Abstract
The utility model discloses a steering gearbox assembly with a secondary limiting structure, belonging to the technical field of an accessory of an automobile steering device. The technical essentials are as follows: the steering gearbox assembly with the secondary limiting structure comprises a steering gearbox shell, a spherical head pull rod and a rack, wherein the spherical head pull rod and the rack are arranged in the steering gearbox shell; the spherical head pull rod and the rack are connected with each other; a metal limiting block is arranged inside the steering gearbox shell on the periphery of the rack; a rubber baffle block is arranged on the periphery of the end part of one end of the rack, which is connected with the spherical head pull rod; and an elastic washer is arranged on the periphery of the rack at the outer side of the rubber baffle block. The utility model aims to provide the steering gearbox assembly with the secondary limiting structure, which has the advantages of reasonable structure, good buffering effect and higher safety; and the steering gearbox assembly with the secondary limiting structure can be used for an automobile steering device.
Description
Technical field
The utility model relates to a kind of automobile steering device assembly, more particularly, relates in particular to a kind of direction thermomechanical components that has the secondary position limiting structure.
Background technology
In existing steering arrangement, ball-head tension rod is assembled on the tooth bar, and the limit method of its stroke can overlap a rubber block usually on tooth bar, and profit purpose in such a way is to produce collision in order to prevent ball-head tension rod and metal limiting stopper direct contact.But because deflector long-term use work, and racing is excessive when turning to left and right sides maximum angle to exerting oneself, and ball-head tension rod and metal limiting stopper produce moment and fiercely impact, thereby make the rubber block compressive deformation, cause the safety hazard increase.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of rational in infrastructure, buffering effect is good and safety is higher direction thermomechanical components that has the secondary position limiting structure is provided.
The technical scheme of the utility model is achieved in that a kind of direction thermomechanical components that has the secondary position limiting structure, comprises the direction engine housing, is arranged on ball-head tension rod and tooth bar in the direction engine housing, and ball-head tension rod and tooth bar interconnect; In the direction engine housing of tooth bar periphery, be provided with the metal limiting stopper, be provided with rubber block, the flexible packing ring of tooth bar outer periphery in the wherein said rubber block outside in the periphery, an end end that tooth bar is connected with ball-head tension rod.
In the above-mentioned direction thermomechanical components that has the secondary position limiting structure, the external diameter of described spring washer is greater than the external diameter of rubber block.
After the utility model adopted said structure, spring washer was enclosed within tooth bar foremost, is positioned in the middle of metal limiting stopper and the rubber block; Even if because the spring washer stretch ratio is high, impact absorbency and absorption of vibrations property are good, so deflector long-term work use; Racing is when exerting oneself excessive or turning to the dead angle; Spring washer carries out secondary and relaxes impact after rubber block, eliminate vibration, absorbs bigger crash energy.The utility model delicate structure can play the spacing effect of secondary, and is safe and reliable, and the protection product prolongs product life.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation at ball-head tension rod and metal limiting stopper position under the utility model initial condition;
Fig. 3 is the structural representation that the utility model carries out once ball-head tension rod and metal limiting stopper position when spacing;
Fig. 4 is the structural representation that the utility model carries out secondary ball-head tension rod and metal limiting stopper position when spacing.
Among the figure: direction engine housing 1, ball-head tension rod 2, tooth bar 3, metal limiting stopper 4, rubber block 5, spring washer 6.
The specific embodiment
Consult illustrated in figures 1 and 2ly, a kind of direction thermomechanical components that has the secondary position limiting structure of the utility model comprises direction engine housing 1, is arranged on ball-head tension rod 2 and tooth bar 3 in the direction engine housing 1, and ball-head tension rod 2 interconnects with tooth bar 3; In the direction engine housing 1 of tooth bar 3 peripheries, be provided with metal limiting stopper 4, be provided with rubber block 5, it is characterized in that the flexible packing ring 6 of tooth bar 3 outer periphery in described rubber block 5 outsides in the periphery, an end end that tooth bar 3 is connected with ball-head tension rod 2.Further, for the validity that guarantees to cushion, the external diameter of the utility model spring washer 6 is greater than the external diameter of rubber block 5.
Consult Fig. 3 and shown in Figure 4, when the automobile racing when exerting oneself excessive or turning to the dead angle, at first rubber block 5 contacts with metal limiting stopper 4 and carries out first time buffering; If when impulse force was big, spring washer 6 contacted with metal limiting stopper 4 again, thereby realize secondary buffer; Eliminate vibration; Absorb bigger crash energy, reach the purpose of protection deflector parts, prolong the service life of product.
