Abstract
The utility model relates to a saddle traction seat support, including support housing, rubber spring, rubber axle sleeve, the first half of support housing is opened there is the shaft hole, and it has the through-hole to open at this shaft hole direction of the inside perpendicular to of support housing, and rubber spring places in this through-hole, and rubber axle sleeve is placed and is installed in the shaft hole through the cooperation on rubber spring. The load caused by jolting vibration and torsional vibration of the semitrailer in the driving process is absorbed and transmitted through the rubber shaft sleeve and the rubber spring, the maximum torsional force transmitted through the saddle type traction seat is reduced, and the rigid impact of the vertical load on the saddle type traction seat support and a tractor frame is reduced, so that the structural damage of the saddle type traction seat support is effectively avoided, and the service life of the saddle type traction seat support is prolonged.
Description
Technical field
The utility model relates to the draw gear of semi-dragging truck, specifically refers to a kind of saddle traction seat support.
Background technology
The saddle traction seat generally is fixed on the tractor truck chassis frame by its support, and traction seat allows different degree of freedom at support.Tradition single degree of freedom saddle traction seat can be done vertical swing around the saddle axis of pitch, the swing of the direction of namely driving a vehicle, this traction seat support mainly adopts the rubber axle sleeve to play damping, buffering effect (as Fig. 7), is applicable to the high barycenter superimposed trailer of high speed, underloading that travels at better highway.And draw big part class, liquid state, the chemical industry class, during the contour torsion stiffness superimposed trailer of powder jar class vehicle, or when meeting with the road conditions difference, the moment of torsion that torsion oscillations and the vibration of jolting bring, torque and load vertically downward transmit between tractor truck chassis and superimposed trailer by the saddle traction seat, bring great rigid shock for saddle traction seat support, this kind rigid shock major part vertically downward, because the effect of rubber axis cover is limited, often cause rubber axle sleeve breakage (as Fig. 8), saddle traction seat support permanent deformation, cracking, inefficacy waits the structural failure problem, has reduced the service life of saddle traction seat support.
Summary of the invention
Order of the present utility model will overcome above-mentioned deficiency exactly, and a kind of saddle traction seat support of long service life is provided.
For achieving the above object, the saddle traction seat support that the utility model is designed, comprise bracket shell, rubber spring, rubber axle sleeve, described bracket shell the first half has axis hole, in bracket shell, have through hole perpendicular to this axis hole direction, described rubber spring is placed in the through hole, directly contact with tractor chassis, buffering by rubber spring, the torque load that superimposed trailer is transmitted reduces, reduced the rigid shock to saddle traction seat and vehicle frame, described rubber axle sleeve is placed on the rubber spring and is installed in the axis hole by cooperation.
Further, described axis hole the first half is semicircle, and the lower part is the oblong identical with this semicircle diameter.
Further, described through hole is up-small and down-big structure, and the through hole hole wall is the conical surface or sphere.
Further, described rubber spring is up-small and down-big bullet.
Further, being provided with two-layered steel plates at least in the middle of the described rubber spring, is rubber between the described firm plate, and this structure has increased rigidity and the reliability of rubber spring.
Further, described rubber axle sleeve bottom is provided with steel plate, has increased rigidity and the reliability of rubber axle sleeve integral body.
The principle of the utility model saddle traction seat support is: when superimposed trailer runs into break turn or road not at ordinary times in the process of moving, can produce huge torsion oscillations, saddle traction seat left and right sides two stands can produce compressive deformation in a small amount, drive the teeter of saddle traction seat assembly, can reduce the rigid shock of vertical load in the vehicle driving process by the damping energy-absorbing function of rubber spring and the effect of automatically replying, reduce the maxim of torsion oscillations power, thereby reduced the torque and the distortion that are passed to tractor chassis by the saddle traction seat, made to have a better suited toughness transition apparatus between tractor truck and the superimposed trailer.
The utility model advantage is: simple in structure, cost is low, and the introducing of elastic element has reduced jolt vibration energy and torsional vibration energy that the traction superimposed trailer transmits in the process of moving; The utility model another one advantage is: the suffered power vertically downward of saddle traction seat support directly is passed to the tractor chassis longeron downwards by rubber axle sleeve, rubber spring, bracket shell does not carry vertical load, bracket shell only is subjected to horizontal drag force, thereby effectively avoided the structural failure of saddle traction seat support, increased the service life of saddle traction seat support.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Saddle traction seat support shown in the figure, comprise bracket shell 1, rubber axle sleeve 2, rubber spring 3, bracket shell 1 has top and is divided into the axis hole 1.1 that the semicircular-shaped lower portion branch is the rectangle structure identical with this semicircle diameter, have the through hole 1.2 of up-small and down-big structure in these axis hole 1.1 directions in bracket shell 1 internal vertical, through hole 1.2 hole walls are the conical surface or sphere, the rubber spring 3 of up-small and down-big bullet structure is placed in the through hole 1.2, directly contact with tractor chassis, at least be provided with two-layered steel plates 3.1 in this rubber spring, preferred six layers of the steel plate number of plies, be rubber between the steel plate 3.1, rubber axle sleeve 2 bottoms also are provided with steel plate 2.2 integral body and are placed on the rubber spring 3 and are installed in the axis hole 1.1 by cooperation.
In the tractor truck traction superimposed trailer driving process, when running into break turn or road not at ordinary times, can produce huge jolt vibration and torsion oscillations, this has applied very big stress just for tractor truck, Trailer type frame for use in vehicle and traction seat, can reduce the twisting resistance that is transmitted by the saddle traction seat by the buffering of rubber spring 3 and the power of automatically replying, thereby reduce rigid shock.In tractor truck traction superimposed trailer driving process, the utility model saddle traction seat support is not subjected to power vertically downward simultaneously, and vertical force directly directly is passed to tractor chassis downwards by rubber axle sleeve 2, rubber spring 3, and bracket shell does not bear vertical load.Such endergonic structure has reduced the rigid shock of the energy that the distraction procedure moderately gusty air vibrates and torsion oscillations brings to saddle traction seat support, thereby has effectively avoided the structural failure of saddle traction seat support, has increased the service life of saddle traction seat support.
