The longitudinal beam of the rear end of the vehicle frame of the utility model is fixed on the sleeve pipe of the half shaft of a rear bridge; the cross beam of the front end of the vehicle frame and a transverse plate spring are connected with a front shaft and are hinged with the tractor frame by a swinging shaft assembly; the rear end of a goods box is hung with the plate spring and is fixed on the supporting base of the plate spring; the supporting base of the plate spring is hinged with the rear end of the vehicle frame; automatic unloading can be realized by the action of a hydraulic oil cylinder; both ends of the reinforcing cross beam of the rear bridge are fixed on the longitudinal beam of the vehicle frame; a gear box body and the half shaft are connected with U-shaped screw bolts for external application, which are connected with the reinforcing cross beam of the rear bridge. The utility model can realize load conveyance and can be used for farmland operation; the rear bridge of the tractor can not be damaged easily; the utility model is an optimum selection replacing with a small-four-wheel tractor.

Description

Double frame type load-carrying trac.

The utility model relates to a kind of double frame type load-carrying trac., is used for load transportation and farmland operation.

Existing trac. can only be used for farmland operation and traction transportation, and can not load transportation, when as the traction transportation, need articulate trailer, and unit body is long, uses inconvenience, and tractive force is little, and agriculture truck can only load transportation, can not be used for farmland operation.Chinese patent application numbers 96202160.1 discloses a kind of " multifunctional tractor ", feature is that railway carriage directly is pressed on the back axle, can be used for the farmland again with already though this trac. has realized being used for load-carrying, and tractor rear axle is stressed too big, therefore, easily cause damage.

The purpose of this utility model is to provide a kind of can be used for load transportation, can be used for farmland operation again, and not fragile tractor rear axle, a kind of double frame type load-carrying trac. easy to use.

The purpose of this utility model is achieved in that

The utility model includes wheel, deflector, operator's compartment, throttle control system, hydraulic efficiency pressure system, engagement ﹠ disengagement braking system, driving engine, vehicle frame, frame etc., and operator's compartment is positioned at the vehicle frame front end, it is characterized in that:

(1) rear end of chassis side rail is fixed on the rear-axle tube with U-bolt, and the vehicle frame front end cross beam is connected with front axle with the transverse plate spring by waving assembly, and front axle is by longitudinal tie and chassis side rail hinge joint;

(2) container places on the vehicle frame, and the container rear end is outstanding back laminated spring, and back laminated spring is fixed on the laminated spring bearing by U-bolt, laminated spring bearing and the hinge joint of chassis side rail rear end;

(3) the back axle deep beam is positioned at back axle top, and the crossbeam two ends are separately fixed on the chassis side rail on the axle tube, and in casing and semiaxis junction, about respectively hang and connect with a U-bolt and back axle deep beam;

(4) on the frame diesel engine is installed, all weld with vehicle frame at frame front end and middle part, and the rear end is connected with the change speed gear box front end by connecting panel.

The back axle deep beam can be fixed with two ends, the axle tube left and right sides.

The utility model has transferred on the axle tube weight that is pressed on the casing because what adopt is the double frame type structure, owing to used the back axle deep beam to offset to act on the moment of flexure of axle tube and casing junction, can avoid the casing damage.The utility model can be used for farmland operation, can be used for load transportation again, and easy to use.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model double frame type structure;

Fig. 3 is the utility model back axle deep beam constructional drawing;

Fig. 4 is the utility model propons structural front view;

Fig. 5 is the utility model propons left view.

The utility model consists predominantly of wheel, deflector, operator's compartment, throttle control system, hydraulic efficiency pressure system, engagement ﹠ disengagement braking system, driving engine, vehicle frame, frame etc., and operator's compartment is positioned at the front end of vehicle frame, it is characterized in that:

(1) rear end of vehicle frame 5 longerons is fixed on the rear-axle tube with U-bolt 10, and vehicle frame 5 front end cross beams 19 are connected with front axle 1 with transverse plate spring 3 by waving assembly 4, and front axle 1 is by longitudinal tie 23 and the hinge joint of vehicle frame 5 longerons;

(2) container 9 rear ends are outstanding back laminated spring 8, and back laminated spring 8 is fixed on the laminated spring bearing 14 by U-bolt 15, laminated spring bearing 14 and the hinge joint of chassis side rail rear end;

(3) back axle deep beam 7 is positioned at back axle top, and crossbeam 7 two ends are separately fixed on the chassis side rail on the axle tube 11, gearbox body 12 and semiaxis junction, about each hangs with nut with a U-bolt 18 and back axle deep beam and connects;

(4) on the frame 13 diesel engine 16 is installed, all weld with vehicle frame 5 at frame 13 front ends and middle part, and the rear end is connected with change speed gear box 12 front ends by connecting panel 7.

The back axle deep beam also can be fixed with two ends, the axle tube left and right sides.

The utility model propons adopts farmland transport trolley propons, and back axle adopts the small four-wheel tractor back axle.Trac. is connected by hydraulic oil pipe oil pump when making load transportation with hydraulic ram, and promotes the fluid control bar forward, and liter is beyond the Great Wall annotated in hydraulic ram work, promotes cardan axle, and jack-up container 9 is finished the self-unloading effect.After goods is unsnatched, move the fluid control bar backward, then container [9] utilizes deadweight and descends.When as farmland operation, take down the cardan axle on the laminated spring bearing 14, container 9 is unloaded, take away the hydraulic oil pipe that joins with hydraulic ram then, connect the bonnet oil pipe, and connect with bonnet, and will the back hang to articulate and load onto agricultural machinery and implement with lift arm, make oil pump high pressure oil act on oil cylinder bonnet in by the control maneuvering system this moment, promote piston make by push rod in the needle arm rotate, thereby drive lift arm work, agricultural machinery and implement are realized lifting action.
