Should the front axle rubber of the Sylphy be replaced with a rubber sleeve or the entire assembly?
1 Answers
The front axle rubber of the Sylphy needs to be replaced with the entire assembly because the front axle rubber sleeve and the front axle are integrated. The front axle is connected to the steering system via the steering knuckle, transmitting the steering force from the steering gear to the wheels to achieve vehicle steering. The components of the front axle are as follows: 1. Front axle: As the main component, the front axle is generally made of medium-carbon steel through die forging and heat treatment. Its cross-section is I-shaped or, to improve torsional strength, has a thickened section near each end shaped like a fist, with a through-hole where the kingpin is inserted. The middle part is bent downward into a concave shape to lower the engine position, thereby reducing the vehicle's center of gravity. 2. Steering knuckle: This is the hinge for wheel steering, shaped like a fork. The upper and lower forks have coaxial holes for installing the kingpin, and the steering knuckle spindle is used to mount the wheel. The ears on the steering knuckle's pin holes are connected to the fist-shaped parts at both ends of the front axle via the kingpin, allowing the front wheels to pivot around the kingpin for steering. 3. Kingpin: This connects the front axle and the steering knuckle, enabling the steering knuckle to swing around the kingpin for wheel steering. The middle of the kingpin has a groove; during installation, the kingpin fixing bolt aligns with this groove to secure the kingpin in the fist-shaped hole of the front axle. 4. Wheel hub: The wheel hub is supported on the spindle at the outer end of the steering knuckle via two tapered roller bearings. The bearing tightness can be adjusted with an adjustment nut (located at the outer end of the bearing). The outer end of the hub is covered with a pressed metal cap, and the inner end is equipped with an oil seal. The brake backing plate and dust cover are both fixed to the steering knuckle.
