Abstract

The utility model discloses a front suspension flexible cushion for an automobile engine, comprising an upper clamp plate and a lower clamp plate. A vibration absorbing rubber block is arranged between the upper clamp plate and the lower clamp plate; the two side edges at the two ends of the upper clamp plate bend inwards and butt against the vibration absorbing rubber block; the two side edges at the two ends of the lower clamp plate bend inwards and butt against the vibration absorbing rubber block; the upper clamp plate is provided with a bolt and a location pin; the lower clamp plate is provided with two bolt holes; and the part of the vibration absorbing rubber block near the lower clamp board is provided with a through hole. The utility model can avoid the separation hidden trouble of the vibration absorbing rubber block and the upper clamp plate and the lower clamp plate; the location is convenient; and the vibration of the engine can be reduced effectively.

Description

Suspending cushion before a kind of automotive engine

Technical field

The utility model relates to a kind of auto parts and components, specially refers to the preceding suspending cushion of a kind of automotive engine.

Background technology

Soft cushion structure suspends before the existing automotive engine, because its vibration isolation rubber piece is to adhere between the upper and lower clamping plate, again owing to suspend soft cushion structure when normal operating condition before this automotive engine, upper and lower clamping plate are tilting state, the weight of driving engine occurs shearing and compression alternating state, the potential faults that rubber block and upper and lower clamping plate may occur breaking away to the effect of suspending cushion structure.Because the soft cushion structure that suspends before the automotive engine often is installed to earlier on the engine-mounting bracket, be not easy the location by a bolt merely simultaneously.In addition, because this soft cushion structure is applied to from engine assembly center of gravity front of the engine far away, bigger soft cushion structure rigidity is unfavorable for reducing engine vibration.

Summary of the invention

In order to overcome the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of potential faults of avoiding vibration isolation rubber piece and upper and lower clamping plate to occur breaking away from, the preceding suspending cushion of location automotive engine convenient, that effectively reduce engine vibration.

For achieving the above object, the utility model provides a kind of automotive engine preceding suspending cushion, comprise train wheel bridge and lower plate, be provided with the vibration isolation rubber piece between described upper and lower clamping plate, the two ends side of described train wheel bridge bends inwards and is resisted against on the vibration isolation rubber piece.The two ends side of described lower plate bends inwards and is resisted against on the vibration isolation rubber piece, owing to suspend soft cushion structure when normal operating condition before this automotive engine, upper and lower clamping plate are inclined, and said structure can be deviate to prevent the vibration isolation rubber piece.

Described train wheel bridge is provided with a bolt and a locating dowel pin, is used for and the stationary engine mounting bracket.

Have two bolts hole on the described lower plate, be used for fixing with vehicle frame.

Described vibration isolation rubber piece has a through hole near the position of lower plate, and its effect is suitably to reduce the compression of rubber block and shear rigidity, effectively improves quiet deformation performance and patience, makes driving engine reach the better damping effect.

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic;

Fig. 3 is that the B-B of Fig. 2 is to cross-sectional schematic.

Reference numeral wherein:

The 1-lower plate; 2-vibration isolation rubber piece; The 3-bolt; The 4-train wheel bridge; The 5-locating dowel pin; The 6-bolt hole; The 7-through hole.

The specific embodiment

Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2 and shown in Figure 3, suspending cushion is by train wheel bridge 4, lower plate 1 and inserts and puts vibration isolation rubber piece 2 and constitute before the utility model automotive engine, vibration isolation rubber piece 2 wherein adheres between the upper and

lower clamping plate

4,1, train wheel bridge 4 is provided with a bolt 3 and locating dowel pin 5 that soft cushion structure is fixed in engine-mounting bracket, the two ends side of train wheel bridge 4 bends inwards and is resisted against on the vibration isolation rubber piece 2, deviates to prevent vibration isolation rubber piece 2.Have on the lower plate 1 and two fixing bolts hole 6 of vehicle frame, again owing to suspend soft cushion structure when normal operating condition before this automotive engine, upper and

lower clamping plate

4,1 are inclined, lower plate 1 two ends side all inwardly bias be resisted against on the vibration isolation rubber piece 2, deviate to prevent vibration isolation rubber piece 2.Vibration isolation rubber piece 2 has a through hole 7 near the position of lower plate 1, and its effect is suitably to reduce the compression of rubber block 2 and shear rigidity, effectively improves quiet deformation performance and patience, makes driving engine reach the better damping effect.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.

Claims
