Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the present invention is further detailed.
As in Figure 2-4, a kind of operator's compartment shock absorption suspension device that the embodiment of the present invention provides, comprise support 21, be arranged at the upper rubber pad 22 at support 21 top and be arranged at the lower rubber pad assembly bottom support 21, lower rubber pad assembly comprises sleeve 23, rubber tube 24 and fixed leg 25, be placed in sleeve 23 in rubber tube 24, be placed in rubber tube 24 in fixed leg 25, the two ends of fixed leg 25 are fixedly connected with support 21; Wherein, fixed leg 25 is arranged in rubber tube 24 and more than longitudinal center line locates, and upper and lower rubber tube 24 being positioned at fixed leg 25 is provided with cavity 26.
Upper and lower, top in the present embodiment, the end is as the criterion with orientation during automobile normal running, operator's compartment upper, vehicle frame under.
Concrete, be placed in rubber tube 24 in fixed leg 25, be placed in sleeve 23 in rubber tube 24, rubber tube 24 like this just act as the cushion rubber of sleeve 23 and fixed leg 25, when wherein vibration occurs one, rubber tube 24 can its Oscillation Amplitude of synchronous fading when transmitting this vibration.Sleeve 23 can be various profile, and as oblong, trapezoidal etc., preferably, sleeve 23 is cylinder, and cylinder is stressed more even, and rubber tube 24 matches with sleeve 23, if rubber tube 24 is cylinder.Fixed leg 25 is eccentric setting in rubber tube 24, and it is positioned at the top of rubber tube 24, so when it is because of vibration-extrusion rubber tube 24, has larger downward amplitude of deformation.And upper and lower rubber tube 24 being positioned at fixed leg 25 is provided with cavity 26, is so more convenient to the distortion of rubber tube 24.The two ends of fixed leg 25 are fixedly connected with support 21, sleeve 23 is fixedly connected with car body, when vibration passes to rubber tube 24 by sleeve 23, rubber tube 24 deforms, due to the cavity 26 on the eccentric setting of fixed leg 25 and rubber tube 24, make that the amplitude of deformation of rubber tube 24 is large and resistance to deformation is little, so, it can damped vibration by a relatively large margin.
The operator's compartment shock absorption suspension device that the present embodiment provides, fixed leg 25 is arranged in rubber tube 24 and more than longitudinal center line locates, and its upper and lower is provided with cavity 26, so, fixed leg 25 just has sizable deformation space for damping, irremovable metal tube compared to existing technology, the damping effect of the present embodiment significantly improves.
In the present embodiment, preferably, the cavity 26 be positioned at above fixed leg 25 is permeate chamber.The advantage of permeate chamber is: when fixed leg 25 extrudes rubber tube 24 downwards, permeate chamber can not form resistance to fixed leg 25.Preferred, permeate chamber is humanoid chamber, and humanoid chamber can block the top in fixed leg 25 uniformly.
In the present embodiment, preferably, the cavity 26 be positioned at below fixed leg 25 comprises the first chamber and the second chamber that are positioned at axial two ends on rubber tube 24, first chamber and the second chamber are blind hole, and namely the first chamber is not communicated with the second chamber, are blind hole, the effect that hole below fixed leg 25 is set to blind hole is, at rubber tube 24 by the Recovery Process after compressing, the chamber wall energy between the first chamber and the second chamber is enough provides actv. power for replying, and prevents rubber tube 24 by conquassation.Preferred, the first chamber and the second chamber are in-line chamber, and in-line chamber is convenient to manufacture.
In the present embodiment, further, the position that contacts with sleeve 23 bottom rubber tube 24 offers groove 29.When fixed leg 25 extrudes rubber tube 24, contact bottom rubber tube 24 with sleeve 23, the extruding degree that it is subject to is heavier, offers groove 29 herein to alleviate rubber tube 24 deformation extent, prevents conquassation.
The present embodiment also provides a kind of automobile, comprises operator's compartment assembly, and operator's compartment assembly comprises longitudinal floor beam 27 and bracket assembly 28, also comprises above-mentioned operator's compartment shock absorption suspension device, and longitudinal floor beam 27 is overlapped on rubber pad 22, and sleeve 23 is fixed on bracket assembly 28.
Because above-mentioned operator's compartment shock absorption suspension device has above-mentioned technique effect, the automobile comprising this operator's compartment shock absorption suspension device also should have corresponding technique effect.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
