The invention relates to vehicles with a muscular drive and can be used for movement.

Famous bike with a linear actuator consisting of a frame with a seat installed on the front swivel wheel that is installed in the fork with the wheel, mounted in bearings of the frame and the rear drive wheel sprocket unit freewheel and manaton the shifter. While on the frame in bearings mounted shaft with a leading asterisk, connected by a chain with one of the sprockets of the drive wheel. When this shaft with a leading asterisk on both sides it is provided with two crank-beam mechanisms, cranks which are opposed to each other. To the middle part of each connecting rod crank-beam mechanisms attached to the pedal.

The rods crank-slider mechanisms spaced apart from each other a distance greater than the width of the seat and the pedals are attached to the inner surface of the connecting rods. Thus the axis of the front wheel is made with a through hole, and the shaft connecting the crank-slider mechanisms, passed through this hole. Guides for the ends of rods can be articulated vertical beam, each of which one end of the hinge attached to the connecting rod, the other end of the hinge is attached to the bracket attached to the frame behind peredne the wheel (see patent RU No. 2400391)

The disadvantage of this bike is a complicated structure due to the threading shaft through the hub of the front wheel and too long a chain.

Closest to the claimed is the bike recumbent with a linear actuator, comprising a frame with a seat mounted on a front swivel wheel that is installed in the fork with the wheel, mounted in bearings of the frame and rear wheel with sprocket unit freewheel and manaton the shifter on the frame on the removal of the front wheel bearing has a shaft with a leading asterisk, connected by a chain with one of the sprockets driving the rear wheels, while the shaft with a leading asterisk on both sides it is provided with two crank-beam mechanisms, cranks which are opposed to each other, and to each L-shaped horizontal rod on the end attached to the pedal (see JP 2009 - 119914, A).

The disadvantage of this invention is a long chain with many of deflecting rollers and the inability to quickly change the driver, so as not provided for changing the distance from the back of the seat to the pedals.

The aim of the present invention is the ability to quickly adjust the distance between the backrest and the foot pedal for a specific driver and shortening the chain.

This goal is achieved by the fact that the bike Ricambi is t with a linear actuator, including a frame with a seat mounted on a front swivel wheel that is installed in the fork with the wheel, mounted in bearings of the frame and rear wheel with sprocket unit freewheel and manaton the shifter on the frame in bearings mounted shaft with a leading asterisk, connected by a chain with one of the sprockets of the drive wheel, the shaft with a leading asterisk on both sides it is provided with two crank-beam mechanisms, cranks which are opposed to each other, and to each rod at the end of the crank-beam mechanisms attached to the pedal, wherein each swivel rocker the attached end to the collar with a Cam or a screw located on the horizontal guide tube attached to the frame bracket located between the front and rear wheels, and the shaft with the leading asterisk is located between the front and rear wheels near the front wheel, and the connecting rods are made straight and are arranged vertically and each crank of the crank-beam mechanism pivotally attached to the middle part of its vertical and rectilinear rod.

The invention is illustrated by drawings.

Figure 1 depicts the bike recumbent, side view.

Figure 2 - section A-a in figure 1 depicts the crank-beam mechanisms with pedal the mi.

Figure 3 - cross-section B-B figure 1 depicts the clamp with eccentric.

Bike recumbent with the linear actuator includes a frame 1, a seat 2 mounted on the rear drive wheel 3 and the front swivel wheel 4. In the frame 1 in bearings installed plug 5 with the wheel 6 swivel casters 4.

On the frame 1 in bearings 7 mounted shaft 8 with the leading sprocket 9 and the opposed installed cranks 10 and 11 of the crank-beam mechanisms, the connecting rods 12 and 13 which are installed approximately vertically and is attached by hinges with axes 14 and 15 and the bearings 16 and 17 to the cranks 10 and 11 with the middle part. With one of the upper side to the ends of rods 12 and 13 attached to the pedals 18 and 19.

On the other lower side of the ends of rods 12 and 13 are attached by hinges with axes 20 and 21 and the bearings 22 and 23 to the beam 24 and 25. About a horizontal beam 24 and 25 other ends of the fixed hinge axis 26 and 27 to the collar 28, is made with a clamp in the form of a Cam disk 29 or screw. The clamp 28 is clamped on the rail a horizontal pipe 30, which is fixed by a bracket 31 to the frame 1 between the front wheel 4 and the rear wheel 3.

The rear wheel 3 provided with a sprocket unit 32 with the ratchet and manaton the shifter 33. The drive sprocket 9 is connected by a chain 34 with one of the sprockets of the sprocket unit 32. The trajectory described by each pedal (shown puncture is), like an oval, flattened at the bottom.

The trajectory of the pedals more convenient and efficient than circular.

Does the bike as follows.

The driver pedals 18 and 19 and controls the wheel 6. When changing the driver, a new driver can instantly adjust the distance between the seat and the pedals under his feet length by moving the clamp 28 and clamping his eccentric 29. It is much easier to move seats.

Stated the bike has a simple design, efficient drive and short circuit. Change the driver can be done instantly, which is especially valuable when the car recumbent.
