Abstract
The utility model relates to the structure of a front bridge of a tractor, which comprises a swing shaft, wherein an independent right bridge arm and a right bridge arm are hinged on the swing shaft, a plate spring seat which can rotate is sheathed on the swing shaft, plate spring components are fixed under the plate spring seat and both ends of the plate spring components are connected with the left bridge arm and the right bridge arm through lifting lugs respectively. Because the independent hanging front bridge of a tractor has better shock absorbing performance, the comfort of drive is increased and the service life of components is extended.
Description
The utility model relates to the preceding bridge construction of trac..
Existing small four-wheel tractor, its propons all is to adopt rigidity propons or non-independent suspension propons, its cushioning performance is bad, when carrying out hauling operation, because small towns, at village level road are subjected to the restriction of objective condition, the road surface often is uneven, and chaufeur is sitting on the small four-wheel tractor and travels, not only the hardship of jolting to be born, and the infantile failure of machine part can be caused.
The purpose of this utility model is the trac. independent suspension propons of a kind of energy of design vibration damping.
This trac. independent suspension propons comprises and waves axle, its constructional feature is to be hinged with independently left brachium pontis, right brachium pontis on the axle and to be set with rotary spring block waving, the below of spring block is fixed with lead spring assembly, the left end of lead spring assembly links together by left hanger and left brachium pontis, and the right-hand member of lead spring assembly links together by right hanger and right brachium pontis.
In order to strengthen the reliability of independent suspension propons, also be set with rotary left brace panel and right brace panel on the axle waving, the end of left brace panel is captiveed joint with left brachium pontis, and the end of right brace panel is captiveed joint with right brachium pontis.
During installation, the front axle carrying sleeve of trac. is contained in waves on the axle, the outer end of left brachium pontis is connected with the near front wheel assembly of trac., and the outer end of right brachium pontis is connected with the off front wheel assembly of trac..
This trac. independent suspension propons, front axle assy can rotate around waving axle, makes front axle assy have the performance of waving.Left side brachium pontis, right brachium pontis are independent mutually, and can rotate respectively around waving axle.When trac. was static, the weight that trac. is distributed on the propons was delivered on the front-wheel of the left and right sides by waving axle, spring block, lead spring assembly, left and right sides hanger, left and right sides brachium pontis.When big vibration takes place trac., absorb vibrational energy around the rotation of waving axle and left brachium pontis, the rotation respectively of right brachium pontis and the elastic deformation of lead spring assembly by front axle assy; When little vibration takes place trac., absorb vibrational energy by the rotation respectively of left brachium pontis and right brachium pontis and the elastic deformation of lead spring assembly; When one of them takes turns the generation vibration, absorb vibrational energy by the rotation of a pairing brachium pontis and the elastic deformation of lead spring assembly.From the above mentioned, this trac. independent suspension propons can be realized the vibration damping purpose well, has improved driver comfort, has prolonged the service life of parts.
Accompanying drawing shows the embodiment of trac. independent suspension propons, and wherein Fig. 1 is the front view of embodiment, and Fig. 2 is the birds-eye view of embodiment, and Fig. 3 is the A-A section-drawing of Fig. 1.
In the present embodiment, trac. independent suspension propons comprise wave the axle 5, wave on axle 5 the surface and have oil groove 13, be hinged with independently left brachium pontis 1 on 5 waving axle, right brachium pontis 9, be set with rotary spring block 2, left side brace panel 7, preceding bracing strut 14 on right brace panel 8 and the trac., the below of spring block 2 is by pressing plate 4, bolt 6 is fixed with lead spring assembly 3, the left end of lead spring assembly 3 links together with left brachium pontis 1 by left hanger 11, the right-hand member of lead spring assembly 3 links together with right brachium pontis 9 by right hanger 12, ways of connecting is to be fixed together by bearing pin 10, the end of left side brace panel 7 is captiveed joint with left brachium pontis 1 by bolt, and the end of right brace panel 8 is captiveed joint with right brachium pontis 9 by bolt.
