The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprises the filling pump (4) that is fixed in the operating case (12), one end of filling pump (4) is connected with U type push rod (3), one end of the U type push rod (3) of filling pump (4) is connected with Parking stretcher (13), the fuel feed hole (7) of filling pump (4) is connected with fuel tank (9) by hydraulic oil pipe (10), oil outlet (8) is connected to an end of distributing box (14) by hydraulic oil pipe (10.1), and the other end of distributing box (14) is by hydraulic oil pipe (10.2) respectively in the fuel feed hole that is connected to damper brake (15) (16) of symmetry; Electrohydraulic push rod (1) is connected an end of filling pump (4) by U type gib (2) kink, and the connection box of Electrohydraulic push rod (1) is connected with contact switch (6) by power lead (5), and the other end of contact switch (6) is connected with external source (5.2).Described Electrohydraulic push rod (1) and filling pump (4) are fixedly mounted in the operating case (12) by bolt (11), and retracing spring (21) is housed in the Electrohydraulic push rod (1); Torsion spring (19) is housed on the described stretcher (13).
Principle of work of the present utility model is as follows:
When the driving walking needs glancing impact, press the knob of contact switch (6), bring into operation after Electrohydraulic push rod (1) energising simultaneously, the push rod (20) of Electrohydraulic push rod (1) promotes U type push rod (3) ahead running of filling pump (4), at this moment, high hydraulic brake fluid in the filling pump (4) is compressed to respectively in the oil cylinder (18) of damper brake (15) by hydraulic oil pipe (10) and distributing box (14) under the pressure of piston, damper brake (15) promotes brake facing (22) in the clamp both sides of brake disc (17) is produced pressure, the effect of reach decelerations, braking under the effect of oil pressure.Under the situation that integral body has a power failure, can brake with foot-operated, because the U type push rod (3) of Electrohydraulic push rod (1) and filling pump (4) is connected by U type gib (2) kink, so when pedal brake was used in the integral body power failure, Electrohydraulic push rod (1) can not worked simultaneously.
Unclamp the knob of contact switch (6), oil cylinder (18) the beginning release of damper brake (15), the piston in the oil cylinder (18) is by the specific device self-return, and brake facing (22) reduces simultaneously, and this moment, driving can normally move.
When unclamping the knob of contact switch (6), push rod (20) self-return under the effect of retracing spring (21) of Electrohydraulic push rod (1), at this moment the stretcher (13) on the U type push rod (3) of filling pump (4) can make the U type push rod (3) of filling pump (4) and the synchronous return of push rod (20) of Electrohydraulic push rod (1) by the effect of torsion spring (19).
