Abstract

This invention provides a linking dual disk brake hydraulic systems for the motorcycle's front and rear wheels with high brake performance and stability. The main point is a distributed hydraulic driving device. When holding the first level, the brake fluid is first driven to the disk brake of the rear wheel. Then the brake fluid is driven by the first and second pistons to the disk brake of the front wheel through another hydraulic pipe. Using this hydraulic system, the high performance disk brakes can be applied to both the rear and front wheels. Further, avoiding the front wheel stoppage before the rear wheel stoppage, the brake power of the front wheel is delayed by the hydraulic circuits. Therefore, the brake power and stability of the motorcycle can be increased.

The only difference is that the distribution driving device 7 is provided with a second recovery element 78 only in the second compression space 732 of the second cylinder hole 73, and there is no recovery in the first compression space 722 of the first cylinder hole 72. The components are arranged; in this way, when the first and second tie rods 6 1 and 6 2 are pulled, the operation mode of causing oil pressure to pass through the distribution driving device 7 to cause braking of the front and rear wheels is the same as the previous embodiment. Therefore, the linked brake system 6 of this embodiment can also achieve the same as the previous embodiment. The disc brake system is used at the front and rear stoppers 6 5 and 6 6 to improve the braking performance of the locomotive, and can cause the brake pressure of the front wheels. Rear wheel The delay of the vehicle is to maintain the stability of the locomotive braking; however, when the forces of the first and second levers 6 1 and 6 2 are released, the second piston 75 returns by the elastic recovery effect of the second recovery element 78, and the first One piston 74 is backed up by the oil pressure originally applied to the front stopper 65, and pushed back through the flow hole 7 51 of the second piston 75, because this embodiment is more than the aforementioned interlocking brake system 2. The setting of the first recovery element 37 can be eliminated, so the manufacturing process can be simplified and the manufacturing cost can be saved.

Page 12 470719 V. Explanation of the invention (ίο). Based on the above description, the present invention is compared with the conventional knowledge. As can be seen, the present invention does have the following effect enhancement: 1. The interlocking brake system of the present invention distributes the setting of the driving device, so that the brake oil pressure output by pulling the first lever can be directly driven on the one hand-the rear stopper achieves the function of braking the rear wheels, on the one hand The pressure of the first and second pistons is converted into another oil output, and the front stopper can be indirectly driven to achieve the braking effect of the front wheels. At the same time, the brakes of the front and rear wheels are hydraulically operated. The power transmission is completed by type, so the front and rear stoppers can be designed as a disc brake system with high sensitivity, so the braking performance of the locomotive can be improved. 2. Continuing from the previous description, due to the arrangement of the distributed braking device of the interlocked braking system of the present invention, when the first lever is pulled to output the brake oil pressure, the braking force is first generated on the rear wheel that is subjected to a large load, and waits for the first time. When a piston moves against the second piston, and the second piston is pushed further, it will start to brake the front wheels. That is to say, the invention can cause the brake pressure of the front wheels to be delayed compared to the rear wheels when the brakes are linked, thereby avoiding the front wheels. Stop first and keep the body balanced to ensure safe riding. In summary, the locomotive braking system of the hydraulic type front and rear dual disc brakes of the present invention can effectively achieve the effect of improving the braking effect and the stability of the brake through the setting of the distributed driving device. Therefore, the present invention is one Progressive design, but no similar or similar items have been disclosed in the city, and it has already met the patent requirements for novelty, and applied in accordance with the provisions of the Patent Law. However, the above are only the preferred embodiments of the present invention. Therefore, the equivalent structural changes for the application of the description of the present invention and the scope of patent application
