Technical field
The utility model is related to the design of case of transmission, for it is a kind of meet it is matched under the premise of, consider lightweight, general
Property etc., so that product is optimal economic performance；Specially a kind of intensity is high, good airproof performance, and the left and right that matches of good manufacturability takes
The lightweight speed changer middle casing of power device.
Background technology
With China market expanding economy, the continuous enhancing of overall national strength increases the dynamics of investment to infrastructure.
The especially implementation of development of the West Regions and male Anxin area construction strategy, water power, mining industry, oil field, highway, railway, urban transportation and
Many industries such as environment-friendly engineering all increase the demand to special purpose vehicle, it is desirable that self-unloading, which may be implemented, in vehicle, shines water, cement stirs
The various demands such as mix, freeze, because the different working condition requirements of automobile need to match different power takeoffs, to meet vehicle kind
The numerous chassis structures of class.
The fast development of automobile industry requires special-purpose vehicle that various functional requirements may be implemented, each in face of vehicle
When the chassis arrangement of kind various kinds, it is desirable that speed changer itself can carry a variety of power takeoffs.Existing automobile market is to super simultaneously
The attention increasingly for the problems such as carrying and discharging and the requirement of Automobile Design modularization and versatility, case of transmission is in exploitation
It needs to fully consider that shell dead weight must be low as possible under conditions of ensureing that casing rigidity is enough, while can match existing
The other parts of HW90510 speed changers.
Invention content
The utility model is to solve current HW90510 speed changers to estimate one's own ability heavier technical problem, and a left side can be matched by providing one kind
The lightweight speed changer middle casing of right power takeoff.
The utility model adopts the following technical scheme that realization：
A kind of lightweight speed changer middle casing matching left and right power takeoff is provided in the speed changer middle casing left and right
Power taking window, left and right power taking window are arranged at the most upper limit position on shell in the transmission；The left and right power taking window is
Raised type structure, outer male structure generally engraved structure.
Because HW90510 speed changers are double intermediate structures, shell described in the utility model can be from the left and right of speed changer two
Root jackshaft power taking keeps transmission dependency structure arrangement in vehicle chassis more reasonable, compact.
Middle casing is designed as two power takeoff windows by the utility model, in the premise for the transmission space for meeting speed changer
Under, keep the position of left and right power takeoff window high as possible, can so improve the minimum road clearance of vehicle, provides the logical of vehicle
Cross performance.To improve the casing rigidity of speed changer, fully considers that loss of weight measure reduces dead weight in terms of housing design, keep
The highly versatile of speed changer.
The utility model is in order to promote in speed changer aluminium the main Mechanical of shell and speed changer in actual use
To the performance of different power takeoff demands.
Achievable function is：
A. the overall weight of speed changer is reduced；
B. the versatility of shell in speed changer is kept；
C. the integral strength of speed changer middle casing is improved；
D. left and right power takeoff can be carried.

Specific implementation mode
A kind of lightweight speed changer middle casing matching left and right power takeoff, which is characterized in that the speed changer middle casing
On be provided with left and right power taking window, the setting of left and right power taking window is in the transmission at the most upper limit position on shell；It is described left and right
Power taking window is raised type structure, outer male structure generally engraved structure.The outside of left and right power taking window and middle casing outer wall
Between be connected by reinforcing rib 2.
As shown in Fig. 1 ~ 3, it is assembled into the structural schematic diagram after speed changer entirety for the utility model, as shown in figure 4, figure
A in 4 is the structural schematic diagram of oldState middle casing, and power taking window is substantially close to surface of shell；B in Fig. 4 is shown
The structural schematic diagram of new state middle casing, power taking window protrude from surface of shell completely, and outside the outside of protrusion part and shell
Reinforcing rib is connected between side.A in Fig. 5 is old shell, and the b in Fig. 5 is new shell, new and old shell overall structure basic one
It causes, can directly exchange, maintain the versatility of speed changer.As shown in fig. 6, for the internal structure of shell described in the utility model
Schematic diagram, it can be seen that power taking window interior is Openworks shape structure；It is the external structure schematic diagram of power taking window as shown in Figure 7,
Power taking window integrally protrudes from surface of shell；In conjunction with Fig. 6 and 7 it is found that being provided with corresponding left and right power taking in speed changer middle casing
Mouthful, the outer edge of power taking mouth extends to form an extended segment for being rectangle opening outward, and then constitutes power taking window；Then
Without any attached inside extension, for whole engraved structure, inner cavity Lightened structure is constituted；It is connected on the outer wall of extension
There is reinforcing rib.
As shown in Figure 6,7, in figure 6 the left power takeoff window of shell and the right power takeoff window of Fig. 7 middle casings because of entirety
The needs of arrangement protrude outward, will be whole inside protrusion under conditions of ensureing certain wall thickness to ensure that shell dead weight is small
Hollow out, while to prevent the mechanical strength of loss of weight back casing from declining, in the inside and outside stress concentration of shell power takeoff window
Position be designed with reinforcing rib, not only improved the mechanical strength after HW90510 speed changer middle casings installation power takeoff, but also effective
Reduce the weight of HW90510 speed changer entirety.About 50 yuan of expense cost is also saved simultaneously.
As shown in figure 8, ensureing associated vehicle regulation vehicle frame outer width maximum 865mm, inner width 735mm and vehicle requirement speed change
Device outermost and frame inside safe distance be >=25mm under the premise of, can calculate：Speed changer outermost distance center is minimum
For 735 ÷ 2-25=342.5mm；The spacing on power takeoff and ground is 247mm, can so improve minimum liftoff of vehicle
Gap, provide vehicle passes through performance.
