3. Incoming Quality Control
To establish the AQL acceptable level of incoming material control, to provide the material for the whole inspection, sampling, immunity. On the acceptance of qualified products to warehousing, substandard goods to take return, check, rework, rework inspection; responsible for tracking bad, to monitor the supplier to take corrective
measures to prevent recurrence.
4. Process Quality Control
The manufacturing site of the first examination, inspection and final inspection, sampling according to the requirements of some projects, judging the quality change trend;
found abnormal phenomenon of manufacturing, and supervise the production department to improve, eliminate the abnormal phenomenon or state.
5. FQC(Final QC)
After the manufacturing department will complete the product, stand in the customer’s position on the finished product quality verification, in order to ensure the quality of
customer expectations and needs.
6. OQC(Outgoing QC)
After the product sample inspection to determine the qualified, allowing storage, but when the finished product from the warehouse before the formal delivery of the goods, there is a check, this is called the shipment inspection.Check content:In the warehouse storage and transfer status to confirm, while confirming the delivery of the
product is a product inspection to determine the qualified products.

Adjusting Gear Ratio in a Variable Gearbox
In a variable gearbox, adjusting the gear ratio is typically achieved through mechanisms like Continuously Variable Transmissions (CVTs). CVTs use various designs, such as pulleys with adjustable diameters or expanding/contracting belts, to vary the effective gear ratio continuously. By changing the effective diameters of the pulleys or the distance between the belt’s contact points, the gear ratio can be adjusted smoothly, allowing the engine to operate at its most efficient speed under different load conditions. Other variable transmission systems may use different principles, but the goal is to provide seamless and continuous adjustment of the gear ratio.
Contribution of a Variable Gearbox to Smoother Acceleration in Vehicles
A variable gearbox plays a significant role in achieving smoother acceleration in vehicles. Here’s how it contributes to this effect:
- Continuous Adjustment: Unlike traditional gearboxes with fixed gear ratios, a variable gearbox can continuously adjust its gear ratio to match the engine’s power and the vehicle’s speed. This ensures that the engine operates within its optimal power band, providing smoother and more responsive acceleration.
- Optimal Power Delivery: By selecting the most suitable gear ratio at any given moment, a variable gearbox ensures that the engine delivers the right amount of power to the wheels. This prevents sudden jolts or jerks during gear changes and maintains a seamless flow of power to the wheels.
- Stepless Transitions: Variable gearboxes, especially in the form of continuously variable transmissions (CVTs), offer stepless transitions between gear ratios. This means there are no distinct gear shifts, resulting in a smoother and more gradual increase in speed without the sensation of gear changes.
- Adapting to Load: A variable gearbox can adapt to changes in load, terrain, and driving conditions. It can select lower gear ratios for uphill climbs and higher ratios for cruising on flat roads, ensuring that the acceleration remains smooth regardless of the situation.
- Reduced Clutch Engagement: In manual transmissions, clutch engagement during gear shifts can sometimes cause jerky acceleration. With a variable gearbox, especially in automatic and CVT configurations, there is less reliance on clutch engagement, leading to smoother acceleration.
In summary, a variable gearbox’s ability to continuously adjust gear ratios, optimize power delivery, provide stepless transitions, and adapt to load conditions all contribute to achieving smoother acceleration in vehicles, enhancing both driver comfort and overall performance.
Benefits of Using a Variable Gearbox
A variable gearbox, such as a Continuously Variable Transmission (CVT), offers several advantages. It provides seamless and stepless transitions between gear ratios, resulting in smoother acceleration and improved fuel efficiency. Variable gearboxes adapt to changing driving conditions, maintaining the engine’s optimal power and torque output. They eliminate the need for conventional gear shifts, reducing driver fatigue and improving overall driving experience. Additionally, variable gearboxes can enhance engine responsiveness, reduce emissions, and provide better performance on inclines or variable terrains.
