The invention relates to a pavement maintenance truck low-speed running driving device which comprises a driving device body installed on a pavement maintenance tail frame, the driving device body is composed of an installation frame and hydraulic oil cylinders, and the hydraulic oil cylinders are vertically installed at the positions, close to the bottom of the frame, of the left side and the right side of the tail frame respectively. A horizontally-arranged installation frame is arranged under the two hydraulic oil cylinders, the two sides of the top of the installation frame are welded to the bottoms of piston rods in the two hydraulic oil cylinders respectively, a driving mechanism is installed at the bottom of the installation frame, and when the pavement maintenance truck runs at a high speed, the piston rods of the hydraulic oil cylinders retract to drive the installation frame to ascend; the driving mechanism is not contacted with the ground; when the pavement maintenance vehicle runs at a low speed, the vehicle is in a neutral gear, the piston rod of the hydraulic oil cylinder extends out to drive the mounting frame to descend, and the driving mechanism on the mounting frame is in contact with the ground, so that the maintenance vehicle runs at a low speed during construction. The whole structure is simple and reasonable, installation and maintenance are convenient, and operation is safe and reliable.

    本发明为一种路面养护车低速行驶驱动装置,包括安装在路面养护尾部车架上的驱动装置本体,驱动装置本体由安装架和液压油缸组成,液压油缸分别垂直安装在尾部车架上的左右两侧靠近车架的底部位置,在两根液压油缸的正下方设置有一根水平设置的安装架,安装架的顶部两侧分别与两根液压油缸内的活塞杆底部焊接,并在安装架的底部安装有驱动机构,当路面养护车高速行驶时,液压油缸的活塞杆缩回,带动安装架升起,驱动机构不与地面接触;当路面养护车低速行驶时汽车挂空挡,液压油缸的活塞杆伸出带动安装架下降,通过安装架上的驱动机构与地面接触,实现养护车施工时低速行驶的需要。本发明整体结构简单合理,安装维修方便,运行安全可靠。
