Abstract
The utility model provides a driver's cabin gasbag shock absorber, it includes the shock absorber, and the shock absorber suit is in the gasbag, and the top of shock absorber is connected with the lug, and the bottom of shock absorber is connected with the pin, and the cover is equipped with two flexible stop devices in the pole portion of pin, flexible stop device and the pole portion sliding connection of pin, and the pole portion lower extreme of pin still overlaps and is equipped with the nut. The utility model discloses adopt cotter formula mounting structure at the shock absorber lower extreme, the vertical installation of shock absorber through flexible stop device compression pretension, makes the shock absorber have certain beat rigidity, can effectively avoid the crooked problem of driver's cabin because of the driver's cabin barycenter is not caused at the intermediate position. Additionally the utility model discloses a shock absorber can not only play the damping effect of left right direction, also has fine buffering damping effect to the drunkenness of driver's cabin fore-and-aft direction moreover, uses this novel shock absorber can improve the riding comfort of driver's cabin greatly.
Description
[technical field]
The utility model relates to a kind of auto parts and components, refers to particularly it is a kind of locomotive cab air-bag shock absorber for cab rear suspender.
[background technology]
With reference to figure 1, at present, general steering room back suspension air-bag shock absorber comprises shock absorber 3, on shock absorber 3, be set with air bag 2, the top of described shock absorber 3 and bottom are all connected with hanger 1, and shock absorber 3 carries out hinged installation by hanger 1 and coordinating of bolt, the structure of this two ends radial type, shock absorber can be rotated around bolt, but because operator's compartment centroid position is not generally at midway location, easily there is the problem that operator's compartment is crooked in both sides unbalance stress.Two ends hanger formula structure only has the rotational freedom of a direction, to driving the energy of vibration of left and right directions, plays good damping of vibrations, but bad to the effectiveness in vibration suppression of driving fore-and-aft direction.
[utility model content]
In view of this, be necessary to provide a kind of locomotive cab air-bag shock absorber that can greatly improve the travelling comfort of operator's compartment.
For achieving the above object, the utility model provides a kind of locomotive cab air-bag shock absorber, it comprises shock absorber, described shock absorber is sleeved in air bag, it is characterized in that: the top of described shock absorber is connected with hanger, the bottom of described shock absorber is connected with pin, is set with two flexible limit devices in the bar portion of described pin, the bar portion sliding block joint of described flexible limit device and pin, the bar subordinate end of described pin is also set with nut.
In such scheme:
Described flexible limit device comprises rubber block, upper cover plate and lower cover, and described upper cover plate and lower cover are positioned at the upper/lower terminal of rubber block, and described rubber block, upper cover plate and lower cover are equipped with the through hole for being passed by pin.
The cross section of described rubber block, upper cover plate and lower cover is circle, and the outer of described upper cover plate and lower cover is all connected with the positioning plate towards rubber block bending.
The bar portion of described pin is sleeved in sleeve, and described flexible limit device and nut are installed on sleeve.
The utility model adopts peg type mounting structure in shock absorber lower end, shock absorber is vertically installed, by flexible limit device compression pretension, make shock absorber there is certain beat rigidity, can effectively avoid the operator's compartment skew problem not causing at midway location because of operator's compartment barycenter.
The utility model is owing to adopting flexible limit device to carry out spacing to shock absorber, shock absorber can not only be deflected, fore-and-aft direction also can swing, thereby can make shock absorber can not only play the damping of vibrations of left and right directions, and the play of operator's compartment fore-and-aft direction is also had to good buffer shock-absorbing effect, use this new type vibration isolator can greatly improve the travelling comfort of operator's compartment.
[accompanying drawing explanation]
Fig. 1 is locomotive cab air-bag shock absorber structural representation in prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is assembling schematic diagram of the present utility model.
[specific embodiment]
For understanding better the utility model, below with reference to accompanying drawing, the embodiment of utility model is described in detail.
Existing locomotive cab air-bag shock absorber is explained in detail in background technology as shown in Figure 1, in this, repeats no more.
With reference to figure 2 and Fig. 3, a kind of locomotive cab air-bag shock absorber of the present embodiment, it comprises a cylinder type damper 3, shock absorber 3 is sleeved in air bag 2, on the top of shock absorber 3, is connected with hanger 1, and the bottom of shock absorber 3 is connected with pin 7, upper end hanger 1, shock absorber 3 and lower end pin 7 are integrally welded, in the bar portion of pin 7, be set with two flexible limit devices, the bar portion sliding block joint of flexible limit device and pin 7, the bar subordinate end of pin 7 is also set with nut 9.
During assembling, shock absorber 3 upper ends are penetrated in hanger 1 and are suspended on correlated parts by bolt, make shock absorber 3 and correlated parts hinged; The pin 7 of shock absorber 3 lower ends is first set with a flexible limit device, pin 7 penetrates in the mounting hole of support 11 subsequently, wherein the diameter of pin 7 must be less than the diameter of mounting hole, then is inserted in a flexible limit device, preferably by nut 9, pin 7 and support 11 is locked.
The present embodiment adopts peg type mounting structure in shock absorber 3 lower ends, shock absorber 3 is vertically installed, by flexible limit device compression pretension, make shock absorber there is certain beat rigidity, can effectively avoid the operator's compartment skew problem not causing at midway location because of operator's compartment barycenter.In addition, the utility model is owing to adopting flexible limit device to carry out spacing to shock absorber 3, shock absorber 3 can not only be deflected, fore-and-aft direction also can swing, thereby can make shock absorber 3 can not only play the damping of vibrations of left and right directions, and the play of operator's compartment fore-and-aft direction is also had to good buffer shock-absorbing effect, use this new type vibration isolator can greatly improve the travelling comfort of operator's compartment.
In the present embodiment, flexible limit device comprises rubber block 5, upper cover plate 4 and lower cover 8, and upper cover plate 4 and lower cover 8 are positioned at the upper/lower terminal of rubber block 5, and rubber block 5, upper cover plate 4 and lower cover 8 are equipped with the through hole for being passed by pin 7.
The cross section of the rubber block 5 of the present embodiment, upper cover plate 4 and lower cover 8 is circle, and the outer of upper cover plate 4 and lower cover 8 is all connected with the positioning plate 10 towards rubber block 5 bendings, can prevent that rubber block 5 between upper cover plate 4 and lower cover 8, radial-play occurring.
Bar portion at pin 7 is sleeved in sleeve 6, and flexible limit device and nut 9 are installed on sleeve 6, can reduce like this pin 7 wearing and tearing, increases its strength and stiffness.
The above embodiment has only expressed a kind of embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
