Transmission assembly device and bulk cement semitrailer

Abstract

The invention discloses a transmission assembly device. The transmission assembly device comprises an air compressor, a diesel engine and a transmission support. The transmission support comprises two main longitudinal beams, two main transverse beams, one or more middle longitudinal beams and a middle supporting plate. The main longitudinal beams are detachably installed on the two sides of a tank base respectively. The main transverse beams are arranged at the portions, extending out of the tank base, of the two main longitudinal beams at an interval and side by side. The two ends of the middle longitudinal beam are connected with the two main transverse beams respectively, and the middle longitudinal beam is located between the two main longitudinal beams. The middle supporting plate is arranged on the lower end surface of the middle longitudinal beam and detachably connected with the tank base. In the use process, the main longitudinal beams bear bending moment brought by other components, due to the fact that the middle supporting plate connected with the tank base is arranged on the middle longitudinal beam and can share part of the bending moment for the main longitudinal beams, the main longitudinal beams can bear larger bending moment, deformation is reduced, and disassembly and assembly in future are convenient. The invention further discloses a bulk cement semitrailer.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a transmission assembly and a bulk cement semi-trailer. Background technique [0002] The bulk cement semi-trailer needs compressed air to gasify the material when unloading, and to drive the material out of the cylinder. At present, there are generally two ways to provide compressed air for the bulk cement semi-trailer. One is to use an external air source to provide compressed air, and the other is to Compressed air is provided by the bulk cement semi-trailer itself carrying a diesel engine and an air compressor drive. The external air source has the advantages of high efficiency and low cost, but the external air source cannot be carried with the vehicle and cannot meet the needs of different working conditions. Therefore, when there is no external air source available, the diesel engine and The transmission of the air compressor to provide compressed air. [000...

The external air source has the advantages of high efficiency and low cost, but the external air source cannot be carried with the vehicle and cannot meet the needs of different working conditions. Therefore, when there is no external air source available, the diesel engine and The transmission of the air compressor to provide compressed air

[0003] In the prior art, in order to reduce the weight of the vehicle body and improve fuel economy, a detachable transmission device is generally used, and it is removed when it is not needed to reduce the weight of the vehicle body and achieve the purpose of saving fuel. The current detachable transmission device generally consists of two A cantilever beam structure composed of longitudinal beams detachably installed on the tank seat of the bulk cement semi-trailer is used to support the entire transmission device. The longitudinal beams need to bear a large bending moment, and the requirements for the longitudinal beams are high. During the production and use , the longitudinal beam is easily deformed, which makes it difficult to disassemble
