Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improvements in a brake master cylinder and clutch master cylinder equipped with a brake servo for a cab-over type automobile, and a pedal bracket for supporting pedals and the like connected to these cylinders.

In general, cab-over type cars are completely different from bonnet type cars, as there is very little space between the driver's seat and the front of the body, so when installing master cylinders in this space, the occupant's feet (knees) must not hit these cylinders. At the same time, it is desirable to prevent the piping of the cylinder from being damaged and to streamline the mounting structure as much as possible so that the pedal arm does not become strained.

This idea provides a structure that rationally solves the above points, and allows the master cylinders to be accurately prevented from twisting the pedal arm, is compact and easy to install, and is designed to prevent the occupant's feet from becoming too tight. This protects the knees, protects the piping, improves aesthetics, and allows smooth pedal operation.

The configuration of this invention will be explained below with reference to the drawings.

In FIGS. 1 and 2, 1 is a brake servo, 2 is a brake master cylinder directly connected to the brake servo, 3 is a bushing rod thereof, 6 is a clutch master cylinder, and 9 is a front plate 9a extending in the vehicle width direction in a substantially vertical position. and the front plate 9a
Lateral side plates 9b, 9 extending toward the rear of the vehicle body from both ends in the vehicle width direction.
b shows a mounting plate integrally molded into a substantially U-shape.

Reference numerals 7 and 7 designate a pair of left and right substantially triangular support plates whose rear upper portions are welded to the front plate 9a portion of the mounting plate 9, and the support plates 7 and 7 and the mounting plate 9 constitute a pedal bracket. ing.

A flange is formed on the upper edge of the mounting plate 9, and the flanges 9c on both side plates 9b, 9b of the mounting plate 9
,9c to the instrument panel 10 by bolting
The pedal bracket is fixed to the lower surface, and the lower ends of the support plates 7, 7 are fixed to the floor panel 8 via a bracket 12, whereby the entire pedal bracket is attached to the vehicle body.

On the front plate 9a of the mounting plate 9, the front surface of the brake servo 1 and the front surface of the clutch master cylinder 6 are horizontally mounted side by side in the vehicle width direction from the rear of the vehicle body.

However, the mounting surface of the clutch master cylinder 6 is a stepped surface 9a' that is slightly shifted toward the rear of the vehicle body from the mounting surface of the brake servo 1.

The bushing rod 3 passes through the front plate 9a and projects toward the front of the vehicle body, and the upper end of the brake pedal 4 is connected to the projecting end.

This brake pedal 4 has a pair of left and right support plates 7 in the middle.
, 7, and is rotatably mounted and supported on a drive shaft 5 installed between them.

The piston rod 13 of the clutch master cylinder 6 passes through the stepped surface 9a' and projects toward the front of the vehicle body, and the upper end of a clutch pedal 14 is connected to this projecting end.

The clutch pedal 14 is rotatably supported at its midpoint by a pivot 16 installed between one support plate 7 and an auxiliary support plate 15 welded to one side plate 9b.

Note that 11 indicates the front panel of the body.

As explained above, this invention is a pedal bracket for a cab-over type automobile that supports a brake mask cylinder and a clutch mask cylinder equipped with a brake servo, and pedals connected to these cylinders. The pedal support plate is composed of a mounting plate to which the pedal is attached, and a pair of left and right pedal support plates that are integrally connected to the mounting plate and rotatably support the pedal, and the upper end of the mounting plate is fixed to the bottom surface of the instrument panel. At the same time, the lower end of the pedal support plate is fixed to the two lower panel, and the mounting plate is held in a substantially vertical position by a front plate extending in the vehicle width direction and a side plate extending from both ends of the front plate in the vehicle width direction toward the rear of the vehicle body. While integrally molded in a substantially U-shape, the brake mask cylinder and clutch mask cylinder equipped with a brake servo are mounted horizontally from the rear side of the vehicle body side by side in the vehicle width direction, and the entire lateral length of both cylinders is covered. Since the above-mentioned side plates are extended to the rear of the vehicle body, there are the following advantages compared to the conventional structure.

In other words, if the front plate and side plate of the mounting plate for attaching the master cylinder are formed by welding or bolting as separate members, the front plate may fall forward or backward or tilt in the left-right direction with respect to the side side plate. Assembling accuracy errors occur, and as a result, the master cylinder cannot be installed in a normal position with respect to the pedal arm, and the pedal arm and pivot axis become distorted. However, since the present invention is constructed as described above, the brake servo There is no possibility of twisting input to the pedal arm and its pivot axis, which is caused by the mounting precision of the mounting plates of the directly connected brake master cylinder and clutch master cylinder.

In addition, the master cylinders can be mounted compactly on a single approximately U-shaped mounting plate, and can be covered. In particular, by making the mounting plate into a single approximately U-shaped mounting plate, the master cylinders can be mounted on a single approximately U-shaped mounting plate. Support rigidity of cylinders can be sufficiently increased.

In addition, since the cylinders are covered by the above-mentioned side plates, the feet (knees) of the occupants do not touch the cylinders when getting on or off the vehicle, which protects the piping of the master cylinders and improves aesthetics. Furthermore, by connecting the pair of left and right pedal support plates to the front surface of the mounting plate for the master cylinders, the width of the approximately U-shaped mounting plate is large, while the distance between the pair of left and right pedal support plates can be reduced. It can be made relatively small, and there is no bending of the pedal arm axis.
This can prevent twisting due to this, and the pair of left and right pedal support plates reinforces the middle part of the front plate of the approximately U-shaped mounting plate. At the top, the front plate of the U-shaped mounting plate and the brake servo are reinforced in the width direction, so the overall connection relationship is rational and has a highly rigid structure, making pedal operation smooth. Can be done.
