Description
Technical field:
The utility model relates to a kind of and the matching used transfer case of torque converter.
Background technique:
At present, top, market torque converter has used the transfer case that falls apart from output.Common a kind of falling apart from the transfer case as 470mm of using directly is assemblied in the torque converter output terminal, and internal bearings, gear all adopt splash lubrication.To some oil field equipment, this falls apart from less than normal, and the transmission shaft inclination angle that connects workpiece is big, during torque converter low-grade location low cruise, and the bearing lubrication weak effect, easy burn-out, complete machine is short service time, the normal usage requirement that does not reach these equipment.
The model utility content:
The technical problems to be solved in the utility model is: a kind of large distance drop transfer case is provided, falls distance and lubricated deficiency to overcome former fluid power speed changer large distance drop transfer case.
The utility model is to constitute like this: it comprises transfer case housing (1), transfer-case cover (7), in the bottom of transfer case housing (1) transfer case fuel tank (15) is arranged, input shaft (5), jack shaft (2) and following output shaft (13) are arranged in transfer case housing (1), bearing (8) and gear (4) are all arranged on input shaft (5), jack shaft (2) and following output shaft (13), output terminal head at each has needle bearing (10), at each output terminal coupling (9), tooth clutch assembly (11), bearing (12) is arranged.
Liner (6) is arranged between transfer case housing (1) and torque converter, solve the sealing problem that transfer case housing (1) is connected with torque converter.
At input shaft (5), jack shaft (2), following output shaft (14) two ends location collar (3) closed coupling (9) is arranged.
Centre distance between input shaft (5) and the following output shaft (14) is 673mm, is called traditionally and falls distance.Fall apart from comparing with the 470mm of normal use in the market, be referred to as to fall greatly distance.
Oilhole (17) is arranged on input shaft (5), and its throttle orifice diameter is φ 1.5mm.Oilhole (17) docks with the torque converter relevant position, solves to be installed in the lubricated of the middle needle bearing (10) of input shaft (5).Torque converter flows back to the lubricant oil of fuel tank (15), by hole (18), through the lubricated needle bearing (10) that is installed in its rear end of the inner oilhole of jack shaft (2), the needle bearing (10) that is installed in down the interior two ends of output shaft (14) leans on the hole (16) in transfer case housing (1), the transfer-case cover (7) and splashes lubricant oil is provided jointly, the inner oil duct of following output shaft (14) is communicated with the two ends needle bearing, strengthens lubricant oil and flows.Improved lubrication effect.
4 place's oilholes (16) are arranged on transfer case housing (1), transfer-case cover (7), and its diameter is φ 2mm.Oilhole (16) draws oil by φ 2mm throttle orifice (19) from the torque converter main oil gallery, provide lubricant oil to 4 place's bearings (8) at input shaft (5) right-hand member, jack shaft (2) right-hand member, following output shaft (14) two ends simultaneously through torque converter internal oil pipe, transfer case housing (1), transfer-case cover (7) oil duct.Torque converter flows back to the lubricant oil of fuel tank (15), provides lubricant oil to being installed in input shaft (5) left end bearing on the one hand, provides lubricant oil by hole (18) to being loaded on jack shaft (2) left end bearing (8) simultaneously.
Transfer case oilhole (16) provides lubricant oil by the internal communication die cavity to the bearing (12) of the tooth clutch of independent operation simultaneously when bearing (8) fuel feeding.
The transfer case fuel tank is a torque converter gear pump fuel feeding, and the die cavity that 3 engaging gears in bottom and installation are gear (4) separates, have only bi-side, casing middle part to have oil duct to link to each other, oil behind the lubricating bearings flows to this cavity bottom through inwall, after oil-collecting is arrived to a certain degree, gear driven by the rotation that is meshing with each other carries out splash lubrication to gear, and each bearing is carried out lubrication assistant.Parts of lubricating oil is thrown on the sidewall simultaneously, flows back to fuel tank by the oil duct that is communicated with, and reaches balance up to lubricants capacity that provides and the oil mass that flows back to fuel tank.Lubricating system after this improvement has satisfied this large distance drop transfer case fully and has respectively turned round part to lubricated requirement when low speed and high speed operation.
Needle bearing (10) is used for being contained in the location of the tooth clutch output shaft (13) of tooth clutch assembly (11).
The utility model has adopted the cordwood design method.Critical piece is made up of transfer casing, driving gear, forced lubricating system and the tooth clutch assembly that can operate separately, falls apart from being 673mm, has realized that the output velocity ratio is 1 behind the upper and lower, exports velocity ratio before output of middle back and the below and be-1 transmission.
The pressure oil that large distance drop transfer case has utilized torque converter to provide carries out pressure lubrication to the various bearings in inside, rely on the bottom half oil-collecting simultaneously, the driving gear Surface of action is carried out splash lubrication, improved the lubricating system of former transfer case bearing, satisfied this large distance drop transfer case fully and when low speed and high speed operation, respectively turn round part lubricated requirement.
Large distance drop transfer case has taken into full account zero, parts interchangeability.Transfer case is inner zero, variety of components is few, and versatility, interchangeability are strong.The transfer case way of output and output quantity can be according to using needs to set.Also can be according to using needs to operate.Can also design the directly butt joint with it of other annex, as mileage and speed sensor etc.
This large distance drop transfer case drops in the normal operating range transmission shaft inclination angle, not only make equipment transmission configuration more reasonable, running is more coordinated, and can allow torque converter be with a plurality of equipment works simultaneously, simplify the structure, prolong the working life of relevant transmission part, widened the using scope of large distance drop transfer case, had considerable economic.
