Abstract
The utility model relates to an oil cylinder assembly, and a hydraulic lifting gear for tyres is composed of a rear steel plate spring, a rear suspension lifting lug, a rear suspension swinging arm. The utility model is mainly used for lifting the tyres of car swing arm type follow-up bridge. Because the mechanical levers, such as original cross beams, force arms, shafts, cranks, etc. are canceled, the utility model has the advantages of less parts, easy installation, large use force, high safety, low failure rate, simple operation, low cost, etc.
Description
The utility model relates to the tire lifting device on a kind of automobile swing arm type follow-up bridge
Autotruck (as EQ144) with swing arm type flower wheel, reduce the automobile turning radius when making zero load, improve the maneuvering performance of automobile, increase the adhesive weight of axle drive shaft, improve the empty wagons travelling comfort and can improve unloaded ice and snow, the ability of muddy road surface passed through of automobile; Air-powered lifting device (east wind EQ144 type autotruck description of operation) once was equipped with in wear on tyres that transverse force causes when reducing automobile turning and the oil consumption of reduction empty wagons, and was unsettled when making flower wheel unloaded, landed during heavy duty.But cylinder volume and heavy, easily gas leakage again was so occurred hydraulic lifting device (patent No. 160216601.8) afterwards again.Yet,, except that cylinder (oil cylinder), a cover mechanical lever such as the crossbeam of supporting cylinder (oil cylinder) and the arm of force, rotating shaft, bearing seat, crank, roller is arranged all no matter be air-powered lifting device or hydraulic lifting device.Therefore parts are more, and difficulty is installed, and fault is also more relatively.
The purpose of this utility model is exactly more at above-mentioned parts, and difficulty is installed, and the problem that fault is more relatively, and adopt direct acting type tyre hydraulic lifting device reaches the function that tire on the swing arm type follow-up bridge lands when unsettled and heavily loaded when unloaded.
Concrete solution of the present utility model is: the tyre hydraulic lifting device, form by the hydraulic cylinder assembly (I) on the big fine strain of millet that is installed on the vehicle right and left steel spring (II), rear suspension hanger (III), swing arm (IV), swing arm (IV) end is connected with servo-actuated tire (V), the other end is connected with rear suspension hanger (III), and the other end of rear suspension hanger (III) is connected with steel spring (II).
With eight screws, nut and spring coil packing ring, on the big fine strain of millet above the vehicle right and left rear leaf spring, respectively adorn a hydraulic cylinder assembly.The piston rod head that constitutes by the cylinder assembly is equipped with a bearing pin, roller is housed on the bearing pin, sliding sleeve, packing ring and spring cotter, the other end of piston rod and piston assembling are blocked it with elastic spring, piston and piston rod all are contained in the cylinder barrel, the cylinder barrel head blocks guide pin bushing with elastic spring on the cylinder barrel with guide pin bushing supporting piston bar, and dust ring is housed on the guide pin bushing, do sealing, the other end of cylinder barrel and the welding of cylinder seat of piston, guide pin bushing and piston rod and piston, guide pin bushing and cylinder barrel with 6 O RunddichtringOs.Spring, nonreturn valve core, unidirectional valve seat, O RunddichtringO and the bidirectional hydraulic lock that plunger is formed are housed in the cylinder seat by two groups of plug screws.Cylinder barrel is contained in the mesopore of oil cylinder seat, and with elastic spring it is blocked, and the bearing pin head of piston rod head dress is that T type structure and sliding sleeve are contained in the T type guide groove of oil cylinder seat together.The installation site of hydraulic cylinder assembly makes piston rod face toward rear leaf spring, and roller was depressed rear leaf spring when piston rod stretched out.Promote the rear suspension hanger, make the servo-actuated tire on the swing arm type follow-up bridge unsettled, roller broke away from rear leaf spring when piston rod was return, and the servo-actuated tire of swing arm type follow-up bridge recovers to land.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a tyre hydraulic lifting device constructional drawing:
Among Fig. 1: (I)---hydraulic cylinder assembly, (II)---rear leaf spring, (III)---the rear suspension hanger, (IV)---swing arm, (V)---the servo-actuated tire, (1)---the liquid wheel, (2)---packing ring, (3)---bearing pin, (4)---sliding sleeve, (5)---spring cotter, (6)---oil cylinder seat, (7)---piston rod, (8)---dust ring, (9)---guide pin bushing, (10)---piston, (11)---elastic spring, (12)---cylinder barrel, (13)---plug screw, (14), (24), (25), (26), (27), (28)---the O RunddichtringO, (15)---spring, (16)---nonreturn valve core, (17)---unidirectional valve seat, (18)---plunger, (19)---unidirectional valve seat, (20)---the cylinder seat, (21)---nonreturn valve core, (22)---spring, (23)---plug screw, (29), (30)---elastic spring, (31)---screw, (32)---spring washer, (33)---nut.The oil inlet and outlet of A, B---oil cylinder.
Outstanding effect of the present utility model: the original crossbeam of hydraulic lifter for tyre cancellation, the arm of force, The mechanical lever such as rotating shaft, crank, parts are less, installation is easy, active force is big, safe and reliable, Fault is less, simple to operate, cost is cheap.
Embodiment: with reference to Fig. 1, the tyre hydraulic lifting device is by the hydraulic cylinder assembly (I) on the big fine strain of millet that is installed on vehicle right and left rear leaf spring (I I) top, and rear suspension hanger (III), swing arm (IV) are formed, and servo-actuated tire (V) is installed on swing arm (IV) end.Swing arm (IV) other end is connected with rear suspension hanger (III), and the other end of rear suspension hanger (III) is connected with steel spring (II).
