Specific embodiment

Please referring to figure, in the utility model embodiment, a kind of model car steering wheel emulates linkage structure, including steering wheel 1, Steering wheel base 2, bracket 10, draw bar 11, tire support 14 and tire 15；It is worn on the central axis of the steering wheel base 2 There is inclined No.1 universal driving shaft 3, the upper end of No.1 universal driving shaft 3 is fixedly connected with steering wheel 1, rotates No.1 connection by steering wheel 1 The lower end of moving axis 3, No.1 universal driving shaft 3 is connected with No. two universal driving shafts 5 by linkage unit 4, and No. two universal driving shafts 5 is made to follow rotation, The helical structure 6 of integral structure is surrounded on the outside of No. two universal driving shafts 5.

It is fixedly installed with vertical bolt column 13 on the two sides of chassis of vehicle body 16, is arranged on bolt column 13 around its turn Dynamic tire support 14 is fixedly connected between the tire support 14 of two sides by horizontal draw bar 11；In draw bar 11 Vertical traction axle bed 12 is fixedly installed on one end between tire support 14, fixation is equipped with vertical in traction axle bed 12 Shaft 8 is drawn, the upper end of traction shaft 8 is fixed with horizontal traction fluted disc 7, and axis of traction is realized in the rotation by drawing fluted disc 7 The rotation of seat 12 makes draw bar 11 realize that displacement changes under the rotation of traction axle bed 12, to drive tire support 14 or so It swings；It is fixedly installed with horizontal bracket 10 on the bolt column 13, the traction fluted disc 7 is rotatablely connected on bracket 10, leads to The support traction fluted disc 7 of bracket 10 is crossed, promotion traction shaft 8 is rotated around it by traction fluted disc 7 and is swung.

The teeth 9 cooperated with helical structure 6, and helical structure 6 and teeth 9 are provided on traction 7 side of fluted disc Engagement drives teeth 9 to be moved forward and backward by the helical structure 6 of rotation, and driving traction fluted disc 7 rotates.

Tire 15 is installed on the tire support 14, is accordingly swung also with tire support 14.

Steering wheel 1 is fixedly connected with 3 one end of No.1 universal driving shaft, and No.1 universal driving shaft 3 passes through linkage unit 4 and No. two universal driving shafts 5 rotation connections, No. two universal driving shafts 5 of driving rotate when steering wheel 1 rotates, and No. two 5 circumferential directions of universal driving shaft are equipped with helical structure 6, Helical structure 6 can be by being engaged 7 turns of fluted disc of traction of realization driving with the teeth 9 on traction fluted disc 7 when No. two universal driving shafts 5 rotate It is dynamic, at this point, the traction shaft 8 of traction 7 integrally connected of fluted disc realizes rotation under the rotation of traction fluted disc 7, due to drawing shaft 8 The other end is fixedly connected with traction axle bed 12, and therefore, draw bar 11 realizes that displacement changes under the rotation of traction axle bed 12, thus Tire support 14 is driven to swing.

The angle for determining the rotation of steering wheel 1 is the distance between the fillet of screw on helical structure 6, when the two neighboring fillet of screw Distance get over hour, steering wheel 1 rotation once circle drive traction fluted disc 7 rotate angle it is smaller, in 14 amplitude of fluctuation of tire support In the case that degree is limited, equal tire swing angle, the distance of the two neighboring fillet of screw is got over hour, and steering wheel rotatably encloses Number is more, and certainly, 9 size of teeth drawn on fluted disc 7 at this time will be also correspondingly arranged with the fillet of screw of helical structure 6.

Steering wheel linkage structure uses engaged gears linkage mechanism, and steering wheel left-right rotation is at least up to 1.5 circles, maximum journey Degree reduces true vehicle steering wheel function effect, makes model car more close to true vehicle, more for interest and playing property.

In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiments being understood that.
