Abstract
The present invention relates to a brake force transmission device for a brake force booster with an elastic reaction element, and input member with an associated effective surface, an output member with an associated effective surface, and a first transmission ratio that is defined by a ratio of the effective surfaces being in operative engagement with the reaction element. An object of the present invention is to provide means of a simple design, if possible arranged in the form of an assembly, giving the operator of an automotive vehicle increased support when high braking forces are required. The essence of the invention is the provision of means which starting from a determined pressure prevailing in the reaction element will reduce the reaction force introduced into the input member by a defined amount. The driver is thus given additional support, requiring a proportionately reduced increase in input force for a further increase in output force. It is thus possible for the driver to better proportion the necessarily higher brake forces after the abrupt increase in the ratio of the amplification.
