Abstract

The utility model discloses a light-weight carriage, which is composed of a carriage front panel, a carriage rear panel, side panels and a bottom plate. Weld the front panel of the carriage and the rear panel of the carriage; weld the side panels on the two long sides of the bottom plate respectively. The side panels on both sides are provided with concave reinforcing ribs along the length direction of the side panels. Rib set stiffener plate. Its length direction is provided with two triangular reinforcing ribs concave to the inner side of the compartment, and a reinforcing rib plate is added on the upper side of the side plate. The compartment has no crossbeam and no other reinforcement structure, and its quality is greatly reduced. This kind of carriage structure makes the carriage have the advantages of high strength, small mass and greatly improved loading capacity; at the same time, it reduces fuel consumption, tire wear and vehicle loss, and effectively solves the problem caused by the excessive weight of the dump truck carriage. A series of questions.

Description

a lightweight carriage

technical field

The utility model relates to the technical field of auto parts, in particular to a light-weight compartment for a dump truck.

Background technique

At present, most dump truck compartments use internal panels and external support structures. Specifically, the interior is the compartment panel, and the exterior has beams, vertical braces and other auxiliary structures to increase the strength of the compartment. The quality of this kind of carriage is relatively large. Under the condition that the total mass of the chassis is constant, the load capacity will be greatly reduced, which reduces the utilization factor of the load capacity; and the mass of the carriage is large, the corresponding fuel consumption is also large, tire wear is aggravated, vehicle loss is aggravated, and transportation is increased. Cost; How to solve these problems just seems particularly important, and it is to reduce compartment quality at all. So how to reduce the quality of the carriage, increase the load quality, and the problem that the strength of the carriage cannot be reduced is imminent, and the utility model provides such a carriage.

Contents of the invention

Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a lightweight carriage with high strength, low mass, improved capacity utilization factor, reduced fuel consumption, reduced tire wear and vehicle loss.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a lightweight carriage, which is composed of a carriage front panel, a carriage rear panel, side panels and a bottom plate, and the bottom plate is welded to a bottom plate with a sub-frame On the longitudinal beam, the two short sides of the bottom plate are respectively welded to the front panel and the rear panel of the compartment; the side panels are respectively welded to the two long sides of the bottom panel, and the side panels on both sides are provided with concave reinforcing ribs along the length direction of the side panels. , the top of the inner side of the side plate is provided with a reinforcing rib plate to the reinforcing rib.

In the aforementioned light-weight carriage, the cross-section of the concave reinforcing rib is set to be triangular.

In the aforementioned lightweight carriage, two sets of reinforcing ribs are arranged side by side in parallel along the length direction of the side panels on both sides.

In the aforementioned lightweight carriage, the cross-section of the rib panel is "L"-shaped, and the short-side and long-side endpoints of the "L" shape are respectively connected to the top of the side panel and the triangular concave apex of the rib.

The advantages of the lightweight carriage of the utility model are: the lightweight carriage is composed of a front panel, a rear panel, two symmetrical side panels, a bottom plate, a longitudinal beam of the bottom plate and an auxiliary frame; The triangular reinforcing rib on the inner side of the carriage, and a reinforcing rib plate is added to the top of the side plate. The compartment has no crossbeam and no other reinforcement structure, and its quality is greatly reduced. This car structure makes the car have the characteristics of high strength and small mass, greatly improves the load capacity, improves the utilization factor of the load capacity; at the same time reduces fuel consumption, reduces tire wear and vehicle loss, and effectively solves the problem caused by self-unloading. A series of problems caused by the excessive mass of the car compartment is a special structural device that is economical, environmentally friendly, energy-saving and safe.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail;

As shown in Figures 1, 2, and 3, a lightweight carriage is composed of a front panel 1, a rear panel 2, side panels 3 and a bottom panel 4, and the bottom panel 4 is welded to the bottom longitudinal beam with a subframe 5 6, the two short sides of the bottom plate 4 are respectively welded to the front panel 1 and the rear panel 2 of the compartment; the side panels 3 are respectively welded on the two long sides of the bottom panel 4, and the side panels 3 on both sides are connected through the length direction of the side panels 3 in the interior Concave reinforcing rib 7, its cross-section of concave reinforcing rib is set to triangle; For improving the compartment strength, reinforcing rib 7 is all arranged in parallel parallel to two groups along the length direction of both sides side plates on both sides side plates 3. Rib boards 9 are arranged from the top 8 to the ribs 7 inside the side panels 3 . The reinforcing rib plate 9 is provided with an "L"-shaped section, and the short-side and long-side ends of the "L" shape are respectively connected to the top 31 of the side plate 3 and the triangular concave apex 71 of the reinforcing rib 7 .

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples. Those of ordinary skill in the art can make changes, modifications, additions or replacements within the essential scope of the present utility model. All should belong to the protection scope of the present utility model.
