Abstract
The utility model relates to a foot-typed automatic boosting device for rickshaws, which is particularly suitable for installing on vehicles such as bicycles, manpower tricycles, etc. The utility model is provided with a torsional spring on a vehicular central shaft, and the torsional spring can store energy by stepping on the pedal and by the vibratory movement produced by the vehicle seat, thereby, driving the vehicle to move forward. The utility model has the advantages of amenity and labour saving when used. The utility model is much more superior if used in mountain area and hilly ground.
Description
The utility model relates to the driving device technical field of rickshaw, is particularly suitable for using on bicycle.
Bicycle is a kind of important traffic, transportation means.Thereby existing bicycle and other pedal type manual cars are directly to drive chain and rotate to drive car and advance by stepping step, and not only effort is big in use, and the speed of a motor vehicle is slow.Although people have done many-sided improvement on transmission device, all fail to solve can improve the speed of a motor vehicle again can the labour-saving problem, in addition because the poor flexibility of its vehicle seat uses comfortable inadequately.
The purpose of this utility model is a kind of in use not only laborsaving but also comfortable pedal type manual car motor-driven assistor of design.
A kind of embodiment of the present utility model comprises axis, chain wheel and car leg are installed on it, it is characterized in that on the axis that chain wheel one end is installed, installing the drive sleeve that two ends all have ratchet, chain wheel is installed on this drive sleeve, be connected with a spring case of captiveing joint on the drive sleeve with chain wheel, torsion spring is installed in it, and the inside and outside two ends of this torsion spring are individually fixed on drive sleeve and the spring case; Be equipped with on the axis and make the sour jujube cover that drive sleeve can only unidirectional rotation; Car leg near drive sleeve is provided with the ratchet that drive sleeve is rotated.
Another embodiment of the present utility model comprises vehicle frame, axis and vehicle seat are installed on it, chain wheel and car leg are installed on the axis, it is characterized in that on the axis that chain wheel one end is installed, installing the drive sleeve that two ends all have ratchet, chain wheel is installed on this drive sleeve, be connected with a spring case of captiveing joint with chain wheel on the drive sleeve, torsion spring is installed in it, the inside and outside two ends of this torsion spring are individually fixed on drive sleeve and the spring case; Be equipped with on the axis and make the sour jujube cover that drive sleeve can only unidirectional rotation, near being connected with the ratchet that drive sleeve is rotated on the car leg of drive sleeve; The one sour jujube circle that drive sleeve is rotated is installed on the drive sleeve, is provided with free-wheel clutch between the inner ring face of this sour jujube circle and the drive sleeve, be connected with pole between sour jujube circle and the vehicle seat, this pole is equipped with spring at the end near vehicle seat.
The utility model is particularly suitable for being installed on the transport facilitys such as bicycle, manual tricycle and uses.In the use, the uneven power that people's double-legged pedal-type bicycle leg produces when rotating, can and drive car by the torsion spring homogenize advances, and the power that the fluctuation up and down of vehicle seat produces also can make the torsion spring stored energy, but thereby autoamtic boosting, acceleration in using, and the elasticity of vehicle seat is strong, and is more comfortable during use.If in the mountain area, the Qiu Ling area uses, and more can embody preceence of the present utility model.
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the A-A cutaway view of Fig. 1; Fig. 3 is the structural representation of the utility model when being installed on the bicycle.
Embodiment 1, with reference to accompanying drawing, the utility model is equipped with axis (4) on vehicle frame, chain wheel (11) and car leg (2) are installed on the axis (4), go up the drive sleeve (5) that installation one two ends all have ratchet at the axis (4) that chain wheel (11) one ends are installed, chain wheel (11) is installed on this drive sleeve (5), go up near chain wheel (11) installation one spring case (8) in this drive sleeve (5), this spring case (8) is captiveed joint with chain wheel (11), torsion spring (12) is installed in the spring case (8), and the inner (9) of this torsion spring (12) and outer end (10) are separately fixed on drive sleeve (5) and the spring case (8).Car leg (2) is installed in the two ends of axis (4), and wherein the car leg (2) near drive sleeve (5) is provided with ratchet (3), and the ratchet engagement on this ratchet (3) and the drive sleeve (5) can make drive sleeve (5) rotate.The other end of axis (4) is installed a sour jujube cover (15), which is provided with ratchet (14), and the ratchet engagement of this ratchet (14) and drive sleeve (5) other end is so that drive sleeve (5) can only unidirectional rotation.
The utility model in use, step step (1) and can drive drive sleeve (5) rotation, vehicle seat (19) is owing to the power that vibration produces is passed through pole (13); rocking arm (7) also drives drive sleeve (5) and rotates; thus make torsion spring (12) stored energy; because drive sleeve (5) can only be rotated by working direction; thereby torsion spring (12) can advance by the rotating drive car of chain wheel (11) when releasing energy; thus make when using bicycle and other pedal type manual cars; can reach automatic vibration reduction; the purpose of power-assisted and acceleration, not only comfortable but also laborsaving.
