TECHNICAL FIELD

[0001] The utility model relates to heavy truck parts technical field especially relates to a right heavy truck narrow body car model steering gear support. BACKGROUND

[0002] The steering gear support is a key component in the automobile steering system, and its main function is to fix and support the steering gear to ensure its stable work. As a key component of the automobile steering system, the stability of the steering gear support directly affects the performance and safety of the steering system and plays an important role in the automobile steering system. In order to ensure the safety and stability of the automobile, it is necessary to select a suitable steering gear support and regularly maintain it.

[0003] The steering gear support is one of the important components of the automobile steering system, and the layout form adopted by domestic heavy trucks is basically left steering gear support, while western countries mostly adopt right steering gear support. Heavy truck, short for heavy truck, is a general term for heavy trucks and semi-trailer tractors, and occupies an important position in the global range. At present, the right steering gear support used by heavy trucks mainly adopts the arrangement mode of frame plus front suspension casting plus steering gear support plus steering gear.
