差支えない０[Minor oscillation of the wheel (called shimmy) transmitted from the wheel side to the handlebar side due to <m'! In order to suppress negative vibrations (called kickbanks), a fluid-filled cylinder equipped with a piston that interlocks with the rack and sleeve is installed, and the cylinder divided by the piston is used as a communication passage connecting the two chambers. A damper device is known (for example, Japanese Patent Publication No. 45-9404), which is provided on the piston and is formed to absorb shimmy, kinkback, etc. by the flow resistance of fluid in the cylinder. However, while increasing the number of damper devices described above absorbs vibrations, it also adds a certain flow resistance due to the fluid, which inevitably reduces the performance of returning the steering wheel to the straight position. (Recently, the return performance has tended to deteriorate.) - When steering the wheel at a large angle or when driving at low speeds, it is necessary to improve the return performance even though there may be a slight decrease in vibration absorption performance. Performance that changes in response to the driving and steering conditions of the vehicle is now required, such as the need for further improved vibration absorption performance when driving on roads or at high speeds. ing. (Problems to be Solved by the Invention) This invention solves the above-mentioned problems of conventional damper devices, and absorbs minute shimmies and severe jerks in response to vehicle running and steering conditions. , and no.
To provide a damper device for a rack and pinion type steering, which causes less deterioration in return performance of the steering wheel. (c) Means for Solving Problems) In order to solve the above problems, the present invention provides a rack and pinion type steering system for a vehicle in which wheels are steered by direct motion of a rack shaft, and a piston that interlocks with the rack shaft. In the damper device, the damper device is provided with a cylinder having a cylinder and a communication path that communicates two chambers of the cylinder divided by the piston, in which an electromagnetic adjustment means is arranged in the communication path to adjust the flow rate of the fluid by electromagnetic force. a sensor means that detects a physical quantity that changes depending on the running and steering state of the vehicle and generates an electric signal; and a control device that calculates an input signal from the sensor means and generates a signal that controls the operation of the electromagnetic adjustment means. This damper device for a rack-binion type steering is characterized in that it is formed so that the damper effect changes in response to changes in the physical quantity. (Function) Next, the function of the damper device of the present invention will be explained. In response to physical changes caused by driving and steering conditions such as high-speed driving, large-angle steering, sudden changes in vehicle speed, and acceleration of vertical movement of the vehicle, vibration absorption and steering are possible. In order to control the two performances, which have contradictory tendencies, such as improving the return performance, to the state most suitable for the vehicle according to the driving situation in response to the changing physical quantities, the physical quantities are detected and an electrical signal is generated. and a control table (iii) that calculates the input signal from the sensor means and determines the optimum conditions, and operates the electromagnetic adjustment means disposed in the communication path of the cylinder having the piston that interlocks with the rack shaft. At least, the area through which the fluid flows in the flow path of the communicating path is adjusted, and the damper effect is changed in accordance with the change in the object Jll!:iiii. (Example) Next, according to the present invention Examples of damper devices for rack and pinion steering are shown in ``Xta'' and Figures 2 to 7.
FIG. 1, which will be explained with reference to the diagrams shown up to the figures, is a cross-sectional view of the lower part of an embodiment of a damper device for a rack and pinion type steering according to the present invention.

1f magnetic coil, 10 is a vehicle speed sensor, 11 is a steering angle sensor, 12 is an acceleration sensor for the rack axis, ] 3 is an acceleration sensor for the vertical movement of the vehicle body, 1 and 1 are torque sensors for the steering wheel axis, and 15 is a control device. . First, let us explain about Figure 1. The figure shows an implementation example of a damper device for a rack and pinion type steering according to the present invention.
11, the piston 3 is mounted on the rack shaft 20 which engages with a pinion (not shown) and moves directly through the input %RL steering (IC) which is directly connected to the handle shaft. A cylinder 4 filled with fluid is provided.
A regulating valve having an regulating member 8 having an regulating part 81 having a tapered end at a position connecting the communication passages 5 and 6 which communicate two chambers in the cylinder divided by the piston 3. A member 7 is disposed, and the other end of the adjusting member 8 is held within an electromagnetic coil 9, and the electromagnetic coil 9 is adjusted in response to a change in the current that excites the electromagnetic coil 9.
The adjusting portion 81 moves the adjusting valve member 7 in the axial direction.
The adjustment hole 71 is formed so as to change the flow rate of the fluid by adjusting the area of the fluid flow path of the adjustment hole 71 that communicates with the communication path 5 provided therein. On the other hand, a vehicle speed sensor l0 is used as a sensor means for electrically detecting a physical quantity that changes depending on the running steering state of the vehicle.
1) Handle IIAII (directly connected to input 11111) Steering angle sensor 11, acceleration sensor 12 for rack shaft 2 movement, acceleration sensor 12 for vertical movement of the vehicle body] 3, high river wave component sensor 14 for steering wheel shaft torque, respectively. The electrical signals corresponding to the respective detected physical quantities are input to the control device 15. The control device 15 calculates input signals from each of the sensors based on preset standards, determines optimum conditions for the vehicle, and applies excitation current to the electromagnetic coil 9 to control the electromagnetic coil 9.
By changing the axial position of the adjusting member 8 in the electromagnetic coil 9, the area of the flow path of the adjusting hole 71 of the 'fA valve regulating member 7 is adjusted to change the flow rate of the fluid, thereby producing a damper effect. It is designed to change. Figure 2 is a chart showing the relationship between the steering angle of the handle shaft and the adjustment area of the flow passage of the adjustment hole of the communication passage.When the steering angle exceeds a predetermined value, the area of the flow passage increases, and the damper effect is reduced. The aim is to improve the ability of the handlebar to return even if it is slightly dropped. Figure 3 is a chart showing the relationship between the change in the flow path area of the adjustment hole and the acceleration of the rack shaft movement.As the acceleration of the rack shaft movement increases, the flow path area is reduced up to a certain value, and the damper This shows that the effect is increasing. Figure 4 shows the relationship between the vehicle speed and the flow path area of the adjustment hole, and shows that as the vehicle speed increases, the flow path area is reduced, increasing the damper effect and aiming to absorb minute shimmy. ing. Figure 5 shows the relationship between the change in the flow path area of the adjustment hole and the acceleration of the vertical movement of the car body.As the acceleration of the vertical movement of the car body increases, the area of the flow path is reduced and the damper effect increases. It shows that it is like this. Figure 6 shows the high-frequency component of the input shaft torque due to the kick bank transmitted from the wheel side (this is the minute fluctuation of the reverse operation torque fluctuation of the input shaft due to the kick pack, and the difference from the input shaft steering torque due to human power). This figure shows the relationship between the change in the flow path area of the adjustment hole (distinguished by the same wave number) and the change in the flow path area of the adjustment hole. * indicates that it is formed to shrink. FIG. 7 shows how the damper effect changes in response to changes in the flow path area of the adjustment hole, and shows that the damper effect changes while decreasing as the flow path area increases. (Effects of the Invention) A damper device for a rack and pinion type steering according to the present invention is provided with a cylinder filled with fluid and equipped with a piston interlocking with a rack shaft, and a communication path that communicates two chambers divided by the piston. In the operation, an electromagnetic adjustment means having an adjustment member for adjusting the fluid flow Pit is disposed in the communication path, and a sensor means for detecting a physical quantity that changes depending on the running and steering conditions of the vehicle and emitting an electric signal, and the sensor means A 1" 3-control device is installed to emit a signal to control the operation of the electromagnetic means by adding up the input signal from the input signal, and the damper effect is changed in response to changes in physical quantities. When you want to increase the damper effect, such as when there is a kickback caused by driving, vertical movement, sudden changes in vehicle speed, or minute shimmy, or conversely, when you want to reduce the damper effect to some extent, such as when the steering angle is large. In response to two conflicting demands, such as when aiming to improve steering wheel return performance, the damper effect can be controlled while determining the optimal thread condition for the vehicle in that situation, so it is always possible to In this embodiment, the physical quantities detected by the sensor means and used to control the damper effect include vehicle speed, steering angle of the steering wheel shaft, interlocking acceleration of the rack shaft, and vehicle body. The high-frequency components of the acceleration of the upward and downward movements and the torque of the handle shaft are taken, but instead of detecting all of these physical quantities, one or more elements are detected and output to control the damper effect. There is no problem with 0
