いう欠点がある。 A liquid friction device with a temperature control device, wherein a bimetallic strip is attached to the lid of the coupling as a control member, and the bimetallic strip is arranged to act on a trip pin that passes through the lid and acts on a valve lever in a replenishment chamber for the liquid coupling. Fittings are known. The valve lever opens and closes the replenishment chamber relative to the working chamber to the appropriate degree so that a corresponding amount of coupling liquid can flow into the working chamber. The transmitted rotational moment depends on this inflow amount. Since the trip pin protrudes through the lid into the supply chamber where the coupling fluid is present, it is necessary to provide a gasket on the trip pin to prevent the coupling fluid from leaking out. In known liquid friction joints, a diaphragm or an O-ring is disposed as a seal in a portion of the area where the trip pin passes through the joint wall or lid to seal the trip pin tightly. Such trip pin packings have the disadvantage that varying frictional forces act on the trip pins in the form of the so-called "stick-slip" effect, which adversely affects the adjustment characteristics.

したことにある。 The feature of this invention is that an annular elastic diaphragm is used as the packing of the trip pin, this diaphragm is fixed to the joint wall at its outer periphery, and the frictional force between the diaphragm and the trip pin is applied to the circumferential surface of the trip pin at its inner periphery. The inner peripheral edge of the diaphragm is elastically deformed over the entire range of axial movement of the trip pin, and the diaphragm and joint wall are fitted under a residual stress set to be greater than the repulsive force resulting from the elasticity resisting deformation of The reason is that it is configured so that it can be displaced together with the trip pin.

い。 By attaching under residual stress, the inner elastic edge of the packing bends, and one corner of it bends tightly around the trip pin. During assembly, the trip pin can be inserted through the hole in the diaphragm. However, during use, no slip occurs between the trip pin surface and the edge of the diaphragm hole, the inner edge of the diaphragm remains in close contact with the trip pin, and axial movement of the trip pin is absorbed by the deformation of the diaphragm. It goes without saying that the radial dimensions of the diaphragm must be set and the material chosen such that the diaphragm can absorb this axial movement under elastic deformation.
The tightening means must also be arranged so that the inner part of the diaphragm can freely reciprocate.

る。 In another embodiment, the recess is formed stepwise in the axial direction, with a first region at the front having the same diameter as the diaphragm, and a second region adjacent to the center of the joint following the first region in the axial direction. do it like this. With this configuration, the outer peripheral area of the diaphragm is
Although the diaphragm is fitted in the recessed area, sufficient space is provided in the second area to allow the diaphragm to move axially with the trip pin. The diaphragm may be hermetically fitted to the inside or outside of the joint wall, so that when it is placed on the outside, the areas of the joint wall that would be exposed when placed on the inside are also sealed and protected from contamination.

よつて決定される。 Figure 1 shows a cross section of a liquid friction joint. This liquid friction joint has a main body 1 rotatably supported with respect to a housing 2 by a bearing 5. In the main body 1,
An operating plate 3 that rotates within an operating chamber 8 configured inside the housing 2 is attached. Although not shown, a fan blade is attached to the outer periphery of the housing 2 for supplying cold air to a cooler such as a PKW motor. The replenishment chamber 13 is a tank for a coupling fluid 6, which is supplied through a through hole 1 formed in an intermediate plate 4 that divides the internal space of the housing into a working chamber 8 and a replenishment chamber 13.
1 into the working chamber 8 . The inflow of coupling fluid is determined by the position of the valve lever 10 which closes the through hole 11 to varying degrees under temperature control.

いようにシールされていなければならない。 The front side of the housing 2 is closed off by a joint wall 12 which delimits one side of the supply chamber 13, a normally removable housing lid. A bimetallic strip 9 is attached to this joint wall, which transmits displacements due to temperature changes to the trip pin 7, which acts on the valve lever 10. The trip pin 7 must be guided by the joint wall and sealed against leakage of joint fluid.

溝に嵌着する。 There is a recess 2 in the joint wall 12 from the supply chamber side 21.
0, and this recess 20 forms an axial step into the interior of the joint wall 12, so that the recess 20 is divided into a first region 20a and a second region 20b. Diameter d 4 of the recess in the first region 20a
corresponds to the diameter of the diaphragm packing 14, and since the recess 20 has a smaller diameter d3 in the second region 20b, the inner region of the diaphragm 14 is freely movable in the axial direction. Diaphragm 1
4 is inserted, a tightening ring 15 that acts on the outer peripheral edge 18 of the diaphragm to fix and seal it is fitted into the groove.

トリツプピンの移動を案内する。 The bimetal strip is in the position shown in Figure 1 (valve open -
diaphragm 14 is the second
Take the position shown by the solid line in the figure. During assembly, the trip pin 7 is passed through the diaphragm 14 from the outside, and at this time, the inner circumferential edge 17 of the diaphragm 14 bends, stretches, and deforms to tightly fit around the trip pin 7. At this time, the diaphragm 14 first assumes the dashed line position P' in the region of the trip pin. When the bimetallic strip bends due to temperature change (first
(Fig. 2), the trip pin 7 is displaced in the direction of arrow A (Fig. 2). As a result, the inner peripheral edge 17 of the diaphragm 14 moves to the solid line position. That is, the diaphragm does not slip against the trip pin,
Guide the movement of the trip pin.

ツク効果も現われない。 As is clear from FIG. 3, the corner 30 of the inner circumferential edge 17 of the annular diaphragm 14 fits closely around the trip pin 32. The radial dimensions and material of the diaphragm 14 are such that the diaphragm absorbs axial movement by elastic deformation by the stroke H of the trip pin. in this case,
The inner peripheral edge of the diaphragm collapses and assumes position 14' in the second end position of the trip pin, with the other corner 31 in close contact with the trip pin. Therefore, over the stroke H, the inner peripheral edge moves together with the periphery of the trip pin 7. The inner peripheral edge may have a rounded shape. What is important is that the residual stress holding the inner circumferential edge 17 in close contact with the trip pin generates a frictional force that is greater than the reaction force imposed by the elastic deformation. At this time, the inner peripheral edge 17 does not slip along the trip pin. There is no slip-stick effect either.

A reliable sealing effect is achieved between P′ and the solid line position. Nevertheless, during the movement of the trip pin, no frictional forces occur between the trip pin and the diaphragm 14 that would affect the adjustment characteristics. Therefore, a reliable sealing effect is obtained that does not change the adjustment characteristics even after the joint is used for a long period of time.
