Abstract

The invention relates to a foot-pedal synchronous brake. A middle shaft is arranged in a shaft sleeve, and the front and rear ends of the middle shaft are connected with a chain wheel and the brake respectively. The brake is composed of a support plate, a driving gear, a transmission ring, a slide wheel, and a connecting plate. The support plate is connected with the rear end of the shaft sleeve via a center hole. The driving gear is connected with a rear shaft neck of the middle shaft. The long and circular transmission ring sleeves the driving gear which engages with a rack on an inner ring edge of the transmission ring. A left pulley and a right pulley are arranged on the two sides of the transmission ring respectively. The connecting plate is arranged on the outsides of the left and right pulleys and the transmission ring and is connected with the support plate via the rotating shafts of the left and right pulleys. The transmission ring can move up and down along a guide groove in the connecting plate. A braking line bypasses the upper end of the left pulley, the lower end of the transmission ring, and the upper end of the right pulley in sequence, and the left and right ends of the braking line are connected with the front and rear brakes of the bicycle. When the middle shaft drives the transmission ring to move downward along the guide groove via the driving gear, the transmission ring can simultaneously drive the front and rear brakes of the bicycle via the braking line.

Description

technical field [0001] The invention relates to a braking device for bicycles, in particular to a pedal synchronous brake capable of synchronously controlling the front and rear brakes by pedaling. Background technique [0002] At present, the front and rear brakes on the known bicycle are respectively controlled by the left and right brake handles on the steering handle through the brake wires, but because the brake handles and brake wires on the steering handle are easily involved with other bicycles, the traditional handbrake bicycle It is not convenient for centralized storage. Contents of the invention [0003] In order to overcome the disadvantage that the existing handbrake bicycles are not convenient for centralized storage, the invention provides a pedal synchronous brake, which can control the front and rear brakes on the bicycle by pedaling. The left and right brake handles and brake lines on the bicycle are convenient for centralized storage of bicycles. [0...
