液压双驱压路机普遍采用一泵双马达并联的驱动方式,机器工作时由于两个驱动轮的附着情况不同,为了发挥更大的牵引能力,在驱动结构设计和电控系统设计上都需要考虑防滑转。压路机的驱动轮发生滑转的实质是轮子输出的牵引力的趋势大于地面所能给车轮提供的附着力,由于前后轴驱动条件的差异,单钢轮的防滑转在理解和设计上都较双钢轮压路机复杂。从防滑转的角度简要说明压路机在机械结构方面和驱动设计上需要注意的问题;以销量较大的18t单钢轮压路机为例,运用具体的数值和公式说明使用防滑转和未使用防滑转控制时的压路机爬坡度的差异;并介绍两种针对不同压路机而设计的电气防滑转控制系统;指出国外的电气防滑转控制系统在压路机上应用较为广泛,国内由于技术问题和成本问题,几乎没有使用,认为国内压路机生产厂家在成本允许的范围内应使用适宜的防滑转控制技术。
Hydraulic double-drive roller is generally used in parallel with a pump drive motor, the machine work due to the two drive wheels attached to different conditions, in order to play greater traction ability in the drive structure design and electronic control system design should be considered non-slip turn. Roller wheel drive roller skid is essentially the trend of the wheel output traction greater than the ground can give the wheel adhesion, due to differences in front and rear axle drive conditions, anti-skid single wheel in the understanding and design are more than double steel Turbine complex. From the perspective of anti-slip brief description of the road roller in the mechanical structure and drive design need to pay attention to the problem; 18t single drum roller sales volume as an example, the use of specific values and formulas that use anti-skid and non-slip anti-slip control And introduces two kinds of anti-skid control system designed for different rollers; points out that the foreign anti-skid control system is widely used on the roller, the domestic due to technical and cost issues, almost no use , That the domestic roller manufacturer should allow the use of appropriate anti-slip control technology within the allowable cost.
