A transmission assembly and a bulk cement semi-trailer

Abstract

The invention discloses a transmission assembly device, which includes an air compressor, a diesel engine and a transmission bracket, wherein the transmission bracket includes a main longitudinal beam, a main cross beam, an intermediate longitudinal beam and a middle supporting plate, and two main longitudinal beams are arranged, respectively It is detachably installed on both sides of the tank seat; there are two main beams, and the two main beams are arranged side by side on the part of the two main longitudinal beams protruding from the tank seat at a certain distance; there is at least one middle longitudinal beam, and two The ends are respectively connected with the two main beams and are located between the two main beams; the middle support plate is set on the lower end surface of the middle beam and is detachably connected with the tank seat. During use, in addition to the main beam bearing other In addition to the bending moment brought by the components, because a middle support plate connected to the tank seat is set on the middle longitudinal beam, it can share part of the bending moment of the main longitudinal beam, so that it can bear a larger bending moment and reduce deformation , to facilitate future disassembly and installation. The invention also discloses a bulk cement semi-trailer.

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
