Abstract
An elevator damping unit for reducing vertical oscillations of an elevator car when at a standstill, has brake shoe retainers provided with brake shoes. The brake shoe retainers are connected to a common electric motor via a toothed gear mechanism. The toothed gear mechanism has a central driving gearwheel, which adjoins a drive shaft of the motor, and eccentric gearwheels, which are each assigned to one of the brake shoes and are in operative connection with the driving gearwheel. The brake shoes are supported resiliently on the respective brake shoe retainers in each case via two helical compression springs.
