Abstract

The utility model discloses a power output of dumper truck, composed of an air nozzle, a push rod, an output shaft, a compression spring, etc. The output shaft is a quill shaft. The outer end of the output shaft is provided with a spline sleeve. The inner part of the output shaft is not leaded through. The push rod is sealed and arranged in a housing by a bottom end cover. The utility model has the advantages of simple structure, good sealability, oil-tight, being easy to process and install, and being suitable to various automobiles for use.

Description

The dumping truck power takeoff

Technical field

The utility model belongs to a kind of automobile propulsion box, relates to the vehicular spare parts field.

Background technology

At present, existing end face convolution propulsion box has had significant improvement compared with traditional shift fork gear shift clutch structure, the patent No. is that the application of 96245382.x discloses a kind of propulsion box, be that push rod is located in the output shaft, arrangement of clutch adopts the spline claw collar, and passes the long gain of output shaft, be installed on the push rod with push rod pin, it moves with push rod under piston action, by spline fitted, with the output gear outputting power that has the tooth embedding.This propulsion box volume is little, and load-carrying capacity is big, but also has following point: 1) output shaft is a hollow shaft, and sealing is stifled and seal ring sealing by oil, processed complex, excessive fuel consumption easily; 2) be split type between rear side housing and the cylinder cap, be difficult to seal that easily leak, processed complex is difficult to guarantee both concentricitys, after finishing cylinder body processing, need process cylinder barrel in addition, the time-consuming material expense of taking is assembled man-hour; 3) output shaft is crossed and is held logical flange to be connected with the cylinder body split, needs processing at twice, is difficult for the assurance concentricity, and the assembling back easily produces leakage of oil.The application of the patent No. 01229325.3 has solved the problems referred to above, but dynamical axis is split processing, spline fitted, and power output is little; Poor rigidity, processed complex, service life is short.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, thereby provides a kind of outputting power strong, simple and reasonable, and no leak is convenient to process stack-mounted dumping truck power takeoff.

The purpose of this utility model realizes in the following way:

This power takeoff is made up of vapour lock 1, push rod 3, bottom cover 9, output shaft 14, compressing spring 16, output gear 17, input gear 18, input shaft 22 and housing 20, it is characterized in that, output shaft 14 1 end perforates are hollow, the other end is the entity axle, end through hole in the hole has compressing spring 16, one end of compressing spring 16 links to each other with the moving push rod 5 of pair, the surface of output shaft also has spline outside the hole, with spline housing 25 sliding block joints, bottom cover 9 is encapsulated in push rod 3 in the housing 20 by screw 6 and seal ring 10.

The utility model compared with prior art has following advantage:

1) the spline outputting power is strong, and long service life is quick on the draw.Because not conducting in the middle of the output shaft can effectively prevent leakage of oil, and is simple in structure, be convenient to processing.

2) having cancelled the flange of exporting axle head connects.Directly output shaft is loaded in the housing by bearing and seal ring.One axon is convenient to the time processing moulding, and is time saving and energy saving, guaranteed concentricity, simplified mechanism, prevents leakage of oil.

3) bottom cover is connected with housing with seal ring by screw with housing, has omitted the cylinder cap of former mechanism, and better tightness is convenient to guarantee concentricity, has simplified mechanism, has saved raw material and man-hour.

Description of drawings

Below in conjunction with secondary figure the utility model is further described:

Fig. 4 is the spline housing front view.

Fig. 5 is the lateral plan of Fig. 4.

In Fig. 1: 1 vapour lock; 2 seal rings; 3 push rods; 4 steel balls; 5 secondary moving push rods; 6 rivets; 7 screws; 8 spring chairs; 9 bottom covers; 10 seal rings; 11 copper packings; 12 needle rollers; 13 bearings; 14 output shafts; 15 back-up rings; 16 compressing springs; 17 output gears; 18 input gears; 19 gear rings; 20 housings; 21 bearings; 22 input shafts; 23 jackscrews; 24 copper packings.25 spline housings.

The specific embodiment

See Fig. 1: push rod 3 compressing steel balls 4 can promote secondary moving push rod 5, and overcome spring pressure and move to right, and secondary moving push rod 5 links to each other with spline housing 25 with output shaft 14 by rivet 6, and rotates with output shaft.Spline housing 25 moves to right with the moving push rod of pair and drives output gear 17 rotations, drives input gear 18 and input shaft 22 rotations simultaneously, finishes the clutch power taking, and spring 16 is finished in power taking, and the moving push rod 5 of pair is resetted.

The utility model can be used for multiple vehicle, and is simple in structure, be convenient to installation and processing.
