Embodiment Construction

[0014] Figure 1-Figure 6 In an embodiment, a hydraulic swing wiper drive mechanism includes a wiper motor (36) and a wiper drive shaft (50). The feature is that the wiper drive shaft (50) is divided into a passive wiper drive shaft (32) and an active wiper drive shaft. The shaft (49) is coaxially connected with the driven cylinder gear shaft (51) of the driven rack and pinion swing cylinder (34) and the driving cylinder gear shaft (52) of the driving rack and pinion swing cylinder (47) respectively; the driven gear The rack swing cylinder (34) and the driving gear rack swing cylinder (47) communicate with each other through a hydraulic oil pipe (48) and transmit torque; the driving gear rack swing cylinder (47) is provided with a positive and counter gear intermittent transmission mechanism (53), the structure is: on the axial side of the drive cylinder gear shaft (52), a coaxially linked drive cylinder drive gear (38) is provided, and two symmetrically arranged on both sides ...

Abstract

The invention discloses a windshield wiper drive mechanism based on hydraulic swing. The windshield wiper drive mechanism based on hydraulic swing comprises a windshield wiper motor and a windshield wiper drive shaft and is characterized in that two gear rack swing oil cylinders are communicated and transmit torque through a hydraulic oil pipe, and the driving gear rack swing oil cylinder is provided with a positive and reverse rotation gear intermittent transmission mechanism. The windshield wiper drive mechanism based on hydraulic swing has the advantages that flexible duct hydraulic transmission is adopted in the windshield wiper driver mechanism of a windshield wiper, so the windshield wiper driver mechanism is large in transmission torque, small in size and quick in response; due to the flexible duct hydraulic transmission, the limitation for the windshield wiper driver mechanism during installation is small; in addition, due to a completely sealed structure, the windshield wiper driver mechanism is low in noise during working, and is especially suitable for external environments with complicated structures and long-distance transmission; the windshield wiper driver mechanism is not affected by the outside, overcomes the defects that the windshield wiper motor is burnt out due to external obstacles, effectively reduces in-car noise and improves inside comfort of a vehicle during operation.

Description

Technical field [0001] The invention relates to a wiper drive mechanism, which belongs to the field of automobile wipers, in particular to a wiper drive mechanism of a flexible pipe hydraulic transmission. Background technique [0002] At present, the wiper drive mechanism of wiper blades on the market is mostly continuous transmission, and the noise during operation is relatively large. Moreover, the continuous transmission mechanism is open type, which is greatly affected by external influences. It is easy to block when obstacles are encountered during work. Causes the wiper motor to burn out. Summary of the invention [0003] In order to overcome the disadvantages that the existing wiper drive mechanism is noisy when it works, and the continuous drive mechanism is open, which is greatly affected by external influences, and if obstacles are encountered during operation, the wiper motor will burn out, the present invention provides A hydraulic swing wiper drive mechanism, which ...
