Embodiment Construction

[0030] refer to figure 2 , the four-point engine mount system in this embodiment includes a pair of engine front mounts and a pair of engine rear mounts. Wherein, the front suspension of the engine is the same as the prior art, including a front suspension cushion 1.1, a front suspension bracket 1.3 and an engine bracket 1.2 connected together through the front suspension cushion 1.1. The improvement lies in the rear suspension of the engine, including: a rear suspension cushion 3.1, an engine foot 3.2 and a rear suspension bracket 3.3.

[0031] refer to figure 2 , the rear suspension cushion 3.1 is a rubber part, which has a tubular main part 3.1.1 and a limiting flange 3.1.2 located on the outer circumference of one end of the main part 3.1.1, that is, the main part 3.1.1 The central hole runs through the limit flange 3.1.2. By changing the radius and length of the main part 3.1.1 or changing the formula of the rubber material, the stiffness parameters of the rear suspe...

Abstract

The invention provides a rear suspension of an engine. The rear suspension comprises a rear suspension cushion, an engine supporting foot and a rear suspension bracket. The rear suspension cushion is a rubber piece and provided with a tubular main body part and a limiting flange, wherein the limiting flange is positioned on the outer circumference of one end of the main body part. The engine supporting foot is metal casting and provided with a mounting part, a limiting boss and a cylindrical part, wherein the limiting boss protrudes out of the mounting part; and the cylindrical part extends out of the limiting boss. The rear suspension bracket comprises a mounting frame, a supporting frame and a fixed frame, wherein the supporting frame is fixed on the mounting frame. The cylindrical part of the engine supporting foot is inserted into the main body part of the rear suspension cushion; the supporting frame of the rear suspension bracket is buckled up with the fixed frame so as to clamp the main body part of the rear suspension cushion in a circumferential direction; one side of the limiting flange is abutted against the limiting boss; and the other side of the limiting flange is abutted against the supporting frame and the fixed frame. The invention further provides a four-point engine suspension system. The engine rear suspension and the four-point engine suspension system have the advantages of good stress capability and good universality.

Description

technical field [0001] The invention relates to the field of engine vibration reduction, in particular to an engine rear mount and a four-point engine mount system. Background technique [0002] The engine mount system is mainly used to support the powertrain (engine, clutch and gearbox), isolate the vibration of the engine, and limit the displacement of the powertrain. Its main components are suspension pads, suspension brackets and engine brackets. [0003] At present, light trucks at home and abroad basically adopt four-point mounts, with two points for the front and rear mounts. The front mounts are arranged on both sides of the front end of the engine block, and the rear mounts are arranged on both sides of the rear end of the gearbox housing. The four-point suspension has strong stability. [0004] The four-point engine mount system of prior art such as figure 1 shown. The engine suspension system includes: a front suspension pad 1.1, a front suspension bracket 1.2...
