Digital Hydraulic Paver kzbin.info/www/bejne/m6TFpJeilLGKi6s The spreading speed and steering of the paver are controlled by the digital hydraulic motor which drives the two tracks. Because the digital hydraulic motor can accurately control their rotational speed and rotation angle, the paver can automatically turn and run at different speeds according to the predetermined trajectory, and realize the intelligent (unmanned) paving operation. ▉ Double track running error:< 0.1% ▉ Minimum stable running speed: better than 0.2 m / s ▉ Running repeat positioning accuracy: better than 5 mm The pitch angle of the ironing plate of the paver is adjusted by digital hydraulic cylinder (DHC). According to the comprehensive situation, ECU can change the pitch angle of ironing plate by controlling the precise displacement of digital cylinder, and finally accurately control the thickness and evenness of paving asphalt. ▉ Pitch angle DHC resolution accuracy: 0.5mm ▉ Pitch angle DHC running speed range: 0.5 - 20 mm / s arbitrary adjustment 摊铺机整机摊铺速度及转向由驱动两条履带工作的数字液压马达控制实现。由于数字液压马达可精确控制各自的转速和转角,使得摊铺机可按预定轨迹实现自动转向和不同速度走行实现智能(无人)化摊铺作业。 ▉ 双履带行进误差:< 0.1% ▉ 最低稳定行进速度:优于0.2米/秒 ▉ 行进重复定位精度:优于5毫米 摊铺机熨平板俯仰角调节则采用数字液压缸实现。ECU根据综合情况,通过控制数字缸精确位移从而改变熨平板俯仰角度,最终精确控制摊铺道路沥青厚度和平整度。 ▉ 俯仰角数字缸分辨精度:0.5毫米 ▉ 俯仰角数字缸运行速度范围:0.5~20毫米/秒任意调节
