Title:
MULTIPLE-TRUCKLE SYNCHRONIZATION CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/179330
Kind Code:
A1
Abstract:
A multiple-truckle synchronization control system (100). The multiple-truckle synchronization control system (100) comprises a pedal component (1), a conversion-driving component (2) and a plurality of truckle components (3). Each truckle component (3) has a wheel body (301), a brake control element (301a) and a brake element; the brake control element (301a) is associated with the brake element to drive the movement of the brake element to brake the wheel body or release brake to the wheel body. The pedal component (3) has a brake pedal (103) and a restoration pedal (110); the brake pedal (103) and the restoration pedal (110) are connected by means of a swing arm (108) such that the relative positions of the brake pedal (103) and the restoration pedal (110) are always in a crossed state. The conversion-driving component (2) has a gear transmission mechanism, a joint lever (104) and a motion convention mechanism; one of the brake pedal (103) and the restoration pedal (110) is rotationally fit to the joint lever (104) via the gear transmission mechanism. The other of the brake pedal (103) and the restoration pedal (110) is connected to the joint lever (104) and can rotationally move relative to the joint lever (104). The joint lever (104) is connected to the motion convention mechanism. The motion convention mechanism is further connected to the brake control element (301a) and is used to convert the rotational motion of the joint lever (104) into a rectilinear motion of the brake control element (301a). The multiple-truckle synchronization control system (100) is easy to operate and is reliable.
