Description
Technical field
The utility model relates to a kind of high-mobility, multipurpose, wheeled vehicle trac..
Background technology
Trac. is a kind of modernized field machine of not only being engaged in farmland operation but also being engaged in over-the-road transportation, but trac. user's actual use present situation is at present, the large and middle tractor more than 50 horsepowers that the peasant purchases mainly is based on farmland operation, on the period of service of trac., mainly be to carry out farmland operation in summer, two seasons of autumn, the whole year, period of service was less than 3 months altogether, and the trac. warehouse-in was sealed up for safekeeping after receipts were planted and finished season, caused to reach the long-term machinery waste of leaving unused of 9 wheat harvesting periods the whole year.Because the unit of trac. transportation at present is engaged in the trailer of over-the-road transportation traction, mainly traction is mid-shaft type trailer and traction rod-type trailer, low because of appraising and deciding traction charge material amount tonnage, the transportation of trac. user upper track road is often imposed a fine because of overload, the riding stability difference often causes safety misadventure hidden danger in addition, objectively directly influenced the enthusiasm that the trac. user is engaged in the hauling operation of setting out on a journey, made the idle for a long time major cause of trac..
Cause trac. to appraise and decide the low major cause of the specified traction quality tonnage of transportation, because present widely used trac. transportation draw gear technical pattern causes, GB7258-2004, national standard technical requirementss such as GB16151.1-2008 regulation, it is the trailer maximum autohrozed total mass that the extension of wheel-tire tractor transportation unit drags mass ratio and the ratio of trac. service property (quality) should be not more than 3, because the draw gear of the unit of trac. transportation at present mostly is fully-trailed, the traction of trac. main frame mainly is traction rod-type trailer in addition, the connecting mode of its trac. and trailer all is by bearing pin main frame rear portion hauling hook and trailer towing loop chain to be connect, this structure has just determined following two problems of fully-trailed trac. transportation unit: the one, and the low hauling operation cost height that causes of charge material amount, because the service property (quality) of trac. is determining to transport the charge material amount of unit, because traction rod-type trailer does not have vertical load and acts on the trac. main frame, the service property (quality) of trac. can not increase with the increase of trailer charge material amount; The 2nd, riding stability is poor, side direction particularly easily takes place in the road loading transport driving to deflect, especially the steering handwheel of the triangle drawbar frame direct connection trailer front axle of draw bar trailer top swings greatly, in shipping goods travels when running into emergency brake or descending, since the steering handwheel front axle triangle drawbar frame of load-carrying draw bar trailer to the haulage tractor main frame form about bump, cause additional impact power to trac., very easily cause trac. main frame wigwag motion out of control, car takes place turn over the grave accident that the people dies and cause the great economy property damage.
