Technical Field

[0001] This utility model belongs to the field of transmission technology, and relates to transmission bracket connecting plates, specifically a transmission bracket connecting plate with a positioning pin. Background Technology

[0002] As the medium and heavy-duty truck industry sees an increasing variety of products and personalized customization becomes more common, product versatility is gradually decreasing, leading to a growing demand for personalized products and various components. With the continuous iteration and updates of vehicle specifications, the product specifications matched by OEMs vary significantly, resulting in an increasing need to utilize relevant connection holes in the transmission.

[0003] When matching different models or different manufacturers' transmissions, the different structures, sizes and connection holes of the transmissions themselves can cause the OEM to have various deformed brackets when matching different transmissions, resulting in a wide variety of control cable brackets and increasing manufacturing, procurement and management costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transmission bracket connecting plate with a positioning pin, so as to solve the technical problem that the same type of control cable bracket is difficult to match different models of transmissions at the same time.

[0012] Specifically, the connecting plate body includes an integrally formed bracket connecting part and a housing connecting part. The bracket connecting part is provided with a first bolt mounting hole and a bracket positioning pin; the housing connecting part is provided with a second bolt mounting hole.

[0013] Preferably, the top surface of the bracket connecting part and the top surface of the housing connecting part are located in the same plane, the thickness of the bracket connecting part is less than the thickness of the housing connecting part, and the bracket connecting part, the control cable bracket and the heavy truck transmission housing can be fitted together in sequence; the housing connecting part can fit into the heavy truck transmission housing.

[0014] Preferably, the stepped surface between the bracket connecting part and the housing connecting part is the secondary positioning surface of the bracket, and the secondary positioning surface of the bracket is perpendicular to the bracket connecting part.

[0015] Preferably, the bracket connection part has a sloping contact surface near the edge of the first bolt mounting hole, and the sloping contact surface can be in contact with the vertical plate fixing slope of the operating pull wire bracket.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] (I) In this utility model, the bracket connecting plate with positioning pin realizes the requirement that the control cable bracket can be matched with different gearbox housings, reducing the types of different deformable parts; at the same time, the bracket connecting plate with positioning pin has a simple structure, low processing cost, and brings a lot of convenience for compatibility matching, and is highly operable.

[0018] (II) The device in this utility model enables the control cable bracket corresponding to the light truck transmission housing to be fixed to the heavy truck transmission housing by the first fixing bolt, the second fixing bolt and the positioning pin, which increases the versatility of the control cable bracket; at the same time, after vehicle installation test, the effect is good and meets the usage requirements.

[0019] (III) In this utility model, at the mating end face of the transmission bracket connecting plate with positioning pin and the control cable bracket, the material of the connecting plate body is removed according to the shape of the control cable bracket to form a second positioning surface, which can perform secondary positioning of the control cable bracket.

[0020] (IV) In this utility model, part of the material of the connecting plate body is removed from the gearbox bracket connecting plate with positioning pin at the rear end of the first bolt mounting hole to form a sloping contact surface, which can avoid the interference of the vertical plate fixing slope of the control cable bracket on the installation of the connecting plate body.

[0030] It should be noted that, unless otherwise specified, all equipment and components in this utility model are based on existing technologies. For example, the heavy-duty truck transmission uses a known heavy-duty truck transmission, and the first fixing bolt uses a known first fixing bolt.

[0031] The technical concept of this utility model is as follows: When the control cable bracket corresponding to the light truck transmission housing is assembled on the heavy truck transmission housing, because the size of the heavy truck transmission housing is larger than that of the light truck transmission housing, the two fixing bolt mounting holes of the control cable bracket cannot be fully matched with the mounting bolt mounting holes on the heavy truck transmission housing in the vertical direction, resulting in the control cable bracket corresponding to the light truck transmission housing being unable to be assembled on the heavy truck transmission housing.

[0032] In this invention, the OXYZ coordinate system is a three-dimensional rectangular coordinate system, with the X-axis pointing horizontally to the right; the Y-axis pointing vertically to the rear; and the Z-axis pointing vertically upwards.
