Engine front cover with suspension right bracket installation structure

Abstract

The invention discloses a motor front cover with a hanging right support installation structure. The motor front cover with the hanging right support installation structure comprises a motor front cover body and a right support installation platform which is arranged on the exterior side of the motor front cover body; a hanging bolt installation hole is formed in a supporting boss; a first reinforcing rib and a second reinforcing rib are arranged above a root portion which connects the right support installation platform and the motor front cover body; a third reinforcing rib is arranged under the root portion which connects the right support installation platform and the motor front cover body; an included angle beta which is formed between a right support installation surface of the right support installation platform and the motor front cover body is from 90.3 to 90.5 degrees. The motor front cover with the hanging right support installation structure has the advantages of being good in assembling manufacturability and high in intensity, improving reliability of connection between an integral vehicle and a power assembly and prolonging the service life of the motor and the integral vehicle.

Description

technical field [0001] The invention relates to parts of automobiles, in particular to a front engine cover with a suspension right bracket installation structure. Background technique [0002] The powertrain is one of the four important components of a car, the power source of the vehicle, and the heart of the car. Due to the difference in the overall layout of the engine and the vehicle, there are various suspension designs in the cabin, such as: three-point design, four-point design, etc. With the rapid development of automobile technology, various structural transmission assemblies are mounted on the engine to meet different customer needs, such as: MT (manual transmission), AT (automatic transmission), DCT (dual clutch transmission), etc. The weight of different transmission assemblies varies greatly, which directly leads to an increase in the total weight of the powertrain. Whether the engine can continuously provide strong power in a reliable working environment dep...

Problems solved by technology

[0003] The structure of the engine front cover of the existing band suspension right bracket installation structure is as follows: Image 6 As shown, this structure has the following problems. First, due to the increased weight of the transmission and other auxiliary structures, the force on the engine assembly increases, especially the force on the right bracket connection position

The structure has stress concentration at position A in the figure, and the structural strength does not meet the design requirements; secondly, because the vehicle production line assembles the right bracket, the operator needs to tilt the bolt sleeve at a certain angle to tighten the bolt torque, as shown in the figure F1 direction, this angle is not easy to control, it is easy to cause the bolts or threaded holes to slip, resulting in poor assembly process
