AI Technical Summary
Technical Problem
The assembly of traditional subframe bushings is complex, and the small bolt connection area leads to insufficient connection strength, affecting the safety and reliability of the vehicle.
Method used
A first washer and a second washer are added to both ends of the inner core and fixed to the inner core by a press-fit connection. They are combined with rubber parts and outer shell to form an embedded connection, which increases the contact area of the bolt connection and improves the reliability and stability of the connection.
Benefits of technology
It simplifies the assembly process, improves connection strength and stability, prevents bolts from loosening, enhances vehicle safety and reliability, and reduces production costs and time.
