Abstract
The utility model discloses a kind of loaded vehicle main reducer of middle axle gear forced lubrication device, it comprises gear hub, master subtracts dynamo-electric oil pump and automobile power source; Be provided with oil-sucking hole bottom described gear hub, gear hub is also provided with prefabricated oil inlet hole, oil groove and nozzle opening, by the oil circuit UNICOM in gear hub between oil-sucking hole and oil inlet hole, this nozzle opening is positioned at above driving gear and idle pulley engaging position; Described master is subtracted dynamo-electric oil pump and to be arranged on bottom gear hub by bolt and to be communicated with oil-sucking hole, is connected by electrical wiring on automobile power source.Adopt this structure loaded vehicle main reducer of middle axle gear forced lubrication device, the driving gear that can realize being in starting dry grinding state in heavy main reducer of middle axle of automobile assembly carries out pressure oil jet lubrication, thus solve due to when automobile is started to walk when low-speed heave-load because driving gear can not get feed lubrication in the very first time, cause gear to dry grind the problem heating up and damage.
Description
Technical field
The utility model relates to middle bridge of heavy duty automobile main gearbox assembly, particularly loaded vehicle main reducer of middle axle gear lubrication device.
Background technique
Loaded vehicle main reducer of middle axle assembly is one of main component in Heavy Truck Driveline system, can play the effect of slowing down and increasing and turning round.After current domestic middle bridge of heavy duty automobile main gearbox assembly is installed to jackshaft, driving gear and idle pulley engaging position are far above Lubricating Oil liquid level, original lubricating structure just need can carry out fuel feeding under the drive of main gearbox assembly middle gear, Problems existing is: when automobile starts in the situation of low-speed heave-load, because vehicle does not have fast running, lubricating structure cannot carry out fuel feeding, when making vehicle starting, driving gear does not obtain sufficient lubrication and the cooling of lubricant oil, gear is caused to be dry grinded and flank of tooth high temperature, cause gear failure, greatly reduce the maintenance operation cost of vehicle.
Summary of the invention
The purpose of this utility model overcomes above-mentioned defect, a kind of loaded vehicle main reducer of middle axle gear forced lubrication device is provided, the driving gear realized being in starting dry grinding state in heavy main reducer of middle axle of automobile assembly carries out pressure oil jet lubrication, thus solve due to automobile when low-speed heave-load because lubricating structure cannot carry out fuel feeding the very first time, when making vehicle starting, driving gear can not obtain sufficient lubrication and the cooling of lubricant oil, cause gear to be dry grinded and flank of tooth high temperature, cause the problem of gear failure.
For realizing above object, the utility model loaded vehicle main reducer of middle axle gear forced lubrication device comprises gear hub, master subtracts dynamo-electric oil pump and automobile power source; Be provided with oil-sucking hole bottom described gear hub, gear hub is also provided with prefabricated oil inlet hole, oil groove and nozzle opening, by the oil circuit UNICOM in gear hub between oil-sucking hole and oil inlet hole, this nozzle opening is positioned at above driving gear and idle pulley engaging position; Described master is subtracted dynamo-electric oil pump and to be arranged on bottom gear hub by bolt and to be communicated with oil-sucking hole, is connected by electrical wiring on automobile power source.
Above-mentioned loaded vehicle main reducer of middle axle gear forced lubrication device design has following characteristics:
1, existincrease oil-sucking hole bottom gear hub, enable the fluid of middle pars basilaris pontis be subtracted dynamo-electric oil pump by master and suck, for driving gear provides source of lubricating.
2, mainly subtract dynamo-electric oil pump and to be arranged on bottom gear hub and with being wired on automobile power source, when automobile power source one is connected, mainly subtract dynamo-electric oil pump and start working, ensure that the promptness that driving gear lubricates well.
3, on gear hub, prefabricated oil inlet hole, oil groove and nozzle opening is provided with, nozzle opening is positioned at above driving gear and idle pulley engaging position, subtract above idle pulley engaging position that lubricant oil that dynamo-electric oil pump drinks up to be transported to by oil inlet hole and oil groove in driving tooth and idle pulley assembly when main, sprayed by nozzle opening, the engaging position of driving gear and idle pulley is lubricated, ensure that gears meshing quality well, greatly reduce vehicle maintenance and operation cost.
Said structure loaded vehicle main reducer of middle axle gear forced lubrication device is adopted to solve because automobile is when low-speed heave-load, sufficient lubrication and the cooling of lubricant oil can not be obtained because lubricating structure cannot carry out driving gear when fuel feeding makes vehicle starting the very first time, cause gear dry grinding and flank of tooth high temperature to cause the problem of gear failure, substantially increase the transport benefits of vehicle.
