Abstract (en)
[origin: WO2009062881A1] A lift drive (20) serves to drive and to detain a lift car, and it essentially contains a traction wheel (22) for transmitting a driving or detaining force to the lift car, a motor (21) for driving the traction wheel (22), and a braking arrangement for detaining the traction wheel (22). A drive shaft (2) connects the traction wheel, the motor and the braking arrangement to one another. The braking arrangement contains at least two braking devices (24.1, 24.2), wherein, according to the invention, the traction wheel (22) is arranged between the braking devices (24.1, 24.2). This is advantageous, since the braking torques (MB1,2) which are transmitted by the traction wheel (22) to the braking devices (24.1, 24.2) are divided. In the case of an advantageous, symmetrical division of the braking devices (24.1, 24.2), half on either side of the traction wheel, a torque which is to be transmitted is reduced by half in the drive shaft (2). A risk of failure or risk of breakage of the drive shaft (2) is thereby significantly reduced. In addition, during a possible failure of the drive shaft (2), there continues to be a braking function, since the braking devices (24.1, 24.2) are distributed on both sides of the traction wheel (22).
