Abstract

The utility model relates to a remote-controlled toy car of a front-wheel steering type, relating to a toy car, particularly a remote-controlled toy car of a front-wheel steering type. The utility model has the technical proposal that a motor gear can drive a sector gear to rotate through a drive gear, so that a deflector rod on the sector gear can swing; a rocker rod is fixedly connected with a knuckle arm which can drive front wheels to rotate. The utility model has the advantages of simple structure and flexible operation. The utility model can be used on all remote controlled toy cars with the function of directional control.

Description

Front-wheel steer formula remote-controlled toy vehicle

The utility model relates to a kind of toy car, refers to a kind of front-wheel steer formula remote-controlled toy vehicle especially.

Toy car is because its recreational strong extremely great kindness of children, yet, its steering often in use find indiscriminately ad. as one wishes controlling party to, and sometimes in use for some time, problem such as be partial to when straight forward occurring, bring unsatisfactory trouble to the user.

The purpose of this utility model is to provide a kind of front-wheel steer formula remote-controlled toy vehicle.

The utility model is achieved by the following technical solution: motor gear drives sector gear by travelling gear and rotates, and makes that the driving lever on the sector gear is swung, and driving lever is fixedlyed connected with pitman arm, and pitman arm drives front vehicle wheel and rotates.

The utility model is simple in structure, manoeuvrable, can use on all have the remote-controlled toy vehicle of direction control function, has broad application prospects.

Below in conjunction with accompanying drawing the utility model is further specified

Accompanying drawing 1 is the utility model structural representation

Accompanying drawing 2 is a side view of the present utility model

Accompanying drawing 3 is the micro-adjusting mechanism structure chart

Accompanying drawing 4 is the utility model outline drawing

See accompanying

drawing

1,2,3,4, the utility model comprises motor 1,

travelling gear

21,22, sector gear 3, driving lever 4, pitman arm 5, wheel 6, torsion spring 7, eccentric shaft 8, steering arm 9, fine tuning dish 10, car body 12.Motor 1 is installed on the car body 12, motor gear and

travelling gear

22,21 mesh in regular turn, travelling gear 21 and sector gear 3 engagements, the turning cylinder of sector gear 3 is installed on the car body 12, on on the sector gear 3, be fixed with a driving lever 4, in the groove that is fastened on the pitman arm 5 of driving lever 4, two of pitman arm 5 respectively be packed in car body 12 on steering arm 9 be connected, the other end of steering arm 9 is connected with wheel 6, and the two ends that are fixed on the torsion spring 7 on the car body 12 are folded in the both sides of pitman arm 5 upper grooves.Fine tuning dish 10 is installed on the car body 12, and the eccentric shaft 8 that sets firmly on it protrudes out among torsion spring 7, on the car body 12 before fine tuning dish 10, is provided with reticule 11.

When using the utility model, starter 1, motor gear drives

travelling gear

21,22, sector gear 3 rotates, the rotation of sector gear 3 makes the driving lever 4 on it deflect around the axle that rotates, and because driving lever 4 is fastened in the groove on the pitman arm 5, so driving lever 4 overcomes the torsion of the torsion spring 7 of groove both sides, make pitman arm 5 be moved, two ends owing to pitman arm 5 are connected with steering arm 9 respectively again, and steering arm 9 is connected with wheel 6, so make wheel 6 deflect, realize the action that toy car turns to, if stop the rotation of motor 1, then pitman arm 5 resets under the effect of torsion spring 7, and toy car keeps keeping straight on.

If toy car after using a time, is found the deflection phenomenon to occur in the craspedodrome process, then rotate fine tuning dish 10 on the car body 12 to the position of required graduation mark 11, the eccentric shaft of then fixing on it 8 is offset, make to drive torsion spring 7 deflections pitman arm 5 and move, thereby realize correcting the deflection phenomenon.
