Described fix shaft and potential device are installed in the hinged place of described pedal and main brake valve, and fix shaft is connected with potential device, and the junction of fix shaft and potential device is provided with a shifting fork mechanism.
Be provided with the push rod with described pedal linkage in the described main brake valve, the push rod outside is provided with center, and the outside of center is provided with fix shaft and piston, studs with scroll wheel on the described piston, and the below of scroll wheel is provided with rocker shaft, and rocker shaft is connected with described potential device.
Described potential device connects terminals, is respectively equipped with power input mouth, pedal position signal port, grounding ports and two switch wire connection ports on the described terminals.
Compared with prior art, the utlity model has following beneficial effect:
1, installs variable potentiometer additional, utilized pedal to depress to rotate with the axle of the potential device that is dynamically connected, made potential device send different variable signals, realized recovery and the braking of energy.Energy reclaims large, effective, greatly prolongation travelled distance or the time of degree.
2, in the process of normally travelling, effectively reduce or use hardly mechanical braking, in the service life of all elements of prolonged mechanical braking, in service life that especially can the prolonged mechanical drg, namely reduce the wearing and tearing of brake facing, brake drum or brake disc.
3, the deceleration under non-emergent braking is to brake without gas fully, and moving velocity can slowly be fallen, and the traveling comfort of taking is improved greatly.
4, main brake valve adopts the profile of conventional main valve, and commonality is good, reduces cost, and in-use performance is reliable, and long service life can adapt to more clients' functional need.
