The dry brake such as caliper disc or drum-type, working life is shorter, changes and safeguards frequent, being not suitable for the working environment of requirement of explosion proof, being thus not suitable for mining pick up Brake for vehicle; And single-acting wet-type hydraulic brake, being only simple hydraulic driving service brake, in order to realize parking braking and the emergency braking of picking-up vehicle, often needing to configure multiple break on same chassis, take installing space, increase user cost.
Summary of the invention
The utility model provides a kind of picking-up vehicle double-action wet-type hydraulic brake, is intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the brake casing be connected with picking-up vehicle axle housing; Described brake casing comprises: the first seal ring and the second seal ring; The first described seal ring and the second seal ring are arranged in the groove of brake casing; Also comprise: brake seat; Described brake seat comprises: friction plate, for sealing the first oil sealing and first screw of break oil pocket inner fluid; Described friction plate to be connected with brake seat by spline and can to move to axial; Described brake seat is connected by the first screw with pick up semiaxis; Also comprise: ring gear; Described ring gear comprises: antithesis sheet; Described ring gear is connected with brake casing by the second screw; Described antithesis sheet is connected by spline ring gear and can move to axial; Also comprise: blind flange; Described blind flange comprises: the second oil sealing; Described blind flange is connected with ring gear by the 3rd screw; The second described oil sealing is for sealing break oil pocket inner fluid; Also comprise: parking piston; Described parking piston comprises: the 3rd seal ring, the 4th seal ring and brake spring; The 3rd described seal ring and the 4th seal ring are arranged in the groove of parking piston; Described parking piston to be arranged in ring gear and to form the first oil cylinder with the 3rd seal ring, the 4th seal ring; Also comprise: driving piston; Described driving piston comprises: caging bolt, Returnning spring and guider screw; Described caging bolt for compression reseting spring and be arranged on driving piston; Described guider screw leads for brake spring and is arranged on driving piston; Described driving piston to be arranged in brake casing and to form the second oil cylinder with the first seal ring, the second seal ring.
Compared with prior art, the beneficial effects of the utility model are: by having service brake, the wet-type hydraulic brake of parking braking and emergency braking is applied on picking-up vehicle, and picking-up vehicle break has explosion-proof performance, can be applicable to mining transportation operation; Service brake, parking braking and emergency braking three kinds of function i ntegration, in a break, make brake structural compacter, decrease the installing space of break.Wet brake friction plate works in fluid, and friction plate does not wear and tear, and therefore break has the long lifetime and reduces the maintenance cost of pick up break.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As seen from Figure 1, the utility model comprises: the brake casing 1 be connected with picking-up vehicle axle housing; Described brake casing 1 comprises: the first seal ring 15 and the second seal ring 16; The first described seal ring 15 and the second seal ring 16 are arranged in the groove of brake casing 1; Also comprise: brake seat 13; Described brake seat 13 comprises: friction plate 8, for sealing the first oil sealing 12 and the first screw 14 of break oil pocket inner fluid; Described friction plate 8 to be connected with brake seat 13 by spline and can to move to axial; Described brake seat 13 is connected by the first screw 14 with pick up semiaxis; Also comprise: ring gear 7; Described ring gear 7 comprises: antithesis sheet 9; Described ring gear 7 is connected with brake casing 1 by the second screw 20; Described antithesis sheet 9 is connected by spline ring gear 7 and can move to axial; Also comprise: blind flange 10; Described blind flange 10 comprises: the second oil sealing 11; Described blind flange 10 is connected with ring gear 7 by the 3rd screw 21; The second described oil sealing 11 is for sealing break oil pocket inner fluid; Also comprise: parking piston 3; Described parking piston 3 comprises: the 3rd seal ring 4, the 4th seal ring 5 and brake spring 2; The 3rd described seal ring 4 and the 4th seal ring 5 are arranged in the groove of parking piston 3; Described parking piston 3 to be arranged in ring gear 7 and to form the first oil cylinder C with the 3rd seal ring 4, the 4th seal ring 5; Also comprise: driving piston 17; Described driving piston 17 comprises: caging bolt 18, Returnning spring 19 and guider screw 6; Described caging bolt 18 for compression reseting spring 19 and be arranged on driving piston 17; Described guider screw 6 leads for brake spring 2 and is arranged on driving piston 17; Described driving piston 17 to be arranged in brake casing 1 and to form the second oil cylinder D with the first seal ring 15, second seal ring 16.
Working principle of the present utility model is: service brake is discharged by hydraulic braking spring, and parking braking and emergency braking are discharged by spring braking hydraulic pressure.Under original state, under namely picking-up vehicle is in halted state, break is in parking braking state, due to the effect of brake spring 2 by parking piston 3 and driving piston 17 pressing friction sheet 8, antithesis sheet 9 on blind flange 10, friction plate group produces friction torque under pressure and realizes parking braking.When the pneumatic operation of pick up, hydraulic oil enters oil cylinder C by A mouth, under oil pressure effect, promote the power that parking piston 3 overcomes brake spring 2 move right, promote driving piston 17 by Returnning spring 19 and caging bolt 18 to move right simultaneously, the earth pressure release of friction plate group, friction plate 8 and antithesis sheet 9 recover gap, and parking braking discharges, and brake seat 13 and brake casing 1 can relatively rotate.When picking-up vehicle needs braking under steam, hydraulic oil enters oil cylinder D from B mouth, the power that promotion driving piston 17 overcomes Returnning spring 19 by caging bolt 18 is moved to the left, and pressing friction sheet 8, antithesis sheet 9, on blind flange 10, produce friction torque and realize service brake; When hydraulic oil is discharged from oil cylinder D by B mouth, driving piston 17 is moved right by caging bolt 18 under Returnning spring 19 acts on, and service brake discharges.When an emergency happens, fluid is discharged from oil cylinder C and oil cylinder D simultaneously, and parking piston 3 and driving piston 17 pressing friction sheet group under the effect of brake spring 2, realize the emergent stopping of picking-up vehicle.
