专利汇可以提供Controllable aggregate-drive for internal combustion engines, especially for motor vehicle internal combustion engines专利检索,专利查询,专利分析的服务。并且A controllable aggregate-drive for internal combustion engines, especially for motor vehicle internal combustion engines, in which a transmission ratio providing a speed increase is obtained with the aid of an adjustable V-belt transmission at low rotational speeds of the engine and a transmission ratio providing a speed reduction takes place at high rotational speeds of the internal combustion engine; the adjustment thereby takes place at the drive pulley of the V-belt transmission with the aid of an adjusting piston actuated by pressure oil against a spring force whereby the pressure space receiving the adjusting piston is filled with oil having a predetermined constant basic pressure from the lubricating oil circulation of the internal combustion engine by way of a control valve while the adjusting piston is actuated above the basic pressure by the centrifugal force of the oil-filling on the inside of the pressure space.,下面是Controllable aggregate-drive for internal combustion engines, especially for motor vehicle internal combustion engines专利的具体信息内容。
