Description

Introduction to the structure

Radiator shutter with automatic end position switch-off .

The radiator surface of a water-cooled "engine" consists of a trachea and vertical lamellas in which the coolant is located, as well as the upper and lower flasserkaete of the cooler constantly exposed to the wind in order to achieve a cooling effect of the circulating water, which is also necessary. In the colder months of the year, however, some of the radiator surface in question is temporarily covered in order to achieve the opposite, namely less strong cooling of the: fenden surface and thus a faster heating of the cooling water and thus the engine temperature.

As is well known, the cheapest “opera door” motor is between 70 - 80 ° and the sooner this is reached, the more wear-reducing it has on the engine.

Despite the thermostat control, which only releases the water return from the engine to the radiator only when the corresponding temperature of 70 - 80 ° has been reached, the radiator is always exposed to the correspondingly lower temperatures and any possible contamination ( Snow, ice, rain, dust, etc.) before a correspondingly higher temperature of the water or coolant has been reached. A vehicle that is not in operation, which is therefore standing for a long time, still has the disadvantage that its radiator surface is unprotected against any weather; -feeding is exposed and it can absolutely here to Vereisu "gi""ER \ half of the air tubes and fin" by vo "ausse" penetrating moisture coming, leading to eventual radiator damage in Fora vo "Uadichtigkeite» »can. The consequences are then usually too little available coolant with subsequent overheating of the engine, etc. In order to counteract the negative phenomena listed above, liVfc the invention a ^ electrically operated radiator shutter with automatic end position shutdown, which is based either by touch ι

switch (3-stage) with switch positions »1 = up or down | closed, 0 rest position in every position of the radiator shutter and 2 = downwards or open, or fully automatic depending on the respective »engine temperature via a» thermal sensor i »connection can be operated with a relay, controlled by 1 tact switch.

The advantage of such a bucket Kuhier ^ aibufcie, 'lijegTK.eimdeutig DARIM that the radiator surface enclosed between the layer stehemJie'm ·' stay vehicle vo'l-letäjidig covered comb * and daait protected.

Only when the vehicle is put into operation and the engine has reached its operating temperature is it opened by a switch, or it opens automatically when the control environment is temperature-dependent. Another advantage is that the radiator louvre could be raised in every position from fully open to fully closed by means of a push-button switch so that it would not have to be successful when the bonnet was opened. The control panel ( green or red ) indicates the position is open or closed (Emdlage).

Operation of the radiator shutter with automatic ifind position switch-off .

In the previous list "components" was already more detailed entered into the same.

Assuming that the radiator shutter (Fig.1 No. 1) is in the open Position (lower end position) is located, has the same through guide bar (9) the lower limit switch (IO) is actuated and the power supply to the E. —iflOtöX "V, 5y ülioer-uruCheü, äOdsß dcfäclbc aDgcSCii & itet lät.

The green control lamp lights up and indicates the lower end position. When the push button is pressed (3-stage) stage 1 = upwards, becomes the power supply to the electric motor (3) is released, the upper shaft (2) is through the E. motor (3), which is screwed to the shaft (2), in Rotation offset and pulls the guide strip (9) in the U-guide rails (7) upwards via the flat belt (12). The tarpaulin (5), which is attached to the guide rail (9), is thereby from the lower The shaft (4) is unrolled and the further it is pulled upwards rolled up on the upper shaft (2).

The torsion spring (6) is tensioned by rolling off the lower shaft (4) and rolling on the upper shaft (2). If the guide bar ^) reaches the upper limit switch (IO), εο it detects the same, the power supply to the electric motor (3) is interrupted, the red control lamp lights up and shows the upper limit position and thus the closed state of the radiator shutter. When the pushbutton switch level 2 »down is pressed again, the power supply to the E _fc motor (3) is released again, but at the same time its direction of rotation is reversed via the pushbutton switch and the torsion spring (ö) tensioned when rolling up pulls the tarpaulin (5) from the upper one Return shaft (2) to the lower * elle (4). After reaching the lower limit switch (10), the contact is triggered again by the guide bar (9), the power supply to the electric door (3) is interrupted and the green control lamp indicates the lower limit position.

The pushbutton is activated while the tarpaulin is being rolled up and down (5) released, the radiator shutter remains due to the power failure to the E. motor ($) stand in the position just reached. By pressing the switch again! (Level 1 or Level 2) it can then either be operated up or down again, ois one of the limit switches has been reached

Water temperature according to the display. • Feiyjthjiirmo'me'fc / ire in the dashboard "The vehicle can be opened or closed without stopping and getting out and having to open the hood.

To move the radiator louvre (Fig. 1 No. 1) in different types of travel » To be able to install tools, it is considered to produce them in approx. 4 different sizes (truck and car).

By changing the width of the upper and lower uerschiene (8) (already provided by holes, Fig. 1) and by shortening the U-guide rails (7) in conjunction with the angle mountings (13), practically all heights and widths are one cooler surface gegeDen coverable _v and individual use.

if the Schieaen (7 and 8) are shortened, the waves (2 and 4) and the tarpaulin (5) are shortened in width. For this purpose, the guide rollers (11) are on the opposite side Side from the E. motor (3) and the torsion spring (6) removed, the shafts (2 and 4) shortened and the guide rollers (11) back on the shafts and stored again in the U-guide rails (7). According to the shortening of the shafts (2 and 4), the tarpaulin (5) also to be shortened in width.

The flat belt (12) is then in the middle of the continuous Guide bar (9) and in the middle of the rtelle (2) attached so that a horizontal rolling up and down takes place and there is no tilting of the guide strip (9) in the U-guide rails (7).

For reasons of corrosion resistance, all components with the exception of the 4 guide rollers (11), the electric motor (3) and the torsion spring (6) are made of high-strength plastic .

The E. motor and the torsion spring are sealed against splash water

All cable connections between the individual E. parts are accordingly To be insulated in a splash-proof manner and to be laid firmly.
