referring to fig. 1 to 3, the diameter D1 of the first chamber 31 of the first piston 30 of the first pump mechanism 3 of the previous embodiment is different from the diameter D2 of the second chamber 41 of the second piston 40 of the second pump mechanism 4. The diameter D2 of the second chamber 41 is larger than the diameter D1 of the first chamber 31, so that the second pump mechanism 4 can rapidly generate the second brake braking force when the driving mechanism 1 drives the first pump mechanism 3 in a very short time difference while adding and simultaneously driving the second pump mechanism 4, and the brake oil pressure braking force P2 of the second pump mechanism 4 is larger than the brake oil pressure braking force P1 of the first pump mechanism 3 in a very short time. The brake speed of the front wheel brake is slightly higher than that of the rear wheel brake, so that the front wheel which starts to brake later has larger brake force than the rear wheel which starts to brake earlier.
As shown in fig. 1 to 3, in the present invention, the first pump means 3 is provided with the first oil supply device 33, and the second pump means 4 is provided with the second oil supply device 43, so that after the technical problems are overcome, the first oil supply device 33 and the second oil supply device 43 are made into a single oil supply device to simultaneously supply the hydraulic oil to the first chamber 31 of the first pump means 3 and the hydraulic oil to the first chamber 41 of the second pump means 4, respectively.
As shown in fig. 1 to 3, the present invention can also achieve the purpose of braking force with time difference by not providing the first oil supply device 33 in the first pump mechanism 3 and not providing the second oil supply device 43 in the second pump mechanism 4, and by storing a sufficient amount of hydraulic oil in the first chamber 31 of the first pump mechanism 3 and a sufficient amount of hydraulic oil in the first chamber 41 of the second pump mechanism 4.
As shown in fig. 2, when the rider or driver actuates the brake operating assembly a1, the driving mechanism 1 is actuated to generate kinetic energy to drive the first piston 30 of the first pump mechanism 3 to move downward and compress the first restoring member 32, so that the hydraulic oil in the first chamber 31 starts to output the first brake force to the rear wheel brake 50 via the first output pipe 313, and the rear wheel brake 50 generates brake force. Referring to fig. 3, the time difference between the distances of the first piston 30 of the first pump mechanism 3 reaching the set displacement is added to and simultaneously pushes the second piston 40 of the second pump mechanism 4 to generate the displacement, and the second brake braking force is output to the front wheel brake 51. Thus, a braking action of a rider or a driver is performed, and a braking action of a time difference is generated between the rear wheel brake 50 and the front wheel brake 51 by the first braking force and the second braking force of the time difference generated at the beginning of the first pump mechanism 3 and the second pump mechanism 4. As mentioned above, since the diameter D2 of the second chamber 41 is larger than the diameter D1 of the first chamber 31, when the driving mechanism 1 drives the first pump mechanism 3 to drive the second pump mechanism 4 within a very short time interval, the second pump mechanism 4 can rapidly generate the second brake force, and the brake oil pressing power P2 of the second pump mechanism 4 is larger than the brake oil pressing power P1 of the first pump mechanism 3 within a very short time interval, so that the second brake force generated by the second pump mechanism 4 is larger than the first brake force generated by the first pump mechanism 3, and the brake speed of the front wheel brake is slightly higher than the brake speed of the rear wheel brake, and the front wheel which starts to brake later has a larger brake force path than the rear wheel which starts to brake earlier.
The invention is characterized in that one or two groups of time difference brake devices are arranged on vehicles with handles such as bicycles, locomotives, electric vehicles and the like or other vehicles. As shown in fig. 4, the present invention is configured to provide a first set of the jog brake devices B1 and a second set of the jog brake devices B2, which are respectively driven by the brake operating assembly a1 and the second brake operating assembly a2, and allow the first output pipe 313 of the first piston 30 of the first pump mechanism 3 of the first set of the jog brake devices B1 and the first output pipe 313 of the first piston 30 of the first pump mechanism 3 of the second set of the jog brake devices B2 to be communicated by the three-way valve 315, so as to respectively or simultaneously output the first brake force to the rear wheel brake 50 of the vehicle; the second output pipe 413 of the second piston 40 of the second pump mechanism 4 of the first set of the differentially operated brake device B1 and the second output pipe 413 of the second piston 40 of the second pump mechanism 4 of the second set of the differentially operated brake device B2 are communicated by the three-way valve 415 to output the second brake braking force to the front wheel brake 51 of the vehicle, respectively or simultaneously. The purpose is to improve the driving safety and reliability by using two sets of time difference brake devices B1 and B2 as the function of safety assurance.
In summary, the present invention utilizes a braking action of a rider or a driver to generate a braking force with a time difference between the first pump mechanism 3 and the second pump mechanism 4 through the driving mechanism 1, so that for various vehicles driven by a rear wheel, the rear wheel brake generates a certain braking force for the rear wheel in advance to achieve the purpose of deceleration, and then the time difference of the front wheel brake generates a larger braking force for the front wheel than for the rear wheel, as mentioned above, the structural and technical characteristics that the diameter D2 of the second chamber 41 is larger than the diameter D1 of the first chamber 31 are taken as the basis, so that the braking efficiency, safety and stability of the vehicle can be improved. However, the hydraulic type time difference brake device is not limited to the pattern and the usage of the invention, and any suitable changes or modifications by those skilled in the art should be considered as not departing from the scope of the invention.
