Description

Technical Field

[0001] The invention relates to a control valve for a CBS system of a motor vehicle. Background Art

[0002] At present, ABS (Antilock Brake System) technology has been widely used in high-end two-wheeled motorcycles. Although the application of this technology greatly improves the braking safety performance of two-wheeled motorcycles, the high price is unaffordable for ordinary consumers. Therefore, it is particularly important to design a two-wheeled motorcycle linkage braking system that is simple to operate, has reasonable braking force distribution and is inexpensive. In recent years, a new type of integrated front and rear wheel linkage braking system (Combined Brake System, referred to as CBS) has been developed and actual vehicle tests have been carried out. The test results show that the device has a high deceleration performance, for example:

[0003] The Chinese utility model patent with publication number CN219770090U discloses a two-way check control valve for a motorcycle CBS system. The two-section valve body connection structure makes the utility model simple in structure, easy to install, and convenient for maintenance. The check structure prevents brake fluid from flowing back, improving safety. The two-section valve body arrangement enables the check structure to achieve a two-way check effect, which has a good use effect. However, the defects are as follows:

[0004] The two valve bodies are fixed by bolts. When non-professionals disassemble and assemble them, it is difficult to find special tools to ensure that the bolts reach the appropriate torque. Too much torque can easily cause thread slippage and damage the screw threads on the two valve bodies. Too little torque can easily cause the bolts to loosen, affecting the sealing between the two valve bodies, causing brake oil leakage, affecting the braking effect, and creating safety hazards.

[0061] The motor vehicle CBS system control valve provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0062] Embodiment 1:

[0063] like Figures 1 to 6As shown, an embodiment of the present application provides a control valve for a CBS system of a motor vehicle, comprising a left valve body 105 with a left valve chamber 101, a left fluid inlet channel 102, a left brake oil pipe 103, and a plurality of mounting holes 104, a right valve body 110 with a right valve chamber 106, a right fluid inlet channel 107, a right brake oil pipe 108 and a plurality of through holes 109, a plunger 111, a plunger spring 112 and a plurality of mounting bolts 113, and also comprising a plurality of connecting members 2, which can be respectively floatably mounted in each mounting hole 104 for cooperating with each mounting bolt 113, and each of which is internally provided with a locking mechanism 3 for cooperating with the corresponding through holes 109.

[0064] Furthermore, each connecting member 2 includes a sleeve 21, the lower end of which is closed and the inner cavity is provided with an internal thread; a fixing bolt 22, which can be slidably installed in the sleeve 21 and the lower end extends out of the sleeve 21; wherein the locking mechanism 3 is installed between the sleeve 21 and the inner wall of the corresponding through hole 109.

[0065] Furthermore, the locking mechanism 3 includes a plurality of composite grooves 31, which are arranged at intervals on the top circumference of the sleeve 21; a side ring groove 33, which is arranged at the bottom of the through hole 109, and a plurality of locking grooves 34 are arranged on its circumferential wall;

[0066] A plurality of engaging members 35 are movably installed in each composite slot 31 and adapted to each engaging slot 34 ; a plurality of unlocking members 36 are respectively used to disengage each engaging member 35 from the corresponding engaging slot 34 .

[0067] In this embodiment of the present application, due to the adoption of the above-mentioned structure, through the left valve chamber 101, the left fluid inlet channel 102, the left brake oil pipe 103, and the left valve body 105 with a plurality of mounting holes 104, the right valve body 110 with the right valve chamber 106, the right fluid inlet channel 107, the right brake oil pipe 108 and the plurality of through holes 109, the plunger 111 and the spring, the brake oil enters the left valve chamber 101 through the left fluid inlet channel 102, and then enters the rear brake caliper through the left brake oil pipe 103 to achieve rear braking, the brake oil enters the right valve chamber 106 through the right fluid inlet channel 107, pushing the piston to move into the left valve chamber 101, and the hydraulic oil in the left valve chamber 101 and the right valve chamber 106 respectively enter the front brake caliper and the rear brake caliper through the left brake oil pipe 103 and the right brake oil pipe 108, thereby achieving front and rear linkage.

[0068] When installing the left valve body 105 and the right valve body 110, the two ends of the plunger 111 are inserted into the left valve cavity 101 and the right valve cavity 106, and then the left valve body 105 and the right valve body 110 are closed, so that each mounting hole 104 corresponds to each through hole 109, and then the mounting bolt 113 is inserted into each through hole 109, and the mounting bolt 113 is tightened to make one end of each sleeve 21 extend into the corresponding side ring groove 33 until the bottom of each sleeve 21 is tightly pressed against the nut part of the corresponding fixing bolt 22, and at this time, each engaging member 35 is engaged with the corresponding slot 34, completing the left valve body 105 and the right valve body. When the left valve body 105 and the right valve body 110 need to be separated from each other during the combined installation of 110, loosen each mounting bolt 113 to disengage each mounting bolt 113 from the corresponding sleeve 21 and the corresponding through hole 109. At this time, each engaging member 35 is still engaged with the corresponding slot 34, and the left valve body 105 and the right valve body 110 are still fixed to each other. Professionals are required to use special tools to operate each unlocking member 36 at the same time to disengage each engaging member 35 from the slot 34 at the same time. Only then can each engaging member 35 be disengaged from the corresponding slot 34, so that the left valve body 105 and the right valve body 110 can be separated.

[0069] Embodiment 2:

[0070] like Figures 4 to 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the connecting member 2 also includes a convex ring 23, which is arranged at the top of the side ring groove 33; an inner ring groove 24, which is arranged at the top of the sleeve 21; a spring 25, which is sleeved on the inner side of the convex ring 23, with the top end abutting the top end of the side ring groove 33, and the lower end being located in the inner ring groove 24.

[0071] Furthermore, the composite groove 31 includes an outer groove 311, which is used to accommodate the locking member 35; a vertical hole 312, which is arranged on the top of the sleeve 21 and connected to the outer groove 311 on one side through a connecting groove; an inner groove 313, which is arranged on the inner wall of the sleeve 21 and connected to the vertical hole 312, and the unlocking member 36 is installed in the vertical hole 312, the connecting groove and the inner groove 313.

[0072] Furthermore, the engaging member 35 includes an engaging flap 351 , one end of which is flipably mounted on the top of the outer groove 311 via a hinge shaft 352 ; wherein the unlocking member 36 is movably connected to the inner side wall of the engaging flap 351 .

[0073] When the locking cam 350 is in the state of being unlocked, the locking cam 351 is in the state of being unlocked, and the cam 350 is in the state of being unlocked.

[0074] Embodiment 3:

[0075] like Figure 5 and Figure 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the unlocking member 36 includes a lifting rod 361, which can be slidably installed in the vertical hole 312; a lifting slider 362, which can be slidably installed in the inner groove 313 and is fixedly connected to the lifting rod 361; a connecting rod 363, one end of which is hinged to the lifting rod 361, and the other end passes through the connecting groove and extends into the outer groove 311, and is hinged to the engaging member 35.

[0076] Furthermore, the unlocking member 36 also includes a second spring 364 , which is arranged at the bottom end of the lifting rod 361 ; and a blocking bead 365 , which is interference-fixedly installed at the top end of the vertical hole 312 .

[0077] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the sleeve 21 extends into the corresponding side ring groove 33, each engaging flap 351 is pushed into the corresponding outer groove 311, and each lifting slider 362 is pushed down in the corresponding vertical hole 312 through the corresponding connecting rod 363, each spring second 364 is pressed and locked, and each lifting slider 362 also descends in the corresponding inner groove 313. When each engaging flap 351 moves to correspond to the corresponding slot 34, each spring second 364 releases elastic potential energy, pushes each vertical rod to rise, and pushes the outer end of each engaging flap 351 into the corresponding slot 34 through the corresponding connecting rod 363. It is necessary to disengage each engaging flap 351 from the corresponding slot 34. When the cam 350 is in the state of being lifted and lowered, the spring 25 is used to release the elastic potential energy of the sleeve 21, pushing the sleeve 21 to slide outward from the corresponding side groove 33 until the engaging flaps 351 are away from the corresponding groove 34. At this time, the special tool can be taken out and the left valve body 105 and the right valve body 110 can be separated.

[0078] Embodiment 4:

[0079] like Figures 5 to 8 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes an outer ring groove 4, which is arranged on the adjacent end faces of the left valve body 105 and the right valve body 110; a sealing ring 5, which is arranged in the outer ring groove 4; an extrusion member 6, which is used to extrude the sealing ring 5 so that it bulges toward the plunger 111; and a plurality of anti-slip members 7, which are used to prevent the sealing ring 5 from escaping from the outer ring groove 4, and each anti-slip member 7 is fixed to each other through a connecting ring.

[0080] Furthermore, the extrusion member 6 includes a lower lifting ring 61, which can be floatably installed in the outer ring groove 4 and is fixedly connected to each sleeve 21 at the same time, and a plurality of upward triangular blocks 62 are arranged at intervals on the top; an upper lifting ring 63, which can be floatably installed above the lower lifting ring 61, and a plurality of downward triangular blocks 64 are arranged at intervals along the circumferential direction on the bottom, and each downward triangular block 64 is arranged at intervals from each upward triangular block 62, and is connected to each anti-slip component 7.

[0081] Furthermore, the anti-slip component 7 includes a blind hole 71, which is arranged at the bottom of the outer ring groove 4; a hollow tube 72, whose upper end is fixed to the upper lifting ring 63, and the lower end is inserted into the blind hole 71; a spring three 73, which is sleeved on the outside of the hollow tube 72 and is located below the connecting ring; a plurality of limiting vertical grooves 74, which are arranged at intervals along the circumferential direction on the lower peripheral wall of the blind hole 71; and a plurality of protrusions 76, which are installed at the bottom of the hollow tube 72 and slideably cooperate with the corresponding limiting vertical grooves 74.

[0082] Furthermore, the anti-slip component 7 also includes an insertion rod 75, which is inserted into the inner cavity of the hollow tube 72; a cylinder 79, which is fixed at the bottom end of the insertion rod 75 and is provided with an annular protrusion 78 at the connection with the insertion rod 75; a blocking bead 77, which is interference fixed at the top of the blind hole 71; wherein each protrusion 76 can be slidably inserted in the lower part of the peripheral wall of the hollow tube 72, and when the outer end is inserted in the corresponding limiting vertical groove 74, the outer peripheral wall of the annular protrusion 78 abuts against the inner end of each protrusion 76.

[0083] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during the closing process of the left valve body 105 and the right valve body 110, the upper lifting ring 63 first contacts with the top of the outer ring groove 4. As the left valve body 105 and the right valve body 110 continue to approach and close, the upper lifting ring 63, each downward triangular block 64 and each plug rod 75 all descend, and each upward triangular block 62 and downward triangular block 64 gradually move to the same horizontal height. During the process, the sealing ring 5 is squeezed to make the sealing ring 5 shrink inward, and the inner ring is pressed against the inner peripheral wall of the outer ring groove 4 to seal the gap between the left valve body 105 and the right valve body 110. When the left valve body 105 and the right valve body 110 are closed, the contact sealing performance between the inner peripheral wall of the sealing ring 5 and the inner ring of the outer ring groove 4 reaches a peak value. This sealing degree remains unchanged before each sleeve 21 is separated from the corresponding side ring groove 33. At this time, each spring three 73 is compressed and shortened, and each protrusion 76 is located at the lower end of each limiting vertical groove 74.

[0084] When each sleeve 21 is separated from the corresponding side ring groove 33, under the action of spring 1 25, each sleeve 21 descends, and the corresponding lower lifting ring 61 also descends, and each spring 3 73 releases elastic potential energy to push each hollow tube 72 and the lifting ring, the upper lifting ring 63 and each downward triangular block 64 to rise until the bottom surface of the lower lifting ring 61 contacts the top surface of the sealing ring 5. At this time, the upward triangular blocks 62 and the downward triangular blocks 64 are separated, releasing the inward extrusion of the sealing ring 5, and the sealing ring 5 is separated from the seal with the inner circumferential wall of the outer ring groove 4 under the action of its own elasticity.

[0085] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0086] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
