Description

Recumbent bicycle

(1) technical field:

The utility model relates to a kind of vehicle, the recumbent bicycle of especially a kind of traveling comfort, good stability.

(2) background technology:

Health all was vertical regular sitting posture when present two-wheeled or tricycle were ridden, and is uncomfortable, and seat designs above pedal and head sprocket, effort, fatiguability when riding, and poor stability.It with regard to the present disclosed patent No. 92235777.3 recumbent bicycle, it is that pedal and head sprocket are designed at the front end that has three-wheel vehicle now, aft end face at seat has added a headrest and backrest, but seat still designs above front-wheel, center of gravity is high and more concentrated, still relatively requires great effort when riding, and headrest and backrest are unsettled because of back half, poor stability, traveling comfort are not remarkable.

(3) utility model content:

The purpose of this utility model is exactly for the public provides that a kind of center of gravity is low, traveling comfort, stability, safety recumbent bicycle preferably all.

This novel lying type bicycle comprises frame, be fitted in the wheel on the frame, sprocket wheel, the pad of lying, brake, directional controller and change-speed box, front end in the housiung separator centre is provided with the head sprocket support, head sprocket is fitted in the front end of head sprocket support, both sides are fitted with crank and pedal, three of wheels, wherein two wheels are fitted in the front end both sides of frame respectively, another is fitted on the follower head, different is, the wheel shaft of front-wheel is the wheelchair wheel shaft, two wheelchair wheel shafts are connected with the front axle bracket of housiung separator two ends respectively, a side is provided with the transmission guide wheel below the frame between corresponding two front-wheels of head sprocket, above the frame between two front-wheels and the trailing wheel, be fitted with the pad of lying that is skewed, lie the pad back and the trailing wheel frame between be provided with adjustable supporter, brake, directional controller is fitted on the frame, brake gear is a band-type brake, be fitted on the wheel shaft of two front-wheels, brake, the direction control handle is positioned at the pad both sides of lying, change-speed box is centrifugal change-speed box voluntarily, be fitted on the transmission shaft of trailing wheel head sprocket, driving chain wheel and the change-speed box that is fitted on the drive shaft of rear wheel link with chain.

On same contour plane, center of gravity is low, when the cyclist adopts tap pedal basically for the utility model pedal and seat, people's health can be as Reclining chairpostures at ordinary times, used power can directly be delivered on the backrest at seat by human body back, and also just additionally laborsaving when riding, traveling comfort is good; Brake gear adopts band-type brake, and brake price ratio and safety are all better; Change-speed box has been selected centrifugal change-speed box voluntarily for use, because this change-speed box is to adopt centrifugal and lever principle manufactures and designs and forms, its maximum characteristics are that the cyclist changes and automatic gear-shifting along with riding speed in the process of riding, relatively be fit to people's rule of riding normally, and can be according to the hobby of oneself, arbitrarily adjustment, random speed change have been simplified speed change system, have improved reliability and stability.This car is specially adapted to long-term travel, outdoor exercises, can be used as the equipment special of outdoor exercises.

(4) description of drawings:

Fig. 1 is an integral structure front view of the present utility model;

Fig. 2 is an integral structure birds-eye view of the present utility model.

(5) specific embodiment:

(2) three of wheels of the present utility model, wherein two wheels (2a) be fitted in respectively housiung separator (1a) two ends front axle bracket (11) on the wheelchair wheel shaft on, another wheel (2b) is fitted in the follower head of frame (1), the wheel shaft of two front-wheels (2a) adopts later-model wheelchair wheel shaft, it is simple and convenient relatively to make assembling safeguard, cost of manufacture reduces, centre front end at housiung separator (1a) is provided with head sprocket support (1b), head sprocket support (1b) is an adjustable support, the length that can regulate the head sprocket support according to the length of cyclist's leg, when being ridden, the cyclist is in the position of the most comfortable, front end at head sprocket support (1b) is fitted with head sprocket (3), the both sides of head sprocket (3) are fitted with crank (4) and pedal (5) respectively, rear side is provided with transmission guide wheel (6) in the corresponding housiung separator of head sprocket (3) (1a) below, the pad (9) of lying is skewed frame (1) top that is fitted between two front-wheels (2a) and the trailing wheel (2b), lie and be provided with adjustable supporter (1c) between the back of pad (9) and the trailing wheel frame (1), can regulated at will the lie angle of inclination of pad, to reach the purpose of the most comfortable, the pad of lying can be made by holder part and back cushion, holder part plays a supportive role, back cushion can use the screen cloth with high strength of high-intensity oxford and good permeability or other high-intensity textiless to make, be sleeved on the holder part outside, back cushion can remove cleaning; Brake, directional controller (7,8) be fitted on the frame (1) between two front-wheels (2a), brake gear (7) is a band-type brake, be fitted on the wheelchair wheel shaft of two front-wheels, band-type brake is better than braking quality with at present external pincers lock, with external popular butterfly lock than sound of laughing cheap, brake, direction control handle (8) is positioned at pad (9) both sides of lying, the physical slot that hand is in during with people's Seat-riding bicycle is corresponding, change-speed box (10) is centrifugal automatic transmission with hydraulic torque converter, be fitted on the transmission shaft of trailing wheel (2b), this change-speed box is to adopt up-to-date automatic transmission with hydraulic torque converter centrifugal and that lever principle is designed and manufactured into, its maximum characteristics are that the cyclist changes and automatic gear-shifting along with riding speed in the process of riding, relatively be fit to people's rule of riding normally, and can be according to the hobby of oneself, arbitrarily adjust, arbitrarily speed change has been simplified speed change system, has improved reliability and stability; Head sprocket (3), transmission guide wheel (6) and the change-speed box (10) that is fitted on the drive shaft of rear wheel link with chain (12).
