The present invention relates to a brake master cylinder for a continuous brake system, in particular to a brake master cylinder for a continuous brake system suitable for locomotives.

In order to improve the safety of locomotive riding, it is necessary to develop an interlocking brake system to effectively shorten the braking distance, especially the disc brake system equipped with the front and rear brake systems. The interlocking brake must be designed to maintain good mechanism action, so that the interlocking brake can operate normally, and at the same time It can also take into account the cost of control. The conventional technology is the interlocking brake system announced in Taiwan Patent Publication No. TW I653169. Please refer to Figure 17, which is a partial cross-sectional view of the conventional interlocking brake system. As shown in the figure, the conventional interlocking brake system mainly includes a first brake master cylinder 91, a second brake master cylinder 92, a first brake caliper 93, a second brake caliper 94, a brake wire 98, and a first brake caliper. The brake oil pipe 96 and a second brake oil pipe 97, the first brake master cylinder 91 includes a first cylinder 911, a first brake lever 912 and an actuating rod 915.

The actuating rod 915 is mounted on the first pivot point 9111 of the first cylinder 911, and the actuating rod 915 can push a first plunger 913 so that the first cylinder 911 sends a hydraulic pressure to the first brake caliper 93. The first brake lever 912 is installed on the second pivot point 9112 of the first cylinder 911, and the rocker arm 925 is installed on the third pivot point 9221 of the second cylinder 921.

The brake wire 98 includes a first sleeve 981 and a The inner wire 982 in a sleeve 981 transmits the force exerted by the first brake lever 912 to the rocker arm 925. One end of the first sleeve 981 abuts against the actuating rod 915 and the other end abuts against the second cylinder 921.

When the first brake lever 912 is operated, the inner cable 982 pulls the rocker arm 925 with all the force exerted by the first brake lever 912, and the reaction force of the first sleeve 981 pushes the actuating rod 915 to make the first brake caliper 93 and the second brake The actuation of the caliper 94 generates braking force. The brake wire 98 is arranged between the first brake master cylinder 91 and the second brake master cylinder 92. The path of the brake wire 98 is often bent. Since the brake wire 98 must bear all the force exerted by the first brake lever 912, The brake wire 98 must have a certain strength to avoid breakage, and the opposite first sleeve 981 must also have sufficient rigidity to avoid bearing the wire reaction force and excessive compression to make the hand feel soft, but the sleeve with sufficient rigidity is bending At this time, force will be applied to the actuating rod 915, so that the first plunger 913 is urged by the actuating rod 915 when the first brake lever 912 is not actuated, causing problems such as the pressure of the first brake caliper 93 that cannot be released.

This is the reason for the inventor. Based on the spirit of active invention, he eagerly thought of a brake master cylinder for the interlocking brake system that could solve the above-mentioned problems. After several studies and experiments, the invention was finally completed.

The main purpose of the present invention is to provide a brake master cylinder for the interlocking brake system. By changing the configuration of the first operating lever, the actuating lever and the brake wire, the brake wire can be used in addition to maintaining the original interlocking braking performance. With better durability, it can also take into account the pressing feel of the rider when operating the brake, so as to enhance the service life and operability of the interlocking brake system.

To achieve the above objective, the brake master cylinder for the interlocking brake system of the present invention is one of the first brake master cylinders in the interlocking brake system, and includes a first cylinder, a first brake lever, an actuating rod, and a Brake wire, the first cylinder has a first oil chamber, a first plunger and a first spring, the first A brake lever is pivotally connected to the first cylinder body, and is provided with a rotating shaft.

On a cylinder body, one end of the actuating rod has a first pushing portion for pushing the first plunger. The brake wire includes a first sleeve and an inner wire passing through the first sleeve. One end of the tube is fixed on the actuating rod. The utility model is characterized in that one end of the inner wire is fixedly arranged on a fixed point of the actuating rod, and the inner wire section between the first sleeve and the fixed point surrounds the rotating shaft.

Furthermore, the brake master cylinder for the interlocking brake system designed in the present invention is one of the first master cylinders in the interlocking brake system, and includes a first cylinder block, a first brake lever, and an actuating rod. And a brake wire, the first cylinder has a first oil chamber, a first plunger and a first spring, the first brake lever is pivotally connected to the first cylinder, and is provided with a rotating shaft, and the actuating rod is pivotally connected On the first cylinder body, one end of the actuating rod has a first pushing part for pushing the first plunger, the brake wire includes a first sleeve and an inner wire passing through the first sleeve, One end of the first sleeve is fixed on the first cylinder. The utility model is characterized in that one end of the inner wire is fixedly arranged on a fixed point of the actuating rod, and the inner wire section between the first sleeve and the fixed point surrounds the rotating shaft.

With the above-mentioned design, since the shaft pulls the inner cable using the pulley relationship when the present invention performs force transmission, the brake cable does not need to use a higher rigid brake cable sleeve specification to achieve the effect of continuous braking. The force exerted on the actuating rod caused by the bending of the path of a casing in the assembly layout is also relatively small, which does not affect the normal operation of the actuating rod, so it will not cause problems such as the failure of the pressure of the first brake caliper to be released.

In order to construct a perfect interlocking brake system, in addition to the above-mentioned first brake master cylinder, the present invention can also connect the first brake master cylinder with a second brake master cylinder so that both wheels have disc brake functions. Braking system.

Therefore, when the first brake lever is continuously pressurized, the first plunger will exert a reaction force on the actuating rod to resist the rotation of the actuating rod. At this time, the shaft of the first brake lever will move away from the actuating rod, so that the rocker arm will push the first brake lever. The two plungers allow the second brake master cylinder to generate a hydraulic pressure for the second brake calipers to actuate to produce interlocking braking.

The above-mentioned interlocking brake system may further include a first brake caliper and a second brake caliper. The first brake caliper is connected to the first cylinder by a first brake pipe, and the second brake caliper is connected to the second by a second brake pipe. Cylinder block.

When the second plunger 23 moves, the second spring is compressed, and part of the hydraulic oil in the second oil chamber will be pushed out of the second cylinder 21 to make the second brake assembly Pump 2 generates an oil pressure. The second brake lever 22 and the rocker arm 25 are pivotally connected to the second cylinder 21 at the third pivot point 221 at the same time. Therefore, when the rocker arm 25 rotates, the second plunger 23 will be pushed; and when the second brake When the lever 22 is rotated, the rocker arm 25 will be pushed.
