Electromagnetically operated multi-disc clutch or brake

The fire looks at an electromagnetically operated multi-disk clutch or brake with disks arranged outside the area of influence of the effective magnetic flux and an _{armature, preferably on a sleeve made of non-magnetic material 9,} for example bronze, axially displaceably supported *

Such multi-plate clutches or brakes are used in the Technology is widely used because it is in its structure and in their mode of action meet the requirements of mechanical engineering. The hiring is now based on the task to free these known versions of defects and to further improve their function *

In a preliminary electromagnetically described actuated multi-plate clutch or -Tjxemse is this "in accordance with the proposal accomplished ₉ that between the mutually associated friction surfaces of the slats about an axis rotatable rolling elements, for example rollers odo like. Arranged SiM ₉ characterized in that the rotational axes of the rolling bodies with the movement direction of the rotating K _u pplungsteile each different from 90 °

borrowed angle form ₉ and that the rolling elements are rotatably and immovably guided by a cage and / or by suitable design of the healing surfaces of the lamellae.

In mechanical friction disk clutches it is already known _{9 to} arrange rolling elements held and guided in cages between the friction disks to produce the friction fit, ₉ whose axes of rotation enclose an angle different from §ö.

The present control improves * in its entirety the effect of the previously known ^ based on friction disks Couplings as detailed below *

A multi-disc clutch or brake designed in accordance with the fire enables above all a quick construction and a quick interruption of the liaison connection and thus the Dz ^ ehmo & eates, without special means are required o the air path © ρ in the previously known. Executions to be overcome during the switching process are now almost completely omitted © Allocation from? The thermal force is to a very large extent dependent on the pressure force acting on the lamellae, the axial displacement of the lamellae and the cages guiding the erosion bodies are therefore not required ζυ, τ Sraeugung or the interruption of the hot surface outside ^ but, it is only the size of the Select the contact pressure accordingly. Sa sur generation © of the interruption of the frictional engagement only an extremely small one

Social displacement of the lamellas and the cages guiding the rolling elements is required, the air gap between the anchor bracket and the magnet body can also be made small as a result of this, so the structure of the electromagnetism. There is a rapid flow of force through the armature disk, which means that the contact pressure acting on the set of shafts does not cease; As it is "with multi- disk clutches without the lamellar body arranged by the disks, depending on the steadily decreasing air gap since τοπ, instead the entire electromagnetically generated contact force comes into effect immediately. With no other type of actuation but to achieve this fast switchability, which is specific to the design according to the design.

In the case of an electromagnetically operated multi-plate clutch, the previously beltsmiites. Kind of suEten to lanterbreehen the iiraft river; Are you able to distinguish so far from each other by leather elements or the like _? that no idling torque is transmitted via a possible oil film. "If, on the other hand, there are louvers arranged between the lamellas," as suggested by the leasing company, then only the force has to be suspended? "at a contact between the Mlskörpern nnü the fins is in fact transferred without any external forces, no or only a very low Le he running torque ,, so that in this the Lüftwege Lall can be kept small, 2um comparison may be cited _s that the smallest air gap & ei . of a hitherto customary electromagnetic clutch of a certain Ejps 3 h>&.

In a clutch of the same 2jpe with a rolling element arranged offset between the discs, the air path could be reduced to 0 _s 9,? I © with aas idling torque only half that compared to; f @ n @ 2i "with the clutch with the = air path from 3 w & shows that the torque is built up directly as a function of the low pressure and the associated contact pressure ₉ because the electromagnetic force, as a result of the cooling of the air gap, "comes into effect fully and immediately"
