Clutch apparatus, systems, and related methods for use with vehicle stabilizer bars are disclosed. A disclosed stabilizer bar disconnect system includes a fluidic clutch configured to control torque transferred between first and second bar members during a driving event to control a roll stiffness of a vehicle. The fluidic clutch includes: a housing, a fluid chamber in the housing; a fluid reservoir in fluid communication with the fluid chamber; first and second fluid control members in the fluid chamber and connected to the first and second bar members, and fluid valves configured to control a flow of a fluid through the fluid chamber and the fluid reservoir. The fluidic clutch is changeable between a connected state in which the fluidic clutch couples the first bar member to the second bar member and a disconnected state in which the fluidic clutch decouples the first bar member from the second bar member.

An adjustable anti-roll bar arrangement for a vehicle, comprising a bracket configured to be mounted in a fixed relationship to a chassis or a an axle of the vehicle, a linear actuator connected to the bracket, a guided element, the linear actuator being configured to drive the guided element along a first geometrical axis, a supporting shaft mounted to the bracket and defining a second geometrical axis which has a different extension compared to the first geometrical axis, an anti-roll bar, and a stabilizer stay having a first end connected to the anti-roll bar, and a second end movably connected to and supported by the supporting shaft, the second end being also connected to the guided element such that when the linear actuator drives the guided element along the first geometrical axis, the second end follows the motion along the second geometrical axis. The invention also relates to a vehicle comprising such an arrangement.

In each of a first stabilizer device and a second stabilizer device, a stabilizer bar is supported by one or more cylinders, a communication passage via which two fluid chambers of each cylinder are connected is provided, and an opening-closing valve is disposed in the communication passage such that an inter-fluid-chamber communication state where the two fluid chambers communicate with each other and an inter-fluid-chamber shutoff state where the two fluid chambers are shut off from each other are selectively established. Hereby, a vehicle body roll restraining effect is achieved in the inter-fluid-chamber shutoff state while the vehicle body roll restraining effect is cancelled in the inter-fluid-chamber communication state. A linkage mechanism by which those two states of each of the stabilizer devices are changed in conjunction with each other is provided.

In a stabilizer device, a stabilizer bar having both ends connected to right and left wheel holding portions is supported at a pair of right and left supported portions of the stabilizer bar by a vehicle body via a pair of cylinders that can be extended and retracted based on vertical movement of wheels. The stabilizer device includes two communication passages, each of which allows one of two liquid chambers of one of the pair of cylinders and the other of two liquid chambers of the other cylinder to communicate with each other. The stabilizer device further includes an inter-passage communication passage that allows the two communication passages to communicate with each other, and an on-off valve that is opened and closed to open and close the inter-passage communication passage.

A method for manufacturing a hollow spring member having a hollow steel spring rod having terminal sealed portions at both ends thereof. Each terminal sealed portion has a rotationally symmetric shape in which an axis passing through a center of the spring rod is an axis of symmetry. Each terminal sealed portion has an end wall portion including an end face; an arc-shaped smoothly curved surface between an outer peripheral surface of the spring rod and the end face, and a hermetically closed distal-end-center closure portion on the axis passing through the center of the spring rod. The method includes forming each of the end portions of the spring rod by forming a chamfered portion on an inner or outer peripheral side of the end portion of a hollow wire, the end portion having an opening portion at a distal end, heating the end portion of the hollow wire having the chamfered portion, and spinning the heated end portion to be gathered toward the axis from the outer peripheral side by a jig. The end wall portion, which includes the distal-end-center closure portion, is formed by the distal end of the end portion being joined together on the axis.
