Transmission device of front and rear wheel 360-degree steering bicycle

Abstract

The invention belongs to the field of bicycle transmission devices, in particular to a transmission device of a front and rear wheel 360-degree steering bicycle. The transmission device comprises a chain wheel A, a chain wheel B, a chain wheel C, a chain wheel D, a bevel gear A, a bevel gear B, a bevel gear C and a bevel gear D, wherein the chain wheel A is driven to rotate under the drive of manpower and drives the chain wheel B to rotate by a chain B; the chain wheel B and the bevel gear A which is in rigid connection with the chain wheel B are rotated around a fixed shaft I; the bevel gear B is meshed with the bevel gear A; the bevel gear B and the bevel gear C which is fixedly connected with the bevel gear B are rotated around a fixed shaft II; the bevel gear D is meshed with the bevel gear C; the bevel gear D and the chain wheel C which is in rigid connection with the bevel gear D are rotated around a fixed shaft III; the chain wheel C drives the chain wheel D to rotate by a chain A, so that wheels are driven to rotate. According to the transmission device, the front and rear wheels are both allowed to control the steering, the translation and the sudden turning motion of the bicycle are realized, and the bicycle can turn around in a limited space range, changes the bicycle head direction in a narrow channel and rapidly reverses in a short distance.

Description

technical field [0001] The invention belongs to the field of bicycle transmission devices, in particular to a transmission device for bicycles with 360° front and rear wheels. Background technique [0002] In daily life, bicycles appear more as a means of transportation, and generally the rear wheels are non-steerable. There are three main types of bicycles on the market today: [0003] 1 Highway racing car: a car specially designed for racing on the road. The frame has a beautiful design, with a downturn handle design to reduce wind resistance, thinner low-resistance tires, and the wheel diameter is larger than that of ordinary cars. All mountain-climbing off-road vehicles are large, and they can move forward easily without too much effort. The frame material is made of ultra-lightweight materials. However, all parts of the body are relatively hard, the handling is not very good, the wheels are large and the acceleration is slow, and it cannot carry people. [0004] 2 Po...

Problems solved by technology

[0008] The invention has a mechanical structure and solves the following problems: ①The traditional chain transmission cannot control the steering of the front and rear wheels, and this transmission device can solve the unexpected problems that may occur when the bicycle changes lanes too quickly; The turning radius is reduced, and sharp turns can be realized in large-angle corners, which solves the problem of insufficient deceleration of traditional chain-driven bicycles when the turning radius is too large; The problem of inability to turn quickly in small cases; ④ This transmission device is based on the cooperation of gears and chains, which can solve the problem that traditional chain-driven bicycles cannot change the front of the bike in narrow passages and cannot reverse quickly in short distances in emergency situations
