Technical requirements for automotive glass lifter 1 Lifter shall comply with the requirements of this standard and shall be manufactured in accordance with the approved product drawings and design documents. The glass lifter shall be designed to be stable after installation, without abnormal sound, And stuck and other undesirable phenomena. That car glass lifter performance requirements which?
1, the movement parallelism movements to any position when the movement parallelism should not be greater than 0.3mm / 100mm (single arm should not be greater than 0.5mm / 100mm).
2, the glass descending lift up to any position, the withdrawal of the handle torque, the glass bottom edge of the decline should not be greater than 3mm.
3, static strength hoist movement to any position, the lifting device on the application of 400N load, the brake should be reliable, the parts should not be damaged and permanent deformation.
4, the operating strength of the elevator movement to any position, the fixed glass bracket, the drive shaft applied 14.7Nm torque, the various parts should not be damaged and permanent deformation, the transmission mechanism should not have teeth off phenomenon.
5, the durability of the lifting device in the reciprocating movements 2.O × 104 times (up and down a cycle of movement up and down a time) after the durability test should be consistent with 2.1 and 2.3.
6, the handle torque hoist maximum static handle torque should not be greater than 1.8Nm.
7, corrosion-resistant riser metal coating and chemical treatment layer should be consistent with the relevant provisions of QC / T625, corrosion resistance test, the lift should be consistent with 2.1.3.8 vibration-resistant automotive glass lifter to bear twice the actual car Glass gravity load, the vibration frequency of 33.3Hz, acceleration of 29.4m / s2 under the conditions of vibration up and down 4h, the connection should not fall off, loose, glass should not be greater than 5mm
