A kind of air shock-absorbing automotive cab rear suspender is disclosed in the Chinese utility model patent of application number CN201220709642.5, comprise air spring vibration reduction device, levelling valve, upper bracket assembly, lower bracket assembly, after cross member and lateral damper, described upper bracket assembly comprises connection bracket, hydraulic lock and middle connection bracket, the described top of upper connection bracket is connected with the bottom of operator's compartment, bottom is successively through hydraulic lock, middle connection bracket, air spring vibration reduction device, be connected with vehicle frame after in the middle part of lower bracket assembly, lower bracket assembly top, after cross member junction is successively by levelling valve mounting bracket, levelling valve, levelling valve adjust bar, be connected with the side wall surface of middle connection bracket after connecting rod rack, the flank end of middle connection bracket is connected with the top of lateral damper, the bottom of lateral damper is connected with the middle part of after cross member.Although this design lateral cushioning performance is good, lateral damper can not play the guiding role, and can not bear side force, can not normal return after operator's compartment rolls.In addition, another commonplace rear suspension structure form is adopted to be substitute lateral damper with lateral connecting rod, lateral connecting rod two ends are connected by rubber bush, although adopt this version to play the guiding role, but there is certain movement interference in vertical direction, and lateral connecting rod is very large on the impact of rigidity in driving cab rear suspension vertical direction, makes the damping effect of air bellow be deteriorated, causes travelling comfort to reduce.
Utility model content
Technical problem to be solved in the utility model is that the deficiency existed for above-mentioned prior art provides a kind of guide wheel type cab rear suspender that can improve ride comfort and require.
The technical scheme that the utility model adopts is: a kind of guide wheel type cab rear suspender, comprise left back supporting component, right back supporting component, portal frame and guidance set, described left back supporting component, right back supporting component structure is identical, both are symmetricly set on the both sides of portal frame, it is characterized in that: described left back supporting component, right back supporting component is all connected with portal frame by guidance set, described guidance set comprises the guiding trestle be fixed in the middle part of portal frame, the bilateral symmetry of guiding trestle is provided with rocking arm, one end of two rocking arms respectively with left back supporting component, right back supporting component is connected, the other end of two rocking arms is rotationally connected with track adjusting wheel respectively, track adjusting wheel slippage is arranged in the chute of guiding trestle, each rocking arm can be moved up and down along the guide groove of guiding trestle.When operator's compartment vertical shake, rocking arm drives track adjusting wheel vertically movement in guiding trestle, and when operator's compartment rolls, rocking arm rotates relative to track adjusting wheel.
By technique scheme, described left back supporting component and right back supporting component include the upper bracket, hydraulic lock, middle link span, the air bellow bumper assembly that set gradually from top to bottom, wherein upper bracket top is fixedly connected with operator's compartment, bottom rotarys connection with hydraulic lock, hydraulic lock bottom is fixedly connected with middle link span, middle link span bottom is fixedly connected with a rocking arm, air bellow bumper assembly top is by rubber bush and middle link span axis hole is hinged, bottom by rubber bush and portal frame axis hole hinged.
By technique scheme, described rocking arm is rotationally connected by rubber bush and track adjusting wheel.
By technique scheme, the center of track adjusting wheel is provided with guiding pivot pin, the both sides of guiding pivot pin are provided with limiting stopper.
By technique scheme, described air bellow bumper assembly comprises air bellow, shock absorber, choker relief valve, air bellow and shock absorber integrated design, regulates rigidity and the cab heights of air bellow by choker relief valve.
Beneficial effect acquired by the utility model is: the utility model is by arranging guidance set, guidance set in this device can play vertical directional tagging, ensure that operator's compartment moves in vertical direction not interfered, thus avoid the impact of guiding mechanism on driving cab rear suspension vertical direction rigidity, guiding trestle can bear side force simultaneously, the inclination of operator's compartment is converted to the displacement in air bellow bumper assembly vertical direction by guidance set, thus effective attenuation rolls the vibration caused, and improves the traveling comfort of driving.
Accompanying drawing explanation
Fig. 1 shaft side figure of the present utility model.
Fig. 2 is the front elevation of Fig. 1.
In figure: upper bracket 1, hydraulic lock 2, middle link span 3, air bellow bumper assembly 4, portal frame 5, rocking arm 6, track adjusting wheel 7, guiding trestle 8, guiding pivot pin 9, limiting stopper 10, guidance set 11.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, present embodiments provide a kind of guide wheel type cab rear suspender, it comprises left back supporting component, right back supporting component, portal frame and guidance set, and left and right rear support assembly is symmetrical, structure consistent, and both are symmetricly set on the both sides of portal frame.
Described left back supporting component and right back supporting component include the upper bracket 1, hydraulic lock 2, middle link span 3, the air bellow bumper assembly 4 that set gradually from top to bottom, wherein upper bracket 1 top is fixedly connected with operator's compartment, bottom rotarys connection with hydraulic lock 2, hydraulic lock 2 bottom is fixedly connected with middle link span 3, air bellow bumper assembly 4 top is by rubber bush and middle link span 3 axis hole is hinged, bottom by rubber bush and portal frame 5 axis hole hinged.Wherein, air bellow bumper assembly 4, comprises air bellow, shock absorber, choker relief valve, air bellow and shock absorber integrated design, regulates rigidity and the cab heights of air bellow by choker relief valve.
