Rear support device for light truck engine

Abstract

The invention provides a light truck engine rear bearing device. A bearing frame is composed of a bearing cross beam and two vertical bearing plates symmetrically welded to the left end and the right end of the lower portion of the bearing cross beam. A lower bearing rack is composed of a lower bearing plate and three triangular reinforcing plates welded to the lower bearing plate. The lower bearing rack is welded to the front end face of the middle of an engine rear bearing frame cross beam. The engine rear bearing frame cross beam is riveted to a left frame longeron and a right frame longeron. Support frames are installed on the two sides of a transmission shell of an engine and transmission integrated part in a connected mode. Two buffer rubber mats are arranged on the upper plane of the lower bearing rack, an engine, transmission and support frame integrated part is hoisted, upper cross beams of the support frames are arranged on the two buffer rubber mats, and the support frames and the lower bearing rack are connected through bolts and nuts. By means of the rear supporting device, the use reliability of a truck is greatly improved, and the service life of engine bearing relevant parts is greatly prolonged. The light truck engine rear bearing device is simple in structure and can be widely applied to the light truck.

Description

technical field [0001] The invention relates to the technical field of truck manufacture, in particular to a light truck engine rear supporting device. Background technique [0002] The car engine support device not only bears the weight of the engine and transmission, but also bears the reaction force of the torque output from the engine to the car transmission system. The rear support device of the car engine bears part of the weight and reaction force of the engine and transmission. At present, the engine rear support device of a light truck generally adopts a bracket installed on the engine flywheel housing or the transmission housing, and is supported on the left and right longitudinal beams of the vehicle frame by a cantilever support mode. As light truck engines become more and more diesel-powered and strengthened, especially the use of exhaust gas turbocharging devices is becoming more and more common, the weight and torque of the engine are increasing. As a result,...

AI Technical Summary

Problems solved by technology

As a result, the left and right longitudinal beams of the frame at the installation position of the currently used engine rear support device are deformed, the position of the engine rear support device falls, and the relevant parameters of the automobile transmission system change, resulting in increased noise and wear of the relevant components of the transmission system

Sometimes there is even a phenomenon that the rear support device of the engine breaks
