Abstract
The utility model relates to a suspension lifting structure of a tractor, which is mainly composed of a hydraulic cylinder, a lifting support seat, a lifting rotary shaft, an inner lifting arm, and an outer lifting arm. The hydraulic cylinder support seat is connected with a tractor frame, the lifting support seat is connected with a gear box of a rear axle or an upper end surface on a rear gear pack, and the motion of the lifting arm is pushed by a pushing rod of the hydraulic cylinder. The structure of the utility model has the advantages of small maintenance quantity and low integral height, and is beneficial to the installation of a carriage.
Description
The utility model relates to agri-vehicle, particularly the trac. technical field.
At present, known trac. suspension lifting structure is formed an integral body by housing, fuel tank, piston, push rod, inside and outside lift arm etc., claims back axle change speed gear box bonnet.The motion of the piston in the bonnet, push rod, inside and outside lift arm is easily had problems by high pressure oil promotion, piston, the push rod part that gear type pump or notes plug pump produce, maintenance load is big, moreover, the bonnet whole height is big, be installed on back axle change speed gear box top, make whole back axle change speed gear box whole height big, be unfavorable for installing additional of compartment.
The purpose of this utility model provides a kind of suspension lifting structure of trac., has good lifting performance simultaneously, and simplified structure reduces whole height, and it is little and be beneficial to installing additional of compartment to make it maintenance load.
The purpose of this utility model is achieved in that with hydraulic actuating cylinder, lifting support, lift shaft, inside and outside lift arm forms the suspension lifting structure, the hydraulic actuating cylinder bearing is connected with bolt with vehicle frame, lifting support is connected with bolt with the upper surface of back axle change speed gear box or backteeth bag, interior lift arm and hydraulic actuating cylinder push rod flexibly connect with pin, and inside and outside lift arm motion is promoted by the hydraulic actuating cylinder push rod.
Owing to take such scheme, the utility model has good lifting performance simultaneously, simple in structure, whole height reduces, and is beneficial to installing additional of compartment, and trac. is not when carrying out farmland operation, hydraulic actuating cylinder changes the installation site, be not connected, be connected, make the compartment have elevating function with the compartment with interior lifting arm.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 the utility model front view.
Fig. 2 the utility model birds-eye view.
1 hydraulic actuating cylinder, 2 hydraulic actuating cylinder rotating shafts, 3 hydraulic actuating cylinder bearings, 4 hydraulic actuating cylinder push rods, 5 outer lift arms, 6 interior lift arms, 7 lifting supports, 8 pins, 9 lift shafts among the figure
In Fig. 1, hydraulic actuating cylinder bearing (3) is connected with bolt with vehicle frame, hydraulic actuating cylinder rotating shaft (2) flexibly connects for axle sleeve with hydraulic actuating cylinder bearing (3), lifting support (7) is wrapped end face with bolt with back axle change speed gear box or backteeth and is captiveed joint, lift shaft (9) flexibly connects for axle sleeve with lifting support (7), outer lift arm (5), interior lift arm (6) are captiveed joint with key with lift shaft (9), hydraulic actuating cylinder push rod (4) flexibly connects with pin with interior lift arm (6), when hydraulic actuating cylinder push rod (4) moves, lift arm (6) motion in driving.When interior lift arm (6) when not needing to move, hydraulic actuating cylinder push rod (4) is not connected with interior lift arm (6), and hydraulic actuating cylinder push rod and compartment flexibly connect, and becomes the power of compartment self-unloading.
Claims (1)
