Brief description of the drawings
Fig. 1 is the structural representation of motorcar electric shock absorber provided by the invention.
Embodiment
In order to be better understood from technical scheme, implementation provided by the invention is described in detail below in conjunction with the accompanying drawings
Example.
The embodiment of the present invention provides a kind of automobile damper, as shown in figure 1, it includes：Motor 107, electric expansion bar, branch
Spring 103, two pressure sensors, electric expansion bars are supportted, the electronic telescopic rod includes：Cylinder body 110, push rod 111 and leading screw,
Wherein：
The motor 107 connects one end of push rod 111 by lead screw transmission, specifically, the power transmission shaft and silk of the motor 107
Thick stick is connected, and one end of the push rod 111 and at least a portion are arranged in the cylinder body 110, one end of the cylinder body 110
It is fixed on the motor 107, the other end of the cylinder body 110 is fixedly installed first flange 102, the first flange 102
On be provided with first pressure sensor 105, the other end of the push rod 111 stretches out the another of the cylinder body 110 and the push rod 111
One end is fixedly installed second flange 101, and second pressure sensor 104 is arranged on the other end of push rod 111, the first pressure
Support spring 103 is provided between sensor 105 and the second flange 101, the support spring 103 is enclosed on the push rod
On 111.
In other embodiments, on the basis of above-described embodiment, further, the first company is provided with the motor 107
Joint chair 109, the second connecting seat 106 is provided with the second sensor 104.Filled in order to which the motorcar electric shock absorber is fixed
It is located in the car body of automobile.Other embodiment, can be in a manner of buckle as needed or welding, screw installation by the vapour in
The electronic shock absorber of car is fixedly connected in car body.
In other embodiments, on the basis of above-described embodiment, further, the motorcar electric shock absorber also includes：Add
Velocity sensor 112, the acceleration transducer are arranged on the motor, electric expansion bar, support spring, two pressure sensings
Any position of device or the either component of electric expansion bar.
In other embodiments, on the basis of above-described embodiment, further, the motorcar electric shock absorber also includes：GPS
Sensor 108, the GPS sensor 108 be arranged on the motor, electric expansion bar, support spring, two pressure sensors or
Any position of the either component of electric expansion bar.
The motor, first pressure sensor, second pressure sensor, GPS sensor and acceleration transducer all connect car
Controller on body, controller judge that to be adjusted to the electronic shock absorber controller can also be independent according to control
It is integrated use in the presence of or with other in-car controllers, the controller can also be provided separately within the motor, electronic stretch
Contracting bar, support spring, two pressure sensors or electric expansion bar either component any position.
In actual use, each car installs four embodiment of the present invention and provides four above-mentioned shock absorbers.Two front shock-proof devices
Device, two rear shock absorbers.
Each shock absorber, according to road conditions, the size of adjust automatically power output.
For example when vehicle passes through deceleration strip, in ramp up, wheel rises, and support spring forced compression shortens, vehicle body
It can move upwards, the pressure that now two pressure sensors detect is different, and the pressure of second pressure sensor is more than the first pressure
The pressure of force snesor, then shunk by controller to motor signal, the push rod of electric expansion bar, help support spring contracting
It is short, make first pressure sensor identical with the pressure of second pressure sensor, then vehicle body imperceptible support spring support force
Change, vehicle body stress is constant, will not move up and down, and vehicle body keeps stable.
When vehicle passes through deceleration strip, in the descending stage, support spring stress reduces, and support spring is elongated, now two pressures
There is difference in the pressure that force snesor detects, and the pressure of second pressure sensor is less than the pressure of first pressure sensor, then
By controller to motor signal, push rod elongation, support spring elongation is helped, makes the pressure of two sensors identical, then vehicle body
The change of the support force of imperceptible support spring, vehicle body stress is constant, will not move up and down, and vehicle body keeps stable.
When braking, it is negative value that acceleration transducer, which detects acceleration, is pressed according to acceleration transducer numerical value and two
The difference of force snesor, increase the output length of the push rod of front shock-absorber, prevent vehicle's center of gravity from leaning forward, during vehicle brake will not before
Pour point head.
When a vehicle is started, it is on the occasion of according to acceleration transducer numerical value and two that acceleration transducer, which detects acceleration,
The difference of individual pressure sensor, shorten the length of front shock-proof device push rod, prevent vehicle nose.
When the vehicle is turning, acceleration transducer detects transverse acceleration, increases the length of the push rod of outside shock absorber,
Prevent from rolling, keep vehicle stabilization.
When GPS sensor detect vehicle be in run at high speed pattern when, the length of the push rod of front shock-proof device is reduced, after increase
The length of the push rod of shock absorber, makes vehicle moderately lean forward, and increases earth-grasping force using blast, keeps vehicle stabilization traveling.
When pressure detector and acceleration transducer detect vehicle up and down motion frequency it is very high when (bumpy road), four
The length of the push rod of shock absorber all increases, and increases vehicle ground clearance, increases trafficability and comfort level.
When pressure detector and acceleration transducer detect vehicle up and down motion frequency it is not high when (gentle road surface), four
The length of shock absorber electric rod all shortens, and reduces vehicle ground clearance, makes vehicle more stable.
When detector detects vehicle stall, the push rod of all shock absorbers shortens, and reduces the road clearance.
A kind of automobile and its electronic shock absorber provided above the embodiment of the present invention is described in detail, for this
The those skilled in the art in field, according to the thought of the embodiment of the present invention, have change in specific embodiments and applications
Become part, in summary, this specification content should not be construed as limiting the invention.
