Oil Guide wall 120 is fixedly connected by fixed structure with the inner wall of accommodating chamber 112.Also, the density of Oil Guide wall 120 is small
In the density of shell 110.Oil Guide wall 120 and shell 110 are non-integral molding structure, therefore material can be different.Therefore, with biography
The integrally formed retarder casing 100 of system is compared, and in the case where structure is constant, can effectively reduce the matter of Oil Guide wall 120
Amount.In turn, the weight of retarder casing 100 and New-energy electric vehicle can be mitigated, further to realize energy-saving and emission-reduction.Therefore,
Above-mentioned New-energy electric vehicle and its energy consumption of retarder casing are smaller.
Specifically, Oil Guide wall 120 can by the metal relatively light compared with shell 110, plastics, glass fibre or other answer
Condensation material is made.If Oil Guide wall 120 is made of metal material, Oil Guide wall 120 can by the fixed structure of itself with welding,
Riveting, clamping or other fixed forms are fixed in accommodating chamber 112.If Oil Guide wall 120 is made of nonmetallic materials, fix
Structure can be outer member, and Oil Guide wall 120 is fixed on the inner wall of accommodating chamber 112 by modes such as outer member stickup, rivetings.
Specifically in the present embodiment, fixed structure is fastener.Fastener is for Oil Guide wall 120 to be removably installed in
The inner wall of accommodating chamber 112.
Therefore, when Oil Guide wall 120 because long-time use due to deform, Durchgangshohle or damage when, can by Oil Guide wall 120 disassembly simultaneously
It is replaced, consequently facilitating maintaining the normal use of retarder casing 100.
In the present embodiment, retarder casing 100 further includes sealant 140.Sealant 140 is covered to be carried on the back in Oil Guide wall 120
To the surface of input unit 115.
By the way that sealant 140 is arranged, can by seal oil in Oil Guide chamber 122, and then can effectively avoid lubricating oil from
Gap leakage between 112 inner wall of Oil Guide wall 120 and accommodating chamber and the normal work for influencing New-energy electric vehicle.Specifically,
Sealant 140 can be sealant layer, is also possible to cover in the sealing element on 120 surface of Oil Guide wall, only need to ensure that sealant can
By seal oil in Oil Guide chamber 122.
In the present embodiment, retarder casing 100 further includes the reinforcing rib 130 for accommodating and being fixed in accommodating chamber 112.Add
The both ends of strengthening tendons 130 are abutted with Oil Guide wall 120 backwards to the surface of input unit 115 and the inner wall of accommodating chamber 122 respectively.
By the way that reinforcing rib 130 is arranged, Oil Guide wall 120 can be securely mounted to the inner wall of shell 110.Work as reducer shell
100 when shaking at work or when the impact force of lubricating oil is excessive, and reinforcing rib 130 can play good branch to Oil Guide wall 120
Support effect, and then can effectively avoid the deformation of Oil Guide wall 120 or fall off from the inner wall of shell 110, consequently facilitating maintaining retarder machine
The normal work of shell 100.
In the present embodiment, retarder casing 100 further includes fixing piece 150.The outer wall of procapsid 113 and back casing 114
Opposite position is respectively arranged with boss 152.Fixation hole 154 is offered on boss 152, fixing piece 150 is arranged in fixation hole 154
It is interior.
By the way that fixing piece 150 is arranged, procapsid 113 is removably installed in back casing 114.When retarder casing 100
When internal element failure, procapsid 113 can be dismantled, to facilitate operation personnel to being examined inside shell 110
It surveys and repairs.
In the present embodiment, retarder casing 100 further includes reinforcing rod 170 and is set to input unit 115, driving section 116
And the annular convex platform 160 of output section 117.Surface of the both ends of reinforcing rod 170 respectively with Oil Guide wall 120 and annular convex platform 160 is supported
It connects.
In New-energy electric vehicle, input shaft, jackshaft and differential output shaft respectively with input unit 115, driving section
116 and 117 position of output section it is corresponding, and be arranged in the corresponding annular convex platform 160 in position therewith respectively.
Therefore, by the way that annular convex platform 160 is arranged, input shaft, jackshaft and differential output shaft can be stably installed at
Retarder casing 100, consequently facilitating maintaining the normal work of retarder casing 100.And reinforcing rod 170 plays annular convex platform 160
Supporting role is stably fixed to shell 110 convenient for annular convex platform 160.
Further, the side wall of annular convex platform 160 offers oil discharge outlet 180, and oil discharge outlet 180 is connected to Oil Guide chamber 122.
By be arranged oil discharge outlet 180, into the lubricating oil in Oil Guide chamber 122 can from oil discharge outlet 180 enter input unit 115,
Driving section 116 and output section 117, to realize the lubricating action to 100 internal element of retarder casing.
Above-mentioned New-energy electric vehicle and its retarder casing 100, the edge of Oil Guide wall 120 and the inner wall of accommodating chamber 112
It abuts, to form Oil Guide chamber 122, realizes its Oil Guide function.Oil Guide wall 120 and shell 110 are non-integral molding structure, therefore material
Matter can be different.Wherein, the density of Oil Guide wall 120 is less than the density of shell 100.Therefore, with traditional integrally formed deceleration
Device casing 100 is compared, and in the case where structure is constant, can effectively reduce the quality of Oil Guide wall 120.In turn, can further subtract
The weight of light retarder casing 100 and New-energy electric vehicle, to realize energy-saving and emission-reduction.Therefore, above-mentioned New-energy electric vehicle
And its energy consumption of retarder casing 100 is smaller.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
