Embodiment Construction
[0024] refer to Figure 1-Figure 6 .
[0025] Taking a ten-gear truck as an example to illustrate this numerically controlled transmission operating mechanism, it mainly includes an electronic control command signal unit 10, a command execution unit 20, and a command execution terminal; the electronic control command signal unit includes a gear control handle 10-1 and the gear selector switch 10-2 and the shift switch 10-3 on the corresponding gear positions; the instruction execution unit 20 includes 8 groups of electromagnetic valves, the power required by the electromagnetic valves comes from the battery and the generator of the automobile, and the electromagnetic valves The required compressed air comes from the car's compressor (which shares the air source with the brake system), and the command execution terminal includes a shift multi-position cylinder 30 and a gear selection multi-position cylinder 40, and the shift multi-position cylinder 30 is perpendicular to the ge...

The invention provides a control mechanism of a numerically-controlled transmission. The control mechanism is characterized by comprising an electronic control command signal unit, wherein the electronic control command signal unit consists of a gear control handle, a gear selecting switch and a gear shifting switch on corresponding gears, the gear selecting switch and the gear shifting switch are connected with a command execution unit which is respectively connected with a gear shifting multi-position cylinder and a gear selecting multi-position cylinder, the gear shifting multi-position cylinder and the gear selecting multi-position cylinder are perpendicularly distributed, piston rods of the gear shifting multi-position cylinder and the gear selecting multi-position cylinder are connected with a gear shifting arm of the transmission through a connector, and rod-side end covers of the gear shifting multi-position cylinder and the gear selecting multi-position cylinder are respectively hinged to a frame. Compared with the prior art, the control mechanism of the numerically-controlled transmission replaces the control lever of the original automobile transmission, is strong in universality and capable of realizing modularized and integrated production so as not to consider the design of the control mechanism of the transmission when the automobile is upgraded, and the control mechanism of the numerically-controlled transmission is simple and convenient to install and debug; after a gear is engaged, the pressure applied by the gear shifting multi-position cylinder and the gear selecting multi-position cylinder continuously exists so as not to have the gear disengagement phenomenon.
Description
technical field [0001] The invention relates to the technical field of gear shifting of an automobile transmission, in particular to a gear shifting device for an automobile based on a forced-operated transmission. Background technique [0002] At present, the transmission control mechanisms of domestic heavy trucks generally adopt three types of control lever structures: single lever type, flexible shaft pull wire type and multi-rod type through the force-changing bracket conversion type. There are still some staged problems in the process of use: in order to ensure the durability of each part when the new car leaves the factory, the fit tolerance is as small as possible, which makes the new car generally heavy when it is in gear. Problems have also begun to be exposed, especially when the gear is out of gear when the road condition is poor or there is a sudden vibration. The locking force of the gear, the gear will be taken off naturally. After the gear is shifted when t...
