Description
Technical Field
The utility model relates to a body-building sports apparatus, in particular to a body-building bicycle with a central CVP stepless speed changer.
Background
The bicycle for body building is similar to a bicycle at ordinary times, but has much poorer functions and functions, is mainly used for indoor sports, overcomes all the defects of outdoor running, and can enable the whole body of a person to be exercised. At present, a bicycle for body building drives a flywheel by a belt through pedaling, the weight of the flywheel is fixed, the driving demand force is fixed, and one machine cannot adapt to different people. To this kind of problem patent number CN201920849785.8 disclose a multiple regulation formula spinning through the counter weight double-screw bolt increase and decrease counter weight of taking the cooperation installation, realize the degree of difficulty of trampling and adjust, satisfied user's variety requirement, though this kind of mode solves the problem of using the variety but need carry out the counter weight operation when using, it is not convenient very much to use.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problems, the defect is overcome, the bicycle with the CVP continuously variable transmission for body building is provided, the feedback of the bicycle can be conveniently adjusted, the body building requirements of different people are met, and good exercise experience is obtained.
The technical scheme is as follows: a body-building bicycle with a central CVP (continuously variable transmission) comprises a CVP planetary steel ball continuously variable transmission, a chain wheel, a pedal crank, a transmission chain, a speed regulation handle, a vertical rod, a cushion, a motion flywheel, a frame and a speed regulation device, and is characterized in that the input end of the CVP planetary steel ball continuously variable transmission is connected with the pedal crank, and the output end of the CVP planetary steel ball continuously variable transmission is connected with the chain wheel; the motion flywheel is provided with a flywheel chain wheel which is driven by a transmission chain and a chain wheel; the cushion is arranged on the frame and above the pedal crank, and the speed regulation handle regulates the speed of the CVP planetary steel ball stepless speed changer through the speed regulation device.
Furthermore, the exercise bicycle with the central CVP continuously variable transmission further comprises a speed sensor and a display control unit, wherein the speed sensor measures the rotating speed of the output end of the CVP planetary steel ball continuously variable transmission and transmits data to the display control unit through a data line.
Furthermore, an LED lamp is arranged on the bicycle display control unit for body building of the central CVP stepless speed changer.
Furthermore, the cushion is a lifting cushion, and the vertical rods are lifting vertical rods.
Further, the speed sensor is a hall rotating speed sensor.
When the bicycle for body building with the central CVP continuously variable transmission works, a user treads on a pedal to drive the input end of the CVP planetary steel ball continuously variable transmission to rotate, and the output end of the CVP planetary steel ball continuously variable transmission rotates to drive the chain wheel to rotate, so that the flywheel is finally driven to rotate. The flywheel has constant weight, and when needing to be adjusted, the speed regulating handle is rotated to control the CVP through the speed regulating device, so that the purpose of adjusting power is achieved. The speed sensor measures the rotating speed of the output end of the CVP planetary steel ball continuously variable transmission, speed data are transmitted to the display control unit, riding speed information can be seen, the LED lamp arranged on the display control unit can be brighter and brighter along with acceleration of the speed, and a user is stimulated to move.
The utility model discloses the principle: the CVP planetary steel ball stepless speed changer is applied to the bicycle for body building, is directly arranged at the pedal position, and is used for speed regulation through the speed regulation device, so that the same exercise bicycle can meet the exercise requirements of different crowds on different strengths, and meanwhile, the data such as the exercise speed and the like are monitored through the sensor.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the utility model discloses a be applied to CVP planet steel ball buncher for body-building bicycle, directly arrange in pedal department, realized need not to change or increase the regulation that different intensity of motion just can be realized to the counter weight flywheel, easy operation is convenient, tempers and experiences.
