However, the suspension system used for super-heavy chassis has large load, large wheel jump stroke, complex working conditions, and limited layout space, which puts forward higher requirements for the optimization and engineering design of the suspension system guiding mechanism
[0003] At present, there are still relatively few introductions to the engineering design methods and design points of the guiding mechanism of the super-heavy-duty chassis suspension system with an axle load greater than 13t, especially for the guiding mechanism of the suspension system with a wheel jump stroke greater than 200mm, which lacks design specifications and references

Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0030] The super-heavy chassis adopts double wishbone independent suspension, and the guiding mechanism of the suspension system includes upper wishbone assembly and lower wishbone assembly. The upper cross arm assembly is composed of upper cross arm, metal bearing, oil seal, metal gasket and pin, and the lower cross arm assembly is composed of lower cross arm, metal bearing, oil seal, metal gasket and pin. The inner sides of the upper and lower cross arms are connected to the frame through pin shafts, and the cross arms can swing around the pin shafts in the YZ (vehicle coordinate system) plane; degrees of freedom to swing left and right. By optimizing the hard point of the guiding mechanism, the changes of the wheel alignment parameters and the height of the roll center when the wheel jumps up and down are kept as small as possible, ensuring that the ...

An independent suspension guide mechanism for a super-heavy-duty chassis, including an upper cross arm assembly and a lower cross arm assembly. Internal swing; the outer sides of the upper and lower cross-arm assemblies are respectively connected to the upper and lower interfaces of the steering knuckles of the wheel set through ball joints, and the ball joints provide the degree of freedom for the wheels to jump up and down and swing left and right; the lower cross-arm assembly meets the structural requirements. On the premise of strength, open a gap as deep as possible on the inner side and outward; the YZ plane is a coordinate plane defined in the vehicle coordinate system.
Description
technical field [0001] The invention belongs to special vehicle chassis technology. Background technique [0002] Domestic and foreign studies on the influence of suspension guide mechanism on handling stability have been relatively rich, and many valuable explorations have been made on the optimization design of suspension system guide mechanism, which provides a rich reference for related research. However, the suspension system used for super-heavy chassis has large load, large wheel jump stroke, complex operating conditions, and limited layout space, which puts forward higher requirements for the optimization and engineering design of the suspension system guiding mechanism. [0003] At present, there are still relatively few introductions to the engineering design methods and design points of the guiding mechanism of the super-heavy-duty chassis suspension system with an axle load greater than 13t, especially for the guiding mechanism of the suspension system with a whe...
