Abstract

A toy vehicle, in particular for track-guided racetracks, is driven by an electric motor which cooperates via a first gear wheel provided on a drive shaft, with a second gear wheel connected to an axle shaft carrying wheels, where the distance between the drive shaft of the electric motor and the axle shaft is variable for the use of different first and second gear wheels such that different transmission ratios can be implemented.

Description

The toy car that is used for the autodrome of railway guidance

Technical field

The present invention relates to a kind of toy car, be particularly useful for the autodrome.

If except simple toy interest, its user can also can improve the value of a toy car thus by the repacking measure influence mechanical property of travelling targetedly on above-mentioned car.At first be for also can acquire an education the thus knowledge of technology/physics aspect of learning of younger user.

Background technology

By the known electric motor car that is used for vehicle model racing car of DE 34 29 539A1, it has slit guiding and sliding-contact track, and this electric motor car is furnished with the motor of two wheels of a rear axle of direct driving.Described motor is fixed on the support unit on a chassis.

By US 6,062,943 provide the toy car of an activity, are preferably used in an autodrome with guide rail, and this toy car has a motor that is used for rear axle.This motor is furnished with two driving shafts perpendicular to the car longitudinal extension, and its free end has driving-disc.These driving-discs directly and the rear axle wheel concur.

In DE 200 05 174U1, relate to a toy car that is used for the Car Track of a railway guidance, one of them motor car of laterally packing into.Described motor concurs by second gear of first gear and rear axle, and wherein first gear has the diameter littler than second gear.

Summary of the invention

The objective of the invention is, take such precautionary measures between the axletree to a motor being placed in a toy car and a driving shaft, make the torque of described motor and rotating speed adapt to definite track profile, described toy car moves on the track profile.But also should guarantee at this, can easily and by simple measure realize suitability.

For this reason, the present invention proposes a kind of toy car that is used for the autodrome of railway guidance, this toy car is by a motor-driven, this motor concurs with second gear that the axletree of a supporting wheel is connected by first gear that is positioned on the driving shaft, it is characterized in that, can change to use the first different gears with distance between the axletree at motor driving shaft, make it possible to achieve different speed reducing ratio.

The major advantage that realizes by the present invention is, the driving shaft of described motor and the distance between the axletree can be adjusted in order to change speed reducing ratio, because it mainly is to the interested youthful interest in game play optimization of technology that the described toy car of this technical pattern not only makes, and can make them obtain physics and mechanical knowledge.Owing to be used for the thrust bearing of axletree and it can realize the change of distance between the driving shaft in common mode at the suitable structural design scheme that holds body.Hold body at these these thrust bearings and its and be easy to conversion.At last, this point also is applicable to the framework that holds of motor on meaning, and this holds framework and concurs by a support of inserting connection and vehicle frame efficiently.

The specific embodiment

Toy car 1 is in order to constitute on the autodrome that operates in a unshowned railway guidance and to comprise a vehicle frame 2, this vehicle frame has back

axle unit

5 and 8, one intermediate supports 9 of a fore axle unit with front-

wheel

6 and 7 with trailing wheel 3 and 4 and extends between these axle units.Use a motor 10 in order to drive toy car 1, this motor of looking on travel direction A is arranged on the front of the axletree 11 of a back axle unit 5 that is connected with 4 with trailing wheel 3.Described motor 10 and its driving shaft 12 are provided with perpendicular to the vertical B-B of car.On driving shaft 12, fix one first gear 13, one second gear, 14 engagements of it and axletree 11.Distance A s between the axletree 11 of the driving shaft 12 of described motor 10 and back axle unit 5 can change, and specifically in order to use the first different gears 13, thereby makes it possible to realize different speed reducing ratio.Therefore can make second gear 14 be furnished with 5 teeth and first gear 13 is furnished with 12 teeth or be furnished with 13 teeth as variation.

Described axletree 11 is surrounded (see figure 4)s by thrust bearing 15 and 16, and they are provided with and play by the corresponding layout in holding body 17 and 18 effect of the distance A s between the axletree 11 of the driving shaft 12 that changes motor 10 and back axle unit 5 spaced reciprocally.Make described thrust bearing 15 and 16 Rotate 180 ° (see figure 5) in holding body 17 and 18 for this reason.

Each thrust bearing 15 is positioned at and holds body 17 the insides accordingly and comprise a bearing section 19 that is used for axletree 11, and this bearing section 19 has a center Z1.The described thrust bearing 15 of looking from the side has the profile of a basic rectangle, and it has the bearing wall 22 and 23 of vertical bearing wall 20,21 and level.Center Z1 is different with As II with distance A sI between the vertical bearing wall 20 and 21, can correspondingly adjust the distance A s of driving shaft 12 and axletree 11 thus.Describedly in addition hold guide section 24 and 25 and backstops 26 that are used for each vertical bearing wall 20 or 21 that body 17 has the interval that is used for horizontal bearing wall 22 and 23.Sign 27 and 28 is set on thrust bearing 15, and they represent the number of

teeth

12 or 13 of effective first gear 9.On a vertical bearing wall 20 or 21, can also have definite part 29 and 30 widened.

The described body 17 and 18 that holds describes that at a basket that is used for motor receive framework 31 processes, and this holds framework and has a base plate 32,

sidewall

33,34 and an antetheca 35 and a rear wall 36.Described

sidewall

33 and 34 is near the

end walls

35 and 36 of motors 10, wherein said driving shaft 12 be in first gear 13 that function is connected with second gear 14 and protrude in sidewall 33.The thrust bearing 15 of described

axletree

11 and 16 passes through the fixed arm 37 and 38 fixed-site of an additional frame 39 in holding body 17 and 18.Described additional frame 39 puts in accommodating section 41 the inside holding between body 17 and 18 by a cross member 40 and the bolt Sch I that is provided with by the space and Sch II (see figure 6) are fixed on and hold on the framework 31.

Described motor 10, axletree 11 and trailing wheel 3 and 4 and hold body 31 and constitute back axle units 5, it is fixed on the intermediate support 9 of vehicle frame 2.Insert for one and connect 42 between back axle unit 5 and intermediate support 9 (seeing Fig. 3 and 4), should insert connect and have a chucking fork 43, this chucking fork 43 be after axle unit 5 the part that holds framework 31 and what embed a correspondence is storing apparatus 44 the insides of a rectangle in the present embodiment.At last, most advanced and sophisticated 47 and 48 the outside 45 and 46 is furnished with barb-

shaped part

49 and 50 widened, and they are bearing on the

abutment wall

51 and 52 of storing apparatus 44.
