Description

Linked brake system

The invention relates to a linkage braking system, in particular to a linkage braking system suitable for a locomotive.

The linked brake system shown in Taiwan Patent No. I301462 is a design of a linked brake system that can operate two drum brakes simultaneously by applying only one brake wire. This design is fixed because the pivot point in the linkage mechanism is fixed. The first balance plate member and the second balance plate member are relatively rotated by the first pivoting portion and the second pivoting portion, so that when the two brake wires of the two drum brake systems are simultaneously controlled, The ratio is linear, that is, if the first brake wire is applied to the first brake wire, the braking force generated by the first drum brake device (ie, the rear wheel of the locomotive) is controlled by the second drum type. The brake force generated by the brake device (ie, the front wheel of the locomotive) is increased or decreased in equal proportions.

Please refer to FIG. 1 , which is a comparison diagram of the braking force of the brake wire of the present invention and Taiwan Patent No. I301462, wherein the X axis represents the force applied by the first brake wire, and the Y axis represents the force applied by the second brake wire, Taiwan Patent No. I301462 The force application is shown in line A of Figure 1. When the force of the first brake wire is with force Increase, because of its linkage relationship, its relative spacing is linear, so the force of the second brake wire at the linkage end increases according to a certain ratio. Generally, for the braking system of the two-wheeled vehicle, the first drum-type braking device controls the braking of the rear wheel of the locomotive, and the second drum-type braking device controls the front wheel of the locomotive, and the greater the force applied to the brake wire, the more the braking force generated. Large, so the locomotive that controls the braking system will increase the braking force of the rear wheel of the locomotive and the braking force of the front wheel of the locomotive. However, if the force of the brakes applied to the front wheels is too large, it is prone to slipping out of control. In order to increase the safety of the linkage system, it is necessary to improve the above-mentioned defects.

Because of this, in the spirit of actively inventing and creating, we have thought of a "linking brake system" that can solve the above problems, and finally completed the present invention after several research experiments.

First drum The brake device 3 has a first drum base 30 and a first brake arm 31 and a first hole 32 disposed on the first drum base 30. When the first brake arm 31 is actuated, the first The drum brake device 3 generates a braking action. The second drum brake device 4 has a second drum base 40 and a second brake arm 41 and a second hole portion 42 disposed on the second drum base 40. Similarly, when the second brake is used When the arm 41 is actuated, the second drum brake device 4 generates a braking action. In the present embodiment, the first drum brake device 3 is disposed on the rear wheel of the locomotive, and the second drum brake device 4 is disposed on the front wheel of the locomotive.

As shown in FIGS. 3 and 4, the linkage mechanism includes a base 82, a curved rod 81 having a curved surface 813, a bracket 85 and two rolling members 83, 84. The two ends of the curved rod 81 have a first hole 811 and a second hole 812. The two ends of the base 82 respectively have a third hole 821 and a fourth hole 822. The curved rod 81 and the base The intermediate ends of the 82 are attached to the brackets 85. The two rolling members 83, 84 are sleeved on the brackets 85 and abut the surfaces of the curved rods 81 and the base 82, respectively.

In this embodiment, the end of the curved rod 81 has an arc-shaped plane, and the two ends of the curved rod 81 are in a straight plane. The base 82 is rectangular, and therefore, the curved shape of the curved rod 81 is curved. The face 813 will interfere with the surface of the pedestal 82. As the curved bar 81 changes at a different angle than the pedestal 82, the curved surface 813 will have a different positional contact change. In addition, the two rolling members 83, 84 and the bracket 85 can combine the curved rod 81 and the base 82 to avoid detachment. In the present embodiment, the rolling members 83, 84 are rollers.

The plurality of sleeves includes a first sleeve 52, a second sleeve 53, and a third sleeve 62.

In addition, the two ends of the second brake wire 61 are respectively connected with the second hole 812 of the curved rod 81 and the second brake arm 41, and the second brake wire 61 is covered by the third sleeve 62.

5 is a schematic plan view showing the operation of the interlocking brake system according to the first preferred embodiment of the present invention. When the first brake lever 11 is pressed and pulled, the first brake wire 51 will pull the first brake arm 31 to make the first drum. The brake device 3 generates a braking action, that is, the rear wheel of the locomotive generates a braking action. At this time, since the first sleeve 52 and the second sleeve 53 are under pressure, the first hole 811 of the curved rod 81 and the base 82 are pressed. The third hole 821 is zoomed in, that is, the two rolling members 83 and the bracket 85 slide to the left (ie, the first hole 811 of the curved rod 81 and the third hole 821 of the base 82), thereby causing the curved rod 81 to be moved. The second brake wire 61 is pulled to activate the second brake arm 41, and the second drum brake device 4 follows the braking action, that is, the front wheel of the locomotive also generates a braking action.

Since the curved rod 81 is in contact with the surface of the base 82 by its curved surface 813, with the angle between the curved rod 81 and the base 82, The curved surface 813 of the curved rod 81 has a different change from the abutment contact of the surface of the base 82.

For example, the force applied by the first brake wire (X-axis) increases with the force, and the force applied by the second brake wire (Y-axis) is just higher than the force applied by the first brake wire (X-axis), but as the force increases, After passing the turning point, the force applied by the second brake wire (Y-axis) is lower than the force applied by the first brake wire (X-axis), so the second brake wire does not have excessive force, which ensures the second drum. The braking force of the front wheel of the locomotive that is used by the brake device is not too large, that is, the slipping phenomenon does not occur.

A second brake lever and the second brake arm 41 are respectively connected. In addition, the two ends of the fourth sleeve 72 are respectively sleeved between the second fixing frame 22 and the second hole 812 of the curved rod 81. In the present embodiment, the fourth sleeve 72 is also made of a material having moderate rigidity.

Thereby, when the first brake lever 11 is pressed and pulled, as described above, both the first drum brake device 3 and the second drum brake device 4 generate a braking action. When the second brake lever 21 is pressed and pulled, the second brake wire 71 will pull the second brake arm 41 to make the second drum brake device 4 The brake pedal operation, at this time, the curved lever 81 does not pull the first brake wire 51, that is, the first drum brake device 3 does not generate any braking action.
