CN2615036Y - Accelerating power-saving device for tricycle by rider propulsion - Google Patents

Abstract

An accelerative and laborsaving apparatus for a manual tricycle adopts lever principle for easily and alternately trampling a left pedal and a right pedal. A pinion is driven by a long treadle rod via a chain-rod, a bent shaft, and a gearwheel, thereby rotating a chain-plate. A rotating flywheel is driven by a chain, thereby frontward driving the manual tricycle. The apparatus can be not only utilized on normal manual tricycles, but also utilized on normal bicycles, waterborne yachts, waterborne bicycles, and manual grinders. The utility model has low manufacture cost, and is suitable for small machine enterprises to put into production.

Description

Manual tricycle speed-raising work-saving device

Technical field:

The utility model is to belong to the mechanical gear transmission device.

Background technology:

Manual tricycle is to use one of extremely wide transport facility in people's daily life, it is to utilize manpower, pass through foot pedal, drive big chain plate and drag flywheel by chain again, car is advanced, the transmitting ratio of this moment decides with chain drum and flywheel, and the speed speed of driving is decided by manpower fully.If meet vehicle-mounted heavier or when being on the up grade, although the rider makes sufficient whole body strength, also difficulty is accelerated the speed of a motor vehicle, so need improvement.

Summary of the invention:

The purpose of this utility model, provide a kind of utilize that lever principle and gear make can the laborsaving device that can accelerate road speed again.

The technical solution of the utility model is as shown in Figure 1: with bolt of rear end plate 14,15 bonded assembly adapter plate 1A, there is big gear wheel 2 to be fixed on the main shaft 3 in the middle of the 1B, main shaft 3 two ends are by adapter plate 1A, ball bearing of main shaft 4 on the 1B inboard supports, adapter plate 1A is stretched out at main shaft 3 two ends, the 1B partial fixing has bent axle 7, two bent axles 7 are fixing with 180 degree symmetries on main shaft 3 two ends, the other end of bent axle 7 is connected with an end of chain bar 8, the other end of connecting rod 8 is the holes with pedal stroke 9 bending parts, connect with little axle 16, one end of pedal stroke 9 is to be positioned on the fulcrum shaft 10, the other end is equipped with tread plate, miniature gears 5 cooperates with big gear wheel 2, miniature gears 5 is fixed on the axle 6, and axle 6 two ends are by being fixed on adapter plate 1A, the ball bearing of main shaft 4 of 1B inboard supports, and an end of axle 6 stretches out adapter plate 1A part, be fixed with chain drum 11, chain drum 11 usefulness chains 12 are connected with flywheel.Knock hole 13 is arranged on adapter plate 1A, the 1B, be positioned on the former chain drum spindle hole of manual tricycle, make installing and locating and use.Whole device is secured in the tricycle frame with bolt of rear end plate 14.

Description of drawings:

Fig. 1, manual tricycle speed-raising work-saving device structural representation.

Wherein: 1A, 1B: adapter plate; 2, big gear wheel; 3, main shaft; 4, ball bearing of main shaft; 5, miniature gears; 6, axle; 7, bent axle; 8, chain bar; 9, pedal stroke; 10, fulcrum shaft; 11, chain drum; 12, chain; 13, knock hole; 14, bolt of rear end plate; 15, bolt of rear end plate; 16, little axle.

The specific embodiment:

Big gear wheel 2 of the present utility model and miniature gears 5 diameters are than about 2: 1, and like this, when big gear wheel 2 is rotated a circle, it is many that miniature gears 5 promptly rotates 2 circles, and it is many to make chain drum 11 also just rotate 2 circles, has reached the purpose that improves three-wheel vehicle speed.

Pedal stroke 9 bending parts of the present utility model are into 140 and spend to the angle between 150 degree, with 144 degree angles is the best, pedal stroke 9 about 40 centimeter length, and from fulcrum shaft 10 holes to little axle 16 holes about 10 centimetres, like this according to lever principle, can reach laborsaving function, and the tread plate path of motion of pedal stroke 9 is that rider left and right sides bipod is stepped on up and down by turns, and is different fully with the stretcher of common three-wheel vehicle circular movement, the people of pedaling this three-wheel vehicle can feel very easily laborsaving, and speed also can improve.

The utility model can make three-wheel vehicle be pumped into semi-lying type, and the operator only needs the left and right sides castor to change to step on, and car can advance fast, is fit to the elderly and uses.

The utility model can be installed on ordinary bicycle or pleasure-boat waterborne and the water cycle, and is more laborsaving than existing, safer.

The utility model can be used as propulsion source, is mounted to uses such as sharpner.

The utility model manufacturing is simple, and cost is low, and suitable common mechanical enterprise goes into operation.
