Description

Auxiliary wheel apparatus of auto bicycle

The present invention relates to the usage plan of 2002 Utility Model Registration Application No. 6663, filed by the applicant, and more specifically, to a secondary wheel device of a two-wheeled vehicle that can be selectively used in parking, pause, slow motion, and bad weather. The hydraulic cylinder is operated by installing an arm with a subsidiary wheel mounted by a bracket on both sides of the rear wheel of the car as a bearing, and hinged the end of the piston rod and the end of the hydraulic cylinder, respectively, between the upper center of the arm and the rear frame of the vehicle. As a result, the piston rod is moved up and down to rotate the arm equipped with the auxiliary wheel so that the auxiliary wheel can be grounded or raised to the body of the motorcycle.

In general, two-wheeled vehicle is a vehicle driven by a driving means composed of front and rear wheels, and it is possible to drive narrow roads by using the center of gravity and the steering shaft of the front wheels when driving. Although it has characteristics, it is necessary to support the vehicle by grounding the driver's feet to the ground when pausing or driving slowly in the city, and in the case of bad weather, ie snow or rainy weather conditions, it is composed of two wheels. Due to instability, the situation should be maintained using the driver's feet.

The conventional two-wheeled vehicle is equipped with a stand using the spring force of the spring between the front and rear wheels to pause the vehicle or to lower the stand when parking, the driver can push the vehicle to the rear to support by the stand and to drive When the vehicle supported by the stand was pushed forward, the stand was lifted by the spring force and the vehicle could be driven by the gear after starting.

In the conventional two-wheeled vehicle as described above, the stand can be used only when the vehicle is completely stopped or parked. When the engine capacity of the two-wheeled vehicle is 250CC or more, it is very difficult for the driver to support the vehicle or push it forward and backward by the force of the driver alone. it's difficult.

In addition, the conventional two-wheeled vehicle has a problem that not only is inconvenient but also a risk of a safety accident because it cannot use a stand when the vehicle is temporarily stopped while driving and relies on the driver's foot even in a slow or bad weather.

Therefore, the present invention was devised for the purpose of improving the conventional problems as described above. By operating the hydraulic operation switch of the handle part or the pedal of the footrest, the driver lowers the weight of the vehicle because the driver lowers the auxiliary wheel. There is no need to push or support, and optional use of the auxiliary wheel with simple operation in parking, pause, slow motion and bad weather provides convenience to the driver and effective use even for novice driver's lessons. It is to provide an auxiliary wheel device that can be prevented.

In order to provide the auxiliary wheel device described above, an auxiliary wheel in an idle state is mounted to the body of the vehicle by bearing the arm mounted by the bracket on both sides of the rear wheel front of the two-wheeled vehicle, and a piston between the upper center of the arm and the rear frame of the vehicle. The piston rod is moved up and down by the hinge of the rod end and the end of the hydraulic cylinder, respectively, and the auxiliary wheel can be rotated and operated to ground the auxiliary wheel to the ground or lift it to the body of a two-wheeled vehicle. It is possible to provide an auxiliary wheel device.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the state of the present invention is mounted on the rear wheel front of the two-wheeled vehicle showing the state of use of the present invention, Figure 2 is a perspective view of the present invention showing the overall structure of the auxiliary wheel device. 3 is a view illustrating a structure in which an arm equipped with an auxiliary wheel rotates by an operation of a piston rod and a hydraulic cylinder hinged between an upper center of an arm and a rear wheel frame of a vehicle, respectively.

In the two-wheeled vehicle B driven by the front wheel F and the rear wheel R,

Auxiliary wheels 10, 10 'in the idle state on both sides of the rear wheel R are mounted with bearings 22, 22' with bent arms 20 mounted by brackets 11, 11 '. And hinge the front end of the piston rod 21 and the front end of the hydraulic cylinder 31 between the upper center of the arm 20 and the rear wheel frame 30 of the vehicle, respectively, to operate the piston rod 21 by operation of the hydraulic cylinder 31. ) Is a structure that allows the arm 20, on which the auxiliary wheels 10 and 10 'are mounted, to be rotatable and operated to move up and down.

It is also possible to rotate the arm 20 by the piston rod 21 using a pneumatic cylinder (not shown) in place of the hydraulic cylinder 31 described above.

In this way, the present invention provides convenience to the driver by allowing the driver to support and maintain the center of the vehicle without parking the two-wheeled vehicle (B), or during driving, pausing and slowing, and in bad weather. The two-wheeled vehicle (B) can be used safely.

As described above, while driving the two-wheeled vehicle (B), in the case of parking, pause, slow motion and bad weather, the auxiliary wheel (10) by operating a pedal of the hydraulic operation switch or footrest installed in the handle portion of the two-wheeled vehicle (B) ( When the 10 ') is lowered and landed on the ground, the auxiliary wheels 10 and 10' support the two-wheeled vehicle B on both sides between the front wheels F and the rear wheels R to maintain the center. When the pedal of the hydraulic operation switch or the footrest is operated, the hydraulic cylinder 31 hinged to the front wheel frame 30 of the vehicle is operated.

At this time, the piston rod 21 hinged to the upper center of the arm 20 is advanced, and the arm 20 is rotated forward to be idled by brackets 11 and 11 'on both sides of the arm 20. The secondary wheels 10 and 10 'coupled to the ground are grounded to support the two-wheeled vehicle B.

It is coupled to the body of the vehicle by bearings 22 and 22 'on both upper sides of the arm 20 to facilitate the rotation operation of the arm 20.

If the auxiliary wheels 10 and 10 'are not needed in normal driving, when the hydraulic operation switch or pedal is operated again, the hydraulic cylinder 31 is operated to reverse the piston rod 21 and accordingly the hinged arm. (20) reverse rotation operation so that the auxiliary wheels (10) and (10 ') hinged to the brackets (11) (11') of the arm (20) are raised to the body portion of the vehicle so that the front wheel (F) and the rear wheel (R). It is possible to prevent the obstacle to the side of the two-wheeled vehicle (B) running by) and to run.

In addition to the above-described hydraulic cylinder 31, in another embodiment, an auxiliary wheel may be used by operating a piston rod using a pneumatic cylinder to rotate the arm forward and reverse.

The above operation raises and lowers the auxiliary wheel by manipulating the hydraulically operated switch or pedal without parking the vehicle or stopping and slowing the vehicle while driving and when the driver needs to keep the center of the vehicle. Can be used to descend.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, the present invention allows the driver to easily operate the hydraulically operated switch or pedal to lower the auxiliary wheel of the two-wheeled vehicle so that the driver does not need to push or support a heavy vehicle, and is suitable for parking, pausing, slowing and bad weather. By selectively using the auxiliary wheel with a simple operation, it is possible to provide convenience to the driver and effectively use it even when teaching a novice driver, thereby preventing safety accidents.
