Definitions

  • the invention relates to a mobile floor cleaning machine, comprising a chassis, arranged on the chassis rear wheel means, a steerable front wheel means, and a handlebar means, which is coupled torque-effectively to the front wheel means.
  • Mobile floor cleaning machines are known from EP 0 934 017 B2 and US Pat. No. 7,082,639 B2.
  • the invention has for its object to provide a mobile floor cleaning machine of the type mentioned, which can be produced in a simple manner or has a low weight.
  • the front wheel is held on a support which is fixed to the chassis, and that on the support a torque transmitting device for transmitting torque from the handlebar to the front wheel means is arranged, wherein the handlebar means torque-effectively coupled to the torque transmitting device.
  • the chassis and the carrier can be optimized separately.
  • the carrier can be formed so that an optimized coupling of the front wheel and the steering rod device is achieved in particular with respect to storage and with respect to power and power take-off.
  • the chassis can then be easily manufactured and, for example, made of a plastic material.
  • a torque can be transmitted in an optimized manner from the handlebar device to the front wheel device, so that a steering movement can be directly converted to a corresponding movement of the front wheel device.
  • the coupling of the handlebar device to the front wheel device can be effected directly via the torque transmission device, or an intermediate transmission can be provided.
  • the carrier is a separate element from the chassis, which is connected to the chassis.
  • the carrier and the chassis are made separately and then connected together. As a result, these two components can be optimized separately.
  • the carrier is plate-shaped. It can be realized with low weight and easily connect to the chassis. It is favorable if the carrier is made of a metallic material and in particular of a light metal. He can thereby be produced on the one hand with relatively low weight. On the other hand, it is possible to absorb or divert great forces through it. It can easily stock how a pivot bearing for the front wheel device and a pivot bearing or a rotary guide for the handlebar device are arranged on the support or integrated into it. It is advantageous if a pivot bearing and / or a rotary guide for the handlebar device is arranged on the carrier. This allows an optimized guidance to be achieved.
  • the carrier has an upper side and a lower side facing away from the top, wherein at bottom mounted on a floor to be cleaned floor cleaning machine faces the ground, and the pivot bearing or the rotary guide is disposed on the top and in particular the torque transmitting device on the underside is arranged.
  • the invention is further based on the object to provide a floor cleaning machine of the type mentioned, which has a low susceptibility to wear.
  • a toothed belt device is provided as a torque transmission device for torque transmission from the handlebar device to the steerable front wheel.
  • a toothed belt device has a relatively large backlash and low susceptibility to wear.
  • the handlebar device is non-rotatably connected to a first pulley and the front wheel device is rotatably connected to a second pulley, and there is a toothed belt for rotary torque transmission to the first pulley and the second pulley arranged.
  • the handlebar device offset to the front wheel means with respect to corresponding axes of rotation can be arranged. It can then use the available space on the floor cleaning machine optimized.
  • a transmission gear or reduction gear can be realized in a simple manner by appropriate adaptation of diameters of the pulleys.
  • the second pulley has a larger diameter than the first pulley. This makes it possible to realize a reduction gear. If a certain angle of rotation is adjusted on the handlebar device, for example by rotation on the steering wheel, then this reduction gear will cause the corresponding caused angle at the front wheel device to be smaller.
  • the second pulley is rotatably mounted on a carrier which holds the front wheel means.
  • On the support can be arranged in a simple manner a pivot bearing or integrate into this. It can be absorbed relatively large forces.
  • the torque transmission device comprises a reduction gear.
  • a steering control in particular with respect to cornering can be performed in a simple manner for an operator.
  • a gear ratio is in a range up to and including 1: 4.5. It is, for example, in the range of 1: 2.
  • a gear ratio of 1: 2 means that when turning the handlebar assembly by a certain angle, it causes the front wheel assembly to rotate by the corresponding half angle.
  • an axis of rotation of the front wheel device for a steering is parallel spaced apart from an axis of rotation of the handlebar device. The torque transmission device must then bridge this distance. This can be done in a simple, low-wear manner, for example via a toothed belt device. It can thereby achieve an optimized use of space.
  • the cleaning tool device is positioned between the front wheel device and the rear wheel device and is in particular positioned below the chassis.
  • the available space can be used optimally.

  • the lifting device comprises at least one rod which is articulated on the chassis.
  • a lifting device can be realized in a simple manner, which has to absorb relatively small forces. The majority of the forces can be absorbed by the carrier (and the corresponding holding device) and removed into the chassis. It can then form a lifting device, which provides essentially only a drive for a lifting movement or lowering movement and optionally provides an abutment which prevents, for example, a tilting of the cleaning tool device.
  • the at least one cleaning tool is a brush and, for example, a scrubbing brush or sweeping brush.
  • the cleaning tool is rotatably driven and rotationally driven in a cleaning operation.
  • the chassis forms a unit which is made of a plastic material.
