Description

TECHNICAL FIELD

[0001] The utility model relates to the field of engineering vehicles, in particular to a short wheelbase dump truck chassis and vehicle. BACKGROUND

[0002] The short wheelbase dump truck on the market has a small turning radius, good passability and the like, and can cope with rural road conditions to the greatest extent. At the same time, it is suitable for short wheelbase single tire vehicles, and a blue license plate can be used to drive domestic demand to the greatest extent. It can also meet the needs of certain city driving restrictions.

[0003] The short wheelbase vehicle has good maneuverability, but since a cargo box needs to be installed above the chassis, the necessary components to be installed on the chassis are all installed on the side wall of the chassis, and there are many necessary components, which leads to a relatively compact layout of the chassis, and the reserved space on the side wall of the chassis after installation is small, making it difficult to perform other modifications during use. In addition, a sub-beam needs to be additionally added to the chassis to install a turnover component to overturn the cargo box for unloading, but the additional sub-beam causes the vehicle cargo box to fall on the sub-beam, increasing the installation height of the vehicle cargo box and resulting in poor vehicle body stability, which is not convenient to use. SUMMARY

DETAILED DESCRIPTION

[0037] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0038] The short-wheelbase dump truck chassis provided by the embodiments of the present application can solve the problems of the short-wheelbase chassis in the prior art, i.e., difficulty in other modifications and poor stability of the vehicle body.

[0039] With reference to Figure 1 The short-wheelbase dump truck chassis disclosed by the present application comprises a chassis 1, a mounting support frame 2 and a lifting support mounting seat 3. The chassis 1 is provided with a plurality of integrated mounting stations on the side wall. The mounting support frame 2 is arranged on the inner wall of the chassis 1 to provide a mounting station for the vehicle rear treatment 21 at the bottom of the chassis 1, so that the rear treatment 21 can be mounted to the bottom of the chassis 1, and then a modification space is formed on the side wall of the chassis 1 where the mounting support frame 2 is arranged, which facilitates users to modify other components on the side wall of the chassis 1 according to their own needs in subsequent use. The lifting support mounting seat 3 is also arranged on the inner side of the chassis 1, and the lifting support mounting seat 3 is arranged in the chassis 1 in a spaced manner with the mounting support frame 2. The lifting support mounting seat 3 is provided with a pushing piece, so that the pushing piece can push the vehicle cargo box 4 from the inner side of the chassis 1. The mounting support frame 2 is not required to be additionally arranged on the chassis 1, so that the integration of the chassis 1 is improved. In addition, the lifting support mounting seat 3 is arranged in the middle of the chassis 1 instead of being arranged close to the front of the vehicle, which changes the pushing starting point, so as to reduce the lifting height of the vehicle cargo box 4 while shortening the pushing stroke, and solves the problems of the short-wheelbase chassis in the prior art, i.e., difficulty in other modifications and poor stability of the vehicle body.

[0040] With reference to Figure 2The pushing piece specifically comprises a pushing oil cylinder 31, a fixed end of the pushing oil cylinder 31 is rotationally arranged on the lifting support mounting seat 3, and a telescopic end of the pushing oil cylinder 31 is used for rotationally connecting with the vehicle container 4. During normal driving of the vehicle, or when the vehicle container 4 is not pushed for unloading, the length direction of the pushing oil cylinder 31 tends to be parallel to the length direction of the vehicle chassis 1, the fixed end of the pushing oil cylinder 31 is inclined to extend a small distance towards the ground, so as to avoid interference between the pushing oil cylinder 31 and the mounting support frame 2 on the vehicle chassis 1, and meanwhile, since the pushing oil cylinder 31 extends a short distance, it will not affect other necessary components on the vehicle chassis 1 and will not affect normal driving of the vehicle. When the vehicle container 4 needs to be unloaded, the telescopic end of the pushing oil cylinder 31 is extended, the fixed end of the pushing oil cylinder 31 is rotated from the vehicle chassis 1 towards the ground, and then the vehicle container 4 is pushed and lifted.

[0041] Further, the lifting support mounting seat 3 comprises a mounting frame, a hinged seat and a first rotating shaft, the mounting frame is fixed on the inner wall of the middle part of the vehicle chassis 1 by bolts, the hinged seat is fixed on the mounting frame by welding, the first rotating shaft is rotationally arranged on the hinged seat, the length direction of the first rotating shaft is perpendicular to the length direction of the vehicle chassis 1, and the fixed end of the pushing oil cylinder 31 is fixed on the first rotating shaft by welding, so that the pushing oil cylinder 31 can rotate around the first rotating shaft, which is simple in structure and convenient to use.

[0042] More specifically, the vehicle chassis 1 comprises a vehicle longitudinal beam 11 and a plurality of vehicle transverse beams 12, the vehicle longitudinal beam 11 is provided with two, and a plurality of bolt holes are arranged on the length direction of the vehicle longitudinal beam 11 to form an integrated mounting station, so as to facilitate subsequent installation of other necessary components on the vehicle chassis 1. The two ends of the length direction of the two vehicle longitudinal beams 11 are connected by the vehicle transverse beams 12 to form the outer frame of the vehicle chassis 1, and a plurality of vehicle transverse beams 12 are also arranged between the length directions of the two vehicle longitudinal beams 11 to form the overall vehicle chassis 1 and improve the overall structural strength of the vehicle chassis 1. In an embodiment of the present application, the mounting frame is specifically arranged on the inner wall of one vehicle longitudinal beam 11.

[0043] Since the bolt holes are arranged on the side wall of the vehicle longitudinal beam 11, if the bolt holes are continuously arranged on the vehicle transverse beam 12, the vehicle transverse beam 12 is prone to excessive light weight, which reduces the structural strength. Therefore, in an embodiment of the present application, the mounting support frame 2 comprises an L-shaped support frame, the L-shaped support frame specifically comprises two support rods which are welded to each other, and the two ends of the L-shaped support frame are welded and fixed between the vehicle transverse beam 12 and the vehicle longitudinal beam 11, so that the post-processing 21 can be mounted on the L-shaped support frame.

[0044] In order to further save the mounting space on the side wall of the frame chassis 1, make the installation of necessary parts on the side wall of the frame chassis 1 more compact, and expand the size of the modification space, the frame chassis 1 is further provided with an integrated mounting bracket. The integrated mounting bracket is fixed on the side wall of the frame chassis 1 by bolts or welding, and a plurality of mounting stations are formed in the integrated mounting bracket. When other necessary parts are installed subsequently, a plurality of necessary parts can be installed on the integrated mounting bracket at the same time, so that the installation structure on the side wall of the frame chassis 1 is more compact, and the size of the modification space is further expanded, so that the use of the frame chassis 1 is more flexible.

[0045] Based on the above-mentioned short-wheelbase dump truck chassis, with reference to Figure 1 The application further discloses a short-wheelbase dump truck, which specifically comprises the short-wheelbase dump truck chassis and a vehicle cargo box 4.

[0046] In order to further improve the stability of the vehicle cargo box 4 rotatingly arranged on the frame chassis 1, a turnover support 41 is welded and fixed to one end of the vehicle cargo box 4 close to the tail end. A second rotating shaft is rotatably arranged at one end of the frame chassis 1 close to the tail end, and is fixedly welded to the frame chassis 1. The length direction of the second rotating shaft is perpendicular to the length direction of the frame chassis 1, so that the vehicle cargo box 4 can be turned over to unload goods with the position of the frame chassis 1 at which the second rotating shaft is arranged at the tail end as the axis. The structure is simple and convenient to use.

[0047] More specifically, the frame chassis 1 of the short-wheelbase dump truck can be divided into a left frame and a right frame along the center line of the frame chassis 1. The left frame is sequentially provided with an oil filter 15, an air dryer 16, a urea tank 17, an oil tank 18 and a rear auxiliary tank 19 from the front end to the tail end. As a preferred embodiment of the application, the oil filter 15 and the air dryer 16 are fixed on the side wall of the frame chassis 1 by an integrated mounting bracket. Two mounting stations are formed in the length direction of the integrated mounting bracket, so that the oil filter 15 and the air dryer 16 are integrated and mounted, the installation of necessary parts on the frame chassis 1 is more compact, and the installation space of the frame chassis 1 is further expanded. The air filter 13 and the storage battery 14 are sequentially arranged on the right frame from the front end to the tail end. The mounting support 2 is arranged on the bottom surface of the right frame, and is located at the middle part of the frame chassis 1. The aftertreatment device 21 and the rear tank 22 are arranged on the bottom of the right frame through the mounting support 2, and form a modification space on the side wall of the frame chassis 1 where the aftertreatment device 21 and the rear tank 22 are arranged, so as to meet the modification requirements of users for necessary parts.
