Automotive steering gears can be classified into: rack and pinion type, worm and roller type, and recirculating ball type. The rack and pinion steering gear is a common type, whose basic structure consists of a pair of meshing pinion and rack. When the steering shaft drives the pinion to rotate, the rack moves linearly. The worm and roller type steering gear uses the worm as the driving component and the roller as the driven component, typically employed in trucks requiring greater steering force. The recirculating ball type steering gear mainly consists of two parts: the mechanical part and the hydraulic part. The mechanical part includes the housing, side cover, upper cover, lower cover, recirculating ball screw, rack nut, rotary valve spool, and sector gear shaft.

What is the engine oil specification for Nissan Sylphy?

Nissan Sylphy uses 0W30 or 5W30 engine oil. Engine oil is known as the blood within the engine, playing roles in lubrication, cleaning, sealing, and heat dissipation. When the engine is running, the oil forms a film on the surfaces of various components inside the engine, thereby reducing friction and heat generation. The Sylphy is a model under Dongfeng Nissan Passenger Vehicle Company, with body dimensions of 4641mm in length, 1815mm in width, and 1447mm in height, and a wheelbase of 2712mm.

How to deal with peeling car clear coat?

Steps to repair peeling car paint: 1. Clean the car paint surface and ensure it is completely dry; 2. Remove the peeling part of the paint; 3. Simply repaint using the required painting method and materials. After the car has just been painted, it is best not to wash it for at least 24 hours, preferably 48 hours, because the newly applied paint has not fully adhered during this time. Washing the car within this period can definitely damage the clear coat on the paint surface, thereby reducing the paint's adhesion. Peeling car paint is caused by an improper ratio of clear coat to hardener during the painting process, which prevents the clear coat from adhering well.
