When the car engine is in the forward position, the distance between the rear wheel and the pump will be greater than the distance between the front wheel and the pump. Thus, when the driver starts the brakes, the rear wheel brakes will be slower than the front wheel brakes. In this situation, if the automobile is using the rear wheel transmission structure, when the driver drives the brake, the front wheel will generate braking force and the rear wheel will continue to output power, which will cause the automobile to slip.

A second elastic member 42, such as a compression spring, is disposed in the second chamber 41, and the second elastic member 42 is located between the lower end of the second piston 40 and the lower wall surface 410 of the second chamber 41. The lower wall surface 410 of said second chamber 41 is formed a second hole 411, and the second hole 411 is provided with a second output duct 413, so that the second output pipe 413 can output the hydraulic fluid inside the second chamber 41 to the front wheel brake 51, and to drive the front wheel brake 51 to generate a braking force.

    [0019] As shown in Figs. 1 to 3, said second chamber 41 is provided with a second replenishing device 43, the second replenishing device 43 can be disposed on the outer side of the casing 2, and the second replenishing device 43 can be made of plastic or other light-transmissive material, so that the user can observe the amount of hydraulic fluid of the second replenishing device 43.

The second fluid storage tank 431 is provided with a second plug 432, and the hydraulic fluid in the second fluid storage tank 431 can be replenished or replaced through the second plug 432. A gas temporary storage space S2 is disposed in the second fluid storage tank 431, and said second connection duct 414 is formed at a highest water level of the hydraulic fluid of the second chamber 41. In this way, the air bubbles generated from the second chamber 41 can be transported to the gas temporary storage space S2 of the second fluid storage tank 430 through the second output duct 413 and the second regulating valve 430 to maintain the quality and temperature of the hydraulic fluid in the second chamber 41.

    [0020] The first piston 30 of the first pump mechanism 3 and the second piston 40 of the second pump mechanism 4 may be provided in different sizes to provide different braking forces. As shown in Figs. 1 to 3, since the time for starting the front wheel brake 51 is later than the time for starting the rear wheel brake 50, in order to make the braking force of the front wheel brake 51 larger than the braking force of the rear wheel brake 50, the size D2 of said second piston 40 must be larger than the size D1 of the first piston 30, so that, when the pushing block 10 is pressed to the second piston 40, the second piston 40 can output more hydraulic fluid than the first piston 30, and the hydraulic brake force P2 of the second pump mechanism 4 can be greater than the hydraulic brake force PI of the first pump mechanism 3

    [0021] It is worth mentioning that said first replenishing device 33 of the first pump mechanism 3 and said second replenishing device 43 of the second pump mechanism 4 may be the same replenishing device, and the hydraulic fluid of the first chamber 31 of the first pump mechanism 3 and the hydraulic fluid of the second chamber 41 of the second pump mechanism 4 are simultaneously supplied by only one replenishing device.

    [0022] In addition, said first pump mechanism 3 may not be provided with the first replenishing device 33, and said second pump mechanism 4 may not be provided with the second replenishing device 43, as long as sufficient hydraulic fluid is stored in the first chamber 31 and the second chamber 41, the same effect can be obtained.

    [0023] As shown in Figs. 1, When the driver activates the brake operating element A1, the driving device 1 will drive the pushing block 10 to press the first piston 30 to move downward. At this time, the first elastic member 32 is compressed, and the first chamber 31 outputs the hydraulic brake force PI downward to make the rear wheel brake 50 generate the braking force. As shown in Figs. 2, after the pushing block 10 moves a separation distance d1, the second piston 40 will be synchronously pressed to move downward together. At this time, the second elastic member 42 is compressed, and the second chamber 41 outputs the hydraulic brake force P2 downward to make the front wheel brake 51 generates the braking force. In this way, a time difference between rear wheel brake 50 and front wheel brake 51 can be achieved by performing one braking action, and through the special size design of the first piston 30 and the second piston 40, the second piston 40 started later can instantaneously output a hydraulic brake force greater than the first piston 30, to let the front wheel braked later have a larger braking force than the rear wheel.

    [0024] The present invention can provide at least one set of time difference hydraulic brake device on the vehicle according to requirements. As shown in Fig. 4, the present invention can be provided with two sets of time difference hydraulic brake devices B1, B2, which are respectively connected with two brake operating elements A1, A2. The first output ducts 313 of the first pump mechanisms 3 of the two time difference hydraulic brake devices B1, B2 are connected together by a connection valve 315, the hydraulic fluid in each of the first chamber 31 can be output to the rear wheel brake 50 at the same time or separately; the second output ducts 413 of the second pump mechanisms 4 of the two time difference hydraulic brake devices B1, B2 are connected together by a connection valve 415, the hydraulic fluid in each of the second chamber 41 can be output to the front wheel brake 51 at the same time or separately. In this way, with a plurality of time difference hydraulic brake devices, even if one time difference hydraulic brake device suddenly breaks down, the brake function of the vehicle will not be invalid, so as to improve driving safety.

    [0025] In summary, the present invention utilizes an innovative brake structure to realize the time difference braking technique in which the rear wheel preferentially activates the braking action, to prevent the vehicles from slipping or spillover. Evidently this invention has tangible benefits and tallies with progressiveness and novelty demanded by patent laws.
