Single recumbent

The invention relates to vehicles with a muscular drive. Known single-track vehicle with a body and a motor Acabion GTBO"containing a frame with a seat mounted on a front swivel wheel and rear drive wheel, while on the sides of the rear wheel pivotally attached to two levers with wheels

(see http://www.membrana/articles/technic/2008/02/08/180300 .htlm).

However, this vehicle small wheels are used only to maintain when you start and when you stop and cannot prevent overturning of the vehicle lateral gust of wind.

Closest to the claimed is the bike contains a frame with a seat mounted on the rear drive wheel and the front swivel wheel, fork which is fixed with its axis in bearings of the frame, a carriage attached to the frame, with rods and pedals and a leading asterisk, a circuit associated with one of the sprockets of the sprocket unit rear wheels, ratchet and shifter on the frame in bearings installed horizontal axis, which are attached to the housing, the bearings of which is the vertical axis of the steering wheel with arms covering the seat, while the end of the horizontal axis is equipped with a lever, which is provided with lever, ball joint, planet carrier, the second is aravim hinge, the second lever is connected with the rotation axis of the fork of the front wheel. While rocking the wheel associated additional rod with one of the rods of the carriage

(see http://ihpv.free.fr/myihpv/pdf/4powerbikes.html).

However, this bike when equipping the body of the fairing can be easily overturned a side gust of wind, including from passing truck.

The aim of the present invention is the elimination of rollover of the vehicle lateral gust of wind.

This goal is achieved by the fact that a single recumbent containing a frame with a seat mounted on the rear drive wheel and the front swivel wheel, fork which is fixed with its axis in bearings of the frame, a carriage attached to the frame, with rods and pedals and a leading asterisk, a circuit associated with one of the sprockets of the sprocket unit rear wheels, ratchet and shifter on the frame in bearings installed horizontal axis, which are attached to the housing, the bearings of which is the vertical axis of the steering wheel with arms covering the seat, while the end of the horizontal axis is equipped with a lever, which ball joint, planet carrier, the second ball joint, a second lever connected with the rotation axis of the fork of the front wheel.

What's new is that to the frame on each side of the rear wheel hinges attached two levers on concoctor on the axes of the wheels are, each lever with the wheel with the middle part connected to the frame by two hinge links, and the axis connecting the articulated links pivotally connected with a thrust that his middle pivotally attached to the housing, which is installed in bearings axle steering.

With the purpose of storing energy during the descent to return her to drive while climbing a mountain, and increase the stability of the vehicle due to the promotion of the side wheels, and due to their gyroscopic moment of wheels attached to the levers on the inner side and with the help of fasteners attached disks resting on the rear drive wheel, the axis of the hinge levers are tilted so that their wheels in their upper portions inclined to drive the rear wheel.

To facilitate lifting of the arms with wheels and increasing the pressing force of drive to the rear wheel levers with wheels connected to the frame by springs, and are interconnected by a spring.

To prevent possible slippage of the drive wheel when lowered side wheel rear drive wheel mounted on the suspension pivotally attached to the frame, this pendant is connected with the frame buffer.

The invention is illustrated in the drawing.

4 is a cross-section B-B Fig.

Single-track tricycle includes a frame 1, a seat 2 mounted on the rear drive wheel 3 and the front swivel wheel 4, the plug 5 which is fixed with its axis 6 in bearings of the frame 1. To the frame 1 attached to the carriage 7 with the connecting rods 8 and 9 and the pedals 10 and 11 and the leading asterisk 12, which circuit 13 is connected with one of the sprockets of the sprocket unit 14 of the rear wheel 3 with the ratchet and the gear 15. On the frame 1 in bearings 16 mounted horizontal axis 17, which are attached to the housing 18, the bearings 19, which is the vertical axis 20 of the steering wheel 21 with the arms 22 and 23 covering the seat 2. The end of the horizontal axis 17 is equipped with a lever 24, which is a ball joint 25, the planet carrier 26, the second ball joint 27, the second lever 28 is connected with the rotation axis 6 of the plug 5 of the front wheel 4.

On the sides of the rear wheels 3 by means of hinges 29 and 30 attached to two levers 31 and 32, the ends of which the axes 33 and 34 mounted wheels 35 and 36. Each lever 31 and 32 with the middle part is connected with the frame 1 by two hinge links 37 and 38 with the axes 39, 40 and 41. Each axis 40, a hinge connecting links 37 and 38 pivotally connected with a thrust 42, and in its middle is attached hinge axis 43 to the housing 18.

Wheels 35 and 36 are attached to the levers 31 and 32 on the inner side, and with fasteners 44 and 45 attached diski and 47, based on the tire of the rear wheel 3 and included him in frictional engagement. The axis of the hinges 29 and 30 is angled so that their wheels 35 and 36 with their upper portions inclined to the drive wheel 3.

To facilitate lifting of the levers 31 and 32 with wheels 35 and 36 each of these levers is connected with the frame 1 by a spring 48. To increase the clutch disks 46 and 47 with the tire of the rear wheel 3 levers 31 and 32 are connected by a spring 49, which presses the disks 46 and 47 to the wheel 3 at the expense of play in the hinges 29 and 30.

To prevent slippage of the drive wheel 3, with the lowered rear wheels 35 and 36, the drive wheel 3 mounted on the suspension 50 pivotally attached to the frame 1 axis 51. Suspension 50 is connected to the frame 1 of the shock absorber 52.

Rotate the housing 18 on the axis 17 is limited by a stop 53. Given the emphasis of the housing 18 in the stop 53 of the hinge links 37 and 38 stand in an almost vertical position with a small inclination from the direction of the stop 53, and may perceive the compression load lowered, the wheels 35 and 36. In this position, the tricycle can start and stop.

The tricycle is equipped with a body 54. The disks 46 and 47 can be provided with holes in the centre to release them from engagement with the tire of the wheel 3 at the upper position of the wheels 35 and 36.

Works recumbent as follows.

The driver sits on the seat 2, and starts to pedal 10 and 11. At this time, the lever 31 is 32 with wheels 35 and 36 are omitted and not give recumbent fall. As speed increases, the driver turns the steering wheel 21 on the axis 17 on himself, lifting levers with wheels 35 and 36. When driving downhill, he can raise the levers with wheels above, entering into engagement with the rear wheel 3 discs 46 and 47, through which fasteners 44 and 45 are spinning wheels 35 and 36, as we ascend, all with greater and greater speed of storing energy. With the further rise of the disks due to their Central openings are out of engagement with the wheel 3, and the energy of the rotating wheels may persist long enough.

When driving uphill, the driver turns the steering wheel 21 on the axis 17 and the discs 46 and 47 are in engagement with the tire of the wheel 3, transferring the energy of the rotating wheels on the drive wheel 3. As lowering of the wheels 35 and 36, the speed drops as the point of engagement moves to the edge of the disks 46 and 47. With a sharp sideways gust of wind, for example from passing truck, when the driver feels that the recumbent leans, he sharply turning the steering wheel 21 to the stop 53 lowers the wheels 35 and 36 to the ground, preventing tilting recumbent. Greater stability of the tricycle also contribute promoted wheels 35 and 36, due to their gyroscopic moment.

For larger energy storage wheels 35 and 36, they can be equipped with additional balanced weights.

Management recumbent is turning parts, all specifications shall ω of the steering wheel 21 on the axis 20.

Stated a single recumbent is much safer and allows you to store energy on the slopes and give it to the lifts.
