Abstract

The invention relates to a single person riding high-speed bicycle which is equivalent to a plurality of persons pedaling a long-force arm lever, and aims to solve the problem that when the conventional manpower bicycle wants to run at high speed, a rider needs to continuously pedal with violent force, so that the rider feels tired and is not easy. The structure is simple, the action is reliable, and the operation is easy. Particularly, the power is strong, people easily pedal at low frequency and step on the bicycle at high speed, and the bicycle is an ideal light traffic transportation tool which cannot be replaced.

Description

Single person riding high speed bicycle equivalent to multi-person pedaling long-arm lever control

The technical field is as follows:

the invention relates to a bicycle, in particular to a high-speed bicycle which is ridden by a single person and is operated by a long-strength arm lever.

Technical background:

at present, domestic and foreign manpower drive's bicycle, no matter conventional bicycle, still variable speed mountain bike, ubiquitous power supply (cyclist self physical output) latent energy utilization is low, it is narrow to promote the space, it wants high-speed the traveling to have restricted the bicycle, the people just must exert oneself incessantly step on the pedal in a hurry in succession, if long-distance riding, then people feel tired certainly, for this reason (Shandong dingtao Yuanlun) is repeatedly argued, several tests, the design is researched and developed people's light low frequency and is trampled from top to bottom, but the bicycle can be not less than forty kilometers per hour at the time speed under normal road conditions, a single riding is equivalent to many people trample long power arm pole simultaneously and is controlled high-speed bicycle.

The invention content is as follows:

the invention aims to overcome the defects in the prior art by a single person to ride a high-speed bicycle which is equivalent to a long-arm pedal lever operated by a plurality of people by pedaling the long-arm lever, and provides a dynamic support point which has a principle similar to that of ' carrying a load with unequal arm force by a person ' to carry a load on the load ' on the long-arm pedal lever, namely, the pedal of a conventional bicycle is replaced by a sleeved roller and is equivalent to that of ' picking the load on the shoulder ', and is actually an unequal arm lever of the long-arm pedal lever. The Z-shaped pulling rod on the auxiliary shaft acted by the normal force applying human foot and matched counterweight of non-heavy object is equivalent to the heavy object with unequal arms of a shoulder pole, and comprises a middle shaft on a main chain wheel of the bicycle and the auxiliary shaft synchronously linked with the middle shaft, and the long-arm pedal rod can only move up and down and slide laterally.

As optimization, opposite symmetrical L-shaped swing rods are assembled (actually fixedly assembled) at two ends of a middle shaft of the bicycle, a rotating sleeve and a roller at the front end of a connecting rod are sleeved outside the middle shaft, the inner side of the tail end of a long-arm pedal rod is constantly pressed on the roller, and the rear end of the long-arm pedal rod is sleeved and hinged at two ends of an auxiliary shaft and is assembled at the outer end of a Z-shaped pull rod.

For optimization, the two ends of the auxiliary shaft are oppositely arranged and symmetrical on the outer ends of the Z-shaped dead man, vertical small shafts are assembled, and a connecting rod rear end rotating sleeve and a long arm pedal rod rear end rotating sleeve are respectively sleeved on the small shafts from inside to outside. The design is suitable for forced transfer of the middle shaft of the bicycle, and the purpose that the middle shaft and the auxiliary shaft rotate synchronously and coordinately at the same frequency and the same angular speed is realized through the auxiliary shaft which is hinged and linked at the two ends of the connecting rod. Therefore, the bicycle can be smoothly treaded up and down in a circulating reciprocating manner by the cyclist, the bicycle can be continuously driven to move forward, and meanwhile, the proper up-and-down treading momentum of the legs of the cyclist is ensured.

As optimization, the two ends of the auxiliary shaft are provided with oppositely symmetrical Z-shaped pulling arms (actually fixedly arranged), so that the L-shaped swing arms at the two ends of the middle shaft and the Z-shaped pulling arms at the two ends of the auxiliary shaft are realized, the aim of collision is not generated in the respective circumferential motion around the shaft, and the linkage coordination of the two pedal levers with the upper long force arm and the lower long force arm alternately working is realized. The force is guided smoothly without affecting others.

The main chain wheel is fixedly arranged at one end of the middle shaft, two long-arm pedal rods are alternately and alternately operated through chain transmission to generate uninterrupted torque which is transmitted to an inner speed changer assembled in the center of a rear tire of the bicycle, and the design realizes the purposes that people easily step on the bicycle at low frequency and the bicycle can be manually adjusted to run.

By adopting the technical scheme, the forced middle shaft is hinged with the auxiliary shaft through the connecting rod, the purpose of rotation of the two shafts at the same frequency and the same angular speed is realized, two pedal rods with long force arms are sequentially ensured to be alternately treaded by small amplitude one above the other, and the energy source continuously provides the treading force of natural low-frequency people for the bicycle so that the bicycle advances at a high speed.

Description of the drawings:

as shown in fig. 1, the working principle of the single-person riding high-speed bicycle is equivalent to that a plurality of persons pedal long-arm levers to control the high-speed bicycle.

The specific implementation mode is as follows:

as shown in figure 1, a single person rides a high-speed bicycle which is equivalent to a plurality of persons pedaling a long-arm lever to control the inner side of one end of a middle shaft (1) of the high-speed bicycle, a main chain wheel (10) is fixedly arranged on the inner side of the middle shaft (1), L-shaped swing rods (11) are assembled at the two ends of the middle shaft (1), and a rotating sleeve (31) and a roller (13) at the front end of a connecting rod (3) are respectively sleeved at the outer ends of the swing rods (. The auxiliary shaft (2) is assembled on the frame in parallel with the middle shaft (1) and is tightly attached to the middle shaft (1). Two ends of the auxiliary shaft (2) are provided with a Z-shaped pulling arm rod (20), the outer end of the Z-shaped pulling arm rod (20) is provided with a vertical small shaft (21), the vertical small shaft (21) is sleeved with a connecting rod (3) rear end rotating sleeve (32) and a long arm pedal rod (4) rear end connecting body rotating sleeve (40) from inside to outside, the tail part of the long arm pedal rod (4) rear end is pressed on the roller (13), and the main chain wheel (10) is driven by a chain (5) to gnaw the inner speed changer (50) arranged in the center of the rear wheel of the bicycle.

Claims

1. A single person riding high speed bicycle is characterized in that a middle shaft of the bicycle is hinged with an auxiliary shaft through a connecting rod to implement synchronous co-frequency rotation coordination of two shafts, so that a low-frequency gentle downward pedaling force of a rider acts on the front end of the long arm, the rear end of a long arm pedal rod with unequal arm of force constantly presses on rollers (lever supporting points with different arm of force) arranged at two ends of the middle shaft of the bicycle, and an L-shaped swing rod assembly enables two vertically-moving pedal rods to alternately work in an alternating mode to convert the downward pedaling force of the rider into middle shaft rotation torque.

2. The single-person riding high-speed bicycle corresponding to multi-person pedaling of a long-arm lever according to claim 1 is characterized in that rollers are assembled at the outer ends of L-shaped swing rods at two ends of a middle shaft of the bicycle and Z-shaped pull rods are assembled at two ends of an auxiliary shaft synchronously coordinated with the middle shaft at the same angular speed, and the single-person riding high-speed bicycle is realized by respectively twisting the outer ends of the L-shaped swing rods at two ends of the middle shaft and the outer ends of the Z-shaped pull rods at two ends of the auxiliary shaft by using rotating sleeves at two ends of a connecting rod and assembling vertical small shafts.
