Cause Analysis:

Due to a defective design, the two-stage return spring is unable to tolerate high tensile stress and may easily break, the flap can not return to the original position. Consequently, the throttle valve will experience premature failure.

Return spring structure - New Technology:

vika: Change the two-stage structure.

Imported 304 stainless steel.

The spring has passed 7.5 million fatigue tests and has high fatigue resistance.

OE: The two-section structure cannot withstand the torsional strength of long-term work.

Steering angle sensor - New Technology:

vika:The anti-interference ability is enhanced, which can effectively prevent the damage to the chip caused by static electricity. 360-degree signal reception, more accurate and more sensitive.

OE:Hall mechanical structure brush plate, long-term contact during equipment operation will lead to sensor failure.

Flap - New Process:

vika:The flaps are anodized to reduce grease adhesion during equipment operation.

OE:Normal aluminum,without surface treatment, the products may easily absorb oil and dirt particles and consequently lead to jamming.

Gear - New Material Added:

vika:PA66 +GF30+ PTFE15% . The friction coefficient of gears containing Teflon material is reduced. Gears work more smoothly

OE:PA66 +GF30, material wears easily.
