Product overview
1. The stepless limiter is a product that combines reliability, operating comfort, and ease of use.
2. This product is mainly used in Mercedes-Benz G500, Tank 500 and other models with swing doors, so that the back door can hover at any position during the opening process, and can be locked when it is opened to the maximum angle.
Product Features
1. When the external force of the swing door equipped with the stepless limiter is less than the set value of the internal balance valve, the door remains stationary. When the external force is greater than the set value, the balance valve opens, and the swing door can be opened and closed freely. Keep the limit when the external force disappears.
2. When the swing door equipped with the stepless stopper is opened to the maximum angle, the outer two plastic sleeves can be rotated in the opposite direction. At this time, the stepless stopper is locked, and the swing door can resist factors such as strong wind. Maintain limit.
Product advantages
1. The piston rod penetrating design is adopted, which can withstand up to 8000N axial drawing force without disconnecting.
2. The internal structure is optimized, which reduces the cumulative error of the product and increases the reliability of the product compared to the 40% reduction of internal parts.
3. The internal seal structure is optimized, and the number of seals is reduced at the same time, so that the durability life is significantly increased and the failure rate is significantly reduced.
4. Independent research and development, has obtained the invention patent authorization, patent number: ZL 202210365062.7 stepless limiter and its processing equipment
