Problems solved by technology

[0003] In the process of use, the vehicle needs to use the brake, that is, the brake device. Due to the unreasonable design of the existing brake device, its large volume takes up a lot of space, and the weight of the overall bicycle increases correspondingly after assembly, which does not meet the requirements of lightweight vehicles in today's society. requirements, not suitable for transportation and promotion

Abstract

The invention discloses a brake device. The brake device comprises a main shaft, a vehicle wheel core assembly and a vehicle frame assembly. The wheel core assembly is fixedly connected with one end of the main shaft, and the other end of the main shaft penetrates through the vehicle frame assembly to be connected with the output end of a power plant in a transmitting mode. A brake is arranged onthe vehicle frame assembly. The vehicle wheel core assembly is matched with wheels and driven by the main shaft to rotate to drive the wheels to rotate. The vehicle wheel core assembly is matched withthe brake, a gap is reserved between the brake and the vehicle wheel core assembly in a first state, so that the brake and the vehicle wheel core assembly do not make contact, and the brake is attached to the wheel core assembly to complete braking in a second state. According to the brake device, the wheels and a vehicle frame are reasonably integrated as a whole, the size of the brake device isreduced, the occupied space is reduced, the overall assembly weight is light, and the requirement of the lightening of the vehicle is met under the condition of achieving the braking effect.

Description

technical field [0001] The invention relates to the field of mechanical braking, in particular to a braking device. Background technique [0002] Bicycles can be used as an environmentally friendly means of transportation for transportation and travel; among them, the emergence of shared bicycles has brought great convenience to people's travel, and with the popularity of shared bicycles, more and more people use bicycles as fitness equipment. Ride for workouts or bike outings. [0003] In the process of use, the vehicle needs to use the brake, that is, the brake device. Due to the unreasonable design of the existing brake device, its large volume takes up a lot of space, and the weight of the overall bicycle increases correspondingly after assembly, which does not meet the requirements of lightweight vehicles in today's society. Requirements, not suitable for transportation and promotion. Contents of the invention [0004] The purpose of the application of the present i...
