Muscular wheel drive vehicle

 

(57) Abstract:

Muscular wheel drive vehicle contains located in the housing (1) of the planetary gear with the planet carrier (3) and two satellites (6). Led (3) is made in the form of a sprocket chain drive and has two eccentric protrusion (5), one on each end surface. Tabs (5) spaced 180o. Satellites (6) mounted on the eccentric projections (5) are on the end surface on one support stud (8) for the transmission of muscular effort and kinematically connected with two fixed Central wheels (7) with internal teeth. The distance from the base of a stud (8) to the eccentric protrusion (5) and from the eccentric protrusion (5) to the axis of rotation of the carrier equal one-fourth the length of the stroke of the supporting stud (8). The proposed solution allows you to move the pivot studs (8) in a straight line and thus increases the usability of the vehicle. 1 Il.

The invention relates to transport machinery, namely, to drive vehicles for the transmission of muscle force to the working body, and can be preferably used in Bicycle production industry.

Known bassethound is elendra with pistons, Central eccentric sleeve bearing precast docrepository shaft. The shoulder of the first crank on one end plane of the shaft and the shoulder of the second crank on the other end of the plane is equal to the eccentricity of the sleeve. Formed the site of two parallel crank links - one shaft is inside the other. In the middle part docrepository shaft has a rigid connection with the small pinion gear that slides inside a large stationary gear. Thus the diameter of the small gear can be more than half of the diameter of the large gear. This design eliminates the formation of distortions in the gear mesh and unloads the teeth of wheels. Neck cranks are on the end planes of the crank shaft. During the rotation of the Central eccentric sleeve starts at the same time to make a planetary motion docrepository shaft, since it is rigidly connected with a small gear which engages with a fixed large gear. Resulting in neck cranks dvuhterabaytnogo shaft begin to move strictly straightforward pistons in the cylinders.

The vertical positioning of the crank shaft reduces the rigidity of the structure as a whole, creates additional autoblood, for example, on bicycles.

Closest to the technical nature of the claimed invention is a diagram of the planetary gear [2], including led and satellites. in the internal engagement with a fixed wheel and external engagement with the Central (sun) wheel.

The objective of the invention was to optimize the path of the point of application of muscular force, and, consequently, increase the ergonomic qualities of the vehicle.

This problem is solved as follows.

Muscular wheel drive vehicle contains accommodated in the housing of the planetary gear with the planet carrier and the two satellites on the end surfaces of which are located on the control pin for the transmission of muscular effort. The planetary carrier is made in the form of a sprocket chain drive with two eccentric protrusions, one on each end surface spaced at 180 degrees. The satellites are mounted on eccentric protrusions drove and kinematically connected with two fixed Central wheel with internal teeth, and the distance from the base of the spike to the eccentric protrusion and an eccentric projection to the axis of rotation of the sprocket muscular wheel drive vehicle is illustrated by a drawing.

The drawing shows a General view of the actuator in the section.

Muscle actuator includes a housing 1 with a cover 2, the sprocket chain gear 3 mounted in the bed 4. The sprocket 3 has an eccentric lugs 5, which are equipped satellites 6 in the internal engagement with the Central wheel 7. Satellites 6 bear on the end surfaces bearing spines 8 to transmit muscular efforts, provided for convenience pedals 9.

The drive works as follows. At the beginning of the movement of one leg cleat 8 is in its extreme upper position and the other at the bottom. When the transfer of force from the legs to the upper anchor cleat 7 associated satellite 6 starts planetary motion, simultaneously rotating the sprocket chain transmission and lower the satellite 6. While supporting the spikes move in a straight line. Using a chain transfer rotation is transmitted directly to the working body, for example, on the sprocket of the rear wheel of a Bicycle. Further operation of the actuator is carried by the reciprocating movement of the supporting studs 8. In the man's feet make a movement similar to shahaney on the spot. Actuator set-up possible at a certain angle to the longitudinal axis of the transport environment is about the cleat off the ground.

Prototype testing has shown that the most convenient for muscle actuator is the gear ratio between the satellite 6 and the Central fixed wheel 7 is close to two.

In order to ensure traffic safety, the actuator can be equipped with a ratchet mechanism to eliminate sudden braking.
