Abstract
The utility model relates to a fork truck brake, in particular to a running and parking integrated fork truck brake which comprises a base plate, a brake drum, brake wheel cylinders and brake shoes. The fork truck brake is mainly and technically characterized in that a sickle-shaped hand brake pull rod is in clearance fit with a brake shoe II through a pin, and the head of the pin is firmly clamped by a clamp spring to limit the vertical clearance between the hand brake pull rod and the brake shoe II; and one end of an arch bridge-shaped hand brake push rod is in clearance fit with a brake shoe I through a pin, and the end surface is padded with a spring shim to eliminate the vertical clearance between the pin-connected hand brake push rod and the brake shoe I. The utility model combines the running and parking functions, simultaneously has the clearance self-regulating function, decreases parking brake assemblies, brake drums and connecting mechanisms, and effectively saves raw materials and the manufacturing cost.
Description
Technical field:
The utility model relates to a kind of fork truck drg, is meant a kind of row fork truck in integral type drg especially.
Background technology:
5-6T level fork truck drg is divided into wheel braking (service brake) and braking (braking during standstill) two mechanisms of central authorities at present, needs two secondary stop mechanisms, manufacturing cost height and complicated operation.
Summary of the invention:
The utility model provides a kind of row fork truck in one drg that reduces raw MAT'L and manufacturing cost.
The utility model is achieved by the following technical solution: a kind of row fork truck in one drg, comprise base plate, brake wheel, brake cylinder, brake shoe brake cheek, its major technique feature is sickleshaped parking brake lever and brake shoe brake cheek II pin free-running fit, the pin head is with jump ring card jail, about restriction parking brake lever and the brake shoe brake cheek II between the gap; Arch-shaped hand braking push rod one end and brake shoe brake cheek I pin free-running fit, end face is encased inside spring shim, connect hand braking push rod and brake shoe brake cheek I above-below direction gap to eliminate pin, selling head then fixes with jump ring, hand braking push rod one end pin and parking brake lever close-fitting, hand braking push rod U type groove inserts the pin free-running fit, is between brake shoe brake cheek II and the parking brake lever; Hand braking cable wire one end is stuck in the parking brake lever afterbody;
The described hand braking cable wire other end connects handle;
Pin is fixed on close-fitting on the base plate; rocker arm pin is fixed on brake shoe brake cheek I and goes up close-fitting; rocking arm and rocker arm pin free-running fit; the rocker arm pin head penetrates spring cotter; guarantee rocking arm and brake shoe brake cheek I gap; top rod one end hook is lived pin; the other end is hung in the rocking arm hole, and spring hanging plate one end is hung in the rocking arm hole, and the other end is hung in the ratchet holes; another pin and brake shoe brake cheek I close-fitting; torsion spring is installed on the pin, and an end is spacing with circular arc in the brake shoe brake cheek I, and ratchet snaps in the cotter way; push down the ratchet pusher dog with the torsion spring other end, and it is close on the adjust the clearance tooth.
The driving of the utility model collection is an one with Parking, and tool is joined the automatic play compensation function simultaneously, has reduced parking brake assembly, brake wheel and bindiny mechanism, has effectively saved raw MAT'L and manufacturing cost.These type drg diameter 317.5 width 100, hand braking push rod, parking brake lever adopt cast steel material, its intensity height.Its deceleration and stopping performance steadily, reliably satisfies the car load demand.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2, Fig. 3 are the local structure scheme drawing of braking during standstill;
Fig. 4 is the automatic play compensation structural representation.
The specific embodiment:
As shown in Figure 1-Figure 3, one's own profession fork truck in one drg comprises base plate 8, brake wheel, brake cylinder 9, brake shoe brake cheek, sickleshaped parking brake lever 10 and brake shoe brake cheek II 7 usefulness pins 3 free-running fits, sell 3 heads with jump ring 11 card jail, restriction parking brake lever and brake shoe brake cheek II about in the of 7 between the gap; Arch-shaped hand braking push rod 12 1 ends and brake shoe brake cheek I 6 usefulness pins 1 free-running fit, end face is encased inside spring shim 13, connect hand braking push rod and brake shoe brake cheek I 6 above-below direction gaps to eliminate pin 1, it is fixing with jump ring 14 to sell 1 head then, hand braking push rod one end pin 2 and parking brake lever close-fitting, hand braking push rod U type groove inserts pin 2 free-running fits, is between brake shoe brake cheek II 7 and the parking brake lever; Hand braking cable wire 15 1 ends are stuck in the parking brake lever afterbody, and the hand braking cable wire other end connects handle 16.
As Fig. 1, shown in Figure 4, pin 5 is fixed on close-fitting on the base plate 8; rocker arm pin 17 is fixed on brake shoe brake cheek I and goes up close-fitting; rocking arm 18 and rocker arm pin free-running fit; the rocker arm pin head penetrates spring cotter 19; guarantee rocking arm and brake shoe brake cheek I gap, top rod 20 1 end hooks firmly sell 5, and the other end is hung in the rocking arm hole; spring hanging plate 21 1 ends are hung in the rocking arm hole; the other end is hung in ratchet 22 holes, pin 4 and brake shoe brake cheek I close-fitting, and torsion spring 23 is installed on the pin 5; end is spacing with circular arc in the brake shoe brake cheek I; ratchet snaps in pin 4 grooves, pushes down the ratchet pusher dog with the torsion spring other end, and it is close on the adjust the clearance tooth 24.Adjust the clearance tooth 24 connects adjust the clearance silk 25, adjust the clearance cover 26.
During service brake, depress the stretcher master cylinder and give the brake cylinder fuel feeding, brake cylinder is pushed brake shoe brake cheek open to two ends, brake shoe brake cheek II is subjected to brake cylinder thrust F, to open direction identical with the brake wheel direction because of brake shoe brake cheek II, produce growth trend and make power, push away the F ' that many bigger to brake shoe brake cheek I, then stressed F of brake shoe brake cheek I and F ' than F by clearance adjuster.Simultaneously, two brake shoe brake cheek also bear positive pressure FN1, FN2 and friction force Ff1, the Ff2 that brake wheel acts on friction lining, reach braking effect.Drg is owing to put on the wheel cylinder, and it is more steadily reliable to have increased its deceleration and stopping performance of the braking arm of force.
During braking during standstill, handle spurs hand braking cable wire head, the hand braking cable wire other end is stuck in the hand lever afterbody, the pulling hand lever is a center of circle left-hand revolution with pin 3, after brake shoe brake cheek II pastes firm brake wheel, the pin 2 that is installed on the hand lever promotes hand braking push rod, and hand braking push rod connecting pin 1 is outwards pushed brake shoe brake cheek I open and pasted firm brake wheel, and brake shoe brake cheek I and brake shoe brake cheek II and brake wheel generation this moment friction force reaches the braking during standstill effect.
The clearance self-regulating principle: when reversing, brake wheel clickwise, brake shoe brake cheek II push up firm base plate position-limited trough, and brake shoe brake cheek I opens; Top rod pulling this moment rocking arm is center of circle left-hand revolution with the rocker arm pin; rocking arm drives the spring hanging plate upward movement; spring hanging plate is held ratchet simultaneously; this moment, ratchet was a center of circle clickwise with pin 4; upwards stir the clearance adjuster gear; to extrapolation adjust the clearance silk, shoes is outwards opened by thrust the rotation of adjust the clearance gear, gap between compensation drg and the brake wheel by connecting thread.Every adjustment one tooth can compensate the 0.04mm gap.
