Definitions

  • the invention is about linear wiper system used to clean rain, snow, ice, washer fluid, water or residues from the windows of military vehicles and allowing the driver to see the road better.
  • the invention is primarily about a linear wiper system involving drive that allows cleaning of the windows by moving the timing belt and thus the wiper arm by moving the idler gear wheel, with a wiper arm that thoroughly cleans the rectangular vehicle glass with its linear motion.
  • the wiper system in automotive vehicles is an indispensable system for the driver to have road dominance in various weather conditions. It is an auxiliary automotive system ensuring cleaning the outer surfaces of the vehicle windows, which are the transition zone between the driver and the outside environment, in a driver friendly way.
  • Traditional practice in automotive vehicles is depending on the principle that scanning an area on the glass with a circular motion of the wiper arm or arms and cleaning the glass with the rubber parts on the wiper arms during this scanning process.
  • a water spray system to be used when necessary is also available as a sub-system in order to assist in this cleaning process.
  • wiper arms For each complete revolution of the wiper motor, wiper arms complete a reciprocating tour in their "section circular" motions. Changing wiper system speed settings when necessary is also ensured by changing revolution speed of this driving motor. Expectation from a wiper system is that it can provide maximum clean sight to driver. Critical vision areas for the driver are defined in the regulations prepared for this purpose and also minimum wiping performance values set in these areas. This shows how vital the issue of clean field of vision is. Because when the driver loses his/her vision towards the outside of the vehicle or in case of weakness in this capability, it is possible that accidents will occur and the accidents will cause loss of life and property. Wiper arms in today's automotive wiper systems modes circularly. This, in fact, causes dirty areas that cannot be wiped off on a rectangular-like vehicle glass.
  • Windshield wipers in civil autos for the purpose of decreasing these dirty areas have been designed with 2 arms.
  • one of the determining factors is the side lengths in glass' rectangular like geometry.
  • glass heights and widths in civil automotive vehicles allowing the performance of circular wipers to be at a good level
  • Glass dimensions in armored military combat vehicles exhibit serious differences compared to civilian vehicles.
  • driver's glass geometry is in the form of a rectangle with a low height but a proportionally larger width.
  • the length of wiper arms in wiper system determines glass height being this short side.
  • This wiper arm length in fact will be the radius value in the scanning area performance to perform revolving motion. This means that a short radius will result with a smaller scanning area.
  • a wiper performance like in automotive cannot be achieved in glass with a long width edge versus the short one in height or we need more wiper arms and therefore a more complex system in order to achieve this.
  • Length and number of the wiper arms can ensure that the total surface area of the glass can be wiped from 60% to 70%.
  • visibility in military armored combat vehicles that will perform vital operations is of greater importance even on a centimeter basis.
  • the current system is about a linear wiper system developed to eliminate the disadvantages mentioned above and to bring new advantages to the related technical field and used to clean rain, snow, ice, washer fluid, water or debris from military vehicles' windows and allows the driver to see the road better.
  • Our invention is called linear wiper system in military vehicles.
  • the primary essential feature of the invention is that in a wiper system to be used in military vehicles, the wiper arms move on the glass linearly, not circularly as in conventional systems. Due to the large proportional differences of the long and short sides in glass geometry in military vehicles with the wiper arm having to be short scanning area remains low with circular motion. This causes the clear field of view offered to the user on the glass to be less.
  • the wiper arm can scan almost the entire surface area of the glass with a linear motion.
  • the most important aim of the invention is to make system operation simpler by reducing the number of moving parts.
  • the 4-arm mechanism transmitting the drive force from the engine to the wiper arms in the conventional wiper system is no longer needed.
  • Another important aim of the invention is to eliminate situation of "positioning the wiper motor and mechanism inside the vehicle", creating a disadvantage in the conventional wiper system for military vehicles. Because with this invention, while removing the moving mechanism parts, system elements of the invention can be positioned outside the vehicle. Thus, the parts transmitting the motion between the vehicle interior and exterior are also eliminated and the weakness induced by the vehicle ballistic protection is eliminated. In addition, the less is transitions between the interior and the exterior of the vehicle, the greater the sealing capability will be. In addition to positioning outside the vehicle, system parts can also fit in a smaller volume.

  • Our invention generally comprise, a drive (10) providing the motion in the system, preferably 2 idler gear wheels (20) transmitting the motion at the drive output and at the other end of the system, the timing belt (30) seating on these idler gear wheels (20) with the same tooth pitch, a rail (40) enabling a bearing for the primary motion of the wiper arms (110) in the system, preferably 2 cars (50), which move in this rail and on which the wiper arms (110) are attached, belt holder lower body (60) holding both the belt and the wiper arms, between the car and the wiper arms, wiper arm carrier upper body (70), belt tension system cover (80), belt tension piece (90) and tension adjustment screw (100).
  • These parts constitute system's movement mechanism.
  • elements necessary for the electrical side of the system constitute one control module (120) and magnetic sensors (130) that can be used as an alternative design when necessary and metal parts (140) that these sensors face.
  • our invention is primarily based on installing a drive (10) - timing belt (30) to move these cars (50) with the connection of 2 wiper arms (110) preferably on 2 cars (50) positioned on a rail (40).
  • This invention is designed with 2 wiper arms (110) since there are 2 separate windows in front of the vehicle.
  • the design wiper arm (110) and thus the number of cars (50) can be increased by 1, 2, 3...etc. depending on the number of windows.
  • a drive (10) is preferably used in our invention.
  • the drive speed (10) should not be very high, but its torque should be high. It is important that the drive (10) torque is high because of reasons such as pollution on the glass, snow / ice formation, heavy dust / sand accumulation, freezing and sticking of the glass and wiper rubbers. Since the wiper system is a friction system, these friction forces must be at a level that can be easily met by the drive (10). Therefore, the torque is enhanced by decreasing the drive (10) speed preferably with a reducer.
  • the electronic control of this drive (10) is very important in the electrical control of the system, that is, for the wiper to move back and forth on the glass at the start and end points.
  • the drive (10) is chosen with an "encoder" on it.
  • amount of rotating the drive (10) in the wiper mechanism motion and thus the position of the wiper arms can be identified.
  • this wiper system in one revolution of the drive, the wiper arms do not meet a 'forward and back' cycle. Therefore, it is more difficult and critical to identify the starting and ending positions of the wiper arms during motion.
  • the drive (10) is not selected with an encoder, and preferably two magnetic sensors (130) can be positioned on the system.
  • Magnetic sensors (130) have been selected in our invention in fact it can be selected as a button / switch or in other features.
  • metal pieces (140) are placed on the timing belt (30) for the reading these magnetic sensors (130) positioned at the start and end points of the system. With the motion of the timing belt (30), these metal parts (140) are seen by the start and end magnetic sensors (130), respectively.
  • Our invention can rotate clockwise or counterclockwise according to the current polarity on the drive (10).
  • the current polarity is reversed, it rotates in the opposite direction of the direction it rotates.
  • the drive (109) tries to turn in the opposite direction.
  • wiper arms (110) have a force load on the drive (10).
  • this force load is in the form of momentum.
  • the drive (10) suddenly overcomes this momentum and tries to reverse. But this instant loading can damage the mechanical parts inside the drive (10).
  • the vehicle ECU or an additional separate motor driver module (120) gives direction change commands to the drive (10), it is necessary to apply soft stop and soft start.
  • the load on the drive (10) will first be reset by braking, and then instant loads on the internal parts will be protected with a safe start.
  • the motor driver module 120 has a critical importance in terms of system service life.
  • the idler gear wheel (20) compatible with a timing belt (30) is connected to the shaft at the output of the drive (10) and circular motion on drive (10) made suitable to be transferred to the system.
  • One of the same idler gear wheels (20) is placed at the trailing end of the system and a timing belt (30) surrounding these 2 idler gear wheels (20) completes system's motion transmission.
  • a rail (40) is placed in this motion area and system's motion bearing is formed accordingly. In this way, the timing belt (30) mechanism, which actually rotates around a rail (40), is obtained.
  • a car (50) is placed on this rail (40) for each wiper arm (110).
  • the car (50) makes a linear movement back and forth within the rail (40) with the motion it takes from the timing belt (30).
  • the wiper arm (110) moving together with this car (50) also cleans the glass.
  • a part connecting the car (50) and the timing belt (30) is needed.
  • This part is designed as a belt holder lower body (60). While the lower surface of this part is connected to each other with the car (50), the tooth steps on which the timing belt (30) will seat are processed on its inner surface.
  • the connection between the timing belt (30) and the cars (50) is established thanks to this part.
  • the rectangular vehicle glass is fully cleaned by the linear motion of the wiper arm (110).
  • the upper body (70) and the tension system cover (80) ensure the timing belt (30) to be fixed on this lower body (60).
  • the upper body (7) actually takes the timing belt (30) between it and the lower body (60). While the upper body (7) carries a stud part on it, allows the wiper arm (110) to be mounted on this part.
  • timing belts (30) are generally produced in a closed circle in a ready full length.
  • an open-ended strip-shaped timing belt (30) is used instead of producing a fixed-length special timing belt (30).
  • a cost-effective belt solution is obtained.
  • Timing belt (30) tension is ensured by the belt tension piece (90) located between the lower body (60) and the tension system cover (80) by keeping position of 2 idler gear wheels (20) in the system fixed.
  • Belt tensioner (90) can slide between the lower body (60) and the upper body (70). By means of a tension set screw (100), this belt tensioner part (90) is pushed forward to increase the tension of the timing belt (30). This design provides advantages both in maintenance and repair, cost and assembly- disassembly processes.
