Abstract
The utility model relates to a driving mechanism of a running tool with driving force of pedal, comprising a front carrier wheel, a centre shaft, right and left cranks, an extension bar of crank, right and left constant pitches, right and left carrier gears and right and left satellite gears. The right and left carrier gears and the right and left satellite gears are arranged on the right and left cranks. The stationary gear has identical teeth number and mode number with the satellite gear, and the extension bar of crank is fixedly connected with a shaft of the stationary gear. The utility model increases the length of arm of force performing work without the increased up-down and right-left motion amplitude of the inferior extremity of human body, declining the ride intensity via the full utilization of the lever principle, and thus the utility model is generally suitable for a running tool with driving force of pedal.
Description
It is the driver train of the instrument that travels of propulsive effort that the utility model relates to the foot-operated masterpiece of a kind of usefulness.
The driver train of common bicycle is made of preceding sprocket wheel, axis and left and right sides crank, when riding, crank is made circular movement, crank length increases, lower limb about, about motion amplitude increase in proportion, the increase of crank length that main is is subjected to the restriction of itself and ground distance and human body lower limbs physiological structure, thereby can not effectively utilize lever principle to reduce the intensity of riding.
The purpose of this utility model is to provide a kind of driver train that can effectively reduce the bicycle of the intensity of riding.
For achieving the above object, the utility model is by the following technical solutions: it comprises preceding sprocket wheel, axis and left and right sides crank, it is characterized in that it also comprises crank lengthening bar and coaxial with axis, captive joint with vehicle frame, be located at the left and right sides fixed gear of left and right sides crank and axis coupling end side, the other end at left and right sides crank is provided with satellite gear, the axle of satellite gear is rotationally connected with left and right sides crank and captives joint with the crank lengthening bar, the identical modulus with the satellite gear number of teeth of described fixed gear is identical, also is provided with the carrier gear that cooperates with fixed gear and satellite gear on the crank of the left and right sides.
The utility model also can adopt following further technical scheme: it is provided with the preceding load-carrying element and the back load-carrying element of captiveing joint with vehicle frame, and the pinion stand of left and right sides fixed gear is enclosed within the axis outside, and captives joint with the back load-carrying element with preceding load-carrying element.
Owing to adopted above technical scheme, during assembling, the crank lengthening bar is arranged to parallel to the ground, and when be in acting when regional crank lengthening bar and crank be extended configuration; When riding, although crank is still made circular movement, but because fixed gear, cooperatively interacting of satellite gear and carrier gear, the parallel all the time and ground of crank lengthening bar, the least significant end of crank lengthening bar and most significant end are identical with the least significant end and the most significant end of crank, and be with respect to crank and add long status at the regional crank lengthening bar of acting, be folded state in the zone of not doing work, neither increase human body lower limbs about, about motion amplitude, the length of the arm of force when having increased acting again, make full use of lever principle and reduce the intensity of riding, can be applicable to generally that with foot-operated masterpiece be the instrument that travels of propulsive effort.
The utility model will be further described below in conjunction with drawings and Examples.
Side schematic view when Fig. 1 is installed on the bicycle for the utility model.
Birds-eye view when Fig. 2 is installed on the bicycle for the utility model.
Present embodiment is the specific embodiment that the utility model is applied to bicycle.
With reference to accompanying drawing.The utility model comprises preceding sprocket wheel 1, axis 2 and left and right sides crank 3,4, the utility model also comprises with axis 2 coaxial, captive joint with vehicle frame, be located at left and right sides crank 3,4 with the left and right sides fixed gear 5 of axis 2 coupling end inboards, 6, left and right sides fixed gear 5,6 can not rotate, at left and right sides crank 3,4 the other end is provided with satellite gear 7,8, also be provided with the carrier gear 9 that cooperates with fixed gear 5 and satellite gear 7 on the crank 3 of a left side, be provided with the carrier gear 10 of identical function on the right crank equally, carrier gear 9,10 axle 17,18 are located at left and right sides crank 3, on 4, carrier gear 9,10 can be around axle 17,18 rotate, the tooth interlock of its tooth and fixed gear that matches and satellite gear, satellite gear 7,8 axle 11,12 pass left and right sides crank 3,4 and with crank lengthening bar 13,14 captive joints, axle 11,12 can be with respect to left and right sides crank 3,4 rotate, crank lengthening bar 13,14 the other end and pedal 15,16 connect fixed gear 5 and satellite gear 7, fixed gear 6 is identical with the identical modulus of satellite gear 8 numbers of teeth.
The mode of left and right sides fixed gear 5,6 captiveing joint with vehicle frame can realize by the following method, load-carrying element 19 and back load-carrying element 20 before it comprises, preceding load-carrying element 19 is captiveed joint with standpipe 22 with the following pipe 21 of vehicle frame respectively with back load-carrying element 20, the pinion stand 23,24 of fixed gear 5,6 is enclosed within axis 2 outsides, and captives joint with back load-carrying element 20 with preceding load-carrying element 19.
During installation, be arranged to crank lengthening bar 13,14 parallel to the ground, and when be in when zone acting crank lengthening bar 13,14 and crank 3,4 be extended configuration, fixed gear 5 and satellite gear 7, fixed gear 6 are identical with the identical modulus of satellite gear 8 numbers of teeth, when riding, carrier gear 9,10 turns over some angles with respect to fixed gear 5,6, fixed gear 5,6 reversing senses turn over equal angular, crank lengthening bar 13,14 parallel all the time and ground, and be with respect to crank 3,4 in acting zone and add long status, be folded state in the zone of not doing work.
