Definitions
- the invention relates to a blade for a friction clutch, in particular for motorcycles.
- a friction clutch for transmitting torque fins are pressed against each other with their friction surfaces, so that a sufficient torque can be transmitted by the frictional force.
- Such slats are divided into friction plates and drive plates, which are arranged alternately, wherein the friction plates are usually connected to an output shaft via the inner radius and the drive plates are usually connected to an input shaft over the outer radius.
- the contact pressure is released, and the lamellae separate from each other automatically. In some friction clutches this is not sufficient, so that due to the friction between the slats an undesirable high drag torque is applied.
- the present invention has the object, at least partially overcome the known from the prior art disadvantages.
- the object is solved by the features of the independent claims.
- Advantageous developments are the subject of the dependent claims.
- the invention relates to a lamella for a friction clutch, which comprises an annular disk with friction surfaces on both sides and at least one receptacle for at least one spring, wherein the at least one spring is adapted to space adjacent lamellae in a friction clutch by means of the at least one receptacle.
- the lamella is characterized in that the at least one spring (10, 1) is formed integrally with the lamella (1, 2).
- the lamella designated here is in particular a lamella which can be used several times in the same design in a friction clutch. It comprises an annular disc with double-sided friction surfaces, which are adapted to transmit a torque which corresponds to the friction force multiplied by the mean radius of the annular disc, wherein the friction force per Friction surface pairing of the contact force multiplied by the respective friction coefficient corresponds.
- the lamella comprises a receptacle with which a spring can be received to an adjacent lamella.
- the spring is configured to space adjacent lamellae from one another. This prevents an excessive drag torque from being applied.
- Such a spring can be shaped in particular in the manner of a solid-state spring and / or as a leaf spring.
- Such a design of the blade has the advantage that no additional components must be used during assembly and the position of the springs can be set very accurately.
- the at least one spring is henkeiförmig formed as Torsionsbiegefeder.
- Such a henkeiförmige spring is designed as a solid-state spring. It also has several advantages: It is automatically positioned exactly, it can be made in one piece (from a circuit board) and it can be made with low mass. In addition, it can serve as a centering aid for adjacent slats by forming a (coarse) positioning stop in the circumferential direction.
- the blade on a plurality of springs, which are each formed mirror-inverted to each other.
- the mirrored springs for example, each rotated by 180 ° to the radius of the blade.
- the springs may also be bent downwards or upwards with respect to the friction surface plane.
- lugs can be formed on the lamellae, which form a counterstop for the springs and moreover firmly position the lamellas (possibly with little play) to one another. Over these tabs, the springs can be biased so that the force required to separate the slats is generated.
- These tabs can be set at the same time for transmitting the torque from the blade to an inner basket of the friction clutch.
- a friction clutch for detachably connecting an input shaft with at least one output shaft, which has a pressure plate, a plurality of lamellae, at least one driver disk and a counterplate.
- a friction clutch is adapted to releasably connect a drive unit to a drive train.
- a drive unit For example, in a motorcycle, an internal combustion engine is connected to a manual transmission.
- the friction clutch is arranged to disconnect the connection between the internal combustion engine and the transmission.
- the input shaft is connected to the drive unit and the output shaft to the transmission.
- the torque passes from the input shaft to the output shaft. But it is also a reverse torque curve, for example, for towing, transferable.
- a pressure plate is provided, via which a contact pressure on the plurality of slats according to the above description and the end arranged counter-plate is transferable.
- a frictional force is generated in this lamella system, which multiplied by the average diameter of the friction surfaces of the system gives the maximum transmissible torque.
- the lamellae are structurally identical in the friction clutch, and in particular in each case rotated relative to each other in the friction clutch can be arranged.
- At least one spring of a lamella forms a centering via the corresponding receptacle of an adjacent lamella.
- a motorcycle which has a drive unit with an output shaft, a drive train and a friction clutch for releasably connecting the output shaft to the drive train.
- a motorcycle With a motorcycle is a two-wheeled, tricycle or quad or equivalent referred to, which is driven by a drive unit, such as an internal combustion engine or an electric motor.
- the powertrain In a two-wheeled vehicle, for example, the powertrain consists of a manual transmission and a chain drive or belt drive which, for example, drives the rear wheel of the two-wheeler.
- the output shaft which outputs the torque of the drive unit, is detachably connected to the drive train via the friction clutch.
- the torques which are output via the output shaft are very high, and must be transmitted via a correspondingly efficient friction clutch. This drag moments can arise that make a shift of the gearbox uncomfortable.
- FIGS. show particularly preferred embodiments, to which the invention is not limited.
- the figures and in particular the illustrated proportions are only schematic. Show it:
- FIG. 1 shows a first lamella 1 with a first annular disc 4, which has a first friction surface 6 and a second friction surface 7.
- a one-piece first spring 10 is formed and a first receptacle 8 with a first stop 12th
- FIG. 2 shows a second lamella 2 with a second annular disc 5, which likewise has a first friction surface 6 and a second friction surface 7.
- a second integrally formed spring 1 1 is shown and a second receptacle 9 with a second stop 13.
- This blade 2 has a mirror-inverted arrangement in comparison to FIG.
- a friction clutch 3 in which a first blade 1 and a second blade 2, as shown in Figures 1 and 2, with interposed counter blades 20 is disposed below a pressure plate 19 and above a counter-plate 21. These are pressed together with the plate spring 22.
- the first blade 1 and the second blade 2 are connected to an output shaft 18, which is not shown here.
- the counter-blade 20 is connected via a clutch basket 16 with the input shaft 17.
- first fins 1 and second fins 2 are used in the identical first fins 1 and second fins 2.
- first slat 1 and second slat 2 are each mutually inserted as they are shown in the detail in FIGS. 1 and 2, in which case the slats 1 and 2 on the inner circumference 14 each alternately an arrangement as in Fig. 1 and an arrangement such in FIG. 2.
- the first spring 10 is biased by the second stop 13 and the second spring 1 1 of the first stop 12.
- a motorcycle 24 is shown as a two-wheeler, which has a drive unit 25 with an output shaft 26.
- the output shaft 26 is connected via a friction clutch 3 with a drive train 27, which is shown here only by the actuated by the hand lever 23 gearbox.
