Particularly advantageously be that rocking arm is installed on the framework and is arranged between the two ends of rocking arm at the support that the other end always is provided with the pressure medium cylinder and second roller at their end, therefore provides favourable leverage in particular.
By axle is arranged to be pivotally mounted on the framework and two rocking arms rigidly with this ways of connecting, can obtain particularly advantageous structure, can further improve with the axle ways of connecting swingably by second rocking arm.Therefore can simplified structure, because, only require an axle in order to be rotatably mounted two rocking arms independently of each other.
When being provided with swing during fixer, improved the safety of the function of commutation actuator, so that prevent that for example support or seal ring are damaged or destroy for the part of too far and therefore commutate actuator or rocking arm of rocking arm swing.
Particularly advantageous is that the support of roller and the support of rocking arm are provided with in-line, so can not produce tilting moment by the actuating force of operating control.
Description of drawings
Illustrate according to commutation actuator of the present invention according to exemplary and unrestriced Fig. 1 below, Fig. 1 illustrates such commutation actuator with 3-D view.
The specific embodiment
Commutation actuator 1 in Fig. 1 is made up of framework 12 basically, and wherein first roller 6 here is installed on the support 8 substantially fixedly.Fixed installation here means that though roller can rotate, this roller does not have other degree of freedom basically with respect to framework 12.Second roller 5 is installed in rotation on second support 7 and with respect to the 6 adjustable ground settings of first roller, can moves with respect to first roller 6 equally.Be provided with two rocking arms 2,3, they are installed on the framework swingably the moving axis 13 that rotates for this reason.On rocking arm 2,3 second roller 5 be arranged in the support 7 rotationally and on the free end of rocking arm 2,3, be respectively equipped with an operating control 4, for example here be pressure medium cylinder, be preferably hydraulic actuating cylinder.
Rocking arm 2,3 is installed on the framework 12 so that their ground separated from each other and motion independently.For this reason, in the example according to Fig. 1, for example the axle of pipe 9 is installed in rotation on the framework 12 in two bearings 10, and wherein two bearings for example here are antifriction-bearing boxs, for example coro bearng or self-aligning roller bearing.Rocking arm 3 is permanently connected with axle 9, for example by welding, as shown in fig. 1.Second rocking arm 2 is installed in rotation on the axle 9 by means of the bearing 11 that also is antifriction-bearing box here.Therefore two rocking arm 2,3 motions irrespectively fully mutually.
But what expect easily certainly is, two rocking arms 2,3 always can be swung with suitable manner on distinctive and framework bonded assembly axle or distinctive axle journal, wherein rocking arm 2,3 can be permanently connected with axle or axle journal or be installed on axle or the axle journal, perhaps is directly installed on the framework 12.Same framework 12 is provided with the axle of rigidity, installs swingably at this upper rocker arm 2,3.
Here, pressure medium cylinder 4 at one end is fixed on the rocking arm 2,3 and at the other end and always is fixed on the framework 12, so pass through the loading of pressure medium cylinder 4, second roller 5 can and can move with respect to first roller 6 around pivot center 13 swings.The support 7 of the junction of pressure medium cylinder 4, the roller 5 in rocking arm 2,3 and rocking arm 2 always are arranged on the straight line at support on the axle 9 11 or being rigidly connected between rocking arm 3 and axle 9 in this case, so the power that is applied by pressure medium cylinder 4 in rocking arm 2,3 can not produce tilting moment.But pressure medium cylinder 4 can be fixed on the outstanding lug boss of the side direction of rocking arm 2,3 equally.
