Abstract

The utility model discloses a small train without slip, which can be used for a small train for children in amusement equipment and can also be used for transportation means in mines, forest, etc. The wheels of the novel small train without slip are in a truncated cone shape, and driving wheels of a front and a back shafts are arranged in a reverse V shape. With the structure, the abrasion between wheels and rails can be greatly reduced as well as the energy consumption when a small train turns. The utility model has the advantage of flexible steering, high safety and reliability.

Description

Small train without slip

The utility model relates to a kind of no slippage puddle jumper, is applicable to the transportation means on ground such as children's puddle jumper in the recreation facility, mine forest.

Present puddle jumper, the antero posterior axis drive wheel adopts Cylinder shape, therefore, when turning driving, because inside and outside track arc length is unequal, and the medial and lateral vehicle wheel rotational speed equates, like this, cause two side drive wheel and track to produce very large-slip, make inside tire aggravation wearing and tearing, consume big energy simultaneously.

The purpose of this utility model provides a kind of no slippage puddle jumper, adopts the difference configuration of special formed wheel and antero posterior axis drive wheel, and the wearing and tearing that largely alleviated wheel and track have reduced expenditure of energy, turn to flexibly safe ready.

The utility model is realized in the following way: the Cylinder that changes existing puddle jumper drive wheel forms the garden taper type, and the antero posterior axis drive wheel is configured to relatively in twos, and wherein the front axle drive wheel is configured to frustum bottom, garden relatively; It is relative that the rear axle drive wheel is configured to frustum top, garden.Like this, the track of bend and straight portion can be laid on the same horizontal surface.Because drive wheel adopts the garden taper type and becomes the V-type configuration, puddle jumper is when negotiation of bends, vehicle body is influenced by bend power, the drive wheel diameter can move thereupon, front axle medial and lateral drive wheel is outwards moved, rear axle medial and lateral drive wheel moves inward, so the outer side drive wheel increasing diameter of track is big, and interior side drive wheel diameter reduces.So under same rotational speed, interior outer curve arc length different situations, the arc length that outer side drive wheel contact diameter is passed by equates neutral angle with the arc length that interior side drive wheel contact diameter is passed by, thus the slippage problem of having avoided puddle jumper when negotiation of bends, to occur.

Now in conjunction with schematic view illustrating:

Fig. 1 is puddle jumper walking states in straight rail;

Fig. 2 is puddle jumper walking states in curved track;

［ 1 ］ front axle track adjusting wheel, ［ 2 ］ front axle drive wheel, ［ 3 ］ rear axle track adjusting wheel, ［ 4 ］ rear axle drive wheel, ［ 5 ］ track.

The garden taper type is adopted in drive wheel ［ 2 ］, ［ 4 ］, and ［ 2 ］ become the forward V-type relative, and ［ 4 ］ become reverse V-type relative.Fig. 1 is the straight rail walking states, because garden taper type design-calculated ［ 2 ］, ［ 4 ］ have self directional tagging, so ［ 1 ］, ［ 3 ］ and discord ［ 5 ］ contact have reduced the wearing and tearing of ［ 1 ］, ［ 3 ］ and ［ 5 ］; ［ 2 ］, ［ 4 ］ self become reverse V-type configuration in addition, so wheel increases the track positive pressure, so guaranteeing under certain tractive force situation, can alleviate the headstock deadweight.Fig. 2 is the negotiation of bends state, in the turning process, the outside ［ 2 ］, ［ 4 ］ diameter increase, inboard ［ 2 ］, ［ 4 ］ diameter reduce, under the identical situation of vehicle wheel rotational speed, the outside ［ 2 ］, ［ 4 ］ the arc length of passing through greater than inboard ［ 2 ］, ［ 4 ］ arc length of passing through, the interior outside through arc length right neutral angle equal, thereby avoided the slippage of puddle jumper when negotiation of bends, alleviated the wearing and tearing of ［ 2 ］, ［ 4 ］.

The utility model is reasonable in design, has solved well the old problem of mini train bend slippage, and the wearing and tearing that alleviated wheel make mini train economy and durability, novel reliable.

Claims

1, a kind of no slippage puddle jumper is characterized in that described front and back drive wheel adopts the garden taper type.Wherein the front axle drive wheel is configured to frustum bottom, garden relatively, and it is relative that the rear axle drive wheel is configured to frustum top, garden.
