Abstract
The utility model relates to a shell device for a hub speed reducer of a heavy truck. The shell device comprises a hub speed reducer shell, wherein the hub speed reducer shell is fixed at the periphery of a hub through a tire bolt; the hub speed reducer shell and the hub are two independent structural members; and a plurality of O-shaped sealing rings are arranged on a joint part between the hub and the hub speed reducer shell. The shell device has the advantages that: the hub speed reducer shell and the hub are separated as two independent structural members, so the manufacturing and machining difficulty is reduced; all parts which are damaged can be changed independently, so the maintenance and use cost is reduced; one end of the hub speed reducer shell is sealed by a flange cover and a bolt, and the other end of the hub speed reducer shell is sealed by two stages of O-shaped sealing rubber rings and locked by bolts, so that the risk of leakage of lubricating oil is reduced greatly.
Description
Technical field
The utility model relates to automotive wheels side reducer guard technology field, relates in particular to a kind of heavy motor vehicle wheel reduction gear canning.
Background technology
It is in order to improve the propulsive effort of automobile, to satisfy or to revise the coupling of whole drive system propulsive effort that automobile adopts wheel reduction gear; The wheel reduction gear that is adopted at present increases the gear system of turning round for the cover reduction of speed that the needs that satisfy the whole drive system coupling increase exactly.This device is installed in the vehicle power A terminal; Alleviate the change speed gear box load; When engine ignition through power-transfer clutch, change-speed box and part-time case transmission of power to the main reduction gear of forward and backward bridge, be delivered to wheel reduction gear and wheel when driving running car from the mouth of main reduction gear again, in this course; The principle of work of wheel reduction gear be exactly the rotating speed of main reduction gear transmission and moment of torsion through its reduction of speed increase turn round after; Be delivered to wheel again,, produce than large driving force so that make wheel under the counteraction of traction.But; Existing heavy motor vehicle wheel reduction gear cage assembly mainly is made up of members such as wheel hub, end cap flange, brake wheel, bolts; This structure exists a lot of defectives, the shortcoming that for example the wheel hub processing and manufacturing of wheel reduction gear shell is difficult, installation and maintenance are inconvenient, cost is higher, lubricating oil is prone to leakage.Therefore, to above defective, need reasonably improve prior art.
The utility model content
To above defective, the utility model provides a kind of reduces the manufacturing difficulty of processing, use cost, good sealing performance heavy motor vehicle wheel reduction gear canning are safeguarded in reduction, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of heavy motor vehicle wheel reduction gear canning comprises the wheel reduction gear housing, and said wheel reduction gear housing is fixedly set in the wheel hub periphery and wheel reduction gear housing and wheel hub are divided into two individual members through tire bolt; Be positioned at wheel hub and wheel reduction gear housing junction is provided with some O-ring seals.The go side face that ends of the said wheel reduction gear housing other end is provided with end face of flange; Said O-ring seals is made up of the government rubber structure.
Compare with traditional wheel reduction gear apparatus structure, the beneficial effect of the described heavy motor vehicle wheel reduction gear of the utility model canning is: through wheel reduction gear housing and wheel hub are separated into two individual members, reduced the manufacturing difficulty of processing; Can independently change after each damage parts, reduce and safeguarded use cost; Wheel reduction gear housing one end adopts blind flange to add bolt seals, and the other end adopts sealing rubber ring sealing of secondary O shape and barrel bolt locking, greatly reduces the oil leakage risk.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the said heavy motor vehicle wheel reduction gear of a utility model embodiment canning structural representation.
Among the figure:
1, brake wheel; 2, wheel hub; 3, tire bolt; 4, wheel reduction gear housing; 5, O-ring seals; 6, end face of flange.
The specific embodiment
As shown in Figure 1; The described heavy motor vehicle wheel reduction gear of the utility model embodiment canning; Comprise wheel reduction gear housing 4; Said wheel reduction gear housing 4 is fixedly set in wheel hub 2 peripheries through tire bolt 3 and wheel hub 2 is connected through some tire bolt 3 lockings with outside brake wheel 1, thereby wheel reduction gear housing 4 and wheel hub 2 are separated into two individual members; Be positioned at wheel hub 2 and be provided with some secondary O-ring seals of being made up of the government rubber body 5 with wheel reduction gear housing 4 junctions, the go side face that ends that is positioned at wheel reduction gear housing 4 other ends is provided with end face of flange 6 and passes through the bolt mounting flange.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
