Description
Technical field
It the utility model is related to a kind of variation rigidity transverse arresting apparatus and the automobile using the transverse arresting apparatus.
Background technology
The QS of automobile is the anti-roll moments for increasing vehicle body in vehicle roll, reduces the angle of heel of vehicle body
Degree, strengthen the riding stability of vehicle.However, common QS is almost what is be fixed together with vehicle frame and vehicle bridge,
The roll angular rigidity of QS itself is constant, and when designing QS, roll angular rigidity is typically by maximum
Angle of heel is come what is matched, so in the small inclination of vehicle, the larger roll angular rigidity of QS can actually reduce vehicle
Ride performance.
Variation rigidity is provided with automobile disclosed in the Chinese invention patent application that application publication number is CN104369640A
Transverse arresting apparatus, the transverse arresting apparatus includes being arranged on QS in vehicle bridge, and QS is in U on the whole
Type, two support arms of QS have been respectively articulated with suspension rod, and rocking arm is hinged with suspension rod, and one end of the remote suspension rod of rocking arm is hinged
On vehicle frame, the be hinged central axis and suspension rod of rocking arm prolong with the be hinged central axis of support arm hinged place along width of the carbody direction
Stretch, rubber block is installed with vehicle frame, has on rocking arm and is used to rubber block pushing tow match somebody with somebody when rocking arm turns to setting position
The pushing tow face of conjunction, free gap is left between pushing tow face and rubber block before swinging rotary to above-mentioned setting position.
When vehicle travels on roughness pavement, vehicle frame produces small inclination, and the relative motion between vehicle frame and vehicle bridge will
QS is forced to produce torsion, the QS of torsion will drive rocking arm to rotate by suspension rod, due to free gap
In the presence of before above-mentioned setting position is turned to, QS is in zero stiffness area, is turning to above-mentioned setting position and rubber
When glue block pushing tow coordinates, due to the elastic deformation of rubber block, QS is in Low rigidity area, is rotated further in rocking arm
To rubber block substantially no longer compression when, rocking arm and vehicle frame form fixing assembling, and QS is in high rigidity area.When
When vehicle frame produces the inclination of smaller angle, the QS in zero stiffness area or Low rigidity area can be effectively improved the flat of vehicle frame
It is pliable, ride comfort is improved, when vehicle frame produces the inclination of greater stiffness, the QS in high rigidity area can be effective
Anti- rolling capability is improved, improves safety concerns.
But the size of free gap and the performance decision transverse direction of rubber block are fully relied in above-mentioned transverse arresting apparatus
The variable rigidity property of stabilising arrangement, free gap are higher to requirement on machining accuracy, if it is desired to obtain higher variable rigidity property
If, it is necessary to the performance of rubber block is improved, cost increase is larger.In addition, in this transverse arresting apparatus, to ensure vehicle body
Maximum, which rolls, to be required, need to be matched thicker stabiliser bar, be increased nonspring carried mass and cost.Moreover, this transverse arresting apparatus is main
Effect is actually to be used to improve stability of the vehicle under small inclination, can not greatly improve the anti-rolling capability of vehicle.Separately
Outside, for vehicle when swerving or vehicle body has larger inclination, rocking arm can extrude rubber block, because rocking arm end stress is larger,
Cause rubber block deformation big, it is fragile.
