A double swing arm sliding independent suspension

An independent suspension and sliding technology, applied in the direction of suspension, elastic suspension, transportation and packaging, etc., can solve the problems of unsatisfactory variation of wheel camber angle, inability to greatly reduce the height of the chassis, and inability to take into account excellent performance at the same time, etc. , to achieve the effect of large lateral stiffness, simple structure, and less space occupation

Problems solved by technology

MacPherson's independent suspension system is satisfactory in terms of driving comfort, but its structure is straight, which lacks resistance to impacts in the left and right directions, and the chassis height cannot be greatly raised and lower, and the change of wheel camber is not regular. ideal
Other independent suspension systems also have defects to varying degrees in terms of roll, large lifting of the chassis, changes in wheel camber, "nodding" when starting and braking, high center of gravity, excessive turning speed and easy rollover, etc., and cannot take into account its excellent performance at the same time
Non-independent suspension comfort, poor ride comfort, heavy trucks and easy to cause road damage

Abstract

The invention discloses a double swing arm sliding independent suspension, A low linear guide rail is horizontally fixed on that main beam of the automobile, A low swing arm end is movably connecte with a sliding end of a lower linear guide rail, the other end of the lower swing arm is movably connected to the hub bearing housing, first sliding lever, one end of the second sliding lever is movablyconnected at the middle point of the lower swing arm, The other end of the first sliding control rod and the second sliding control rod are movably connected to the outer frame of the vehicle body orthe outer end of the cross member respectively, are in a straight line with the connection point of the lower swing arm at the hub bearing seat and parallel to the vehicle body, and one end of the shock absorber is connected to the vehicle frame and the other end is connected to the hub bearing seat or is connected to the wheel end of the lower swing arm. The first sliding control rod and the second sliding control rod are respectively movably connected to the outer frame of the vehicle body or the outer end of the cross member. Whether on various roads, in various states such as low, high speed, turning and the like, the camber angle of the wheel does not change, the wheel always moves perpendicularly to the vehicle body, the left and right parameters before and after the wheel track arealways kept unchanged, the wear of the tire is greatly reduced, the lifting and lowering range of the wheel is wide, the length distance of the lower swing arm can be reached, and the off-road performance is improved.

Description

technical field [0001] The invention relates to an automobile chassis, in particular to a sliding type independent suspension with double swing arms. Background technique [0002] Development of Automobile Independent Suspension For more than 80 years, the driving stability, comfort, safety, ride comfort and off-road performance of automobiles are closely related to the suspension system in the chassis structure. [0003] Most cars now use independent suspension systems. According to their different structural forms, independent suspension systems are mainly divided into McPherson independent suspension systems, double-wishbone independent suspension systems, multi-link independent suspension systems, and drag-and-drop suspension systems. independent suspension system, etc. McPherson's independent suspension system is satisfactory in terms of driving comfort, but its structure is straight, which lacks resistance to impacts in the left and right directions, and the chassis h...
