A double V-shaped 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 effects of large lateral stiffness, enhanced lateral force resistance, and increased lateral stiffness

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

Embodiment 1

[0029] Embodiment 1: as figure 1 Shown: a double V-shaped swing arm sliding type independent suspension, including a V-shaped lower swing arm 1, a lower linear guide rail 2, a first control slide bar 3, a second control slide bar 4, a V-shaped upper swing arm 5, and a second control slide bar. Three-control slider 6, fourth control slider 7, shock absorber 8, upper linear guide rail 9, hub bearing seat 10, V-shaped upper swing arm 5, third control slider 6, fourth control slider 7 and V The letter lower swing arm 1, the first control slide bar 3, and the second control slide bar 4 have the same structure and the same installation method, because the V-shaped upper swing arm 5, the third control slide bar 6, and the fourth control slide bar 7 only oppose the wheels The roll force can be reduced.

[0030] The lower linear guide rail 2 is a slide rail, which is horizontally fixed on the vehicle frame. One end of the V-shaped lower swing arm 1 is movably connected to the sliding ...

Embodiment 2

[0036] Such as figure 2Shown: a double V-shaped swing arm sliding type independent suspension, including a V-shaped lower swing arm 1, a lower linear guide rail 2, a first control slide bar 3, a second control slide bar 4, a V-shaped upper swing arm 5, and a second control slide bar. The three-control slide bar 6, the fourth control slide bar 7, the shock absorber 8, the upper linear guide rail 9, the hub bearing seat 10, and the lower linear guide rail 2 are horizontally fixed on the car beam. on the girder. One end of the V-shaped lower swing arm 1 is movably connected to the sliding end of the lower linear guide rail 2, the other end of the V-shaped lower swing arm 1 is movably connected to the hub bearing seat 10, and one end of the first control slider 3 and the second control slider 4 are respectively movably connected. At the midpoint of the V-shaped lower swing arm 1, the other ends of the first control slider 3 and the second control slider 4 are respectively movabl...

Abstract

The invention discloses a double V-shaped swing arm sliding independent suspension, a low linear guide rail is horizontally fixed on that main beam of the automobile, one end of the V-shaped lower swing arm is movably connected with the sliding end of the lower linear guide rail, the other end of the V-shape lower swing arm is movably connected with the hub bearing seat, one end of the first control slide bar and one end of the second control slide bar are respectively movably connected at a midpoint of the V-shaped lower swing arm, and the other ends of the first control slide bar and the second control slide bar are respectively movably connected to the outer frame of the vehicle body or the beam outer end, the connecting points with the V-shaped hem arm on the hub bearing housing are ina straight line parallel to the body, the upper linear guide is horizontally fixed on the car girder, one end of the damper is connected to the frame, and the other end of the damper is connected tothe hub bearing seat or connected to the wheel end of the V hem arm. The invention is suitable for any vehicle chassis, including passenger cars, freight cars, military vehicles, tanks, trains, low-speed trams, tricycles, old-age walking vehicles and the like.

Description

technical field [0001] The invention relates to an automobile chassis, in particular to a sliding type independent suspension with double V-shaped swing arms. Background technique [0002] The independent suspension of automobiles has been developed 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. Most cars now use independent suspension systems. According to their structure Different forms, the independent suspension system is mainly divided into McPherson independent suspension system, double wishbone independent suspension system, multi-link independent suspension system, dragging independent suspension system and so on. 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 height cannot be...
