Abstract
The utility model belongs to a transitional component used for converting automotive force into hydraulic force for hydraulic self-discharging automobiles. The utility model is characterized in that the end surface of a connecting flange is vertical to the plane of a base; a driving wheel is in a double-teeth structure which can be directly engaged with a shifting gear; the tooth number of the gear is adjusted, and the shift is directly carried out on a spline shaft; an operating device connected with a shifting shaft is arranged at the outer end of a casing. The utility model realizes generalization of the casing for serial products with different models, and solves the defects of large volume, complicated structure, heavy weight, inconvenient installation and maintenance, etc. existing in the prior art. The utility model has the advantages of simple structure, high durability, high speed ratio, light weight, convenient installation and maintenance, etc., and realizes pneumatic and hand-operated compatibility.
Description
The utility model belongs to the transitional parts that mechanomotive force is changed to hydraulic coupling on the hydraulic dump hoist, and its effect is to give gear type pump to produce hydraulic coupling the transmission of power of driving engine.
Existing propulsion box driving wheel is an individual gears, and structure is unreasonable; Profile is multifarious, is unfavorable for installation, maintenance, and volume is big, and heavy, the base portion of manual, pneumatic two kinds of products has nothing in common with each other, and does not have a commonality.Chinese patent 21678845 discloses the automobile-used propulsion box of a kind of no shift fork end face disengaging type, and its driving wheel still is the individual gears structure.
The purpose of this utility model is: overcomes the deficiencies in the prior art and a kind of designs simplification, attractive and durable is provided, and the speed ratio height, in light weight, easy to installation and maintenance, and can realize pneumatic and manual compatible duplex tooth propulsion box.
The purpose of this utility model is achieved in that its housing adopts the binding end face of flange general housing vertical with base plane, to be suitable for the needs of different model, series, is more convenient for installing.Enclosure interior, driving wheel are can be directly and power shift gear ingear duplex toothing, have cut carrier gear (and axle, bearing etc.), directly shift gears on castellated shaft, and having solved shifts gears with little in the past causes the problem of parts rapid wear, has simplified inner structure.
Feature of the present utility model also is: housing top respectively has one to can be used for adorning air chamber or bar handle and two stifled holes of oil with gearshift axle opposite end, to realize the two-way general of manual type and pneumatic type.
Feature of the present utility model also is: increase the driving gear external diameter and the number of teeth, make speed ratio bring up to 1: 1.673 from 1: 1.026.
Feature of the present utility model also is: operating control links to each other with the gearshift axle, and places the housing outer end.On unified agent structure, its operating control is for manual, the Pneumatic shift device of difference adapted, to form the product line of two kinds of different maneuverability patterns; In pneumatic series of products, adopt external air chamber, be easy for installation and maintenance, solved the problem that built-in air chamber is easy to ponding, improved the gearshift reliability.
The utility model compared with prior art owing to adopted the duplex toothing, has cut carrier gear in design, reduced the part number, increases the consumable accessory size, has improved properties of product, makes structure more reasonable; Owing to improved speed ratio, satisfied the needs of hydraulic dump hoist oil pump speed-raising, improved the lifting force and the rising or falling speed of oil cylinder; Adopt the general-duty housing and simplify inner structure, reduced the weight (product of the same type reduces to 13.5kg by original 28kg) of product and saved raw MAT'L, reduced cost of product.
Fig. 1 is the structural representation of the utility model pneumatic type duplex tooth propulsion box;
Fig. 2 is the structural representation of the utility model manual type duplex tooth propulsion box.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Among Fig. 1, perpendicular with base 3 planes that housing 1 is as a whole with the end face that links flange 2, driving wheel 4 is the duplex tooth, be integral structure, form that power shift gear 8 is contained on the castellated shaft 7 and can slides by a spur gear 5 and a helical wheel 6, shift fork 10 is fixed in gearshift axle 9, under be stuck in power shift gear 8, air chamber 11 is placed on housing, links to each other with source of the gas by valve.Housing top is equipped with oil with gearshift axle 14 places, 9 corresponding holes and is blocked up to realize sealing.When power takeoff is worked, valve open, pressurized air enters air chamber, it is parallel mobile to promote the gearshift axle, make power shift gear 8 and spur gear 5 engagements through shift fork, always the helical wheel 6 that is meshed with dumping car engine mission gear just the torque of driving engine by 1: 1.673 speed ratio through spur gear 5 → gearshift tooth 8 → castellated shaft 7 to the gear type pump transmission, finish the power taking function.
Among Fig. 2,1 is housing, and 2 is butt flange, and 3 is base, 4 is duplex tooth driving wheel, and 8 is power shift gear, and 7 is castellated shaft, and shift fork 10 is fixed on the gearshift axle 9, bar handle 12 links with gearshift axle 9, and 13 is that oil is stifled, can realize gearshift by parallel mobile gearshift axle by drawing handle 12.
