Abstract
The utility model relates to a limited front mudguard device used for a tractor, which comprises a mudguard, a mudguard bracket welding part, a rotating mechanism assembly and a limit stopper; the mudguard is connected with the upper part of the mudguard bracket welding part, the lower part of the mudguard bracket welding part is connected on the rotating mechanism assembly through a bolt, and the rotating mechanism assembly is respectively installed on brackets for a left steering knuckle and a right steering knuckle for a tractor front axle provided with the limit stopper; the front mudguard assembly synchronously rotates during the steering process of the tractor along the front wheel under the actions of pretightening force of the limit sleeve and the torsion spring in the rotating mechanism assembly, and when a certain angle is achieved, the upper parts of the front mudguard assembly stops rotating under the actions of the limit plate and the limit stopper in the rotating mechanism assembly, however, the front wheel continuously rotates; and the device effectively protects the neat local appearance of the tractor, meets the demands of big steering angle and small turning radius of the front wheel of the tractor, and meanwhile, has the advantages of compact structure, simple process and good service performance.
Description
Technical field
The utility model belongs to the trac. field, relate to a kind of can be according to the variation of trac. front wheel angle and the tractor spacing type front mudguard device that rotates synchronously or stop operating.
Background technology
At present, in the various wheel-tire tractors that China produces, what front fender apron had is installed on the farm tractor front axle pontic, and this mounting means front-wheel when tractor steering is thrown thing and can directly be splashed on the body, can not play protective action to trac.; The steering swivel place that then is directly installed on farm tractor front axle that has, front fender apron turns to synchronously with front-wheel during tractor steering, when deflection angle hour because front fender apron and preceding hood or body interference can not further turn to front-wheel, cause the tractor steering difficulty.At this situation, therefore, be necessary to develop a kind of spacing type front mudguard device that can actv. protection trac. influence front wheel steering angle again.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, tractor spacing type front mudguard device that in-use performance is good.
The technical solution of the utility model is: tractor spacing type front mudguard device mainly comprises: mudwing, splash apron bracket soldering member, rotating mechanism assembly, positive stop.Mudwing is connected with splash apron bracket soldering member top, and splash apron bracket soldering member bottom is screwed on the rotating mechanism assembly, and the rotating mechanism assembly is respectively installed on the bearing of left and right sides steering swivel of farm tractor front axle; Propons is provided with positive stop.
The rotating mechanism assembly comprises rotary shaft rack component, torsion spring, rotary shell, joint type forced filling oil cup, guide shaft, positioning plate, stop collar, swinging strut component, through type forced filling oil cup; Bolt together is to the rotary shell bottom successively from top to bottom with stop collar, positioning plate, and swinging strut component bolt together is to the right side of rotary shell; Guide shaft passes spacing hole on the rotary shell and the position-limited trough on the rotary shaft rack component, the two is coupled together, in the position-limited trough on the torsion spring upper end insertion rotary shell, insert in the spacing hole of rotary shaft rack component the lower end, rotary shell upper limit hole one end is equipped with the through type forced filling oil cup, and the rotary shell top is equipped with the joint type forced filling oil cup.
With splash apron bracket soldering member and rotary shell bonded assembly two groups of mounting holes are arranged respectively on the swinging strut component.
Rotary shaft rack component axis upper side has position-limited trough, and lower floor has the torsion spring spacing hole that is arranged in the axis circumferencial direction.
Upper end, rotary shell middle part is provided with spacing hole, and right flank is provided with position-limited trough.
The utility model adopts the good effect that produces after the technique scheme to be: protected the local appearance of trac. clean and tidy; satisfied the big deflection angle of wheel-tire tractor front-wheel; the demand of little Turning radius, this front fender structure compactness, technology are simple, economical and practical simultaneously, are worthy of promotion and application.

The specific embodiment
As Fig. 1～shown in Figure 4, tractor spacing type front mudguard device mainly comprises: mudwing 1, splash apron bracket soldering member 2, rotating mechanism assembly 3, positive stop 4.Mudwing 1 is connected with splash apron bracket soldering member 2 tops, and splash apron bracket soldering member 2 bottoms are screwed on the rotating mechanism assembly 3, and rotating mechanism assembly 3 is respectively installed on the bearing of left and right sides steering swivel of farm tractor front axle 5; Propons 5 is provided with positive stop 4.
Rotating mechanism assembly 3 comprises rotary shaft rack component 6, torsion spring 7, rotary shell 8, joint type forced filling oil cup 9, guide shaft 10, positioning plate 11, stop collar 12, swinging strut component 13, through type forced filling oil cup 14; Bolt together is to rotary shell 8 bottoms successively from top to bottom for stop collar 12, positioning plate 11, and swinging strut component 13 bolt togethers are to the right side of rotary shell 8; Guide shaft 10 passes the spacing hole of upper end, rotary shell 8 middle parts setting and the position-limited trough that rotary shaft rack component 6 axis upper sides are provided with, and the two is coupled together, and has guaranteed that rotary shell 8 and rotary shaft rack component 6 can not relatively move on the height direction.Torsion spring 7 upper ends are inserted rotary shell 8 right flanks and are provided with in the position-limited trough, insert in the spacing hole of rotary shaft rack component 6 lower end, torsion spring 7 has certain predetermincd tension after installation, in conjunction with stop collar 12, guaranteed static relatively between rotary shell 8 and the rotary shaft rack component 6.Rotary shell 8 upper limit holes one end is equipped with through type forced filling oil cup 14, and rotary shell 8 tops are equipped with joint type forced filling oil cup 9, can add oil injecting lubricating in cavity, thereby reduce friction, have improved service life.
With splash apron bracket soldering member 2 and rotary shell 8 bonded assemblys two groups of mounting holes are arranged respectively on the swinging strut component 13, satisfy trac. and select the tire of different model and the needs of disalignment distance for use.Rotary shaft rack component 6 lower floor axis circumferencial directions are provided with the torsion spring 7 that torsion spring spacing hole is used to cooperate different model, can satisfy the needs of the different deflection angles of trac..
During tractor steering, the front fender apron assembly rotates synchronously with front-wheel under the effect of stop collar 12 and torsion spring 7 predetermincd tensions, when reaching certain angle, positioning plate 11 on the rotating mechanism assembly 3 is stopped by the positive stop on the propons 54, front fender apron assembly top stops operating, the predetermincd tension of torsion spring 7 further strengthens, stop collar 12 separates with rotary shaft rack component 6, but front-wheel still is rotated further, thereby satisfied the big deflection angle of wheel-tire tractor front-wheel, the demand of little Turning radius has been avoided the interference of front fender apron and preceding hood and body.
