摘要:
A sensor for measuring the difference between the velocity and/or position of a vibration-suppressing cylinder and that of a piston connected to a piston rod and moving back and forth inside the cylinder in a dashpot for motor vehicles. The sensor consists of a permanent magnet and of a winding in the form of a cylindrical coil and operating in conjunction with the magnet. The magnet is connected directly or indirectly to one of the mutually moving components and the winding is connected directly or indirectly to the other. The component that the magnet (5) rests against and the component that the winding (7) rests against constitute a complete circuit that carries the magnet's field.

A relative velocity sensor in a vehicle suspension damper comprises an annular, radially polarized magnet at the top of the shock cylinder adjacent a sensor winding on the inside of the dust tube. A closed magnetic circuit is defined from the magnet through an annular magnetic member inside the magnet to the piston rod and back through the dust tube across the sensor winding to the magnet. Flux below the magnet is similarly confined through the cylinder and does not affect the sensor winding. The air gaps at the winding and the piston rod do not change with axial movement; and the flux linkage variation with axial movement is thus linear across the entire coil. A voltage is generated across the coil which is a strong and accurate signal of relative movement between the sprung and unsprung masses of the vehicle.

A suspension assembly between a sprung element and an unsprung element includes a load-carrying spring element arranged in parallel with a negative stiffness element between the sprung element and the unsprung element. The negative stiffness element includes first and second opposed mutually-repelling elements.

A linear actuator includes a first tube, a second tube inserted into the first tube to be free to slide, a rod fixed at one end of the rod to the first tube, a rod guide provided on the other end of the rod so as to slide relative to the second tube, a plurality of permanent magnets held by the rod, a holder that is fitted into the second tube and holds a plurality of coils, a first chamber defined between one end of the holder and an end portion of the first tube, and a second chamber defined between the other end of the holder and the rod guide. An insertion hole which connects the first chamber to the second chamber and through which the rod passes is formed in the holder. A connecting groove that connects the first chamber to the second chamber is formed in the second tube to extend in an axial direction.

A suspension system and a method for controlling a suspension system for a muscle-powered two-wheeled vehicle having a damper device with a first damper chamber and a second damper chamber coupled with one another via a controllable damping valve. A sensor is provided for capturing data about a current operational state. An electric control device and a data storage device for controlling the damper device are provided, such that at least one damping characteristic of the damper device can be influenced by a signal from the control device. The control device is configured and organized to provide a teaching mode in which route-related data are stored in the memory. The control device is furthermore configured and organized to provide a repeat mode in which the damper device is controlled according to the route-related data stored in the memory device.

摘要:
A pressure control valve unit to be employed in an active suspension system includes a valve member movable between a pressure increasing mode position, a pressure decreasing mode position and a pressure holding mode position for adjusting fluid pressure in a working chamber of an active cylinder disposed between a vehicular body and a suspension member rotatably supporting a road wheel. The valve member is further movable to a pressure relieving position in response to a pressure in the working chamber higher than a predetermined value. The valve member at the pressure relieving position establishes fluid communication between the working chamber and a drain line for draining pressurized fluid in the working chamber at a draining rate higher than that in said pressure decreasing mode position.

Provided is a hybrid electromagnetic suspension capable of self-powering and a control method thereof. The hybrid electromagnetic suspension includes an integrated structure of linear motor and cylinder block of equivalent hydraulic damper, a suspension spring, a connecting pipeline, a hydraulic rectifier bridge, an accumulator, a hydraulic motor and a rotary motor. The upper and lower chambers of the working cylinder, the lower chamber of working cylinder and oil storage cylinder are connected through the hydraulic rectifier bridge and the pipeline. The control has three modes including passive mode, semi-active mode and active mode. The ECU detects the road level according to the received sensor signal, and switches to the corresponding mode to control the suspension according to obtained road level, so as to obtain the optimal suspension performance under each road level. In the device of the invention, the linear motor and the equivalent hydraulic damper recover the vibration energy together in the case of good road condition; the linear motor and the equivalent hydraulic damper attenuate the suspension vibration together in the case of poor road surface, and at the same time the equivalent hydraulic damper also recovers the vibration energy, thus the self-powering can be realized.
