Further advantageous developments of the present invention will become apparent from the dependent claims and the following description of preferred embodiments. This shows, partially schematized, the only:

1 a door brake assembly with a door brake according to an embodiment of the present invention.

1 shows a door brake assembly with a door brake according to an embodiment of the present invention for braking a door 2 of a motor vehicle.

The door brake has a (first) braking surface (top in 1 ) with several cams 5 and another braking surface (below in 1 ) with a plurality of cams on opposite sides of a door catcher 4 are arranged.

The door catcher 4 is on a door pillar of a body 1 articulated of the motor vehicle.

The door brake further comprises a (first) brake device with a housing 3 for braking a movement of the first braking surface relative to this (first) braking device (at the top of FIG 1 ) and another braking device 3. ' (below in 1 ) for braking a movement of the first braking surface relative to this (first) braking device, which on opposite sides of the door catching belt 4 arranged and designed to each other and act, so that in particular the first brake device 3 explained in more detail and to the further braking device 3. ' reference is made to this. In a modification, not shown, one of the two braking devices can also be omitted.

The brake device 3 respectively. 3. ' has in each case a displaceably mounted (first or further) brake member 6 on, between any two of the cams 5 retract and so a (increased) braking force on the respective braking surface or the door catch 4 can imprint.

The brake member 6 is in each case reversible by increasing a volume of a (first or further) hydraulic or hydraulic fluid-filled working space 13 towards the (first or further) braking surface out and under reduction of this volume away from this braking surface adjustable, wherein a braking force of this brake member 6 is reduced to the corresponding braking surface under or on reduction of this volume.

The brake device 3 respectively. 3. ' each has a (first or further) valve means in the form of a 2-way valve 11 on, a hydraulic connection between the respective working space 13 and an associated (first or further) equalization space 12 optional locks.

The first compensation room 12 leads with open first valve means 11 Hydraulic fluid automatically without a driven pump through this in the first working space 13 back. Analogously, the further expansion chamber automatically leads hydraulic fluid when the valve is opened further, without a driven pump, into the further working space. In this case, this automatic feedback takes place in the first brake device (above in 1 ) due to gravity and by a pneumatic force accumulator in the form of a compressible gas volume, in the further braking device (below in 1 ) against gravity only by a pneumatic energy storage in the form of a compressible gas pressure pad 20 ,

The 2-way valve 11 is in each case a solenoid valve, which is open in unaktuiertem or de-energized state. In a modification, not shown, it may also have one or more discrete partially open or -schlossene positions except a fully open and a fully closed position or be a continuously adjustable valve.

The first brake member 6 is resiliently biased by a spring means against the first braking surface. Analogously, the further braking member by another spring means 14 resiliently biased against the further braking surface.

An end face of the first brake member 6 forms or defines a wall of the first working space 13 , Analog forms or defines the further brake member a wall of the other working space.

The (first or further) equalization room 12 is (in each case) designed as a closed up to the hydraulic connection chamber.

A control agent 21 controls electrical the first and the further valve means 11 ,

Shall the door 2 in a position where the brake links 6 between two cams 5 engage, be braked, closes the control means 21 the valve means 11 , As a result, a discharge of hydraulic fluid from the respective work is prevented in the respective compensation space and the respective brake members 6 hydraulically fixed in its extended position.

To cancel this or in case of power failure open the valve means 11 , This allows the brake links 6 the cams 5 overrun, with a retraction movement of the brake links 6 Hydraulic fluid is discharged from the respective working in the respective compensation chamber.

Driving the brake links 6 as a result of the spring means 14 again between two cams 5 a, is reversed by the respective valve means 11 Hydraulic fluid automatically returned from the respective compensation in the respective working space, as long as the valve means 11 is opened and this is controlled accordingly or is de-energized.

It can be seen that in a valve with a plurality of discrete partially open or closed positions and a continuously adjustable valve, the braking force is variably enlarged or reduced, which in particular the door 2 slowed down slower and / or a braking force can be impressed, which can be overcome under a variably predetermined, in particular controllable, increased force.

Although exemplary embodiments have been explained in the foregoing description, it should be understood that a variety of modifications are possible. It should also be noted that the exemplary embodiments are merely examples that are not intended to limit the scope, applications and construction in any way. Rather, the expert is given by the preceding description, a guide for the implementation of at least one exemplary embodiment, with various changes, in particular with regard to the function and arrangement of the components described, can be made without departing from the scope, as it turns out according to the claims and these equivalent combinations of features.
