See sideshaft.
A torque-sensing limited slip differential where gear separation forces between the parallel axis helical gears react in axial and radial direction. The resultant axial and radial force vectors generate friction between the pinions and the differential case; between the side gears and the differential case, as well as between the pinion gear and the side gear tooth surface. The resulting torque bias resists differentiation.
The high-speed AC (HSAC) joint is a six-ball Rzeppa style angular contact fixed ball joint. It can be used to replace a cardan joint in operating angles up to 15°, without the noise issues of non-CV cardan joints. The HSAC operates well in all vehicle types.
High speed tripod joints are used where installed angles are low, but axial (plunging) motion is needed. This type of joint is often used in all-wheel drive vehicles to prevent engine movements or vibrations from being transmitted into the passenger compartment. The high speed GI (HSGI) joint requires a very low dynamic plunge force and can be used in operating angles up to 2°.
High speed joints are constant velocity joints that are capable of rotating at high speeds, for example over 6000 revolutions per minute. This enables them to be used for propshafts, which are required to turn at higher speeds than sideshafts. The higher speed requirements require specific design features not included in their sideshaft equivalants.
The high speed PC crosstrack TM is a high speed plunging joint that combines features from the DO and VL joints, giving it excellent performance in dynamic plunge and backlash. It is especially suited to hang-on all wheel drive systems with transverse engines. It can be used in operating angles up to 7.5°.
The high speed VL-LP (HSVL-LP) is a longer plunge version of the HSVL joint. It operates in angles up to 7° with a 50mm plunge.
The High Speed PDO joint is a plunging ball joint with similar benefits to the tripod joint, and is used in similar applications. The PDO joint also exhibits low rotational lash, which helps improve driveline NVH (noise, vibration, harshness) characteristics. It can be used in operating angles up to 3°.
The high speed PX countertrack TM joint is the next generation of the AC joint. The PX is an opposed track 4+4 design fixed ball joint. It is highly efficient compared to all other joint types and allows operating angles up to 15°.
The high speed PXS joint is an opposed track 5+5 design fixed ball joint. The PXS has an extremely narrow package. It can be used in operating angles up to 3° and due to the opposed track design it has very high efficiency.
The High Speed VL (HSVL) joint is capable of running at high installed angles, and its plunging properties allow for dynamic driveline motion or variations in vehicle build tolerance. HSVL joints are capable of plunging up to 22mm, running at high installed angles, and high rotational speeds.
