Spring-loaded brake with pressure-medium-operable lifting set

摘要

A spring-loaded brake may be modulated by an integrated brake-actuating cylinder of almost unchanged constructional length, arranged radially above a spring-packet which acts in a direction contrary to the lifting force of the cylinder. The brake still has the automatic emergency stopping function of the parking brake principle. The spring packet acts against a brake piston which is acted upon by pressure at both ends by cylinders which are equipped with gaskets for sealing them both against each other and against the transmission housing. The brake discs and splash lubrication of the transmission are in communication via oil passage sections. The brake housing is designed as an assembly built into the transmission and its cover flange may be equipped with a shaft seal for fitting a shaft extension to a drive shaft. The brake hub body can be shaped as a shaft flange which brake hub body can also be the hub of a gear wheel.
