Problems solved by technology
Although the anti-lock braking system for two-wheeled vehicles has been relatively mature in China, most of them are composed of valve blocks, pressure increasing and reducing valves, eccentric motors, accumulators and an electronic control unit. The solenoid valve in the mechanical control valve block is opened or closed to maintain the maximum deceleration and vehicle stability when the vehicle encounters emergency braking during straight-line driving. When braking in an emergency, it is easy to cause vehicle instability and rollover due to improper control

The invention provides a two-wheeled vehicle anti-lock braking system with the following structure. The two-wheeled vehicle anti-lock braking system comprises a hydraulic driving unit and an electronic control unit, wherein the hydraulic driving unit comprises a valve body, an eccentric motor and an energy accumulator, a main cylinder oil port and a wheel cylinder oil port are formed in the valvebody, a control channel is formed in the valve body, the control channel comprises a first electromagnetic valve, a second electromagnetic valve, a pump oil inlet one-way valve, a plunger pump and a pump oil outlet one-way valve, a first flow channel is formed between the main cylinder oil port and the first electromagnetic valve, and a pressure sensor is connected with the first flow channel andused for detecting the pressure of the main cylinder in the braking process and transmitting a detected signal to the electronic control unit. The pressure sensor is arranged on the first flow channel, the pressure of the brake master cylinder in the braking process can be monitored in real time, the dynamic control characteristic of the electromagnetic valve is changed through the pressure fluctuation reaction of the brake master cylinder, the working pressure of the wheel cylinder is controlled more accurately, and thereby stability and an optimal deceleration state of a vehicle are guaranteed.
Description
technical field [0001] The invention relates to the technical field of brake systems, in particular to a brake anti-lock brake system for a two-wheeled vehicle. Background technique [0002] As people pay more and more attention to traffic safety, two-wheeled vehicles equipped with anti-lock braking systems are more and more popular because of their high driving safety. The brake anti-lock braking system is the core of the two-wheeled vehicle braking technology. Its function is to automatically control the braking force of the brake when the two-wheeled vehicle is braking, so that the wheels are not locked and always in a state of rolling and sliding. In order to prevent the two-wheeled vehicle from drifting, during the braking process, the adhesion between the wheel and the ground is always maintained at the maximum, thereby ensuring the minimum braking distance, and at the same time ensuring the braking stability of the vehicle and improving driving safety. Although the a...
