Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, the present invention includes a gearbox 1 and a variable speed controller 2 for controlling the gearbox 1. The variable speed controller 2 has no FNR function, and the variable speed controller 2 is connected with the variable speed operating handle 3 and the FNR operating handle 5 through the FNR function expansion module 4. The FNR function expansion module 4 is provided with an I / 0 conditioning circuit, and the I / 0 conditioning circuit is used to receive the signals of the variable speed operating handle 3 and the FNR operating handle 5, and judge the driver's operation intention according to the signals of the two handles. Then, a control signal is sent to the variable speed controller 2 through the FNR function expansion module 4 .

[0034] In this embodiment, the FNR function expansion module 4 sends a control signal to the speed change controller 2 by judging the signal of the speed change operating handle 3 to drive the a...

Embodiment 2

[0039] The difference from Embodiment 1 is that the FNR function expansion module 4 can also carry out logical analysis on the signals generated by the variable speed operating handle 3 and the FNR operating handle 5, and judge whether there is an obstacle in these two handles. When there is an obstacle, the FNR The function expansion module 4 sends out an alarm signal.

[0040] In this embodiment, the obstacle analysis logic of the FNR function expansion module 4 is:

[0041] (1) The judgment logic of the FNR function expansion module 4 on the signal generated by the shifting operating handle 3: when the shifting operating handle 3 generates only one gear signal, it is determined that the shifting operating handle 3 is working normally; when the shifting operating handle 3 generates two gear signals When there are two or more gear position signals, it is determined that the shifting operating handle 3 is working abnormally; when the shifting operating handle 3 has no signal f...

Abstract

The invention discloses an FNR device for a loading machine and a method for realizing an FNR function, and aims at providing a speed-changing operation device for a loading machine. The speed-changing operation device is low in labor intensity, low in cost and simple in structure and comprises a speed changing box and a speed changing controller controlling the speed changing box, the speed changing controller has no FNR function, and is connected with a speed-changing operation handle and an FNR operation handle through an FNR function expansion module, and the FNR functional expansion module processes speed changing signals generated by the speed-changing operation handle and FNR signals generated by the FNR operation handle; when the speed-changing operation handle is not in a neutral gear position, the FNR function expansion module outputs signals of the FNR operation handle to the speed changing controller; when the speed-changing operation handle is changed from the neutral gear position to a non-neutral gear position, the FNR function expansion module outputs signals of the speed-changing operation handle to the speed changing controller. The FNR device is simple in structure, low in manufacturing cost and suitable for the loading machine.

Description

technical field [0001] The invention relates to the field of loader gearbox control, in particular to an FNR device for a loader and a method for realizing the FNR function. Background technique [0002] When driving a loader, the driver needs to operate the steering wheel with one hand, and the two control elements of the shifting operating handle, the boom, and the bucket operating handle with the other. When the driver performs shoveling operations, one hand needs to continuously operate the two control elements in turn. , bringing great operating intensity to the driver, which can easily lead to driver fatigue. [0003] The current solution is to use the functions of forward gear, neutral gear and reverse gear (hereinafter referred to as FNR) to integrate the forward and reverse functions of the variable speed operating handle into the boom and bucket operating handles, so that the driver does not need to operate the variable speed handle, thereby reducing operations. I...
