Disc brake mechanism or disk type braker are used for applying predetermined braking moment according to sense of rotation, slow down in order to make axle 1.Disc brake mechanism comprises first brake disc 2 and at least one first rubbing surface 3 of attaching troops to a unit be connected with axle 1 in anti-relative rotation, and they effectively can connect (Wirkverbindung) via the brake operating device 4 for applying the braking moment expected.
Arrange according to the utility model, arrange at least one second brake disc 5 with at least one the second rubbing surface 6, wherein, the braking moment that can be delivered on the second friction disk 5 can be delivered on axle 1 according to sense of rotation.
In order to realize the comfortable function transmitted according to the braking moment of sense of rotation in advised disc brake mechanism, with the second brake disc 2 differently, the second brake disc 5 such as connects with axle 1 via freewheel 7.
By this way, along the sense of rotation of idle running, the braking moment of the first brake disc 2 only can be delivered on axle 1.In the Locking Device of freewheel 7, when the second brake disc 5 is connected with axle 1 in anti-relative rotation, not only the first braking braking moment of CD 2 but also the braking moment of the second brake disc 5 are all delivered on axle 1.
As seeing from accompanying drawing, two brake discs 2,5 and the brake operating device 4 with the rubbing surface 3,6 that it is attached troops to a unit are arranged or orientation roughly coaxially relative to the rotation axis 8 of axle 1, thus on being arranged into advised disc brake mechanism can being conducive to structure space and will slowing down axle 1 dynamic.
