  • Patent number: 7703429
    Abstract: A balancing shaft unit for balancing inertia or torque in an internal combustion engine of a motor vehicle. The balancing shaft unit includes a housing part and at least one balancing shaft having at least one counterweight. The housing part is made in one piece and has at least two integrated bearing sections with a respective bearing opening. A respective cut-out is formed at longitudinal ends of the balancing shaft in which a respective bearing pin is arranged that is rigidly connected to the balancing shaft and which has a cylindrical bearing section that is supported in a respective one of the bearing openings.

  • Patent number: 7571703
    Abstract: The invention relates to a balancing shaft, whose balancing weight is located between two cylindrical bearing surfaces and which is configured as one piece with said weight. The end cross-sections of the balancing weight are circular segments that are delimited by an arc and a secant. The aim of the invention is to configure the balancing shaft in such a way that the mass effect and rigidity are optimal. To achieve this, the contours of the balancing weight on the plane that is fixed by the secants of the two end cross-sections taper from the two end cross-sections towards the longitudinal centre and the contours on the normal plane form a straight line in relation to said plane.

  • Patent number: 7506628
    Abstract: The invention relates to a balancing shaft unit for piston machines, in particular internal combustion engines, for installation in a housing with non-divided bearing seats. Said shaft unit consists of at least one balancing shaft, which is configured as one piece with its balancing weight or weights. To allow the shaft unit to be installed in a non-divided housing without any restrictions being placed on its bearing, at least one bearing of the balancing shaft is formed by a narrowing of the balancing shaft that acts as a bearing journal and by a sub-divided bearing ring that is fixed to the housing, whose external diameter is greater than the external diameter of the balancing weight or weights.
