Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "center", "length", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

In the description of the present invention, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "fixed" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in FIG. 1, the utility model discloses a take big torque transmission of rear suspension and booster structure, this derailleur is including the derailleur body 3 that has the casing, along the direction that the car went, the casing divide into preceding shell 1, mesochite 4 and backshell triplex from preceding backward in proper order. The outer side of the middle shell 4 is connected with two whole vehicle rear suspensions 6 through screws, the two whole vehicle rear suspensions are symmetrically arranged about the central line of the middle shell, and the transmission is fixedly connected with the vehicle frame 7 through the whole vehicle rear suspensions. One end of the transmission front shell is provided with an oil pump and line assembly 9 for providing lubrication to the interior of the transmission body 3. An input shaft 8 positioned at the front end of the transmission in the transmission body 3 is connected with an engine; the outside of mesochite 4 is provided with booster 2, and this booster is used for the supplementary operating force that shifts, reduces to shift. The one end relative with input shaft 8 place end is provided with scope in the derailleur body 3 and keeps off a case subassembly 5, and the backshell is the shell body that the scope kept off case subassembly 5.

This derailleur has satisfied the matching requirement of whole car, and the suspension is installed in derailleur mesochite department behind the whole car, makes whole car driving system arrange more rationally, can effectively improve the noise and the vibration of whole car, especially noise and vibration that the explosion pressure of engine arouses, and the booster adopts pneumatics to shift simultaneously, has alleviateed driver's the power of shifting, has promoted the driving comfort of whole car greatly.

The technical features of the present invention that are not described in the present invention can be realized by or using the prior art, and are not described herein again, and certainly, the above description is not limited to the limitations of the present invention, the present invention is not limited to the above embodiments, and the changes, modifications, additions or replacements made by the technical personnel in the field in the essential scope of the present invention should also belong to the protection scope of the present invention.
