Abstract
The utility model provides an all-hydraulic gear shift housing for a heavy-duty lorry used in mine and on highway, which belongs to the field of the hydraulic driving for lorries. The utility model is characterized in that the cylinder body type structure with vertical flask joint is adopted; a low-gear distance changing device, an intermediate-gear distance changing device, a high-gear coupling device, and a reverse-gear distance changing device which are hydraulic units are arranged between an input shaft and an output shaft. When the utility model runs in one speed threshold, only the hydraulic unit in the speed threshold runs for charging oil, and other hydraulic units in other speed thresholds blowing in idle running. The hydraulic gear shifting, the hydraulic direction changing, and the hydraulic brake are realized by the oil charging and discharging among the hydraulic units. The utility model has the advantages of no mechanical shock or abrasion in the whole working provess, convenient operation, reliable work, and little need for maintenance.
Description
The utility model belongs to heavy motor vehicle hydraulic transmission field.
Load carrying ability needs more than 360PS (average 12PS per ton) at the diesel motor power of the mining and highway more than the 30t with heavy motor vehicle institute adapted.General mechanical gear box reliable operation normally just more than 300PS, the native land above mining and highway of inside and outside 30t all need adopt hydraulic transmission box with heavy motor vehicle.
At present, worldwide, be applicable to mining and the highway heavy motor vehicle, the multiple functional hydraulic transmission box of function admirable has: the U.S. GM company Allison of Detroit branch hydraulic transmission box and German ZF hydraulic transmission box.These two kinds of serial hydraulic transmission boxes all belong to single tor-con hydraulic transmission system that single centripetal turbine turbine transformer and many gears mechanical gear box combine.Its tor-con is a combined type band coupling operating mode, and can realize coupler lock; Mechanical gear box is realized power shfit and the commutation of stopping by many gears plate clutch; Realize descending and brake snub by the hydraulic brake of special setting and the friction clutch of different gears.The whole transmission device complex structure, manufacture difficulty is big; Particularly the control system link is various, the program complexity, and operation precision requires high; In addition, multi-plate friction clutch exists impact and wearing and tearing in cohesive process, influence service life and functional reliability, and the current maintenance amount is bigger.
The purpose of this utility model is the full hydraulic transmission box that a kind of fluid power gear shift, hydraulic changeover and hydraulic brake easy and simple to handle is provided with heavy motor vehicle for mining and highway, fundamentally eliminate physical shock and wearing and tearing in gear shift, commutation and the braking procedure, improve service life and functional reliability, reduce maintenance capacity.
The purpose of this utility model is achieved in that the input shaft (1) of change speed gear box connects the pump impeller of hydrodynamic unit (3), (4), (5) and (6) simultaneously, be low gear tor-con, mid ranger tor-con, high speed gear impeller disk and reverse gear torque converter pump, hydrodynamic unit (3), (4), the turbine of (5) and (6) then is connected with the output shaft (2) of change speed gear box simultaneously.The input end of change speed gear box has a multiplying wheel right, and mouth has a reducing gear right, and the multiplying wheel of input end is to engagement and two kinds of external toothings in having with the right engagement system of the reducing gear of mouth.When change speed gear box during, has only the oil-filled work of hydrodynamic unit (tor-con or impeller disk) of this grade, the equal air blast idle running of the hydrodynamic unit of other gear in a certain gear engaged.Oil-filled and the oil extraction (oil-filled another oil extraction) by time between adjacent speed threshold hydrodynamic unit realizes the fluid power conversion of speed stage; Fill oil extraction by time between low gear tor-con and reverse gear tor-con, realize the fluid power conversion of service direction; Engine idling operation, oil-filled to low gear or mid ranger tor-con, can realize descending and deceleration hydraulic brake slowly; Regulate engine speed, oil-filled to the reverse gear tor-con, can realize descending and deceleration hydraulic brake rapidly, until being stopped fully, automobile stops.
The utility model is because the oil extraction process is filled in fluid power gear shift, hydraulic changeover and hydraulic brake when being a kind of steadily soft, no any mechanical friction, so whole process does not exist physical shock and wearing and tearing, and tractive force can not interrupt in the gearshift procedure, and the commutation action can not carried out under the dead ship condition.Easy and simple to handle, reliable operation, maintenance capacity is few.
Shown in Figure 1 is at a high speed, highway is with the full hydraulic transmission box constructional drawing of heavy motor vehicle.Shown in Figure 2 then is the full hydraulic transmission box constructional drawing of low speed, mining heavy motor vehicle, compared to Figure 1, has just lacked a high speed gear hydraulic coupler, is applicable to the mining heavy motor vehicle of low speed.
Narrate embodiment of the present utility model below in conjunction with accompanying drawing 1.
Input shaft (1) is right by multiplying wheel, drives three pump impellers of low speed tor-con (3), middling speed tor-con (4) and reverse gear tor-con (5) simultaneously, turns to opposite with input shaft.Two turbines of tor-con (3) and (4) are attached on the same axle, pair are connected with the output shaft (2) of change speed gear box by reducing gear.The turbine of reverse gear tor-con (5) links to each other with output shaft (2) with an idler shaft by three gears.Input shaft (1) is right by interior engagement multiplying wheel, drives the pump impeller of high speed impeller disk (6), turns to identical with input shaft.The turbine of impeller disk (6) directly links to each other with output shaft (2).Input shaft (1) is by two pairs of gear drive oil feed pumps (7).
During automotive operation, in hydrodynamic unit (3), (4), (5) and (6), has only the oil-filled work of element, the then air blast idle running of other element.When automobile moves at low speed segment, the oil-filled work of low speed tor-con (3); When the middling speed section is moved, the oil-filled work of middling speed tor-con; When high regime is moved, the oil-filled work of high speed impeller disk; When reversing, the oil-filled work of reverse gear tor-con.The turbine of hydrodynamic unit (3), (4) and (6) is rotated in the forward output (2), and the turbine of reverse gear tor-con then makes output shaft (2) contrarotation.
Fill oil extraction simultaneously by hydrodynamic unit (3), (4) and (6) two adjacent speed thresholds are interelement, realize the conversion of speed stage, tractive force can not interrupt in the switching process.Fill oil extraction by time between low gear tor-con (3) and reverse gear tor-con (5), realize the conversion of service direction, switching motion can not carry out under the dead ship condition.When automobile at down ramp or when running at high speed, as driving engine is placed idle position, simultaneously oil-filled to low speed or middling speed tor-con, then tor-con enters and surmounts damped condition, makes output shaft (2) braking, can realize descending or brake snub slowly; As oil-filled to the reverse gear tor-con, regulate engine speed simultaneously, then tor-con enters the counter-rotating damped condition, produces huge braking force on output shaft, can realize descending or brake snub rapidly, stops until automobile is stopped fully.
