Suspension structure and connecting mode of bridgeless automobile

Abstract

The invention provides a suspension structure and connecting mode of a bridgeless automobile and relates to the technical field of automobile running system structures. The invention discloses the suspension structure and connecting mode of the bridgeless automobile. The suspension structure and connecting mode of the bridgeless automobile comprises the steps of hinging and connecting the upper ends of left and right side suspensions of a frame to form a rotation point; hinging and connecting the lower ends of the left and right side suspensions with left and right side wheel supporting assemblies and one end of a transverse hydraulic supporting stabilizing bar to form rotation points; hinging and connecting the other end of the transverse hydraulic supporting stabilizing bar with a steering knuckle supporting seat assembly on a sub frame to form a rotation point; when the upper part of a vehicle body is inclined to one side under the influence of steering centrifugal force, the bottomof the sub frame can swing to one side reverse to the direction of the centrifugal force; during swinging, the tail end of a steering knuckle extrudes the transverse hydraulic supporting stabilizingbar to retract so that the transverse supporting distance of this side is shortened and the supporting position of this side is lowered; a hinging part on an associated side is enabled to rotate so that the gravity force of the vehicle body is naturally lowered to automatically offset the steering centrifugal force; and therefore, the supporting balance of the gravity centers, on the left and right sides, of the vehicle body is automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of a suspension structure of an automobile driving system, in particular to a suspension structure and a connection method of a bridgeless automobile. Background technique [0002] The stability and safety of automobile driving is the key technology in automobile design and manufacturing, which involves the safety of people's lives and property. my country is a populous country in the world. In recent years, with the continuous improvement of my country's economy and living standards, the number of automobiles has increased However, in the face of the situation that my country's automobile industry is large but not strong and future automobiles need to be energy-saving, environmentally friendly, safe and reliable, and the development trend of lightweight, intelligent and electrified automobiles, vehicle safety is one of the key technologies for competition in the automobile market 1. At present, due to the rap...

Problems solved by technology

[0010] In view of the above-mentioned lack of scientific structure of the driving system, the structure of the driving system lacks the control function of the steering centrifugal force and the function of self-adjusting the balance of the center of gravity support on both sides, so that the weight support of the wheels on both sides of the car body is unclear. At the same time, the two sides The side suspension system and the frame and wheels form a rectangular parallelepiped rigid connection through the front and rear axles or other components, so that the driving system cannot immediately realize the self-adjustment of the support balance of the center of gravity on both sides of the car body and tire wear when encountering changes in the road shape and the center of gravity of the car body. Faster problems, the biggest defect is that the wheels, suspension system, and the frame, axle or load-bearing body are horizontally connected to form a whole with lateral force, and the left and right wheel sides become the lever fulcrum for the lateral force of the car body. When the center of gravity of the car body deviates laterally from one side, the wheels and all elastic elements on one side are suppressed by gravity to lower their support, while the wheels and elastic elements on the other side are under the action of tire pressure and elastic force of the suspension elastic elements. If the support is rapidly increased, the lateral center of gravity of the upper part of the car body must be biased towards the weaker side of the support. With the further reduction of the road surface or the further deepening of the turning, as well as the simultaneous action of the steering centrifugal force and inertial force, the inclination of the upper part of the car body will increase, resulting in The wheel on one side with weak support is used as a support point to pry up the wheel on the other side through the left and right steel lateral force transmission, so that the grounding and direction control performance of the wheel on this side will deteriorate. The problem that the vehicle rolls over due to the failure of the direction
