Abstract
The invention belongs to the field of farm vehicles, and in particular discloses a rear axle assembly of a farm vehicle for agricultural cultivation and field running. The rear axle assembly comprises a rear axle which is provided with a brake disc seat and a chain wheel seat, wherein a brake disc is fixed on the brake disc seat; a chain wheel is fixed on the chain wheel seat; adjusting mechanisms are respectively mounted on the sides of the brake disc and the chain wheel on the rear axle, and matched with the rear axle by a bearing; the adjusting mechanisms are fixed to a rear shaking rack of a main frame of the farm vehicle; and connecting discs are mounted at two ends of the rear axle. The rear axle assembly of the farm vehicle disclosed by the invention has the advantages that an eccentric bearing block is adjusted to achieve the purpose of adjusting the distance from the rear axle to an engine to further adjust the tension of a transmission chain; the stability and the safety in using the farm vehicle can be improved; and the transmission chain can be prevented from falling.
Description
Technical field
The invention belongs to the agri-vehicle field, specifically is the farm vehicle back axle assembly that is used on a kind of farm vehicle that farmers' cultivates, start in the field.
Background technology
At present, the structure of three-wheel tractor, walker tractor and small four-wheel tractor is original, backward, and serviceability is single, and safety performance is poor especially.Three-wheel tractor is simply to transport vehicle, the non-constant of its safety performance, walker tractor can transport and can agro-farming, but owing to be reversing sense, cause it all not fully up to expectations in transportation and agro-farming, drive as playing acrobatics, cultivated land is as the instruction ox, in the process of carrying out agro-farming, cause some driver to suffer from the injury of rotovator, harmfulness is very big.Small four-wheel tractor is the hard transmission of articulated steering, transportation is during goods, drives hard especially, and dangerous, in climbing and descending process, owing to the reason of articulated steering causes driving very difficult, tend to lead to traffic accident, connect rotovator after, gravity unbalance, make front-wheel lighten, direction is difficult to control, the inconvenience of turning.There is great security risk in above-mentioned three kinds of vehicles, exist simultaneously and use inconvenient, the uncomfortable white of asking, along with addressing the above problem, four-wheel spark ignition engine farm vehicle has appearred, but because that messenger chain appears in farm vehicle working environment complexity easily is loosening, owing to existing farm vehicle messenger chain can't be regulated and uses instability.
Summary of the invention
The problem to be solved in the present invention is that the farm vehicle messenger chain can be regulated, and therefore the present invention proposes a kind of farm vehicle back axle assembly.
The present invention has adopted following technical scheme:
The farm vehicle back axle assembly, it comprises rear axle, rear axle is provided with brake disc seat and chain pulley seat, brake disc is fixedly arranged on the brake disc seat, sprocket wheel is fixedly arranged on the chain pulley seat, be equipped with regulating mechanism in the side of brake disc and the side of sprocket wheel on the rear axle, cooperate by bearing between rear axle and the regulating mechanism, regulating mechanism is fixed on the back reel cage of farm vehicle main car frame, and the two ends of rear axle also are equipped with terminal pad.
Described regulating mechanism comprises eccentric bearing block and anchor ear combination, and the anchor ear combination comprises anchor ear and following anchor ear and secure component, and eccentric bearing block is locked by secure component closed back between last anchor ear, following anchor ear.
Described terminal pad is fixed on the back shaft end by packing ring and jam nut, is provided with spring cotter between jam nut and the rear axle, and the rear axle spindle nose is provided with axle sleeve.
Described brake disc seat end face passes through nut locking.
Described chain pulley seat end face passes through nut locking.
Described eccentric bearing block is provided with two adjustment holes.
Advantage of the present invention is to reach the purpose that the distance of regulating rear axle and driving engine reaches adjusting messenger chain degree of tightness by regulating eccentric bearing block, has improved stability and safety that farm vehicle uses, prevents that messenger chain from coming off.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the farm vehicle back axle assembly, it comprises rear axle 8, rear axle 8 is provided with brake disc seat 7 and chain pulley seat 9, by bolt 16 brake disc 6 is arranged fixedly on the brake disc seat 7, brake disc seat 7 one end faces are spacing by the step on the rear axle 8, the other end is by nut 5 lockings, 9 one end faces of chain pulley seat are also spacing with the step on the rear axle 8, another end face passes through nut locking, this nut is left-handed nut 10, by bolt 14 sprocket wheel 15 is arranged fixedly on the chain pulley seat 9, be equipped with regulating mechanism in the side of brake disc 6 and the side of sprocket wheel 15 on the rear axle 8, cooperate by bearing 17 between rear axle 8 and the regulating mechanism, bearing 17 sides are provided with adjusting pad 13, regulating mechanism is fixed on the back reel cage of farm vehicle main car frame, the two ends of rear axle 8 also are equipped with terminal pad 3, are provided with spacing sleeve 11 between terminal pad 3 and the regulating mechanism, and trailing wheel is fixed on the terminal pad 3 by bolt 12.
In the above-mentioned embodiment, regulating mechanism can comprise eccentric bearing block 4 and anchor ear combination, and the anchor ear combination comprises anchor ear 20 and following anchor ear 21 and secure component, and eccentric bearing block 4 is locked by secure component closed back between last anchor ear 20, following anchor ear 21.
In the above-mentioned embodiment, terminal pad 3 is fixed on rear axle 8 ends by packing ring 18 and jam nut 2, is provided with spring cotter 19 between jam nut 2 and the rear axle 8, and rear axle 8 spindle noses are provided with axle sleeve 1.
In the above-mentioned embodiment, eccentric bearing block 4 is provided with two adjustment holes.
Principle of the present invention is to be located in the eccentric orfice of eccentric bearing block by rear axle, just rear axle can be approached during the eccentric rotation axis bearing like this or away from driving engine, thereby sprocket wheel just follows rear axle to approach or reach away from driving engine the degree of tightness of the messenger chain between adjusting sprocket wheel and the driving engine, form combination by upper and lower anchor ear and secure component, eccentric bearing block is rotated or fixing.
