A device for adjusting electronic accelerator pedal for engine bench test

Abstract

The invention discloses a device for adjusting an electronic accelerator pedal in an engine bench test, comprising a base (1), a support side plate (4), an adjustment rod (5) and an adjustment rod support plate (6): The assembly hole (10) of the electronic accelerator pedal; the supporting side plate includes a connecting portion (41) and a supporting portion (42) protruding upwards and obliquely to the right from one side of the connecting portion; the adjusting rod supporting plate includes an assembling portion (61) And the mounting part (62) protruding vertically outward from one side of the assembly part; the supporting side plate is fixedly connected with one side of the base through its connecting part in an adjustable position; the adjusting rod supporting plate is connected with the supporting side plate through its fitting part One side of the upper part of the support part can be fixedly connected in an adjustable position; the adjusting rod is rotatably connected to the mounting part of the adjusting rod support plate, and its right end surface (52) protrudes from the mounting part of the adjusting rod support plate. The invention can precisely adjust the stroke of the electronic throttle.

Description

technical field [0001] The invention belongs to an engine bench test device, in particular to a device for adjusting an electronic accelerator pedal for an engine bench test. Background technique [0002] At present, in the engine bench test, the throttle actuator servo motor on the dynamometer is used to pull the electronic accelerator pedal through the accelerator cable between the test benches or use the EGAS input voltage instead of the electronic accelerator pedal to adjust the engine load. Adjust the accelerator pedal opening. Its defect is that when the speed and load characteristics are small, the throttle adjustment servo motor used in the dynamometer bench has a large range of adjustment, and the EGAS input voltage (0-5V) of the bench to control the electronic throttle is also difficult to be accurate. Adjusting the throttle opening will lead to large changes in the throttle opening. It is difficult to adjust the ideal engine output load (such as ±1N·m), which gre...

Its defect is that when the speed and load characteristics are small, the throttle adjustment servo motor used in the dynamometer bench has a large range of adjustment, and the EGAS input voltage (0-5V) of the bench to control the electronic throttle is also difficult to be accurate. Adjust the throttle opening, resulting in large changes in the throttle opening, it is difficult to adjust the ideal engine output load (such as ± 1N m), which greatly affects the test results and test efficiency of the engine bench load characteristics
