摘要： Disclosed is a tensioner for use in an engine. The tensioner comprises a fixed structure that fixes to the engine. A movable structure is mounted for movement relative to the fixed structure in a belt tensioning and opposite directions. A pulley member has a belt engaging surface that engages with the belt. One of the fixed and movable structures has an interior surface defining a fluid chamber containing fluid and the other includes a chamber dividing structure. The chamber dividing structure defines first and second chamber portions on opposing sides thereof. A biasing element biases the movable structure in the tensioning direction to tension the belt. Relative movement of the movable structure in the tensioning direction displaces fluid from the first to the second chamber portion and increases fluid pressure in the first chamber portion and decreases fluid pressure in the second chamber portion, and the reverse occurs during movement of the movable structure in the opposite direction. The chamber dividing structure allows the fluid to flow between the chamber portions in a restricted manner so as to yieldingly resist the relative movement of the movable structure and thereby dampen such movement. The chamber dividing structure is constructed such that the fluid flow restriction is greater when the movable structure moves in the opposite direction than in the tensioning direction, thereby providing the movable structure with greater resistance to movement in the opposite direction than in the tensioning direction.

摘要： A hub adapter used to modify a bicycle wheel hub to provide for the mounting of a disc brake rotor and/or for the repositioning of the wheel spoke mount flange to accommodate the additional components of a disc brake system. The hub adapter may be fixed to the host non-disc wheel hub by fastening bolts passing through the original spoke mounting holes or by other fastening means. The hub adapter may provide standard mounting holes for a disc brake rotor to be fixed to the hub adapter with fastening bolts. The hub adapter provides alternate spoke mounting holes on an alternate spoke flange, positioned in such a way so as to provide adequate clearance for disc brake components such as the disc brake caliper assembly, or in such a way as to change the length of the spokes and to modify the wheel stiffness. The hub adapter effectively becomes integral to the host wheel hub and critical to the primary function of the wheel hub, that is transferring load from the frame to the wheel.

摘要翻译： 一种用于修改自行车轮毂以提供盘式制动器转子的安装和/或用于重新定位轮辐安装法兰以适应盘式制动系统的附加部件的轮毂适配器。 轮毂适配器可以通过穿过原来的轮辐安装孔或其他紧固装置的紧固螺栓固定到主机非盘轮毂。 轮毂适配器可以提供用于盘式制动器转子的标准安装孔，以用紧固螺栓固定到轮毂适配器。 轮毂适配器在备用轮辐凸缘上提供备用轮辐安装孔，以这样的方式定位，以便为诸如盘式制动钳组件的盘式制动器部件提供足够的间隙，或者以改变轮辐长度的方式 并修改车轮刚度。 轮毂适配器有效地成为主轮毂的一体，并且对于轮毂的主要功能至关重要，即将载荷从框架传递到车轮。
