Abstract

The utility model belongs to front axles of small tractors, which comprises two front wheel assemblies (1), two turning knuckles (11), two vertical shafts (4), a turning transverse pull rod assembly (9), two turning arms (7), a front shaft (8) and two vertical shaft sleeves (6). The utility model is characterized in that the utility model also comprises two springs (5) which are sheathed on the vertical shaft sleeves (6) and are positioned in the vertical shafts (4). The utility model has the advantages of simple structure, convenient assembly, high shock absorption and low cost increase. Besides, a tractor body has high stability.

Description

The propons of trac.

The utility model relates to a kind of propons of trac., especially a kind of propons of small four-wheel tractor.

At present, the propons of small four-wheel tractor can be divided into two classes basically: the one, and the rigidity propons, this propons is simple in structure can be adapting to the needs of low speed operation, but because of not eliminating from ground-surface impact, easily cause driver fatigue and discomfort; Simultaneously seriously easily cause the fault at body and propons position to influence its life-span because of jolting.The 2nd, be the elasticity propons of damping means with the steel spring, the steering hardware of this class propons is identical with preceding class, the middle part that installs steel spring in the top or the bottom of front axle just, the two ends load of leaf spring is in frame, though this class elasticity propons can reduce the vibration of jolting, the deficiency that assembling is complicated, the cost increase is more is arranged.

The purpose of this utility model in order to overcome defective and the deficiency that above-mentioned farm tractor front axle exists, provides a kind of effectiveness in vibration suppression better exactly, assembles propons easy, that cost increases less small four-wheel tractor.

The technical solution of the utility model is: a kind of propons of trac., and it comprises two preceding wheel assemblies, two steering swivels that are installed on the front-wheel, two vertical shafts that are loaded on the steering swivel; A tierod assembly, the spindle arm that two one ends are loaded on the vertical shaft, the other end connects with tierod assembly two ends strand respectively, a front axle, two vertical shaft sleeves that are connected with the front axle two ends respectively, it is characterized in that it also comprise two respectively block set on vertical shaft, be positioned at the spring of vertical shaft sleeve.

Figure of description is the horizontal cross-sectional schematic of the structure of the utility model embodiment (having omitted identical with it right side partly).1 is preceding wheel assembly among the figure, the 2nd, and dust boot, the 3rd, upper sliding sleeve, the 4th, vertical shaft, the 5th, spring, the 6th, vertical shaft sleeve, the 7th, spindle arm, the 8th, front axle, the 9th, the tierod assembly, the 10th, wave axle, the 11st, steering swivel, the 12nd, rubber cushion, the 13rd, gland, the 14th, seal ring, the 15th, low sleeve, the 16th, spring mattress.

The utility model is described in further detail below in conjunction with embodiment: at first preferably be equipped with at front axle 8 middle parts with the bindiny mechanism of frame and wave axle 10, promptly preferably keep the axle that waves of former rigidity propons, to keep the orthostatic of body; The second, in vertical shaft sleeve 6 inboard upper and lower parts upper and lower sliding sleeve 3 and 15 are housed respectively preferably, the wearing and tearing when reducing to jolt during the upper and lower motion of the opposed axle sleeve of vertical shaft; And dust boot 2 preferably is housed in the upper end of vertical shaft sleeve 6, with dust protection with play a part attractive in appearance; Gland 13 preferably is equipped with in lower end at vertical shaft sleeve 6; The 3rd, preferably install spring mattress 16 in the lower end of spring 5, preferably install rubber cushion 12 on the top of steering swivel 11, to avoid rigidity collision, the buffer action when playing compression limit; The 4th, when implementing the utility model, between low sleeve 15 and vertical shaft 4, preferably be provided with the seal ring 14 that prevents leakage of oil.

To sum up, the utility model is than prior art, has simple in structurely, easy to assembly, subtracts Shaking property, body stationarising, the advantage that the cost increase is littler and good effect are worth pushing away The wide use.
