Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stopper device for a brake master cylinder in a four-wheeled vehicle.

[0002]

[Prior art and its problems]

 In the engine room of a four-wheeled vehicle, a brake master cylinder that interlocks with the brake pedal is installed.However, when the brake pedal is depressed, this brake master cylinder has insufficient rigidity on its mounting surface. Since it moves about 5 to 10 mm to the front side (the brake pedal will escape by that amount), a time loss will occur in the braking time of the car, adversely affecting the braking force, and braking When I stepped on the pedal, I felt a spongy feeling and the brake feeling was not good.

The present invention has been made in view of the above conventional problems, and an object thereof is to prevent the protrusion of the brake master cylinder from being prevented, thereby shortening the braking time, and thus the braking force. It is an object of the present invention to provide a stopper member for a brake master cylinder that can be transmitted more accurately to improve safety and can provide an excellent brake feeling with a “click” when the brake pedal is depressed.

[0004]

[Means for solving problems]

 To this end, the present invention provides a stopper body having a mounting portion having a mounting hole for a mounted body in an engine room, a block portion integrally connected to the mounting portion, and a brake in the block portion. The structure is characterized in that it is provided with a stopper protrusion that is provided so as to project from a surface facing the moving direction of the master cylinder and that prevents the brake master cylinder from moving to the front side when the brake pedal is depressed.

[0005]

[Action]

 The stopper device having the above-described structure is provided with a member close to the brake master cylinder in the engine room of a four-wheeled vehicle, preferably on the outer surface of the strut house, with bolts to the mounting holes of the mounting portion and, if necessary, with this. It can be attached firmly using the attached mounting stay that also serves as the brake master cylinder so that the protruding portion of the stopper comes into contact with the brake master cylinder. Then, in this state, even if the brake petal is stepped on and the brake master cylinder moves (projects) toward the front side in response to this, the brake master cylinder is pressed by the pressing surface of the stopper protrusion and moves (projects). ) Is blocked.

【Example】

 An embodiment will be described below with reference to the drawings. FIG. 1 is an overall perspective view, FIG. 2 is a perspective view seen from two directions of the same, and FIG. , FIG. 4 is an exploded perspective view showing a mounted state, FIG. 5 is a schematic view of a used state, and FIG. 6 is an explanatory view of the used state. In these figures, the stopper body 10 is preferably a light metal such as aluminum. The stopper body 10 is an integrated product made of a material, and the stopper main body 10 has a vertically-long rectangular mounting portion 11 having two vertically-long bolt holes 12 for a mounted body (strut house) A in the engine room, and the mounting portion 11 It has a block portion 13 continuously provided in a substantially L shape, and two columnar stopper protrusions are provided on the same axis as the moving (protruding) direction of the brake master cylinder B in the block portion 13. 4 that it is projected as a retractable from the surface 15 of the block portion 13. More specifically, the two cylindrical stopper protrusions 14 are preferably a light metal material such as aluminum, and these stopper protrusions 14 are movably inserted into the insertion holes 16 of the block 13 and A small-diameter screw hole 17 communicating with the insertion hole 16 and a slightly large-diameter adjustment bolt insertion hole 18 are integrally connected to the adjustment bolt 19 for insertion. The stopper protrusion 14 can be moved forward and backward from the block surface 15 through the insertion hole 16 integrally with the adjustment bolt 19 by screwing, and the brake can be applied by the forward rotation (or reverse rotation) of the adjustment bolt 19. The gap between the master cylinder B and each stopper protrusion 14 can be finely adjusted. This adjusted state is maintained by fastening the adjusting bolt screw portion by screwing each set screw 21 into each vertical hole 20 orthogonal to each screw hole 17. In FIG. 1, the two holes 22 provided in the inclined surface portion of the block portion 13 are attachment bolt holes of an attached attachment stay 23.

In this embodiment, the case where two stopper protrusions 14 are provided is shown, but the number is not limited to this, and the number of stopper protrusions 14 is arbitrary. Further, in this embodiment, the gap of the stopper protrusion 14 with respect to the brake master cylinder B is shown by rotating the adjusting bolt 19, but the gap adjustment with respect to the brake master cylinder B is as shown in FIG. Then, the stopper protrusion 14 is fixed (or formed integrally with the block portion 13 of the stopper body 10), and the mounting bottle hole 12 in the mounting portion 11 is used as a horizontally long hole to attach the stopper device to a mounted body (strat house). When it is attached to A, it may be configured to be attached by moving the whole body in either the left or right direction (lateral direction) to adjust the gap.

As shown in FIGS. 4 and 5, the stopper device of the present invention having the above-described structure has the attachment stay 23 attached to the stopper body 10 by screwing the bolt 24 into the attachment bolt hole 22 as required. After being fixed to the block portion 13, this is screwed to the outer surface of the strut house A in the engine room of the four-wheeled vehicle through the mounting hole 12 and the bolt 25 is screwed into the mounting hole of the strut house A and the mounting slats. The bolts 26 are firmly attached by screwing the bolts 26 into the mounting holes of the strut house A through the bolt holes 27 of the stay 23, and then the stopper protrusions 14 are moved by rotating the adjusting bolts 19 to brake. It is adjusted to the extent that it contacts the master cylinder B, and the position of the stopper protrusion 14 is adjusted. Is fixedly held by screwing each set screw 21 into each hole 20. In the case of the embodiment shown in FIG. 7, the horizontally elongated hole 12 of the mounting portion 11 of the stopper body 10 moves the screwing position of the bolt 25 to the left and right to move the stopper protrusion 14 and the brake master cylinder B. It is attached so that the gap between and contacts.

In the four-wheeled vehicle equipped with the stopper device of the present invention, even if the brake master cylinder B is moved (protruded) to the front side with the brake pedal depressed, the brake master cylinder B is moved to the fifth position. As shown in FIGS. 6 and 6, the stopper protrusion 14 is pressed by the surface of the stopper protrusion 14 to prevent movement (protrusion).

[Effect of the device]

 As described above, according to the present invention, the movement (protrusion) of the brake master cylinder to the front side when the brake petal is stepped on is reliably prevented, so that the braking time is shortened and the braking force is further increased. It delivers accurate transmission, improves safety, and gives a "clicky" outstanding brake feeling without feeling spongy when the brake pedal is stepped on.
