Crosslinked disappearing turns round active lateral stabilizer rod system
Technical field
The utility model relates to field of automobile suspension, particularly relates to a kind of crosslinked disappearing that can control vehicle roll angle and vehicle body torque load being applicable to various vehicle and turns round active lateral stabilizer rod system.
Background technology
For obtaining good riding comfort, the suspension rate of vehicle designs less usually, and when turning in running at high speed, vehicle body can produce very large transverse direction and roll and Traverse angular vibration.For reducing this lateral inclination, often in suspension, add Panhard rod, wherein with the most use is rod-type Panhard rod.
At present, that most vehicle is installed or passive inhead type (see figure 1) or underneath type (see figure 2) forward and backward anti-roll bar suspension, its structure is exactly directly be hinged at independently on auto body by the connecting rod (underneath type) that the both sides of forward and backward Panhard rod (inhead type) or two side ends are hinged, and front and back Panhard rod is mutually independently.Vehicle both sides Suspension Deformation not wait and when vehicle body is relative to road-bank elevation, Panhard rod can be reversed thus be hindered the distortion of axle spring, thus reduce lateral inclination and the Traverse angular vibration of vehicle body to a certain extent.
But due to the inertia of automobile sport, the effect of inclining of the anti-side of this passive lateral stability pole pair suspension is delayed and is limited.When automobile is in tilted road surface traveling or when turning to, this kind of suspension frame structure can not eliminate the angle of roll of vehicle body generation, and vehicle riding comfort and operational stability are difficult to take into account.When running car is on uneven road surface, stronger horizontal stabilizer bar structure, though there is stronger anti-side to incline effect, but but can increase the torque load that road surface produces vehicle body, the adhesion condition on wheel and ground is deteriorated, increases the impact that road surface is transmitted, vehicle riding comfort is deteriorated.
At present, the breakaway-element active lateral stabilizer rod that indivedual car is applied to some extent is that Panhard rod is broken as two parts in transverse part office, and makes two parts produce relative motion by HM Hydraulic Motor or motor.The distortion of Panhard rod is changed by the rotation of hydraulic control motor or motor.But connect the actuator configurations relative complex of Panhard rod in this kind of mechanism, make Panhard rod lateral part intermediate sizes comparatively large after actuator is installed, arrange inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of crosslinked disappearing and turns round active lateral stabilizer rod system, the vehicle roll angle of automobile when uneven road surface traveling or steering situation and the twist moment suffered by vehicle body can be controlled, improve the tack on wheel and ground, improve operational stability and the riding comfort of vehicle.
