Description

Technical Field

[0001] The present invention relates to the technical field of gearboxes, and specifically to a combined gearbox for automobiles. Background Art

[0002] A gearbox is a gearbox that changes the transmission ratio and the direction of motion, and is located between the clutch connection body and the central transmission. Its main functions are: to change the driving force and the driving speed of the vehicle under the condition that the engine speed and torque remain unchanged; according to the transmission type, the gear-type gearbox can be divided into three types: two-shaft type, three-shaft type, and combined type. The two-shaft type has two main shafts (excluding the reverse gear shaft) and only undergoes a pair of gear reductions. The three-shaft type has three main shafts and undergoes two pairs of gear reductions. The combined type is composed of two gearboxes connected in series or in parallel to obtain more gears with fewer gears. However, when the gearbox is working, it is easy to affect the speed change due to the deviation of the connection position, and when the bottom of the gearbox contacts the vehicle, it is easy to increase the difficulty of the overall vehicle layout, making it difficult to avoid slipping during speed change and resulting in insufficient power during vehicle operation.

[0003] In summary, when the gearbox is working, it is easy to affect the speed change due to the deviation of the connection position, and when the bottom of the gearbox contacts the vehicle, it is easy to increase the difficulty of the overall vehicle layout, making it difficult to avoid slipping during speed change and resulting in insufficient power during vehicle operation. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a combined gearbox for automobiles, which solves the problems that when the gearbox is working, it is easy to affect the speed change due to the deviation of the connection position, and when the bottom of the gearbox contacts the vehicle, it is easy to increase the difficulty of the overall vehicle layout, making it difficult to avoid slipping during speed change and resulting in insufficient power during vehicle operation.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A combined gearbox for an automobile, including a fixed disk, the top of the fixed disk is fixedly connected with an installation device, the middle position at the top of the installation device is fixedly connected with a connection box, the bottom of the connection box penetrates through the installation device and extends to the inside of the installation device, both sides of the front of the installation device are fixedly connected with fixed columns, and one end of the fixed column away from the installation device is fixedly connected with a limiting ring. Through the limiting ring, the connection position of the installation device can be guided, which is convenient for improving the tightness when the installation device is connected to other components, making it not easy for the connection position to slip when the gearbox works as a whole, thereby improving the convenience during gear shifting. Moreover, the tight fit between the limiting ring and the fixed column is beneficial to increasing the moving range of the limiting ring, thereby improving the stability of the limiting ring during operation. The bottom of the outer wall on the right side of the installation device is fixedly connected with an assembly frame. By cooperating with the fixed disk through the assembly frame, the installation device is supported, thereby increasing the stability of the installation device during operation, effectively reducing the overall shaking generated when the gearbox works, and the tight fit between the assembly frame and the installation device makes there be a certain amount of moving space between the installation device and the assembly frame, which is convenient for increasing the fastening effect of the installation device.

[0006] The installation device includes a gearbox housing. The bottom of the left inner wall of the gearbox housing is fixedly connected with a liquid storage tank. The bottom of the outer wall on the right side of the liquid storage tank is communicated with a circulation pipeline. Through the circulation pipeline, the liquid circulates under the pressure of the liquid storage tank with the operation of the gearbox, so that the liquid inside the circulation pipeline can take away the heat generated by the components inside the gearbox housing during operation, thereby ensuring the constancy of the temperature inside the gearbox housing, effectively avoiding damage to the components caused by the long-term operation of the whole gearbox, and the circulation pipeline can support the liquid storage tank, thereby increasing the stability of the liquid storage tank after installation. The middle part of the front of the gearbox housing is fixedly connected with a brake sleeve. Through the contact between the brake sleeve and the gearbox housing, the gearbox housing can be fixed to the brake sleeve, making it not easy for the brake sleeve to slide down and squeeze the circulation pipeline during operation. Moreover, the contact between the brake sleeve and the connection device is convenient for downward fixation, thereby increasing the stability of the gearbox during operation. At the same time, the connection device can seal the bottom of the gearbox housing, which is convenient for cooperating with the brake sleeve to protect the working range of the circulation pipeline. The back of the brake sleeve penetrates through the gearbox housing and extends to the outside of the gearbox housing. The two inner walls of the brake sleeve are rotatably connected with a transmission device. The top of the two inner walls of the gearbox housing is fixedly connected with a connection device.

[0007] Preferably, the connecting device includes a connecting piece which cooperates with the sealing abutment plate to facilitate the extrusion of the linkage device, thereby providing guidance for the connection of the power component of the linkage device. At the same time, the connection of the connecting piece to the components helps to ensure that there are no deviations at the contact positions of the components, which may affect the speed change operation, and thus reduces the installation difficulty of the gearbox on the vehicle. The connecting piece can ensure that there is enough space for the placement of components between the positioning blocking frame and the sealing abutment plate. The outer wall on the right side of the connecting piece is fixedly connected with a positioning blocking frame. The space between the positioning blocking frame and the cooler is used for the flow of air. At the same time, the positioning blocking frame can divide the air flow, facilitating the acceleration of the air flow during cooling, and further improving the rate of temperature reduction inside the gearbox. The positioning blocking frame can filter the discharged air flow, preventing the flow position of the air flow from being blocked by impurities, and the contact between the positioning blocking frame and the connecting piece can clean the outside of the positioning blocking frame to reduce the adhesion of impurities. The cooler is fixedly connected to the left side of the bottom of the positioning blocking frame.

By contacting the boost sleeve through the transfer compression sleeve, it is convenient to support the boost sleeve, thereby enhancing the strength of the boost sleeve itself, preventing excessive wear at the position where the boost sleeve contacts the transmission shaft and resulting in damage and scratches on the surface of the transmission shaft, and further extending the service life of the boost sleeve. The pressure on the surface of the transfer compression sleeve improves the stability when the transmission shaft rotates. The two inner walls of the transfer compression sleeve are rotatably connected to the boost sleeve. Through the boost sleeve, the rotating transmission shaft can be rotated, which is convenient for reducing the friction force received when the transmission shaft rotates, and thus extends the service life of the transmission shaft. When the boost sleeve is tightened by the transfer compression sleeve, it approaches the boost sleeve and squeezes it, causing the rotation speed of the boosting member inside the boost sleeve to decrease, facilitating the decrease in the rotation speed of the transmission shaft, and the area where the boost sleeve approaches the transmission shaft increases, causing the rotation speed of the transmission shaft to slow down. The two sides of the boost sleeve penetrate through the transfer compression sleeve and extend to the outside of the transfer compression sleeve. The two inner walls of the boost sleeve are rotatably connected to the transmission shaft. The right end of the transmission shaft is rotatably connected to a clutch connection body. Through the rotation of the clutch connection body driven by the transmission shaft, the clutch connection body can ensure the fastening of the contact position of the components, effectively avoiding loosening when the components connected by the clutch connection body rotate and resulting in a decrease in the power during component rotation. Moreover, the clutch connection body can position the transmission shaft, which is beneficial for the clutch connection body to limit the distance that the transmission shaft extends out of the boost sleeve.

The middle part of the right outer wall of the linkage body penetrates through the placement frame and extends to the outside of the placement frame. At the top of both outer walls of the linkage body, there are rotatably connected tightening frames. By closely fitting the tightening frames with the placement frame, the tightening frames support the placement frame, effectively ensuring the stability of the placement frame, preventing the surface of the placement frame from being prone to bending or cracks during long-term use. And the tightening frames are in contact with the linkage body, which can position the connection position of the linkage body, conducive to increasing the rotation smoothness of the linkage body after installation, and avoiding the influence of the rotation of the linkage body on the tightening force of the tightening frames. On the left outer wall of the placement frame, there is a fixedly connected fixing plate. By closely fitting the fixing plate with the placement frame, the fixing plate can fix the placement frame, thereby increasing the fastening when installing the internal components of the placement frame, and further increasing the tightness when the fixing plate is fixed, which is conducive to enhancing the strength of the fixing plate itself, preventing the position of the fixing plate far from the placement frame from breaking and causing the placement frame to shake and affect the rotation of the linkage body.

[0010] Preferably, the adjusting device includes an adjusting bracket which contacts with the sealing sleeve through the adjusting bracket, facilitating the adjusting bracket to support the sealing sleeve, effectively avoiding the situation that the adjusting bracket shakes due to the power during the rotation of the variable-speed connecting column. The adjusting bracket positions the variable-speed connecting column, enabling the variable-speed connecting column to rotate smoothly on the adjusting bracket, which is beneficial to reducing the phenomenon that the variable-speed connecting column cannot be accurately installed during the replacement process after being damaged. A sealing sleeve is fixedly connected to the outer wall on the right side of the adjusting bracket. Through the sealing sleeve, pressure can be exerted on the reinforcing ring, and there is an auxiliary part inside the sealing sleeve to position the installation position of the reinforcing ring, enabling the auxiliary part to increase the contact surface of the conversion sleeve, thereby reducing the internal moving space of the sealing sleeve, effectively increasing the contact area of each component inside the sealing sleeve, facilitating the use of the auxiliary part to support the conversion sleeve at multiple positions, and being beneficial to ensuring the adjustment of the variable-speed connecting column by the conversion sleeve. A reinforcing ring is fixedly connected to the left side at the top of the inner cavity of the sealing sleeve. The right side of the reinforcing ring away from the sealing sleeve is fixedly connected to a conversion sleeve. Through the close fit of the conversion sleeve and the reinforcing ring, the conversion sleeve can support the inside of the sealing sleeve, thereby increasing the sealing effect of the sealing sleeve and improving the stability of the conversion sleeve at the same time, preventing the change in the speed of the variable-speed connecting column from affecting the stability of the conversion sleeve inside the sealing sleeve. And under the pressing of the reinforcing ring, the conversion sleeve is further ensured to be fastened after installation, avoiding the situation that the conversion sleeve tilts and causes the variable-speed connecting column to be stuck. The position of the conversion sleeve away from the reinforcing ring is fixedly connected to the sealing sleeve, and a variable-speed connecting column is rotatably connected to the position of the conversion sleeve close to the reinforcing ring.

[0016] Step 2: The liquid circulates through the circulation cavity generated by the liquid storage tank and the circulation pipeline. As the liquid approaches the brake sleeve while flowing in the circulation pipeline, the brake sleeve is rotationally connected to the transmission device, and the liquid storage tank is fixedly connected to the connecting device, so that the liquid storage tank supports the connecting device;

[0017] Step 3: Use a cooler to cool the gearbox while it is working, fix the positioning blocking frame and the connecting piece so that the positioning blocking frame and the connecting piece form a space for placing the cooler, and fix the sealing plate and the linkage device;

[0018] Step 4: When the transmission shaft is subjected to the power of the automobile, the clutch connection body is driven to rotate, and when the transmission shaft rotates inside the boost sleeve, the boost sleeve is driven to rotate together, and the boost sleeve is rotatably connected with the adapter compression sleeve, so that the outside of the adapter compression sleeve is subjected to pressure to squeeze the boost sleeve;

[0021] The present invention provides a one-piece gearbox for an automobile, which has the following beneficial effects:

[0022] (I) The one-piece gearbox for automobile is provided with a limit ring, a fixing column, a circulation pipe and a liquid storage tank. The limit ring can be used to guide the connection position of the mounting device, so as to improve the tightness of the mounting device when connected with other components, thereby improving the stability of the limit ring when working. The circulation pipe circulates the liquid under the pressure of the liquid storage tank as the gearbox works, so that the liquid inside the circulation pipe can take away the heat generated by the internal components of the gearbox housing when working, thereby ensuring the constant temperature inside the gearbox housing, effectively avoiding damage to the components caused by the long-term operation of the entire gearbox, and protecting the working range of the circulation pipe.

[0023] (ii) The one-piece gearbox for automobiles is tightly fitted with the conversion sleeve and the reinforcement ring, so that the conversion sleeve can support the inside of the sealing sleeve, thereby increasing the sealing effect of the sealing sleeve, further ensuring the tightness of the conversion sleeve after installation, and avoiding the conversion sleeve from tilting and causing the speed change connecting column to get stuck. The sealing sleeve can apply pressure to the reinforcement ring, thereby reducing the movable space inside the sealing sleeve, effectively increasing the contact area of ​​the various components inside the sealing sleeve, and is conducive to ensuring the adjustment of the conversion sleeve on the speed change connecting column.

[0024] (III) The one-piece gearbox for automobile is closely fitted with the placing frame by the tightening frame, so that the tightening frame supports the placing frame, effectively ensuring the stability of the placing frame, preventing the placing frame from bending or cracking when it is used for a long time, and facilitating the smooth rotation of the linkage body after installation, avoiding the influence of the rotation of the linkage body on the tightening force of the tightening frame, and the close fit between the fixing plate and the placing frame increases the tightness of the fixing plate when it is fixed, which is conducive to enhancing the strength of the fixing plate itself.

[0025] (IV) The one-piece gearbox for automobiles can rotate the rotating transmission shaft through the booster sleeve, which is convenient for reducing the friction force on the transmission shaft when rotating, thereby extending the service life of the transmission shaft. The area of ​​the booster sleeve close to the transmission shaft is increased, which slows down the rotation speed of the transmission shaft. The contact between the adapter clamping sleeve and the booster sleeve is convenient for supporting the booster sleeve, thereby enhancing the strength of the booster sleeve itself and preventing the booster sleeve from being worn too much at the position where it contacts the transmission shaft, resulting in scratches on the surface of the transmission shaft.

[0026] (V) The one-piece gearbox for automobiles circulates air through the space between the positioning blocking frame and the cooler, further improving the rate of temperature reduction inside the gearbox. The positioning blocking frame can filter the discharged airflow, so that the flow position of the airflow is not easily blocked by impurities and affects the flow. The sealing plate fits tightly with the linkage device, so that the sealing plate can support the linkage device when it is fixed, thereby improving the stability of the linkage device during operation, which is beneficial to reducing the situation of insufficient power during speed change operation.

[0027] (VI) The one-piece gearbox for automobile is in contact with the sealing sleeve by adjusting the bracket, so that the adjusting bracket supports the sealing sleeve, effectively avoiding the shaking of the adjusting bracket due to the power when the speed change connecting column rotates. The adjusting bracket positions the speed change connecting column, which is beneficial to reducing the phenomenon that the speed change connecting column cannot be accurately installed during replacement after it is damaged. The clutch connecting body rotates under the drive shaft, effectively avoiding the loosening of the connecting parts of the clutch connecting body during rotation, which causes the power reduction when the parts rotate.

[0028] (VII). The integrated gearbox for automobiles can support the linkage body through the mounting parts, enabling the mounting parts to transmit the power of the linkage body, thereby increasing the evenness of the force on the linkage body and effectively avoiding the sudden stop of the linkage body during rotation due to insufficient force. The connecting part cooperates with the sealing bottom plate to facilitate the extrusion of the linkage device, thus providing guidance for the connection of the power component of the linkage device. The connecting part can ensure that there is sufficient space for placing the moving parts between the positioning blocking frame and the sealing bottom plate. Description of the Drawings

The adjusting bracket 95 positions the variable-speed connecting column 93, enabling the variable-speed connecting column 93 to rotate smoothly on the adjusting bracket 95, which is beneficial to reducing the phenomenon that the variable-speed connecting column 93 cannot be accurately installed during the replacement process after being damaged. The right outer wall of the adjusting bracket 95 is fixedly connected with a sealing sleeve 91. Through the sealing sleeve 91, pressure can be exerted on the reinforcing ring 94, and there is an auxiliary part inside the sealing sleeve 91 to position the installation position of the reinforcing ring 94, enabling the auxiliary part to increase the contact surface of the conversion sleeve 92, thereby reducing the internal moving space of the sealing sleeve 91, effectively increasing the contact area of each component inside the sealing sleeve 91, facilitating the multi-position support of the conversion sleeve 92 by the auxiliary part, and being beneficial to ensuring the adjustment of the conversion sleeve 92 to the variable-speed connecting column 93. The left side of the top of the inner cavity of the sealing sleeve 91 is fixedly connected with a reinforcing ring 94. The right side of the reinforcing ring 94 away from the sealing sleeve 91 is fixedly connected with a conversion sleeve 92. Through the tight fit of the conversion sleeve 92 and the reinforcing ring 94, the conversion sleeve 92 can support the inside of the sealing sleeve 91, thereby increasing the sealing effect of the sealing sleeve 91 and at the same time improving the stability of the conversion sleeve 92, preventing the conversion sleeve 92 from being affected by the speed change of the variable-speed connecting column 93 in the sealing sleeve 91 and affecting the stability of the conversion sleeve 92. And under the pressing of the reinforcing ring 94, the conversion sleeve 92 is further ensured to be fastened after installation, avoiding the conversion sleeve 92 from tilting and causing the variable-speed connecting column 93 to be stuck. The position of the conversion sleeve 92 away from the reinforcing ring 94 is fixedly connected with the sealing sleeve 91, and the position of the conversion sleeve 92 close to the reinforcing ring 94 is rotatably connected with a variable-speed connecting column 93.
