The perambulator foresteerage gear
Technical field
The utility model relates to the virgin perambulator technical field of baby, specifically is a kind of steering hardware of perambulator front-wheel.
Background technology
At present, living standard at people constantly promotes, scientific and technological level is constantly brought forth new ideas, most families have only a child, father and mother all constantly satisfy child's requirement, this has just promoted the development of toy market, and the perambulator product is day by day ripe simultaneously, and people are also increasing to the demand of perambulator product.Prior art perambulator foresteerage gear assembling mode be the vehicle body of putting upside down earlier, the assembly of steering hardware before the perambulator is assembled at the bottom of car, after the vehicle body that overturns again turn over to just putting state, screw the assembling that screw is finished steering hardware from the car face again.Traditional steering hardware is unfavorable for erecting work, therefore, needs further to improve.
The utility model content
The purpose of this utility model is to overcome above-mentioned technical obstacle, and a kind of perambulator foresteerage gear that is easy to assemble is provided.
The utility model is achieved in that a kind of perambulator foresteerage gear, by the tooth case, be arranged in steering shaft in the tooth case, two groups of wheel steering assemblies with deflection angle and Steering gear, the Linkage steering that is connected two deflection angles forms with the universal-joint fixed strip that is connected two Steering gears; The place connects the pendulum with axis hole in the middle of the described Linkage steering, and the steering shaft bottom connects L shaped bar, and L shaped bar is inserted in the axis hole.
Described deflection angle is provided with spacing bone.
Compared with prior art, the perambulator bearing circle is fixed on one section of steering shaft on the perambulator foresteerage gear, L shaped bar on the steering shaft is enclosed within on the pendulum axis hole of Linkage steering, principle is when steering wheel rotation left the time, the pendulum that L shaped bar on the steering shaft promotes Linkage steering moves right, drive is rotated by the left and right wheel steering assembly that screw is assembled in the Linkage steering two ends, thereby with the vehicle left-handed turning; When steering wheel rotation to the right the time, the pendulum that the L shaped bar on the steering shaft promotes Linkage steering is moved to the left, drive the left and right wheel steering assembly that is assembled in the Linkage steering two ends by screw and rotate, from but the vehicle right-hand turning.
Assembling mode of the present utility model has following several big advantage:
1, simplifies production technology;
2, ease of assembly;
3, reduce production costs;
4, enhance productivity;
5, reduced the probability of scraping the festooned vehicle face.
Description of drawings
Fig. 1 is the wire frame exploded view of the utility model perambulator foresteerage gear.
Fig. 2 is the utility model perambulator foresteerage gear integral installation figure.
Among the figure: 1-left wheel steering assembly; The right wheel steering assembly of 2-; The 3-Linkage steering; The 4-steering shaft; 5-universal-joint fixed strip; 6-tooth case; 7-left steering column sleeve tube; 8-right steering column sleeve tube
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The specific embodiment
As shown in Figure 1, left and right wheel steering assembly 1 and 2 is welded by left and right deflection angle a1 and a2 and left and right Steering gear b1 and b2 respectively.Left and right deflection angle a1 and a2 are provided with spacing bone c and d.Linkage steering 3 is welded by Linkage steering iron plate e and pendulum f, and pendulum is provided with axis hole g.Steering shaft 4 is welded by axial axis h and L shaped bar i.The left and right two ends of universal-joint fixed strip 5 are provided with axis hole j1, the j2 of corresponding left and right Steering gear and fixing screw hole k1, k2, l1, the l2 of perambulator foresteerage gear at the bottom of car.
Linkage steering 3 uses the key screw corresponding screw hole m1-n1 in the left and right sides, m2-n2 to assemble with left and right wheel steering assembly 1,2.Put a pad between Linkage steering 3 and left and right sides deflection angle a1, a2, the pad purpose is to make it swing freely.Axis hole j1, the j2 of the corresponding left and right sides of universal-joint fixed strip 5 green phases Steering gear are enclosed within on the left and right wheel steering assembly 1,2.Equally, between universal-joint fixed strip 5 and left and right wheel steering assembly 1,2, put a pad and make it swing more freely.
As shown in Figure 1, the lower end end of left and right Steering gear b1, the b2 of left and right wheel steering assembly 1,2 inserts corresponding left and right Steering gear sleeve 7,8 centre hole o1, o2.Use screw, the corresponding screw hole k1 of green phase, k2, l1, l2 are fixed in universal-joint fixed strip 5 at the bottom of the car.At last axial axis 4 is enclosed within on the axis hole g on the pendulum f of Linkage steering 3, finishes the assembling of perambulator foresteerage gear.
As shown in Figure 1, wheel is contained in left and right wheel steering assembly 1,2 left and right Steering gear b1, the wheel shaft p1 of b2, p2 place.Tooth case 6 is fixed on the steering shaft 4.
When hand rotation perambulator bearing circle left the time, the pendulum f that L shaped bar i on the axial axis 4 promotes Linkage steering 3 moves right, thereby drive the left and right wheel steering assembly 1,2 that is fixed together with Linkage steering 3, right wheel steering assembly 2 inboards are provided with spacing bone d, and purpose is to make perambulator foresteerage gear rotating certain angle no longer to rotate; Other to the right the time when rotating the perambulator direction, L shaped bar i on dish deflecting bar 4 promotes the pendulum f of Linkage steering 3 to left movement, thereby drive the left and right wheel steering assembly 1,2 that is fixed together with Linkage steering 3, left wheel steering assembly 2 inboards are provided with spacing bone c, when forwarding certain angle to be, spacing bone c is stuck on the Linkage steering 3, no longer rotates.
