Definitions

  • the invention relates to a loader with a loader rocker and arranged on the loader rocker tool carrier or tool, wherein the tool carrier or the tool is connected at a first pivot point with the loader rocker and at a second pivot point with a pivot linkage, wherein the pivot linkage a first and a second Handlebar includes, which are pivotally connected to each other at a first link point and wherein the first link at a second link point on the loader link and the second link at a second link point at the second pivot point are pivotally connected to the tool carrier or the tool, further comprising a sensor is provided, by means of which a pivot angle between the tool carrier or tool and loader rocker is detected, wherein the sensor is positioned in a cavity on the loader and an actuating device is arranged for the sensor, which is partially out of one of the cavity formed opening and connects the sensor with the pivot linkage.
  • the JP S64 57150 U discloses a wheel loader with a loader rocker and a loader bucket, the pivoting angle of which is detected by an arranged on the loader rocker and with a pivot joint of the loader blade associated angle sensor.
  • the JP 2000 054423 a front loader with a control system for monitoring a loader tool, in particular a loader bucket.
  • the front loader includes a loader arm which is lifted by hydraulic cylinders.
  • a supercharger tool is provided at the end of the loader, which is pivotable about another cylinder. The swivel angle on the supercharger tool is determined by means of a sensor in response to an actuation of the supercharger.
  • Loaders such as front loaders, wheel loaders, telescopic loaders, rear loaders and the like are known. It is also known to provide such loaders with a sensor device, by means of which a pivoting angle of the loader arranged tool carrier or tool is measured, wherein the pivot angle indicates a pivot position of the tool carrier, in particular relative to a loader arm or a boom of the loader.
  • the arrangement of a sensor device on the loader is often difficult or expensive, since the sensor can be exposed to considerable stress and in particular must withstand soiling and damage due to load and must be correspondingly robust trained or protected.
  • magnetostrictive sensors are arranged directly on a lifting cylinder of the supercharger, so that the stroke of the cylinder can be measured and can be deduced from the swivel angle on the tool.
  • Magnetostrictive sensors are usually expensive to install and correspondingly expensive.
  • rotation angle or rotation sensors on the loader, for example on the loader rocker, on the tool carrier or on the pivot linkage of the loader.
  • the sensor must be additionally protected, for example by a robust cover.
  • a cover can on the one hand limit the view of the tool, on the other hand, it causes additional installation and cost.
  • the object underlying the invention is seen in a front loader of the type mentioned in such a way that the above problems are overcome.
  • a front loader of the type mentioned above is formed such that the cavity is formed in the loader rocker, wherein the loader rocker on its inner side at a swing member in the region of the pivot linkage has the opening in the wall of the loader rocker, access to the cavity in the loader swing forms.
  • the fact that the sensor is arranged in a cavity on the loader this is protected by external influences, or automatically covered, so that externally acting objects have no access to the sensor.
  • the assembly is also easy, since no additional covers are required.
  • the cavity is preferably sought near the pivot linkage, so that the actuator can be made compact and a pivoting movement can be recorded and measured directly on the tool carrier or on the pivot linkage. This avoids inaccuracies and minimizes error tolerances.
  • the sensor may be formed, for example, as a magnetic, potentiometric or optical rotation angle sensor or rotation sensor or rotation sensor.
  • the cavity is formed in the loader rocker near the pivot linkage.
  • the loader arm or a boom may be formed as a hollow profile, so that the opening is formed as a section of a hollow profile wall.
  • the assembly also designed as simple and straightforward.
  • a wiring for the sensor can be guided through the interior of the hollow profile, so that protection against damage from outside for the sensor and the wiring is given.
  • the senor could also be positioned in a cavity of the pivot linkage or the tool carrier, for example, between two spaced arms or support plates, wherein the opening is formed either by a recess on the handlebars or support plates or by the spacing of Leneker or support plates to each other.
  • the actuating device comprises an axis of rotation connected to the sensor, a rotary lever and a control arm, wherein the rotary lever is rotatably connected to the axis of rotation and the control arm pivotally connects the rotary lever with the pivot linkage.
  • the axis of rotation serves as a rotary encoder or - transformer for the sensor and can be connected directly or indirectly, for example by a rotation angle translation with the sensor.
  • the rotary lever is designed as a rigid connecting arm to the axis of rotation and extends radially to this.
  • the rotary lever thus transmits a movement exerted on the rotary lever movement directly on the axis of rotation.
  • the control arm which is designed as a pivotable arm or as a connecting rod, a movement of the pivot linkage is transmitted to the rotary lever by this or this at a connection point with the pivot link on one of the links and on a another connection point is pivotally connected to the rotary lever, so that a pivoting movement of one of the links of the pivot link in a pivoting movement of the rotary lever and thus in a rotational movement of the axis of rotation is transmitted.
  • the control arm may be connected to the first link of the pivot link and connects it to the rotary lever. This ensures a compact design of the actuator, since the first link directly with the Loader rocker or is connected to the boom and thus the opening of the cavity can be formed in close proximity to the pivot linkage.
  • the mounting plate By a mounting plate to which the sensor is attached and the axis of rotation mounted, also a simple assembly can be ensured because the sensor and the actuator can be pre-assembled and then the entire assembly conveniently as a compact component assembly on the mounting plate in the region of the opening by a few Mounting steps can be placed.
  • the mounting plate is fastened in the region of the opening of the cavity in such a way that the axis of rotation extends through the opening.
  • the mounting plate and the opening may for example be oval-shaped, oblong-shaped or rectangular, with mounting holes on the longitudinal sides (long sides) of the opening and threaded holes on the transverse sides (short sides) of the mounting plate are formed.
  • the opening By rotating the mounting plate after insertion into the cavity relative to the opening, the opening can be bridged by the mounting plate in the transverse direction to the longitudinal sides of the opening so that the transverse sides of the mounting plate protrude beyond the longitudinal sides of the opening (bridging the opening in the transverse direction) that an attachment of the mounting plate by, for example, screwing to said holes and without additional aids, eg Mounting bracket, mounting straps or the like can be done.
  • the loader can be designed as a front loader, wheel loader, telescopic loader or rear loader, wherein the loader rocker is designed as a loader swing of a front loader or wheel loader or as a boom of a telescopic loader or rear loader.
  • Front loaders and rear loaders can be used on agricultural tractors or construction machinery as attachments.
