Description
Technical Field
[0001] The invention belongs to the technical field of gearboxes, and in particular relates to an integrated manual gearbox control assembly. Background Art
[0002] Technological development has driven the development of the automobile industry. In recent years, automobile transmission manufacturers have developed high-end transmissions such as AMT and AT through continuous efforts and innovation, making transmission operation simpler and more comfortable. However, due to high costs, low transmission efficiency, high fuel consumption and other issues, they still have not achieved good market performance.
[0003] At present, manual mechanical transmissions are still the mainstream of domestic automobile configurations due to their simple structure, high reliability, low price, low maintenance costs and many other advantages. With the deepening of the people-oriented design concept and the younger drivers, the driving comfort requirements for manual transmissions of the whole vehicle are getting higher and higher. Although the transmission with synchronizer solves the problems of impact and gear knocking during the shifting process, the shifting comfort is affected by the limitations of the transmission structure, the large shifting force, especially the large shifting force when downshifting, and the problem of the synchronizer secondary shift ring.
[0004] Adding a shift booster can not only reduce the shift force, but also weaken the secondary shift impact of the synchronizer, greatly improving the shift comfort. Matching a shift booster becomes the only choice for improving the shift comfort of a manual transmission with synchronizer.
[0005] The control window of the existing transmission control assembly is generally arranged in the middle of the control assembly, and the shift booster is arranged at one end of the transmission control assembly. At this time, when the transmission control is matched with the shift booster, the shift booster is far away from the shift dial, which affects the overall rigidity of the control assembly and the consistency of the transmission shift performance. At the same time, since the shift force is light after adding the shift booster, some drivers may shift without stepping on the clutch, which will cause damage to the synchronizer and cause the vehicle to be out of service. This will not only cause economic losses to users and cause user dissatisfaction, but also increase maintenance service costs, affecting the company's brand image and market influence. Summary of the invention

[0013] Furthermore, in order to ensure the consistency of the gear shift stroke, a gear limit pin is set on the side of the operating shell corresponding to the gear shift booster.

[0014] Furthermore, the interlocking groove is a V-shaped groove, and the end of the interlocking rod is a conical surface that matches the interlocking groove.

DETAILED DESCRIPTION
[0026] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] like Figure 1 As shown, an integrated manual transmission control assembly in this embodiment includes an inner shaft 1, an outer shaft 2, a control housing 4, a shift assembly, a gear selection assembly and a shift booster 11.
[0028] The inner shaft 1 is arranged through the operating shell 4, and the outer shaft 2 is sleeved between the inner shaft 1 and the operating shell 4; an operating window 19 is provided on the operating shell 4, and the shift booster 11 is arranged at one end of the operating shell 4 and is connected to the inner shaft 1 and the outer shaft 2, and the operating window 19 is arranged near the shift booster 11, and an interlocking groove 101 is provided at a position of the inner shaft 1 away from the shift booster 11, and a reverse gear lock groove 102 is provided on the inner shaft 1. In this embodiment, the interlocking groove 101 is a V-shaped groove, and other shapes can also be set in other embodiments to ensure that the interlocking rod 71 locks the inner shaft 1; a neutral indication groove 104 is provided on the other side of the inner shaft 1 opposite to the interlocking groove 101, and a reverse gear indication groove 103 is provided on the other side of the inner shaft 1 opposite to the reverse gear lock groove 102.
[0029] A locking mechanism for locking the gear position when the clutch is not engaged is provided at a position corresponding to the interlocking groove 101 on the operating housing 4, and a reverse gear lock pin 5 and a reverse gear lock spring 9 are provided at a position corresponding to the reverse gear lock groove 102 of the operating housing 4. The reverse gear lock pin 5 is pushed into the reverse gear lock groove 102 under the action of the reverse gear lock spring 9, and a reverse gear indication switch mounting hole B is provided on the other side of the operating housing 4 opposite to the position where the reverse gear lock pin 5 is installed, and a reverse gear indicator light switch is installed in the reverse gear indication switch mounting hole B, and the contact of the reverse gear indicator light switch is located in the reverse gear indication groove 103, and a neutral gear indication switch mounting hole C is provided on the other side of the operating housing 4 opposite to the locking mechanism, and a neutral gear indication switch is installed in the neutral gear indication switch mounting hole C, and the contact of the neutral gear indication switch is located in the neutral gear indication groove 104.
[0030] like Figure 3 As shown, the locking mechanism includes a piston chamber 42, an interlocking piston 7, a locking spring 8 and a cylinder cover 41; the piston chamber 42 is arranged on the operating housing 4, the interlocking piston 7 is installed in the piston chamber 42, a cavity 43 is formed between the interlocking piston 7 and the piston chamber 42, and an interlocking rod 71 is arranged on the interlocking piston 7, and the interlocking rod 71 passes through the operating housing 4 and is pushed into the interlocking groove 101 of the inner shaft 1. In the embodiment, the end of the interlocking rod 71 is a cone that matches the interlocking groove 101; the side wall of the operating housing 4 is provided with a cavity 43 The interlocking cylinder air hole A is connected, and the interlocking cylinder air hole A is connected to the clutch sub-pump and the auxiliary box interlocking valve; the cylinder head 41 is installed at the position of the piston chamber 42 corresponding to the operating housing 4; the locking spring 8 is installed between the interlocking piston 7 and the cylinder head 41 and has a certain pre-compression amount; the interlocking piston 7 is provided with a through axial hole 72, and the axial hole 72 is connected to the space where the locking spring 8 is installed at the rear end of the interlocking piston 7. When the locking spring 8 is further compressed, the gas pressure in the installation space of the locking spring 8 can be released, so that the unlocking is rapid.
[0031] like Figure 4 As shown, a gear-engagement limit pin 17 is provided on the side of the operating housing 4 corresponding to the shift booster 11. In this embodiment, an air circuit control valve 10 is also provided at the operating window 19. When the gearbox is in neutral, the air circuit control valve 10 supplies air to the auxiliary box to realize high and low gear switching of the auxiliary box.
[0032] The shift assembly includes a shift head 3, a groove is provided on the upper part of the shift head 3, the shift head 3 is connected to the inner shaft 1 and the outer shaft 2 at the same time through a cylindrical pin, a gap is left between the cylindrical pin and the inner shaft 1, and the inner shaft 1 is connected to the internal shaft of the shift booster 11 through the inner shaft shift block 16; an arc groove is provided on the shift head 3, and an integrated self-locking pin 14 is added to the side of the shift head 3, and the integrated self-locking pin 14 cooperates with the arc groove; when the driver performs the shift action, the inner shaft 1 is first rotated to drive the booster inner shaft shift block 16 to rotate, because there is a gap between the inner shaft 1 and the cylindrical pin, the shift head 3 does not move at this time, and the inner shaft shift block 16 shifts the internal shaft of the booster to open the valve core of the shift booster 11, and if the booster has air intake at this time, the compressed air enters the booster cylinder to produce a boosting effect, which drives the outer shaft 2 to rotate, and drives the shift head 3 to rotate to complete the gear shifting action.
[0033] like Figure 2 As shown, the gear selection assembly includes a gear selection shaft 12, a gear selection dial head 13 and a gear selection balance spring 6. The gear selection shaft 12 is fixedly connected to the gear selection dial head 13. The gear selection dial head 13 extends into the groove on the upper part of the gear shift dial head 3. The gear selection balance spring 6 is sleeved on the other end of the inner shaft 1. When the transmission is not in gear, the gear shift dial head 3 is kept in the neutral position under the action of the gear selection balance spring 6. When the gear selection dial head 13 rotates, the gear shift dial head 3 drives the inner shaft 1 to move axially along the outer shaft 2 to select gear.
[0034] The working process of the present invention is as follows:
[0035] When the car needs to shift gears, first step on the clutch to shift the transmission to neutral, then rotate the shift shaft 12 and the shift selector 13 to drive the shift selector 3 to move axially to the position where the gear needs to be engaged. At this time, because the transmission is in the neutral position in the gear engaging direction, the neutral indicator switch contact is in the neutral indication groove 104 of the inner shaft 1, and the neutral indication is turned on. At this time, if the auxiliary box is in high gear or low gear, the interlock cylinder is ventilated, and the compressed gas pushes the interlock piston 7 out of the inner shaft 1, and the inner shaft 1 can be easily rotated to open the The booster cylinder of the shift booster 11, the output force of the booster cylinder acts on the outer shaft 2 to drive the outer shaft 2 to rotate and drive the shift dial 3 to rotate to complete the gear shifting. The outer shaft 2 rotates and the neutral gear indicator switch is pushed out of the neutral gear indicator groove 104, and the switch is disconnected; if the selected position is reverse gear, when rotating in the gear shifting direction, the reverse gear indicator groove 103 on the inner shaft 1 that cooperates with the reverse gear indicator switch contact rotates, pushing the reverse gear indicator switch contact, and the reverse gear indicator light is turned on, reminding the driver to prevent misoperation when shifting reverse gear. If the gear selected by the driver is high-low gear switching, since the auxiliary box interlock valve is closed during the high-low gear switching of the auxiliary box, the shift booster 11 and the piston chamber 42 are not ventilated at this time, and the shift booster 11 has no boosting effect. The interlock piston 7, under the action of the lock spring 8 in the pre-compressed state, pushes the lock rod 71 on the interlock piston 7 into the interlock groove 101 on the inner shaft 1, preventing the inner shaft 1 from rotating, and the main box cannot be engaged, thereby protecting the auxiliary box synchronizer. Similarly, if the driver does not step on the clutch, there is no gas input to the auxiliary box interlock valve. At this time, even if the auxiliary box is in the high or low gear position, the shift booster 11 and the piston chamber 42 are not ventilated. The rotation of the inner shaft 1 needs to overcome the spring force of the lock spring 8 in the piston chamber 42, and the shift booster 11 has no assisting effect. It is also very difficult to shift the main box synchronizer, forcing the driver to step on the clutch to shift gears, thereby achieving the purpose of protecting the main box synchronizer.
[0036] Neutral indication: Port C is the installation hole for the neutral indication switch. When the transmission is in neutral position, the contact of the neutral indication switch is in the neutral indication groove 104 on the inner shaft 1, and the circuit is connected. When the transmission is in gear, the inner shaft 1 rotates, the neutral indicator light switch is compressed, and the circuit is disconnected.
[0037] Reverse gear indication and reverse gear lock: When the car wants to shift into reverse gear, the shift knob 3 must first be moved to the right to select the reverse gear position. During the movement of the shift knob 3 to the right, on the one hand, the gear selection balance spring 6 must be compressed, and on the other hand, the reverse gear lock pin 5 is lifted up by the inner shaft 1 to compress the reverse gear lock spring 9, causing the gear selection force to suddenly increase, reminding the driver that the selected gear is the reverse gear, which is the reverse gear lock. Port B on the other side opposite to the reverse gear lock is the reverse gear indication switch mounting hole. When the reverse gear is selected and rotated in the gear shifting direction, the reverse gear indication groove 103 on the inner shaft 1 that cooperates with the reverse gear indicator light switch contact rotates, pushing the reverse gear indicator light switch contact, and the reverse gear indicator light is turned on, reminding the driver again that the gear position is the reverse gear to prevent safety accidents caused by misoperation.
[0038] Main box synchronizer protection function: The other end of the operating device housing 4 is provided with an interlocking cylinder, in which an interlocking piston 7 and a locking spring 8 are installed. Figure 3 As shown, one end of the interlocking piston 7 is an interlocking rod 71 with a tapered surface. Under the action of the lock spring 8, the tapered surface on the interlocking rod 71 cooperates with the V-shaped interlocking groove 101 on the inner shaft 1 to prevent the inner shaft 1 from rotating or requiring a lot of force to rotate. The air inlet A is the air inlet of the interlocking cylinder, which is linked to the clutch slave pump. Only when the clutch is pressed can the compressed air enter the interlocking cylinder from the air reservoir through the clutch slave pump, pushing the interlocking piston 7 to leave the inner shaft 1 and unlock, thereby easily shifting gears, eliminating the irregular operation of shifting gears without stepping on the clutch, and protecting the main box synchronizer.
[0039] Auxiliary box synchronizer protection function: When the transmission is a main-auxiliary box structure, the air intake of the interlock cylinder must also pass through the auxiliary box interlock valve. When the clutch is pressed, the compressed air is pumped to the auxiliary box interlock valve through the clutch sub-pump. At this time, if the auxiliary box synchronizer is in high gear or low gear, the air circuit in the auxiliary box interlock valve is connected, and the compressed air can enter the shift booster 11 and the lock cylinder 7. The lock is released, and the main box can easily shift gears; if the auxiliary box synchronizer is switching between high and low gears, the auxiliary box interlock valve air circuit is disconnected, and the compressed air cannot enter the shift booster 11 and the lock cylinder 7. The inner shaft 1 is locked, and the main box cannot shift gears. The gear can be shifted only after the auxiliary box synchronizer is switched.
[0040] Gear shifting limit function: In order to ensure the consistency of the gear shifting stroke, a gear shifting limit pin 17 is added to the side of the booster inner shaft shift block 16. The gear shifting limit pin 17 is fixed to the side of the operating housing 4 by a screw plug 18. When the booster inner shaft shift block 16 rotates to the designed gear shifting angle, the gear shifting limit pin 17 contacts the side of the booster inner shaft shift block 16 to prevent the booster inner shaft shift block 16 from continuing to rotate.
[0041] The present invention also integrates the following functions: the side surface of the shift head 3 is designed with three arc grooves matching the steel ball of the integrated self-locking pin 14, corresponding to the three positions of the transmission gear shifting direction, which can realize the positioning of the neutral gear and the gear shifting position, that is, the gear self-locking function; the shift head 3 is equipped with a gear interlocking block 15, and the shift head 3 can only be rotated to engage the gear at the gear selection position aligned with the gear interlocking block 15, and the other positions cannot be moved due to the restriction of the interlocking block, thereby realizing the gear interlocking function.
