Title:
HYDRAULIC TIME DIFFERENCE-BASED BRAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/023471
Kind Code:
A1
Abstract:
A hydraulic time difference-based braking device, at least comprising: a drive mechanism (1) provided with a first drive rod (10) and a second drive rod (11), the first drive rod (10) and second drive rod (11) being partially inserted into a first chamber (21) and a second chamber (22) in a housing (2). The first drive rod (10) and second drive rod (11) are connected to a braking drive component (14). The braking drive component (14) drives the first drive rod (10) in a real-time manner and enables a first piston (30) of a first pump mechanism (3) to generate a displacement to output a first braking force to a rear-wheel brake (50). Within a time difference to the first piston (30) of the first pump mechanism (3) reaching a predetermined displacement distance, the second drive rod (11) joins and is driven simultaneously to drive a second piston (40) of a second pump mechanism (4) to produce a displacement to output a second braking force to a front wheel brake (51). In this way, for one braking operation of a rider or a driver, the present invention provides a first braking force and a second braking force having a time difference when generated by the first pump mechanism (3) and the second pump mechanism (4), such that braking actions of the rear wheel brake (50) and the front wheel brake (51) have a time difference, and afterwards enables the second braking force generated by the second pump mechanism (4) to be larger than the first braking force generated by the first pump mechanism (3) to increase a braking force for the front wheel brake (51), thus improving braking performance of a vehicle, and safety of the hydraulic time difference-based braking device.
