Description
Technical field
The utility model relates to automobile component field, is specifically related to a kind of low speed rotation and radial direction can bear the vertical middle pitman shaft band Rocker arm assembly of automobile of greater impact.
Background technology
Along with the development of automotive technology, the automobile of multi-axle steering is more and more general.The multiple-axle vehicle of follow-up steering need pitman arm around the swing of steering intermediate shaft usually to transmit follow-up steering action.Simultaneously, along with independent suspension is more applied to heavy motor vehicle, the heavy motor vehicle steering swivel system of independent suspension, a kind of vertical middle pitman arm axle construction of usual needs realizes the swing of pitman arm, but because moment of torsion suffered on pitman arm is larger, the problems such as excessive clearance and then generation are rocked often to cause tween drive shaft to occur, minimizing in service life, cause automobile inspection frequency higher.
Utility model content
The utility model aims to provide a kind of compact conformation and can bear the vertical middle pitman shaft band Rocker arm assembly of automobile of greater impact power.
To achieve these goals, the vertical middle pitman shaft band Rocker arm assembly of automobile described in the utility model, comprise tween drive shaft, a pair tapered roller bearing, housing, pitman arm, end cap, caging bolt, nut, O RunddichtringO, described a pair tapered roller bearing is installed on housing and arranges with dos-à-dos form, the tapered roller bearing internal ring and the tween drive shaft that are assemblied in tween drive shaft end adopt interference fit, be assemblied in tapered roller bearing internal ring in the middle part of tween drive shaft and tween drive shaft adopts free-running fit, described tween drive shaft and pitman arm pass through spline joint, in the below of pitman arm, fastener is set.End cap is arranged on housing upper, housing is provided with caging bolt and nut, for limiting pitman arm position, wherein, described pitman arm arranges a flange, and the hole of this flange and pitman arm being installed spline is coaxial, and the inner ring of flange upper surface and described tapered roller bearing abuts against, adopt free-running fit between flange outer rim and housing, and O RunddichtringO is set in flange outer rim.
Preferably, the outer ring of described a pair tapered roller bearing is integrated on housing and forms a part.
Preferably, a flange nut is set, for regulating bearing space and fastening pitman arm in the below of described pitman arm.
Further, offer groove in the radial direction of described tween drive shaft, after fastening pitman arm, the flange of flange nut is snapped in groove, locking effect can be played.
The vertical middle pitman shaft band Rocker arm assembly of automobile described in the utility model, by arranging flanged structure on rocking arm, both served positioning action, compacter with seasonal integral structure, reduced rocking of tween drive shaft, strengthened impact resistance.The outer ring of tapered roller bearing is integrated on housing and by a flange nut and realizes the adjustment of bearing space and the fastening of pitman arm, compactedness and the impact resistance of structure can be strengthened further, significant for practical application.
Accompanying drawing explanation
Fig. 1 is the External view of the vertical middle pitman shaft band Rocker arm assembly of automobile of the present utility model;
Fig. 2 is the cross-sectional view of the vertical middle pitman shaft band Rocker arm assembly of automobile of the present utility model;
Fig. 3 is the decomposition texture schematic diagram of the vertical middle pitman shaft band Rocker arm assembly of automobile of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Composition graphs 1 ~ Fig. 3, the vertical middle pitman shaft band Rocker arm assembly of automobile described in the utility model, comprise tween drive shaft 2, a pair tapered roller bearing 3, 3 ', housing 4, pitman arm 7, end cap 1, caging bolt 6, nut 5 and O RunddichtringO 10, a pair tapered roller bearing 3, 3 ' is installed on housing and arranges with dos-à-dos form, tween drive shaft 2 is successively through tapered roller bearing 3, 3 ', the tapered roller bearing 3 being assemblied in tween drive shaft 2 end adopts interference fit with tween drive shaft 2, the tapered roller bearing 3 ' be assemblied in the middle part of tween drive shaft 2 adopts free-running fit with tween drive shaft 2, tween drive shaft 2 and pitman arm 7 pass through spline joint, in the below of pitman arm 7, fastener is set, the present embodiment is arrange a flange nut 9 in the below of pitman arm 7, as shown in Figure 2.End cap 1 is arranged on the top of housing 4, housing 4 is provided with caging bolt 6 and nut 5, for limiting the position of pitman arm 7.The problem of rocking is produced because bearing space is excessive in order to what solve that tween drive shaft 2 easily occurs, pitman arm 7 is provided with a flange 11, the hole of flange 11 and pitman arm 7 being installed spline is coaxial, upper surface and the tapered roller bearing 3 ' inner ring of flange 11 abut against, and adopt free-running fit and mounting O-shaped seal ring 10 between the outer rim of flange 11 and housing 4.Flange 11 abuts against with the inner ring of tapered roller bearing 3 ' and serves positioning action, simultaneously owing to making integral structure compacter with coordinating of housing, contributes to reducing rocking of tween drive shaft, strengthens impact resistance.
In order to make integral structure compacter, strengthen impact resistance further, by tapered roller bearing 3, outer ring and the housing 4 of 3 ' are integrally formed.
Preferably, arrange a flange nut 9, install pad 8 between flange nut 9 and pitman arm 7 in the below of pitman arm 7, the adjustment of bearing space and the fastening of pitman arm 7 can be realized by this flange nut 9.Offer groove in the radial direction of tween drive shaft 2, when after fastening pitman arm 7, the flange of flange nut 9 being snapped in described groove, the flange that the present embodiment have employed just flange nut 9 digs into the mode of described groove, serves locking effect.
The fastener arranged below pitman arm 7 can also be self lock nut, double nuts etc.
