Description
Technical field
The utility model relates to Automobile manufacturing, particularly a kind of automobile independent suspension system.
Background technology
Automobile independent suspension develops over more than 80 year, the riding stability of automobile, traveling comfort, safety, ride comfort and cross-country traveling ability, all closely bound up with the suspension in chassis structure, present car mostly adopts independent suspension system, different according to its version, independent suspension system is mainly divided into: Mai Fuxunshi independent suspension system, two fork arm type equal independent suspension system, multi link independent suspension system, towed independent suspension system etc., the performance of Mai Fuxunshi independent suspension system in road-ability is still satisfactory, but it is configured to straight barrel type, barrier force is lacked to the impact of left and right directions, significantly can not be elevated chassis height, and camber angle Changing Pattern is undesirable.Also to rolling, being significantly elevated chassis, camber angle change etc., all there is defect in various degree, its premium properties can not be taken into account simultaneously in other independent suspension system.
Utility model content
The purpose of this utility model is: in order to solve prior art problem, provides that a kind of camber angle is unchanged, analysis of wheel vertical is beated in vehicle body, the swing arm sliding-type independent suspension device that lifting moving wide ranges, anti-side are inclined, anti-swing strength is strong.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of swing arm sliding-type independent suspension device, comprise lower swing arm, horizontal slip device, front brace, rear brace, horizontal slip device is fixed on automotive frame, lower swing arm one end is movably connected in horizontal slip device, lower swing arm can slide in horizontal slip device, the other end of lower swing arm is movably connected on automotive wheel, front brace, one end of rear brace is movably connected on 1/3-1/2 place of lower swing arm from horizontal slip device, front brace, the other end of rear brace is movably connected on the inner side of vehicle body outer rim respectively, with horizontal slip device in same level.
Described horizontal slip device is horizontal concrete chute.
Described horizontal slip device can independent design be fixed on automotive frame, also can directly design on automotive frame.
Described flexible connection is that pivot pin connects.
Described front brace, rear brace can be designed to linear or arc.
One end of described front brace is movably connected on 1/3-1/2 place of lower swing arm from horizontal slip device, and rear brace is fixedly connected on front brace.
The length of described lower swing arm is more than or equal to the distance length of the required movement of wheel.
The front brace of the utility model, rear brace are designed to linear, are practically applicable to rear-mounted; Front brace, rear brace are designed to arc, or do not affect other shapes of wheel steering, are practically applicable to forward mounting.The length of lower swing arm, front brace, rear brace, connection location, shape can make the appropriate adjustments with the requirement of different automobile.
The utility model swing arm sliding-type independent suspension can be designed to wish-bone arm type suspension or trailing arm type hangs or utilization or double wish-bone arm type suspension etc. simultaneously.
The front brace of the utility model, rear brace can at the both sides of lower swing arm or homonymies, and front brace, rear brace, lower swing arm form firmly triangular structure, and the effect of front brace, rear brace allows lower swing arm move up and down, and prevents lower swing arm swing.
Its lower swing arm road wheel end of the utility model extends on wheel center of effort line as far as possible, and to reduce the lateral pressure of wheel to stub, the side force that wheel is subject to reaches front and back brace mainly through lower swing arm and directly passes in vehicle body, so its lateral stiffness is large, anti-roll force is strong.
The utility model utilizes two pendulum effect to cancel out each other straight principle, or say that utilizing circular arc to draw straight line principle designs, deviation is 0 in theory, described horizontal slip device only allows lower swing arm horizontal slip, the pendulum effect that lower swing arm road wheel end produces when doing perpendicular movement is connected the pendulum effect counteracting that the front and back brace on lower swing arm produces, define wheel absolute upright in the theory of vehicle body straight-line motion and effect, present general manufacturing technology precision controlling between 0.01 one 0.03mm, vehicle for prior art is about the swing deviation of 20mm, improve up to ten thousand times, and amplitude of fluctuation can reach the total length of lower swing arm, that existing vehicle chassis is too far behind to catch up.If lower swing arm amplitude of fluctuation need only the half of lower swing arm length, so horizontal concrete chute end only need slide 4% of lower swing arm length, if lower swing arm amplitude of fluctuation must reach the length of lower swing arm, so horizontal concrete chute end need slide 14% of lower swing arm length.
The utility model without particular/special requirement, as long as there is enough intensity, can directly be fixedly connected on wheel to bumper.
The utility model, for the design of transmission shaft and direction lever, can add upper cardan at two ends, and imitative the utility model structure design, the double wish-bone arm type hanging transverse rigidity that can match in excellence or beauty is large, the advantage that the anti-side amount of going all out is strong, and don't the effect affecting transmission and turn to.Be two at one stroke receipts.
The utility model is applicable to any vehicle chassis, comprises riding vehicle, lorry, low speed electric car, three-wheel vehicle, mobility scooter for old people and other be applicable to of the present utility model.
The utility model compared with prior art, has following effect:
1, the wheel of swing arm sliding-type independent suspension system is regardless of on various road surface, low, at a high speed, under the various state such as turning, camber angle does not change, wheel moves perpendicular to vehicle body all the time, makes the area of contact on its tire and ground maximum, have maximum grab ground ability, simultaneously Wheel centre distance all around parameter remain constant, significantly reduce the wearing and tearing of tire, wheel lifting moving wide ranges, the length distance of lower swing arm can be reached, improve off-road capability.
2, front brace, rear brace, lower swing arm define firmly triangular structure, and lateral stiffness increases, thus adds anti-side and incline, and anti-swing ability, reduces to take up room.
3, simply, occupy-place is few, does not affect the design of design and the driving device turned to, and front and back wheel all uses forward mounting to design, and can realize wheel 180 degree and turn to, can realize automobile cross running for lower swing arm, front and back brace structure.
4, pendulum arm length, brace length and connection angle adjustable range wide, its motion characteristics does not affect by device length, gradient, device is changeable can be oblique, installation direction can be selected arbitrarily in same level, to adapt to different installing spaces, increases the alerting ability of layout, reduce space occupy-place, be conducive to lowering the center of gravity.
5, the stroke range of super large, road surface strong adaptability is the desirable suspension platform of Active Suspensions or Pneumatic Suspension, is the ideal chose of mountain off-road car.
6, structure is simple, pure triangle physical structure, and reliability 100% is practical.It is the best replacement technology of existing conventional suspension.
7, production process is simple, and low production program and cost, be applicable to Quantity production.
