Description
Technical field
The utility model relates to automobile chassis, in particular to a kind of double V word swing arm slidingtype independent suspensions.
Background technique
Independent Suspension developed over more than 80 years, the riding stability of automobile, comfort, safety, ride comfort and cross-country
Property, all closely bound up with the suspension system in chassis structure, present car mostly uses independent suspension system, according to its structure shape
Formula is different, and it is only that independent suspension system is broadly divided into Mai Fuxunshi independent suspension system, double fork arm type equal independent suspension systems, multi link
Vertical suspension system, towed independent suspension system etc..Performance of the Mai Fuxunshi independent suspension system on road-ability still enables
People is satisfied, but it is configured to straight barrel type, lacks barrier force to the impact of left and right directions, cannot significantly go up and down chassis height, and
And camber angle changing rule is undesirable.Other independent suspension systems also go up and down chassis to inclination, substantially, camber angle becomes
Change, starting, brake " nodding ", center of gravity is high, turning speed it is too fast it is easy overturn etc., all have the defects that it is different degrees of, cannot be simultaneously
Take into account its excellent performance.Rigid axle suspension comfort, ride comfort is poor, heavy goods vehicle and easily causes pavement damage.
Utility model content
Purpose of the utility model is to solve prior art problem, provide that a kind of camber angle is unchanged, wheel
Perpendicular to vehicle body bounce lifting moving range it is wide, anti-side is inclined, anti-swing strength can arbitrarily adjust by force damping, actively adjust lifting,
Respond a kind of rapidly double V word swing arm slidingtype independent suspensions.
In order to achieve the above objectives, the technical scheme adopted by the utility model is that: a kind of double V word swing arm slidingtypes independently hang
Frame, including V word lower swing arm, lower linear guide, the first control slide bar, the second control slide bar, V word upper swing arm, third control slide bar, the 4th control
Slide bar, damper, upper linear guide, hub bearing seat, lower linear guide are horizontally fixed on automotive frame, V word lower swing arm one
End is movably connected in the sliding end of lower linear guide, and the V word lower swing arm other end is movably connected on hub bearing seat, and the first control is slided
Bar, second control slide bar one end are respectively and movably connected to the midpoint of V word lower swing arm, and the first control slide bar, second control the another of slide bar
End is respectively and movably connected on the outside of vehicle body on vehicle frame or cross rail outer end, with tie point of the V word lower swing arm on hub bearing seat
Point-blank, with vehicle body parallel, upper linear guide is horizontally fixed on automotive frame, and the word upper swing arm one end V is flexibly connected
It is movably connected on hub bearing seat in the other end of the sliding end of upper linear guide, V word upper swing arm, third control slide bar, the 4th
One end of control slide bar is respectively and movably connected to the midpoint of V word upper swing arm, the other end difference of third control slide bar, the 4th control slide bar
It is movably connected on the outside of vehicle body on vehicle frame or cross rail outer end, with tie point of the V word upper swing arm on hub bearing seat at one
On straight line, with vehicle body parallel, damper one end is connected on vehicle frame, and the damper other end is connected on hub bearing seat, or even
Connect the road wheel end in V lower swing arm.
The linear guide is sliding rail or linear bearing.
The linear guide can independent design be fixed on automotive frame, can also be directly on design vehicle crossbeam.
The flexible connection is pivot pin connection or universal connection.
The first control slide bar, the second control slide bar, third control slide bar, the 4th control slide bar are linear or arc.
The first control slide bar, the second control slide bar can be designed in the two sides or side of V word lower swing arm.
The third control slide bar, the 4th control slide bar can be designed in the two sides or side of V word upper swing arm.
V word lower swing arm double end end passes through linear guide respectively and connect with automotive frame, V word lower swing arm single head end and wheel
Hub bearing block is flexibly connected.
V word lower swing arm double end end is flexibly connected with hub bearing seat respectively, and V word lower swing arm single head end is led by straight line
Rail is connect with automotive frame.
The utility model first controls slide bar, and the second control rod design is linear, is practically applicable to rear suspension；First control slide bar,
Second control rod design is arc, or does not influence the shape of wheel steering, is practically applicable to front suspension.V word lower swing arm, the first control are slided
Bar, the second length, link position, shape for controlling slide bar can make the appropriate adjustments with the requirement of different automobiles.
The utility model increases one group of swing arm, enhances wheel to lateral force resistance, has subtracted lateral suffered by damper
Power, damper can be placed flexibly, and space is saved.
Its V word lower swing arm road wheel end of the utility model is extended to as far as possible on wheel center of effort line, to reduce wheel to upper
The lateral pressure of swing arm, V word lower swing arm, control slide bar forms triangular structure and effectively antagonizes the lateral force that wheel is received, so its transverse direction
Rigidity is big, and anti-roll force is strong.
The utility model is to cancel out each other to be in line principle and design using double pendulum effects, and the theoretical upper deviation is 0, described
Linear guide only allows V word lower swing arm level to slide, V word lower swing arm road wheel end generated pendulum effect when moving vertically
The pendulum effect that the control slide bar being connected on A word lower swing arm generates is offset, and control slide bar limits the lower swing arm swing of V word, only
Allow V word lower swing arm to be vertically moved, forms theory and effect that wheel absolute upright moves along a straight line in vehicle body, now
Swing of the general manufacturing technology precision controlling between 0.01 1 0.03mm, for the wheel about 20mm of the prior art
Deviation can not mention in the same breath, and amplitude of fluctuation is up to the total length of V word lower swing arm.If V word lower swing arm amplitude of fluctuation only needs V
The half of word bottom arm lengths, then linear guide need to only slide the 4% of V word bottom arm lengths, if V word lower swing arm amplitude of fluctuation
The length that V word lower swing arm need to be reached, then linear guide need to only slide the 14% of V word bottom arm lengths.
Design of the utility model for transmission shaft and steering yoke can increase sliding type universal joint or imitative the utility model
Structure design.
