accelerator, the shaft of the flexible shaft of the hand accelerator also moves, especially at the connection of the engine accelerator, the foot accelerator and the hand accelerator interfere with each other when working, and the shaft of the flexible shaft bends repeatedly. , espe...

Problems solved by technology

[0002] In construction machinery, especially skid steer loaders, most of them adopt dual-throttle control system, which usually adopts the way of separating foot throttle and hand throttle. The foot throttle is connected to the engine throttle through a flexible shaft; the hand throttle is also connected to the engine through a flexible shaft The engine throttle connection, often in the process of stepping on the foot accelerator, the shaft core of the hand throttle flexible shaft also moves, especially at the connection of the engine throttle, the foot throttle and the hand throttle interfere with each other when they work, and the flexible shaft shaft repeatedly bends , especially when the force is uneven, the bending is more severe; similarly, in the process of pushing the hand throttle, the shaft core of the foot throttle connected to the engine throttle is also bent repeatedly, and the flexible shaft connected to the throttle will break after a long time
