Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology and relates to a dual CBS proportional valve for all-terrain four-wheeled vehicles. Background Technology

[0002] All-terrain four-wheel vehicles require two or three independent brake lines to ensure that if one or two brake lines fail, the other can still brake and decelerate normally, thus ensuring the safety of the rider.

[0003] Currently, all-terrain four-wheel vehicles require three independent brake oil circuits to meet the above conditions. Therefore, they need to work together by connecting independent proportional valves and independent foot brake pumps, which is relatively expensive and the oil circuit connection and disconnection are complicated. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a dual-CBS proportional valve for all-terrain four-wheeled vehicles that reduces costs, lowers structural complexity, and enables hand-foot coordinated braking.

[0005] The objective of this utility model can be achieved through the following technical solutions: A dual CBS proportional valve for all-terrain four-wheel vehicles includes a valve body. The valve body contains two sets of brake circuit components. The valve body has a foot brake input end and an input channel one that communicates with both brake circuit components. The valve body also has two mounting cavities for assembling the corresponding brake circuit components. Each brake circuit component includes a spring, a stepped valve core, and several seals. The valve core has a connector for the spring to abut against, and the other end of the spring abuts against the stepped valve core. The valve body also has a handbrake input end and a caliper output end that communicate with the corresponding brake circuit components. The valve body has an input channel two that communicates with the handbrake input end and an output channel two that communicates with the caliper output end. Each seal includes an outer ring abutment portion and an inner ring mounting portion. The stepped valve core has a sealing groove for mounting the inner ring mounting portion. The leading edge of the outer ring abutment portion curves outward and seals against the inner wall of the valve body. A sandwich groove exists between the outer ring abutment portion and the inner ring mounting portion.

[0006] In the aforementioned dual CBS proportional valve for all-terrain four-wheel vehicles, the handbrake input end also has a pressure relief hole communicating with the mounting cavity.

[0007] In the aforementioned dual CBS proportional valve for all-terrain four-wheel vehicles, the stepped valve core has radially inwardly opening flow grooves.

[0008] Compared with existing technologies, this dual CBS proportional valve for all-terrain four-wheel vehicles has the advantages of reducing installation costs and complexity, and improving performance. Attached Figure Description

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-3 As shown, this all-terrain four-wheel vehicle dual CBS proportional valve includes a valve body 1, which houses two sets of brake hydraulic circuit components. The valve body 1 has a foot brake input terminal 2 and an input channel 3 that communicates with the foot brake input terminal 2 and simultaneously connects to both brake hydraulic circuit components. The valve body 1 also has two mounting cavities 4 for assembling the corresponding brake hydraulic circuit components. Each brake hydraulic circuit component includes a spring 5, a stepped valve core 6, and several seals. A connector 7 is connected to the valve core for the spring 5 to abut against. The other end of the spring 5 abuts against the stepped valve core 6. The valve body 1 also has a handbrake input terminal 8 and a caliper output terminal 9 that communicate with the corresponding brake hydraulic circuit components. The valve body 1 has an output channel 3 that communicates with the handbrake input terminal 8. The input channel 10 and the output channel 11 are connected to the caliper output end 9. The seal includes an outer ring abutment part 12 and an inner ring mounting part 13. The stepped valve core 6 has a sealing groove 14 for the inner ring mounting part 13 to be installed. The front edge of the outer ring abutment part 12 is raised outward and abuts against the inner wall of the valve body 1. There is a sandwich groove 15 between the outer ring abutment part 12 and the inner ring mounting part 13. When the spring 5 is not compressed, the input channels 1 and 2 are not connected to the output channel 11. When braking is required, the stepped valve core 6 presses the spring 5, the spring 5 is compressed, and the input channels 1 and 2 are connected to the output channel 11. Under the action of the medium (oil), the vehicle brakes. The caliper output end 9 is connected to the brake caliper.

[0015] Preferably, the handbrake input terminal 8 also has a pressure relief hole 16 that communicates with the mounting cavity 4.

[0016] To elaborate further, the stepped valve core 6 has radially inwardly opening flow grooves 17 for the medium to pass through.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0018] Although this document frequently uses terms such as valve body 1, foot brake input end 2, input channel one 3, mounting cavity 4, spring 5, stepped valve core 6, connector 7, handbrake input end 8, caliper output end 9, input channel two 10, output channel 11, outer ring abutment part 12, inner ring mounting part 13, sealing groove 14, interlayer groove 15, pressure relief hole 16, and flow groove 17, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
