The hydraulic delay proportioning distribution linkage system provided in the present invention can be applied in motorcycles, automobiles or other machines in need of front and rear braking and proportioning braking. Now the hydraulic delay proportioning distribution linkage system is introduced by taking the motorcycle as an example.

Fig. 1 is a perspective diagram of a hydraulic delay proportioning distribution linkage system provided in an example of the present invention; Fig. 2 is a sectional diagram of the hydraulic delay proportioning distribution linkage system in Fig. 1. Referring to Fig. 1 and Fig. 2, the hydraulic delay proportioning distribution linkage system provided in the present example comprises a proportion regulating mechanism, a delay mechanism and a valve body 1; the valve body 1 is internally provided with a rear braking input channel 2, a first output channel 3 and a second output channel 4; the first output channel 3 and an inlet end of the second output channel 4 both communicate with the rear braking input channel 2; the proportion regulating mechanism is provided in the first output channel 3, so as to regulate a ratio of a hydraulic pressure output from the first output channel 3 to a hydraulic pressure from the second output channel 4; and the delay mechanism is provided in the second output channel 4, so as to delay output of the hydraulic pressure from the second output channel 4.

In the above, the proportion regulating mechanism and the delay mechanism can have various structural forms, for example, the proportion regulating mechanism and the delay mechanism both can be regulating valves, regulating a hydraulic liquid amount of an output end of the first output channel, and delaying output of braking power of the output end of the second output channel.

In the hydraulic delay proportioning distribution linkage system provided in the present example, the proportion regulating mechanism is provided in the first output channel 3, and the delay mechanism is provided in the second output channel 4. A user, when using the hydraulic delay proportioning distribution linkage system of the present example to

Petition 870160079484, of 12/27/2016, p. 16/28 / 13 brake the motorcycle, uses the delay mechanism to delay output of a hydraulic pressure of a front brake, allowing a rear brake to brake first, and then uses the proportion regulating mechanism to regulate a ratio of a hydraulic pressure of the rear brake to the hydraulic pressure of the front brake, so that the motorcycle running at a high speed can be braked relatively stably and quickly, meanwhile a braking distance is also shortened, reducing the probability of occurrence of drifting, sidesliping or turnover of the motorcycle running at a high speed when being braked.

As shown in Fig. 2, on the basis of the above-mentioned example, further, the delay mechanism comprises a delay piston part and a delay spring 15; the delay piston part and the delay spring 15 are provided in the second output channel 4; the delay spring 15 is used to make the delay piston part have a tendency of moving towards the rear braking input channel 2, so as to make the delay piston part close the inlet end of the second output channel 4.

Further, the proportion regulating mechanism comprises a proportioning piston rod 6, a proportioning piston head 5 and a proportioning spring 7; the output end of the first output channel 3 is provided with a proportioning sealing ring 8; the proportioning piston rod and the proportioning spring 7 are provided in the first output channel 3; the proportioning piston rod 6 passes through the proportioning sealing ring 8; one end of the proportioning piston rod 6 close to the output end of the first output channel 3 is provided with the proportioning piston head 5; the proportioning spring 7 is used to make the proportioning piston head 5 have a tendency of moving towards the output end of the first output channel 3, so that the proportioning piston head is spaced from the proportioning sealing ring 8, and meanwhile has a gap with an input end of the first output channel 3, leaving the input end of the first output channel 3 open.

In the above, an annular block 9 is provided on the proportioning piston rod 6, and the annular block 9 and the proportioning piston head 5 are located at both sides of the proportioning sealing ring 8; the proportioning spring 7 has one end abutting against the annular block 9, and the other end connected with the rear input channel; and when the

Petition 870160079484, of 12/27/2016, p. 17/28 / 13 proportioning spring 7 is in an initial state, the annular block 9 and the proportioning piston head 5 are both spaced from the proportioning sealing ring 8.

In addition, an elastic force of the proportioning spring 7 is less than that of the delay spring 15.

Besides, preferably, a ratio of the hydraulic pressure output from the second output channel 4 to the hydraulic pressure output from the first output channel 3 is 6 ~ 7: 4 ~ 5. Then according to setting of various parameters of the brake system, a ratio of braking torques of the front and rear wheels can be set to 6 ~ 7: 4 ~ 3.

Of course, the user can adjust sizes of the rear braking input channel 2, the first output channel 3 and the second output channel 4, and areas of end faces of the proportioning piston head 5, the delay piston head 13 and the delay sealing ring 14, and further adjust the ratio of the hydraulic pressure output from the second output channel 4 to the hydraulic pressure output from the first output channel 3.

When the rear braking input channel 2 inputs a predetermined hydraulic pressure, at this time the delay piston part seals the front braking output channel, while at this time the first output channel 3 is in a pass-through state, and the rear brake brakes. When the input hydraulic pressure of the first output channel 3 is greater than the elastic force of the proportioning spring 7, the amount of the hydraulic fluid flowing from the first output channel 3 into a rear-brake braking caliper component is increased, at this time the hydraulic fluid flowing into the rear-brake braking caliper component has a counterforce on the proportioning piston head 5, so that the proportioning piston head 5 gradually fits the proportioning sealing ring 8, and further seals the first output channel 3.

When the input hydraulic pressure in the rear braking input channel 2 is greater than the elastic force of the delay spring 15, a spacing is created between the delay piston portion and the input end of the second output channel 4, so as to make the second output channel 4 be in a pass-through state, at this time, the front brake starts to brake.

When the hydraulic pressure in the rear braking input channel 2 is again increased, the increased hydraulic pressure will instantly push the proportioning piston head, so that a

Petition 870160079484, of 12/27/2016, p. 18/28 / 13 spacing is created between the proportioning piston head 5 and the proportioning sealing ring 8, causing some hydraulic fluid to flow into the rear-brake braking caliper component, thus the ratio of the hydraulic pressures of the front and rear brakes is regulated, enabling the motorcycle to be more stable during the braking process. In this way, the user, just by operating the rear brake, can complete the braking of the motorcycle in a state of highspeed running. The operation is simple and the safety performance is high.

As shown in Fig. 2, on the basis of the above-mentioned example, further, the delay piston part comprises a delay piston rod 16, a delay piston head 13, a delay sealing ring 14 and a delay piston return spring 17; the delay piston head 13 is provided at one end of the delay piston rod 16; the delay piston rod 16 is sleeved with the delay sealing ring 14. Of course, in order to ensure sealability of the delay sealing ring 14 and facilitate installation of the delay spring 15, a delay sealing ring washer 29 is provided on the delay sealing ring 14; moreover, the delay sealing ring 14 is spaced from the delay piston rod 16 and a side wall of the second output channel 4 respectively, and the inlet end of the second output channel is provided with an annular protruding platform; the delay piston rod 16 is sleeved with the delay spring 15, one end of which is abutting against the delay sealing ring washer 29 on the delay sealing ring 14, and the other end of which is connected with the second output channel 4, so as to make the delay sealing ring 14 abut against the annular protruding platform; the delay piston return spring 17 is provided at the other end of the delay piston rod 16, so as to make the delay piston head 13 and the delay sealing ring 14 have a spacing therebetween; and an elastic force of the delay spring 15 is greater than that of the delay piston return spring 17.

When a little braking power is input into the rear braking input channel 2, the second output channel 4 and the first output channel 3 are in a pass-through state. Since the hydraulic pressure is quite low at this time, the problem of too much front and rear braking powers will not be caused. When the hydraulic pressure of the input channel 2 reaches the predetermined hydraulic pressure, ie is greater than the elastic force of the delay piston return spring 17 and less than the elastic force of the delay spring 15, the delay piston head 13 starts to move, until the delay piston head 13 is in sealing contact with the delay sealing

Petition 870160079484, of 12/27/2016, p. 19/28 / 13 ring 14, sealing the second output channel 4, and by this time the first output channel 3 is still in the pass-through state, i.e. the braking time of the front brake can be delayed.
