This beach buggy machinery parking device comprises parking brake seat 2, Rocker arm 4, worm screw 8, snail cover 9, snail cover 9 fixes at parking brake seat 2 inner, be provided with in parking brake seat 2 and overlap 9 worm screws cooperatively interacted 8 with snail and parking brake seat 2 is stretched out in above-mentioned worm screw 8 outer end; Rocker arm 4 is connected with worm screw 8 outer end; brake caliper piston 10 push rod 17 stretches out caliper 1 and is resisted against on worm screw 8 interior edge face; when rotating arm 4, worm screw 8 rotates thereupon and pushes ahead.
Parking brake seat 2 cross section, in " convex " font, can be good at the connection coordinating worm screw 8 and snail cover 9, fixed.Parking brake seat 2 is connected with caliper 1 by hexagon socket head cap screw, and structure is simple, fixed, convenient disassembly.
As shown in Figure 3 and Figure 4, snail overlaps 9 profiles in " D " type, is fixed in parking brake seat 2 by interference fit.Such structural design, is not easy wearing and tearing, fixed.It is the square threaded form cooperatively interacted that worm screw 8 exterior edge face and snail overlap 9 interior edge faces, number is 5, lift angle α is 18 °, and large footpath d is of a size of 13mm, and outer diameter D is of a size of Φ 16mm, pitch is 3.5mm, tooth height is 1.3mm, and worm screw 8 often rotates 10 °, worm screw 8 lift 0.6mm, that is when worm screw 8 rotates 10 °, worm screw 8 anterior displacement 0.6mm.
Worm screw 8 outer end is hexagonal column and offers the through hole matched with the outer end of worm screw 8 in hexagonal column in Rocker arm 4 in the heart, Rocker arm 4 offers drag-line hole 15.Such worm screw 8 outer end configuration design, uniform force, can reduce equipment attrition, and Rocker arm 4 drag-line hole 15 is connected with manual drag-line, and during parking, manual steering force pulls Rocker arm 4 to rotate by drag-line, and worm screw 8 rotates thereupon.
Adjustment bolt 5 is provided with in parking brake seat 2, worm screw 8 offers central through bore, adjustment bolt 5 interts adjustment bolt 5 in worm screw 8 and above-mentioned and is threaded with worm screw 8 the inner, the parking gap 16 of 0.5 ~ 1mm is had between adjustment bolt 5 and brake caliper piston 10 push rod 17, the return quantity space of brake caliper piston 10 when removing hydraulic coupling being ensured, preventing product tape from stopping.
Rocker arm 4 outer side surface is provided with self-locking nut 6 and above-mentioned self-locking nut 6 be set in adjustment bolt 5 on and self-locking nut 6 with adjust bolt 5 be threaded, self-locking nut 6 has the advantages that intensity is high, reliability is strong, when self-locking nut 6 is locked, can ensure that adjustment bolt 5 is fixed, prevent people's malfunction from adjusting bolt 5 and affecting parking gap 16, in addition, self-locking nut 6 can play the effect of antivibration.
Rocker arm 4 is provided with when acting on Rocker arm 4 after external force disappears, and brake caliper piston 10 and worm screw 8 can be made to return the resetting-mechanism of initial position.In the present embodiment, resetting-mechanism is return spring 7, and the effect of return spring 7 is that Rocker arm 4 is resetted, and worm screw 8 turns round, and initial value is recovered in parking gap 16, and beach buggy braking system recovers normal work.
Along with the wearing and tearing of braking plate 11, brake caliper piston 10, under the effect of rectangular seal 13, has clearance automatic compensation function, and brake caliper piston 10 is constant with braking plate 11 gap.Parking gap 16 can be increasing, when worm screw 8 lift is not enough to make up parking gap 16, must adjust by the adjusting method in parking gap 16.
The adjusting method in concrete parking gap 16: unclamp self-locking nut 6, turn clockwise adjustment bolt 5, promotes brake caliper piston 10 and move forward, simultaneously swivel wheel, when have band stop phenomenon time, convolution adjustment bolt 5 adjusts 0.5 to 0.9 circle, after adjusting, grabs pressure service braking sytem handle, repeatedly brake several times, prop wheel, rotating-wheel checks whether that band is stopped, and then illustrates that adjustment is correct as stopped without band.
In an initial condition, have the parking gap 16 of 0.5 ~ 1mm between adjustment bolt 5 and brake caliper piston 10 push rod 17, now braking system can normally work this beach buggy machinery parking device.
This beach buggy machinery parking device is when parking braking, and people pulls Rocker arm 4 to rotate for manual control power by drag-line, and worm screw 8 rotates thereupon and pushes ahead; After eliminating parking gap 16, promote brake caliper piston 10 and move forward, and make brake caliper piston 10 extrude braking plate 11, thus make braking plate 11 extrude brake disc 3, produce parking power, realize the object of parking.
This beach buggy machinery parking device is when removing parking, because return spring 7 is in extended state when Rocker arm 4 rotates before, when acting on the external force on Rocker arm 4 and disappearing, return spring 7 bounces back under its own resilient effect, thus drive Rocker arm 4 counterrotating and reset, meanwhile under the effect of Rocker arm 4, worm screw 8 turns round and worm screw 8 and brake caliper piston 10 is resetted, and initial value is recovered in the parking gap 16 between brake caliper piston 10 and adjustment bolt 5, and beach buggy braking system recovers normal work.
