Abstract:
A brake auxiliary device applied to a wheel of a vehicle, the brake auxiliary device comprising;a resilient mechanism having an upper support member mounted on a bottom surface of the vehicle at a position corresponding to the wheel, and a lower support member properly spaced apart from the upper support member and positioned above a shaft of the wheel; a transmission mechanism positioned between the upper and lower support members of the resilient mechanism in a manner that, the transmission mechanism rotatably abuts against the lower support member; and a drive mechanism connected to the bottom surface of the vehicle by a connecting member, and electrically coupled to the transmission mechanism for outputting power to operationally drive the transmission mechanism; wherein when the transmission mechanism is driven to rotate by power outputted from the drive mechanism, rotation of the transmission mechanism operates to induce displacement of the lower support member with respect to the upper support member of the resilient mechanism, and thus to generate up and down movement for the vehicle, so as to raise vertical upright pressure applied from the wheel of the vehicle to the ground, and to thereby increase friction between the wheel and the ground in favor of braking implementation.
