the purposes of vika knuckle：
Steering drive shaft is used widely on vehicles. On models with a front engine and rear drive or all-wheel-drive layout, due to deformation of the spring suspension, the position of the transmission or power divider output shaft relative to the driving axle input shaft often changes. That’s why a universal joint steering drive shaft is usually used. If the angle between inner and outer half shafts of the steering drive axle varies depending on drive conditions, a constant-speed steering drive shaft is typically adopted. In cases where the rear drive axle serves as an independent suspension, a steering drive shaft must be used as well.
Depending on whether significant flexibility is present in the knuckle turning direction, the knuckle can be divided into two types: rigid and flexible. A rigid knuckle transmits power via the hinge connection of parts. It may take three different forms: variable-speed knuckle (e.g., universal joint type), semi-constant-speed knuckle (e.g., duplex, protruded, and three-pin axle type), and constant-speed knuckle (e.g., ball yoke type and ball cage type). A flexible knuckle transmits power via flexible parts, and plays a cushioning role.
During operation of a variable-speed knuckle, when the angle between the two axes connected to the knuckle is larger than zero, the movement is transmitted with a changing instantaneous angular speed ratio between the output shaft and the input shaft, with an average angular speed ratio of 1. During operation of a semi-constant-speed knuckle, the movement is transmitted with an instantaneous angular speed ratio equal to 1 at a designed angle, and close to 1 at other angles. A knuckle that transmits movement with an instantaneous angular speed ratio between the output shaft and the input shaft of1 permanently is called constant-speed knuckle.
