Abstract
The utility model relates to a steering transitional rocker arm bracket assembly which comprises a rocker arm fixing bracket, a rock arm shaft, a rocker arm, a lining and a fixing nut, wherein the rocker arm comprises a sleeve and a rocker arm body; a through hole is formed in the rocker arm body; one end of the sleeve passes into the through hole; the lining is pressed into the sleeve; the rocker arm fixing bracket and the rocker arm shaft adopt an integrated structure; a thread is formed at the other end of the rocker arm shaft; the rocker arm shaft penetrates through the rocker arm and the lining in sequence and is fixed through the fixing nut. The steering transitional rocker arm bracket assembly adopts an integrated structure, namely the rocker arm shaft and the rocker arm fixing bracket are forged to form an integrated piece, and thus shaking, which is caused by clearance fit of parts, of the rocker arm shaft is avoided.
Description
Technical field
The utility model belongs to automobile steering device field, specifically refers to a kind of transition rocker arm support assembly.
Background technology
The structure of at present two propons transition rocker arm support assemblies is as shown in Figure 1; rocking arm fixed support 1 is casting; material QT450; be provided with six bolts hole; rocker shaft 2 is Forging Parts, material 40Cr, and two pads 3 lay respectively at the two ends of Rocker arm 4; lining 5 is pressed in rocking arm hole, and cushion block 6 is between slotted nut 7 and pad.The feature of this structure is that rocking arm fixed support is ironcasting, and rocker shaft is separation type.
Rocking arm fixed support is foundry goods, inevitably can produce the defects such as shrinkage cavity and porosity, poor reliability.And foundry goods is heavier, rocking arm fixed support and rocker shaft weight are large.Rocking arm fixed support and rocker shaft are free-running fit, and in use procedure, rocker shaft inevitably can produce and rock, and cause the faults such as tire undue wear, affect steering swivel system overall performance.Rocking arm fixed support and rocking arm need assembling, many one assembling procedures, and rocking arm fixed support needs 6 bolts to fix, and installs loaded down with trivial detailsly, and it is large that shared space is installed on car load.
Utility model content
The purpose of this utility model is by existing transitional rocker bracket assembly is improved, and overcomes rocking arm fixed support and rocker shaft and has free-running fit, produces and rocks problem, and can reduce assembling procedure.
The utility model is achieved through the following technical solutions:
A transition rocker arm support assembly, includes rocking arm fixed support, rocker shaft, rocking arm, lining and captive nut; Described rocking arm includes sleeve pipe and rocking arm body; On described rocking arm body, be provided with through hole, on described rocking arm body with described sleeve pipe;
Described lining is pressed in described sleeve pipe;
Described rocking arm fixed support and described rocker shaft are structure as a whole, and the other end of described rocker shaft is provided with screw thread; Described rocker shaft passes rocking arm and lining successively, and fixes by captive nut.
Described rocking arm body and described sleeve pipe are structure as a whole.
An end face of described sleeve pipe and a surface of described rocking arm body are in same plane.
The two ends of described rocking arm are respectively provided with a pad; Described rocker shaft is through described pad.
Between described captive nut and described sleeve pipe, be also provided with cushion block; Described rocker shaft is through described cushion block.
On described rocking arm fixed support, be provided with four bolts hole.
Described captive nut is slotted nut.
The beneficial effects of the utility model are:
The structure of the technical program is one-piece construction, and rocker shaft and rocking arm fixed support are forged to integral piece, avoids parts free-running fit and the rocker shaft that causes rocks.
Rocking arm fixed support and rocking arm forge integral structure, can reduce assembling procedure one, and rocking arm fixed support are fixed by 4 bolts.
Accompanying drawing explanation
Fig. 1 is the transition rocker arm support assembly decomposition texture schematic diagram of existing technology;
Fig. 2 is the transition rocker arm support assembly decomposition texture schematic diagram of an embodiment of the utility model.
The specific embodiment
Describe by the following examples the technical solution of the utility model in detail, following embodiment is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
As shown in Figure 2, a kind of transition rocker arm support assembly, includes rocking arm fixed support 101, rocker shaft 102, rocking arm, lining 107 and captive nut 109; In the application's technical scheme, rocking arm fixed support 101 and described rocker shaft 102 are structure as a whole, and by solid forging, process, and avoid parts free-running fit and the rocker shaft that causes rocks.Adopt 40Cr material, after modifier treatment, mechanical characteristics is better than spheroidal graphite iron greatly, and the interiors of products after forging is organized tightr, there is no defect of fabrication, good reliability.
40Cr forging mechanical property is better than nodular iron casting, and its intensity, rigidity significantly promote before comparing, and can realize integral body and fall heavily in the application, falls and weighs 37%.
Rocking arm includes sleeve pipe 105 and rocking arm body 106; On described rocking arm body 106, be provided with through hole, one end of described sleeve pipe 105 penetrates described through hole; On rocking arm body 106, with sleeve pipe 105, in the present embodiment, rocking arm body and sleeve pipe are structure as a whole, and end face of sleeve pipe and a surface of rocking arm body are in same plane, and lining 107 is pressed in described sleeve pipe 105.
The other end of described rocker shaft is provided with screw thread, and is provided with dowel hole radially in the threaded part of tool, for passing locating dowel pin.Rocker shaft 102 is successively through pad 104, rocking arm and lining, pad and cushion block 108, and it is fixing to pass through captive nut 109.Captive nut is in this application slotted nut, refers to that one end of captive nut is provided with groove, the nut that the other end is plane, and in this application, the end face that slotted nut has plane contacts with cushion block, and the reeded one end of tool is outside.
On rocking arm fixed support, be provided with four bolts hole 103, than the rocking arm fixed support in the transition rocker arm support assembly of existing use, reduced by two bolts hole, can improve assembling speed.
Although illustrated and described embodiment of the present utility model; for the ordinary skill in the art; be appreciated that in the situation that not departing from principle of the present utility model and spirit; can carry out multiple variation, modification, replacement and modification to these embodiment, these also should be considered as protection domain of the present utility model.Scope of the present utility model is by claims and be equal to and limit.
