Abstract
The utility model relates to a bicycle medial axis power-assisted treading device, including a medial axis. The medial axis is arranged in a medial axis skin, in which bearings are arranged. One ends of legs for connecting pedals in two sets of pedal devices are respectively equipped with a perforation for perforating the medial axis. The utility model also includes a ratchet mechanism and a spring. The ratchet mechanism is arranged in the perforations, which are arranged on the ends of the legs for connecting pedals in two sets of pedal devices. The outer ring of the ratchet mechanism is fixed on the inner walls of the perforations. The inner ring is fixed to the middle axis. The direction of the ratchet mechanism is that when the pedals tread forward on the pedal devices, the medial axis is driven to rotate and the bicycle is driven to move forward. And the pedal devices move idly when rotating reversely and the medial axis does not move. The spring is arranged on the medial. A spring wire on one end is fixed on the pedal devices.

Description
Technical field
The utility model relates to a kind of bicycle middle shaft device, and a kind of bicycle middle shaft power-assisted foot pedal apparatus is provided.
Background technology
By the bicycle of foot pedal apparatus, need bicyclist's 360 degree complete cycles to rotate stretchers in the prior art as driving power.When riding, whenever treadle to rotate in the week and all will pass through the dead point, effort relatively especially against the wind or go up a slope when the inertia deficiency such as riding, often can't be passed through at dead center position.In order to address this problem, a lot of schemes have been proposed in the prior art, still, some scheme DeGrain is applied and other schemes have influence on it because of complex structure.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and providing a kind of can not run into the dead point when scrunching stretcher, and it is laborsaving to ride, and bicycle middle shaft power-assisted foot pedal apparatus simple in structure.
The utility model purpose can realize in the following way:
The bicycle middle shaft power-assisted foot pedal apparatus that the utility model provides, comprise axis, the axis skin, two cover foot-treadle devices, described axis places the axis intracutaneous, bearing is set therebetween, one end of the thigh of the connecting pin pedal in the two cover foot-treadle devices is respectively equipped with the perforation that a confession wears axis, it is characterized in that, also comprise ratchet device and spring, described ratchet device is arranged in the perforation that the end of thigh of the connecting pin pedal of foot-treadle device is provided with, its outer ring is fixed on the described perforation inwall, its inner ring is fixed on the axis, and the direction of this ratchet device is: described stretcher drives axis and rotates when the described foot-treadle device of forward pedaling, and the driving car advances, dally during the foot-treadle device backward rotation, axis is motionless; Described spring is worn and is arranged on the described axis, and one end spring silk is fixed on the foot-treadle device.
The bicycle middle shaft power-assisted foot pedal apparatus that the utility model provides is to use like this, its method that prior art installation axis is installed is installed on bicycle or the three-wheel vehicle stepping bicycle ground vehicle frame the samely, on axis as prior art hinge wheel is installed, establish on the hinge wheel chain with as prior art socket-connect with sprocket wheel on the bicycle rear, the forward rotation axis, promptly rotate, drive car and advance by sprocket wheel and chain drive rear axle.The other end spring silk of wood bicycle middle shaft power-assisted foot pedal apparatus upper spring is fixed on the relative fixed part of car, for example, can be fixed on the described axis skin, also can be fixed on the corresponding position of vehicle frame.
At first, one of the people foot-operated moving foot-treadle device on one side of riding makes thigh forward pedaling foot-treadle device in an angular range between two dead points up and down wherein, promote the axis forward rotation by ratchet, drive chain gearing driving car and advance, and spring described in this process is subjected to twisting force distortion accumulation elastic force.The people that rides then unclamps this batter device with pedal, the thigh of foot-treadle device counter-rotating under the effect of elastic force, owing to have ratchet device, the counter-rotating of foot-treadle device can not make axis reverse, but thigh idle running.Meanwhile, the people's that rides another pin is forward pedaling another stretcher in an angular range between two dead points up and down, drives the axis forward rotation, drives car and moves on.Back again, the another pin unclamps foot-treadle device, this cover foot-treadle device reversed turning under the effect of spring.Thus, two pin of people of riding alternately scrunch two stretchers in the angular range between two dead points up and down at both sides pedal thigh, and car can move ahead continuously.
In design, can also comprise a block in this bicycle middle shaft power-assisted foot pedal apparatus, as the upper limit of the counter-rotating that resets of thigh described in the foot-treadle device, this position is: with respect to the described thigh angle place that tilted before first dead center.
Angle of described bevelled is the 3-25 degree.Preferable angle can be 5 degree.
Described block is fixed on the described axis skin, also can be fixed on the connecting elements such as vehicle frame of bicycle.
The bicycle middle shaft power-assisted foot pedal apparatus that the utility model provides is by being provided with spring and ratchet in foot pedal apparatus, make the bicyclist not be used in and rotate foot-treadle device in the 360 degree scopes, can rotate by the continuous drive axis by the interior foot-treadle device that rotates of an angle one by one in office.Like this, can avoid two dead points up and down.Spring reset is set, and behind the stretcher forward rotation certain angle, as long as pin lifts a little, stretcher just resets thereupon, for foot-operated ready next time.Therefore, this foot pedal apparatus can be so that bicycle be avoided the dead point, and its structure is very simple, is easy to penetration and promotion.
Description of drawings
The main sectional structure scheme drawing of the bicycle middle shaft power-assisted foot pedal apparatus that Fig. 1 provides for the utility model;
Fig. 2 is the right TV structure scheme drawing of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, the bicycle middle shaft power-assisted foot pedal apparatus that the utility model provides comprises axis 1, axis skin 2, sprocket wheel 3, two cover foot-treadle devices 4, ratchet device 6 and spring 7, axis 1 places in the axis skin 2, bearing 5 is set therebetween, sprocket wheel 3 is fixed on the axis 1, one end of the thigh 41 of the connecting pin pedal 40 in the two cover foot-treadle devices 4 is respectively equipped with the perforation 411 that a confession wears axis 1, ratchet device 6 is arranged on the thigh of connecting pin pedal of foot-treadle device 4, its outer ring 61 is fixed on perforation 411 inwalls of thigh 41 1 ends by flush fit or riveted joint or welding or other affixed mechanical connection means, its inner ring 62 is fixed on the thread segment of the axis 1 in the perforation 411 that is arranged in thigh 41 by screw connection structure, thus, make foot-treadle device 4 by forward (as the A direction of Fig. 2) when scrunching, driving axis 1 rotates, and drive car and advance, then not driving axis 1 during backward rotation and rotate and foot-treadle device idle running, axis is motionless; Spring 7 is located on the axis 1, and one end spring silk 71 is fixed on the thigh 41 of foot-treadle device 4, and its other end spring silk 72 is fixed on the connecting element of car, for example on the axis skin 2.In actual use, also can be fixed on the vehicle frame, an end spring silk that is fixed on the connecting element at the spring that is provided with on the axis 1 on the sprocket wheel 3 one side axis can be fixed on the chain sheath body 8.
In design, can for example on the position on vehicle frame etc. a block be set at bicycle connecting elements such as axis skins, as the upper limit that foot-treadle device resets, this position is: with respect to the pedal thigh 41 of the foot-treadle device 4 angle a place that tilted before first dead center.This upper limit can be the 3-25 degree apart from the angle a of first dead center.Illustrative angle a is 5 degree in the present embodiment.
