摘要： Engine accessory drives are used with internal combustion engines to drive one or more accessories and are conventionally driven off a front end drive assembly. However, driving the accessories off the front end drive assembly has implications in respect of both increased engine noise and extended engine length. An engine accessory drive in accordance with this invention reduces engine noise and engine length. An engine accessory drive for transmitting a force between a first end (2) and a second end (3) of an engine (1) comprises a primary drive (18) locatable at the first end (2) of the engine.

摘要： Balance shaft assemblies are used in internal combustion engines to dampen primary and second order inertia forces. Known balance shaft assemblies typically require precision manufacturing and a rigid frame or housing. A balance shaft assembly (1) in accordance with this invention provides a low cost and less complex solution to engine balancing. The balance shaft assembly (1) includes an elongate housing (2) having a front end and a rear end, a balance shaft (5) which is rotatably supported between a front end bearing (6), a rear end bearing (7) and an intermediate bearing (12)in the housing (2). The housing (2) is transversely flexible relative to the balance shaft (5) to accommodate misalignment of the intermediate bearing (12) relative to the front and rear end bearings (6, 7). Consequently, the balance shaft assembly (1) can be less complicated and manufactured at a lower cost than known balance shaft assemblies.

摘要翻译： 平衡轴组件用于内燃机以抑制一级和二级惯性力。 已知的平衡轴组件通常需要精密制造和刚性框架或壳体。 根据本发明的平衡轴组件（1）为发动机平衡提供了低成本和不太复杂的解决方案。 平衡轴组件1包括具有前端和后端的细长壳体2，可旋转地支撑在前端轴承6和后端轴承7之间的平衡轴5， 在壳体（2）中的中间轴承（12）。 壳体（2）相对于平衡轴（5）是横向柔性的，以适应中间轴承（12）相对于前端和后端轴承（6,7）的未对准。 因此，平衡轴组件（1）可以不那么复杂并且以比已知的平衡轴组件更低的成本制造。
