[0025] The present invention will be further described below in conjunction with the drawings:

[0026] As shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, Figure 6 Shown: The electronically controlled shift mechanism for construction machinery is mainly composed of an input unit 1, an analysis unit 2, an execution unit 3, and a feedback unit 4 connected in sequence. The input unit 1 is connected to the steering column 10 of the cab to collect the automatic reset combination handle 11 to give the shift signal and send it to the analysis unit 2. A safety protection switch 6 is also provided between the input unit 1 and the analysis unit 2 to prevent vehicles Misoperation after stopping; the analysis unit 2 processes the input shift signal and provides an execution signal to the execution unit 3 according to the position signal fed back by the feedback unit 4; the execution unit 3 executes various execution instructions given by the analysis unit 2, thereby The gear shifti...

Abstract

The invention discloses an electronic gear shifting mechanism for construction machinery, essentially comprising an input unit, an analysis unit, an execution unit and a feedback unit, which are connected serially. The input unit is connected with the direction column of a cab. A gear shifting signal is sent out by the combination handle of automatic resetting collection type and then transported to the analysis unit. The analysis unit processes the inputted gear shifting signal and provides an execution signal for the execution unit according to a position signal sent back by the feedback unit. The execution unit executes the execution dictates sent out by the analysis unit; consequently the gear shifting motion can be realized. The feedback unit tracks and sends back the actual situation of the gear shafting and transports the feedback signal to the analysis unit. The gear shifting movement of the invention accords with the stated operation mode, effectively prolonging the service life of a transmission case. Based on the change of the prior transmission case, the prior power source and the air supply of the vehicle can be used directly to realize the automatic operation mode of the speed-shifting mechanism without changing the transmission case and increasing the power unit. With a good succession, the production grade can be obviously improved.

Description

Technical field: [0001] The invention relates to the engineering machinery industry, in particular to the gear shifting system of the loader series. Background technique: [0002] At present, there are two types of shifting mechanisms known to be used on loaders: mechanical operating mechanisms such as matching domestic gearboxes and electro-hydraulic shifting mechanisms such as matching German ZF automatic transmissions. Electro-hydraulic gear shifting is widely used in foreign countries, and the structure of the gearbox is complex and the cost is high. At present, the traditional mechanical manual shift mechanism (rigid linkage mechanism or flexible shift shaft structure) is widely used in China, but this type of shift mechanism has many transmission "nodes" and the operating space of the shift handle is large, so As a result, it is difficult to assemble and adjust, the transmission efficiency is low, and the shifting is "heavy". Frequent shifting during driving is easy t...
