A driving robot device is provided. The driving robot device may include a plurality of suspensions configured to absorb a shock applied by a driving surface on which the driving robot device drives; a first driving part that includes a motor and is configured to adjust a strength of the plurality of suspensions; and at least one processor configured to control the first driving part to adjust the strength of the plurality of suspensions based on driving surface information with respect to a state of driving surface, and based on food information with respect to a state of food carried by the driving robot device.

A wheel carrier assembly for a front axle or rear axle of a motor vehicle, with a wheel carrier part on which a link for a control arm assembly, a fixing device for a damper strut and a recess for a wheel bearing are provided. The wheel carrier part includes an air guide device for supplying air to a disk brake assembly, which as brake parts has at least a brake disk and a brake caliper. The wheel carrier part has a circumferentially hollow wheel carrier housing part. The air guide device includes at least one air inlet opening and at least one air outlet opening directed onto a brake part.

A fabricated torque arm for use in a vehicle suspension, including a rod having a solid rectangular cross-section, the rod having a first end and an oppositely disposed second end, a first bushing hub, and wherein the rod is only a single piece cut from a metal plate or sheet, wherein the first bushing hub comprises cut tubing, wherein the first end of the rod has a radius that conforms to an outer surface of the first bushing hub, and wherein the first end of the rod is welded to the outer surface of the first bushing hub.

A ball joint press for installation/removal of ball joints or bushings into/from suspension components of vehicles. In general, the press includes first and second frame portions, a spine/shaft coupling the first and second frame portions together, and actuators coupled to one of the first and second frame portions. The actuators are sized and spaced such that combined forces of the actuators minimize a bending moment (and bending stress) about the shaft. The actuators may also share a feed line that provides for equal pressure across both actuators. This reduces an axis of bending of the shaft, and causes the first and second frame portions to remain substantially parallel and the force in line with an axis of motion to install or remove the ball joint.

A chassis component for a wheel suspension which has a strut arrangement with at least one strut which is in the form of a profile component with an open cross-section. The at least one strut has a profile base and two wall sections that extend away from the profile base. An articulation point is provided, at least at one end of the strut, for receiving two joint components movably connected to one another, namely, a first joint component having a spherical joint body and a second joint component that rotatably and/or pivotably holds the joint body. In the area of the at least one articulation point, the wall sections have first and second joint accommodation apertures arranged opposite one another. A cylindrical sleeve is pressed in between the first joint accommodation aperture and the second joint accommodation aperture and keeps the opposite wall sections apart from one another.

A boot that protects a moveable joint and retains lubricant associated with the joint. The wall of the boot includes a venting aperture that is protected by a surrounding barrier structure.

A suspension device for an in-wheel motor may include: a buffer part coupled to a vehicle body, and configured to absorb shock; an arm part coupled to the vehicle body, disposed at each of a top and bottom of the vehicle body, and coupled to the buffer part; a support part coupled to the arm part, and configured to be movable upward and downward; one or more connection parts rotatably mounted on the support part, provided as a pair of connection parts, and configured to serve as a steering axis; and a fixing part mounted on the connection part, rotated in connection with the connection part, and coupled to an in-wheel motor.

A vehicle may include: a floor panel; a rocker extending along a side edge of the floor panel; a rear side member located on a rear side of the rocker and extending along a front-rear direction of the vehicle; and a suspension. The suspension may include a trailing arm; and a bracket connected to the trailing arm via a bush. The bracket may be fastened to the rocker at a first fastening point by a first bolt and fastened to the rear side member at a second fastening point by a second bolt.

An independent suspension assembly for a vehicle, said assembly including: a suspension arm pivotally attachable at a first end to a point fast with the vehicle; a support member for rigid attachment of a lower end of a resilient member at a remote end of the suspension arm the resilient member having a remote side and a near side, the remote side being further from said point than the near side; and a pivoting mounting assembly attachable to the vehicle for attachment of an upper end of the resilient member; wherein pivoting of the suspension arm causes the resilient member to elicit pivoting of the pivoting assembly for minimizing a difference in lengthening between the remote and near sides of the resilient member.

An apparatus and methods are provided for a rear portal trailing arm assembly for a vehicle rear suspension. The trailing arm assembly comprises a CV joint hub for coupling with a transaxle and a wheel hub for coupling with a rear wheel. A gear transfer case extends rearward from the CV joint hub to an axle case and functions similarly to a rear trailing arm. Forward mounts facilitate coupling the gear transfer case to the chassis such that the trailing arm assembly pivots vertically with respect to the chassis. A rearward mount facilitates coupling a strut with the gear transfer case to control the vertical motion of the rear wheel. Multiple gear assemblies are meshed within the gear transfer case. An axle is coupled with the meshed gear assemblies and housed within the axle case, such that torque applied to the CV joint hub is communicated to the wheel hub.
