Description

Known frameless brush for cleaning the windshield of a vehicle, consisting of a working sheet, in the body of which, on both sides, channels with nozzles are made along the entire length with the ability to provide different modes of fluid supply under the working edge of the brush in the direction of travel [1].
The disadvantage of this device is that the operation of the brush requires a complex control system for the modes of supply of washing liquid. This makes the device unreliable and expensive, and therefore limited in use. In addition, the springy element has a preliminary calculated curvature, which causes uniform brush pressing against the glass. However, the presence of channels in which an alternating liquid pressure is created depending on the operating conditions changes the moment of inertia of the cross section, therefore, changes the elastic characteristics of the power element, which leads to a change in the clamping force along the length of the brush and, therefore, to a decrease in the quality of glass cleaning from pollution.
Known frame brush for cleaning the windshield of a vehicle, containing rocker arms with an attached elastic scraper, to which an elastic tube with nozzles arranged uniformly along the length for supplying washing liquid under the brush scraper is attached on both sides [2]. This invention is taken as a prototype.
The disadvantage of this device is that the tube attached to the rocker arms is an elastic element that creates additional resistance to the clamping force that changes when the fluid pressure is created. This leads to a deterioration in the uniform adherence of the brush to the surface being cleaned, and, consequently, to a decrease in the quality of cleaning the glass from dirt. In addition, the supply of washing fluid is carried out simultaneously on both sides of the elastic scraper, while behind the brush, liquid sprayed on the glass remains behind the brush, which reduces visibility from the driver's seat, which reduces reliability in driving.
The aim of the invention is to increase the efficiency of the wiper.
This goal is achieved by the fact that the beam, on which the distribution arms holding the elastic scraper are fixed, is made to rotate relative to the brush body, on which the nozzles are fixed, in the plane of the glass around the axis connecting the ends of the beam and the body on one side, and on the other hand the brush has a movable connection, consisting of a sleeve fixed to the end of the rocker arm and a rod passing through the hole of the sleeve fixed at the ends symmetrically located relative to the body nshteynah. Moreover, the sleeve has a hole in the form of a groove.
When the wiper blade moves from the extreme position, the housing rotates relative to the rocker arm to the stop with the bracket, which allows nozzles mounted on the housing to move into the area in front of the elastic scraper along the brush and to turn on the windshield when the pump is turned on. This ensures the intensification of the process of destruction of the adhesive bonds of the mud layer with the surface, which makes it easier to clean the dirt from the working edge of the scraper. In such a fixed position of the rocker arm relative to the body, the brush moves along the surface of the glass to its extreme position, where the wiper changes its direction of movement. In this case, the rocker with an elastic scraper remains without movement until the body with nozzles, driven by the wiper arm, moves to the zone in front of the elastic scraper along the brush until the bracket with the rocker rests. The described process is repeated automatically with or without liquid, for example, with heavy rain. The pressing and stable position of the rocker arm with a fixed elastic tape relative to the surface of the windshield is ensured by axial connection to the housing perpendicular to the surface to be cleaned and the rod and sleeve are movably connected in a parallel plane, where the rod prevents movement of the rocker when it moves in the bore of the sleeve. The hole in the sleeve is made in the form of a groove, which allows you to compensate for the rotation of the rod in the hole that occurs when moving around the circumference of the brush housing relative to the beam.
The automatic process of turning the housing with nozzles relative to the rocker arm is due to the difference in the friction forces arising in the movement of the brush along the windshield. It is known that the coefficient of friction of rest of rubber on glass is determined by the value of 0.5-0.6, and the coefficient of friction of steel with plastomers is determined in a wider range, for example, for F-4RM modified fluoroplastic - 0.04, for textolite - 0.3. Therefore, the arising friction force, which must be overcome in order to bring the two contacting bodies into motion relative to each other, will be different, that is, the friction force between the elastic scraper and glass will be greater, and between steel and plastic less. Therefore, with the same force of pressing the brush against the glass, the force required to rotate the housing relative to the rocker arm is required less than the force of movement of the elastic scraper on the glass, which determines the sequence when the movement starts.
Thus, the proposed technical solution allows the glass to be cleaned from dirt more efficiently, i.e. to ensure the supply of washing liquid to the area in front of the brush in the direction of travel and at the same time ensure reliable and uniform pressing of the elastic scraper to the glass under various cleaning modes.
The wiper blade is shown in FIGS. 1-5.
Figure 1 shows a General view of the brush; figure 2 - diagram of the projection of the nozzles on the glass with the movement of the brush; figure 3 is a view And the reference node; figure 4 is a section bb of the support sleeve of the rocker arm; figure 5 is a section bB axis of the support node.
The wiper blade of the vehicle consists of a housing 1, which is connected via an adapter 2 to the wiper arm 3. An elastic tube 4 is attached to the wiper arm for supplying washing liquid to nozzles 5 located uniformly along the entire length of the housing 1 and lying in a plane perpendicular to the surface of the windshield. The rocker 6 is connected at two ends to the housing 1 by means of movable units. On one side of the rocker 6 is connected to the housing 1 by an axis 7 located perpendicular to the plane of the glass, with the possibility of rotation of the rocker 6 relative to the housing 1 in the plane of the windshield. On the axis 7 between the supporting planes installed thrust sleeve 8, made of plastomer. On the other hand, the rocker 6 is connected to the housing 1 by means of a sleeve 9 with an opening in the form of a groove made of plastomer and fixed at the end of the beam 6, and a rod 10 inserted into the hole of the sleeve 9 and fixed with its ends with brackets 11 located symmetrically at the end the housing 1 on each side parallel to the plane of the glass. Small rocker arms 12, on which an elastic scraper 13 is fixed, are hinged to the beam 6.
The wiper blade of the vehicle operates as follows. During operation, the wiper arm 3 through the adapter 2 transmits the pressing force from the housing 1 to the beam 6 through the movable nodes. On the one hand, through the thrust sleeve 8, located on the axis 7, and on the other hand, through the rod 10, resting on the sleeve 9. In this case, the pressing force of the elastic scraper 13 against the glass is distributed evenly by the small rockers 12 along the entire length. When the wiper rotation drive is turned on, the lever 3 through the adapter 2 sets the movement to the housing 1. At the moment of the start of movement, the housing 1 rotates relative to the rocker 6 on the axis 7, and the rod 10 moves along the groove of the sleeve 9 to the stop of the bracket 11 with the rocker 6. At the same time, the nozzles 5, located on the housing 1, are moved to the area in front of the elastic scraper 13 along the brush. When you turn on the pump, the fluid enters through the tube 4 and through the nozzles 5 wets the surface of the windshield. Further movement of the brush drives the rocker 6 in a fixed bracket 11 position relative to the housing 1 along the glass, and the elastic scraper 13 cleans the dirt with the working edge and moves it outside the extreme positions of the wiper path.
The use of this invention will allow better cleaning of the contaminated surface of the windshield and improve reliability in driving.
