Field of the Invention The present invention relates to a buffer type brake master cylinder device for a vehicle, and more particularly to a buffer device for applying a force to a cylinder of a brake master cylinder. [Prior Art] One of the important functions of the car besides traveling is the hydraulic design of the brake system of the car that must be able to break the brakes. The main principle is to use the Pascal principle and the liquid incompressibility. . The specific structure is as shown in the figure--including the brake master cylinder (3), and the cylinder room (10) is arranged in the N room at the rear of the brake chest (3); the money is connected to the brake pedal of the brake pedal (5) (4) The end (9) of the brake lever (4) and the piston (1) are spaced apart from each other by a distance (m). When the brake pedal (5) has been depressed, the end (41) of the brake lever (4) is interlocked to fill The distance (D1), when the brake pedal (5) is continuously depressed, the end (41) of the brake lever (4) pushes the piston (1), and the brake oil and the brake oil are distributed to each wheel. The sub-pump, weaving pushes the fruit of each wheel and then does the oil. In the future, the film will have a braking effect on the brake drum or the brake disc. According to the prior art, although the end (41) of the brake lever (4) and the piston (1) are spaced apart from each other by a distance (D1), the process can be used as a buffer, so when the brake pedal is depressed, 5) With this spacing, the buffering distance can be used to buffer the brake oil in the brake master cylinder (3), so as to prevent the driver from directly resisting the resistance of the brake oil, and the driver's brake force is subjected to the instantaneous impedance. Makes the pedal touch Γ 2011· 201109208 Unsatisfactory, and the impedance is instantaneous in the brakes, which will lead to poor driving safety. However, the problem of the prior art is that the spacing (D1) buffer space enters the resistance space of the powerful brake oil by the space with almost no resistance, so although the distance between the two is used as a buffer, the impedance received by the force is still The formation of the drop is very large. Therefore, the buffering effect is limited, and the driver of the vehicle has a poor sense of pedaling on the pedal (5) of the pedal, thereby affecting driving safety. In order to improve the above-mentioned lack of vehicle control, although the vehicle is generally manufactured, there is a brake force (6) as shown in the first figure, and the wire booster (6) is interposed between the brake lever (4) and the brake car. · It can use the force to transmit the force. Although it can reduce the resistance of the job, the structure of the car multiplier (6) is complicated. In addition to the increase in the cost of the car and the cost of the car, it also increases the risk of failure. In turn, it affects driving safety. SUMMARY OF THE INVENTION In view of this, a buffer type brake master cylinder pump is designed to provide a cylinder space in the inner chamber of the rear of the brake master cylinder. In view of the problems of the prior art, the inventors believe that there should be a kind of The improved assembly includes a brake master; and a brake lever coupled to a brake pedal. The steel and piston of the vehicle are spaced apart from each other by two pitches. The invention is mainly for filling the elastic element in the space. Therefore, when the brake pedal is stepped on, the end of the brake lever is interlocked, and the lion is filled.

In the future, the film will brake the brake drum or the brake disc. Therefore, when the braking action is performed, there is a feeling of comfortable cushioning of the pedal, and a reaction force generated by directly pressing the space of the cylinder is reduced. This makes the pedal feel better, reduces the moment of braking, and improves the safety. The above effect can be achieved by simple installation, which greatly reduces the cost of the brake master pump installation. [Embodiment] Hereinafter, the apparatus, contents, and examples of the present invention will be described with reference to the accompanying drawings, which will enable the reviewing committee to have a further understanding of the present invention. Referring to the third figure, the present invention relates to a buffered brake main dish device for a vehicle, comprising: a brake master cylinder (3): • a pressurization space is arranged in the inner chamber of the rear of the brake master cylinder (3) ( 30); the red space (30) is provided with a piston (1). The type of the brake main (3) is not the same as the piston (1) described above, and the piston (1) is used as the initial source (referred to as a single circuit), and may also be as shown in the tenth figure. The second piston (10) is axially coupled to the end of the piston (1), and the second piston (10) is axially pushed by the piston (1), and the second piston (10) is used as a material-initial source of the circuit (the piston It is called a double circuit when it is placed in a loop with the first piston. 201109208 is available for connection to the 煞 姊 姊 , , , , , , , , , 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 (D1) 'The invention is characterized in that an elastic element (2) is filled in the spacing (di). The elastic member (2) may be a transversely compressed elastic phthalocyanine (' ̄ ̄ ^ (10) _ig)'. The elastic member (2) allows the force transmission to be more quasi-continuous. Since the end (41) of the shovel dust rod (4) is -[shaped, it is possible to stably accommodate the portion of the elastic member (2) in the [shaped space, which also forms an elastic cyanine seat. Further, the compression spring (compressi〇n spring) of the present invention is gradually opened from the end face (9) close to the end face of the piston (1) to the brake lever (4). By the fact that the end face of the piston (1) is thinner, so that it is easier to be compressed, the elastic modulus and the thickness and shape of the elastic member (2) can be adjusted according to the damping required by the present invention. The open end is mainly for enabling the elastic crystal to be stably accommodated in the dome-shaped space. Please refer to the fourth figure.
