Overview of Passenger Car Transmission Bushings
Passenger car transmission bushings are crucial components specifically designed for vehicles such as sedans, SUVs, and MPVs. They reduce friction between parts within the transmission, ensuring smooth and efficient power transfer. Our passenger car transmission bushings use high-wear-resistant, self-lubricating materials, making them ideal for use in manual, automatic, continuously variable (CVT), and dual-clutch (DCT) transmissions.
Application Scenarios for Passenger Car Transmission Bushings
Highlight specific applications within different types of passenger car transmission systems:
- Manual Transmissions (MT): Bushings are used to support the shifting mechanism and synchronizer hubs, ensuring smooth and reliable shifting, suitable for small cars and sports sedans.
- Automatic Transmissions (AT): Bushings provide critical support and lubrication within the torque converter and planetary gear assemblies, suited for family cars and luxury vehicles in high-temperature environments.
- Continuously Variable Transmissions (CVT): Bushings reduce friction and noise in the pulley shaft and transmission mechanism, improving fuel efficiency, suitable for hybrid vehicles and compact SUVs.
- Dual-Clutch Transmissions (DCT): Bushings minimize friction in the dual-clutch system, enhancing shifting speed and smoothness, commonly used in high-performance cars and sports vehicles.
Applicable Vehicle Models
Our transmission bushings are suitable for various types of passenger cars, including but not limited to:
City Sedans: Focused on comfort and fuel efficiency, these models benefit from SF-1 or SF-2 light self-lubricating bushings, ensuring smooth shifting and quiet operation.
SUVs and Off-Road Vehicles: Designed to handle higher loads and complex road conditions, we recommend bimetallic or embedded graphite bushings for exceptional durability and reliability.
High-Performance Sports Cars: With a focus on speed and handling, these vehicles require greater stability and wear resistance, making embedded graphite bushings the optimal choice.
Materials & Technology of Gearbox Bushings
Our transmission bushings are made from various high-performance materials to meet the demands of different car models and challenging driving environments:
SF-1/DU Self-Lubricating Bushings: Made from a multi-layer composite material that includes a steel backing, a bronze powder layer, and a PTFE (Polytetrafluoroethylene) surface coating. These bushings perform exceptionally well in high-temperature and heavy-load conditions, reducing wear and noise while extending the transmission’s service life.
SF-2/DX Bushings: Also featuring self-lubricating properties, these bushings are designed to work well with external lubricants, making them ideal for semi-dry operation environments and higher load scenarios.
Bimetallic Bushings: Composed of a steel base combined with a copper alloy, these bushings offer excellent load capacity and outstanding wear resistance, making them well-suited for transmission systems that need to withstand higher loads, especially common in SUVs and off-road vehicles.
Embedded Graphite Bushings: These bushings have solid lubricants like graphite or MoS2 embedded in the copper alloy surface. They maintain low friction and self-lubricating characteristics under extreme conditions, making them ideal for sports car transmissions that require high stability at heavy loads or high speeds.
