non-friction brake

Abstract

The invention discloses a non-friction type brake which comprises a moving part, a braking part and a non-friction type braking mechanism. The moving part and the braking part are arranged together coaxially in a sleeved mode and are matched in a rotating mode. Wheel teeth are arranged on the rotating matching face of the braking part. The non-friction type braking mechanism comprises a floating block which is arranged on the rotating matching face of the moving part in a floating mode in the radial direction and is in meshing transmission with the wheel teeth. The tangential direction angle of the action points of the floating block and the wheel teeth is continuously changeable. The non-friction type braking mechanism is of a transmission structure in which the floating block and the wheel teeth are matched, meanwhile, the tangential direction angle of the action points of the floating block and the wheel teeth is continuously changeable in a certain range, continuously-changeable joining force is generated, when the tangential direction angle is large, equal-torque output can be achieved, torque transmission capacity is high, vehicle braking distance is shortened, emergency braking performance is improved, meanwhile, the floating block and the wheel teeth are matched in a non-friction mode, the problem that due to part abrasion, maintaining is frequent, and service life is short can be avoided, and operation cost is lowered.

Description

technical field [0001] The invention relates to a brake, in particular to a non-friction brake. Background technique [0002] At present, most of the brakes used in vehicles adopt friction structure, and the brakes are performed through the friction between the moving part installed on the wheel and the braking part installed on the body or frame. Generally, the brakes need to be frequently activated during the driving process of the vehicle. To achieve effective control of the vehicle, and with the gradual increase in the number of vehicles, the road traffic is getting worse and worse, and the operating frequency of the brake is increased, resulting in serious friction between the moving part and the braking part. , maintenance is frequent, and the replacement and installation of components is difficult, the operating cost is high, and the service life is short. [0003] Therefore, in order to solve the above problems, a non-friction brake is needed to avoid the problems o...

[0002] At present, most of the brakes used in vehicles adopt friction structure, and the brakes are performed through the friction between the moving part installed on the wheel and the braking part installed on the body or frame. Generally, the brakes need to be frequently activated during the driving process of the vehicle. To achieve effective control of the vehicle, and with the gradual increase in the number of vehicles, the road traffic is getting worse and worse, and the operating frequency of the brake is increased, resulting in serious friction between the moving part and the braking part. , frequent maintenance, and difficult replacement and installation of parts, high operating costs and short service life

[0003] Therefore, in order to solve the above problems, a non-friction brake is needed to avoid the problems of frequent maintenance and short life due to component wear, and reduce operating costs.
