Abstract
The utility model provides a balance suspension device for automobile crane, which is composed of steel plate springs, weigh beams, vehicle axles, distance rods and a support, main structure is composed of four sets of same steel plate springs connecting by three sets of same weigh beams, the weigh beams are mounted on the middle support, the steel plate springs are fixed respectively on the four vehicle axles with equivalent wheelbase; two distance rods respectively hinge on the two ends of the vehicle axle on each vehicle axle, the other end of the distance rod hinges with the middle support. The utility model has advantages that, the load of any one vehicle axle is equivalent under stationary state; when the load of any one vehicle axle changes, which is transferred to the other three sets of steel plate springs under running state, untill satisfying new equilibrium state, thereby realizing the load of each vehicle axle completely consistent.
Description
Technical field
The utility model relates to a kind of car hosit draft hitch, particularly multi-axle automobile hoisting crane equalizing-suspension device.
Background technology
At present, multi-axle automobile hoisting crane draft hitch often adopts the steel spring suspension as supporting and shock attenuation unit, but most of balance suspensions are one group on two bridges, when the car hosit number of axle reaches six, design one group on two bridges routinely and be total to three groups of balance suspensions of palpus, and statically indeterminate problem appears in this structure easily, causes every group of axle load inhomogeneous.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of car hosit distribution of axle load uniform equalizing-suspension device
The purpose of this utility model is achieved in that described equalizing-suspension device is made of steel spring, equalizing bar, vehicle bridge, propelling rod and bearing, bearing comprises preceding bearing, middle bearing and rear support, be arranged in the underframe both sides and be fixed on the underframe, its structure is: connected by three groups of identical equalizing bars by four groups of identical steel springs, steel spring is separately fixed at the continuous supporting of four rear supports and is set to the slide plate supporting structure.
Steel spring two ends slide plate supporting-point equates to bridge centre distance.Equalizing bar two ends slide plate supporting-point equates to equalizing bar rotating shaft center distance.On the vehicle bridge that wheelbase equates, equalizing bar is installed in respectively on the center shaft of bearing in three groups, has two propelling rods to be hinged on the vehicle bridge two ends respectively on each root vehicle bridge, and the other end of propelling rod and middle bearing are hinged.
The two-side supporting that steel spring links to each other with equalizing bar and with preceding,
Steel spring is fixed on the vehicle bridge by spring bearer plate and saddle clamp.
The usefulness of said structure is: supporting-point is stressed before and after the steel spring equates, equalizing bar two-side supporting point is stressed to be equated, and because the steel spring on each root bridge is all identical with the equalizing bar between per two bridges, so the load of under static state any bridge equates, under motoring condition, when the load variations on any bridge, all will be delivered on other three groups of steel springs by steel spring and equalizing bar, up to satisfying new state of equilibrium, thereby the load of realizing every bridge is in full accord.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is four bridge steel spring equalizing-suspension device Facad structure scheme drawings.
Among the figure: 1, preceding bearing, 2, steel spring, 3, saddle clamp, 4, spring bearer plate, 5,9,11,12, vehicle bridge, 6, propelling rod, 7,10, middle bearing, 8, equalizing bar, 13, rear support, 14, the slide plate supporting-point, 15, equalizing bar axle center, 16, axle center.
The specific embodiment
As shown in Figure 1, linked to each other by four groups of identical steel spring 2 green phases equalizing bar 8 together, the center of every group of steel spring 2 is separately fixed on the equal vehicle bridge 5,9,11,12 of four wheelbases.The two-side supporting that steel spring 2 links to each other with equalizing bar 8 is set to the slide plate supporting structure, steel spring 2 is a slide plate supporting-point 14 with the contact point at equalizing bar 8 two ends, 15 distances equate the slide plate supporting-point 14 at equalizing bar 8 two ends to equalizing bar axle center, and the slide plate supporting-point 14 at steel spring 2 two ends equates to the distance of axle center 16.Preceding bearing 1, rear support 13, middle bearing 7,10 are arranged in the underframe both sides and are fixed on the underframe, equalizing bar 8 is installed on middle bearing 7,10, and guarantee that equalizing bar 8 can rotate smoothly in middle bearing 7,10.Four groups of steel springs 2 are installed in front and back bearing 1,13 and the equalizing bar 8, and every group of steel spring 2 is fixed together by spring bearer plate 4 and saddle clamp 3 with four vehicle bridge 5,9,11,12 respectively.The all hinged propelling rod 6 in the two ends of vehicle bridge 5,9,11,12 is during the other end of propelling rod 6 is hinged on respectively on the bearing 7,10.
Principle of work of the present utility model is: by three groups of equalizing bars and four groups of propelling rods four groups of steel springs and vehicle bridge are coupled together, steel spring is only born vertical loads, and propulsive effort and braking force are born by propelling rod.Under static state, the load of any bridge equates.Under motoring condition, when the load variations on any bridge, all will be delivered on other three groups of steel springs by steel spring and equalizing bar, up to satisfying new state of equilibrium, thereby the load of realizing every bridge is in full accord.
Claims (4)
