A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

Provided are: a linear-motion damper which can avoid an increase in the size of a device configuration of an attachment target and broaden the type of attachment target to which the linear-motion damper is attachable; and a steering device including the linear-motion damper. A steering device (100) includes a linear-motion damper (120) between a rack bar (103) and a rack end (106). In the linear-motion damper (120), an inner chamber (121) is formed between an inner chamber forming body (130) and a socket main body (107) therein. The socket main body (107) is a shaft-shaped component forming the rack end (106) in the steering device (100). The socket main body (107) is slidably fitted in the inner chamber forming body (130). The inner chamber forming body (130) is formed in a tubular shape, and at an inner peripheral portion thereof, is formed with a circular ring-shaped flow control valve (140). The flow control valve (140) includes a first flow control valve (150), a second flow control valve (160), and a third flow control valve (170).

This invention provides a vehicle steering wheel vibration reducing structure capable of effectively damping induced vibration generated in the steering wheel and contributing to vibration reduction in both low frequency bands and high frequency bands.

A vehicle steering wheel vibration reducing structure, where the vehicle steering wheel structure is such that an airbag module-2, which serves as a damper mass, is attached to the steering wheel via vibration damping parts 19 to damp vibrations of the steering wheel, and where the airbag module is formed such that the upper region above the center of steering of the steering wheel is lighter than the lower region, with reference to a neutral position of the steering wheel.

A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

The invention relates to a vibration absorber ring (10) for fastening a gas generator (12) to a vehicle steering wheel (14), in a manner capable of vibrating, with a ring axis (A), a support portion (18) for fastening the vibration absorber ring (10) to a holding element, and an absorber portion (22) for fastening the gas generator (16) to the vibration absorber ring (10), wherein an elastic damping element (24) is provided, which extends in the axial direction from the absorber portion (22) towards a free end (26) and, between the absorber portion (22) and the free end (26), has a fastening element (28) for the gas generator (12), wherein the support portion (18) and the absorber portion (22) are spaced apart from each other in the axial direction.

A vehicle active vibration control (AVC) system includes a vehicle having at least an engine, a transmission, a controller area network (CAN) bus, a frame, and a cabin. The vibration control devices (120) are distributed about the frame, with each device including a circular force generator (CFG) (122). At least one sensor is positioned on the frame to detect and measure a noise and/or vibration within the cabin. Each sensor creates an electronic data signal and electrically communicates with a corresponding vibration control device. Each vibration control device receives an electronic data signal from a corresponding sensor and vehicle data from the CAN bus. Each vibration control device processes the electronic data signal and the vehicle data. The CFG of each vibration control device generates a vibration canceling force having a magnitude and phase that attenuates noise and/or vibration within the cabin.
