The invention relates to the technical field of special modification of commercial vehicles, in particular to an improved four-wheel-drive truck comprising a front wheel, a rear wheel, a chassis, an engine and a four-wheel-drive modification system; a front driving rod and a rear driving rod are arranged between the front wheel and the rear wheel, a front differential mechanism and a rear differential mechanism are arranged between the front driving rod and the rear driving rod, the front driving rod is provided with a first front driving bevel gear, and the rear driving rod is provided with a first rear driving bevel gear; the engine and the four-wheel-drive modification system are arranged on the chassis, the engine is provided with a rear-wheel-drive transmission shaft, and the rear-wheel-drive transmission shaft is connected with the rear differential mechanism. The equipment is simple in structure, small in design difficulty and low in manufacturing cost, a driver can adopt a proper driving mechanism under a proper road condition, two-wheel-drive oil saving is achieved, four-wheel-drive escaping is rapid, the situation that driving cannot be achieved under the extreme road condition is avoided, different power distribution can be adopted for front and rear wheels through the design, and different gears are adopted according to the actual situation. Therefore, different front and rear wheel power expressions can be achieved, and daily use of a driver is more convenient.
本发明涉及商用车特种改制技术领域,具体指四驱卡车改制。包括前后车轮、底盘、发动机和四驱改制系统,前后车轮之间分别设有前驱动杆和后驱动杆,前驱动杆与后驱动杆之间分别设有前差速器和后差速器,前驱动杆设有前驱锥齿轮一,后驱动杆设有后驱锥齿轮一,发动机和四驱改制系统设置在底盘上,发动机设有后驱传动轴,后驱传动轴与后差速器相互连接。此设备结构简单,设计难度小,制造成本低,能够让司机在合适的路况下采用合适的驾驶机制,两驱省油,四驱脱困迅速,避免了在极端路况下的无法行驶的情况,此设计还可以对前后轮采用不同的动力分配,根据实际情况采用不同的档位,就会有不同的前后轮动力表现,更加便于司机的日常使用。
