It sets.
Background technique
Steering and driving axle is in the end of offroad vehicle powertrain, and the motor torque that forerunner's transmission shaft transmits is led to
It crosses main reducing gear, differential mechanism, inside and outside semiaxis etc. and passes to driving wheel, realize that reduction of speed increases torque；Meet medial and lateral wheel with not
With the needs of rotational speed；The effect of steering is also acted as simultaneously.To meet different requirements, the main reducing gear of drive axle has
Single stage type main reducing gear and stage type main reducing gear.Medium Truck, the engineering machinery vehicle of existing configuration drum brake steering and driving axle,
Using the arragement construction of single reduction final drive, each strength of parts coefficient is high, bearing and axle shaft gear lubrication are bad, wheel hub with
Brake drum is not connected firmly with sunk screw.Solution is usually that main reducing gear is used to add planetary gear hub reduction again
The arrangement and structure optimization of device.
However, the planet carrier in brake drum, wheel hub and planetary gear train needs to be connected and fixed using dormant bolt, such as attached drawing 1
Shown, wheel hub 8, brake drum 51 need that dormant bolt 9 is first arranged at 62 three's overlapping of planet carrier, then the vehicle of single-ended screw thread are arranged
Wheel bolt 7 is attached.Accordingly, because the stability of three's overlapping is poor, it is insufficient to connect rigidity, and planet carrier 62 and wheel hub 7 are used
Dormant bolt connection is not sufficiently stable, and will lead to the problems such as hub reduction gear is easy oil leak, assembly maintenance is inconvenient, thus into one
Step influences the performance of vehicle.
Summary of the invention
The purpose of this utility model is that according to prior art shortcoming and provide that a kind of stable connection is good, ensures foot
Enough rigidity avoids oil leak, assembly from overhauling convenient a11wheel drive hub reduction driving transfer.
The purpose of this utility model is realized by following approach:
A11wheel drive hub reduction drive transfer, include transfer, brake apparatus, planet hub reduction gear and
Wheel hub, the planet hub reduction gear include sun gear, ring gear and planet carrier, and brake apparatus includes brake drum, brake drum position
In the inside of wheel hub, ring gear is fixed on the hub axle tube of transfer, and structural feature is, hub end is a kind of L
Type construction, wherein L-type bottom edge is posted by the outside on brake drum connection side, and by the wheel bolt of both ends helicitic texture a kind of into
Row connection, the connecting portion of the planet carrier are connected in the front end face of the L-type long side of hub end, the two by single ended bolt
It connects.
It is reduced to the inside of wheel hub in the edge (connection side) that brake drum is connect with wheel hub as a result, then passes through wheel spiral shell again
Bolt is attached, and planet carrier and wheel hub are also independent connection state, in this way, planet carrier is realized with brake drum and separated, respectively
It is independent to be connect with wheel hub, the connection rigidity of three is effectively improved, to avoid hub reduction gear oil leak, stable connection is good, assembly
Maintenance is convenient.
The utility model can be further specifically:
It is provided with the shaft shoulder in the middle part of the both ends helicitic texture of the wheel bolt, the brake drum is located at the shaft shoulder side, and two
End helicitic texture is connected and is locked by nut.
It is for fastening in the intermediate setting shaft shoulder of wheel bolt in order to ensure the connection rigidity between brake drum and wheel hub
Then brake drum is subject to nut check again.
It further include there are two semiaxis and universal driving device, two semiaxis and universal driving device are set to two steerings dress
Between setting, it is sequentially connected with the sun gear of planet hub reduction gear, planet carrier output end is connected on the wheel hub of rotation.
In conclusion the utility model provides a kind of a11wheel drive hub reduction driving transfer, eliminate at present
The structure that brake drum, wheel hub and planet carrier three need additional dormant bolt to be connected and fixed, wheel hub is arranged it is at L-shaped, and respectively
Brake drum and planet carrier are connected, the connection rigidity of three is effectively improved, to avoid hub reduction gear oil leak, stable connection is good,
Assembly maintenance is convenient.
Detailed description of the invention
Fig. 1 is that a11wheel drive hub reduction described in the prior art drives transfer structural schematic diagram.
Fig. 2 is that a11wheel drive hub reduction described in the utility model drives transfer structural schematic diagram.
Fig. 3 show a11wheel drive hub reduction driving transfer described in the utility model in steer drive front-axle
Structural schematic diagram.
The utility model is described further below with reference to embodiment.
Specific embodiment
Most preferred embodiment:
Referring to attached drawing 2,3, a11wheel drive hub reduction drives transfer, includes transfer 4, brake apparatus 5, row
Star-wheel side reducer 6 and wheel hub 8, the planet hub reduction gear 6 include sun gear 61, ring gear 63 and planet carrier 62, braking
Device 5 includes brake drum 51, and brake drum 51 is located at the inside of wheel hub 8, and ring gear 63 is fixed on the hub axle tube of transfer 4
On, 8 end of wheel hub is a kind of L-type construction, and wherein L-type bottom edge is posted by the outside that brake drum 51 connects side, and passes through one kind two
The wheel bolt 7 of end helicitic texture is attached, and the connecting portion of the planet carrier 62 is before the L-type long side of 8 end of wheel hub
End face, the two are attached by single ended bolt 10, as shown in Fig. 2.
Wherein wheel bolt 7 is provided with the shaft shoulder of fastening brake drum 51 in the middle part of the helicitic texture of both ends, using wheel
The connection of bolt 7 and nut check wheel hub 8 and brake drum 51, planet carrier 62 and wheel hub 8 are independently connected.
In addition, main gearbox assembly 2 is set to the big biasing in 1 left side of axle housing, for the radial torque of engine to be inputted conversion
For the output of axial torque；Two semiaxis and universal driving device 3 can will move in the hollow axle housing 1 in two sides, transfer 4
Power passes to planet wheel-side reduction device 6；Transfer 4 is set between axle housing 1 and wheel hub 8 through the pendulum of control knuckle shell 42
It moves to control the corner of wheel hub 8 and realize the steering of automobile；Two brake apparatus 5 are respectively arranged in wheel hub 8 described in 1 both ends of axle housing
Side；Two planet wheel-side reduction devices 6 are set to power train end, drive sun gear 61 by half shaft transmission gear 3, ring gear 63 is solid
Due on the hub axle tube 41 of transfer 4, on the wheel hub 8 that 62 output power of planet carrier can extremely be rotated relative to brake apparatus 5；
Two wheel hubs 8 are rotatably arranged in 1 both ends of axle housing respectively, and wheel hub 8 can connect wheel.
The characteristics of the utility model, is:
Planet wheel hem retarding mechanism small in size using light weight, intensity high ratio is big is the torque that main reducing gear is transmitted
After its reduction of speed torque increase, then it is transmitted to the wheel on wheel hub, keeps the structure of steer drive front-axle more compact.And it takes turns
Rim decelerating mechanism very easily can be packed into and take out from two sides, eliminate current brake drum, wheel hub and planet carrier three's needs
The structure that additional dormant bolt is connected and fixed, avoids hub reduction gear oil leak, and assembly maintenance is convenient.Main reducing gear, inside and outside half
The load that axis is born is greatly reduced, and such semiaxis and principal and subordinate move the part sizes such as spiral bevel gear and can further decrease ruler
It is very little, can be there are enough strength factors when design, each strength of parts is high, the service life is long.
The not described part of the utility model is same as the prior art.
