The invention discloses a novel friction plate group for a hydro-viscous speed-adjusting clutch. The friction plate group comprises an input shaft (1), output shafts (2), friction plates (3), mating plates (4) and clutch pushing oil cylinder pistons (5), wherein the friction plates are provided with rigid planes and connected with the output shafts through external splines; the mating plates are connected with the input shaft through internal splines; gaps between the friction plates and the mating plates are adjusted by the clutch pushing oil cylinder pistons; and an annular surface between the internal diameter center and the high position of a spline tooth, which is 2 to 3 times the internal diameter of each mating plate, outwards is a rigid plane, and an annular surface between the high position of the spline tooth, which is 2 to 3 times the external diameter of each mating plate, and the external diameter center is a curved surface. The mating plates have curved surface structures, so that the phenomenon that the friction plates and the mating plates are completely connected or separated in the hydro-viscous speed-adjusting process is avoided; and the pressure of a pushing oil cylinder is adjusted by the friction plate group, so that the gaps between the friction plates and the mating plates can be easily adjusted in the range of 0 to 0.02mm arbitrarily.
Description
Technical field
The present invention relates to a kind of hydro-viscous speed governing clutch and use the friction plate group, specifically is that a kind of novel hydro-viscous speed governing clutch is used the friction plate group.
Background technique
The liquid viscosity transmission is a kind of novel fluid drive technology.Its utilizes the oil-shear be present between the main driven friction to be used for transferring power, can under the situation of skidding, work for a long time, carry out stepless speed regulation, and can realize the Synchronous Transmission between the main driven axle.The sticking transmission device friction plate group of existing liquid also is similar to wet clutch friction plate group, and friction plate and antithesis sheet all adopt rigid plane.Effective oil slick thickness of the sticking transmission of liquid is that the gap between friction plate and antithesis sheet is 0-0.2mm; In the course of the work; Oil slick thickness need constantly change between 0-0.2mm; And the adjusting passing ratio relief valve of oil slick thickness is regulated the pressure that the friction plate group advances oil cylinder, thereby realize in the gap that changes between friction plate and antithesis sheet.Needed adjusting pressure was generally below 0.5MPa when oil slick thickness changed between 0-0.2mm, and required the linearity of proportional pressure control valve better, otherwise was difficult to regulate.And existing proportional pressure control valve below 0.5MPa otherwise pressure non-adjustable, or the linearity is very poor.Therefore in practical application, the adjusting of oil slick thickness can't be accomplished, and friction plate is with the antithesis sheet or engages fully, or throws off the very difficult realization of liquid_viscosity regulator fully.
Summary of the invention
Problem to above-mentioned existing technology existence; The present invention provides a kind of oil slick thickness of can conveniently realizing between 0-0.2mm, to regulate arbitrarily; Have advantages such as compact structure, transmission efficiency is high, running is steady again, simultaneously cost novel hydro-viscous speed governing clutch friction plate group low, easy to maintenance.
To achieve these goals; The technological scheme that the present invention adopts is: a kind of novel hydro-viscous speed governing clutch is used the friction plate group; Comprise that input shaft, output shaft, friction plate, antithesis sheet and clutch advance oil cylinder piston, described friction plate is a rigid plane, and friction plate is connected with output shaft through external splines; The antithesis sheet is connected with input shaft through internal spline; Gap between friction plate and the antithesis sheet advances oil cylinder piston to regulate through clutch, described antithesis sheet from internal diameter outwards to the ring surface between the 2-3 spline tooth eminence doubly be rigid plane, be curved surface from 2-3 spline tooth eminence to external diameter doubly.
As preferably, the antithesis sheet from internal diameter outwards to the ring surface between 2 times the spline tooth eminence be rigid plane, be curved surface from 2 times spline tooth eminence to external diameters.
As preferably, the axial section of antithesis sheet curved surface is complete sinusoidal curve, and crest (trough) highly is 0.3～0.5mm.
As preferably, antithesis sheet thickness is 3～5mm, both has been convenient to machine shaping, can satisfy the strength and stiffness requirement again.
As preferably, friction plate is copper-base friction plate or paper-base friction wafer.
The antithesis sheet adopts curved-surface structure among the present invention; Can not cause in the liquid_viscosity regulator process friction plate and antithesis sheet or engage fully; The phenomenon that perhaps breaks away from fully; And pass through the pressure adjusting that the friction plate group advances oil cylinder, be easy to realize the adjusting arbitrarily between 0-0.2mm of friction plate and antithesis sheet gap.The axial section of antithesis sheet is a sinusoidal curve; With the friction plate engaging process of the right and left in; The annular surface that crest and trough surround can store a certain amount of working oil; Stored working oil also plays cooling action to the antithesis sheet with the part that friction plate contacts too early except that playing gearing, effectively prolong the working life of friction plate group.Friction plate group compact structure of the present invention, easy to adjust, reliable performance, cost are low, have practicability widely.

Fig. 2 is an antithesis sheet structure for amplifying schematic representation among Fig. 1.
Among the figure: 1, input shaft, 2, output shaft, 3, friction plate, 4, the antithesis sheet, 5, clutch advances oil cylinder piston.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in Figure 1; The novel hydro-viscous speed governing clutch of the present invention is used the friction plate group, comprises that input shaft 1, output shaft 2, friction plate 3, antithesis sheet 4 and clutch advance oil cylinder piston 5, and described friction plate 3 is a rigid plane; Friction plate 3 is connected with output shaft 2 through external splines; Antithesis sheet 4 is connected with input shaft 1 through internal spline, and the gap between friction plate 3 and the antithesis sheet 4 advances oil cylinder piston 5 to regulate through clutch, it is characterized in that; Described antithesis sheet 4 from internal diameter outwards to the ring surface between the 2-3 spline tooth eminence doubly be rigid plane, be curved surface from 2-3 spline tooth eminence to external diameter doubly.
As preferably, antithesis sheet 4 from internal diameter outwards to the ring surface between 2 times the spline tooth eminence be rigid plane, be curved surface from 2 times spline tooth eminence to external diameters.In order to prevent spline tooth distortion, it is too short to the results showed on the antithesis sheet 4 that rigid plane partly is difficult for, and antithesis sheet 4 rigid planes are outwards to be advisable to 2 times spline tooth height from internal diameter.
As shown in Figure 2, as preferably, the axial section of antithesis sheet 4 curved surfaces is complete sinusoidal curve, and the Wave crest and wave trough height is 0.3～0.5mm.The axial section of antithesis sheet is a sinusoidal curve; With the friction plate engaging process of the right and left in; The annular surface that crest and trough surround can store a certain amount of working oil; Stored working oil also plays cooling action to the antithesis sheet with the part that friction plate contacts too early except that playing gearing, effectively prolong the working life of friction plate group.
As preferably, antithesis sheet 4 thickness are 3～5mm.
As preferably, friction plate 3 is copper-base friction plate or paper-base friction wafer.Copper-base friction plate or paper-base friction wafer are the friction plate common used material, and the present invention can select above-mentioned common used material for use, do not influence normal use.
