Description

Suspension trailing arm installs bush assembly

Technical field

The utility model is related to vehicle body fittingses field, more particularly to a kind of suspension trailing arm part.

Background technology

In suspension bushes structure in prior art, the rigidity of all directions is different, and difficulty of processing is larger.Do not have in the axial direction Limit function, causes the axial rigidity of bushing poor, it is impossible to meets the vehicle influence of roll force to bushing under steering situation, leads The service life of bushing is caused to decline.In the prior art, bushing rubber part is directly connected with vehicle body, causes to be contacted with each other during motion Friction, produces noise, not only reduces comfortableness, can also aggravate the abrasion of bushing rubber part, have impact on service life.

The content of the invention

Technical problem to be solved in the utility model is to provide a kind of suspension trailing arm and installs bush assembly, the bush assembly One is set near one end of end flanges and strengthen boss, and buffer bush is divided into support using boss is strengthened in buffer bush Section and breeze way so that the end face for there was only inner sleeve in the component is contacted with end flanges, and bushing will not touch vehicle body in itself, The axial rigidity of bushing is improve, unsteadiness of wheels is reduced and is delivered at vehicle body, what reduction vehicle was produced under lateral forces makes an uproar Sound, eliminates collision abnormal sound, improves driver comfort.

What the utility model was realized in：A kind of suspension trailing arm installs bush assembly, including end face locking nut, inner sleeve Pipe, outer tube, buffer bush, end flanges and clamping screw, the inner sleeve suit are fixed on clamping screw, inner sleeve Two ends are coordinated by end face locking nut and end flanges to be fixed, and the outer tube is set with by buffer bush and is fixed on inner sleeve Outward, the outer wall of the buffer bush has been sequentially arranged supporting section, has strengthened boss and breeze way, and the breeze way is located at end flanges Side, the outer tube suit is fixed on outside supporting section.

It is the section that smoothly transits between the supporting section and reinforcement boss, the inner face of the outer tube is provided with and is slipped over light Cross the flange that section is engaged.

The inner sleeve and outer tube are all metal sleeve.

The buffer bush is rubber bushing.

It is an entirety to pass through sulfidization molding between described inner sleeve and buffer bush.

Anise cone cardioid groove, the end flanges and anise cone are offered on the breeze way outer face of the buffer bush Cardioid fit depressions.

The outer tube press-fits and is fixed on buffer bush.

The utility model suspension trailing arm installs bush assembly and sets a reinforcement near one end of end flanges in buffer bush Boss, and buffer bush is divided into supporting section and breeze way using boss is strengthened so that there was only the end of inner sleeve in the component Face contacts with end flanges, is buffered by breeze way between the end face and end flanges of outer tube, can improve the axially firm of bushing Degree, reduces unsteadiness of wheels and is delivered at vehicle body, reduces the noise that vehicle is produced under lateral forces, eliminates collision abnormal sound, carries Driver comfort high, and increase the service life of trailing arm bushing.

Specific embodiment

With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model statement Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen Please appended claims limited range.

Embodiment 1

As shown in Figure 1, 2, 3, a kind of suspension trailing arm installs bush assembly, including end face locking nut 1, inner sleeve 2, overcoat Pipe 3, buffer bush 4, end flanges 5 and clamping screw 6, the suit of the inner sleeve 2 are fixed on clamping screw 6, inner sleeve 2 Two ends pass through end face locking nut 1 and end flanges 5 coordinate fixation, and the outer tube 3 is fixed on interior by the suit of buffer bush 4 Outside sleeve pipe 2, the outer wall of the buffer bush 4 has been sequentially arranged supporting section 41, has strengthened boss 42 and breeze way 43, the breeze way 43 are located at the side of end flanges 5, and the suit of the outer tube 3 is fixed on outside supporting section 41.

For the being firmly combined with property demand of whole component, the inner sleeve 2 and outer tube 3 are all metal sleeve, described slow Bushing 4 is rushed for rubber bushing, as shown in figure 4, the outer surface of the inner sleeve 2 is shiny surface, is served as a contrast with buffering by sulfuration process The inner surface of set 4 is integrated into a whole, and the inner surface of inner sleeve 2 uses five through holes of inner circle corner recess, by the shape Through hole be engaged with the clamping screw 6 of six prisms, meet required for coupling mechanism force；

As shown in figure 5, being the section that smoothly transits between the supporting section 41 and reinforcement boss 42 to improve axial rigidity 44, the inner face of the outer tube 3 is provided with the flange being engaged with the section 44 that smoothly transits, and outer tube 3 is fixed on by press-fiting On buffer bush 4.

As shown in fig. 6, in order to while 4 elastic force of buffer bush is met, use can meet the positioning need of end flanges 5 Ask, anise cone cardioid groove, the end flanges 5 and anise cone are offered on the outer face of breeze way 43 of the buffer bush 4 Cardioid fit depressions, the outer tube 3 and vehicle body made by end flanges 5 and breeze way 43 disengaged, it is to avoid outer tube 3 Because of the abnormal sound that collision is produced between end flanges 5, between buffer bush 4 and vehicle body, the comfortableness of vehicle is improved.
