Abstract
A twin-turbine torque converter belongs to the technical field of twin-turbine torque converters in the engineering machinery. The twin-turbine torque converter comprises an adjustable control valve and a torque converter housing which are arranged in a matching manner, and is characterized in that an original pressure limiting position of the torque converter housing is screwed and matched with a valve body on the adjustable control valve; and a connector of the valve body is communicated with a working oil pipe inside the torque converter housing. The twin-turbine torque converter has the advantages that the pressure limiting adjustable control valve is in the form of module type improved by original hybrid type, the structure is simple, the standardized production and the modular assembly can be implemented, and the difficulty of inconvenient debugging and maintenance during production is overcome to a great extent; in addition, the stability is enhanced due to stable working pressure.
Description
Technical field
The utility model belongs to the technical field of the twin-turbine torque converter in the engineering machinery, is specifically related to a kind of twin-turbine torque converter.
Background technique
At present, twin-turbine torque converter (specifications and models are YJSW315-6) is 4 tons (ZL40) or (ZL50) the major impetus transmission part on the loader, by housing, and movement, gear, inlet/outlet pressure controlled valve, compositions such as bearing.Fluid torque converter is the critical piece of transmission engine power, and its through-put power size is subjected to the influence of inlet/outlet oil pressure.Too high, low excessively oil pressure all can influence the proper functioning of torque-converters, therefore requires its inlet/outlet oil pressure to be controlled in the optimum range.And intrinsic import and export level pressure control valve, wherein a part is on the torque-converters housing, the size of its pressure is subjected to the housing accuracy of manufacturing, the influence of spring modulus change.The inlet/outlet oil pressure changes within the specific limits, because the influence of housing accuracy of manufacturing, the leakage of inlet/outlet valve is uncontrollable, and former inlet/outlet valve must be adjusted then by the installation test.Like this during debugging charge, effort, and adjustment accuracy is also low is given and is produced and maintenance brings difficulty.
The model utility content
At the above-mentioned problems in the prior art, the utility model purpose is to provide a kind of twin-turbine torque converter.
Described a kind of twin-turbine torque converter, comprise the adjustable control valve and the torque-converters housing that cooperatively interact and be provided with, it is characterized in that the former pressure qualification position of torque-converters housing and the valve body threaded on the adjustable control valve, the valve body connection mouth is connected with the working tubing of torque-converters enclosure interior.
Described a kind of twin-turbine torque converter is characterized in that valve inner on the adjustable control valve is slidingly matched spool is set, and the spool top is that the valve body oral area connects valve gap is set.
Described a kind of twin-turbine torque converter is characterized in that the valve core inside connection is provided with spring, and the valve gap connection is provided with the adjustment screw, and described adjustment screw cooperates with the spring socket.
Described a kind of twin-turbine torque converter is characterized in that locking nut and the fixedly connected adjustment screw of compression spring that the valve gap top is equipped with.
Described a kind of twin-turbine torque converter is characterized in that being equipped with oil drainage hole on spool, the valve gap.
Above-mentioned a kind of twin-turbine torque converter limits adjustable control valve with the former hybrid modular type pressure that is improved to, and is simple in structure, can carry out standardized production, and the modularization assembling has overcome the debugging in the production process and the difficulty of inconvenient maintenance to a great extent; In addition, stable working pressure strengthens stability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
A kind of twin-turbine torque converter, comprise the adjustable control valve and the torque-converters housing 1 that cooperatively interact and be provided with, the former pressure qualification position of torque-converters housing 1 is threaded with the valve body 4 on the adjustable control valve and cooperates, installation, dismounting, debugging, easy to maintenance, these valve body 4 slides within are equipped with spool 5, spool 5 tops are that the connection of valve body 4 oral areas is provided with valve gap 7, and spool 5 is equipped with oil drainage hole with the relevant position of valve gap 7.5 inner connections of spool are provided with spring 6, valve gap 7 connects to be provided with adjusts screw 8, described adjustment screw 8 cooperates with spring 6 sockets, locking nut 10 that valve gap 7 tops are equipped with and compression spring 9 fixedly connected adjustment screws 8, valve body connection mouth 3 is connected with the working tubing 2 of torque-converters housing 1 inside.
During work, pressure oil enters the active chamber of adjustable control valve by working tubing 2, in the anxious spool 5, when system pressure is higher than qualification pressure, pressure oil overcomes spring 6 elastic force and opens spool 5, and pressure oil can enter torque-converters housing 1 by spool oil drainage hole and valve gap oil drainage hole, makes the system pressure all-the-time stable in the scope that limits pressure, be that system's import oil pressure can stably be adjusted between 0.3～0.85Mpa, the outlet oil pressure can stably be adjusted between 0.05～0.35Mpa.Stable working pressure has guaranteed that twin-turbine torque converter transmits the stability of power.
