Description
Technical Field
The utility model relates to the field of valve bodies, in particular to a CBS linkage proportional valve of a monorail vehicle.
Background
In most of the existing single-rail vehicles such as motorcycles, electric vehicles and the like, the front wheels and the rear wheels generally adopt independent braking systems, and the independent control is carried out by means of braking handles on double handles. Accordingly, these prior art brakes rely primarily on human feel and experience and operators rely primarily on hand feel to apply force to the braking mechanisms of the front and rear wheels to achieve the desired braking effect.
The braking mode has a certain danger for unfamiliar personnel, is easy to operate improperly, and can cause serious rollover accidents because if the front wheels are used for braking independently, the front wheels are possibly locked, and then the steering capability and the vehicle tilting are lost; if the rear wheel is used singly, the braking efficiency is low, the rear wheel is possibly locked, and the vehicle is easy to sideslip; if front and rear brakes are simultaneously applied, when the braking force is large enough in the braking process, the rear wheels are generally locked in advance in the braking process, so that the tires are rubbed on the ground. Therefore, the existing vehicles cannot automatically and reasonably distribute the front and rear braking forces, and are easy to cause danger.

Example 1
1-2, The embodiment provides a CBS linkage proportional valve of a monorail vehicle, which comprises a shell 100, wherein one side of the shell 100 is provided with a first oil inlet 101 and a second oil inlet 102, and the other side of the shell 100 is provided with a first oil outlet 111 and a second oil outlet 112; a piston cavity 103 is arranged in the shell 100, and the first oil inlet 101, the second oil inlet 102, the first oil outlet 111 and the second oil outlet 112 are communicated with the piston cavity 103; a piston 104 is movably arranged in the piston cavity 103; a first through hole 121 and a second through hole 122 are formed at the communication position of the first oil inlet 101 and the piston cavity 103, and a Y-shaped sealing ring 105 is arranged on one side of the piston 104 close to the first oil inlet 101; the diameter of the first through hole 121 is d, and d is more than or equal to 0.5mm and less than or equal to 0.7mm.
The embodiment relates to a CBS linkage proportional valve of a monorail vehicle, which is used for connecting a brake hydraulic system of front and rear wheels of the monorail vehicle, and realizing the technical effect of automatic front and rear braking force distribution, and the working principle is as follows:
When parking braking is needed, the hand or foot applies acting force to the handle by combining the existing braking system, and the braking main pump and the oil pipe in the existing braking system transmit oil with certain pressure to the linkage valve of the embodiment. It is conceivable that oil with a certain pressure enters the linkage valve of the present embodiment through the first oil inlet 101 and the second oil inlet 102, for example, when the present embodiment is applied to a bicycle, the first oil inlet 101 and the second oil inlet 102 correspond to the brake handles on the left and right sides, respectively, for responding to the input of the braking action, and the first oil outlet 111 and the second oil outlet 112 are used for controlling the output of the brake system, and the same applies to the motorcycle. It should be noted that the proportional valve of this embodiment is initially filled with hydraulic fluid.
When the first oil inlet 101 on the left side is filled with oil, the oil is actually pressed into the piston cavity 103 through the first through hole 121, hydraulic oil in the piston cavity 103 is pressed, the oil pressure is output outwards from the first oil outlet 111 on the left side, and the braking force output of a brake or a braking system connected with the first oil outlet 111 can be controlled, so that single-wheel braking is completed.
When the second oil inlet 102 on the right side is filled with oil, part of the oil directly flows to the second oil outlet 112, the oil pressure is output outwards from the second oil outlet 112 on the right side, and the braking force output of a brake or a braking system connected with the second oil outlet 112 can be controlled to finish the braking of another wheel.
Further, when the oil enters the right second oil inlet 102, when the oil reaches a certain pressure, the piston 104 is pushed to move towards the first oil outlet 111, so as to provide pressure for a brake or a brake system of the other wheel, and realize the linkage braking of the two wheels. Therefore, in this embodiment, the linkage braking of the front wheel and the rear wheel can be achieved only by controlling the oil inlet of the second oil inlet 102 on the right side, that is, by a single-hand or single-foot operation.
In this embodiment, the first through hole 121 is designed to provide oil to the left side area of the piston cavity 103, and the diameter d of the first through hole 121 is set to be in the range of 0.5 mm-0.7 mm, so as to reduce the abrasion of the Y-shaped sealing ring 105 during the back and forth movement. In a preferred embodiment, d is 0.5mm.
In this embodiment, the second through hole 122 is designed to supplement oil and balance oil pressure, so as to prevent the piston 104 from forming vacuum and breath holding in the piston cavity 103 during the movement process.
In summary, the embodiment solves the problem of automatic front and rear braking force distribution, and can automatically distribute front and rear braking force without relying on manual control, thereby achieving the expected braking effect, having higher braking efficiency and ensuring the safe, rapid and stable parking of the monorail vehicle.
Example 2
1-2, Compared with the technical scheme of the embodiment 1, the CBS linkage proportional valve of the monorail vehicle can be improved as follows: when the piston 104 is at the initial position, the distance from the first through hole 121 to the end face of the sealing lip of the Y-shaped sealing ring 105 is s, and s is more than or equal to 0.3 and less than or equal to 0.6mm. When the piston 104 is located at the position shown in fig. 1, namely, the initial position, and when the piston 104 moves towards the first oil outlet 111, the distance s is actually an idle stroke, no braking effect is generated at this time, and the situation that linkage response is too sensitive and front and rear wheel linkage braking response is too sensitive is avoided, so that accidents are easy to occur.
Example 3
With reference to fig. 1-2, compared with the technical scheme of embodiment 1 or 2, the CBS linkage proportional valve of the monorail vehicle of the present embodiment can be improved as follows: the piston cavity 103 comprises a large-diameter cavity and a small-diameter cavity, the piston 104 comprises a large-diameter section and a small-diameter section, the outer diameter of the large-diameter section is matched with the inner diameter of the large-diameter cavity, and the outer diameter of the small-diameter section is matched with the inner diameter of the small-diameter cavity. In this embodiment, since the oil inlet pressure of the second oil inlet 102 on the right side is constant, the oil pressure needs to be overcome in order to move the piston 104, and when the diameter of the large diameter section of the left piston 104 is larger than that of the small diameter section of the right piston 104, the braking force of the brake connected to the second oil outlet 112 can be ensured to be larger than that of the brake connected to the first oil outlet 111 on the left side. The arrangement accords with the operation logic, and can realize better braking control effect. It is contemplated that the large diameter section and the small diameter section of the piston 104 may be sized to correspond to the distribution of the linkage braking force.

The arrangement of the first sealing ring 131 in this embodiment ensures the transmission of the oil hydraulic force on the one hand, and the smooth movement of the piston 104 on the other hand, and reduces the wear of the piston 104 at the same time.
