Abstract
The utility model relates to a steering mechanism assembly in a car and in particular relates to a draw bar joint assembly. The draw bar joint assembly comprises a ball seat, a high polymer material lining and a ball pin draw rod, wherein the ball seat is provided with an inner cavity; the high polymer material lining is arranged in the inner cavity; the ball pin draw bar is provided with a ball head in the lining; and a plurality of compensating slots are arranged on the outer surface, contacting with the bottom of the inner cavity, of the lining. The compensating slots are directly arranged on the lining, so that the deformable amount of the lining is increased; the elastic force generated in the self-compression process of the lining is used for compensating, so that the compensating elastic force is large. Moreover, a rubber compensating cushion is omitted, so that the assembling is easy, and losing and moving are avoided.
Description
Technical field
The utility model relates to the steering mechanism assembly in a kind of automobile, relates in particular to a kind of rod head assembly.
Background technique
The rod head assembly is the part of automotive steering structure, and it is used to drive wheel steering.Existing rod head assembly comprises ball seat with inner chamber body, be arranged on macromolecular material lining in the inner chamber body, have the ball pin pull bar that is arranged at the bulb in the lining.In automobilism, the rod head assembly is stressed bigger, the gap appears between ball pin pull bar and the lining easily, reduce working life, in order to improve working life, the rod head assembly that has is provided with rubber compensation pad between the bottom of lining and inner chamber body, the resiliently deformable by the compensation pad compensate that lining compresses and bulb between the gap.But this compensation has a snack that to repay elastic force less, and is difficult for assembling, occurs loose shift easily, influences using effect.Original rod head assembly is realized the circulation of commutator internal gas by offering vent anyhow in the ball seat threaded interior, and this kind ventilation form easily reduces screw strength.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of rod head assembly, and compensation elastic force is big, and assembling loose shift can not occur easily.
For achieving the above object, rod head assembly of the present utility model, comprise ball seat with inner chamber body, be arranged on macromolecular material lining in the inner chamber body, have the ball pin pull bar that is arranged at the bulb in the lining, the outer surface that described lining contacts bottom inner chamber body is provided with a plurality of compensating tanks.
As to qualification of the present utility model, the bottom of described lining has center hole, and described compensating tank distributes along the center hole divergent shape.
As to qualification of the present utility model, on ball seat, be provided with vent, on the ball seat screw thread, be provided with the vertical fluting that links to each other with vent;
As to qualification of the present utility model, be provided with the lubrication groove of many storage lubricant mediums at the inwall of lining.
Adopt technique scheme, its beneficial effect is as follows: by compensating tank directly is set on lining, increased the deformable amount of lining, the elastic force that produces when compressing by lining self compensates, and compensation elastic force is big, and has cancelled rubber compensation pad, assembling has been avoided loose shift easily; Compensating tank distributes along the center hole divergent shape, and resiliently deformable is effective, and is easy to make; Vent is set on ball seat, this vent is connected with the through hole of commutator gear bar internal run-through with vertical fluting, two rod head assemblies of left and right vehicle wheel and commutator realize gas circulation by interior accessibke porosity, this kind vent can effective ventilation, can make screw strength reduction degree reduce to minimum again.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is done further to describe in detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic representation of the lining of present embodiment;
Fig. 3 is that the A of lining among Fig. 2 is to view.
Among the figure: 1-ball seat, 2-lining, 3-ball pin pull bar, 4-compensating tank, 5-lubrication groove, 6-vent, 7-center hole, 8-bulb.
Embodiment
As shown in Figure 1 to Figure 3, the rod head assembly of present embodiment, comprise ball seat 1 with inner chamber body, be arranged on macromolecular material lining 2 in the inner chamber body, have the ball pin pull bar 3 that is arranged at the bulb 8 in the lining 2, the outer surface that lining 2 is used for contacting with the inner chamber body bottom is provided with a plurality of compensating tanks 4.Be provided with center hole 7 in the bottom of lining 2, these compensating tanks 4 are divergent shape along center hole 7 and distribute.When work, 8 pairs of linings of the bulb of ball pin pull bar 32 produce squeezing action, because the existence of compensating tank 4, the bottom of lining 2 has had the certain deformation space, therefore lining 2 can produce bigger metamorphosis, thereby produce bigger compensation elastic force, when bulb 8 does not push lining 2, lining 2 can restore to the original state under the effect of this compensation elastic force, and therefore, the durability of this lining 2 is better, working life is longer, and cancelled the rubber compensation pad in the existing structure, assembling has been avoided loose shift easily.
On ball seat 1, be provided with vent 6, the effect of vent 6 is, this assembly is packed into after the commutator, this vent is connected with the through hole of commutator gear bar internal run-through, two rod head assemblies of left and right vehicle wheel and commutator realize gas circulation by interior accessibke porosity, this kind vent can effective ventilation, can make screw strength reduction degree reduce to minimum again.Be provided with the lubrication groove 5 of many storage lubricant mediums on the inwall of lining 2, these lubrication grooves 5 adopt horizontal and vertical staggered setting type, can provide permanent lubrication effect for bulb 8.
