Connecting structure of engine and frame

Abstract

The invention discloses a connecting structure of an engine and a frame, which comprises a left suspension support assembly and a right suspension support assembly, the left suspension support assembly comprises a left support, a left bracket and a suspension cushion, and the left support and the left bracket are respectively positioned on two sides of the suspension cushion and are fixedly connected with the suspension cushion; the right suspension support assembly comprises a right support, a right bracket and a suspension cushion, and the right support and the right bracket are located on the two sides of the suspension cushion respectively and fixedly connected with the suspension cushion. The left support is used for being fixedly connected with one side of an engine, and the right support is used for being fixedly connected with the other opposite side of the engine. The left bracket is used for being fixedly connected with a frame on one side of a vehicle, and the right bracket is used for being fixedly connected with a frame on the other side of the vehicle. The connecting structure is simple in structure, convenient to install, high in rigidity and obvious in buffering effect; the engine is arranged in an offset mode, and more space can be reserved on the left side of the engine to install other parts.

Description

technical field [0001] The invention relates to the technical field of vehicle brackets, in particular to a connection structure between an engine and a vehicle frame. Background technique [0002] In order to ensure its rigidity and strength performance, the automobile engine bracket is mostly based on a solid structure. One side of the engine bracket is installed on the engine through bolts, and the other side is connected to the vehicle body through a rubber mount; however, the existing design structure of the mount bracket is relatively It is thick, the shape is not beautiful enough, and the suspension bracket forms a through cavity in the front and rear direction, which leads to the limited assembly space of the suspension connection side bolts and difficult assembly. At the same time, the structure is too low in the vertical direction of the suspension bracket. Insufficient vertical rigidity of the bracket may easily lead to fracture and failure of the suspension brack...

Problems solved by technology

[0002] In order to ensure its rigidity and strength performance, the automobile engine bracket is mostly based on a solid structure. One side of the engine bracket is installed on the engine through bolts, and the other side is connected to the vehicle body through a rubber mount; however, the existing design structure of the mount bracket is relatively It is thick, the shape is not beautiful enough, and the suspension bracket forms a through cavity in the front and rear direction, which leads to the limited assembly space of the suspension connection side bolts and difficult assembly. At the same time, the structure is too low in the vertical direction of the suspension bracket. Insufficient vertical rigidity of the bracket may easily lead to fracture and failure of the suspension bracket; at present, the engine is generally arranged symmetrically, but in the case of a symmetrical layout, the installation space for components such as the transmission shaft and the primary fuel filter is small; therefore, how to improve the suspension bracket It is a technical problem that those skilled in the art need to solve at present to improve the performance of the rigidity and strength of the suspension bracket to buffer the impact of the load, and to reasonably design the installation space of the engine.

[0003] The utility model patent with the notification number CN212765673 discloses an engine suspension bracket that can be quickly disassembled and installed. The bracket has complex structure, many parts involved, and the setting of spring layers will cause the engine to vibrate greatly during the driving process of the vehicle. Problem: The utility model patent with the notification number CN212098405 discloses a heavy truck lightweight engine suspension bracket. The bracket has a large structure and takes up a lot of space, and the structure is fixed only by two bolts. Risk of looseness; the utility model patent with the notification number CN 206367374 discloses an engine suspension bracket and a car. This technical solution does not have a buffer device, and the hard connection of the engine is easy to cause damage, and the bracket is relatively thin, so there is a risk of bracket breakage
