Description

[Detailed description of the invention] This invention relates to a pedal support structure for a cab-over type vehicle, and is particularly concerned with compactly arranging a brake device including a brake booster in a narrow space in front of the driver's seat. It is an object of the present invention to provide a support structure that secures a wide range of pedals, supports the pedals with high support rigidity, and prevents the adverse effects of brake reaction forces on various pedal-related devices.

In recent years, automobiles have come to be equipped with brake systems that have brake boosters with high braking performance for safety reasons, but unlike bonnet-type automobiles, cab-over-type automobiles are equipped with brake equipment that includes a brake booster with high braking performance. The space between the vehicle and the panel is narrow, and installing a large brake device that occupies a large space in such a narrow space will reduce the space in the driver's seat.

In addition, brake boosters are heavy and have a large reaction force when the brakes are activated, which has a large negative impact on related equipment such as the brake pedal.In order to sufficiently support the brake booster, a considerable amount of support rigidity is required, which requires a large supporting member. However, the number of uses is also increased, which inevitably increases the space occupied, resulting in a problem that the space for the driver's seat is narrowed.

Although the above-mentioned problems generally exist in the above-mentioned structural parts, the present invention employs a special configuration to solve these problems.

In summary, a triangular structure is formed by three types of support members arranged in the vertical direction, support members arranged in the horizontal direction, and reinforcing members arranged in the inclined direction, and the brake booster unit with mask cylinder is attached along the inclination of the reinforcing members. At the same time, the pedal shaft is pivotally attached to the joint between the support member and the reinforcing member, and the structure also realizes the connectivity between the front panel and the front panel and the integrity of the steering device. This special structure is particularly important in this invention.

The configuration of this invention will be explained below according to embodiments shown in the drawings.

In FIGS. 1 to 3, 1 is a floor panel, and 2 is a front panel that constitutes a vehicle interior.

Reference numeral 3 denotes a support member whose lower end is fixed to the floor panel 1 via a bracket 4 and whose upper end stands up vertically along the front panel 2, and whose cross section is approximately U-shaped. The edges are bent outwards, creating a highly rigid shape.

Further, the upper part 3a of the support member 3 is bent slightly parallel to the vehicle width direction.

Reference numeral 5 denotes a support member disposed horizontally at the upper end of the support member 3 so as to intersect with the support member 3. The support member 5 is narrow at the front, becomes wider at the rear, and bulges out in the vehicle width direction as a whole, leaving a peripheral edge 6. The two plate bodies 5a and 5b are made to face each other, the rear peripheral edge 6a is overlapped and fixed by welding, the front part is bent in the vehicle width direction to form a bifurcated shape, and the rear end edge 6b is formed into an arc shape. be.

The bifurcated portion of the support member 5 is fitted onto the outer peripheral surface of the upper end of the support member 3 and fixed by welding, the front end is fixed to the front panel 2 via the bracket 7, and the rear end is connected to the steering shaft (not shown). It is fitted onto the outer periphery of the steering post 8 which is rotatably held and fixed by welding, and the rear upper end is fixed to a rigid member (not shown) of the instrument panel.

Reference numeral 9 denotes a reinforcing member that is installed across the support member 3 and the support member 5 with the upper part inclined toward the rear of the vehicle, and has a U-shaped cross section, with the opening side facing outward. The support member 3 and the support member 5 form a triangle to improve rigidity.

10 is a brake booster placed on the side of the support members 3 and 5 along the direction of inclination of the reinforcing member 9; 11 is a mask cylinder that is integrally attached to the brake booster 10; the rear end of the mask cylinder 11 is attached; The part 11a is made to correspond to the bush 12 fixed to the support member 5 in the vehicle width direction, and the bolt 13 is inserted, and the nut 14 is tightened and fixed. Bolts 16 correspond to bushings 15 fixed through the joint in the vehicle width direction.
is inserted, and the nut 17 is tightened and fixed, and the pedal pusher 19 is inserted through and fixed in the vehicle width direction through the connection bracket 18 attached to the front lower part of the brake booster 10 and the connection part between the support member 3 and the support member 5. The pedal shaft 20 is connected and fixed to one end of the pedal shaft 20 by a fixing plate 21 to be supported.

22 is a brake pedal pivotally attached to one end of the pedal shaft 20, and its tip is connected to the brake booster 1.
It is fixed to a rod 10a protruding from 0 with a pivot 23.

Reference numeral 24 denotes a clutch petal pivotally attached to the other end of the pedal shaft 20, and a clutch cable 25 is connected to the tip of the clutch petal.
It is locked.

With the above configuration, the support member 3, the support member 5, and the reinforcing member 9 are each formed into a highly rigid shape, and the support member 3 forms a box structure between the floor panel 1 and the front panel 2. The support member 5 forms a box structure with the instrument panel, and each member 3. 5. 9 forms a triangular structure, the overall support rigidity is high, and the brake booster 10, mask cylinder 11, etc. are firmly supported.
When the brake is applied, the reaction force from the brake booster 10 is
This brake reaction force is dispersed and absorbed into each part of the support member 3, support member 5, and reinforcing member 9, and this brake reaction force may deform each member 3, 5°9, resulting in a decrease in braking performance or damage to the brake pedal 22, etc. There will be no adverse effect on related parts.

In addition, the brake booster 10 and the mask cylinder 11 are supported by a support member 3, a support member 5, and a reinforcing member 9.
Since the front panel 2 is arranged compactly by tilting it along the reinforcing member 9 in the space formed by the front panel 2 and
By shortening the distance from the steering wheel to the steering post 8, a large space for the driver's seat can be secured.

Further, since the steering post is also integrated into this structure, the structure becomes compact, and the support rigidity of the steering device can be made appropriate by the triangular structure as described above.

As explained above, this invention consists of a support member whose lower end is fixed to the floor panel and whose upper end is arranged vertically along the front panel, whose front end is fixed to the front panel and the upper end of the support member, and whose rear end is attached to the steering wheel. A support member to which a post is fixed and arranged almost horizontally in the longitudinal direction of the automobile, an upper end fixed to the rear end of the support member, a lower end fixed to the support member, and an upper part inclined toward the rear of the automobile. A triangular structure is formed by the three supporting members arranged in the vertical direction, the supporting members arranged in the horizontal direction, and the reinforcing members arranged in the inclined direction, and the supporting members and the reinforcing members are connected. A pedal shaft is mounted on the section, a brake pedal and a clutch pedal are swingably mounted on the pedal shaft, and a brake booster unit with a mask cylinder is arranged along the inclination direction of the reinforcing member to attach each member to the pedal shaft. Since the brake pedal and brake booster are fixedly supported, and the brake pedal and brake booster are connected, the triangular member with high support rigidity is connected to the front panel and floor panel of the space in front of the driver's seat of the cab-over type vehicle by a special arrangement and connection configuration of the three members. Since the structure can be formed compactly and the brake booster unit with a mask cylinder is arranged along the inclined member of the triangular structure, the support strength of the unit can be sufficiently satisfied, and the unit can be It is possible to reduce the space occupied by the vehicle in the longitudinal direction and secure a large space for the driver's seat.Furthermore, since a pedal shaft is provided at the joint between the support member and the reinforcing member to support the brake and clutch pedals, the pedal The force acting on the structure can be distributed to the triangular structure, the front panel, and the floor panel for reliable and firm support.Furthermore, since the steering post is also integrated into the triangular structure, the structure is unified. The steering device can be made compact and the support rigidity of the steering device can be made appropriate.
