Description

Novel driving shaft support and engine matching surface mounting structure

Technical Field

The invention relates to the technical field of transmission shaft supports, in particular to a novel mounting structure for a matching surface of a driving shaft support and an engine.

Background

The transmission shaft is used for transmitting the power of an engine to wheels together with a gearbox and a drive axle so as to enable an automobile to generate driving force, and is an important part for transmitting the power in an automobile transmission system. At present, most vehicle type drive shaft support structures do not have a limiting function, so that the drive shaft is not coaxial with a central hole of a differential mechanism in a transmission assembly after being assembled, the durability of the drive shaft and the NVH performance of a whole vehicle are finally affected, and the customer experience is extremely poor.

The structure of the prior art scheme is as follows: the engine passes through threaded connection with the derailleur, and the drive shaft assembly passes through splined connection with the derailleur by the drive shaft support of threaded connection on the engine assembly, needs manual calibration screw thread mounting hole position in the assembling process, and extravagant man-hour leads to serious disalignment phenomenon easily after the assembly, finally influences the durability of drive shaft and influences whole car NVH performance.

Disclosure of Invention

The invention aims to provide a novel mounting structure for the matching surface of a driving shaft support and an engine, which is additionally provided with an engine mounting hole position limiting structure, wherein a limiting hole is formed in one side of a mounting surface, and meanwhile, a limiting block is arranged on the driving shaft support.

In order to achieve the purpose, the invention provides the following technical scheme: the novel driving shaft support and engine matching surface mounting structure comprises an engine and a driving shaft support, wherein a mounting surface is arranged on the engine, a limiting hole and a mounting hole are formed in one side of the mounting surface, a limiting block and a reference hole which are matched with the limiting hole and the mounting hole are formed in the mounting plate of the driving shaft support, and a screw is connected to the inner thread of the mounting hole.

Preferably, the bottom of the driving shaft support is provided with a shaft hole, and a bearing is installed in the shaft hole.

Preferably, an oil storage chamber is arranged inside the drive shaft bracket.

Preferably, an oil filling hole is formed in one side of the oil storage cavity, and a plug is installed inside the oil filling hole.

Preferably, a protective pipe is inserted into the shaft hole, and a communicating hole is formed between the top of the protective pipe and the oil storage cavity.

Preferably, protective covers are mounted at two ends of the protective pipe.

Compared with the prior art, the invention has the beneficial effects that:

according to the invention, the engine mounting hole position limiting structure is added, the limiting hole is arranged on one side of the mounting surface, and meanwhile, the limiting block is arranged on the driving shaft support, so that the influence of different axial degrees caused by the offset of the driving shaft support can be effectively prevented.
