Problems solved by technology

When the working air source of the airbag clutch is connected, the airbag clutch is inflated and starts to work. At this time, the diesel engine is running at the rated speed, the load suddenly increases, the diesel engine emits black smoke, and the car is stewed; the airbag clutch is affected by the impact load. Partial slipping, severe heat and wear; due to the impact load of the mechanical reducer, the damage to the gears and bearings is aggravated, and the service life is shortened

Embodiment Construction

[0010] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0011] Such as figure 1 As shown, the present invention is a reverse transmission case of a fluid coupling, which includes a fluid coupling 1 , and a quick clutch mechanism is arranged between the working chamber of the fluid coupling 1 and the fuel tank 16 . The quick clutch mechanism is a quick oil discharge pipeline arranged between the working chamber of the fluid coupling 1 and the oil tank 16; the quick clutch mechanism includes an outer cover 14 fixedly connected with the driving wheel of the fluid coupling 1, and the outer cover 14 is connected with the hydraulic coupling The working chamber of 1 is connected through the oil hole 15. A fixed conduit 13 is installed in the outer cover 14. The opening direction of one end of the fixed conduit 13 is facing the oil direction of the high-speed rotating working oil in ...

Abstract

The invention relates to a liquid coupling reverse-cutting transmission case comprising a liquid coupling, wherein a fast on-off mechanism is arranged between a working cavity of the liquid coupling and an oil tank. The liquid coupling reverse-cutting transmission case has a fast on-off response function and can shorten response time to 6-10 seconds. An added speed regulation proportional regulation control valve can realize the functions, i.e. load start, overload protection, isolated torsional vibration, slow-down impact, stepless speed regulation and fast on-off response.

Description

technical field [0001] The present invention relates to a hydraulic coupling reverse vehicle transmission box, in particular to a hydraulic coupling for drilling mud pumps for petroleum drilling rigs, municipal non-excavation horizontal directional drilling rigs, geological and water conservancy drilling rigs, etc. Reverse gear box. Background technique [0002] At present, domestic and foreign oil drilling rigs, municipal non-excavation horizontal directional drilling rigs, geological and water conservancy drilling rigs, etc. are generally equipped with traditionally configured belt-driven single-unit pump sets, that is, diesel engines are driven by cross cardan shafts, mechanical gearboxes, air bag clutches, and belts. For mud pumps, the system is bulky and complex in structure, and the flow and pump pressure can only be adjusted by adjusting the throttle of the diesel engine or changing the cylinder liner. Since the cylinder liner of the drilling pump should not be repla...
