The utility model discloses a balance shaft axle casing assembly for a four U-bolts used by a breakaway compensating axle suspension, and the balance shaft axle casing assembly comprises a bracket, a balance shaft and a balance axle casing. One end of the balance shaft is fixed to the bracket, while the other end of the balance shaft is rotatablely connected with the balance axle casing; wherein, the balance axle casing has four U-bolts symmetrically distributed at both sides along the central line of the balance axle casing. The neck of the balance axle casing is connected with a flat spring; both the flat spring and a pressed compact of the flat spring are fixed to the balance axle casing through the U-bolts. The external ends of the U-bolts are tightened through a self-lock nut. The balance shaft is connected with the balance axle casing through a spherical bearing. The U-bolt neck of the balance axle casing of the utility model is added from two to four, thereby improving the maintainability and the reliability of the vehicles, ensuring the safety of drivers and maintainers, eliminating the interference point of original suspension fork, and prolonging the service life of relative components of a drive axle.
Description
Technical field
The utility model discloses the balance shaft tape spool housing assy of four saddle clamps that a kind of breakaway-element balance suspension uses, and belongs to automobile with balance shaft assembly class technical field.
Background technology
The core component of automobile balance suspension system is a balance shaft assembly, and the breakaway-element balance suspension balance shaft assembly of original design has only a kind of specification, and can only assemble two saddle clamps, and a side has only one.When this assembly was used on the large-scale dumping car, owing to reasons such as heavy duty and road conditions differences, saddle clamp was easy to fracture failure, and saddle clamp fracture back vehicle loses driving functions, must carry out heavy duty on the spot at the stagnation of movement place and repair.The heavy duty genus dangerous operation that repairs threatens to maintainer's personal safety easily, and is difficult to guarantee repair quality.In addition, if saddle clamp when fracture speed of a motor vehicle is higher or road conditions are relatively poor, then be easy to overturn, this directly threatens driver and crew's life security and cargo security.
Summary of the invention
Be used for the deficiency of large-scale dumping car at existing balance shaft assembly structure, the utility model provide a kind of carry big, simple in structure, produce and assembling easily, dependable performance, be specifically designed to the balance shaft assembly of four saddle clamps of large-scale dumping car.
The utility model is achieved through the following technical solutions:
The utility model comprises support, balance shaft and balance shaft housing, and balance shaft one end and support are fixed, and the other end and balance shaft housing are rotatably connected, and wherein, the saddle clamp draw-in groove of described balance shaft housing is four, the both sides that are distributed in the balance shaft housing line of centers of symmetry.
Also be connected with leaf spring in the draw-in groove of described balance shaft housing, leaf spring and leaf spring briquetting are fixed on the balance shaft housing by saddle clamp, and the outer end of saddle clamp is fastening by self lock nut.
Described described balance shaft is connected by globe bearing with balance shaft housing.
The saddle clamp draw-in groove of the utility model balance shaft housing increases to four by two, for fear of since increased saddle clamp that cause with interference support and support binding bolt, close binding bolt changes hexagon socket countersunk flat cap head screw into by hex bolt, and supporting structure also redesigns.The beneficial effects of the utility model are: original balance shaft assembly has compact conformation, cost is low, performance good, carrying is big, simple in structure, is convenient to advantages such as production and installation.Owing to eliminated the interference point of original suspension, the jerk value of back axle significantly strengthens in making, so just greatly reduces drive axle because of spacing frequency of transshipping, thereby has prolonged the service life of drive axle associated components.Owing to the perfection coupling with leaf spring, rubber plinth makes the impact resistance of vehicle and ride comfort improve greatly, strengthen occupant's traveling comfort again, reduced the probability of damage of goods, improved the reliability and the life-span of vehicle frame.The utility model is on the basis of having inherited former assembly advantage, improve at the deficiency that former assembly is applied on the human-like dumping car, balance shaft assembly after the improvement can improve load-carrying capacity and system reliability greatly, improve the vehicle maintainability, ensured the life security of driver and crew and service personnel.
