一、技术领域1. Technical field
本实用新型涉及汽车悬架系统部件，特别涉及一种阻尼可调的能量回馈式汽车主动悬架电磁减振装置。The utility model relates to an automobile suspension system component, in particular to an energy feedback type automobile active suspension electromagnetic vibration damping device with adjustable damping.
二、背景技术2. Background technology
减振器是汽车悬架系统的重要零部件，其主要功能是吸收路面不平产生的振动，缓解路面带来的冲击，满足汽车运行过程中的乘坐舒适性和操纵稳定性要求。目前在汽车上常用的筒式液压减振器是利用活塞在活塞缸中运动时油液与活塞孔之间的摩擦以及油液分子间的内摩擦形成阻尼力，使汽车的振动能量转化为油液的热能，再由减振器散发到大气中。这种方式无法对振动的能量进行有效回收，造成了能量的浪费。同时，汽车在不同等级的路面上行驶以及加速、减速和转向等不同的工况下，车辆对减振器阻尼大小的要求不同，而传统的筒式液压减振器无法根据行车工况实时进行阻尼调节，限制了车辆乘坐舒适性和操纵稳定性的提高。The shock absorber is an important part of the automobile suspension system. Its main function is to absorb the vibration generated by the uneven road surface, alleviate the impact brought by the road surface, and meet the requirements of ride comfort and handling stability during the operation of the automobile. At present, the cylinder type hydraulic shock absorber commonly used in automobiles uses the friction between the oil and the piston hole when the piston moves in the piston cylinder and the internal friction between the oil molecules to form a damping force, so that the vibration energy of the automobile is converted into oil. The thermal energy of the liquid is then dissipated into the atmosphere by the shock absorber. This method cannot effectively recover the vibration energy, resulting in waste of energy. At the same time, when the car is driving on different grades of roads and under different working conditions such as acceleration, deceleration and steering, the vehicle has different requirements for the damping size of the shock absorber, and the traditional cylinder hydraulic shock absorber cannot be adjusted in real time according to the driving conditions. Damping adjustment limits the improvement of vehicle ride comfort and handling stability.
经文献检索发现，中国国家知识产权专利局于2005年1月5日公开了一项公开号为CN1559819A，名称为“车辆悬架用能量回馈型电磁减振装置”的专利申请。该技术提出利用直线发电机、电力变换器和能量存储单元进行能量回馈，通过控制功率晶体管的通断调节直线发电机的阻尼，但其阻尼仅能实现两级可调，且电路结构的安全性不高。中国国家知识产权局专利局于2012年10月05日公开了一项公开号为CN102700378A，名称为“电磁馈能型半主动悬架馈能阻尼实时控制装置及方法”的专利申请。该技术通过馈能电机、行星齿轮升速机构、滚珠丝杠和馈能控制电路实现能量回馈，通过改变馈能电机的充电电压对阻尼进行分级控制，但是所采用的滚珠丝杠机构和行星齿轮机构具有一定的机械传动损失，降低了减振器的能量回收效率。It is found through document retrieval that the State Intellectual Property Office of China published a patent application with publication number CN1559819A on January 5, 2005, entitled "Energy Feedback Electromagnetic Damping Device for Vehicle Suspension". This technology proposes to use linear generators, power converters and energy storage units for energy feedback, and adjust the damping of linear generators by controlling the on-off of power transistors, but its damping can only be adjusted in two stages, and the safety of the circuit structure not tall. The Patent Office of the State Intellectual Property Office of China published a patent application with the publication number CN102700378A on October 5, 2012, entitled "Electromagnetic Energy Feed Type Semi-Active Suspension Feed Energy Damping Real-time Control Device and Method". This technology realizes energy feedback through the energy feeding motor, planetary gear speed-up mechanism, ball screw and energy feeding control circuit, and controls the damping in stages by changing the charging voltage of the energy feeding motor, but the ball screw mechanism and planetary gear used The mechanism has a certain mechanical transmission loss, which reduces the energy recovery efficiency of the shock absorber.

本实用新型应用于由20个线圈绕组组成的电磁减振器构成的，一种阻尼可调的能量回馈式汽车主动悬架电磁减振装置的运行过程：The utility model is applied to the electromagnetic shock absorber composed of 20 coil windings. The operation process of an energy feedback type automobile active suspension electromagnetic shock absorber with adjustable damping:
在汽车行驶过程中，由于路面不平和加速、减速、制动等原因，车辆的簧载质量和非簧载质量的相对位置不断变化，导致电磁减振器的动子部分和定子部分发生相对运动，定子外筒1上的线圈绕组1-1至1-20不断切割动子上的永磁体2-2产生的磁感线，由电磁感应原理在线圈绕组1-1至1-20中感应出单相交变电流，该电流经过线圈绕组调节电路12和整流稳压电路10转变成直流电存储在车载蓄电池9中，从而将电磁减振器往复移动的动能转变为电能，实现了能量的回馈。永磁体2-2和线圈绕组1-1至1-20之间的电磁力形成了电磁减振器的阻尼。回馈的电能可以直接供给车辆的电子电气设备使用。During the driving process of the car, due to uneven road surface and acceleration, deceleration, braking and other reasons, the relative position of the sprung mass and unsprung mass of the vehicle is constantly changing, resulting in relative motion between the mover part and the stator part of the electromagnetic shock absorber. , the coil windings 1-1 to 1-20 on the stator outer cylinder 1 continuously cut the magnetic induction lines generated by the permanent magnet 2-2 on the mover, and are induced in the coil windings 1-1 to 1-20 by the principle of electromagnetic induction The single-phase alternating current is converted into direct current through the coil winding regulating circuit 12 and the rectifying and stabilizing circuit 10 and stored in the on-board battery 9, thereby converting the kinetic energy of the reciprocating movement of the electromagnetic shock absorber into electrical energy and realizing energy feedback.

When the digital signal is at a high potential, the triac is turned on, and the coil winding connected to the input pole i of the triac is turned on, inducing a current and generating a damping force; when the digital signal is at a low potential, the triac is disconnected , the coil winding connected to the input pole i of the bidirectional triode is disconnected, and the current cannot be induced to generate damping force. Therefore, the damping force of the electromagnetic shock absorber can be adjusted by connecting the number of coil windings 1-1 to 1-20 in the control circuit, so as to meet the requirements of different grades of road surfaces and improve the ride comfort of the car. Feedback control can be realized through the vehicle body vibration acceleration signal output by the acceleration sensor 13 .

Provide the best damping force, output control signal to the coil winding adjustment circuit 12, adjust the damping force of the shock absorber; the damping force of the four shock absorbers on the left and right sides and the front and rear sides can be controlled independently, thus Adjust the angle of the body to improve the handling stability of the car.
