Problems solved by technology

The traditional gear shifter is a multi-level variable speed adjustment. When the user toggles the gear shifter, he can feel the obvious stuttering, so he can know how many gears he has adjusted without visual judgment. However, the gear shifter is on the wire rope. During the transmission process, there will be precision errors due to friction, often causing the user to clearly dial up the 2nd gear, but the shift mechanism actually only raises the 1st gear.

Abstract

The invention provides a rear-mounted precise speed changing and gear shifting device based on line transmission. The device is characterized by comprising a finger shifting device arranged on a bicycle handle, a gear shifting mechanism arranged on a bicycle rear wheel, and a steel wire rope with one end connected with the finger shifting device and the other end connected with the gear shifting mechanism. The gear shifting mechanism comprises a gear shifting device connected with the steel wire rope and a transmission connected with the gear shifting device, and when a user pokes the finger poking device, the steel wire rope drives the gear shifting device located on the rear wheel so that the transmission connected with the gear shifting device is driven to shift and change the speed. The transmission distance of the steel wire rope between the gear shifting device and the gear shifting mechanism is shortened so that the gear shifting device is prevented from generating precision errors due to friction in the linear transmission process, and a larger fault-tolerant value is provided for the input of the gear shifting device under the condition that the gear shifting precision is not modified.

Description

【Technical field】 [0001] The invention relates to the technical field of bicycles, in particular to a rear-mounted precision gear shifting device based on wire transmission. 【Background technique】 [0002] The bicycle with gear position adjustment is a common means of transportation for people. By adjusting the gear position of the bicycle, the purpose of gear shifting is achieved. Existing bicycle shifters are usually arranged near the handlebars of the bicycle, and the user toggles the shifter with fingers to make the shift mechanism located at the rear wheel and connected to the shifter through a wire rope realize gear shifting. The traditional gear shifter is a multi-level variable speed adjustment. When the user toggles the gear shifter, he can feel the obvious stuttering, so that he can know the approximate number of gears he has adjusted without visual judgment. However, the gear shifter is on the wire rope. During the transmission process, there will be precision er...
