Problems solved by technology

When the original manual mechanical transmission is changed to electronically controlled mechanical transmission, the CAN bus communication protocol of the engine is often unknown, so it is difficult to realize the adjustment of the engine speed by controlling the ignition or injection device

Embodiment Construction

[0014] Axial movement and rotation mechanism is sliding sleeve 18, and the left end of sliding sleeve 18 is disc body, and its outer edge cooperates with the through hole of pulley 9, and the cylindrical body of sliding sleeve 18 cooperates with the sleeve on support 13, There is a gap between the sleeve and the disc body of the sliding sleeve 18. The left middle part along the axis of the sliding sleeve 18 is an open circular hole, and its right end has a threaded hole that communicates with the opening hole and cooperates with the stepper motor 14 shafts. . Guide mechanism is guide pin 12, and guide pin 12 is fixed on the sliding sleeve 18, and its protruding end is positioned at the helical guide groove of pulley 9. The width of the spiral guide channel is 5mm, the helix angle is 5°, and the distance from the starting point to the end point of the spiral guide channel is 1 / 4 of the cylinder where the channel is located. Pulley return mechanism is torsion spring 11. The li...

Abstract

An engine throttle auto-controlled device is used for auto-shifting of speed auto-change vehicle. The device is driven by motor, during the normal running, the press disc structure installed on the throttle axes presses tightly on the truckle surface driven by accelerator clue, with the friction on the surface, the truckle drives the press disc throttle turnning simultaneously to realize the rigid control of the throttle opening limit. When shifting is needed, the motor drives the axial moving and rotating structure move to left under the limit of the guiding structure to push the press disc to move left to be separated with the truckle surface. Under the friction of the axial moving and rotating structure with the press disc structure, the throttle starts to rotate to realize the automatically control during shifting gear. After changing gear, the engine stops rotating, comes back to the rigidity control.

Description

Technical field: [0001] The invention relates to an engine throttle control device for an electronically controlled mechanical automatic transmission vehicle. Background technique: [0002] At present, the electronically controlled mechanical automatic transmission has become a research hotspot in the field of vehicle automatic control. This automatic transmission is based on the original manual mechanical transmission and dry friction clutch. The clutch pedal is canceled and a microcomputer control device is added to realize Gearshift operation, clutch separation and combination, and automatic control of the engine speed during the gearshift process make it an automatic transmission vehicle. Since the electromechanical automatic transmission still needs to cut off the power of the engine during the shifting process, just like the manual mechanical transmission, in order to ensure the stability of the vehicle during the shifting and reduce the impact of shifting, it is neces...
