Description

Cargo vehicle chassis

Technical Field

The utility model relates to an automobile chassis specifically is a cargo vehicle chassis.

Background

The arrangement of the automobile chassis is an important ring in automobile design, and has a decisive influence on the design quality of the automobile, the performance and the service life of the automobile.

With the increasingly specialized cargo transportation requirements, cargo vehicles, particularly medium-weight trucks, tend to be more personalized and customized in vehicle type configuration, new requirements such as container size specification, endurance mileage, universal design and the like are provided, and accordingly, the chassis of the cargo vehicle needs to be correspondingly structurally improved.

Disclosure of Invention

The utility model provides a current cargo vehicle chassis can't satisfy the problem of cargo vehicle individuality, customization motorcycle type configuration demand, provides a cargo vehicle chassis.

The utility model discloses an adopt following technical scheme to realize: a truck chassis, the front overhang of the whole vehicle (the horizontal distance from the center of a front wheel to the foremost end of the whole vehicle) is 1460mm, and is shortened by 55mm compared with the original vehicle type. Under the unchangeable condition of whole car length, the packing box length that corresponds increases 55mm, has not only increased packing box specification, volume like this, and satisfies the specification of standard tray and standard branch vanning in current logistics distribution in the aspect of the size, makes things convenient for whole, mechanized goods handling, improves work efficiency.

Furthermore, the fuel tank is fixed behind the front axle on the left side of the frame, and the installation space of the fuel tank is reserved according to the 600L fuel tank, so that the fuel tanks with different volumes of 300L/400L/500L/600L can be fixed in the reserved installation space, and can be selected and installed by customers according to the operating mileage of the operating condition, so that the refueling time is shortened, and the cruising mileage is increased.

Furthermore, the air inlet channel and the air filter assembly are fixed behind the front axle on the right side of the frame, so that the air filtering air port of the air inlet channel and the air filter assembly is shorter in pipeline connected with the air inlet of the engine supercharger, and the air inlet resistance is smaller; meanwhile, installation spaces of an air inlet channel and an air filter assembly are reserved behind a front axle on the left side of the frame and in a cab; therefore, the positions of the air inlet channel and the air filter assembly can be exchanged left and right according to the position of the air inlet of the engine supercharger, and the universal design of the arrangement positions of the air inlet channel and the air filter assembly is realized.

Similarly, considering the emission upgrade of the power system, the catalytic reduction muffler post-treatment assembly is selectively installed on the left and the right according to the position of the exhaust port of the engine assembly, namely, installation spaces are reserved on the left side and the right side of the frame, so that the exhaust port of the engine assembly is connected with the catalytic reduction muffler post-treatment assembly through a shorter exhaust steel pipe, the exhaust is smoother, and the exhaust back pressure is small.

The utility model discloses following such as the universalization, the environmental protection that economizes on fuel, packing box size specification, continuation of the journey mileage and starting to pay attention to the performance around the user, given a cargo vehicle chassis, this chassis makes the chassis totality arrange compactly under the condition of guaranteeing sufficient installation and operating space, and each axle load distributes more rationally, has fully satisfied the demand of cargo vehicle individuality, customization motorcycle type configuration, is applicable to various cargo vehicles, is particularly useful for the medium-weight truck.

Detailed Description

A truck chassis comprises a front axle 1, a urea supply system 2, a fuel tank 3, a frame 4, a rear axle 5, a spare tire 6, a cab 7, an air inlet and air filter assembly 8, an engine assembly 9, a transmission 10, a storage battery box assembly 11, an air storage cylinder and air dryer assembly 12, a catalytic reduction muffler aftertreatment assembly 13, a transmission shaft 14 and a tail lamp support assembly 15. The front suspension of the whole vehicle is 1460mm, which is shortened by 55mm compared with the original vehicle. The fuel tank 3 is fixed behind the front axle 1 on the left side of the frame 4, and the installation space of the fuel tank 3 is reserved according to a 600L fuel tank. The air inlet and air filter assembly 8 is fixed behind the front axle 1 on the right side of the frame 4, and meanwhile, the installation space of the air inlet and air filter assembly 8 is reserved behind the front axle 1 on the left side of the frame 4 and the cab 7. The catalytic reduction muffler post-treatment assembly 13 is selectively installed on the left and right sides according to the position of the exhaust port of the engine assembly 9, namely, installation spaces are reserved on the left side and the right side of the frame, so that the exhaust port of the engine assembly 9 is connected with the catalytic reduction muffler post-treatment assembly 13 through a shorter exhaust steel pipe, exhaust is smoother, and exhaust back pressure is small.
