Abstract
The invention provides a front three-wheel bicycle, which belongs to instead-of-walk transportation facility. China has entered into the old-age society. The elderly often take part in outdoor activities and exercises the legs, which greatly helps to keep healthy and prevent ageing. Riding a common bicycle can better exercise the legs, but is not suitable for the elderly. The novel seat type front three-wheel bicycle is safe, stable and fast, and is quite suitable for the elderly. The front part of the bicycle is provided with two small wheels, while the back part is provided with a large wheel; the height of a bicycle seat is the same as that of a chair often used in families, the large seat and a back rest are arranged among the three wheels, if a user rides the bicycle, the user can feel comfortable, stable and safe, and is also easy to ride the bicycle; when the bicycle turns, the bicycle body is automatically inclined inward to neutralize the centrifugal force, thereby avoiding the turn-over of the bicycle; and two balance springs have moderate elastic force, and can stabilize the riding direction of the bicycle, and the user only needs to lightly hold a handle bar to control the bicycle. In present cities, the living condition and the mentality of the elderly are good, and the elderly have high expectation on the health, so that the seat type front three-wheel bicycle specially designed for the elderly has stable and wide markets.
Description
Technical field:
The invention belongs to running vehicle.
Background technology:
Existing bicycle all is former and later two wheels, and the balance that can not keeping is a kinetic balance, then needs support when stopping, and rides usefulness so be not suitable for the elderly.Existing three-wheel vehicle is the load-carrying vehicle of back three-wheel, the vehicle body heaviness, and it is bigger than normal to exert oneself, and is not suitable for the elderly equally and rides usefulness.
Summary of the invention:
The objective of the invention is to develop a chair type, the front two-wheel turns to, the back single wheel drive, and automatic introversion is with the front three-wheeled bicycle of the safety labor-saving of counteracting centnifugal force when turning to.
Description of drawings:
Fig. 1 front elevation; Fig. 2 lateral plan; Fig. 3 birds-eye view.1 front-wheel among the figure, 2 trailing wheels, 3 is foot-operated, 4 seats, 5 backrests, 6 handlebars, 7 balance springs, 8 fronts wheel spindle, 9 preceding standpipes, 10 vehicle frames.
The specific embodiment:
The present invention is the new ideas vehicle that existing bicycle part is reconfigured.Wheel diameter 410mm～510mm before 1 wherein, two front-wheels are connected by 8 fronts wheel spindle, and front-wheel is with bearing replacement pearl pan, axletree diameter 16mm, an end is inserted in the bearing, and an end is inserted in the front wheel spindle sleeve pipe; 2 back wheel diameter 510mm～610mm are the standard bicycle rear of band flywheel; 3 foot-operated correct positions forwardly adopt small size axis and pedal external member, and are brisk laborsaving; 4 seats are very roomy, and 5 backrests are very comfortable, and seat and backrest are filled in and issued foam material exterior skin leather in all being; What be distributed in 8 front wheel spindle two ends is two 6 vertical handlebars, under the pulling force of 7 balance springs two front-wheel ride comfort under various road conditions is all fine freely; 8 fronts wheel spindle are the steel pipe of length 620mm, diameter 36mm, wall thickness 3mm, and the stage casing is inserted with the sleeve pipe that 150mm, two ends are inserted with 50mm, standpipe sleeve pipe before firmly welding in the middle of the front wheel spindle, this sleeve pipe be inserted in vehicle frame 9 before on the standpipes; 10 vehicle frame tubing firmly weld with drawing position and dimensional characteristic for the bicycle tubing of thickening; The front rake of 9 preceding standpipes was 7～9 degree when this front three-wheeled bicycle assembled.
More than welding, assembling etc. are ripe bicycle standard procedure and standardized parts, do not have technical barrier.
China has entered aged society.Can often go outdoor activities and do some leg exercises more the elderly for keeping fit, prevent that aging is highly profitable.Though ordinary bicycle is good leg exercise, is not suitable for the elderly.The chair type front three-wheeled bicycle safety of innovation, reliable brisk again is fit to the elderly very much.
This car front is two smaller wheels, and the back is a bigger wheel; The height at seat is the same with chair in the family, and roomy seat and backrest are sitting in top comfortablely, reliable have a sense of security again in the middle of three wheels; Leg lift gently just can step on foot-operated because drive wheel is single-wheel, thus trample ride also very brisk; The automatic introversion of vehicle body can not overturned to offset centnifugal force when turning to; Balance spring keeps the direction of car stable, and hand is not painstaking.
Chinese society is stable, economical plentiful, and old popular life state in city and phychology are all fine, and be very high to the expectation of health, and institute thinks that the directed design-calculated chair type of old friends front three-wheeled bicycle has stable and market broadness.
