Abstract

The invention discloses an accelerator control device. The accelerator control device comprises a vehicle controller, an accelerator motor and an engine controller, and further comprises a signal conversion module, wherein the signal conversion module is provided with the accelerator signal converter; the input end of the accelerator signal converter is connected with the accelerator motor, and the output end of the accelerator signal converter is connected to the input end of the engine controller. The device has a signal conversion function, can effectively solve the technical problem of incompatibility of an electric control engine with a signal interface of the original vehicle control system when the electric control engine replaces a mechanical pump type engine, has the advantages of rational structure, low cost, high control precision and the like, and can be widely applied to an excavator power system with the electric control engine as the main fitting. The invention also discloses an engineering plant with the accelerator control device.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an accelerator control device for engineering machinery. The invention also relates to construction machinery provided with the accelerator control device. Background technique [0002] "Low emission and low energy consumption" has become a common issue facing the world. On October 1, 2010, my country implemented the second-stage non-road country emission regulations, and began to study the relevant indicators of the third-stage non-road country emission regulations. [0003] At present, the main configuration of the power system of most construction machinery (such as excavators) is a mechanical pump engine. This kind of engine has been widely used in the second stage of non-road countries due to its simple structure, low technical content, and low maintenance and repair costs. ; but in the face of the non-road National III emission regulations in the next stage, ...
