Abstract

In the case of a driver's seat for a tractor the seat (5), pedals (3) and steering wheel (4) are arranged on a common platform (2) which is spring-mounted relative to the chassis (6) by means of a spring arrangement (1). <IMAGE>

Description

Die Erfindung betrifft einen Fahrersitz in einem Kraftfahr­ zeug, insbesondere Traktor, das der Fahrer mittels Pedalen und einem Lenkrad bedient, wobei unterhalb des Sitzes eine den Sitz gegenüber dem Fahrzeugchassis abfedernde Federungs­ einrichtung vorgesehen ist und Pedale und Lenkrad über ein Strömungsmittel auf die betroffenen Fahrzeugteile einwirken.The invention relates to a driver's seat in a motor vehicle stuff, especially tractor, which the driver uses pedals and operated a steering wheel, one below the seat suspension cushioning the seat against the vehicle chassis device is provided and pedals and steering wheel over one Apply fluid to the affected vehicle parts.

Schon seit langem werden Servomechanismen verwendet, die von den Pedalen und dem Lenkrad bedient werden und die mit ei­ nem Strömungsmittel arbeiten, das über flexible Schlauchlei­ tungen zu den betroffenen Stellen hingeführt wird. Dadurch war es möglich, komplett gegenüber dem Fahrzeugchassis abge­ federte Fahrerkabinen zu entwickeln, insbesondere bei Trak­ toren, die einen großen Federweg zulassen und über Quer- und Längslenker auch Wank- und Nickbewegungen ermöglichen. Auf diese Weise war es möglich, bei Traktoren der oberen PS- Klassen die Sitze mit sehr flachen Federkennlinien und Feder­ wegen über 120 mm abzufedern, um die niederfrequenten Be­ schleunigungen und immer größeren Schwingungsamplituden auf­ grund der großen Fahrzeugmasse und der großvolumigen Traktor­ reifen auszugleichen, was bei der üblichen Abfederung des Sitzes allein nicht möglich wäre, da Relativbewegungen zwi­ schen Fahrersitz und Fußpedalen für Bremse, Kupplung usw. über 120 mm zu Fahrunsicherheiten führen. Gefederte Fahrer­ kabinen bzw. Fahrzeugkabinen dieser Art sind aber sehr auf­ wendig und teuer und haben noch die folgenden Nachteile:Servomechanisms that have been used by the pedals and the steering wheel are operated and with egg nem fluid work that over flexible hose to the affected areas. Thereby it was possible to completely offset the vehicle chassis to develop sprung driver's cabins, especially at Trak gates that allow a large spring travel and cross and trailing arms also enable roll and pitch movements. In this way it was possible to Class the seats with very flat spring characteristics and springs because of over 120 mm to cushion the low-frequency loading accelerations and ever larger vibration amplitudes due to the large vehicle mass and the large-volume tractor to compensate for the tires, which with the usual cushioning of the Seat alone would not be possible, since relative movements between driver's seat and foot pedals for brake, clutch, etc. lead to driving uncertainties over 120 mm. Suspended drivers  Cabins or vehicle cabins of this type are very open agile and expensive and also have the following disadvantages:

Die großen Federhübe verlängern die Fahrerkabine nach oben.The large spring strokes extend the driver's cabin upwards.

Es ergeben sich Festigkeitsprobleme, da die Fahrerkabinen auch den Überrollschutz darstellen.Strength problems arise because of the driver's cab also represent the rollover protection.

Da der Fahrer gegenüber äußeren Schwingungseinflüssen stark isoliert ist, verliert er während der Fahrt das Gefühl zur Fahrbahn. Es besteht die Gefahr, daß das Fahrzeug überstrapa­ ziert wird, da z. B. Schlaglöcher nicht mehr registriert wer­ den und die kritische Geschwindigkeitsgrenze überschritten wird.Because the driver is strong against external vibrations is isolated, it loses the feeling when driving Roadway. There is a risk of the vehicle being overstrained is decorated because z. B. Potholes no longer registered and exceeded the critical speed limit becomes.

Die Fahrerkabinen beschreiben eine sehr niederfrequente Bewe­ gung. Die gesamte Kabine schaukelt daher nur noch leicht und kann einen Fahrer "seekrank" werden lassen.The driver's cab describes a very low frequency movement supply. The entire cabin swings only slightly and can make a driver "seasick".

Der Erfindung liegt nun die Aufgabe zugrunde, einen Fahrersitz mit vergleichsweise geringe­ ren Kosten derart abzufedern, daß trotz großer Federhübe die Fahrsicherheit nicht beeinträchtigt wird.The invention is based on the object a driver's seat with comparatively low to cushion ren costs in such a way that despite large spring strokes Driving safety is not impaired.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Sitz, Lenkrad und Pedale auf einer Plattform unbeweglich zuein­ ander angeordnet sind, die gegenüber der unbeweglich mit dem Fahrzeugchassis verbundenen Fahrerkabine beweglich ist, wo­ bei die Federungseinrichtung die Plattform gegenüber dem Chassis abfedert.This object is achieved in that seat, Steering wheel and pedals immovable on a platform are arranged other than the immovable with the Vehicle chassis connected driver's cab is movable where in the suspension device, the platform opposite the Chassis cushioned.

In der Zeichnung ist die Erfindung veranschaulicht. Die übliche Sitzfederung 1 in verstärkter Ausführung wird mit einer Platt­ form 2 versehen, an welcher die Pedale 3 und das Lenkrad 4 befestigt sind. Heutige Traktoren der oberen PS-Klassen haben bereits die Entkoppelung der Pedal- und Lenkradsteuerung zwischen Fahrerkabine und Fahrzeug, um den Lärm in der Fahrerkabine zu vermindern. Diese Plattform 2 schwingt mit der Sitzfederung in gleichem Maße mit. Aus diesem Grunde können größere Schwingwege als 120 mm akzeptiert werden. Da nur der Sitz mit den Pedalen und dem Lenkrad abgefedert wird und das Umfeld, die Fahrerkabine, nicht mitschwingt, wird das Gefühl der Fahrbahnunebenheit wieder vermittelt und die Fahrsicherheit dadurch erhöht.The invention is illustrated in the drawing. The usual seat suspension 1 in a reinforced version is provided with a platform form 2 , to which the pedals 3 and the steering wheel 4 are attached. Today's tractors in the upper horsepower classes already have the decoupling of the pedal and steering wheel controls between the driver's cabin and the vehicle in order to reduce the noise in the driver's cabin. This platform 2 swings with the seat suspension to the same extent. For this reason, vibration paths larger than 120 mm can be accepted. Since only the seat is cushioned with the pedals and the steering wheel and the surroundings, the driver's cab, do not resonate, the feeling of the road unevenness is conveyed again, thereby increasing driving safety.
