Definitions
- the present invention relates to a linear actuator as stated in the preamble of claim 1.
- actuators without a tube- shaped positioning element are also known, but where the spindle nut is embodied as a positioning element and at which the actuator is fastened in the construction, wherein this is built in.
- An example of such an actuator is known from WO 96/12123 Dietmar Koch. These types of actuators are typically used in armchairs or recliners.
- a motor drive was developed at the end of the 1980s, where a linear actuator was built into each end of a mutual housing. The motor drive is mounted on the pivot shafts for the back rest section and leg rest section of the bed.
- the purpose of the invention is to provide another solution for a controlled lowering or retraction of the tube-shaped positioning element, when it is released from the motor and transmission.
- Fig. 12 shows an alternative embodiment of an planetary gear
- the brake blocks 43,44,45,46 will be carried along by the rotor and will as the rotational speed increases be displaced in a radially outwards direction as a result of the influence of the centrifugal force.
- the outer side of the brake blocks 43,44,45,46 strikes the inner side of the house 39, friction develops in the contact surface, whereby the rotor 42 and accordingly the rotation of the spindle
