The side of the trailer to the single-track vehicle

 

(57) Abstract:

The invention relates to vehicles, the design of the lateral one-wheeled trailers for bicycles. The side of the trailer includes a frame with a wheel and joints of the trailer frame with the frame of the bike. Joints made in the form of hinges and traction. The hinges have the ability to rotate one frame relative to another in a vertical plane. Thrust made telescopic. In the process, you can control its fixation. The proposed solution ensures the stability of single-track vehicle side trailer. 3 Il.

The invention relates to velotron, namely to design the lateral one-wheeled trailers to single-track vehicles - bikes manufactured by the domestic industry, and may find application in the transportation of various household goods (up to 50 kg) in settlements in rural areas, tourism, etc.

Side trailers, with one wheel, single-track vehicles-bikes, are known (see , for example, ABT. mon. USSR N 1206166 "Side trailer single-track vehicle class. MKI B 62 K 27/12, publ. BI N 3, 1986; U.S. Pat. USA N 3186732, "the dust, attached to the bike in the back and provided with two wheels: "Valorized Bee-2", "Saransk mechanical plant", RIDB 450975. 003 ER, 1994; "Valorized VP-100", Minsk motor plant, THE 3750 7028-56.

However, single-track vehicle with such side trailers are rigid system that does not allow the rider cornering or rough road to tilt the bike in the right direction to preserve equilibrium in the absence of a sufficiently large cargo on the trailer (i.e. contrast).

Single-track vehicle with a trailer behind still have this option due to the articulated connection of the trailer to the frame of the bike. However, this scheme significantly increases the requirements and road conditions, and to the fitness of the cyclist, as the stability of the bike can be done only during its movement, and the beginning of its movement and its continuous maintenance counteracts the resistance of the towed trailer. Moreover, a two-wheeled trailer has limited stability and permeability, roughly corresponding stability and permeability of a tricycle.

Closest to the proposed technical solution aseptica (side stroller) to the single-track vehicle (bike) is mounted to the frame of a conventional two-wheeled bike.

To ensure the strength of an oblique rod, rigidly connected with the frame of the trailer and the frame of the Bicycle in place under the seat.

The frame of the trailer is also rigidly attached to the bike by using bars of different size. Due to the replacement of slats frame may fall or rise in accordance with the diameter mounted on the trailer wheels, thereby changing the clearance and the location of the center of gravity of the trailer and transported cargo.

Problem which is solved by the invention, as the author points out, is to create a lightweight trailer, with easily removable node of its accession to the usual bike and detach, providing the possibility of changes in clearance and lowering the center of gravity of the trailer and cargo.

However, the design has the main disadvantage inherent in all single-track vehicles, equipped with a unicycle side trailer: the design is unstable in the absence of cargo, and if there is sufficient load resistance increases, but remain substantial limitations on movement speed, curve radii and side roll on the road irregularities to an even greater extent than when driving a tricycle.

The problem is solved due to the fact that in the side of the trailer to the single-track vehicle, mainly to the bike, containing a frame with a wheel and joints of the trailer frame with the frame of the bike, the nodes connected in the form of a hinge can be rotated one frame relative to another in a vertical plane, and the thrust is made telescopic with the ability to control its fixation in the process of moving, and between moving and stationary parts placed a pre-compressed elastic element.

The invention is illustrated by drawings, where:

in Fig. 1 - General view (isometric) side is

The side of the trailer 1 to bike 2 consists of a frame 3 of the trailer 1, the wheel 4 fixed to the frame 3. Frame 3 trailer 1 is connected with the frame 5 bike 2 by means of two hinges 6, spring suspension 7 (Fig. 3), thrust 8 and led, for example, elastic carrier 9. Rod 8 is connected with the frames 3 and 5, the hinge eyes 10 (Fig. 2).

The hinges 6 is made to rotate in the vertical plane of the frame 5 of the Bicycle 2 and the frame 3 of the trailer 1. The nodes connecting the frame 3 of the trailer 1 to the frame 5 bike 2 can have different designs and are not the subject of the present invention, therefore, are not described in detail.

For convenience, the hinges 6 and the upper hinge lug 10 have quick fingers 11 (Fig. 2, 3) by removing the trailer easily detaches from transient nodes remaining on the bike; the detached trailer with load or without it relies on a folding bipod 12, and transition nodes do not interfere with use of the Bicycle as usual.

In Fig. 2 depicts the rod 8 with its fastening elements.

Rod 8 is made telescopic, for example the rod in the tube, and consists of two parts: the outer stationary 13 and the inner - mobile - 14. Between the parts 13 and 14 through the spacers 15 of the mouth is on empirically.

Telescopic rod 8 has a locking device consisting of the stopper 17 and the brake sleeve 18, which latching telescopic rod 8 and the whole system become hard.

For management purposes, the locking device through a thin elastic rod 19 is connected to the handle 20 fixed to the frame 5 of the bike at the helm.

The Assembly and operation of the device is as follows.

Frame 3 trailer 1 with the wheel 4 is attached to a manufactured bike for adults with closed frame. The frame 3 is attached to the frame 5 of a Bicycle by means of hinges 6, spring suspension 7 and elastic drove 9, then rod 8 connects the hinge lugs 10 and quick fingers 11 to the frame 3 of the trailer and the frame 5 of the bike at the point under the seat.

On the upper cross member of the frame 5 bike 2 secures the handle 20, which controls the stopper 17. Spring suspension 7 and elastic drove 9 to reduce road inertial load on the bike transported on the trailer 1 cargo. When transporting goods on the frame 3 trailer 1 the stability of the vehicle can be ensured by obtaining the equilibrium system, and when the maximum allowable cargo securing cyclist chooses the driving mode.

So, if the load on the trailer 1 is missing or it is small, and road conditions difficult, the control handle 20 is in position release the stopper 17, which provides a mode of motion, similar to the two-wheeled bike, i.e., the resistance is provided as usual by tilting the bike in the right direction, while the spring 16, rasimas with a little effort, seeks to put the bike in the upright position, which allows the cyclist to stop the movement and balance (for example, when moving up the slope, stopping at traffic lights, for the rest).

If the movement takes place with the loaded trailer, then by turning the handle 20 of the telescopic rod 8 can be locked by the stopper 17 and the system turns into hard tricycle, and the spring 16 will capture the system bike - trailer and turning it into a three-wheeled vertical position of the bike.

Brake sleeve 18 is a guard against accidental overloads in the system of the bike-trailer, allowing slippage of the movable part 14 thrust 8 relative to the brake sleeve 18.

The proposed solution provides by turning the control knob stop, rest p / is P CLASS="ptx2">

Thus, due to the technical solutions provided by the stability of single-track vehicle side trailer with cargo, and without it, including when driving in difficult road conditions.

The side of the trailer to the single-track vehicle, mainly to the bike, containing a frame with a wheel and joints of the trailer frame with the frame of a Bicycle, wherein the nodes are connected in the form of a hinge can be rotated one frame relative to another in a vertical plane and the thrust is made telescopic with the ability to control its fixation in the process of moving, and between moving and stationary parts placed a pre-compressed elastic element.
