Problems solved by technology

However, due to the compact structure of the motorcycle, the brake system is different from that of the car brake system, so it is difficult to use the electronic anti-lock brake device on the car on the motorcycle.
At the same time, compared with the mechanical anti-lock brake system, the electronic anti-lock brake system has a complex structure and high cost
[0003] The existing mechanical anti-lock brake device includes a housing, an oil inlet joint connected to the brake master cylinder installed on the housing and an oil outlet joint connected to the brake sub-cylinder, mainly using the input oil pressure, that is, the hydraulic pressure in the oil inlet passage. Oil is used to control the braking force to prevent lock-up, the work response is slow, and the reliability is poor

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] refer to figure 1 , the hydraulic brake anti-lock device for motorcycles includes a housing 3, an oil inlet joint 1 and an oil outlet joint 16 installed on the housing, the housing has an axial through hole, and the top of the through hole is screwed with an upper The adjustment bolt 7 is screwed with the lower adjustment bolt 15 at the bottom, and the piston rod 9 is arranged in the through hole, which is sealed between the piston rod and the housing, and the piston rod can move freely up and down. An upper preload spring 8 is provided in the oil chamber 10 formed by the upper end surface of the piston rod 9 and the upper adjusting bolt, and a lower preload spring 12 is provided in the cavity formed by the lower end surface of the piston rod 9 and the lower adjusting bolt 15. The piston rod is balanced under the action of the upper and lower pre-tension springs, an...

Abstract

An ABS for the hydraulic brake of motorcycle is composed of a casing with oil inlet jointer, oil outlet jointer, axial through hole, a piston rod in said through hole, the upper and lower regulating screw bolts at the upper and lower ends of said through hole, the upper and lower pre-stretching springs in the cavities between upper (and lower) regulating screw bolt and piston rod, the oil returning channel and cavity is said casing, the feedback oil channel, and a one-way valve in said oil returning cavity. It can perform dot braking.

Description

technical field [0001] The invention relates to a brake device, in particular to a hydraulic brake anti-lock brake device for motorcycles. Background technique [0002] The braking system of a motorcycle generally transmits the hydraulic braking force through the brake master cylinder to the brake cylinder so that the brake pads hug the tires, thereby achieving deceleration and parking. When the emergency brake is applied, the braking force suddenly increases, causing the wheels to lock, the direction of the vehicle is out of control, and it is easy to roll over, causing traffic accidents. At present, on high-end cars, an electronic anti-lock braking system has been installed to avoid accidents caused by wheel locking during emergency braking. The electronic anti-lock brake device detects the rotation speed of the wheel through the wheel speed sensor, and the detection signal is collected into the electronic controller for analysis. Once the wheel is about to lock, the elec...
