Description
技术领域technical field
本发明涉及汽车横向稳定杆，尤其涉及汽车主动横向稳定杆。The invention relates to an automobile lateral stabilizer bar, in particular to an automobile active lateral stabilizer bar.
背景技术Background technique
目前，国内汽车上用的横向稳定杆大多是被动横向稳定杆，而国内对于车用主动横向稳定杆的自主开发能力尚还有待提高。现如今，很多厂家对主动横向稳定杆的研究只停留在控制系统和控制规律研究的层面，很少有人对横向稳定杆的结构加以研究。At present, most of the stabilizer bars used in domestic automobiles are passive stabilizer bars, while the domestic independent development capability of active stabilizer bars for vehicles still needs to be improved. Nowadays, many manufacturers' research on active stabilizer bars only stays at the level of control systems and control laws, and few people study the structure of stabilizer bars.
当汽车受到路面的冲击和在高速转向的情况下，汽车会发生侧倾，此时会给驾驶员带来不舒适感。横向稳定杆的主要作用是减小车身的侧倾角，提高驾驶员的操纵稳定性和舒适性。由于当前汽车上主要用的被动横向稳定杆对于阻抗车身侧倾的能力有限，尤其在汽车行驶在复杂路面的时候，很难满足汽车操纵稳定性和舒适性的要求。When the car is impacted by the road surface and turns at high speed, the car will roll, which will bring discomfort to the driver. The main function of the stabilizer bar is to reduce the roll angle of the vehicle body and improve the driver's handling stability and comfort. Due to the limited ability of the passive stabilizer bar mainly used in current automobiles to resist body roll, especially when the automobile is driving on complex road surfaces, it is difficult to meet the requirements of automobile handling stability and comfort.

The front ends of the left part of the stabilizer bar and the right part of the stabilizer bar are respectively fixed on the suspension, the second planet carrier on the left side of the planetary gear mechanism is used as an output end, and the left part of the stabilizer bar is used as a planet The output shaft of the second planetary carrier on the left side of the gear mechanism, the second planetary carrier on the right side of the planetary gear mechanism is used as another output end, and the right side of the stabilizer bar is used as the output shaft of the second planetary carrier on the right side of the planetary gear mechanism , the first ring gear on the left side and the first ring gear on the right side of the planetary gear mechanism are both engaged with the output end of the servo motor for transmission.

与现有技术相比，本发明的优点在于：Compared with the prior art, the present invention has the advantages of:
与国内现在广泛使用的被动横向稳定杆相比，采用本发明在被动横向稳定杆的结构上做了一些改变，并通过伺服电机把被动稳定杆变成主动稳定杆，从而克服了被动横向稳定杆对于阻抗汽车车身大侧倾角能力较小的问题。本发明的优点主要体现在以下三方面：Compared with the passive stabilizer bar widely used in China, the present invention makes some changes in the structure of the passive stabilizer bar, and turns the passive stabilizer bar into an active stabilizer bar through a servo motor, thereby overcoming the problem of passive stabilizer bar For the problem that the ability to resist large roll angles of the automobile body is small. The advantages of the present invention are mainly reflected in the following three aspects:
对于传统的被动横向稳定杆，当汽车车身发生侧倾时，被动横向稳定杆会发生扭转，从而产生阻抗车身侧倾的扭转力矩，但是，被动横向稳定杆产生的抗侧倾扭转力矩的大小取决于车身侧倾角的大小，具有被动性，属于被动安全领域；而对于本发明，当汽车车身发生大幅度侧倾时，本发明通过伺服电机可以改变抗侧倾力矩的大小，使汽车车身的侧倾角保持在要求范围内，从而弥补了被动横向稳定杆对于阻抗车身大幅度侧倾能力不足的缺陷、增加了汽车安全性和使驾驶员保持一定的路感，进而使驾驶员不会因车身大幅度侧倾而感到不适和产生疲劳，增加驾驶员的舒适性。同时，通过增加主动横向稳定杆的抗侧倾扭转力矩，增加了左右悬架的抗侧倾刚度，从而改变了左右轮胎的载荷，进而提高了汽车的操纵稳定性。For the traditional passive stabilizer bar, when the car body rolls, the passive stabilizer bar will be twisted, thereby generating a torsional moment that resists the body roll. However, the anti-rolling torsional moment generated by the passive stabilizer bar depends on Due to the size of the roll angle of the vehicle body, it is passive and belongs to the field of passive safety; and for the present invention, when the vehicle body rolls greatly, the present invention can change the size of the anti-rolling moment through the servo motor, so that the vehicle body The roll angle is kept within the required range, thus making up for the lack of passive anti-stabilizer bars in resisting the large roll of the vehicle body, increasing the safety of the car and maintaining a certain sense of road for the driver, so that the driver will not be affected by the vehicle body. Discomfort and fatigue caused by a large roll, increasing the driver's comfort. At the same time, by increasing the anti-roll torsional moment of the active stabilizer bar, the anti-roll stiffness of the left and right suspensions is increased, thereby changing the load on the left and right tires, thereby improving the handling stability of the car.

本实施例中，伺服电机17固定在承载式车身19上，行星齿轮机构左侧第二齿圈18和行星齿轮机构右侧第二齿圈3均固定在承载式车身19上，伺服电机17通过伺服电机输出端锥齿轮1驱动行星齿轮机构左侧第一齿圈11和行星齿轮机构右侧第一齿圈2，伺服电机输出端锥齿轮1和行星齿轮机构左侧第一齿圈11和行星齿轮机构右侧第一齿圈2通过锥齿外啮合传动，此时，伺服电机17的转速进行一级减速，扭矩一级增加，并且，行星齿轮机构左侧第一齿圈11和行星齿轮机构右侧第一齿圈2的转动方向相反，行星齿轮机构左侧第一齿圈11和行星齿轮机构右侧第一齿圈2分别带动行星齿轮机构左右两侧的行星齿轮机构转动，且两侧对应齿轮和行星架的力矩大小相等和转动方向时刻相反。现以右侧为例说明动力传递过程如下：In this embodiment, the servo motor 17 is fixed on the load-bearing body 19, the second ring gear 18 on the left side of the planetary gear mechanism and the second ring gear 3 on the right side of the planetary gear mechanism are fixed on the load-bearing body 19, and the servo motor 17 passes The bevel gear 1 at the output end of the servo motor drives the first ring gear 11 on the left side of the planetary gear mechanism and the first ring gear 2 on the right side of the planetary gear mechanism, and the bevel gear 1 at the output end of the servo motor and the first ring gear 11 on the left side of the planetary gear mechanism The first ring gear 2 on the right side of the gear mechanism is driven by the external meshing of bevel teeth. At this time, the speed of the servo motor 17 is decelerated by one stage, and the torque is increased by one stage. Moreover, the first ring gear 11 on the left side of the planetary gear mechanism and the planetary gear mechanism The rotation direction of the first ring gear 2 on the right is opposite. The first ring gear 11 on the left side of the planetary gear mechanism and the first ring gear 2 on the right side of the planetary gear mechanism respectively drive the planetary gear mechanisms on the left and right sides of the planetary gear mechanism to rotate, and the two sides The magnitude of moment corresponding to the gear and the planet carrier is equal and the direction of rotation is opposite at all times. Now take the right side as an example to illustrate the power transmission process as follows:
行星齿轮机构右侧第一齿圈2与伺服电机输出端锥齿轮1外啮合，动力由伺服电机17传递到行星齿轮机构右侧第一齿圈2，此时伺服电机17的转速进行一级减速，并且扭矩一次增加，从而行星齿轮机构右侧第一齿圈带动行星齿轮机构右侧第一行星齿轮8转动，同时，行星齿轮机构右侧第一行星架7做公转转动，行星齿轮机构右侧第一行星齿轮8带动行星齿轮机构右侧第一太阳轮9转动，进而带动行星齿轮机构右侧第二太阳轮6转动，并将动力传递到行星齿轮机构右侧第二行星齿轮4，此时伺服电机17的转速进行二级减速，并且扭矩二次增加，进而带动行星齿轮机构右侧第二行星架5转动，由于行星齿轮机构右侧第二行星架5作为行星齿轮机构右侧的输出，并且通过花键与横向稳定杆右侧部分20连接，此时，动力由伺服电机17通过二次减速增扭传递到横向稳定杆右侧部分20，而横向稳定杆右侧部分20与承载式车身19通过衬套连接，从而可以控制承载式车身19的侧倾角的大小。The first ring gear 2 on the right side of the planetary gear mechanism is externally meshed with the bevel gear 1 at the output end of the servo motor, and the power is transmitted from the servo motor 17 to the first ring gear 2 on the right side of the planetary gear mechanism. At this time, the speed of the servo motor 17 is decelerated by one stage , and the torque increases at one time, so that the first ring gear on the right side of the planetary gear mechanism drives the first planetary gear 8 on the right side of the planetary gear mechanism to rotate, and at the same time, the first planetary carrier 7 on the right side of the planetary gear mechanism performs revolution rotation, and the right side of the planetary gear mechanism The first planetary gear 8 drives the first sun gear 9 on the right side of the planetary gear mechanism to rotate, and then drives the second sun gear 6 on the right side of the planetary gear mechanism to rotate, and transmits the power to the second planetary gear 4 on the right side of the planetary gear mechanism. The rotational speed of the servo motor 17 is decelerated in two stages, and the torque is increased twice, thereby driving the second planetary carrier 5 on the right side of the planetary gear mechanism to rotate. Since the second planetary carrier 5 on the right side of the planetary gear mechanism is the output on the right side of the planetary gear mechanism, And it is connected with the right side part 20 of the stabilizer bar through a spline. At this time, the power is transmitted to the right side part 20 of the stabilizer bar by the servo motor 17 through secondary deceleration and torque increase, and the right side part 20 of the stabilizer bar is connected with the load-bearing vehicle body. 19 is connected by a bush, so that the size of the roll angle of the load-bearing body 19 can be controlled.
行星齿轮机构左侧的动力传递和行星齿轮机构右侧的动力传递路径相同。The power transmission path on the left side of the planetary gear mechanism is the same as the power transmission path on the right side of the planetary gear mechanism.
本实施例中，主动横向稳定杆不同于被动横向稳定杆，本发明中，将横向稳定杆从中间断开，分为横向稳定杆左侧部分21和横向稳定杆右侧部分20两个部分，分别通过花键与行星齿轮机构左侧第二行星架13和行星齿轮机构右侧第二行星架5连接，横向稳定杆左侧部分21和横向稳定杆右侧部分20的前端均与悬架摆臂通过转动副连接，并且横向稳定杆左侧部分21和横向稳定杆右侧部分20的另一端分别与承载式车身19通过衬套连接，行星齿轮机构左侧第二齿圈18和行星齿轮机构右侧第二齿圈3均固定在承载式车身19上。In this embodiment, the active stabilizer bar is different from the passive stabilizer bar. In the present invention, the stabilizer bar is cut off from the middle and divided into two parts: the left part 21 of the stabilizer bar and the right part 20 of the stabilizer bar. They are respectively connected to the second planetary carrier 13 on the left side of the planetary gear mechanism and the second planetary carrier 5 on the right side of the planetary gear mechanism through splines. The arm is connected by a rotating pair, and the other ends of the left side part 21 of the stabilizer bar and the right side part 20 of the stabilizer bar are respectively connected with the load-carrying body 19 through bushings, and the second ring gear 18 on the left side of the planetary gear mechanism and the planetary gear mechanism The second ring gear 3 on the right is fixed on the load-bearing vehicle body 19 .
本实施例中，通过行星机构对伺服电机17的转速进行两次减速增扭，并且使得主动横向稳定杆左侧部分21和主动横向稳定杆右侧部分20扭转角度相等，扭转方向相反，从而达到了主动横向稳定杆的作用。In this embodiment, the rotational speed of the servo motor 17 is decelerated and increased twice through the planetary mechanism, and the left part 21 of the active stabilizer bar and the right part 20 of the active stabilizer bar are made to have equal torsion angles and opposite torsion directions, thereby achieving function of the active stabilizer bar.
具体工作过程分为两种路况：The specific working process is divided into two road conditions:
1）汽车做直线运动时，汽车车身只会在垂直方向上发生位移，这时，伺服电机17不工作，主动横向稳定杆的左侧部分21和主动横向稳定杆右侧部分20的作用分别和被动横向稳定杆的作用相同；1) When the car moves in a straight line, the car body will only be displaced in the vertical direction. At this time, the servo motor 17 does not work, and the functions of the left part 21 of the active stabilizer bar and the right part 20 of the active stabilizer bar are respectively Passive anti-stabilizer bars do the same;
2）汽车在做转向运动时，汽车车身在垂直方向上发生位移的同时，汽车车身还会发生侧倾运动，此时，汽车通过速度传感器、侧倾加速度传感器、侧倾角传感器和前轮转角传感器收集到的汽车的运动数据，通过控制算法得到伺服电机17工作的电流大小和工作的时间等参数，控制伺服电机17通过伺服电机输出端锥齿轮1驱动行星机构左侧第一齿圈11和右侧第一齿圈2转动。动力分为两路传递：一路为，伺服电机输出端锥齿轮1——行星齿轮机构右侧第一齿圈2——行星齿轮机构右侧第一行星齿轮8——行星机构右侧第一太阳轮9——行星齿轮机构右侧第二太阳轮6——行星齿轮机构右侧第二行星齿轮4——行星齿轮机构右侧第二行星架5——横向稳定杆右侧部分20；另一路为：伺服电机输出端锥齿轮1——行星齿轮机构左侧第一齿圈11——行星齿轮机构左侧第一行星齿轮16——行星机构左侧第一太阳轮10——行星齿轮机构左侧第二太阳轮14——行星齿轮机构左侧第二行星齿轮12——行星齿轮机构左侧第二行星架13——横向稳定杆左侧部分21。此时，横向稳定杆左侧部分21和横向稳定杆右侧部分20的抗侧倾力矩大小相等，方向相反，并且经过对伺服电机17的转速进行了两次减速增扭，足以在保证本发明机构较小的前提下满足工作要求。2) When the car is turning, the car body will be displaced in the vertical direction, and the car body will also be tilted. At this time, the car passes through the speed sensor, roll acceleration sensor, roll angle sensor and front wheel angle sensor. The collected motion data of the car is used to obtain parameters such as the current size and working time of the servo motor 17 through the control algorithm, and the servo motor 17 is controlled to drive the first ring gear 11 on the left side of the planetary mechanism through the bevel gear 1 at the output end of the servo motor. The side first ring gear 2 rotates. The power is transmitted in two ways: one way is, the bevel gear 1 at the output end of the servo motor—the first ring gear 2 on the right side of the planetary gear mechanism 2—the first planetary gear 8 on the right side of the planetary gear mechanism—the first sun on the right side of the planetary mechanism Wheel 9 - the second sun gear on the right side of the planetary gear mechanism 6 - the second planetary gear on the right side of the planetary gear mechanism 4 - the second planetary carrier on the right side of the planetary gear mechanism 5 - the right part of the stabilizer bar 20; Bevel gear 1 at the output end of the servo motor—the first ring gear 11 on the left side of the planetary gear mechanism—the first planetary gear 16 on the left side of the planetary gear mechanism—the first sun gear 10 on the left side of the planetary mechanism—the left side of the planetary gear mechanism Side second sun gear 14 —planetary gear mechanism left second planetary gear 12 —planetary gear mechanism left second planet carrier 13 —stabilizer bar left part 21 . At this time, the anti-rolling moments of the left part 21 of the stabilizer bar and the right part 20 of the stabilizer bar are equal in size and opposite in direction, and the rotational speed of the servo motor 17 has been decelerated twice to increase the torque, which is sufficient to ensure the Satisfy the job requirements under the premise that the invention organization is small.
