Problems solved by technology

[0007] That is to say, in the case of sudden braking, the higher the friction force (BFf) of the road surface will make the The greater the forward inertia force, the easier it is to cause the locomotive to roll over
This rollover is caused by the excessive forward inertial force and high center of gravity (high forward inertia force and high center of gravity) of the rider and the locomotive, rather than braking on the road with a low coefficient of friction; In this case, the anti-deadlock braking system 1' is absolutely unable to prevent the accident of forward tipping and rollover

Abstract

The present invention proposes a braking system with the function of preventing front overturning. According to the suspension travel signal monitored by the suspension travel sensor, the electronic control unit can determine whether the vehicle has a tendency to tip over; A signal is sent to the drive unit, so that the drive unit drives the piston in the direction of decompression and closes the fluid passage to prevent the pressure from continuing to increase. In addition, the volume of the bottom liquid chamber inside the hydraulic valve will increase with the movement of the piston, so that the hydraulic pressure of the bottom liquid chamber of the hydraulic valve will decrease; in this case, the braking mechanism will be reduced due to the downward pressure of the brake fluid. The braking action of the (front wheel) is reduced to achieve the effect of reducing the braking resistance, thereby preventing the vehicle from tipping forward.

Description

technical field [0001] The present invention relates to the technical field of braking systems, in particular to a braking system with the function of preventing forward tilt and overturning, which is specially applied to vehicles with short wheelbase and high center of gravity. Background technique [0002] Vehicles with a short wheelbase and a high center of gravity are commonly used means of transportation by modern people, such as electric bicycles, motorcycles, and motorcycles. Taking motorcycles as an example, they are usually equipped with a set of braking systems; however, when the rider is driving the motorcycle on a slippery road, the sudden braking behavior of the rider often causes the brakes to lock up, leading to accidents such as rollover or vehicle skidding. [0003] In view of this, currently commercially available locomotives are usually equipped with an anti-lock braking system (Anti-lock Braking System, ABS). see figure 1 , is a structure diagram showin...
