1、附录Hyundai Motor on the steering control of the request is lightweight, safe, reliable, and should have sufficient life. In order to meet these requirements, the design of the steering gear should have a reasonable transmission ratio characteristics, the correct gap eating together, a higher transmission efficiency, sufficient rigidity and strength. If the steering gear in the design is reasonable, then the product is good and bad parts of the key issues of manufacturing and assembly. How to cont

2、rol the quality of the product? The key problem is that a reasonable detection methods, the key to strictly control the passing rate of time, such products will be able to guarantee the quality of parts and components. First of all, the quality of shifting ASSY, should control the assembly and to ensure that turning the steering shaft torque and rotational axis and the transmission gap between components. Followed by testing the performance of steering gear, steering gear must also be adopted by

3、 all types of test-bed to verify the established angle transmission ratio, transmission efficiency, rotational torque, rigid. In addition to examination other than the above-mentioned steering performance, but also in the pilot stage of its life nuclear reliability and life expectancy that is static torsion test: a thin red hammer, hit test, fatigue life test. To determine whether the quality of the product in hand national standards. Noise from the steering angle repair cream, which is also a t

4、est method to detect and can learn from the J class machinery manufacturing industry in Chinain the past only means to recognize the importance of detection, and the lack oflack of testing and testing of the poor law awareness. So have some of the parts is a qualified products l materials, and assembly of products from the pilot test proved to be defective, or: The test can verify the quality of products and design for the steering gear (1) the accuracy of parts of the foot only, finish second,

5、two-phase - the location of the elite Measuring the content of L steering shaft loaded journal bearings Department feet inch accuracy and smoothness, anti-worm or worm-inch accuracy, smoothness and surface hardness and magnetic for testing; steering vertical axis arm journal dimensional accuracy and smoothness, the worm wheel roller bearing of the journal center hole distance, wheel bearing and the journalhole angle from the Chinese side, the block size, finish and degree of asymmetry; circulati

6、ng ball tooth-type radial fan, big-law length, journal hardness, the magnetic; browser to Min Xuan cochlear aperture wheel size precision, smoothness, tooth surface roughness, intermediate thick teeth, tooth, tooth degree of asymmetry; ball rolling circle diameter, smooth, cylindrical roller Roaddegree of accuracy and bias, raceway adjacent pitch error, cumulative error section of grass lines and sub-rack section from Rolling Road Center, rack section Road center line and the roll of injustice:

7、line degrees; carburizing layer thickness, hardness; magnetic flaw detection; shift steering shaft shell aperture, roughness, different degree of heart; shift towards vertical axis aperture arm flying finish, different degree of heart; chaos and steering shaft steering arm hole down the center distance, steering shaft-hole axes and steering arm hole down the center line of the non-verticality (2) parts of cleanliness. Detection of the site is turning - browser shell surface and the surface parts

8、. Detection method is to use cleaning fluid to clean parts, and then the cleaning fluid with impurities, and vacuum membrane leaching; further 120 weeks of petrol industrial solvents the membrane will be washed with impurities. To be volatile after the membrane cleaning fluid, together with the impurities from weighing, with the magnet cellophane packets are sorted in the iron impurities, said the weight of a scrap-iron. The iron filings and then 40 times on the microscope with a disability in m

9、ost dogs measured particle size (length X width). (3) assembly of the leakage. Does not allow any leakage of the phenomenon of steering. Because of internal lubricants in the steering gear is used to turn parts lubricated friction pair, and if as a result of damage caused by leaking seals, lubrication will be affected, resulting in increased friction and wear parts and reduce the life span of steering gear; transmission efficiency at the same time will lower. The use of conventional vibration and temperature +40 C under the conditions of inspection, the shell and shell cap shaft oil seal joints as well as whether the spill, and water to observe whether there are leakages. (4) after a good tune steering assembly should check the technical requirements flexible and comfortable when turning the steering wheel, there is no axial gap I turn the steering wheel of the total value of the number required to turn around a few cars in line with
