Utility model content
The purpose of this utility model is to provide the back axle transmission assembly that a kind of noise is little, fuel-efficient, reduces leakage of oil risk simultaneously.
In order to achieve the above object, a kind of packaging type back axle transmission assembly that this utility model provides, including case of transmission, described case of transmission tightens together again through bolt after being fastened by left shell and right shell body, the outer wall of described left shell waist stretch out formation semicircular rear axle housing the first ring flange is installed, the outer wall of right shell body waist stretch out formation semicircular rear axle housing the second ring flange is installed, and rear axle housing installs the first ring flange and rear axle housing installs the second conglobate rear axle housing mounting flange of ring flange group, power input shaft hole and motor mounting flange it is provided with in the front portion of described left shell, the rear portion of left shell is provided with left half axle installing hole, the rear portion of right shell body is provided with right axle shaft installing hole, described left half axle installing hole and right axle shaft installing hole are coaxially disposed, left half axle installing hole and power input shaft hole are parallel to each other, it is characterized in that: at the rear portion of case of transmission, except left half axle installing hole and right axle shaft installing hole, be there is a need to the position of lubrication be all wrapped in transmission case body.
It is preferably, the antetheca of described motor mounting flange is provided with the twice annular stopper positioning boss coaxial with power input shaft hole, annular stopper positioning boss inside being positioned at positions for the installation of permanent magnetic brushless, and the annular stopper positioning boss outside being positioned at positions for the installation of asynchronous machine;Being provided with three circumferentially uniform bolt installation bases on the antetheca of described motor mounting flange for installing permanent magnetic brushless, the bolt installation base of four rectangular distributions is used for installing asynchronous machine. Case of transmission casting, can be not only used for installing permanent magnetic brushless, can be used for again installing asynchronous machine, and generalization degree is high, saves die cost.
The front and back walls of described motor mounting flange is provided with reinforcement, and on antetheca, the reinforcement of close rear axle housing mounting flange side is more intensive than the reinforcement of opposite side. Owing to motor mounting flange is big near the force rate opposite side suffered by rear axle housing mounting flange side, therefore differentiation arranges reinforcement, can proof strength, cost can be saved again.
The beneficial effects of the utility model: adopt packaging type structure, it is to avoid gear exposes, and lubricating oil has only to fill case of transmission, compare traditional structure to need to fill case of transmission and rear axle housing body, lubricating oil makes consumption greatly reduce, and decreases leakage of oil risk, reduces noise.

Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, the technical solution of the utility model is further described in detail:
Shown in Fig. 1 Fig. 4, packaging type back axle transmission assembly, including case of transmission and the drive mechanism being arranged in transmission case body.
Case of transmission tightens together again through bolt after being fastened by left shell 1 and right shell body 2. The outer wall of left shell 1 waist stretch out formation semicircular rear axle housing the first ring flange 1a is installed, the outer wall of the right shell body 2 waist semicircular rear axle housing of formation that stretches out installs the second ring flange 2a, and rear axle housing is installed the first ring flange 1a and installed the second conglobate rear axle housing mounting flange of ring flange 2a group with rear axle housing.
Being provided with power input shaft hole 1b and motor mounting flange 1c, power input shaft hole 1b in the front portion of left shell 1 and be used for installing power input shaft, motor mounting flange 1c is used for installing drive motor. It is provided with left half axle installing hole 1d at the rear portion of left shell 1, is provided with right axle shaft installing hole 2b, left half axle installing hole 1d and right axle shaft installing hole 2b at the rear portion of right shell body 2 and is coaxially disposed, be respectively used to be connected with half axle assembly, it is achieved rear-guard. Left half axle installing hole 1d and power input shaft hole 1b is parallel to each other.
At the rear portion of case of transmission, except left half axle installing hole 1d and right axle shaft installing hole 2b, be there is a need to the position of lubrication and be all wrapped in transmission case body, thus constituting packaging type back axle transmission assembly.
Preferably, the antetheca of motor mounting flange 1c is provided with the twice annular stopper positioning boss 1e coaxial with power input shaft hole 1b, annular stopper positioning boss 1e inside being positioned at positions for the installation of permanent magnetic brushless, and the annular stopper positioning boss 1e outside being positioned at positions for the installation of asynchronous machine; Being provided with three circumferentially uniform bolt installation bases on the antetheca of motor mounting flange 1c for installing permanent magnetic brushless, the bolt installation base of four rectangular distributions is used for installing asynchronous machine. Permanent magnetic brushless is generally little than the interface size of the asynchronous machine of same specification, therefore adopt the annular stopper positioning boss 1e that two size diameter do not wait for installing different motors, permanent magnetic brushless positions either directly through the annular stopper positioning boss 1e of inner side, when needing to install asynchronous machine, then the annular stopper positioning boss 1e of inner side is added by machine and remove, with the annular stopper positioning boss 1e in outside, location is installed.
It addition, be provided with reinforcement in the front and back walls of motor mounting flange 1c, and on antetheca, the reinforcement of close rear axle housing mounting flange side is more intensive than the reinforcement of opposite side.
