Description
Technical field
The invention belongs to light card operator's compartment rear support structure, be specifically related to a kind of novel operator's compartment rear support structure with topping up rubber cushion.
Background technology
Light card operator's compartment rear support mechanism is all the form adopting left and right to be separated substantially at present, and left and right rear support is separate, is separately fixed on the left-right longeron of vehicle frame.Operator's compartment realizes vibration damping by automobile cab rubber rubber cushion traditional in rear support suspension.
Because left and right rear support is separated, left and right rear support spacing easily by the impact that vehicle frame is opened, causes operator's compartment and ship type support to be interfered outward.Traditional automobile cab rubber rubber cushion suspension is bad for the vibration isolating effect of low frequency and high-frequency vibration.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of operator's compartment rear support structure.
Technical scheme of the present invention is as follows:
A kind of operator's compartment rear support structure, comprising:
Pipe boom support, comprises U-shaped pipe and footing bearing, and the two ends that described footing bearing is fixed on U-shaped pipe play a supportive role;

Rubber cushion, is fixed on described pipe;
Little boat supporting frame, is fixed on described rubber cushion.
Preferably, the tube wall of described U-shaped pipe is provided with pit.
Preferably, support frame as described above comprises the arc fixed arm be fixedly connected with described pipe and the upper hold-down arm be fixedly connected with described footing bearing and lower support arm, described arc fixed arm and pipe are concentric structure, and described upper hold-down arm is fixedly connected with the two ends of fixed arm with lower support arm.
Preferably, described lower support brachium is in upper hold-down arm, and described arc fixed arm is major arc fixed arm.
Preferably, described rubber cushion is circular rubber cushion, and the diameter of its diameter and described pipe matches.
Preferably, described rubber cushion is topping up rubber cushion.Institute's topping up body is water and ethylene glycol mixture, which ensure that can to use under psychro-environment.
Preferably, described little boat supporting frame is made up of latch hook fixed pin shaft and ship type bracket mounting face.
Preferably, described supporting construction also comprises draw ring and/or mud guard erecting frame, and described draw ring and/or mud guard erecting frame are arranged on described rubber cushion bracket.Described mud guard erecting frame is for installing mud guard, and described draw ring is used for coordinating with the safety hook of lockable mechanism, and safety hook hangs over the safety measures as locking mechanism for cab on draw ring.
Beneficial effect of the present invention is as follows:
1, the present invention adopts integral tube girder construction, ensure that left and right rear support spacing not by the impact that vehicle frame is opened outward.Pipe boom support of the present invention adopts tubular structure, effectively enhances its anti-torsion performance; Described U-shaped pipe and two ends footing bearing are welded into a basket type structure, add structural strength; U-shaped pipe with the addition of pit feature, improve U-shaped pipe anti-bending strength.Described rubber cushion bracket adopts the form of bracket welding pipe, and bracket support face exceedes the pipe center of circle, improves the stability of rubber cushion; Rubber cushion press-fits into pipe simultaneously, is limited the installation site of rubber cushion, ensure that setting accuracy by pipe.The present invention adopts pipe boom support to come connecting vehicle frame two ends, and as the installation carrier of little boat supporting frame.Little boat supporting frame and bottom plate of driving cab rear support panel beating profile are fitted, and by rubber cushion blocks damping.Because little boat supporting frame is fixed on integral tube boom support, so outer of vehicle frame does not affect left and right rear support spacing, improve assembly precision;
2, the present invention adopts novel topping up rubber mat structure to have obviously advantage compared with traditional automobile cab rubber damping device: low frequency phase obtains higher dynamic stiffness and good damping and limits low frequency and significantly vibrate; The high frequency stage reduces the high frequency dynamic stiffness of hydraulic mount by the effect of decoupling zero passage, eliminates dynamic hardening phenomenon, improves vibration isolation efficiency;
In a word, the present invention adopts integral tube girder construction, ensure that left and right rear support spacing not by the impact that vehicle frame is opened outward.There is provided a kind of brand-new topping up rubber cushion to suspend and replace traditional automobile cab rubber rubber cushion suspension, fundamentally solve the damping noise reduction problem of automobile cab.By using topping up rubber cushion can effectively suppress the low frequency of operator's compartment significantly to vibrate, eliminating the high frequency noise in operator's compartment simultaneously, improving the travelling comfort of vehicle.
