In bicycles, the combination of suspension ears and hooks is an important component related to the connection between the frame and the wheels. Here is the relevant introduction:
Structure and function
Hook Claw: The hook claw is a part of the frame, located at the end of the rear triangle of the frame, one on each side, and the wheel hub is installed between the hook claws. Its main function is to fix the wheels, allowing them to be stably installed on the frame and withstand various forces from the wheels, such as impact force during riding and braking force during braking. For quick release wheels, the hook usually has an open part to facilitate the installation and removal of the quick release shaft; For cylinder axle wheels, the claws are closed, and the wheel is fixed between the two claws on both sides through the cylinder axle.
Lifting ear: Lifting ear generally refers to a small component installed on the hook or frame, usually used for installing the rear gearbox. It provides a fixed point for the rear gearbox, allowing it to accurately control the switching of the chain between different flywheels. Some lifting ears are directly integrated onto the hook, while others are detachably installed on the hook or frame through screws or other means. In order to pursue performance and lightweight, some high-end bicycles use suspension ears made of materials such as carbon fiber to reduce weight while ensuring strength.
Adjustable suspension ear hook mechanism: Some bicycle hook mechanisms adopt adjustable suspension ear design, such as the relevant mechanism invented by Huizhou Xidesheng Bicycle Co., Ltd. In this design, the upper and lower ends of the left hook are fixedly connected to the left upper fork and the left lower fork, respectively. There is a left adjustment groove on the inner side of the left hook, and the left lifting ear is set in the left adjustment groove. The outer side of the left lifting ear forms a left sleeve for passing through the cylinder shaft. By adjusting the waist shaped through-hole and locking screw on the left adjustment slot, the position of the left hanging ear can be adjusted, thereby adjusting the front and rear positions of the left and right hooks, making it convenient to adjust the tightness of the chain. At the same time, it has the characteristics of compact structure and beautiful appearance.
When using and maintaining bicycles in daily life, it is important to check whether the connection between the suspension ears and claws is secure, whether there is any deformation, cracks, or other damage, to ensure that they can function properly and ensure the safety and performance of the bicycle.
