Abstract
The utility model relates to a single push rod electric hydraulic driving apparatus, which is mainly used for the driving device of a brake. A motor (22) is positioned beneath a hydraulic cylinder (8), and a hollow cavity is arranged on a motor shaft (21). A rotary shaft (20) is sheathed in the hollow cavity of the motor shaft and connected with an impeller wheel (14), a piston (13) and a push rod (3), and a torque gearing is arranged on the motor shaft and the rotary shaft. The hydraulic driving apparatus has the advantages of simple and artful structure, labour saving, material saving and obvious energy-saving effect, and the manufacture difficulty and the manufacture cost are greatly reduced.
Description
The utility model relates to a kind of single push rod electro hydraulicthruster, is mainly used in the drive unit of making break.
The basic structure of hydraulic push-rod brake comprises that drive unit is that electro hydraulicthruster and bag brake gear are the brake bracket two large divisions.Electro hydraulicthruster is general main to be made of motor, oil hydraulic cylinder, push rod, piston and impeller etc., and push rod is connected with piston; Utilize the high speed rotating of impeller to produce pressure reduction in oil hydraulic cylinder, press piston and push rod and move rapidly, push rod drives the lever system and the brake spring of brake bracket by the lever link.In the prior art, the break of various structures and model, particularly its hydraulic driver, ubiquity complex structure, and material consumption, worker consume greatly, and manufacture difficulty is big, cost height, and shortcomings such as energy consumption height, inconvenient maintenance.These problems are unresolved for a long time, caused most manufacturers and users' concern.
The purpose of this utility model provides a kind of new single push rod electro hydraulicthruster, and this pusher configuration is simple, and manufacture difficulty and cost reduce.
The purpose of model utility realizes by following mode.
Single push rod electro hydraulicthruster, structure comprises motor, oil hydraulic cylinder, push rod, piston and impeller, motor is positioned at the below of oil hydraulic cylinder, have cavity on the motor shaft, a rotating shaft is arranged, this rotating shaft is enclosed within the cavity of motor shaft, and motor shaft and rotating shaft are provided with torque transmission device, and rotating shaft is connected with impeller, piston and push rod.
Its working procedure is: after the pusher energising, motor shaft drives rotating shaft and the impeller high speed rotating that is connected with rotating shaft by torque transmission device, at this moment the fluid on piston in hydraulic cylinder top is under the impeller action of centrifugal force, be drawn onto the piston bottom, make the piston bottom form high pressure, promote piston and the rotating shaft that is connected with piston, impeller and push rod rising rapidly, the moving lever link of the last shipper pole of push rod moves, thereby promotes lever system and brake spring in the bag brake gear; After outage, the pusher push rod is forced under the brake spring tension force back-pressure of deadweight and bag brake gear, gets back to state of equilibrium.Such release and braking process per hour can be operated 1200 times.
Single push rod electro hydraulicthruster that the utility model provides, key is dexterously rotating shaft to be through in the cavity of motor shaft, thereby rotating shaft not only can be rotated the impeller high speed rotating with motor shaft, thereby and can move up and down and can guarantee moving up and down of impeller, piston and push rod.This pusher configuration is exquisite simple, saving of labor, material-saving, and manufacture difficulty and cost reduce significantly, and remarkable energy saving effect is arranged.This pusher is compared with existing like product, not only simple than baroque all kinds of single push rod pusher configuration, and also lack about 15 main parts in addition than better simply relatively pair of push rod series product of structure, and its every technical performance index is without any reducing or weakening.Because structural simplification, except manufacture difficulty reduction, saving of labor, material-saving, the used power of motor of same specification pusher also greatly reduces, as the Ed series product of former federal republic of germany EMG company and the series product such as single push rod MYT2, MYT3 of China, its 220N and 300N thrust, needing power of motor is 120W and 180W, and single push rod pusher described in the utility model, the thrust of its 180N and 250N, only needing power of motor is 25W and 40W.In addition, because the simplification of structure reduces the pusher rate of fault, easy to maintenance.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing is the structural representation of single push rod electro hydraulicthruster of providing according to the utility model, comprises lever link (1) among the figure, straight pin (2), push rod (3), inner protective tube (4), outer pillar (5), axle bush (6), refueling bolt (7), oil hydraulic cylinder (8), oil level bolt (9), straight pin (10), bearing (11), spacer sleeve (12), piston (13), impeller (14), square key (15), feather key (16), O RunddichtringO (17), reinforced seal (18), bearing (19), rotating shaft (20), motor shaft (21), micro motor (22), oil discharge screw (23), fitting seat (24).
As shown in drawings, motor (22) is positioned at the below of oil hydraulic cylinder (8), motor shaft has cavity on (21), a rotating shaft (20) is arranged, rotating shaft (20) is enclosed within the cavity of motor shaft, motor shaft and rotating shaft are provided with torque transmission device, and rotating shaft (20) is connected with impeller (14), piston (13) and push rod (3).
Torque transmission device in motor shaft and the rotating shaft (20) has three kinds.A kind of is the feather key (16) that is provided with on the motor shaft cavity inner wall and the featherway that matches with feather key in the rotating shaft; Another kind is spline on the motor shaft cavity inner wall and the spline that matches with spline on the push rod; The third is meant on the horizontal section of rotating shaft and motor shaft cavity the corner angle that cooperatively interact, and is square as sectional shape, regular hexagon etc.
As shown in the figure, be provided with bearing (11) between rotating shaft (20) and the piston (13), the lower end of push rod (3) is fixed on the bearing bracket of bearing (11) by pin (10), and its upper end connects lever link (1) by pin (2).The setting of bearing (11) can not rotated piston and push rod with the rotation of rotating shaft, only can move up and down.
Between impeller (14) and the rotating shaft (20) square key (15) is set, impeller is fixed in the rotating shaft.
