The invention relates to the technical field of road construction machinery, in particular to a clutch control device, a method and road machinery. The clutch control device comprises a walking controller, a shift operator which is connected with walking controller signals, a clutch proportional valve and a gearbox electric hydraulic control valve group, wherein the shift operator is used for outputting shift signals to the walking controller, the walking controller is used for receiving and identifying the shift signals, sending preset clutch signals to the clutch proportional valve and sending preset gearbox shift signals to the gearbox according to the shift signals, the clutch proportional valve is used for receiving the clutch signals sent by the walking controller and controlling a clutch oil cylinder to act, and the gearbox electric hydraulic control valve group is used for receiving the gearbox shift signals sent by the walking controller and controlling the gears of the gearbox to change actions. The clutch control device, the method and the engineering machinery have the advantages that changing shift can be achieved without a mechanical transmission mode of stepping on a clutch pedal, impact is small in the process of shifting, automation degree is high, control is simple, and a manipulation effect is good.
Description
technical field [0001] The invention relates to the technical field of road construction machinery, in particular to a clutch control device, method and construction machinery. Background technique [0002] At present, the gear shifting methods adopted by the existing construction machinery are all manual gear shifting, that is, the process of "stepping on the clutch - engaging the gear - releasing the clutch". In this way, after the gear shift is completed, the speed and strength of the pedal clutch stepping and lifting are usually controlled by the operator autonomously, so as to slow down the impact and meet the speed requirements under various working conditions. [0003] Taking the road roller as an example, the road roller needs to move forward and backward frequently, and the speed should not change greatly. At the same time, in order not to affect other systems such as vibration, the engine speed is generally at the rated speed. Shifting operations are largely depe...
