Abstract

The invention is applicable to the technical field of transmissions, and provides a fixing device for a bicycle transmission, comprising a main body bracket assembly and a guide plate assembly, with the main body bracket assembly comprising a main bracket, a first fixing shaft, a first fixing plate, a first fixing rod, a fixing buckle groove, a second fixing plate, a third fixing plate, a pull rod, a bolt, a spring, a screw and a nut, the first fixing shaft being rotatably connected with the main bracket. The first fixing plate is connected with a bicycle fixing frame by the first fixing plateconnected with the first fixing shaft. At that left side of the first fixing lever, the fixing buckle groove can be adjusted by rotation of the first fixing shaft. The adjustable fixing buckle grooveis connected with the bicycle fixing frame under the action of the rubber pad on the inner side wall, and finally the fixing groove is tightened and fixed by the nut on the first fixing shaft, whichgreatly increases the fixation between the transmission and the bicycle and improves the use safety.

Description

technical field [0001] The invention belongs to the technical field of transmissions, in particular to a fixing device for a bicycle transmission. Background technique [0002] The function of the bicycle transmission is to change the speed of the vehicle by changing the cooperation between the chain and the different front and rear size gear plates. The larger the rear chainring, the smaller the rear chainring, and the more laborious it is to pedal. The smaller the front chainring, the larger the rear chainring, the easier it is to pedal. According to the ability of different drivers, you can adjust the front and rear teeth The size of the disc adjusts the speed of the bicycle, or to deal with different road sections and road conditions. The number of teeth of the front chainring and the number of teeth of the rear chainring determine the strength when turning the pedals. The larger the front chainring, the smaller the rear chainring , When pedaling, the distance that the ...
