PURPOSE: A driving wheel slip preventer is provided to substitute functions of inter-rock and differential limit device and to reduce a product cost by simplifying structure. CONSTITUTION: A spring brake chamber(2) is divided two sealed spaces(8,10) by placing a partition(6) on inside of a housing(4). The sealed spaces are divided front and rear pressure chambers(18,20,22,24) by a main brake diaphragm(14) and a parking brake diaphragm(16). An elastic member(28) is arranged on a front side of the main brake diaphragm to push backward a push rod assembly(26). An adapter push rod(30) penetrating the partition and an elastic member(32) pushing backward the adapter push rod are arranged on a front side of the parking brake diaphragm. Moreover, an elastic member(36) is installed on a rear pressure chamber(24) of the parking brake diaphragm to actuate the parking brake. The parking brake is actuated by pushing the push rod assembly through the adapter push rod while air is not supplied to the front pressure chamber by pushing forward the diaphragm.
