Detailed description of the invention
In order to linear actuator realizes reducing the purpose of load, the actuator arrangement of the present invention should be used for
Non-linearly operate clutch or the double clutch such as with linear actuator, and therefore relate to as linearly
The actuator of actuator, lever actuator, hydraulic actuator etc..The background of the present invention is, linear actuation
Device is limited to Linear transmission, and utilizes lever actuator can not realize the clutch characteristics curve successively decreased.Here,
It is very important that in order to realize non-linearity drive, linear actuator set by the present invention, lever actuator,
Layout that is that the modification of hydraulic actuator etc. comprises the dislocation of linear actuator or that tilt.
Fig. 1 illustrates lever 1, and this lever is supported on case of transmission at supporting portion 1.1, wherein, and should
Supporting portion 1.1 is arranged on the power importing in lever and imports between point 1.2 and the rotation axis X of clutch.Cause
This refers to " short " lever, also referred to as fork according to the lever 1 of Fig. 1.
The rotation axis X of clutch is the operating system (the namely operation bearing of the present invention) of clutch simultaneously
Main operation direction and the direction of motion, described operating system be applied to (namely press or draw) have lever make
Power transfer device (such as arm spring) upper or do not have on the pressure tank of lever drive.
In FIG, extreme position of lever 1 indicated by the solid line and lever 1 is represented by dashed line at this
Another extreme position.
Connector piece 4 acts on power and imports on point 1.2, and wherein, described interface unit 4 is by the first section 4.1
Form with the second section 4.2, between these sections 4.1 and 4.2, be provided with bending part 5.Bending part 5 is permissible
Being configured to can the joint of linear movement or hinge.
The operating element 3.1 of operated actuator 3 acts on again on the second section 4.2, with import operation power, and this behaviour
Then pass through interface unit 4 as power and lever 1 is further transferred on clutch.
Figure 2 illustrates the present invention for operating torque transmitter (in the power train of the vehicles
Clutch) another embodiment of lever system, described lever system corresponds essentially to the enforcement according to Fig. 1
Example, the most especially include that there is hinged bending part 5(i.e. joint depicted herein or hinge) company
Connect the section 4.1 and 4.2 of device.
With Fig. 1 by contrast, " long " lever, the most such lever it are provided with in fig. 2: this lever
Supporting-point 1.1 be arranged on clutch rotation axis relative to power import point 1.2 opposed sides on.
Figure 3 illustrates another embodiment of lever system for operating torque transmitter, be wherein similar to
In Fig. 2, arrange " long " lever.It is similar to Fig. 1 and Fig. 2, two sections 4.1 and 4.2 of interface unit 4
It is arranged on again between lever 1 and operated actuator 3, to form radial type bending part 5.
Embodiment according to Fig. 3 is with the difference of the embodiment according to Fig. 1 and Fig. 2, operated actuator 3
Import point 1.2 relative to power and be arranged on inner radial, on the contrary, according in the embodiment of Fig. 1 and Fig. 2, operate
Actuator imports point 1.2 relative to power and is arranged on radially outer.This passes through to be parallel to operation system in Fig. 1 to Fig. 3
The rotation axis of system, import some Y and the imaginary parallel lines of position Z of operating system 3 and work through power
Illustrate with the dislocation between line Z and imaginary parallel lines Y.
