Abstract
The utility model relates to an anti-collision engine suspending assembly, which comprises a welding support, an inner sleeve pipe, a rubber main body, an installing support and a bolt. Interference press mounting is performed on the rubber main body inside the welding support. The inner sleeve pipe passes through the rubber main body. The installing support is connected with the inner sleeve pipe through the bolt. A semi-circular-ring shaped anti-collision structure which is formed on the two sides of the rubber main body through vulcanization serves as a block between the welding support and the installing support. The anti-collision structure which replaces an original anti-collision washer will cast no influence due to rotation on anti-collision performances. The engine suspending assembly has the advantages of better anti-collision effects and longer service lifetime.
Description
Technical field
The utility model belongs to technical field of automobile engine, is specifically related to a kind of suspension structure of engine.
Background technology
Along with constant development of economy, the people are when living standard improves constantly, and are also more and more higher to the requirement of quality of life, and to as the human indispensable vehicle---the traveling comfort of automobile requires also more and more higher.Engine mounting has served as the bridge that connects driving engine and car load, mainly contains following effect:
● isolate of the vibration of power assembly systems communicate to vehicle body and chassis;
● isolate the vibration of different ground-surface excitations to power assembly;
● support and the stationary engine dynamic assembly;
● the torque loads and the exciting force of control power assembly;
● in braking, turn, under the working conditions such as acceleration, control moving of power assembly.
In the process that moves of control dynamic assembly, avoid suspending that to bump be the problem that needs are paid attention to, also be the main direction of this patent.
As shown in Figure 1, suspension structure of engine generally comprises welding support 1, crashproof washer 2, inner sleeve 3 and body of rubber 4.Crashproof washer 2 is installed in above the inner sleeve 3, body of rubber 4 here mainly plays and supports driving engine, vibration isolation and radially carrying out crashproof spacing effect, and the axially main crashproof washer 2 that relies on is crashproof spacing, this crashproof washer is easy in the process of using around inner sleeve 3 rotations, from Fig. 2 we as can be seen, mounting bracket 5 is connected with inner sleeve 3 by bolt 6, if crashproof washer 2 rotates, welding support 1 can occur direct impact with mounting bracket 5 in motion process so, and abnormal sound takes place.In addition, a part needs two crashproof washers, increases cost; In crashproof process, collide mutually, there is bigger test in the crashproof washer life-span with welding support 1 and mounting bracket 3.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of engine mounting assembly, and with lower cost, the reliable more and crashproof effect of actv. is optimized mounting structure, improves driving engine single-piece NVH performance.
The technical solution of the utility model is as follows:
A kind of engine mounting assembly of anticollision comprises welding support, inner sleeve, body of rubber, mounting bracket and bolt; Described body of rubber interference is fitted in the welding support, and inner sleeve passes body of rubber, and mounting bracket is connected with inner sleeve by bolt;
It is characterized in that: be formed with the collision protection structure that protrudes the semicircular ring shape in the sulfuration of the both sides of described body of rubber, be blocked between welding support and the mounting bracket.
Described inner sleeve also is fixed together with the body of rubber sulfuration.
Generally be suspended at outside the function that relies on body of rubber load-bearing damping, also play spacing crash-proof effect, but axially coming the restrictive axial bump with regard to needing to increase by two crashproof washers (each one on both sides) in radial direction.And the utility model is just done body of rubber suitable optimization, and by vulcanize out the collision protection structure of a semicircular ring shape in the body of rubber both sides, the collision protection structure of this protrusion has replaced the effect of crashproof washer on function.This structure only needs a secondary mould with the rubber bodies sulfidization molding.This structure and body of rubber are one, can not occur rotating and influence the problem of crashworthiness.And this collision protection structure only and mounting bracket bump, and crashproof washer can not appear owing to be movable, between mounting bracket and welding support, collide mutually, influence the problem in life-span.
As seen, the utlity model has crashproof better effects if, the advantage of longer service life.
Description of drawings
Fig. 1 is the structural representation of existing engine mounting.
Fig. 2 is the structural representation of existing engine mounting assembly.
Fig. 3 is the structural representation of the engine mounting that the utility model proposes.
Fig. 4 is the architecture figure of the engine mounting assembly that the utility model proposes.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
See Fig. 3 and Fig. 4, this engine mounting assembly comprises welding support 1, later-model collision protection structure 7, inner sleeve 3, body of rubber 4, mounting bracket 5 and bolt 6.The both sides sulfuration of body of rubber 4 is formed with the collision protection structure 7 that protrudes the semicircular ring shape, and body of rubber 4 is a kind of materials with collision protection structure 7, also vulcanizes with inner sleeve 3 in forming process.Body of rubber 4 is fitted in by interference with welding support 1, mounting bracket 5 is fixing with inner sleeve 3 by bolt 6, bolt hole above the welding support 1 forms with vehicle body and is fastenedly connected, and the through hole above the mounting bracket 5 forms with driving engine and is fastenedly connected.
When driving engine moved, the displacement of mounting bracket 5 was bigger, and collision protection structure 7 is here for the crashproof spacing important effect that just plays.
Claims (2)
1. an engine mounting assembly comprises welding support (1), inner sleeve (3), body of rubber (4), mounting bracket (5) and bolt (6); Described body of rubber (4) interference is fitted in the welding support (1), and inner sleeve (3) passes body of rubber (4), and mounting bracket (5) is connected with inner sleeve (3) by bolt (6);
It is characterized in that: be formed with the collision protection structure that protrudes the semicircular ring shape in the sulfuration of the both sides of described body of rubber (4), be blocked between welding support (1) and the mounting bracket (5).
