  • Patent number: 9914334
    Abstract: A motor vehicle rear structure includes an underframe component for supporting a motor vehicle floor, an axle component including a central part and two lateral parts that define, with the central part, a space to accommodate a component of the vehicle, and a pivot member including a first pivot element and a second pivot element which are able to pivot relative to one another. The rear structure is arranged such that the first and second pivot elements pivot relative to one another about an axis that is substantially horizontal and substantially perpendicular to a direction of travel of the vehicle in a frame of reference of the motor vehicle, when the first and second pivot elements are thus fixed to the central part of the axle component and to the underframe component of the motor vehicle, respectively.

  • Patent number: 9347483
    Abstract: A fall-off preventing structure of a propeller shaft does not allow a companion flange to be completely pulled off and dropped from a spline shaft when a nut loosens and comes off. In the propeller shaft, a round shaft part is provided on a front end of the spline shaft, a length of a threaded part of the spline shaft front end side on which the nut is screwed and the round shaft part is set longer than a length from a front end portion of the companion flange to a seat surface of the nut, and a total length of the length of the threaded part and the round shaft part and a length from the front end portion of the companion flange to the seat surface of the nut is set longer than the tolerable slide amount.

  • Patent number: 9238395
    Abstract: A rear wheel suspension including first and second suspension devices carrying a right and left, respectively, rear wheel rotating in a wheel plane forming a toe angle with respect to a longitudinal axis and a camber angle with respect to a vertical axis. A transversal beam connects the first and the second suspension device. Each suspension device includes a wheel spindle housing, defining a wheel center, and a leading link and a trailing link connected to the vehicle body. The transversal beam permits bending for vertical loads to provide the suspension devices a deflection to adjust the toe and camber angles such that the changes of the camber angles when the wheel planes converge towards an upper point above the wheel center connect to a controlled adjustment of the toe angles such that the wheel planes converge directionally towards a rear point located rearwards of the wheel center.

  • Patent number: 7938221
    Abstract: A suspension system for a vehicle includes a swing frame and right and left suspension cylinders for front wheels. The swing frame is swingably supported by the front portion of a vehicle body about a support shaft extending in a lateral direction, and supports the front axle case, so as to allow the front axle case to swing about a center shaft extending in a front-rear direction. The right and left suspension cylinders are provided on the swing frame. A lateral oscillation regulation unit is provided between the swing frame and the front frame, and configured to regulate an oscillation of the swing frame by contact in the lateral direction.

  • Patent number: 6929084
    Abstract: A suspension module for use with an independent suspension system includes a subframe having a pair of subframe rails and a bridge supported therebetween. A pair of semi-trailing arms are pivotally attached to the subframe rails. Each semi-trailing arm includes an airbag support onto which an airbag is mounted. The airbags are positioned between the airbag supports and the subframe rails. A shock absorber extends from the semi-trailing arms to the subframe rails. A drive line brings rotational drive from a transmission to a carrier housing attached to the bridge of the subframe. A carden shaft extends from the carrier housing to spindles attached to the semi-trailing arms to transmit rotational drive from the carrier housing to the spindles.

  • Patent number: 6267197
    Abstract: An axle shaft spacer member for use with a suspension lift kit. The spacer member enables the wheel spindle of a vehicle to be moved laterally a desired distance, which in turn enables the upper control arms associated with the wheel spindle to be lowered when such would not otherwise be possible because of interference with the frame portion of the vehicle. The spacer is a disc-like member having a thickness equal to the desired lateral offset distance needed to enable the upper control arm to be lowered and re-mounted via a drop bracket, to the frame. The spacer member enables the original suspension geometry to be maintained, thus maintaining the ride and steering characteristics of the original suspension system while enabling vehicle ride height to be increased.

  • Patent number: 5433287
    Abstract: A driven axle assembly for a vehicle includes a center housing, suspension elements connecting the center housing to the vehicle, a main drive arranged in the center housing, side drives arranged on outer ends of the center housing, and wheel hub units connected to the side drives, respectively,, wherein a portal distance is provided between a longitudinal axis of a differential gear unit arranged in the center housing and a longitudinal axis of the wheel heads. The improvement achieved by this invention is that the suspension elements connecting the center housing to the vehicle are also attached to the housings for the drives arranged both inside and on outer ends of the center housing in an integrated manner. Therefore, the housings for the side drives, the center housing, and the suspension elements are formed as a tight compact unit.
