    • The present invention is directed to a power transmission apparatus for a power driven lawn mower. The lawn mower has a housing, an engine mounted on the housing, a moving blade coupled to the engine and wheels which are swingably mounted on the housing. The swinging of the wheels moves the housing towards and way from the ground in order to raise and lower the housing to thereby raise and lower the lawn mower blade. The power transmission apparatus comprises a transmission mechanism and a transmission chamber for housing the transmission mchanism, the chamber including a guide structure. The transmission mechanism includes a drive shaft coupled to the engine and a single reduction gear mechanism coupled to the drive shaft and the wheels for transmitting the rotation of the drive shaft to the wheels. The reduction gear mechanism includes an engaging structure for engaging the guide structure in the chamber wherein the swinging movement of the wheels causes a corresponding movement of the reduction gear mechanism. The corresponding movement of the reduction gear mechanism is guided by the movement of the engaging structure in the guide structure.
    • 本发明涉及一种动力驱动割草机的动力传递装置。 割草机具有壳体,安装在壳体上的发动机,联接到发动机的可动叶片和可摆动地安装在壳体上的轮子。 轮的摆动使壳体朝向和离开地面移动,以便升高和降低壳体,从而升高和降低割草机叶片。 动力传递装置包括传动机构和用于容纳传动机构的传动室,所述腔室包括引导结构。 传动机构包括联接到发动机的驱动轴和联接到驱动轴和车轮的单个减速齿轮机构,用于将驱动轴的旋转传递到车轮。 减速齿轮机构包括用于接合腔室中的引导结构的接合结构,其中车轮的摆动运动引起减速机构的相应运动。 减速齿轮机构的相应运动由接合结构在导向结构中的运动引导。

    • A riding type mower includes steered front wheels and driven rear wheels arranged in the front and rear parts of a vehicle body, respectively, a mowing cutter mechanism disposed under the vehicle body, a driver's seat disposed on the vehicle body, and an engine for driving the rear wheel and the mowing cutter mechanism. The driver's seat is disposed substantially at the longitudinally central part of the vehicle body, the engine is disposed below the driver seat, a fuel supply system of the engine is disposed at one side of the engine, and an exhaust system of the engine is disposed at the other side of the engine. Power of the engine is transmitted through a pulley belt to an input shaft of a transmission gearing for the rear wheels, with the transmission gearing being disposed behind a rear axle, and concurrently from the input shaft through another pulley belt to the cutter mechanism which is level-adjustably disposed substantially in the longitudinal central part of the vehicle body. The cutter mechanism housing has a maximum transverse width of dimension less than the distance within the respective transversely outside faces of the rear wheels. The cutter housing is disposed substantially in the longitudinally central part of the vehicle body, while the engine is disposed within a contour of the cutter housing as viewed from above.
    • 一种骑马式割草机包括分别设置在车身前部和后部的转向前轮和从动后轮,设置在车身下方的割草机构,设置在车体上的驾驶员座椅和用于驾驶的发动机 后轮和割草机构。 驾驶员座椅基本上设置在车体的纵向中心部分处,发动机设置在驾驶员座椅的下方,发动机的燃料供给系统设置在发动机的一侧,并且设置发动机的排气系统 在发动机的另一侧。 发动机的功率通过皮带轮传递到用于后轮的传动齿轮传动装置的输入轴,传动齿轮装置设置在后轴的后面,同时从输入轴通过另一个皮带轮到切割机构, 水平可调节地设置在车体的纵向中心部分。 切割机构壳体具有的尺寸的最大横向宽度小于后轮的相应横向外表面内的距离。 切割器壳体基本上设置在车体的纵向中心部分中,同时发动机设置在从上方观察的切割器壳体的轮廓内。
