Description
Technical field
The utility model relates to spring after poppet after a kind of light truck, belongs to automobile technical field.
Background technology
The rear suspension of the light truck of little tonnage adopts the structure of major-minor steel spring, and in order to meet understeering, rear suspension adopts low early and high after layout, and rear suspension of the prior art mostly adopts hanger and rear spring after poppet arrangement form (as shown in Figure 4); The light truck of present little tonnage adopts lower vehicle frame, rear suspension just is difficult to rational deployment on limited space, meet if the performance perameter of car load and the arrangement parameter of suspension, still adopt the arrangement combinations of forging hanger and rear spring after poppet, plate spring front bracket and leaf spring connecting bore will widen greatly to the distance of vehicle frame lower aerofoil, the suspension elevated height that causes rear suspension, autocentre improves, bad stability.
Summary of the invention
Technical problem to be solved in the utility model is the problem existed for prior art, provides a kind of and is convenient to the rear spring after poppet that low vehicle frame is arranged, and support is carried out to structure optimization, and expendable weight, reduce costs.
For solving this technical matters, the utility model provides a kind of rear spring after poppet assembly for light truck, comprise casting frame body, the non-maintaining composite bush of rubber and hanger inner and outer plates assembly, the excessive structure of the whole L-shaped Rouno Cormer Pregrinding Wheel of described casting frame body, be provided with horizontal connecting surface and vertical joint face on the top of casting frame body, this horizontal connecting surface is equipped with connecting bore with on vertical joint face, and the casting frame body is used bolt to be connected on vehicle frame by this horizontal connecting surface and vertical joint face; Be provided with the hanger connecting bore in the lower end of casting frame body, in the hanger connecting bore, by transition fit, be pressed into the non-maintaining composite bush of rubber; Hanger inner and outer plates assembly one end is connected with the casting frame body by the hanger connecting bore, and the other end is connected with steel plate spring assembly by the leaf spring grasswort.
Described casting frame body is provided with lightening grooves.
Described casting frame body is provided with at least two place's reinforced ribs, and described each reinforced rib is in same plane.
The whole QT450 casting that adopts of described casting frame body.
Described casting frame body is the left-right symmetric structure.
Beneficial effect: the utility model compared with prior art, setting by L shaped casting frame body, met the suspension design arrangement requirement that after the light truck, vehicle frame is low, setting by lightening grooves and reinforced rib, not only weight alleviates greatly, and can ensure requirement of strength, reduced comprehensive productive costs; Relatively original regular grease up of needs that is connected with the leaf spring pin by lubrication adapter, now the support by the design adopts non-maintaining structure can effectively promote the traveling comfort of car load.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is casting frame body construction schematic diagram of the present utility model;
The A that Fig. 3 is casting frame body of the present utility model is to structural representation;
The structural representation that Fig. 4 is prior art.
Wherein: 1 casting frame body, the non-maintaining composite bush of 2 rubber, 3 hanger inner and outer plates assemblies, 4 steel plate spring assemblies, 5 auxiliary spring supports, 6 vehicle frames, 7 connecting bores, 8 hanger connecting bores, 9 lightening grooves, 10 reinforced ribs.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, following explanation is only exemplary, does not limit protection domain of the present utility model.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises casting frame body 1, the non-maintaining composite bush 2 of rubber and hanger inner and outer plates assembly 3.
The excessive structure of the whole L-shaped Rouno Cormer Pregrinding Wheel of described casting frame body 1, be provided with horizontal connecting surface and vertical joint face on the top of casting frame body 1, this horizontal connecting surface is equipped with connecting bore 7 with on vertical joint face, casting frame body 1 is used bolt to be connected on vehicle frame 6 by this horizontal connecting surface and vertical joint face, be provided with hanger connecting bore 8 in the lower end of casting frame body 1, in hanger connecting bore 8, by transition fit, be pressed into the non-maintaining composite bush 2 of rubber.
Hanger inner and outer plates assembly 3 one ends are connected with casting frame body 1 by hanger connecting bore 8, the other end is connected with steel plate spring assembly 4 by the leaf spring grasswort, when leaf spring deforms, the interlock hanger moves in a circle, by the torsional deflection of the non-maintaining composite bush 2 of rubber, avoid intermetallic dry friction to occur, and there is noise reduction, vibration damping, the effect of buffering.
Described casting frame body 1 is provided with lightening grooves 9.
The utility model utilizes the principle of the few face of many muscle, and many places are provided with reinforced rib 10, and guarantees that as far as possible front and back reinforced rib 10 is in same plane.
The whole QT450 casting that adopts of described casting frame body 1.
Described casting frame body 1 is the left-right symmetric structure.
Also be provided with auxiliary spring support 5 on described vehicle frame 6.
When arranging rear suspension, rear spring after poppet assembly is arranged on vehicle frame 6 and will meets: under the fully loaded state of applanation of steel plate spring assembly 4, hanger inner and outer plates assembly 3 recedes, and makes so stressed its structure of effectively utilizing of rear spring after poppet assembly.
The utility model compared to existing technology rear spring after poppet structurally be optimized, setting by L shaped casting frame body, met the suspension design arrangement requirement that after the light truck, vehicle frame is low, setting by lightening grooves and reinforced rib, weight is being fallen on heavy basis with original support contrast, and can ensure requirement of strength, reduced comprehensive productive costs; Realized the design of non-maintaining structure, relatively original regular grease up of needs that is connected with the leaf spring pin by lubrication adapter, now the support by the design adopts non-maintaining structure can effectively promote the traveling comfort of car load, rear suspension is in the layout of narrow vehicle frame, can effectively reduce the suspension height, eliminate the interference of hanger inner and outer plates assembly 3 on the gos to vehicle frame 6 and 1 generation of casting frame body.
The above-mentioned embodiment of the utility model, just casehistory, be not only, all in the utility model scope or the change be equal in scope of the present utility model all by the utility model, surrounded.
