A wind noise reduction apparatus for a motor vehicle includes a mirror housing, a mirror held in the mirror housing and a control module. That control module is configured to displace the mirror housing to reduce wind noise while simultaneously displacing the mirror to maintain a constant visual field.

A vehicle, a prop-shaft and a method of reducing noise in a vehicle are provided. The prop-shaft includes a cylindrical shaft having a hollow interior. A liner is positioned within at least a portion of the hollow interior. A first retaining member is disposed adjacent an end of the liner, the first retaining member sized to inhibit movement of the liner in a first direction. A second retaining member is disposed adjacent an opposite end of the liner from the first retaining member, the second retaining member sized to inhibit movement of the liner in a second direction, the second direction being opposite the first direction.

This invention concerns a damper used to reduce the running noise of track wheels. It can absorb wheel vibration, reduce oscillation amplitude and reduce the noise radiation of the wheel. The damper has a damping connector and a damping ring which has an open section; the end of the open section has an angled plane; the damping connector has a pipe-shaped object with two locating objects at the both ends; the locating object has a bar which can get into the pipe-shaped object and a wedge-shaped object which matches the angled plane of the end of the open section; inside the pipe-shaped object is a spring which can push out the two locating objects; each locating object has a locating hole which allows a bar to get through from the pipe-shaped object.

A control device controls a four-wheel drive vehicle including an engine, a torque transmission mechanism which transmits an output torque of the engine to main drive wheels and to auxiliary drive wheels, and a torque distribution adjustment mechanism provided in the torque transmission mechanism and configured to adjust torque distribution with respect to the auxiliary drive wheels. The control device is provided with an abnormal noise reduction unit which controls the torque distribution adjustment mechanism to adjust torque distribution with respect to the auxiliary drive wheels in such a manner as to suppress abnormal noise generation when the engine is operated in an abnormal noise generation range in which the torque transmission mechanism is in an abnormal noise generation state. The abnormal noise reduction unit adjusts the torque distribution with respect to the auxiliary drive wheels in accordance with a magnitude of torque fluctuation of the engine.

A vehicle includes a three-axis accelerometer attached to a door and in communication with a processor. A speaker is in communication with the processor. Operation of the door toward a closed position is measured by the accelerometer to define a corresponding door acceleration. The processor determines a corresponding door-operating event based on the corresponding door acceleration and the speaker delivers a corresponding audio signal in response to the corresponding door-operating event.

A power transmission structure of a vehicle, which is provided with a first rotor, a second rotor, and a metallic cylinder. In this power transmission structure, the reduction shaft and the second rotor shaft receive reaction force from the cylindrical metallic member in radially opposite directions. The cylindrical metallic member is deformable elastically in a radial direction and press-fitted in a part where the reduction shaft and the second rotor shaft of a second electric motor overlap each other in the radial direction adjacent to a spline fitting part of the reduction shaft and the second rotor shaft. Therefore, misalignment between the axis of the reduction shaft and the axis of the second rotor shaft is restrained, and generation of tooth hitting sound is thus restrained. Since the cylindrical metallic member has high rigidity and is restrained from being deformed in a rotation direction, responsiveness of torque transmission is improved.

A tolerance ring is arranged between an output-side rotary shaft and a rotor shaft. For this reason, even when looseness in a spline fitting portion of the output-side rotary shaft and rotor shaft is not filled, both the output-side rotary shaft and the rotor shaft are held by the tolerance ring so as not to rattle. Therefore, it is possible to reduce tooth hammer noise that occurs in the spline fitting portion.

A guide sleeve, for receiving a rod of a headrest, includes a sleeve body that has a rod receptacle for receiving the rod and an elastic region that is force-loaded in a direction of the rod receptacle in order to fix the rod in the rod receptacle. A spring element arranged on the outer contour of the sleeve body spring-loaded the elastic region. The spring element has a contact region adjacent to the elastic region, is configured as a clip that partially embraces the sleeve body and has a width in a sleeve body axial direction. The spring element includes a strip main body and the contact region is configured as a protuberance between two first bending points extending across the entire width of the main body. A vehicle seat for a motor vehicle has a backrest and a headrest, wherein the guide sleeve fastens the headrest to the backrest.

An outer mirror for a vehicle according to the technology of the present disclosure includes a mirror stay, a mirror visor, and a mirror for checking behind the vehicle. The mirror stay is provided at a vehicle body side face. The mirror visor is supported by the mirror stay and includes an opening portion at a vehicle rear side. The mirror is provided in the opening portion. In a horizontal section cut through the mirror visor, a distance between a vehicle width direction inner side face of the mirror visor and the vehicle body side face decreases toward the vehicle rear from a front end portion of the mirror visor.

A removable panel system for easily and efficiently varying the configuration of a cabin on a vehicle. The removable panel system generally includes a vehicle having a cab defined by a frame. Different panels may be selectively and removably connected to the frame to form various different cab configurations to suit the different needs of different jobs or operators. A roof panel may be removably connected to the frame to form a roof of the cab. A rear window extension may extend from the roof panel to form the rear window of the cab. A door receiver panel and/or door panel may be removably connected to the frame to form one or more doors of the cab. A windshield panel may be removably connected to the frame to form a windshield for the cab. All panels are adapted to be easily and efficiently interchanged without undue effort from the operator.
