A coupled torsion beam axle (CTBA) bushing is press-fitted into a bushing bracket provided at a tip of a trailing arm at each of two opposite sides of a CTBA suspension system. In particular, the CTBA bushing includes: an outer pipe including a through-hole formed therein; an inner pipe positioned in the through-hole; and a bushing rubber disposed in the through-hole and positioned between an outer peripheral surface of the inner pipe and an inner peripheral surface of the outer pipe, in which the bushing rubber includes: first compounds extending in a first direction, which is a diameter direction of the inner pipe, with the inner pipe interposed therebetween; and a second compounds integrated with the first compounds and extending in a second direction, which is perpendicular to the first direction, with the inner pipe interposed therebetween.

A twist beam for a suspension of a motor vehicle comprises a body-side inner part having a bearing-receiving section for receiving a body-side bearing, and a wheel carrier-side outer part having a bearing-receiving section for receiving a wheel carrier-side bearing, the outer part and the inner part being separate components which are made of different materials and are firmly connected to each other.

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.

Torsion beam axles for vehicles are disclosed. An example torsion beam axle disclosed herein includes a first side assembly, the first side assembly including a longitudinal member and a receiver. The example torsion beam axle further including a second side assembly, and a cross strut extending transversely between the first side assembly and the second side assembly.

The invention relates to a method for producing a bent torsional profile comprising the following process steps: a) provision of a plate made of planar sheet metal, b) reshaping of the plate through the introduction of a bent trough oriented in the longitudinal direction of the plate in a central length portion (6) of the plate at a distance from the front edges of the plate, forming legs between the trough and the longitudinal edges of the plate, c) reshaping of the legs in such a manner that an open profile is created, d) reshaping of the legs in such a manner that a hollow profile is produced, wherein a longitudinal gap is formed between the two legs over the entire longitudinal extent thereof and wherein an air gap is created between the legs and the trough in the region of the trough, e) joining of the two legs over the entire longitudinal gap.
