auxiliary brake

technical field

The invention relates to a brake transmission structure of a two-wheeled vehicle, in particular to an auxiliary brake capable of synchronously controlling the braking force and force of the front and rear wheels.

Background technique

General linear two-wheeled vehicles such as bicycles, engine-powered locomotives (motorcycles), electric locomotives, etc. mostly use hand-pulled brake systems. Usually, the left handle and the right handle are each equipped with a brake lever, and through the brake pull cord (brake brake) Lines) are respectively connected to the front wheel brake and the rear wheel brake to achieve the purpose of braking the front and rear wheels by pulling the brake lever. It is worth mentioning that when braking, the friction between the tire and the ground is used to achieve the deceleration effect. When a straight-line two-wheeled vehicle (such as the aforementioned bicycle and various types of locomotives) is running, both the person and the vehicle maintain a forward direction. Inertial force, if the brake is not operated properly, it is inevitable that slipping or overturning will occur; especially in an emergency, people will often unconsciously hold the brake lever tightly. If the brake is directly controlled to lock the rear wheel, it is easy to Tire skidding or tail flicking occurs due to insufficient tire friction, and if the front wheel is directly locked inadvertently, it is most likely to overturn due to inertia. Note.

The correct braking method is known to most drivers. For example, when braking, it is best to brake the rear wheels first, and then brake the front wheels. Partial force can most effectively avoid accidents caused by improper operation. There are several types of synchronous brakes on the market today that can simultaneously control the front and rear wheel brakes with a single brake lever, but they all have a considerable volume or weight, which is not conducive to placing on a lightweight car body, which not only affects the appearance but also hinders the The balance of the car body, in view of this, the inventor of this case is committed to the way of research and improvement, with its creation experience for many years, finally has the present invention to produce, proposes the invention patent application according to law.
