The invention discloses a two-wheel wheel core driving clutch disc integrated type self-adaptive automatic speed changing electric driving system. The system comprises a box body, a main shaft, a motor assembly, a speed reducing assembly, a frame clutch disc mechanism and a self-adaptive transmission sensing mechanism, wherein the frame clutch disc mechanism and the self-adaptive transmission sensing mechanism are mainly arranged in a rotor. Each clutch unit axially moves back and forth in the frame clutch disc mechanism in an elastic pressure-equalizing sorting mode under the combined acting force of traction force and driving resistance, and work tasks such as power transmission, non-power transmission, transmission direction change and power distribution are completed. The inner friction plates and the outer friction plates are alternately arranged, and each equidistant space is always kept in a pressure-equalizing sequence under the elastic action of the outer elastic rings and the inner elastic rings, so that when the movable pressing disc releases pressure, each transfer synchronous check ring synchronously pushes the inner friction plates at the first time, and each inner elastic ring and each outer elastic check ring synchronously generate elastic release; gaps are synchronously formed between all the outer friction plates and all the inner friction plates, and the abrasion resistance, stability and reliability of the friction clutch are improved.

The invention discloses a forklift gearbox assembly based on an electromagnetic proportional valve and a hydraulic gear shifting control system. The forklift gearbox assembly comprises a micro-reverse gear table look-up module, a micro-forward gear table look-up module, a micro-pedal angle table look-up module, a first selection switch, a second selection switch and a third selection switch. A gearbox oil pan temperature input interface is connected with the input port of the inching-backward gear table look-up module and the input port of the inching-forward gear table look-up module. The micro-motion pedal input interface is connected with the input end of the micro-motion pedal angle table look-up module, and the output end of the micro-motion pedal angle table look-up module is connected with the input port of the micro-motion-reverse gear table look-up module and the input port of the micro-motion-forward gear table look-up module; the output end of the reverse gear input interface and the output end of the inching-reverse gear table look-up module are connected with the input end of the first selection switch; the output end of the forward gear input interface and the output end of the inching-forward gear table look-up module are connected with the input end of the second selection switch; the output end of the second selection switch is connected with the input end of the first selection switch; and the output end of the first selection switch is connected with the input end of the third selection switch, the output end of the third selection switch outputs a control current value of the electromagnetic proportional valve, gear engagement, reversing and micro-motion function execution are more accurate and smooth in function, and gear shifting impact is reduced.

This utility model discloses a ten-slot U-shaped track clutch shifting mechanism suitable for inboard and outboard engines, relating to the technical field of shifting mechanisms. It includes a multi-groove ball screw, a conical copper clutch between the upper and lower driven gears, and multiple sets of steel balls filling the space between the conical copper clutch and the ball screw grooves. A shift fork is located on the right side of the conical copper clutch. This ten-slot U-shaped track clutch shifting mechanism for inboard and outboard engines, by configuring the conical copper clutch, ball nuts, steel balls, and ball screw grooves, allows the ball nuts and steel balls inside the conical copper clutch to slide on the multi-groove ball screw through the up-and-down switching of the shift fork. The conical copper clutch, in its up-and-down sliding motion, drives the upper and lower driven gears to rotate together due to friction, achieving the purpose of shifting gears. This mechanism prevents jamming and disengagement, solving the problem of jamming and disengagement that easily occur during gear shifting.
