Walking system and road sweeper
The invention relates to the technical field of road sweepers, and discloses a walking system and a road sweeper, the walking system comprises: a hydraulic transmission module comprising a driving pump assembly and a hydraulic motor assembly, the driving pump assembly is connected with the hydraulic motor assembly through a hydraulic pipeline assembly to form a driving loop; and the permanent magnet synchronous motor is suitable for being powered by a battery to rotate, and the driving pump assembly is in transmission fit with the permanent magnet synchronous motor. According to the torque curve change rule of the permanent magnet synchronous motor from the rated rotating speed to the maximum rotating speed, the permanent magnet synchronous motor has the large torque at the low speed and has the small torque at the high speed; the power performance of the electric road sweeper in complex terrains and low-speed driving during climbing is improved, and the problem that an existing electric road sweeper is poor in climbing obstacle crossing capacity is effectively solved.
本发明涉及扫路机技术领域，公开了行走系统及扫路机，行走系统包括：液压传动模块，包括驱动泵组件和液压马达组件，驱动泵组件通过液压管路组件与液压马达组件连接并形成驱动回路；永磁同步电机，适于通过电池供电转动，驱动泵组件与永磁同步电机传动配合，本发明通过永磁同步电机带动驱动泵组件，液压马达组件在液压油的驱动下带动电动扫路机的行走轮转动，通过永磁同步电机从额定转速至最大转速之间的扭矩曲线变化规律，永磁同步电机处于低速时具有较大扭矩，处于高速时具有较小扭矩，在行走系统不超过电机最大扭矩的同时，提升了电动扫路机在复杂地形以及爬坡时低速行驶时的动力性能，有效解决了现有电动扫路机爬坡越障碍能力差的问题。
