The embodiment of the invention provides a front wheel driving system and a paver. The front wheel driving system comprises a load-sensitive pump; a first front wheel hydraulic motor provided with a first high-pressure port; a second front wheel hydraulic motor provided with a second high-pressure port; and a multi-way valve provided with an inlet, a third high-pressure port and a fourth high-pressure port, wherein the inlet is connected with the load-sensitive pump, the third high-pressure port is connected with the first high-pressure port, and the fourth high-pressure port is connected with the second high-pressure port. According to the technical scheme, by arranging the multi-way valve, a free wheel valve can be omitted, large-flow switching can be conducted, and the response speed is high. Besides, the high-pressure port of the multi-way valve is connected with the high-pressure ports of the two hydraulic motors, the two hydraulic motors can be independently controlled, the speed of the front wheel is matched according to the speed of the rear wheel, and the driving capacity of the whole vehicle is improved, so that the motors are effectively prevented from slipping; and differential speed and steering of the motors can be achieved by giving different currents to the multi-way valve, so that the driving resistance and the tire wear degree are reduced.

    本发明的实施例提供了一种前轮驱动系统和摊铺机,其中前轮驱动系统包括:负载敏感泵;第一前轮液压马达,具有第一高压口;第二前轮液压马达,具有第二高压口;多路阀,具有入口、第三高压口和第四高压口,入口与负载敏感泵连接,第三高压口与第一高压口连接,第四高压口与第二高压口连接。本发明的技术方案中,通过设置多路阀,可以取消自由轮阀,能够进行大流量切换,反应速度快。另外,多路阀的高压口分别连接两个液压马达的高压口,能够对两个液压马达进行单独控制,根据后轮车速匹配前轮速度提高整车驱动能力,有效避免马达打滑,多路阀给定不同的电流可以实现马达的差速和转向,减少行驶阻力以及轮胎磨损程度。
