In the heavy-duty truck industry, reliable drivetrain and separation system performance is critical to ensure vehicle safety, operating efficiency, and long service life. For Shaanxi Heavy Duty Automobile, MTWB successfully developed a customized truck separation bearing in 2023 to address the demanding requirement of high-load operation, frequent engagement cycle, and harsh working environment. By optimizing bearing structure, material selection, and manufacturing precision, MTWB truck separation bearings provide stable performance, reduced maintenance requirement, and a cost-effective alternative to international brand bearing solution for heavy-duty commercial vehicle.
01 Introduction to Separable Bearings
02 Introduction of Product Design Feature
03 R&D improvement process
04 Test Report
The separable bearing is the core component of the clutch system in heavy-duty truck.
Compact structure, suitable for clutch system with limited space, suitable for heavy-duty truck.
Bearing body: high-precision spherical bearing, ensuring low friction and high-speed operation.
Sealed structure: dustproof, waterproof, and oil leakage resistant design, extending service life.
Adopting double-layer sealing, the sealing plate uses F rubber,and the grease is selected from Krupp high-temperature grease to enhance high temperature resistance and wear resistance.
The opposite component here is formed by grinding and processing.
Advantages: High precision, small size tolerance range.
Use Krupp B L P 7 2-1 2 bearing grease instead. High performance synthetic grease designed for
heavy-duty, high-temperature, and high-speed rolling bearing.
The existing sealing mechanism for the clutch release bearing of heavy-duty truck is a single-layer structure with average sealing performance. After a period of use, the lubricating oil will leak, affecting
its use. Our company offers a dual sealing structure that greatly improves sealing performance and has obtained patent certification.
Before improvement, use a single-layer iron sealing ring.
After improvement, double-sided double sealing ring are used, and an additional layer of F rubber sheet sealing ring is added on top of the iron sealing ring.
Advantage: The dustproof, waterproof, and oil leakage prevention level have been increased, mainly reducing oil leakage.
Customer Requirement:
1. Cover assembly speed: 1500 r/min
2. Separation stroke: 12mm
3. Frequency: 1Hz~2Hz
4. Test temperature: 150 ± 5 ℃
5. Standard block thickness: 10 ± 0.02mm
6. Test frequency: 2 million times.
7. Matching cover assembly: The maximum separation force of the FD430L-1601100GR-03 cover assembly is 7854.6N.
After 2 million bench simulation life tests at 150 ℃ (The maximum temperature of the bearing is
148℃), the bearing rotational resistance increased and the bearing did not leak oil, so it can
still be used.
