Abstract
The invention discloses a forklift brake with integral travelling and parking, relating to a forklift brake, in particular to a forklift brake with integral travelling and parking. The forklift brake comprises a baseboard, a drum brake, a brake cylinder and a brake shoe and has the technical characteristics that a falciform hand braking draw bar is in clearance fit with the brake shoe II by pins; pin heads are tightly clamped by a jump ring; a gap between the hand brake lever and the brake shoe II is restricted; one end of an arch bridge hand braking push bar is in clearance fit with a brake shoe I by pins; and a spring spacer is padded into the end surface so as to eliminate the gap between the upper direction and the lower direction of the hand braking push bar and the brake shoe I connected by pins. The invention integrates travelling and parking into a whole, simultaneously has the automatic adjusting function of gaps, reduces the parking brake assembly, the drum brake and the connection mechanism and effectively saves raw materials and manufacturing cost.
Description
Technical field:
The present invention relates to a kind of fork truck break, be meant a kind of row fork truck break especially in the integral type.
Background technique:
5-6T level fork truck break is divided into wheel braking (service brake) and braking (parking braking) two mechanisms of central authorities at present, needs two secondary arrestment mechanisms, manufacture cost height and complicated operation.
Summary of the invention:
The present invention provides a kind of row fork truck in one break that reduces raw material and manufacture cost.
The present invention realizes through following technological scheme: a kind of row fork truck in one break; Comprise base plate, brake drum, brake cylinder, brake shoe; Its major technique characteristic is that sickleshaped hand brake lever and brake shoe II use the pin Spielpassung; The pin head is with jump ring card jail, about restriction hand brake lever and the brake shoe II between the gap; Arch-shaped hand braking push rod one end and brake shoe I use the pin Spielpassung; End face is encased inside compression spring; To eliminate pin connection hand brake pushrod and brake shoe I above-below direction gap, to sell head then and fix with jump ring, hand braking push rod one end is with pin and hand brake lever close-fitting; Hand braking push rod U type groove inserts the pin Spielpassung, is between brake shoe II and the hand brake lever; Hand braking cable wire one end is stuck in the hand brake lever afterbody;
The described hand braking cable wire the other end connects handle;
Pin is fixed on close-fitting on the base plate, and rocker-arm roller pin is fixed on brake shoe I and goes up close-fitting, and rocking arm and rocker-arm roller pin Spielpassung; the rocker-arm roller pin head penetrates cotter pin guarantee rocking arm and brake shoe I gap, and upper connecting 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 detent holes; another pin and brake shoe I close-fitting, and torsion spring is installed on the pin, and an end is spacing with circular arc in the brake shoe I; ratchet snaps in the cotter way, pushes down the ratchet pusher dog with the torsion spring the other end, and it is close on the gap adjustment tooth.
It is one with Parking that the present invention collects driving, and the while tool is joined the gap and adjusted function automatically, has reduced parking brake assembly, brake drum and bindiny mechanism, has effectively practiced thrift raw material and manufacture cost.These type break diameter 317.5 width 100, hand braking push rod, hand brake lever adopt cast steel material, and its intensity is high.Its braking ability steadily, reliably satisfies the car load demand.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2, Fig. 3 are the partial structurtes schematic representation of parking braking;
Fig. 4 is a gap automatic adjusting structure schematic representation.
Embodiment:
Like Fig. 1-shown in Figure 3; One's own profession fork truck in one break comprises base plate 8, brake drum, brake cylinder 9, brake shoe, sickleshaped hand brake lever 10 and brake shoe II 7 usefulness pins 3 Spielpassung; Sell 3 heads with jump ring 11 card jail, restriction hand brake lever and brake shoe II about in the of 7 between the gap; Arch-shaped hand braking push rod 12 1 ends and brake shoe I 6 usefulness pins 1 Spielpassung; End face is encased inside compression spring 13; To eliminate pin 1 connection hand brake pushrod and brake shoe I 6 above-below direction gaps, it is fixing with jump ring 14 to sell 1 head then, and hand braking push rod one end is with pin 2 and hand brake lever close-fitting; Hand braking push rod U type groove inserts pin 2 Spielpassung, is between brake shoe II 7 and the hand brake lever; Hand braking cable wire 15 1 ends are stuck in the hand brake lever afterbody, and the hand braking cable wire the other end connects handle 16.
Like Fig. 1, shown in Figure 4, pin 5 is fixed on close-fitting on the base plate 8, and rocker-arm roller pin 17 is fixed on brake shoe I and goes up close-fitting, and rocking arm 18 and rocker-arm roller pin Spielpassung; the rocker-arm roller pin head penetrates cotter pin 19 guarantee rocking arm and brake shoe I gap, and upper connecting rod 20 1 end hooks firmly sell 5; the other end is hung in the rocking arm hole, and spring hanging plate 21 1 ends are hung in the rocking arm hole, and the other end is hung in ratchet 22 holes; pin 4 and brake shoe I close-fitting, and torsion spring 23 is installed on the pin 5, and an end is spacing with circular arc in the brake shoe I; ratchet snaps in pin 4 grooves, pushes down the ratchet pusher dog with the torsion spring the other end, and it is close on the gap adjustment tooth 24.Gap adjustment tooth 24 connects gap adjustment silk 25, gap adjustment cover 26.
During service brake; Step on the leftover bits and pieces pedal master cylinder and give the brake cylinder fuel feeding, brake cylinder is pushed brake shoe open to two ends, and brake shoe II receives brake cylinder thrust F; To open direction identical with the brake drum direction because of brake shoe II; Produce growth trend and make power, push away the F ' that many bigger to brake shoe I, then stressed F of brake shoe I and F ' than F through slack adjuster.Simultaneously, two brake shoes also bear positive pressure FN1, FN2 and frictional force Ff1, the Ff2 that brake drum acts on friction plate, reach braking effect.Break is owing to put on the wheel cylinder, and it is more steadily reliable to have increased its braking ability of the braking arm of force.
During parking braking; Handle spurs hand braking cable wire head, and the hand braking cable wire the other end is stuck in the hand lever afterbody, and the pulling hand lever is that the center of circle is rotated counterclockwise with pin 3; After brake shoe II pastes firm brake drum; 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 I open and pasted firm brake drum, and brake shoe I and brake shoe II and brake drum generation this moment frictional force reaches the parking braking effect.
The clearance self-regulating principle: when reversing, brake drum turns clockwise, and brake shoe II pushes up firm base plate restraining groove, and brake shoe I opens; Upper connecting rod pulling this moment rocking arm is that the center of circle is rotated counterclockwise with the rocker-arm roller pin; rocking arm drives spring hanging plate and moves upward, and spring hanging plate is held ratchet simultaneously, and this moment, ratchet was that the center of circle turns clockwise with pin 4; upwards stir the slack adjuster gear; gap adjustment gear rotating tee is crossed connecting thread to extrapolation gap adjustment silk, and shoes is outwards opened by thrust, gap between compensation break and the brake drum.Every adjustment one tooth can compensate the 0.04mm gap.
