Abstract

A device to be placed on the tractor allows the supply of rotary energy or electric energy to the tractor or also to attachments and mounted implements.

Description

Accumulator-assisted device for tractors
BACKGROUND OF THE INVENTION
Tractors for agricultural use are usually designed for low speed and high tractive power.
In the course of the spread of purely electric drives for passenger cars, it is naturally obvious to realize this also for agricultural vehicles and implements, especially since photovoltaic solar generators are also available in many cases for favorable charging in the agricultural sector.
In the field of passenger cars, the combination with internal combustion engines as hybrid drives is declining because the need for a reserve is hardly necessary with increasing battery performance.
However, the situation is different in agronomic applications: Here, high power is occasionally required when towing implements, but often only comparatively short distances are driven and the distance to the charging point is therefore short in each case.
It therefore makes sense to leave the power of the diesel engine in full, but to supplement it with an electric drive for a large number of applications requiring medium power.
TASK OF THE INVENTION/PROBLEM TO BE SOLVED
The task of the invention is therefore to develop a type of tractor that meets these requirements.
SOLUTION
An inventive step to this end is to arrange an additional battery pack in such a way that it can be changed easily and quickly. This is possible at all implement attachment points on the tractor, especially at the front and rear power lift with which it can be picked up and, if necessary, also put down.
The further inventive step is then to also arrange an electric motor there and to couple its shaft to the power take-off shaft. The power take-off shaft is normally only used for power output, but it can be used reversibly. This simplifies the design considerably.
Another inventive step is to install the electric motor either together with the battery as a single unit or in a dissolved design. In this case, the battery and electric motor are mounted separately, e.g. the battery in the front linkage and the motor in the rear linkage.
The diesel engine of the tractor runs constantly during its operation, first to generate the power if more of it is needed than the electric motor delivers, second to operate all auxiliary drives (compressed air, alternator, hydraulics etc). The tractor is supported by the electric motor and thus becomes a hybrid vehicle.
When the battery is empty, the tractor runs normally with the internal combustion engine, and there is no need to rely solely on the electric drive at any time.
Furthermore, attachments and mounted implements can be supplied with electric power or rotary power via a power take-off shaft.
CONTROL OF THE ELECTRIC DRIVE
The electric motor is controlled directly by the tractor via a connection to the vehicle control system.
Furthermore, it is also possible to charge additional batteries in case of favorable electricity prices or high production output of the own energy production and to use them alternately on the tractor.
