Abstract

The utility model discloses a clutch pneumatic force picker having cantilever coaxial tooth inserted end, relating to an accessory for a dump truck. The utility model refers to simple structure relating to a clutch pneumatic force picker, in which an input shaft is used to drive an input cross bridge gear and the tooth inserted of the input gear, aiming at the insufficiency that the prior art that a push rod is used to drive an auxiliary movable push rod provided with an iron ball and then a compression spring is used to drive an output shaft has complicating structure and needs a plurality of parts. The utility model has the technique proposal that the centre section of the input shaft 6 which is arranged on a housing 1 is provided with an input cross bridge gear 2 which is provided with a shaft bearing 5; the input cross bridge gear 2 forms a spline tooth inserted shape; the middle part has a long waist-hole. A pin 7 is assembled in the pin hole of the input cross bridge gear 2 and the long waist-hole of the input shaft 6. One end of the input shaft 6 is provided with an air chamber 4, the other end of the input shaft 6 is inserted in a cantilever sleeve 8 which is arranged in the housing 1 and is contiguous with one end of a return spring 12. The cantilever sleeve 8 is assembled externally with the input gear 3 which is provided with the shaft bearing 5 and forms the spline tooth inserted shape. The input cross bridge gear 2 is meshed with the output gear 11 which is arranged on the output shaft 10 of the housing 1. The external end cover of the air chamber 4 is provided with an air nozzle 9.

Description

The pneumatic power takeoff of the coaxial tooth embedding of cantilever end face clutch

One, technical field

The utility model relates to the accessory that dumping truck is used, the pneumatic power takeoff of the coaxial tooth embedding of especially a kind of cantilever end face clutch.

Two, background technology

At present, existing end face convolution power takeoff has had significant improvement compared with traditional shift fork gear shift clutch structure.At number of patent application is 01229325.3, discloses " a kind of dumping truck power takeoff ", adopts push rod to promote the moving push rod of pair of band steel ball, and then by compressing spring promotion output shaft mechanical clutch structure, exist complex structure, part is many, weak points such as cost height.

Three, summary of the invention

The purpose of this utility model provides a kind of simple in structure, is directly promoted the pneumatic power takeoff of the tooth embedding clutch of input gap bridge tooth and input tooth by input shaft.

Technical scheme that the purpose of this utility model adopts is, include housing, input gap bridge tooth, the input tooth, input shaft, output shaft, output gear, pull back spring is formed, the input shaft of assembling middle part is equipped with tape spool and is held 5 the input gap bridge tooth that is the spline claw collar in its housing, there is long lumbar hole at the middle part, pin is assemblied in the long lumbar hole of the pin-and-hole of input gap bridge tooth and input shaft, input shaft one end has air chamber, the other end inserts in the cantilever cover that is contained in the housing adjacent with pull back spring one end, be equipped with the input tooth that is the spline claw collar that tape spool holds outside the cantilever cover, import output gear engagement on the gap bridge tooth output shaft interior, on the outer end cap of air chamber valve is housed with being contained in housing.

The utility model, the male splines of input gap bridge tooth cooperates with the female splines of input tooth.

Its working process of the utility model, when being arranged, gas enters air chamber by valve, it is parallel mobile to promote input shaft, the male splines of input gap bridge tooth is combined with the female splines of input tooth, and compression retracteding position spring makes the input tooth rotate and drives and import the gap bridge tooth and also rotate, and pin has been fixed input gap bridge tooth and input shaft, also force the input shaft rotation, input gap bridge tooth and output gear engaging structure also make output gear rotate, and output shaft is rotated; During gas, the pull back spring bounce-back does not make the input shaft return, and the corresponding male splines that makes input gap bridge tooth leaves with the female splines of input tooth, and input gap bridge tooth is not rotated, and causes output gear and output shaft all not to rotate.

The utility model is simple and compact for structure, and it is easy to make assembling, and part is little, and volume is little, and load-carrying capacity is big, work flexibility and reliability, noiselessness, characteristics such as cost is low.Can extensively know the engineering truck and other special vehicle that are used for dumping car, repacking.

Four, description of drawings

Further specify the utility model below in conjunction with accompanying drawing.

Accompanying drawing is the three-dimensional sectional structure scheme drawing of the utility model.

Among the figure: 1-housing 2-input gap bridge tooth 3-input tooth 4-air chamber 5-bearing 6-input shaft 7-pin 8-cantilever cover 9-valve 10-output shaft 11-output gear 12-pull back spring

Five, the specific embodiment

As shown in drawings, input shaft 6 middle parts of assembling are equipped with tape spool and are held 5 the input gap bridge tooth 2, the middle part that are the spline claw collar long lumbar hole is arranged in the housing 1, pin 7 is assemblied in the long lumbar hole of the pin-and-hole of input gap bridge tooth 2 and input shaft 6, the cantilever cover 8 that input shaft 6 one ends have air chamber 4, the other end to insert and are contained in the housing 1 is interior adjacent with pull back spring 12 1 ends, be equipped with tape spool outside the cantilever cover 8 and hold 5 the input tooth 3 that is the spline claw collar, valve 9 is equipped with in output gear 11 engagements on input gap bridge tooth 2 and the output shaft 10 that is contained in the housing 1 on the outer end cap of air chamber.
