Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of electric windscreen wiper on locomotive.
Background technology
Rain brush is also called Windshield Wiper, water is dialled, wiper or windscreen-wiper, is used to strike off the equipment being attached to raindrop in vehicle windscreen and dust, to improve the sight line of steerman, increases traffic safety.Because legal requiremnt, nearly all self-propelled vehicle is all equipped with rain brush, and the vehicle rear window lifting vehicle such as the back of the body car and Recreational Vehicle etc. is also equipped with rain brush, and except automobile, other transportation meanss are provided with rain brush too, such as train, motor-car, electric car etc.
Existing rain brush is generally made up of common DC motor, worm-gear speed reducer and double leval jib driving device, and such as Chinese patent literature data discloses a kind of electric windscreen wiper for locomotive [application number: 200710055396.X, Authorization Notice No.: CN101020447B], it comprises DC machine, and the turbine worm reducer structure to be driven by DC machine, crank rocker transmission device, rain brush assembly and speed regulation device thereof, the stator of DC machine is made up of four block permanent magnets, the commutator of motor is arranged in the back end cover for motor of rotor rear end, four are provided with motor shaft to perpendicular carbon brush nest in the side of back end cover for motor, at carbon brush nest built with carbon brush, carbon brush lower end contacts with commutator, carbon brush lid and carbon brush nest thread connection is provided with in the upper end of carbon brush nest, the centre of carbon brush lid is provided with adjusting screw(rod), spring is provided with between adjusting screw(rod) and carbon brush, the motor shaft of rotor leading portion is provided with built-in fans, and breather port is respectively arranged with on motor front end cover and rear side housing.
But the angle requirement that different vehicles swings for rain brush is different, need to regulate the pendulum angle of rain brush for different vehicles.And what adopt due to existing rain brush is crank rocker transmission device, the crank rocker that angular adjustment just must change corresponding size just can realize.But the finite volume of rain brush, change very inconvenient, not only dismounting trouble, replacement cost are high, and crank rocker transmission device kinetic energy loss in transmission process also very greatly, thus can have impact on the service life of rain brush.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, provide a kind of pendulum angle easy to adjust, the electric windscreen wiper of long service life.
Object of the present invention realizes by following technical proposal: a kind of electric windscreen wiper, comprise base, the servomotor of reductor and the work of drive reductor, it is characterized in that, described base is provided with angle regulator, described angle regulator comprises housing and the internal induction circle that is arranged in housing and outer induction coil, described reductor is arranged on angle regulator and the S. A. of reductor stretches in angle regulator, described S. A. is connected with bearing two by bearing one with between housing, internal axle sleeve is provided with in described S. A., described internal axle sleeve one end is stretched in S. A., the other end has the pedestal of outwardly convex, described internal induction circle is fixed on pedestal by screw, it is outer and be connected mutually by screw between outer induction coil and housing that described outer induction snare is located at internal induction circle, described internal induction circle offer two positioning grooves and be filled with magnetics in two positioning grooves, described outer induction coil offers through hole one and through hole two, described through hole one and through hole two are provided with inductor and inductor passes outside, output shaft is provided with and output shaft extends outside the base in described internal axle sleeve.
The servomotor of this electric windscreen wiper drives reductor work, and the S. A. that output shaft and internal axle sleeve follow reductor rotates, and the internal induction circle be arranged on internal axle sleeve also rotates thereupon.When the positioning groove that on internal induction circle, is filled with magnetics rotates to one of them the inductor place being arranged at outer induction coil, one of them inductor transmits, and now servomotor starts reversion; When after reversion, another positioning groove rotary setting being filled with magnetics is when another inductor place of outer induction coil, another inductor transmits, and servomotor reverses again, thus realizes swinging of wiper.Therefore the angle difference between two positioning grooves to center on internal induction circle can make the pendulum angle of wiper different.When running into different automobile types and needing to regulate the pendulum angle of rain brush, only need replace corresponding internal induction circle, its pendulum angle is regulated and not only facilitates, and replacement cost be low.
In above-mentioned a kind of electric windscreen wiper, described internal induction circle has the engaging lug be connected with pedestal, the outer wall of described internal induction circle has the limiting stopper of outwardly convex, the inwall of described outer induction coil has the step groove for limiting stopper activity.Limiting stopper is movable in the region of step groove, and when running into special permission situation, step groove can stop limiting stopper, avoids the excessive rain brush caused of its pendulum angle to damage, thus its service life is increased.
In above-mentioned a kind of electric windscreen wiper, described S. A. one end has the axis hole that stretches into for internal axle sleeve and axis hole is conical design, and one end that described internal axle sleeve stretches into axis hole is also for conical design and internal axle sleeve and axis hole are flush fit.Conical design and flush fit assembling make closely to be connected between internal axle sleeve with S. A., avoid rotate cause loosen.
In above-mentioned a kind of electric windscreen wiper, on described S. A., between bearing one and bearing two, place is arranged with outside framework oil seal.
In above-mentioned a kind of electric windscreen wiper, described output shaft is positioned at internal axle sleeve inferior portion and is provided with outer shaft, described outer shaft extends outside the base.
In above-mentioned a kind of electric windscreen wiper, described reductor and the top of servomotor are provided with a top cover, are provided with service cover in the middle part of described top cover.Arranging of service cover can make its maintenance more convenient.
In above-mentioned a kind of electric windscreen wiper, described reductor is planet-gear speed reducer.Planet-gear speed reducer has the advantages such as volume is little, precision is high, efficiency high noisy is low.
Compared with prior art, the internal induction circle of this electric windscreen wiper is provided with the positioning groove that two are filled with magnetics, through hole one in outer induction coil and through hole two are all provided with inductor, the rotation of internal induction circle can realize swinging of rain brush, and the angle swung is determined by the angle the positioning groove to center of two on internal induction circle, therefore only need replace corresponding internal induction circle can realize angular adjustment, makes its pendulum angle easy to adjust.The rain brush that limiting stopper on the inwall of the limiting stopper on the outer wall of internal induction circle and outer induction coil can be avoided artificially or outside cause causes excessively swings and impacts the service life of rain brush.
