Interconnecting piece, support portion, damping portion and turning part the wheel hub be located axially at two wheel hubs between.
The interconnecting piece includes Top Crossbeam 10 and lower cross arm 20, and the Top Crossbeam 10 and lower cross arm 20 are to 50 He of the wheel hub
Vehicle frame plays connection function.The Top Crossbeam 10 and lower cross arm 20 are hinged with the wheel hub 50 and vehicle frame, and the upper cross is made
Arm 10 and lower cross arm 20 can be rotated using the axis of horizontal direction as axis with the wheel hub 50 and vehicle frame connecting pin, to make
When a certain amount of bounce occurs in the vertical direction for the wheel hub 50, the vibrations being transmitted on the vehicle frame are reduced, it will not be to vehicle
Frame causes prodigious influence.Preferably, the Top Crossbeam 10 and lower cross arm 20 are arranged with the junction of the wheel hub 50 and vehicle frame
There are rubber bushing, the rubber bushing that can further decrease the vibrations of the wheel hub 50 influence caused by vehicle frame.Preferably, institute
It states Top Crossbeam 10 and lower cross arm 20 is all made of the A shaped steel of high rigidity, to improve the intensity of the transverse arm 10 and the lower cross arm 20.
The support portion is air bag 30, and one end of the air bag 30 is connect with the Top Crossbeam 10, the other end and the vehicle
Frame connects, the main by weight for carrying the car.Due to the air bag 30 can occur under pressure it is a certain amount of
Deformation so that the air bag 30 can absorb the vibrations that most of wheel hub 50 generates, to avoid causing to the vehicle frame
Excessive influence.Preferably, the support portion, which can also be arranged to other structures, such as spring, resilient rubbber cushion etc., has elasticity
Structure, alternatively, the combination of a variety of different structures is can also be, as long as damping can be played the role of.
The damping portion includes damper 40, it is preferable that the damper 40 is hydraulic damper, the damper 40
One end is connect with the lower cross arm 20, and the other end of the damper 40 is connect with the vehicle frame.The damper 40 was used for
Filter the vibrations that the lower cross arm 20 is transferred on the vehicle frame.Preferably, the damping portion may be arranged as spring, alternatively,
The damping portion can also be spring and the structure that hydraulic damper combines, to further increase damping effect.
The turning part includes rocking arm 60, and the rocking arm 60 is connect by rocking arm hold-down support with vehicle frame, 60 energy of the rocking arm
Enough shaft rotations on rocker arm support vertical direction are dynamic, and one end of the rocking arm 60 is connect with track rod 80, the steering
Drag link 80 is connect with the wheel hub 50, and the wheel hub 50 can be driven to rotate around stub, to realize the work(of steering
Energy.The rocking arm 60 of two turning parts is connected by connecting rod 61, so that two rocking arms 60 can realize linkage,
Two can be controlled simultaneously by the steering mechanism by only needing one of them described rocking arm 60 to be connect with the steering mechanism of car
The rocking arm 60 acts, to make two wheel hubs 50 realize synchronous turn to.Preferably, the connecting rod 61 is located at two institutes
State the part between wheel hub 50 and be formed in structure recessed on vertical direction, between two wheel hubs 50 wiring or its
His structure provides the installation space of bigger, from the structure installed between two wheel hubs 50 of reduction to the occupancy of interior space.
One in two rocking arms 60 connect with the steering mechanism of car, another connect with damper 70, described
Damper 70 is also connect with the vehicle frame.When the rocking arm 60 drives the relatively described vehicle frame of the wheel hub 50 to rotate, institute
Certain damping force can be generated by stating damper 70, and when the steering mechanism remove to the active force of the rocking arm 60 when
It waits, the damper 70 can give the rocking arm 60 to provide driving force, make the rocking arm 60 that the wheel hub 50 be driven to be restored to just
Beginning position, to realize the wheel hub 50 can after steering self-aligning function.Preferably, in other embodiments, institute
Can also be arranged by stating damper 70 by two, and two dampers 70 are connect with two rocking arms 60 respectively, two resistances
70 synchronization action of Buddhist nun's device is capable of providing the driving force of bigger, so as to preferably drive the wheel hub 50 to rotate.
Preferably, in other embodiments, the connecting rod 61 can also be not provided with, make two rocking arms 60 simultaneously with
The steering structure of the car and the damper 70 connect, to make two rocking arms 60 can be with synchronization action.
The wheel hub 50 is additionally provided with braking system for installing tire on the wheel hub 50.The wheel hub 50 is logical
It crosses the interconnecting piece and the support portion and realizes connection with the vehicle frame, and pass through the turning part and control steering.
The suspension system provided by the invention, due to being not provided with connection structure between two wheel hubs 50 so that
Two wheel hubs 50 can be relatively independent movement, to reduce two wheel hubs 50 between influencing each other, make suspension
System overall comfort is more preferable.Simultaneously as being not provided with connection structure and dependency structure between two wheel hubs 50, also make
Obtain the weight smaller of the suspension system.Also, the structure of the suspension system is simpler so that the suspension system installation
The space occupied smaller when on to car, enables interior space bigger.Further, due to the upper cross of the interconnecting piece
Arm 10 and lower cross arm 20 use the rigid structure of high rigidity A types so that the span between two support portions can be with bigger, such as two
Span between a support portion can reach 1200-1300mm, to improve the lateral stability of car.
The present invention also provides a kind of car, the car includes above-mentioned suspension system, it is preferable that the suspension system is used for
The front driving wheel of the car is set.Since above-mentioned suspension system is arranged in the car so that the inner space of car can be more
Greatly.Specifically, the interconnecting piece, support portion, turning part and damping portion are connected with the wheel hub, that is, are all disposed within the car
Both sides so that the suspension system occupies smaller to the central space of car, especially internal to make the car height
Floor level can be lower, keeps the position of centre of gravity of car lower, increases the stability of vehicle traveling.Due to the suspension system
The distance between two described wheel hubs can with bigger, to make the width of the car can be with bigger, especially car inside
Channel width can be with bigger, such as can reach 700-900mm, so that passenger is moved in the car more convenient, shortens passenger or more
The time of vehicle improves efficiency of operation.
Those skilled in the art will readily recognize that under the premise of not conflicting, above-mentioned each preferred embodiment can be free
Ground combination, superposition.
It should be appreciated that above-mentioned embodiment is merely exemplary, and not restrictive, without departing from the basic of the present invention
