Control system for manual or automatic electric-control mechanical gearboxes

Abstract

The invention relates to a control system for manual or automatic electric-control mechanical gearboxes, which comprises a gear selection device, a gearbox push-and-pull device, a clutch control device, a throttle control device, a central control box and connecting wires. In the invention, at least two electric ball-screw push-and-pull devices are arranged on the upper cover of the gearbox, are connected with the tail end of a shifter fork and realize the movement of the shifter fork; the other electric ball-screw push-and-pull device pulls the clutch to cut off the power of the engine at the time of gear shifting; and meanwhile, the throttle control device keeps the engine speed unchanged at the time of gear shifting, thereby achieving the goal of gear shifting, solving the technical problem that the power interruption and the like in the prior mechanical automatic gearbox at the time of gear shifting affect the comfort for driving. The invention has the advantages of simple structure, high reliability, high controllable precision for push and pull force and operating rate, low price, high work efficiency, good product uniformity, and convenient maintenance and replacement.

Description

technical field [0001] The invention relates to a control system of a manual or automatic electronically controlled mechanical shift fork type gearbox Background technique [0002] At present, most of the domestic common mechanical shift fork-type gearboxes (MT gearboxes) are controlled by mechanical handles (MT system), that is, the shift lever can be moved by hand to change the meshing position of the gears in the gearbox and change the transmission ratio, so as to achieve gear shifting. the goal of. When the clutch is depressed, the shift lever can be moved. If the driver is skilled, a car equipped with a manual transmission is faster and more fuel-efficient than an automatic transmission when accelerating and overtaking. MT gearbox is the most widely used transmission at present. However, this method is labor-intensive to operate, and the installation position of the gearbox is limited. [0003] Another kind of transmission is an automatic transmission (AT transmissi...

Problems solved by technology

[0005] The purpose of the present invention is to provide a manual or automatic electronically controlled mechanical transmission control system, because the operating speed and the position of start and stop can be precisely controlled when the actuator is working, so it improves the existing mechanical automatic transmission. Technical issues such as power interruptions that affect driving comfort
