The utility model discloses can not only the accurate engine displacement of restriction, long service life and vibration isolation performance are good moreover.
Description
Technical field
The utility model relates to the device that connects motor and vehicle body, relates in particular to the preceding suspending soft cushion assembly of a kind of motor car engine.
Background technique
Automobile power assembly is main vibration and the noise source on the automobile, in order to make car load the good comfort ability is arranged, and uses suspending soft cushion assembly that motor is connected with vehicle frame usually.The topmost effect of suspending soft cushion assembly is the supporting engine power assembly before the motor car engine; Bear the dynamic and static load under its various operating modes; And the displacement of power assembly on all directions is in the acceptable scope, not with front deck in other component and vehicle body interfere.Thereby the design of engine mounting system is extremely important, requires it can realize absorbing, vibration damping and vibration isolation, reduces noise, with the requirement of the comfort property that satisfies car load.
As shown in Figure 1, existing engine front mounting cushion assembly comprises upper skeleton 10, lower skeleton 11 and rubber body 12.Rubber body 12 adheres between upper skeleton 10 and the lower skeleton 11, and the two ends of upper skeleton 10 bending downwards are resisted against on the rubber body 12, and the free end after lower skeleton 11 bendings is higher than the free end after upper skeleton 10 bendings.Upper skeleton 10 is connected with motor (not shown) through first bolt 13, and lower skeleton 11 is fixing through second bolt 14 and vehicle frame (not shown).
Yet; On the one hand; Because the rubber body in the existing engine front mounting cushion is to adhere between upper skeleton and the lower skeleton and this suspending cushion is when normal operating condition and is in tilted layout; The weight of motor occurs shearing and compression alternating state, the hidden danger that rubber body and upper skeleton and lower skeleton possibly occur breaking away to the effect of suspending cushion.On the other hand, because the rubber body in the existing engine front mounting cushion is to be exposed among the physical environment, the rubber body ageing failure appears easily.Again on the one hand, because existing engine front mounting cushion spacing on vertical direction is undirected, thereby when crossing bad working environments such as hollow when motor road, suspending cushion can't control effectively to the displacement of motor at vertical direction.
Therefore, be necessary to provide the preceding suspending soft cushion assembly of a kind of motor car engine to overcome above-mentioned defective.
The model utility content
The purpose of the utility model provides a kind of accurately limiting engine displacement, and long service life and the good preceding suspending soft cushion assembly of motor car engine of anti-vibration performance.
To achieve these goals; Suspending soft cushion assembly comprised upper skeleton, rubber body and the lower skeleton that is connected with vehicle frame that is connected with motor before the utility model provided a kind of motor car engine; Lower skeleton is the tubular structure that an end opening and the other end are provided with first mounting hole; Rubber body is contained in the lower skeleton and the inner side surface of the other end of the upper-end surface of rubber body and lower skeleton is fixed; Offer second mounting hole corresponding with first mounting hole of lower skeleton on the rubber body, upper skeleton passes first mounting hole of lower skeleton and second mounting hole of rubber body is fitted in the rubber body.
Preferably; In the middle of comprising, lower skeleton is provided with the limited part of first mounting hole, the tubular joint that extends along the base of limited part and outward extending assembly department along the base of joint; The assembly department of lower skeleton is connected with vehicle frame, and rubber body is contained in the joint of lower skeleton and the inner side surface of the limited part of upper-end surface and lower skeleton is fixed.
Preferably, the limited part of lower skeleton is tapered, and the joint of lower skeleton is cylindrical, and the external frame of the assembly department of lower skeleton is rectangular.
Preferably, offer first bolt hole on four of the assembly department of lower skeleton jiaos.
Preferably, the top of rubber body is tapered, and the bottom of rubber body is cylindrical.
Preferably; Suspending soft cushion assembly also comprises punch pad and lower bolster before the utility model motor car engine; Rubber body is located between punch pad and the lower bolster and with punch pad and lower bolster sulfuration and is one; Punch pad is welded on the inner side surface of limited part of lower skeleton; Offer three mounting hole corresponding with second mounting hole of rubber body on the punch pad, upper skeleton passes first mounting hole of the limited part of lower skeleton, the 3rd mounting hole of punch pad and second mounting hole of rubber body successively and is fitted in the rubber body.
Preferably, punch pad is tapered, and lower bolster is ring.
Preferably, the base of upper skeleton is outward extended with flange, and the flange of upper skeleton is stuck in the rubber body.
Preferably, upper skeleton is provided with positioning convex and symmetrical second bolt hole that is located at the positioning convex both sides.
Preferably, the bottom of rubber body offers the round taper hole that vertically extends.
Compared with prior art, because lower skeleton is a tubular semi-surrounding structure, when motor has the displacement of vertically going up; What lower skeleton had limited rubber body receives force compresses to top offset and the rubber body that is arranged in lower skeleton; Carried the pressure that produces in the running process, thereby not only played spacing effect but also played the effect of bumper and absorbing shock, thereby; The cushion assembly of the utility model had both been controlled the displacement of motor, had reached good vibration isolating effect again.In addition, because lower skeleton is a semi-surrounding formula structure, the top of rubber body is through the upper skeleton sealing; The remaining part of rubber body can surround through lower skeleton; Thereby make rubber body and extraneous environment isolate, thereby prevent that effectively pollutant from corroding rubber, the working life of having improved cushion assembly.Moreover rubber body is in the compression stand under load under normal operating condition, thereby has prolonged the working life of rubber body.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
