The invention discloses an automobile double-group power clutch four-wheel drive system which comprises a front axle drive assembly used for providing power for front wheels and a rear axle drive assembly used for providing power for rear wheels, the front axle drive assembly adopts a brake transmission system, a shifting fork transmission system or a clutch transmission system, and correspondingly, the rear axle driving assembly adopts a brake transmission system, a shifting fork transmission system or a clutch transmission system. The four-wheel driving force system based on the front axle driving assembly and the rear axle driving assembly formed by combining various power clutches enables the front axle driving assembly and the rear axle driving assembly to be respectively and flexiblyprovided with a medium-low speed driving system and a medium-high speed driving system. The front axle drive assembly and the rear axle drive assembly select the respective optimal output power through braking, shifting forks and clutches and then conduct superposition to obtain the optimal driving working condition, an automobile has the medium-low-speed driving interval and the medium-high-speed driving interval, and the comprehensive performance that the medium-low-speed section is strong in power, rapid in starting, lower in energy consumption of the medium-high-speed section and safer tocontrol is highlighted.
本发明公开了一种汽车双组动力离合四驱系统,包括用于给前轮提供动力的前桥驱动总成和用于给后轮提供动力的后桥驱动总成,前桥驱动总成采用制动传动系统、拨叉传动系统或离合传动系统,相应地,后桥驱动总成采用制动传动系统、拨叉传动系统或离合传动系统,这种基于多种动力离合组合成前桥驱动总成和后桥驱动总成的四驱动力系统,使前后桥驱动总成各自灵活配置中低速和中高速的驱动系统,前后桥驱动总成先通过制动、拨叉和离合选择各自最佳输出动力再进行叠加以获得行驶最佳工况,实现汽车兼具中低速行驶区间和中高速行驶区间,突出中低速段动力强劲、起步快速和中高速段能耗更低、安全操控的综合性能。
