The main lubrication problems of the door stopper:

※, continuous noise reduction, noise occurs after the door stopper works for a period of time;

※ Strict long-life lubrication requirements, the grease of the door stopper evaporates too quickly, it will dry out after a period of time, and the lubrication is insufficient, resulting in stagnation, large resistance, and unclear gear positions;

※, It is incompatible with plastic, and the rubber block or plastic expands and contracts;

※, strict environmental protection requirements, many oils and fats have not passed the relevant environmental certification;

Solution:

※ For noise problems, choose a grease with a suitable consistency and a slightly higher viscosity to improve noise reduction performance;

※ As the lubricating grease will dry out after a period of time, it is necessary to select the lubricating grease made of advanced precision base oil and precise process;

※, using grease with good plastic compatibility;

※, To meet the requirements of the current market, all automotive products must meet environmental requirements. ...

Simulation bench experiment:

basic introduction:

★This bench simulates the working state of the car door stopper, and can carry out the durability test of the slider type and ball type door stopper.

★Durability test can be performed on the door limiters of four doors at the same time, and through the endurance test to find suitable grease to extend the life of the door limiters.
