摘要： In a steering damper utilizing hydraulic pressure, even if generation of a damping force is controlled in correspondence with an external force inputted to a handle upon external perturbations and the like, the damping force changes due to change in liquid temperature of working liquid. Accordingly, to precisely control the damping force, correction based on change in liquid temperature of the working liquid is required. However, to measure the change in liquid temperature of the working liquid, it is necessary to provide a particular measurement device requiring a complicated structure, which increases the number of parts and costs. Accordingly, the present invention has an object to provide a steering damper which can easily temperature-correct the damping force without such difficulty. A liquid chamber is provided in a main body of a steering damper. An inside of the liquid chamber is partitioned into a right liquid chamber and a left liquid chamber by a rotatable partition wall integral with a shaft coaxial with a steering shaft. Both liquid chambers are connected with each other by a liquid passage, and a control valve is provided in the middle of the passage such that the damping force is variable. A control device drive-controls the control valve in correspondence with a turning angle speed of the shaft and the partition wall, thereby controls the damping force, and corrects the damping force based on intake temperature information detected by an intake temperature sensor.
摘要翻译： 在使用液压的转向阻尼器中，即使在外部扰动等输入到手柄中的外力相应地控制阻尼力的产生时，阻尼力由于工作液体的液体温度的变化而变化。 因此，为了精确地控制阻尼力，需要基于工作液体的液温变化的校正。 然而，为了测量工作液体的液体温度的变化，需要提供一种需要复杂结构的特定测量装置，这增加了部件数量和成本。 因此，本发明的目的是提供一种能够容易地对阻尼力进行温度校正而没有困难的转向阻尼器。 在转向阻尼器的主体中设置有液体室。 液体室的内部通过与转向轴同轴的轴一体的可旋转分隔壁分隔成右液室和左液室。 两个液体室通过液体通道彼此连接，并且控制阀设置在通道的中间，使得阻尼力是可变的。 控制装置根据轴和分隔壁的转角速度驱动控制控制阀，从而控制阻尼力，并根据由进气温度传感器检测到的进气温度信息来校正阻尼力。

摘要： A steering damper device attenuating the oscillations of the handlebar of a motorcycle during operation, and more particularly, a device capable of varying a damping force variable. The steering damping device prevents the adverse effect of oscillations of the handlebar that would otherwise occur when the load on the front wheel of the motorcycle becomes light. The device includes a rotary steering damper provided in a coaxial manner on a steering shaft. Either a damping force or zero damping force is produced by a variable valve arranged in the bypass passage communicating with a right liquid chamber and a left liquid chamber. The variable valve is controlled by a control device and generates a damping force in the steering damper only when the acceleration of the motorcycle as detected by the acceleration sensor exceeds a threshold value.

摘要： If a steering damper is fixed to a top bridge, since the steering damper is comparatively heavy and the top bridge is on the steering side, steering inertia increases. An arrangement structure of the steering damper which does not greatly influence the steering inertia has been realized. A rotatable partition wall is provided in a hydraulic chamber of a steering damper to partition the inside into a right hydraulic chamber and a left hydraulic chamber. Both hydraulic chambers are in communication with each other by a liquid passage. A control valve is provided in an intermediate part of the passage and is switched to a lock or a throttle thereby a damping force zero status or a damping force generation status is set.

摘要： A steering damper for reducing the inertia of steering that is attached in a low position relative to the steering shaft. The upper portion of a steering shaft is fitted in the center of the rear of a top bridge as a fitting part and a lower screw part of a shaft is tightened in the fitting part and is integrated with the fitting part. The shaft is provided with a shaft main part having a small diameter extending in an axial direction of the steering shaft, when the shaft main part is made to pierce a turning shaft in the steering damper. A steering nut is attached to an upper screw part at the upper end and the upper screw part is tightened. The steering damper and the top bridge are fixed to the upper portion of the steering shaft by jointly fastening. Hereby, a steering nut heretofore provided under the steering damper can be omitted and a position in which the steering damper is attached can be lowered by the quantity. A rear portion of the liquid-operated steering damper is designed to fit into a space in the fuel tank so that it does not interfere with the front end of a fuel tank. The steering damper does not interfere with the capacity of the fuel tank.

摘要： To generate a damping force in a steering damper only upon an unintentionally caused handle action when it is truly necessary to restrain the turning of the handle, according to whether the cause of a handle action is intentional or unintentional. A rotation type steering damper is provided coaxially with a steering shaft, and the generation of a damping force or zero damping force is selected through a changeover by a variable valve provided in a bypass passage for communication between a right liquid chamber and a left liquid chamber of the steering damper. The changeover is controlled by a control device, which functions based on the direction of a moment exerted on the steering shaft detected by a moment sensor and the magnitude and direction of a rotational angular velocity concerning the turning of the steering shaft detected by a rotational angular velocity sensor, for controlling a damping force that is generated only when an unintentionally caused handle turning action opposite in direction to the moment is present and the rotational angular velocity has exceeded a predetermined threshold value.

摘要： A liquid pressure type steering damper system for generating a damping force for preventing a handle from being swung due to a kick-back upon a disturbance wherein the generation of the damping force is nonlinear so that the steering angle would not be enlarged so much even if the kick-back becomes greater. A liquid pressure type steering damper is provided with a restriction passage for a working liquid and a solenoid-type control valve for varying the passage sectional area of the restriction passage. A needle portion is formed at the tip end of a plunger constituting the solenoid valve and is made to advance and retract in a restriction portion connected to a bypass passage. An annular gap passage is formed between the needle portion and the inside wall of the restriction portion so that, when the needle portion advances or retracts in proportion to the steering speed of a front wheel steering system, the clearance area of the gap passage is varied in the manner of a quadric curve in relation to the stroke amount of the needle portion, whereby the generation of the damping force is rapidly increased in the manner of a quadric curve. In addition, an upper limit of the damping force is restricted by an electromagnetic force of the solenoid valve.

摘要： To make steerability more satisfactory in conformity with actual operation, by correcting the regulation of a damping force based on a variable quantity which has a close relationship with the magnitude of kick-back and with which the steering conditions at the time of actual operation can be grasped appropriately, in contrast to the system in which the regulation of the damping force is controlled linearly in proportion to a variable quantity related to the magnitude of kick-back. In a steering damper system of the liquid pressure type in which a damping force is exerted on a front wheel steering system provided at a front portion of a vehicle body and which comprises a control valve for making the damping force variable, the damping force is controlled based on the steering speed.

摘要： A partitioning member for dividing a connecting pipe into at least two exhaust passageways is provided in the connecting pipe, which is attached to an exhaust side of a silencer. A valve mechanism is operable to vary the passageway area of one of the exhaust passageways. With this structure, for example, when an engine is rotating at low revs, exhaust gas is discharged from the exhaust passageway without the valve mechanism, while when the engine is rotating at high revs exhaust gas is simultaneously discharged from the exhaust passageway having no valve mechanism and a passageway provided with the valve mechanism. Therefore, it is possible to reduce exhaust noise when the engine is rotating at low revs.
