Description

Chainless long arm pedal lever bicycle

Technical Field

The utility model relates to the technical field of bicycles, in particular to a chainless long-arm pedal lever bicycle.

Background

The bicycle in the current market is in pedal type chain wheel transmission, two pedals are vertically and fixedly distributed, and the two pedals are alternately treaded and circularly move around the chain wheel. Such designs are relatively simple and easy to operate, but tend to be relatively short due to the limited ground height of the foot bars, and therefore, to a relatively low power output. The rider can ride on the flat ground, and the rider feels hard when encountering a slope or a load.

In the figure: 1. a front wheel; 2. a front fork; 3. a handlebar; 4. a vehicle seat; 5. a rear fork; 6. a rear wheel; 7. a spring; 8. a right pedal; 9. left foot pedal; 10. a baffle plate; 11. a frame; 12. and a one-way bearing.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a no sprocket long arm pedal pole bicycle, includes frame 11, handlebar 3 and saddle 4 are installed respectively to the top at 11 both ends of frame, front fork 2 and back vent 5 are installed respectively to the bottom at 11 both ends of frame, front fork 2 is kept away from the one end of frame 11 and is installed front wheel 1, back vent 5 is kept away from the one end of frame 11 and is installed rear wheel 6, back vent 5 is all passed at the both ends of the axis of rotation of rear wheel 6, and the axis of rotation passes one-way bearing 12, two have been cup jointed on the axle wall of 5 one ends of back vent on the outer wall of one-way bearing 12 respectively fixedly connected with left pedal 9 and right pedal 8.

Equal fixedly connected with spring 7 on the lateral wall of back fork 5 both sides, and two spring 7 keeps away from the one end of back fork 5 respectively with adjacent left pedal 9 and right pedal 8 fixed connection, and spring 7's pulling force can make left pedal 9 and right pedal 8 can reset automatically after trampling.

The all fixedly connected with baffle 10 in both sides of frame 11 bottom, baffle 10 is located between front fork 2 and back fork 5, and baffle 10 can effectually prevent that the foot from trampling excessively and leading to the problem of left pedal 9 and right pedal 8 and ground contact when trampling left pedal 9 and right pedal 8.

Specifically, under the condition that the person of riding uses equal strength, in order to improve the output who tramples, the design of extension running-board arm of force has been adopted, and sprocket and chain have been saved, can effectually avoid the trouble that the in-process chain that rides drops and cause by the sprocket, shift the concentric position of axis of rotation on bicycle rear wheel 6 after the axle center of current pedal pole, the length of pedal pole is very for lengthening, one-way bearing 12 has been add in the bottom of pedal pole, and spring 7 has been add at the rear portion of pedal pole, one-way bearing 12 locks when running-board forward like this, the running-board motion drives the sprocket and rotates, the front end of running-board is equipped with baffle 10, prevent that the running-board from hitting the ground and restrict the running-board and advance. When the pedal on one side reaches the baffle 10, the pedal rod will be bounced upwards to return to the high position under the action of the spring 7 after the pedal force is released. Because the one-way bearing 12 is installed, there is no resistance and hindrance to the reverse movement. The pedal on the other side adopts the lagging movement, so that the pedal on the two sides can alternately move, the continuous and smooth movement of the rear wheel 6 of the bicycle is realized, and the bicycle is driven to move forwards. When the load is large or the gradient is large, the pedals on the two sides can be simultaneously stepped down, and the maximization of the output power is realized by concentrating the force.
