Only there is good adaptability to the road surface input under specific operation, therefore effectiveness in vibration suppression is limited, and most of vibrational energy is all
It is dissipated in the form of thermal energy.
For the energy effective utilization for generating Vehicle Suspension Vibration, there has been proposed feed energy suspensions.Feed energy suspension
Refer to and replaces traditional damper using energy recycle device, the energy that Vehicle Suspension Vibration caused by Uneven road is generated
The novel suspending bracket system recycled.Currently, feed energy suspension can be divided into mechanical and electromagnetic type according to its principle, due to two
The mechanism construction of the energy conversion device of person is excessively complicated, and energy recovery efficiency is low and at high cost, therefore application is not very
Extensively.
Summary of the invention
The main object of the present invention is to propose that a kind of structure is simple, and rigidity is big, and the high novel energy regenerative of energy conversion efficiency is outstanding
Frame improves vehicle running smoothness to improve the dynamic response capability of suspension system.
In order to solve above-mentioned technical problem, the present invention designs a kind of minority carrier generation lifetime feed energy suspension system
It unites, device used in the system includes minority carrier generation lifetime, rotary ultrasonic motor, super capacitor and battery.It is described
Minority carrier generation lifetime can convert the vertical vibration of vehicle body to rotary motion, the mechanism include end execute platform,
It rotates moving platform and connects three identical branches of the two platforms, the rigid link of each branch and end execute
Platform passes through typed ball bearing pair with rotation moving platform and connects in the apex of each platform；The end execute platform by prismatic pair with
Spring carried mass connection, rotation moving platform are connect by revolute pair with rotary ultrasonic motor, and the end executes platform prismatic pair
Axis and the axis of rotation moving platform revolute pair are point-blank；The piezoceramic disk of the rotary ultrasonic motor is mounted on few freedom
It spends on the rotation moving platform of parallel institution, the frictional disk of rotary ultrasonic motor is connected between centers quality；The rotary ultrasonic electricity
After machine is connect with super capacitor, finally it is connect with battery.There are two freedom degree, Ke Yishi for above-mentioned minority carrier generation lifetime
Vertical movement is converted rotary motion by existing energy regenerative mechanism, and power supply machine power generation uses.
Compared with the prior art, the present invention has the following advantages
1, overall structure is symmetrical, simple, and large carrying capacity, rigidity mass ratio is big, and each branched structure is simple, and interchangeability is good,
It is easy installation and manufacture.
2, it can be used for automobile feed energy suspension, dynamic stroke is big, and flexibility is high, fast response time, low frequency and height for suspension
Frequency has good adaptability, recycles the high-efficient of energy.
3, piezoelectric material of the invention does not need to consume any energy, high reliablity, without the former vehicle power transmission of change
System, convenient for repacking, and the light weight and cost of additional firmware is low, does not also need frequently to replace battery in use.

Specific embodiment
Below with reference to specific example, the present invention is described in detail
Novel minority carrier generation lifetime feed energy suspension system authority schematic diagram described in Fig. 1 mainly includes lower-mobility
The automobile-used feed energy suspension of the compositions such as parallel institution, rotary ultrasonic motor (9), super capacitor (8) and battery (7), it is described to lack certainly
Platform (1), rotation moving platform (12) and three identical branches (4), (13), (15) groups are executed by end by degree parallel institution
At；It is equilateral triangle that the end, which executes platform (1) and rotation moving platform (12), and two platforms are parallel to each other, central shaft
Line is point-blank；Three branches (4), (13), (15) are executed by typed ball bearing pair (3) and typed ball bearing pair (6) and end
Platform (1) and rotation moving platform (12) hingedly, and between two platforms；Above-mentioned end executes platform (1) and passes through prismatic pair (2)
It is connect with sprung mass (16)；Rotation moving platform (12) is connected by the piezoceramic disk of revolute pair (5) and rotary ultrasonic motor (9)
It connects, the frictional disk of the rotary ultrasonic motor (9) and axle quality (10) are connected.
The automobile suspension system due to caused by Uneven road excitation or complicated road condition generates vibration, above-mentioned effect of vibration
Platform (1) is executed in end, rotation moving platform (12) can be made to occur forward or reverse in space, to drive rotary ultrasonic electric
Machine (9) power generation.For rotating moving platform (12) and rotate forward, i.e. compression travel, when effect of vibration executes on platform (1) in end
When, the end executes platform (1) and moves downward along the central axis upright of two platforms, above-mentioned branch (4), (13), (15)
Relative motion occurs in space, the space length for making end execute platform (1) and rotate between moving platform (12) reduces, while with
Its hinged rotation moving platform (12) branch (4), (13), (15) drive under do clockwise rotation, keep turn flat
Platform (12) drives the piezoceramic disk of rotary ultrasonic motor (9) and is connected on axle quality (10) frictional disk under the action of frictional force
Deformation occurs for its material surface, produces electricl energy.For rotating moving platform (12) reversion, i.e. diastole stroke works as bearing spring
(14) when unfolding, end execute platform (1) move upwards under force, above-mentioned branch (4), (13), (15) movement side
To occur immediately change, move round about, at this time end execute platform (1) with rotation moving platform (12) between space away from
From increase, at the same the rotation moving platform (12) hinged with it branch (4), (13), (15) drive under do counterclockwise rotation fortune
Dynamic, equally reverse moving platform (12) also will drive the piezoceramic disk of rotary ultrasonic motor (9) and be connected in axle quality (10) friction
For disk under the action of frictional force, allowing the piezoelectric material of piezoelectricity panel surface, deformation occurs, produces electricl energy.When above-mentioned undervibration is to draw
It when stretching or compress bearing spring (14), will not produce electricl energy, the variation of electric energy size changes with the deformation of material surface
Become.
The above-mentioned course of work, the portion of energy of body vibrations be electric energy can be converted by energy regenerative transformation mechanism, thus
This portion of energy is stored, supply automobile uses, and reduces dependence of the vehicle consuming system to vehicle power supply.
