Abstract

The utility model discloses a vibration damper of engines, which comprises a mandrel, wherein the bottom end of the mandrel penetrates through a vehicle body bracket and is connected with the vehicle body bracket in a swing way; the top end of the mandrel penetrates through an engine bracket; the peripheral face of the mandrel is nested with a first and a second compression springs; the first compression spring is clamped and pressed between the engine bracket and the vehicle body bracket; the second compression spring is clamped and pressed between the top end of the mandrel and the engine bracket. The utility model has the advantages of simple structure, high loading capability, long service life and good vibration damping effect, reduces the vibration on a vehicle frame produced by the engine in all directions and is widely used in vibration damping of various engines for motor vehicles.

Description

A kind of engine snubber

Technical field

The utility model relates to the damper technique field, relates in particular to a kind of engine snubber of vibrating between motor and the vehicle frame of being used to reduce.

Background technique

Motor on the Motor Vehicle can make vehicle frame produce vibration when work, and then produces noise, driver and passenger is felt under the weather, but also surrounding environment is caused noise pollution, and it is particularly outstanding that this situation shows on three-wheeled motor vehicle.Many producers are provided with rubber shock absorber between motor and car body, this vibration damper is fit to bear pressure and shearing force, but are not suitable for bearing tensile force.The vibration that produces during engine revolution is omnibearing, when rubber shock absorber is subjected to tensile force, can cause the fatigue ruption of vibration damper.In addition, the rubber shock absorber bearing capacity is low, and rigidity is big, and creep effect is arranged, and temperature variation is easy to generate influence to its performance, thereby effectiveness in vibration suppression is undesirable.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of engine snubber simple in structure is provided, its not only can be comprehensive the vibration that produces of absorption motor, and bearing capacity is big, long service life.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of engine snubber, this engine snubber is arranged between engine support and the vehicle body hanger, this engine snubber comprises a mandrel, the bottom of described mandrel passes vehicle body hanger and can swing with it and is connected, and the top of described mandrel passes engine support; The outer circumferential face of described mandrel is nested with first, second pressure spring, and the first pressure spring cramping is between engine support and vehicle body hanger, and the second pressure spring cramping is between mandrel top and engine support.

After having adopted technique scheme, when motor was started working, its vibration passed to shock-absorbing spring by engine support, and downward vibration force is absorbed by first pressure spring, and the vibration force that makes progress is absorbed by second pressure spring; The utility model has not only been brought into play the big advantage of pressure spring bearing capacity, and because the bottom of mandrel passes vehicle body hanger and can swing with it and to be connected, vibration damper can be regulated its orientation automatically, make pressure spring axially absorb the vibration force that motor produces along it, realized the comprehensive absorption of vibration, long service life, good damping result.

As a kind of improvement, the axial two ends of described first pressure spring are respectively equipped with can limit spring buffer pad that first pressure spring moves radially, flexible.This spring buffer pad not only can limit first pressure spring and move radially, the noise that produces when reducing spring vibration, and, can further strengthen effectiveness in vibration suppression because it is flexible.

As further improvement, the axial top of second pressure spring is provided with spring guide, and the outer circumferential face on described mandrel top is provided with screw thread, and which is provided with can be with the nut of the second pressure spring cramping between engine support and spring guide.Its effect is, not only is convenient to the installation and removal of whole vibration damper, and can passes through swivel nut, regulates the tight power of giving of second pressure spring easily, to adapt to the needs of different excitation forces.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model first embodiment's a structure sectional view;

Fig. 2 is the utility model second embodiment's a structure sectional view.

Embodiment

First embodiment: as shown in Figure 1, a kind of engine snubber has a mandrel 1, and the bottom of mandrel 1 passes vehicle body hanger 2 and contacts with its spherical angle, and the top of mandrel 1 passes engine support 7; The outer circumferential face of mandrel 1 is nested with first, second pressure spring 6,8, the axial two ends of first pressure spring 6 are respectively equipped with can limit the spring buffer pad 5 that first pressure spring 6 moves radially, this spring buffer pad 5 should be flexible, preferentially selects the rubber material manufacturing for use.Engine support 7 and vehicle body hanger 2 are fixedly connected with the guard ring 3 of restraining spring cushion pad 5 radial deformations respectively, like this, first pressure spring 6 just by cramping between engine support 7 and vehicle body hanger 2.The axial top of second pressure spring 8 is provided with spring guide 9, the outer circumferential face on described mandrel 1 top is provided with screw thread, which is provided with nut 10, such second pressure spring 8 just by cramping between spring guide 9 and engine support 7, and can regulate second pressure spring 8 by nut 10 and give tight power.

For the spring that improves spring buffer pad 5 supports the wear resistance and the compressive strength of end face, between itself and first pressure spring 6, be provided with rigidity packing ring 4.

When motor was started working, its vibration force passed to shock-absorbing spring by engine support 7, and downward vibration force is absorbed by first pressure spring 6, and the vibration force that makes progress is absorbed by second pressure spring 8; The utility model has not only been brought into play the big advantage of pressure spring bearing capacity, and because the bottom of mandrel 1 passes vehicle body hanger 7 and can swing with it and to be connected, vibration damper can be regulated its orientation automatically, make pressure spring axially absorb the vibration force that motor produces along it, realize the comprehensive absorption of vibration, long service life, good damping result.

As shown in Figure 2, second embodiment's the structure and first embodiment are basic identical, its difference is: the joint of the bottom of mandrel 1 and vehicle body hanger 2 is provided with angular contact articulated bearing or thrust articulated bearing 11, can reduce mandrel 1 difficulty of processing like this, is convenient to standardized production.The utility model is not limited to above-mentioned embodiment, as long as the bottom of mandrel 1 can be swung with vehicle body hanger 2 is connected, and will fall within the protection domain of the present utility model.
