Abstract
The invention discloses a novel mechanical braking device for the outer edge of a driving wheel. The turning point of an emergency braking pedal plate and a pedal plate in an original hydraulic braking device of a vehicle refers to the same point; a belt wheel (eccentric wheel) clutch is connected with an eccentric pull rod structure and a swing stem; a pull rod at the lower end of the emergency braking pedal plate is connected with a swing stem and a bull stick mechanism; the bull stick mechanism is connected to a motor vehicle transverse beam; and the other end of the bull stick mechanism is connected with an outer edge brake shoe which is coated by a rubber layer through a metal block and is arranged at the outer edge of the driving wheel. The torsional force of an engine and a friction force formed between the outer edge brake shoe and the ground to form a composite force, so that the driving wheel is prevented from sliding forward. Torsional force output to the driving wheel by the engine can be cut off by using a motor vehicle clutch, and rolling (emergency braking) of the driving wheel is prevented by using an original hydraulic (pneumatic) braking device, so that inertial sliding is prevented on the premise of turning a rolling state to a static state; and an 'internal intercepting and external blocking' measure is taken on the driving wheel together with the hydraulic (pneumatic) braking device, so that traffic accidents are prevented.
