摘要： A rear wheel steering system is disposed in a rear wheel steering mechanism and has a power cylinder for generating a power for steering the rear wheels in response to a liquid pressure. The power cylinder is connected to a pump as a source of generating the liquid pressure through a high pressure passage and further to a reservoir tank through a low pressure passage. The high pressure passage is connected to the low pressure passage through a relief passage on the pump side and a relief passage on the power cylinder side, the relief passages being disposed in parallel to each other. The rear wheel steering system is provided with a passage shifting system for closing the relief passages during stationary period of time while opening each of the relief passages during operation and dividing the high pressure passage between the relief passages into sections and with a narrowed passage portion disposed at the relief passage on the power cylinder side. Operation of the passage shifting system independently allows the high pressure passage on the pump side and the high pressure passage on the power cylinder side to be communicated with the low pressure passage. At this time, the liquid pressure from the power cylinder is gradually released by the action of the narrowed passage portion. The liquid pressure withdrawn from the pump is rapidly released to the low pressure passage without interference with the narrowed passage portion.

摘要： A vehicle suspension system has fluid cylinders connected between the vehicle body and the respective wheels. A fluid control system controls feed and discharge of hydraulic fluid to and from the fluid cylinders and changes the suspension properties of the suspension system. A failure in the fluid control system is detected and when the control system fails, one of first to third measure modes is taken on the basis of the kind of the failure. Warning is just given and the control of feed and discharge of hydraulic fluid to and from the fluid cylinders being continued when the first measure mode is taken, the control of feed and discharge of hydraulic fluid to and from the fluid cylinders is interrupted with the chassis height fixed to the present height when the second measure mode is taken, and the fluid in the fluid cylinders is discharged and the chassis height is lowered when the third measure mode is taken.

摘要： A four-wheel-steered vehicle is provided with a front wheel turning mechanism and a rear wheel turning mechanism which respectively turn front and rear wheels in response to the rotation of a steering wheel. The rear wheels are turned in the same direction as the front wheels when the steering wheel is turned while the vehicle is in a predetermined operating condition. A rear suspension system which supports a rear wheel has a wheel support which supports a rear wheel and is connected to a rear wheel turning rod of the rear wheel turning mechanism so that the rear wheel on the wheel support is turned about a king pin axis when the rear wheel turning rod member is displaced. Upper and lower arms are connected to the wheel support and guide the wheel support so that the rear wheel on the wheel support is turned about the king pin axis in response to displacement of the rear wheel turning rod. A coil spring is connected between the wheel support and the vehicle body and restrains vertical motion of the wheel support under the counterforce thereof, the coil spring being arranged so that the line of action of the counterforce is tilted with respect to the king pin axis so that it is not parallel to the king pin axis, does not intersect the king pin axis and is directed such that the counter force turns the wheel support in the toe-out direction of the rear wheel thereon.

摘要： A wheel support rotatably supports a dirigible wheel. An upper wheel-support support member connects an upper portion of the wheel support to the vehicle body, and a lower wheel-support support member connects a lower portion of the wheel support to the vehicle body. The upper and lower wheel-support support members are arranged to respectively define upper and lower pivot points which define an imaginary kingpin axis. At least one of the upper and lower wheel-support support members is formed of a pair of separate link members one end of each of which is pivoted on the vehicle body at different portions of the vehicle body and the other end of each of which is rotatably connected to the wheel support at different portions of the wheel support. The upper and lower wheel-support support members are arranged so that the upper portion of the wheel support is displaced more inward than the lower portion thereof when the wheel makes a turn as the outer wheel, and so that the upper portion of the wheel support is displaced less inward than than the lowr portion thereof when the wheel makes a turn as the inner wheel.
