Abstract
A modular system of driving devices that each includes a rotary drive assembly and a spindle drive assembly. The modular system includes at least two rotary drive assemblies and at least two spindle drive assemblies which are formed with coupling elements which are compatible with one another. The rotary drive of the driving device is received in a housing tube which is closed at its end remote from the spindle drive by a base piece. The base piece and the housing tube are manufactured from plastics material and are connected to one another by cohesive bonding.
Claims8
A modular system of driving devices for a flap of a vehicle, each of the driving devices comprising:
- a rotary drive;
- and
- a spindle drive having a threaded spindle and a threaded nut disposed on the threaded spindle,
- wherein the rotary drive is connected to the threaded spindle or the threaded nut via a coupling unit having a first coupling element on a side of the rotary drive and a second coupling element on a side of the spindle drive,
- wherein the threaded spindle and the threaded nut are axially movable relative to one another in reaction to a rotation of the rotary drive,
- wherein each of the driving devices of the modular system comprises a rotary drive assembly and a spindle drive assembly, wherein each rotary drive assembly comprises the rotary drive and the first coupling element and each spindle drive assembly comprises the spindle drive and the second coupling element,
- wherein the modular system comprises the rotary drive assembly and at least one additional rotary drive assembly and the spindle drive assembly and at least one additional spindle drive assembly,
- wherein the first coupling element of each rotary drive assembly and a first coupling element of each additional rotary drive assembly of the modular system are identically constructed, but the rotary drive assembly and the at least one additional rotary drive assembly have different rotary drive powers,
- wherein the second coupling element of each spindle drive assembly and a second coupling element of each additional spindle drive assembly of the modular system are identically constructed, but the spindle drive assembly and the at least one additional spindle drive assembly have different stroke lengths,
- wherein the first coupling elements of the rotary drive assembly and the at least one additional rotary drive assembly and the second coupling elements of the spindle drive assembly and the at least one additional spindle drive assembly are compatible with one another, and
- wherein one of the rotary drive assembly and the at least one additional rotary drive assembly is put together with one of the spindle drive assembly and the at least one additional spindle drive assembly to form a specific type of driving device.
