Description
Technical field
The invention belongs to motorcycle brake technical fields, and in particular to a kind of hydraulic brake valve and brake fluid system.
Background technique
Braking system is to ensure that motorcycle safety travels the most key active safety feature, so motorcycle brake system
Basic demand be exactly:No matter motorcycle is under the conditions ofs any speed, load, height attachment coefficient road surface and weather etc., really
Protecting driver can realize that vehicle is steady, rapidly slows down in braking process by shirtsleeve operation, until parking.Motorcycle
Braking system is different from automobile, since motorcycle shaft is away from short, so the centroid position of motorcycle is higher than automobile.When braking, mass center
Position forward excursion it is big, front-wheel needs bigger brake force, could gradual braking motorcycle.
However most of traditional two-wheeled motor vehicle uses forward and backward independent braking system, equipped with this braking system
Motorcycle just must reasonably distribute the operating force of hand, foot in braking process, to obtain biggish braking deceleration, make
Forward and backward tire makes full use of the attachment coefficient on road surface, but in real life, user is difficult to accomplish the conjunction of front and rear wheel brake force
Reason distribution.For motorcycle, according to the situation of vehicle load, the attachment coefficient and vehicle of pavement of road in braking process
It is critically important again that the composite factors such as the abrasion condition of tire, which distribute brake force, for example, if front wheel brake, front-wheel is used alone
Just it is possible to locking occur, and then loses steering capability, lead to great overturn accident;If rear service brake is used alone, no
But brake efficiency is low, and is likely to result in rear lock, be easy to cause defective steering stabilizer.
Currently, application of the ABS technology on high-end two-wheeled motor vehicle is relatively broad, although the application of the technology is greatly
Ground improves the brake safe performance of two-wheeled motor vehicle, but expensive price ordinary consumer is difficult to bear.Therefore, this field
Technical staff it is necessary to design it is a kind of it is easy to operate, braking force distribution is reasonable and cheap, and allow motorcycle front and back wheel simultaneously
The brake valve and braking system of gradual braking.
