It presses thrust device and adjusts heavy ball 6.
The sliding rail 3 has two, and the central axes about automobile are symmetrical, and transmission shaft both sides, avoid on chassis 1
The tune heavy ball 6 of enough quality is failed to lay down due to vehicle frame length tonifying for the deficiency；The sliding rail 3 is that cross sectional shape is the thin of upside-down trapezoid
Wall construction, both ends open reduce the space occupied as far as possible；Sliding rail 3 is forged and pressed by the steel plate of 3mm, upper rim with
Horizontal plane is parallel, and width 20mm has equidistantly distributed bolt mounting holes above, is connect by bolt with vehicle chassis, length
It is adjusted according to the wheelbase of used vehicle, between 1m~1.5m,
The hydraulic thrust device is mounted on the both ends of sliding rail 3, is telescopic hydraulic pressure single plunger pump, including hydraulic oil
Cylinder 4 and hydraulic plunger 5；The end face of the hydraulic cylinder 4 is with the end face of sliding rail 3 in same vertical plane；The liquid
Hydraulic plunger 5, which heads on, adjusts heavy ball 6.The hydraulic plunger 5 is always positioned at except hydraulic cylinder 4, and the end face of hydraulic plunger 5 heads on two
The tune heavy ball 6 at end, hydraulic plunger 5 are always positioned in sliding rail 3, prevent from that heavy ball 6 is adjusted to deviate from sliding rail 3, hydraulic plunger 5 is pushed away by flexible
It is dynamic that the rolling change position in sliding rail 3 of heavy ball 6 is adjusted to achieve the effect that adjust centroid position；It is arranged in the hydraulic thrust at 3 both ends of sliding rail
Power apparatus and the tune heavy ball 6 inside sliding rail equally have two sets, and weight is adjusted to do resistance when glomeration can reduce driving, section
The about energy, and drive actions can be made more fast；The direction of motion of the hydraulic plunger 5 at both ends is on the contrary, displacement and rate travel phase
Together, to ensure not having gap between tune heavy ball 6, in case freely rolling for ball causes to adjust weight shakiness.Since the present apparatus is additionally to add
It is added on vehicle, therefore the present apparatus is suitable for the vehicle that sedan limousine or caravan etc. pursue control stability.The hydraulic thrust dress
That puts pushes stroke and speed according to the driving state of the vehicle as when turning radius and turning speed, the gradient, acceleration or braking
Acceleration etc. changes and adjusts, it is ensured that reaches best regulating effect within the shortest time.
The tune heavy ball 6 is linearly distributed in sliding rail 3, tangent between adjacent two ball, each diameter phase for adjusting heavy ball 6
Together；The lead that 6 material of heavy ball is larger for density is adjusted, outside chromium plating prevents from adjusting 6 corrosion of heavy ball, and can prevent lead contamination.Adjust weight
The quality of ball 6 accounts for the 15%-20% of vehicle entirety, needs with reference to depending on vehicle bottom space；3 length of sliding rail is vehicle wheelbase
80%.The upper plane of the guide rail 3 is tangent with adjusting heavy ball 6.Barycenter by the mobile change vehicle for adjusting 6 position of ball,
6 barycenter of tune heavy ball in same sliding rail point-blank contacts with each other between front and rear two ball, ensures to adjust heavy ball 6 can be according to
Controller 14 is by moving the instruction of hydraulic thrust device.
The rubber sheet gasket 2 is mounted between sliding rail 3 and chassis 1, reduces the vibration that vehicle frame is passed on weight adjusting device, rubber
2 thickness of gasket is 3mm, and the elasticity of rubber sheet gasket 2 can adjust heavy ball 6 and the chassis 1 on top tangent, and big spy is damped using it
Property to absorb reduce the vibration transmitted of vehicle, prevent from beating when heavy ball 6 being adjusted to be impacted.
Embodiment one
Turn condition.Steering angle sensor 11 measures vehicle and is in turn condition, suspension position sensor in this case
12 measure the centroid position of vehicle by measuring the position of each suspension.If the displacement that left front bearing spring measures is xlf, unit
For mm, the displacement that right front suspension spring measures is xrf, unit mm, the displacement that left rear suspension spring measures is xlr, unit
For mm, the displacement that right rear suspension spring measures is xrr, unit mm, each spring and the angle of vehicle axis system z-axis are respectively
θlf、θrf、θlr、θrr.The tensible rigidity of each bearing spring is respectively klf、krf、klr、krr, a length of l of front overhangf, a length of l of rear overhangr, axis
Distance is c, then distance of the barycenter of vehicle away from front axle
This distance is made comparisons with the neutral steering point that vehicle provides away from front axle distance, to vehicle centroid to neutral steer
The adjustment of point direction, control module send a signal to hydraulic thrust device, adjustment barycenter to neutral steering point close to even overlapping,
Vehicle is made to have the characteristic of neutral steer.
Embodiment two
Acceleration or upward slope state.Road speed sensors 8 measure the travel speed of vehicle, coordinate shift sensor 13 and
Throttle position sensor 9 predicts the acceleration of vehicle, because overtaking other vehicles acceleration or upward slope for experienced driver
When can use low grade.Barycenter is adjusted forward at this time, i.e., hydraulic plunger 5, which pushes, adjusts heavy ball 6 to be moved to headstock direction, offsets because adding
The torque that speed generates；If detecting driving force deficiency when going up a slope, barycenter to driving wheel direction need to be adjusted, increase tire
Adhesive force improves the driving force of vehicle
Embodiment three
Descending or the situation of braking.In braking, the barycenter of vehicle can be moved along, and front-wheel adhesive force is caused to increase, after
The situation that adhesive force reduces is taken turns, be easy to cause rear lock, the brake signal of brake signal sensor acquisition at this time, suspension position passes
Sensor acquires distribution of weight signal, monitoring and pre- measuring acceleration, and the transfer amount of barycenter is obtained after ECU is calculated, is then signaled
Barycenter is adjusted backward accordingly to hydraulic thrust device.
From the foregoing, it will be observed that the utility model can adjust vehicle centroid according to car steering situation, it is excessively curved to effectively improve vehicle
When control stability, improve accelerate or go up a slope when wheel adhesion condition, improve emergency braking when brake force.Sensor will
The driving condition of vehicle is transmitted to controller 14 in real time, forms the reponse system of a closed loop so that barycenter can also be adjusted in real time；
Weight is adjusted to do resistance when glomeration can reduce driving, it is energy saving, and drive actions can be made more fast.
