一种汽车减振器振动能量回收装置Vibration energy recovery device for automobile shock absorber

技术领域technical field

本实用新型涉及汽车节能技术领域，尤其涉及汽车能量回收装置，具体地说，涉及一种汽车悬架系统振动能量回收装置。The utility model relates to the technical field of automobile energy saving, in particular to an automobile energy recovery device, in particular to an automobile suspension system vibration energy recovery device.

背景技术Background technique

悬架系统作为汽车底盘系统的重要总成之一，悬架系统通常由减振器和减振弹簧共同组成。当汽车车架或车身与车轮之间相对运动时，悬架系统中减振器保持着往复直线运动。为改善汽车行驶过程中的乘坐舒适性，悬架系统的减振弹簧在受到路面不平的冲击时会产生振动，而减振器用于衰减悬架系统的振动能量。汽车悬架系统的减振器广泛采用筒式液力减振器，其工作原理是：当车架或车身与车轮之间出现相对运动时，减振器内的活塞上下运动，减振器腔内的油液反复地从一个腔经过不同阻尼孔流入另一个腔内，此时孔壁与油液间的摩擦和油液分子间的内摩擦对振动形成阻尼力。据统计，悬架系统减振器所消耗能量占发动机输出能量的很大比例，且路面越不平整，减振器消耗能量所占比例越大。在全球能源日趋紧缺的今天，充分回收汽车各部分能量并加以转化利用，对汽车降低油耗，减少排放具有现实意义。As one of the important assemblies of the automobile chassis system, the suspension system is usually composed of a shock absorber and a shock absorbing spring. When the car frame or body moves relative to the wheel, the shock absorber in the suspension system maintains a reciprocating linear motion. In order to improve the ride comfort during driving, the damping spring of the suspension system will vibrate when it is impacted by the uneven road surface, and the shock absorber is used to attenuate the vibration energy of the suspension system. The shock absorber of the automobile suspension system widely adopts the cylinder type hydraulic shock absorber. Its working principle is: when there is relative movement between the frame or the body and the wheel, the piston in the shock absorber moves up and down, and the shock absorber cavity The oil in the chamber repeatedly flows from one chamber through different damping holes into another chamber. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration. According to statistics, the energy consumed by the shock absorber of the suspension system accounts for a large proportion of the output energy of the engine, and the more uneven the road surface, the greater the proportion of the energy consumed by the shock absorber. Today, when global energy is increasingly scarce, fully recovering the energy of various parts of the car and converting it into use has practical significance for reducing fuel consumption and emissions.

如何设计一种能量回收装置用来回收车辆行驶过程中减振器的振动能量，目前国内外还未见相关装置的报道。因此，亟需设计一种减振器振动能量回收装置，能够在汽车行驶状态下实时回收减振器承载的振动能量，这对汽车的节能减排具有重要意义。How to design a kind of energy recovery device to be used for recovering the vibration energy of the shock absorber in the process of vehicle running, there are no reports of related devices at home and abroad at present. Therefore, there is an urgent need to design a shock absorber vibration energy recovery device that can recover the vibration energy carried by the shock absorber in real time when the vehicle is running, which is of great significance to the energy saving and emission reduction of the vehicle.

本实用新型的工作原理：Working principle of the utility model:

请参照图6，圆环形永久磁铁6的布置以图6为例，所述环形永久磁铁6的一端为N极，另一端为S极，相邻的任意两个所述环形永久磁铁6的同极面相对。所述环形永久磁铁6的磁通方向与动子轴线平行，相邻两个环形永久磁铁6的磁通方向相反，每个环形永久磁铁6的磁通从N极出发，通过与其相邻的动子磁极5及它与相应定子内环齿形成的气隙和筒形定子铁芯3，并绕过位于其上方的线圈绕组4，回到S极，形成磁力线回路。在汽车行驶过程中，减振器反复压缩和拉伸，活塞杆反复伸出和收缩，进而使动子与定子之间产生沿定子轴线方向的往复切割磁力线运动，进而在线圈绕组4内产生单相感应电动势，形成一个单相交流直线发电机。通过整流器10将单相交流直线发电机输出的单相交流电动势整流为直流，并充入蓄电池11，即可实现减振器振动能量的回收。Please refer to Fig. 6, the arrangement of circular permanent magnet 6 is taken Fig. 6 as an example, and one end of described circular permanent magnet 6 is N pole, and the other end is S pole, and the adjacent arbitrary two described circular permanent magnets 6 Opposite to the polar face. The magnetic flux direction of the annular permanent magnet 6 is parallel to the axis of the mover, the magnetic flux directions of two adjacent annular permanent magnets 6 are opposite, and the magnetic flux of each annular permanent magnet 6 starts from the N pole and passes through the adjacent moving element. The sub-pole 5 and its air gap formed with the corresponding stator inner ring teeth and the cylindrical stator core 3 bypass the coil winding 4 above it and return to the S pole to form a loop of magnetic force lines. During the driving process of the car, the shock absorber is repeatedly compressed and stretched, and the piston rod is repeatedly extended and contracted, thereby causing a reciprocating cutting magnetic field line motion between the mover and the stator along the axial direction of the stator, and then generating a single coil in the coil winding 4.

The rectifier 10 rectifies the single-phase AC electromotive force output by the single-phase AC linear generator into a direct current, and charges it into the battery 11, so that the vibration energy of the shock absorber can be recovered.
