Shift operating device, control device, electronically controlled shift system and control method

Abstract

The invention discloses a shifting operation device, a control device, an electronic shifting system and a control method, and relates to the technical field of cranes. The shifting operation device comprises a shifting handle, a gear selecting signal sensor and a shifting signal sensor, wherein the shifting handle is connected with a gear shifting transmission shaft and a shifting transmission shaft; the gear selecting signal sensor is arranged on the gear selecting transmission shaft and used for obtaining gear selecting position information of the shifting handle and sending gear selecting signals corresponding to the gear selecting position information so that a gear selecting execution mechanism can execute gear selecting operation; the shifting signal sensor is disposed on the shifting transmission shaft and used for obtaining shifting position information of the shifting handle and sending shifting signals corresponding to the shifting position information so that a shifting execution mechanism can execute shifting operation. The gear shifting signal sensor and the shifting signal sensor are arranged and position information of the handle is read in real time, so optimal design of shifting performance can be achieved on the premise that a traditional manual shifting operation mode is not changed, and shifting comfort is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a shifting operation device, a control device, an electronically controlled shifting system and a control method. Background technique [0002] Truck cranes generally have two shifting operation modes: automatic shifting and manual shifting. The manual shifting method is to transmit force through a simple mechanical method, and the shifting force and shifting distance can be changed by adjusting the transmission ratio of the shifting mechanism, such as figure 1 As shown, the manipulator 110 converts the forward and backward motion of the gear shift handle 120 into the push and pull motion of the flexible shaft 130 , so as to shift the gear of the gearbox 140 . The transmission ratio of the shift mechanism can be adjusted by adjusting the length L2 of the shift rocker arm 150 or the length L1 of the handle rod. However, when the shift torque of the gearbox is constant, the shift f...

Problems solved by technology

However, in the prior art, the gear information unit of the shift manipulator adopts Hall sensors, the position of the shift handle can only be judged by logic, and the continuous output of the handle position information cannot be realized, the action response speed is slow, the program logic is complicated, and the reliability is low.
