Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a model truck.

[0002]

2. Description of the Related Art A railway model has O (32
mm), HO (16.5 mm), N (9 mm) gauge, etc. In particular, the N gauge is widely used because it is small and can be freely run and enjoyed with a relatively small layout. . The railroad model running system supplies positive and negative currents to the left and right rails, and on the vehicle side, it collects power from the left and right rails to drive the installed motors by collecting the drive wheels, axles, and frames respectively. And drive. Therefore, it is necessary that the wheels always run in good contact with the rail surface.

[0003]

By the way, the model railroad usually has a curved rail in order to normally drive an automobile by forming an endless layout. In a small layout or a complicated layout, a sharp curve with a small radius is used. Many rails are used. On the other hand, vehicles with long bodies such as locomotives, passenger cars, trains, etc. are considered bogie trucks and can pass relatively easily even on sharp curves.

However, since the model vehicle is structurally largely different from the actual vehicle, it is often difficult to drive on a curve.
For example, in an electric vehicle equipped with a motor called Moha, the motor is mounted on the floor plate, and the driving force is transmitted from the worm fixed to the rotating shaft to the gear of the axle via the worm wheel provided on the trolley. It is considered as a structure. Therefore, the worm shaft (motor) is fixed to the vehicle body,
Since the worm wheel (carriage) rotates, the meshing angle between these worms and the worm wheel changes in a curve, making it difficult for the car to rotate and derailing easily. In addition, the driving force cannot be smoothly transmitted from the worm to the worm wheel, and the running performance deteriorates.
In particular, a double shaft motor is mounted in the center of the floor plate, and all shafts (4 In the (axis) drive structure, the front and rear bogies are less likely to rotate due to the reasons described above, and therefore derailment is more likely to occur when traveling on a curve as compared with a structure in which only one bogie is driven (biaxial drive).

Further, when traveling at a high speed on a sharp curve, the inner wheels are easily lifted up from the rail surface, which makes it difficult to collect current. When the drive wheels are lifted from the rail surface, the frictional force with the rail surface is drastically reduced, the traction force is significantly reduced, and the current collection is poor, which hinders traveling. The present invention has been made in view of the above points, and an object of the present invention is to provide a railroad model bogie capable of favorably traveling on a curve having a small radius with a simple configuration.

[0006]

In order to achieve the above object, a railroad model truck according to a first aspect of the present invention is a first model in which a supporting member is provided upright substantially at the center of the upper surface of each frame that supports at least two shafts. , A second trolley and a connecting member having both ends rotatably attached to the upper surface of each support member of the trolley to connect the trolleys.

According to a second aspect of the present invention, the connecting member is bent upward at a substantially right angle in the vicinity of both ends of the flat plate, and is horizontally bent at a substantially right angle to form a substantially downward convex shape. Characterize. In claim 3, at least one of the first and second bogies is a power bogie.

Since the first and second carriages are rotatably connected to both ends of the connecting member by the supporting members provided upright on the frame, respectively, even if the distance between the carriages is large, the curves are curved. It becomes possible to follow the rail satisfactorily, it is possible to easily run on a sharp curve, and each cart can freely rotate without being restricted by the connecting member.
The wheels are hard to separate from the rail surface, which enables good current collection. As a result, it becomes possible to drive at high speed even on a sharp curve (Claim 1).

The connecting member for connecting the two carriages is bent upward at a substantially right angle in the vicinity of both ends thereof and further horizontally bent at a substantially right angle so as to have a substantially convex downward shape. Can be fixed to the floorboard, and the inside of the car can be widened,
Not only does it look good, but it can also accommodate seats, passengers, etc. (Claim 2). Further, by using at least one of the two carriages as a driving carriage, it can be made into an electric vehicle, and it becomes possible to travel with only one carriage.
