Embodiment Construction

[0042] Combine below Figure 1 ~ Figure 3 The technical solution provided by the present invention is described in more detail.

[0043] Explanation of technical terms or nouns used in this embodiment.

[0044] Power coupling: When the hybrid power system is working, it needs to work with the engine to intervene to drive the vehicle. The two power chains are superimposed to complete the fusion of power and transmit it to the actuator through an output shaft.

[0045] Pump / motor: A secondary component that can be used as both a pump and a motor. When recovering energy, it works as a pump; when releasing energy, it works as a motor.

[0046] Dual output clutch: a dual power output clutch, one of which is output through the spline structure of the pressure plate pressing force driven plate, and the other power output is from the built-in spline structure of the pressure plate, and the pressure plate is rigidly connected to the engine flywheel for output.

Abstract

The invention discloses a dynamic coupling and separating device, a hybrid power system and a crane, and relates to the field of engineering machinery. The dynamic coupling and separating device is used for disconnecting transmission chains in the hybrid power system simply and conveniently. The power coupling and separating device comprises a power take-off and a clutch, wherein the power take-off is connected with a pump / motor via the clutch; the clutch can be used for connecting and disconnecting the transmission chains between the power take-off and the pump / motor. The power coupling and separating device provided by the technical scheme can conveniently disconnect the power chains between a transmission and the pump / motor by disconnecting the clutch when requiring, and the operation is very simple, convenient and reliable.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a power coupling and separation device, a hybrid power system and a crane. Background technique [0002] Truck cranes often drive on urban roads when they are not working. When driving on urban roads, the weight of the truck crane itself is relatively large, and frequent starting and stopping consume a lot of energy. When the crane brakes, the braking torque is relatively large, which is finally dissipated in the form of frictional heat, resulting in a waste of energy. In order to improve the energy utilization efficiency of cranes, hybrid technology has emerged, which can recover the braking energy of cranes when they brake and store them in the form of hydraulic energy. When the vehicle is driven, the released hydraulic energy is converted into mechanical energy that drives the vehicle forward. [0003] Cranes using oil-hydraulic hybrid technology are called hybrid cran...
