Passenger cars—Windshield wipers—Wiped areas1 Subject content and applicable scope
This standard specifies windshield wipers Requirements and measurement methods for wiper area wiped by glass wipers. This standard applies to cars, and passenger cars with no more than 9 seats may also be implemented by reference. 2 Reference standards
GB11562 Car driver’s front view
GB11556 Performance requirements for car windshield defroster device 3 Terms
3.1 Windshield wiper
GB11565- 89 | 3.2 Wiper blade
The wiper blade refers to a component that is equipped with a rubber strip in the wiper and can transmit the pressure of the wiper rod to the windshield through the rubber strip through the bracket and control mechanism ( Hereinafter referred to as scraper). 3.3 Wiping area
The wiping area refers to the area that the wiper blade can scrape within a specific range of the outer surface of the windshield glass. 3.4 Actual scraping area
The actual scraping area refers to the area scraped on the outer surface of the windshield when the wiper blade operates at the highest frequency. 3.5 Design scraping area
Design scraping area refers to the scraping area obtained by theoretical calculation. 3.6 Increased brushing area
Increased brushing area refers to the part of the wiper blade that exceeds the designed wiping area due to the inertia of movement of each part of the wiper in actual operation. 3.7 Working cycle
The working cycle refers to the process in which the wiper blade moves from the extreme position at one end to the extreme position at the other end and returns to the original position when the wiper is working.
3.8 Transparent area
See Articles 3.5 and 4.1 in GB11562.
4 Technical requirements
4.1 Each vehicle must be equipped with electric wipers that can be started or stopped by simply operating a switch. 4.2 The wiper wiper area shall not be less than 98% of area A and 80% of area B. The State Bureau of Technical Supervision approved the implementation on 1989-08-10 on 1990-03-01
GB11565-89www.bzxz.net
5A and B areas are determined according to the relevant provisions in Chapter 5 of GB11556. 4.3
5 Measurement methods
5.1 Main instruments and equipment
8. Plotter that meets the design area of ??windshield and wiper; b. Large transparent plastic plate;||tt ||c. Test bench
d. Other tools and materials. Such as: colored pens, water spray devices, medical talcum powder, etc. 5.2 Drawing measurement method
5.2.1 Draw the design wiping area and additional brushing area on the outer surface of the windshield (the additional brushing area can be set by testing or based on experience). 5.2.2 Draw the outer surface of the windshield glass, the transparent area and the AB area on the outer surface of the windshield glass in the top view and side view of the vehicle. 5.2.3 Draw the expansion diagram of the outer surface of the windshield glass and the transparent area, and draw the expansion diagrams of the designed wiper area, additional brushing area, and area A and B according to the corresponding relationship into the expansion diagram of the outer surface of the windshield glass and the transparent area. Pictured. 5.2.4 Calculate the percentage of the design scraping area and the additional brushing area in areas A and B according to the above synthetic expansion diagram. This percentage shall comply with the provisions of Article 4.2.
5.3 Bench measurement method
5.3.1 The voltage of the test power supply should be lower than 12V or 24V. 5.3.2 Start the wiper installed on the stand. At the same time, the water spray device sprays water evenly onto the outer surface of the windshield with a water volume of 820cm/min. The wipers work at the highest frequency and the actual wiped area is marked. 5.3.3 Draw the design scraping area and the expanded drawings of areas A and B required in 5.2.3 on the same large transparent plastic board. 5.3.4 Expand the actual scraping area measured on the bench and plot it on the large plastic plate mentioned in 5.3.3. Then calculate the percentage of the actual scraping area in areas A and B. This percentage shall comply with the provisions of Article 4.2. 5.4 Real vehicle measurement method
5.4.1 The scraping area of ??the actual vehicle should be measured in a temperature environment of 10 to 40°C. 5.4.2 The engine should operate at 30% of the maximum power speed. At the same time, the near light source and heater (or air-conditioning system) should be turned on, and the ventilation system should also work at maximum load.
5.4.3 According to the provisions of Article 4.3, determine areas A and B on the outer surface of the windshield. 5.4.4 Use methanol, alcohol or other equivalent detergents to thoroughly clean the oil stains and contaminants on the outer surface of the windshield glass. After drying, clean it with 3% to 10% ammonia water. After drying, wipe it with a soft cotton cloth. The entire outer surface of the windshield. Under the condition that the wind cannot blow directly, spray a thin layer of dry medical talcum powder evenly on the outer surface of the windshield glass. 5.4.5 Start the wiper and make the wiper wipe at the highest frequency for 5 to 10 working cycles, and then turn off the wiper. Draw an outline of the actual wiper area on the outer surface of the windshield. Remove talcum powder from this surface. 5.4.6 Calculate the percentage of the actual scraping area in areas A and B. This percentage shall comply with the provisions of Article 4.2. Additional notes:
