In view of the above, the present invention provides a vehicle including a sub-transmission connected to a main transmission, the sub-transmission including a vehicle sub-transmission shifting device, fig. 1 is an embodiment of the vehicle sub-transmission shifting device according to the present invention, and since the main inventive point of the present invention lies in the improvement of the vehicle sub-transmission shifting device 100, the following description mainly refers to the vehicle sub-transmission shifting device 100 with reference to the specific drawings.
Referring to fig. 1, the vehicle range-changing sub-transmission shifting device 100 according to the present invention includes a housing (not shown in the drawings), a moving member 1, a shift fork 2, a control circuit 4, and an elastic restoring member 5, wherein the housing has a plurality of gears (not shown in the drawings) sequentially arranged along a first direction, and the plurality of gears include a safety gear; the moving member 1 is movably mounted to the housing in the first direction; the gear shifting fork 2 is arranged on the moving part 1; the driver 3 is arranged on the shell and can be connected with the moving piece 1 in a clutching way; the control circuit 4 is electrically connected with the driver 3, so that when the driver 3 is controlled to be connected with the moving member 1, the shifting fork 2 is driven to switch among the plurality of gears by adjusting the moving amount of the moving member 1 in the first direction; the elastic reset piece 5 is arranged between the shell and one end part of the moving piece 1 and used for driving the shifting fork 2 to reset to the safe gear by pushing the moving piece 1 to move when the control circuit 4 controls the driver 3 and the moving piece 1 to be disconnected.
In the technical scheme provided by the invention, when the driver 3 is in a normal working state and is connected with the moving member 1, the control circuit 4 can adjust the moving amount of the moving member 1, so that the shifting fork 2 is accurately moved to a required gear position through the moving member 1; when 3 operating condition of driver is unusual and with during moving member 1 disconnection, elasticity piece 5 accessible elasticity restoring force promotes moving member 1 removes, drives shift fork 2 removes to safe gear department, ensures to drive safety, has the advantage that the structure is simplified and convenient operation.
It is understood that the housing can be directly the casing of the sub-gearbox, in which the mobile element 1, the shift fork 2, the actuator 3 and the elastic return element 5 are mounted; of course, the housing may be a structure independent of the sub-transmission, and may be fixedly mounted in the sub-transmission by screwing, bonding, fastening, or adsorbing. The plurality of gears and the gears of the sub-transmission case are arranged in a one-to-one correspondence manner, for example, the sub-transmission case shifts gears by moving a sliding gear to engage with different transmission gears, and the plurality of gears are arranged in a one-to-one correspondence manner with a plurality of engagement positions of the sliding gear, and at this time, the first direction is the axial direction of the sliding gear. The safe gear may be any one of the plurality of gears, for example, may be the first, any intermediate, or the last one of the plurality of gears in the first direction. When the shift fork 2 is moved to the safe gear, the vehicle is in a safe state or a normal state.
The moving member 1 is movable relative to the housing, and the shift fork 2 is disposed at any position on the moving member 1, for example, at an end portion or a middle portion of the moving member 1. The gear shifting fork 2 is provided with a mounting end and a shifting fork end which are oppositely arranged, the mounting end of the gear shifting fork 2 is fixedly mounted on the moving member 1, and the shifting fork end faces towards the side where the gears are located and extends to move to different gears under the driving of the moving member 1, so that the sliding gears are shifted to different meshing positions.
The driver 3 is detachably connected to the moving member 1, for example, the vehicle sub-transmission gear shifting device 100 is provided with an electromagnetic clutch, the electromagnetic clutch is electrically connected to the control circuit 4, the electromagnetic clutch is arranged between the driver 3 and the moving member 1, and can realize connection between the driver 3 and the moving member 1 when power is on and separation between the driver 3 and the moving member 1 when power is off. The technology of the control circuit 4 for implementing the above functions is well-established, and the control circuit 4 is, for example, a switch circuit, which correlates different electrical signals with the movement amount, or an integrated control chip, which is not described in detail herein.
Specifically, when the vehicle sub-transmission gear shifting device 100 is in a normal working state, the control circuit 4 controls the driver 3 to be connected with the moving member 1, the driver 3 provides driving force for the moving member 1 to move, and the moving amount of the moving member 1 is controlled by the control circuit 4, so that the moving member 1 can drive the shifting fork 2 to accurately move to different gears, and the shifting is automatically and conveniently performed. On the contrary, when the vehicle sub-transmission gear shifting device 100 is in an abnormal working state, the control circuit 4 controls the driver 3 to be disconnected from the moving member 1, and the elastic resetting member 5 applies elastic restoring force to the moving member 1, so that when the elastic resetting member 5 is restored to an initial state, the gear shifting fork 2 is just driven to the safe gear position.
Further, in the present embodiment, the moving member 1 is a worm 11; the vehicle range-box shifting device 100 further comprises a worm wheel 6 engaged with the worm 11; the drive 3 is connected to the worm wheel 6 in a clutchable manner. The driver 3 is, for example, a brushless motor having a rotation output shaft, the rotation output shaft of the brushless motor is connected to the worm wheel 6, and the worm wheel 6 is engaged with the worm 11 to convert the rotation of the worm wheel 6 into the movement of the worm 11, that is, the moving member 1. The arrangement of the worm wheel 6 and the worm 11 helps to increase the size of the vehicle range-changing device 100 in space, so that the overall structure of the vehicle range-changing device 100 is more compact; the engagement between the worm wheel 6 and the worm 11 has self-locking property, so that when the worm wheel 6 is engaged with the worm 11, the elastic restoring force applied to the worm 11 by the elastic restoring piece 5 cannot drive the worm 11 to move reversely.
In this embodiment, the vehicle range-changing device 100 includes a push button 9, and the push button 9 is electrically connected to the control circuit 4 for triggering a push signal, so that the control circuit 4 controls the actuator 3 to operate according to the push signal. The pressing signal triggered by the pressing of the key 9 is related to the level signal sent by the pressing of the key 9; the number of the pressing keys 9 can be one or more, and a plurality of the pressing keys 9 can correspondingly control different working states of the driver 3, such as opening, closing, steering, speed regulation and the like; the pressing key 9 can also control the driver 3 to work by controlling the electromagnetic clutch. Taking the example that the pressing key 9 controls the electromagnetic clutch to disconnect and connect the driver 3 and the worm wheel 6, the pressing signal triggered by the pressing key 9 includes a high level signal and a low level signal, wherein the high level signal can be related to the electromagnetic clutch to connect the driver 3 and the worm wheel 6; the low level signal can be associated with the electromagnetic clutch to disconnect the driver 3 from the worm wheel 6. Due to the arrangement of the press key 9, the gear shifting control of the vehicle auxiliary gearbox gear shifting device 100 is more convenient, and the user experience is improved.
In addition, the vehicle range-changing device 100 further includes an indicator light electrically connected to the control circuit, and the indicator light changes color to indicate the state of the vehicle range-changing device 100.
In view of the above, the vehicle range-changing device 100 has different shifting modes when in different operating states, and there are various technical solutions for determining that the vehicle range-changing device 100 is in different operating states, two of which will be listed below.
In this embodiment, the vehicle range-changing device 100 further includes a position sensor 7, and the position sensor 7 is electrically connected to the control circuit 4 for detecting a rotational displacement amount of the rotary output shaft. When the driver 3 is a brushless motor, the position sensor 7 is, for example, a hall position sensor. Specifically, in one embodiment, the control circuit 4 performs a self-test after the vehicle range-changing device 100 is powered on, and the indicator light at the key 9 is turned off when the self-test result is normal. When a switch for representing gear shifting in the press key 9 is pressed, the vehicle auxiliary transmission gear shifting device 100 self-checks the rotation displacement measured by the position sensor 7 in real time according to a preset period, namely the actual rotation displacement corresponding to the rotation output shaft of the driver 3, and when the driver 3 works normally, the indicator light turns green, which indicates that the gear shifting can be normally controlled according to the requirements of a driver; when the deviation between the rotation displacement measured by the position sensor 7 and the actual rotation displacement of the rotation output shaft of the driver 3 exceeds the preset threshold value in the program of the control circuit 4 after the vehicle auxiliary transmission gear shifting device 100 is self-checked or in real-time operation, or the state of the driver 3 does not accord with the control quantity in the program of the control circuit 4, that is, the driver 3 works abnormally, the driving function of the driver 3 needs to be closed, meanwhile, the control circuit 4 outputs a fault code and controls the indicator light on the pressing key 9 to turn red, and the system enters a protection mode and returns to a safe gear.
In addition, in this embodiment, the vehicle range-changing device 100 further includes a displacement sensor 8, wherein the displacement sensor 8 is electrically connected to the control circuit 4 for detecting a linear displacement of the moving member 1, so that the control circuit 4 can determine an operating state of the driver 3 according to the rotational displacement and the linear displacement. Since the geometric parameters of the worm wheel 6 and the worm 11 are known, the theoretical correspondence between the rotational displacement and the linear displacement can be calculated. When the control circuit 4 determines that the actual correspondence relationship between the rotational displacement and the linear displacement conforms to the theoretical correspondence relationship, it determines that the brushless motor, the worm wheel 6 and the worm 11 are in a normal working state, and at this time, the linear displacement is the movement amount of the shift fork 2; on the contrary, when the control circuit 4 determines that the actual corresponding relationship between the rotational displacement and the linear displacement does not conform to the theoretical corresponding relationship, it is determined that at least one of the brushless motor, the worm wheel 6 and the worm 11 is in an abnormal state, at this time, the deviation between the linear displacement and the movement amount of the shift fork 2 is large, the connection between the brushless motor and the worm wheel 6 needs to be disconnected, the elastic reset piece 5 moves the shift fork 2 to the safety gear, and the control circuit 4 stores a fault code to light an indicator light on the pressing key 9 to be red, so that the maintenance is facilitated.
In this embodiment, the elastic reset member 5 is a spring member, and the spring member is sleeved on one end of the moving member 1; the side wall of the end part of the moving piece 1 connected with the spring part is convexly provided with an annular step 111, and the annular step 111 and the shell at the corresponding position limit the spring part together. The spring part is directly sleeved on the moving part 1 and is limited between the annular step 111 and the inner wall of the shell. The spring member is in a compression deformation state when the shift fork 2 is not moved to the safety gear, applies an elastic restoring force to the moving member 1, but the moving member 1 is restricted by the driver 3 connected thereto and does not move reversely; when the moving member 1 is disconnected with the driver 3, the driver 3 eliminates the limitation of the moving member 1, so that the moving member 1 drives the shifting fork 2 to move towards the safe gear under the pushing of the elastic restoring force of the spring part, and the spring part is in a release state just when the shifting fork 2 moves to the safe gear.
It should be noted that the vehicle further includes an on-board terminal, namely an ECU (electronic control Unit), which may directly constitute the control circuit 4, and is beneficial to the integration of the vehicle rangebox shift apparatus 100; or the control circuit 4 is electrically connected with the vehicle-mounted terminal to form one of the components of the vehicle-mounted terminal.
In addition, the invention also provides a control method of the vehicle auxiliary gearbox gear shifting device, and fig. 2 to 3 show a specific embodiment of the control method of the vehicle auxiliary gearbox gear shifting device provided by the invention.
Referring to fig. 2, in the first embodiment of the method for controlling the gearshift 100 of the vehicle range-shifting unit according to the present invention, the method includes the following steps:
step S10: controlling the driver 3 to drive the worm 11 to move through the worm wheel 6;
in this embodiment, the control circuit 4 controls the electromagnetic clutch to connect the driver 3 and the worm wheel 6, and controls the driver 3 to be turned on, and the worm wheel 6 drives the worm 11 to move, so as to control the position sensor 7 and the displacement sensor 8 to work.
Step S20: obtaining the rotational displacement measured by the position sensor 7 and the linear displacement measured by the displacement sensor 8;
in the present embodiment, the amount of rotational displacement and the amount of linear displacement can be obtained by reading the measurement value of the position sensor 7 and the measurement value of the displacement sensor 8. The measured values of the position sensor 7 and the displacement sensor 8 are directly sent to the control circuit 4 for data processing. It should be noted that the control circuit 4 may preset the acquisition cycle of the rotational displacement amount and the linear displacement amount, and the control circuit 4 needs to ensure that the obtained rotational displacement amount and the obtained linear displacement amount are consistent at the acquisition time point or the acquisition time period.
Step S30: judging whether the corresponding relation between the rotation displacement and the linear displacement meets a preset condition or not;
step S31: and when the corresponding relation between the rotation displacement and the linear displacement meets a preset condition, the worm 11 is controlled to move to a required gear through the driver 3.
In this embodiment, according to the geometric parameters of the worm wheel 6 and the worm 11, a theoretical correspondence between the rotational displacement and the linear displacement may be calculated, and when the actual correspondence between the rotational displacement and the linear displacement conforms to the theoretical correspondence, for example, when the deviation between the rotational displacement and the linear displacement is within a reasonable range, the driver 3, the worm wheel 6, and the worm 11 are all in a normal state before representing, and the control circuit 4 may control the worm 11 to move to a required gear through the driver 3.
Next, referring to fig. 3, in the second embodiment of the method for controlling a subtransmission gear shifting apparatus 100 according to the invention, after step S30, the method further includes:
step S32: when the corresponding relation between the rotary displacement and the linear displacement does not meet the preset condition, the driver 3 and the moving part 1 are controlled to be disconnected, so that the elastic reset part 5 drives the gear shifting fork 2 to move to the safe gear.
In this embodiment, when the actual corresponding relationship between the rotational displacement and the linear displacement does not conform to the theoretical corresponding relationship, for example, the deviation between the rotational displacement and the linear displacement exceeds a reasonable range, it indicates that at least one of the driver 3, the worm wheel 6 and the worm 11 is in an abnormal state, the control circuit 4 does not control the driver 3, and the elastic reset member 5 pushes the shift fork 2 to move to the safe gear, so as to ensure the safety of the vehicle.
In one embodiment, the hall position sensor, the displacement sensor 8, the brushless motor, the electromagnetic clutch, the push key 9 and the indicator light are all electrically connected to the ECU. When a driver presses the pressing key 9, the ECU firstly controls the electromagnetic clutch to connect the brushless motor and the worm wheel 6, so that the brushless motor can drive the worm 11 to move through the worm wheel 6, and then the gear shifting fork 2 is driven to move. Then, if the rotation displacement and the linear displacement respectively measured by the hall position sensor and the displacement sensor 7 received by the ECU correspond to the corresponding relationship, it is indicated that the brushless motor is working normally at present, the indicator light is green, and the shift fork 2 can be driven by the brushless motor to realize phase switching among a plurality of gears; on the contrary, if ECU received hall position sensor reaches when displacement sensor 7 respectively measured rotary displacement and linear displacement volume do not accord with the corresponding relation, it explains now brushless motor work is unusual, the pilot lamp is red, ECU control electromagnetic clutch disconnection brushless motor reaches worm wheel 6, worm 11 is in under the promotion of elasticity reset 5, drive shift fork 2 of shifting moves to safe gear. Of course, press once more when the driver when pressing key 9, ECU controls equally electromagnetic clutch disconnection brushless motor reaches worm wheel 6, worm 11 is in under the promotion of elasticity piece 5 that resets, drive shift fork 2 removes to safe gear, can't pass through brushless motor realizes shift fork 2's gear shifting.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
