Abstract
A speed reduction transfer case is mainly composed of an input shaft component, a hydraulic pump shaft component, a motor shaft component, a case body component and a lubrication component. A driving gear of the input shaft component is respectively meshed with five driven gears which are distributed in a circle around the driving gear and belong to the hydraulic pump shaft component and the motor shaft component respectively, wherein a hydraulic pump shaft of the hydraulic pump shaft component is connected with two hydraulic pumps respectively, and a motor shaft of the motor shaft component is connected with a generator and a hydraulic pump respectively so that a power transmission mechanism with one middle input driving ten outputs is formed. A shaft end of the input shaft component is connected with an input flange which is fixed axially by a pressing plate, and an oil slinger is arranged on the side of the shaft end of the input shaft component. The speed reduction transfer case has the advantages of being compact in structure, small in volume, light in weight, high in usage reliability and the like.
Description
Technical field
The utility model relates to the deceleration transfer case that a kind of power transmission is used.
Background technique
In the prior art, the structure of deceleration transfer case mainly is made up of input shaft parts, hydraulic pump shaft parts, motor shaft parts, box part and lubricating component etc.Power drives the input shaft parts by input flange and rotates, and driving gear is meshed with driven gear, drives hydraulic pump shaft parts and motor shaft parts and rotates.Oil hydraulic pump is connected with hydraulic pump shaft by coupling.The transfer speed reducer of said structure, hydraulic pump shaft, motor shaft and input shaft horizontal arrangement, a gear-box just needs a plurality of hydraulic pump shafts if connect a plurality of oil hydraulic pumps, its horizontal arrangement just makes that the speed reducer casing is oversize, all influential to making and installing, thus limited the connection number of oil hydraulic pump.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of can connection oil hydraulic pump as much as possible, can make speed reducer accomplish the deceleration transfer case of compact structure again.
The purpose of this utility model is finished by following technical solution, it mainly is made up of input shaft parts, hydraulic pump shaft parts, motor shaft parts, box part, lubricating component, the driving gear of described input shaft parts be arranged in five driven gears that belong to hydraulic pump shaft parts and motor shaft parts that make a circle in its week and mesh respectively, wherein respectively connect two oil hydraulic pumps on the hydraulic pump shaft of hydraulic pump shaft parts, respectively connect a generator and an oil hydraulic pump on the motor shaft of motor shaft parts, constitute the power-transmitting unit of a middle input, ten outputs of drive.
The axle head of described input shaft parts is connected with input flange, and a pressing plate is with the input flange axial restraint, and the shaft end side of input shaft parts is provided with disc.
The hydraulic pump shaft two axial ends of described hydraulic pump shaft parts adopts embedded inner spline housing structure, and with circlip for hole with its axial restraint, circumferentially fixing with key, and directly connect oil hydraulic pump.
Hydraulic pump shaft described in the utility model and the even circumference of motor shaft parts branch are around input shaft, have four hydraulic pump shaft output shafts and a motor shaft output shaft, two spindle noses of each hydraulic pump shaft can connect two oil hydraulic pumps, spindle nose of motor shaft can connect generator, and the other end can connect oil hydraulic pump.By the input shaft input of centre, both sides output drives oil hydraulic pump and generator rotates, on one side five oil hydraulic pumps, four oil hydraulic pumps and a generator on one side.Optimized housing structure so greatly, reduced the volume of transfer speed reducer, made whole speed reducer in light weight, volume is little, and working stability is reliable.
The embedded inner spline housing in spindle nose two ends of described hydraulic pump shaft, oil hydraulic pump is directly installed on the end cap, and its spindle nose inserts in the inner spline housing, the coupling in the middle of having saved.And oil pump pastes installation mutually with end cap, saved the Sealing of spindle nose.Thereby make more compact structure, install more convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Fig. 1,2, the utility model mainly is made up of input shaft parts 1, hydraulic pump shaft parts 2, motor shaft parts 3, box part 4, lubricating component 5.The driving gear 7 of described input shaft parts 1 be arranged in five driven gears 8 that belong to hydraulic pump shaft parts 2 and motor shaft parts 3 that make a circle in its week and mesh respectively, wherein respectively connect two oil hydraulic pumps 9 on the hydraulic pump shaft of hydraulic pump shaft parts, respectively connect a generator and an oil hydraulic pump on the motor shaft of motor shaft parts, constitute the power-transmitting unit of a middle input, ten outputs of drive.
The axle head of described input shaft parts 1 is connected with input flange 6, one pressing plates 11 with input flange 6 axial restraints, and the shaft end side of input shaft parts 1 is provided with disc 12.
The hydraulic pump shaft two axial ends of described hydraulic pump shaft parts adopts embedded inner spline housing 13 structures, and with circlip for hole 14 that its axial restraint, usefulness key 15 is circumferentially fixing, and directly connects oil hydraulic pump 9.
Power drives flange 6 input shaft parts 1 by the diesel engine input and rotates, and the middle driving gear 7 and five driven gears 8 that make a circle in week are meshed, and drives hydraulic pump shaft 2 and 3 rotations of motor shaft parts; Every hydraulic pump shaft can connect two oil hydraulic pumps 9, and motor shaft can connect a generator and an oil hydraulic pump, and a middle input can drive ten outputs altogether.
The utility model structurally has many unique distinctions: middle input, the pattern of output circumference makes an input can drive ten outputs.And accomplished compact structure, the volume of speed reducer is little, and is in light weight, and simple structure just can realize one-to-multiple function.Adopt the embedded inner spline housing structure of output shaft in output shaft and being connected of oil hydraulic pump, realized the direct-connected of oil hydraulic pump and axle.Not only simplified linkage structure, saved coupling, also saved structures such as output axle head oil sealing, made structure simpler, more reliable, and save coupling, also make the length of input shaft can be shorter, guaranteed the rigidity of input shaft.
