Description
Technical field
The utility model relates to a kind of automobile gearbox equipment, is specifically related to the two intermediate shaft structure odd-side spraying lubricating device of heavy goods vehicle.
Background technique
Gearbox is one of component main in car transmissions, can play the effect of slowing down and increasing and turning round and realize forward-reverse.Main tank in current domestic heavy duty automobile gear box and odd-side mainly adopt two intermediate shaft structure.When on the vehicle frame that gearbox is arranged on heavy-duty car, two axles in two intermediate shaft structure odd-side present one high and one low, after adding lubricant oil by oiling standard, Gear Contact on axle is on the lower to lubricant oil, Gear Contact on axle is by the top less than lubrication, in vehicle traveling process, lubricant oil has got rid of and has carried out splash lubrication by pinion rotation on the lower.The defect existed is: when heavy-duty car under static state starts, owing to there being the reason of major-minor case structure, main tank is when car starts rear neutral position, odd-side does not work but substantially remains static, at this moment in odd-side higher position jack shaft on gear and gears meshing on output shaft be in non lubricant oil state, after low-speed heave-load starting, in odd-side higher position jack shaft on gear and gears meshing on output shaft be in dry grinding state, gears meshing surface temperature is sharply raised, easily cause gear failure, reduce the working life of gear, substantially increase the cost of transportation of car load.
Summary of the invention
The purpose of this utility model overcomes above-mentioned defect, there is provided a kind of heavy goods vehicle two intermediate shaft structure odd-side spraying lubricating device, to overcome when heavy-duty car under static state starts starting because the cog dry grinding state that to cog with output shaft of the jack shaft of higher position in low-speed heave-load, odd-side engages and causes Surface of action temperature sharply to raise and damage the defect of gear.
For realizing above object, the two intermediate shaft structure odd-side spraying lubricating device of the utility model heavy goods vehicle comprises dynamo-electric oil pump and the power switch that is brought oil pipe and lower oil pipe, the lower oil pipe being positioned at dynamo-electric oil pump one end is connected to gear box sub-case bottom half, the upper oil pipe of the other end is connected to above gear box sub-case casing, controls dynamo-electric operation of oil pump by power switch.
Above-mentioned pair of intermediate shaft structure odd-side injection system design has following characteristics:
1, increase a dynamo-electric oil pump, make the lubricant oil in gearbox have circulation means.
2, the lower oil pipe of dynamo-electric oil pump one end is connected to bottom half, the upper oil pipe of the other end is connected to above casing, lubricant oil in gearbox is finally got back to casing from bottom half to dynamo-electric oil pump above casing again, define a set of oil circulation system, save lubricant oil, improve economic benefit.
3, dynamo-electric operation of oil pump is controlled by power switch, when making heavy-duty car power supply be in open mode, dynamo-electric oil pump just can work, the gear engagement position be transported to by lower oil pipe by the lubricant oil of bottom half on the gear of the upper jack shaft of higher position in casing and output shaft carries out pressure lubrication, avoid gear because of the damage caused of dry grinding, improve the working life of gear, reduce the maintenance rate of gearbox, substantially increase the transport benefits of car load.
Adopt the two intermediate shaft structure odd-side spraying lubricating device of the heavy goods vehicle of said structure, solve due to when heavy-duty car under static state starts starting because the gear on the jack shaft of higher position in low-speed heave-load, odd-side and the gears meshing on output shaft are in dry grinding state, make gears meshing surface temperature sharply raise the problem causing gear failure, improve the working life of gear, reduce the maintenance rate of gearbox, substantially increase the transport benefits of car load.
Accompanying drawing explanation
Fig. 1 is the two main cross-sectional schematic of intermediate shaft structure odd-side spraying lubricating device structure of the utility model heavy goods vehicle.
Fig. 2 is the two intermediate shaft structure odd-side spraying lubricating device structure schematic side view of the utility model heavy goods vehicle.
Reference character: main shaft assembly 1, main shaft output gear 2, spray bar 3, nut 4, upper oil pipe 5, synchronizer assembly 6, output shaft gear 7, output shaft 8, dynamo-electric oil pump 9, power switch 10, elastic cable paper 11, lower oil pipe 12, lower jack shaft 13, hollow bolt 14, casing 15, upper jack shaft 16.
Embodiment
Below in conjunction with the drawings and specific embodiments, the two intermediate shaft structure odd-side spraying lubricating device of the utility model heavy goods vehicle is described in further detail.
The two intermediate shaft structure odd-side spraying lubricating device of the heavy goods vehicle of the utility model shown in Fig. 1 ~ Fig. 2 comprises dynamo-electric oil pump 9 and the power switch 10 that is brought oil pipe 5 and lower oil pipe 12, the lower oil pipe 12 being positioned at dynamo-electric oil pump 9 one end is connected to bottom gear box sub-case casing 15, the upper oil pipe 5 of the other end is connected to above casing 15, controls dynamo-electric oil pump 9 work by power switch 10.
When concrete installation is implemented, automobile frame installs a dynamo-electric oil pump 9, and drilled through by the screw thread at hollow bolt 14 position bottom casing 15, one end of lower oil pipe 12 is fixed on bottom casing 15 by hollow bolt 14, and the other end is connected with the import of dynamo-electric oil pump 9; Drilled through by the screw thread at spray bar 3 position above casing 15, one end of upper oil pipe 5 is fixed on above casing 15 by spray bar 3 and nut 4, and the other end is connected with the outlet of dynamo-electric oil pump 9, material is thus formed a set of oil circulation system; Control dynamo-electric oil pump 9 by power switch 10 to work.
When heavy-duty car under static state starts, power switch 10 is energized, dynamo-electric oil pump 9 is started working, the lubricant oil in casing 15 is made to be transported to dynamo-electric oil pump 9 by hollow bolt 14, lower oil pipe 12, lubricant oil is transported on spray bar 3 by upper oil pipe 5 again by dynamo-electric oil pump 9, from point hydraulic fluid port ejection spray bar 3, pressure lubrication is carried out to the gear engagement position on the gear of upper jack shaft 16 and output shaft 8; When heavy-duty car advances, huge moment of torsion is delivered on lower jack shaft 13 and upper jack shaft 16 by the main shaft output gear 2 in main shaft assembly 1, under the effect of synchronizer assembly 6, is transferred on output shaft 8 by output shaft gear 7, completes the output of moment of torsion.
Cause has carried out pressure lubrication to the gear engagement position on the gear of upper jack shaft 16 and output shaft 8, make heavy-duty car when starting to walk low-speed heave-load, gear engagement position is lubricated fully, improve the working life of gear, reduce the maintenance rate of gearbox, substantially increase the transport benefits of car load.
