Description

Two-wheeled motor vehicle front and rear wheel brake linkage control device

This creation belongs to the technical field of brakes of two-wheeled motor vehicles, and especially refers to a new design of the brake linkage control device for the front and rear wheels of two-wheeled motor vehicles. In addition to the functions of increasing the braking efficiency and avoiding the danger of braking the front wheels alone, the creation mechanism is simple and more efficient. It can be installed on old motor vehicles without CBS, benefiting the vast number of old motor vehicle users.

When a motor vehicle such as a two-wheeled bicycle or a scooter is braked, the rear wheel should be braked first and then the front wheel should be braked to stabilize the body and avoid the risk of body tipping caused by braking the front wheel alone. The conventional locomotive brake system is designed to press the rear wheel brake handle to brake the rear wheel, and press the front wheel brake handle to brake the front wheel. When an emergency occurs, the correct operation method is to first press the rear wheel brake handle to brake the rear wheel and then press the front wheel brake handle to brake the front wheel. However, in a state of emergency, the driver often causes a crash due to wrong operation. For Taiwanese locomotives, the front brake handle is the right brake handle, and the rear brake handle is the left brake handle. Therefore, in order to improve braking safety, light locomotives are gradually required to be equipped with a linked braking system (CBS) or an anti-lock braking system (ABS). The linkage braking system is a braking system that allows the driver to control the front and rear wheels at the same time by pressing a single brake handle, reducing the risk of slippage or even rollover caused by single-wheel braking. In other words, the interlocking braking system can decelerate the front and rear wheels at the same time to maintain the stability of the body and reduce the chance of tire slippage. Taiwan's locomotive utilization rate is more popular. Starting from New Year's Day in 2019, the Ministry of Communications stipulated that it will force new locomotives to be manufactured in the future. It is necessary to install [Anti-lock Braking System (ABS)] or [Front and rear linkage braking system (CBS), CBS (Combination Braking System) is to allow the rider to brake, as long as the left or right side brakes, the front and rear wheels can be braked at the same time. Lower the wheel brake to cause a skid or a rollover. In other words, CBS can decelerate the front and rear wheels at the same time, maintain the stability of the fuselage, and reduce the chance of the rear wheel slipping], so as to improve safety [refer to my country's M586685 patent specification].
