Embodiment Construction

[0032] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Such as figure 1 Shown is a schematic structural frame diagram provided by an embodiment of the electronically controlled shuttle shift system of the present invention. The electronically controlled shuttle shift system includes: an electronically controlled shuttle shift switch 1, a vehicle speed sensor 2, a transmission controller 3 And clutch system 4, of which:

[0034] The electronically controlled shuttle switch 1 is used to generate a shift signal according to the user's shift operation and send it to the gearbox controller 3. The electronically controlled shuttle switch 1 can be divided into three gears, namely forward gear, Neutral and reverse gears can detect different gears through sensors and generate differe...

Abstract

The invention discloses an electronically-controlled shuttle type gear shifting system and method, and relates to the field of tractors. The system includes an electronically-controlled shuttle type gear shifting switch, a vehicle speed sensor and a speed changing box controller; the electronically-controlled shuttle type gear shifting switch is used for generating a gear shifting signal accordingto gear shifting operation of a user; the vehicle speed sensor is used for acquiring the vehicle speed of a vehicle and generating a vehicle speed signal; and the speed changing box controller is used for judging whether the vehicle is in neutral or not according to the gear shifting signal, if the vehicle is not in neutral, whether the vehicle speed of the vehicle is 0 or not is judged accordingto the vehicle speed signal, if the vehicle speed of the vehicle is 0, separation and reunion of a clutch system are controlled according to the gear shifting signal, and gear shifting is achieved. According to the electronically-controlled shuttle type gear shifting system and method, electronically-controlled shuttle type gear shifting of the tractor is achieved, the problem that the gear shifting precision is low due to the fact that a pull line is used for a long time during pull-type gear shifting used by the tractor at present is solved, and the advantages that the gear shifting precision is high, and the gear shifting precision cannot be decreased after long-term use are achieved.

Description

Technical field [0001] The invention relates to the field of tractors, and in particular to an electronically controlled shuttle shift system and method. Background technique [0002] At present, the shuttle shift is the main gear shifting method for the tractor's forward and backward gears, and the forward and backward gears are switched by pulling wires. However, the cable tends to slack after long-term use, which reduces the accuracy of gear shifting control, resulting in the phenomenon that the gear cannot be engaged or out of gear. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an electronically controlled shuttle shift system, an electronically controlled shuttle shift method and a tractor in view of the deficiencies of the prior art. [0004] The technical solutions of the present invention to solve the above technical problems are as follows: [0005] An electronically controlled shuttle shift system, including: an...
