Description

[Detailed Description of the Invention] This invention relates to a brake master cylinder mounting device for an automobile, particularly a cab-over type automobile.

Normally, in a cab-over type car, the brake master cylinder is placed in the interior space in front of the driver's seat. Only a small space is available.
Furthermore, in recent years, brake master cylinders with boosters (boosting devices) have been increasingly used to improve brake performance.

For this reason, the rear end of the brake master cylinder is
It is located close to the driver's knees, and in the event of a severe collision, the deformation of the front of the vehicle body will push the brake master cylinder backwards, causing the rear end of the brake master cylinder to damage the driver's knees and shins. There was a risk of injury.

In view of the above-mentioned conventional problems, this idea has been improved and eliminated.The pedal support part is connected to the lower part of the front of the vehicle body, and the brake master cylinder support part is connected to the upper part of the rear part of the vehicle body from the point where the pedal support part is connected to the vehicle body. A support bracket is provided in front of the driver's seat which is rotatably connected to a rigid member located at the front of the driver's seat, and a brake master cylinder is fixed to the support bracket. By deforming and rotating the support bracket downward around the pivot point between the brake master cylinder support part and the rigid member, the rear end of the brake master cylinder is avoided upward without being pushed rearward, thereby preventing the driver's knees from being pushed out. This is designed to prevent injuries to the legs and shins.

The configuration of this invention will be described below with reference to embodiments shown in the drawings.

In Figures 1 and 2, 1 is a front panel, 2 is a floor panel, 3 is an instrument panel installed along the vehicle width direction in front of the driver's seat,
4 is a rigid member such as a reinforcing member of the instrument panel 3, which is preferably disposed outside the clutch area C at the front of the vehicle body, and has a supporting rigidity that does not deform even when a considerably large load is applied. . Reference numeral 5 designates a support bracket disposed at the front of the vehicle body, which includes a pedal support portion 6 to which a pedal is attached, and a brake master cylinder 1 with a booster.
0 is attached to the brake master cylinder support part 7. The pedal support section 6
is formed by a pair of plate-like pieces 6R, 6L, with bent pieces 8R, 8L, 8R', 8L' formed at the front and rear ends of each plate-like piece, and the brake pedal 9 is pivoted between both plate-like pieces 6R, 6L. Wear it freely. And pedal support part 6
Connect the front bent pieces 8R, 8L to the lower bracket 11 of the front panel 1 with bolts 12,
The rear bent pieces 8R' and 8L' are integrally connected to the brake master cylinder support part 7. The brake master cylinder support portion 7 is U-shaped and has a front plate 13 and side plates 14, 14'. Then, the bolt 16 provided on the front side of the booster 15 is inserted into the front plate 13 by passing through the front plate 13 and the rear bent pieces 8R' and 8L' of the pedal support section 6, and the nut 17 is fastened thereto to secure the pedal. Support part 6 and brake master cylinder support part 7
The booster 15 is integrated with the front plate 13 of the brake master cylinder support section 7.
The brake master cylinder 10 integrated with the brake master cylinder 10 is fixed. Further, a support arm 1 extends integrally from the rigid member 4 at the rear end portion of both side plates 14, 14' at an upper position behind the position where the pedal support section 6 is connected to the vehicle body.
8 and 18', and are rotatably connected by a pivot pin 19, so that the brake master cylinder support part 7 is supported by the rigid member 4. For the pivot pin 19, for example, as shown in FIG. 3, a stepped pin is used, and the stepped portion 19a is inserted into the side plates 14, 14' and the support arms 18, 18' of the brake master cylinder support section 7. Tighten the nut 21 via the spring washer 20. When tightening the nut 21, there will be no rotation or rattling during normal brake operation.
It is designed to rotate when a load exceeding a predetermined value is applied.

In the above configuration, the operation thereof will be explained. During normal driving, the brake pedal 19 and the brake master cylinder with booster 10 are supported by the support bracket 5 which has sufficient support rigidity against the pedal depression force, and It does not interfere with operation.

However, in the event of an automobile collision, the front end of the pedal support portion 6 of the support bracket 5 is pushed rearward as the front portion of the vehicle body deforms due to the deformation of the front portion of the vehicle body, and a collision load acts on the support bracket 5. Then, the tip of the pedal support part 6 is connected to the lower part of the front panel 1, and the rear end of the brake master cylinder support part 7 is connected to the rear part where deformation is slower than the front part of the vehicle body, preferably outside the clutch area C, and The support bracket 5 is rotatably supported by a rigid member 4 above the vehicle body connection part 6, and as a result, the support bracket 5 is rotatably deformed downward around the rear end pivoting part of the brake master cylinder support part 7. . Therefore, the brake master cylinder 10 with booster rotates counterclockwise,
Since the rear end is avoided above the driver's knees, it will not be pushed backwards and cause injury to the driver's knees and shins.

In addition, although the invention of the present application describes the installation of the brake master cylinder 10 that integrally has the booster 15, the interior space in front of the driver's seat is significantly narrower,
Furthermore, the present invention can be similarly applied to the installation of a single brake master cylinder in a cab-over type vehicle, which is a light vehicle that does not normally have a booster, to improve safety.

As explained above, this invention provides a support bracket consisting of a pedal support section and a brake master cylinder support section, and is used in a cab-over type automobile in which a brake master cylinder is disposed in front of the driver's seat using the support bracket. The pedal support part is connected to the lower part of the front of the vehicle body, and the brake master cylinder support part is rotatably pivoted to a rigid member located at the upper part behind the position where the pedal support part is connected to the vehicle body. However, the rear end of the brake master cylinder is not pushed backwards and is avoided above the driver's knees, which prevents collisions in cab-over vehicles where the brake master cylinder is located in a narrow space in front of the driver's seat. It can dramatically improve the safety of the time.
