Abstract
The utility model discloses an electric windscreen wiper which is composed of an electric motor subassembly, a drive subassembly, a wiping subassembly and a control subassembly, wherein A box body (24) of the drive subassembly is the main body of the utility model, and the shape and the volume of the box body are suitable for corresponding space given by a locomotive. The utility model has the advantages of reliable performance, convenient installation, convenient maintenance, low locomotive space occupation, low noise, beautiful appearance, high wiping degree, etc.
Description
Utility model relates to the wiper device that uses on a kind of diesel locomotive, the electric locomotive windscreen.
The rain brush overwhelming majority on the existing locomotive of China all adopts 1 year generation technique and the new type pneumatic wiper produced, though also once improved to some extent for a long time, but do not break away from existing unsurmountable drawback of new type pneumatic wiper self and defective all the time, as: stability is poor, must strict seal could guarantee to use; It is unreliable, easy to failure to control; Noise is big, and service life is short, needs often maintenance and replacing; Move insensitively, reaction is slow; Pipeline connects loaded down with trivial details, easily leaks gas etc.Along with science and technology development, every performance of locomotive improves constantly and upgrade, and has only on the level that Wiper system still rested on for the 60 to 70's, and this must influence the performance of modern locomotive overall performance.
The purpose of this utility model is to provide a kind of can overcome the many deficiencies of pneumatic rain brush, reaches modern locomotive at a high speed and the electric windscreen wiper of the usage condition of continuous working from every performance and structure.
The utility model by motor branch unit, transmission branch unit, scrape the moisture assembly, four of branch units of control part is formed.Transmission branch unit casing is this device main body, and its shape and volume are as the criterion with the corresponding space that adapts to locomotive and provide.The mode that transmission branch unit casing back fixed electrical machinery branch unit, its front adopt the keyway location and be threaded, fixedly Windshield Wiper assembly and rain brush branch unit.Its motor branch unit is by motor shaft, ratio wheel, output shaft, electric machine casing, decelerating casing, carbon-brush holder assembly, enameled wire loop iron core, permanent magnetic tile, carbon brush, graphite oilless sintered-metal bearing, bearing compressing tablet and contains parts such as assembling screw, brush carrier plate and reducer shell bonnet that hairfelt, insulating end plate, commutator screw thread suspension hook, assembling screw, steel ball, adjustable screw, setscrew nut and transmission gearbox fix, return plate, file protect and assemble.In its transmission branch unit casing " four-bar linkage " drive mechanism is housed, a rectangle groove is opened on the last plane of casing, and a skewed slot is opened in the back.It is scraped the moisture assembly and is made up of brush arm, brush sheet, pitman, brushes sheet and is fixed on the brush arm by pitman.Its electric switch control branch unit is connected in the locomotive on the power supply by push pull switch or rotor switch, passes through 1.5mm then
2The BVR lead links to each other with 110V motor pig-tail wire by the design's schematic diagram, and switch and lead respective fixation can be opened or close.
The utility model is owing to adopt the electronic control rain brush of permanent magnetism double speed, from having overcome many deficiencies of pneumatic rain brush in essence, has dependable performance, installation and maintenance are easy, occupies that the locomotive space is little, noise is low, aesthetic in appearance, scrapes the cleanliness advantages of higher.
