Description
Art
The present invention relates to a kind of rain brush driver train, belong to vehicle wiper field, the especially hydraulicdriven wiper of flexible duct.
Background technology
At present, the rain brush driver train majority of the wiper on market catches up with transmission for connecting, and noise during its work is comparatively large, and, connect and catch up with transmission device to be open type, comparatively large by external action, operationally easily cause rain shaving electrical machine to burn as run into barrier obstruction; The supporting station of the scraping blade of the adhesive tape for wiper blade on market is all rigidity usually, because windshield is curve form, in addition manufacture the reason such as reason and use procedure wearing and tearing and cause windshield surface imperfection defect, scraping blade under non-yielding prop is difficult to adapt to the change on windshield surface, and only has a scraping blade, and in the process struck off, scrape cleanliness low, strike off efficiency difference, not easily quick scraping, easily causes blurred vision, brings potential safety hazard to driving.
Summary of the invention
Comparatively large in order to overcome noise when existing wiper driver train works, and, connect and catch up with transmission device to be open type, comparatively large by external action, operationally as run into the drawback that barrier obstruction easily causes rain shaving electrical machine to burn; The scraping blade of scraping blade under non-yielding prop of adhesive tape for wiper blade is difficult to the change adapting to windshield surface, water efficiency is scraped low in the process struck off, not easily quick scraping, the invention provides a kind of three scraping blade flexible wall supporting rain brush swing hydraulic pressure wipers, it is a kind of complete fully enclosed structure, noise is low, and not by external environment influence; Adhesive tape for wiper blade can be fitted with windshield better, and can scraping rapidly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three scraping blade flexible wall supporting rain brush swing hydraulic pressure wipers, comprise rain shaving electrical machine (36) and rain brush driver train (70) and rain brush (31), it is characterized in that: rain brush axle drive shaft (50) is divided into passive rain brush axle drive shaft (32) and active rain brush axle drive shaft (49), and coaxially connects with the passive oil cylinder gear wheel shaft (51) of ring gear tooth bar oscillating oil cylinder (34) and the actuating cylinder gear wheel shaft (52) of driving gear tooth bar oscillating oil cylinder (47) respectively;
Hydraulic oil pipe (48) UNICOM is passed through and transmitting torque between ring gear tooth bar oscillating oil cylinder (34) and driving gear tooth bar oscillating oil cylinder (47);
Driving gear tooth bar oscillating oil cylinder (47) is provided with a positive gear intermittent drive mechanism (53), its structure is: the actuating cylinder driven wheel (38) being provided with coaxial linkage in actuating cylinder gear wheel shaft (52) axial side, in the radial bilateral symmetry of actuating cylinder gear wheel shaft (52), two semi-circle gears are set, namely right semicircle gear (41) and left semicircle gear (42), alternately engage with actuating cylinder driven wheel (38) respectively;
Arrange in the axial side of right semicircle gear (41) and left semicircle gear (42) two respectively with right driven wheel (39) and the left driven wheel (40) of right semicircle gear (41) and left semicircle gear (42) coaxial linkage, between right driven wheel (39) and left driven wheel (40), be provided with a worm screw (46) be meshed with right driven wheel (39) and left driven wheel (40), one end of worm screw (46) connects with rain shaving electrical machine axle (45).Right driven wheel (39) can be driven to become counter motion with left driven wheel (40) when worm screw (46) is rotated, simultaneously, the right semicircle gear (41) of coaxial linkage also becomes counter motion with left semicircle gear (42), because right semicircle gear (41) and left semicircle gear (42) are alternately engage with actuating cylinder driven wheel (38), when right semicircle gear (41) engages with actuating cylinder driven wheel (38), actuating cylinder driven wheel (38) moves towards a direction, and when left semicircle gear (42) engages with actuating cylinder driven wheel (38), actuating cylinder driven wheel (38) moves in the opposite direction, thus drive rain brush to move back and forth.Hydraulic oil pipe (48) is flexible tube.
Described rain brush (31), adhesive tape for wiper blade fixed card slot (2) is provided with on the top of adhesive tape for wiper blade (1), bottom is provided with scraping blade (6), it is characterized in that: along symmetrical two tubular cavities that be arranged in parallel of the axis of adhesive tape for wiper blade (1) in the base plate (3) of described adhesive tape for wiper blade fixed card slot (2), left cavity (17) and right cavity (16), form left flexible wall (4) and right flexible wall (5) and median septum (12), base plate (3) and left cavity (17) and right cavity (16) form flexible wall supporting structure (7), be respectively equipped with in the lower end, both sides of base plate (3) and prolong the left scraping blade (10) and right scraping blade (11) and middle scraping blade (14) that flexible wall supporting structure (7) axially be arranged in parallel.Scraping blade can adapt to the curved surface change of windshield better under the supporting of flexible wall supporting structure, laminating makes to scrape cleanliness better increases, article two, tubular cavity is while guarantee flexible wall flexibility, possess again certain anti-excessive deformation and keep stable effect, and three scraper structures are three times that general single scraping blade strikes off efficiency.
The wall thickness of left flexible wall (4) and right flexible wall (5) is by thick gradual change shape thinning gradually from the upper and lower side of wall to centre.The middle part outwardly convex of left flexible wall (4) and right flexible wall (5).This design has again good stability while making flexible wall supporting structure have good flexibility.
The upper end of left scraping blade (10) and right scraping blade (11) and middle scraping blade (14) is respectively equipped with left scraping blade inverted trapezoidal supporting station (9) and right scraping blade inverted trapezoidal supporting station (8) and middle scraping blade inverted trapezoidal supporting station (15).The design of inverted trapezoidal supporting station prevents scraping blade from lodging, and rises and support and booster action, strengthens the toughness of scraping blade and have the effect preventing flexible wall supporting structure excessive deformation concurrently.
The invention has the beneficial effects as follows the rain brush driver train flexible duct hydrostatic drive of wiper, transmitting torque is large, volume is little, response rapidly, due to flexible duct hydrostatic drive, little by structural limitations during installation, and be enclosed construction completely, during work, noise is low, is especially applicable to external environment condition complex structure and long-distance transmission, can adapts to different automobile types, and not by external action, avoid the drawback because outer barrie thing causes rain shaving electrical machine to burn, significantly reduce internal car noise, improve the traveling comfort of inside during vehicle operating; Scraping blade rains better with the application of a surface degree of windshield in the supporting of flexible supporting structure, article two, tubular cavity is while guarantee flexible wall flexibility, possess again certain anti-excessive deformation and keep stable effect, three scraper structures are three times that general single scraping blade strikes off efficiency, thus improve rain shaving blade scrape cleanliness, Clear & Transparent gaze area can be provided to driver rapidly, provide sound assurance to safe driving.
