Abstract
The utility model discloses a small-sized tractor carriage with a front wheel driving steering gear, which is formed by the modification of a small-sized tractor. The utility model is composed of an engine, a driving system, an operating mechanism, tyres, a driving cabin and a carriage. With the adoption of a disconnecting type steering driving axle structure, the torque is transmitted by power to a front wheel hub to drive the front wheel to rotate through a final drive box and a universal joint driving shaft. Using the disconnecting type steering trapezium structure to realize the front wheel steer, the utility model overcomes the inherent structural defects of big operation force of articulated steering and laborious steering. The front wheel adopts a spiral spring independent suspension structure with double pendulum arms with unequal lengths, so the utility model has the advantages of small quality of non-spring loading, reduced vibration loading and improved riding comfort. The service life of the tractor carriage is enhanced visibly.
Description
The utility model relates to a kind of power car, particularly a kind of transport plane that is formed f-w-d, turned to by the compact tractor modification.
At present, compact tractor modification transport plane chassis commonly used is connected by the radial type draw gear with trailer, mostly is f-w-d, articulated steering structure greatly.Because the front axle of this transport plane does not have shock absorption device, change speed gear box and final transmission gearbox also will directly stand the ground-surface impulsive force except bearing the load of complete machine quality, and the vibration of travelling is big, and riving condition is abominable, the parts sensitive for damages.Some type adopts the steel spring of device shock-absorbing between chassis side rail and steering drive axle axle housing, and this structure can not reduce nonspring carried mass, does not reduce the impact load of road surface to change speed gear box, thereby can not reduce vibration, improves driver comfort.In addition, also exist the inherent structure shortcoming that the articulated steering actuating force is big, drive effort.
The purpose of this utility model is to provide a kind of f-w-d, turns to, the compact tractor modification transport plane of ride comfort safety.
The purpose of this utility model is achieved through the following technical solutions: f-w-d employing breakaway-element turns to, the drive axle structure, the inner shaft that is final transmission gearbox links to each other with an end of universal joint shaft by terminal pad, and the other end of universal drive shaft links to each other with front-wheel hub by flange.Power passes to moment of torsion on the front-wheel hub through final transmission gearbox, universal joint shaft, drives front-wheel and rotates.Front-wheel steering is a breakaway-element steering trapezium structure, and promptly intermediate rod is contained between plumbing arm and the inertia arm, and plumbing arm, inertia arm are connecting a lateral bracing strut separately, and each lateral bracing strut is connected with steering swivel by spindle arm respectively.
Intermediate rod, plumbing arm and inertia arm three form planar linkage mechanism, and when guaranteeing the plumbing arm swing, intermediate rod has only translation and do not have swing, and the lateral bracing strut that moves through of intermediate rod is passed to the deflection of spindle arm drive front-wheel, realizes front-wheel steering.Front-wheel adopts not isometric double-pendulum arms coil spring independent suspension structure, be that top link, following swing arm the inner link to each other with vehicle frame, the outer end of upper and lower swing arm links to each other with the upper and lower end of steering swivel, steering swivel with connect the dish link to each other, connect dish and support front-wheel hub, place coil spring between carriage spring bearing and the top link.
The utility model with f-w-d, turn to and substituted original f-w-d, articulated steering, and front-wheel adopts not isometric double-pendulum arms coil spring independent suspension structure, therefore nonspring carried mass is little, alleviated vibrational load, turn to light and flexible, improved riding comfort, road shocks power no longer directly passes to final transmission gearbox, improve the stress condition of final transmission gearbox, improved the service life of transport plane.
Accompanying drawing 1 is a kind of complete machine structure scheme drawing of the utility model.
Accompanying drawing 2 turns to for a kind of breakaway-element, the structural representation of drive axle.
Accompanying drawing 3 is a kind of breakaway-element steering trapezium structural representation.
Accompanying drawing 4 is a kind of power take-off implement scheme drawing of the utility model.
With reference to accompanying drawing 1～4, driving engine (1) is selected S195 or S1100 diesel engine for use.Unit frame (6) hangs (9), forward and backward wheel (8), (10) after with driving engine (1), breakaway-element tie rod linkage (2), not isometric double-pendulum arms coil spring independent suspension (3), change speed gear box (4), operator's compartment (5), railway carriage (7), steel spring and breakaway-element turns to, drive axle (11) etc. is combined integrated.The live axle of final transmission gearbox is shortened and be designed to the inner shaft (21) of wounded in the battle key, and universal joint shaft (19) adopts the double universal joint pin cardan joint transmission shaft.Upper and lower swing arm (18), (22) connect for bearing pin with vehicle frame (6).Save the former chain gear case of f-w-d, articulated steering transport plane.The oil pump (32) of goods of will being used to remove stage makeup and costume is fixed on the left longeron of vehicle frame (6), oil pump disconnector (31) is being adorned in change speed gear box input shaft (30) end, stir disengaging bar, oil pump disconnector (31) and oil pump (32) engagement or disengagement, railway carriage (7) lifts or falls, and finishes the loading and unloading of goods.
