Abstract
The utility model relates to a clutch separation indicating and abrasion alarm system, which comprises an inductance sensor arranged on a clutch booster, an inductance detecting module and a controller connected with the inductance detecting module; the inductance detecting module is also provided with a reset switch; the controller compares the variable inductance from the inductance sensor with a set value; when the separation of the clutch is judged to be in the best value according to the detected signal, an instruction is sent, so that the indicating device sends an instruction to shift; when the abrasion of the clutch reaches the preset abrasion limit value according to the detected signal, another instruction is sent, so that the alarm device gives alarm. After adoption of the clutch separation indicating and abrasion alarm system of the utility model, drivers can shift under the best separation status of the clutch, so as to greatly reduce injury to vehicle parts. When abrasion of the clutch is going to affect the conditions of the vehicle, alarm is given in time, so as to prevent unnecessary energy loss and the embarrassed phenomenon of failure to realize transmission.
Description
Technical field
The utility model relates to clutch separation indication and wearing and tearing warning device.
Background technique
Clutch is an important transmission part on the automobile, and its two friction plate separates during gear shift, engages with transferring power again after gear shift finishes.For driving technology is not very consummate driver, grasps bad gear shift opportunity often, and with regard to gear shift, the result makes parts cause damage under the situation that clutch does not separate fully.And, because clutch is by two friction plate transmissions, so can occur the wearing and tearing of friction plate inevitably.When the degree of wear is big, can cause joint malfunctioning, normally transmission of vehicle.Even without may wear to obvious joint when malfunctioning, also may cause transfer motion power not enough, the phenomenon that throws switch because can not normal engagement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of clutch separation indication and wearing and tearing warning device are provided.
Clutch separation indication of the present utility model comprises clutch booster with the wearing and tearing warning device, on clutch booster, dispose inductive pickup, the push rod of this inductive pickup and the push rod of clutch booster are synchronized with the movement, one inductance value testing module connects with this inductive pickup, reception is from the inductance value variable signal of inductive pickup, and it is passed to a controller that connects with it, also have reset switch on the described inductance value testing module, in described controller, parameter according to vehicle and clutch operating mechanism configures optimal separation positional value and wear limit positional value in advance, this controller connects an indicating device and a warning device, the controller inductance value variable quantity and the described setting value of self-inductance sensor in the future compares, when the separation of judging clutch according to detected signal reaches the optimal separation value, send an instruction, make described indicating device send the indication that to shift gears, when the wearing and tearing of judging clutch according to detected signal reach the preset wear limiting value, send instruction, warning device is reported to the police.
After the clutch booster entrucking that has inductive pickup is debugged, press the reset switch of inductance value testing module, this moment, system can note the inductance value of clutch booster entrucking position.When let slip the clutch, drive the clutch booster push rod by clutch master cylinder and travel forward, make clutch separation.In this process, because driving the sensor push rod, the clutch booster push rod travels forward synchronously, cause the variation of sensor electrical sensibility reciprocal, the variation of inductance value is directly proportional with the stroke of push rod.The inductance value testing module passes to controller to detected inductance value delta data.Controller compares itself and the optimal separation positional value that pre-deposits.Send indication when reaching clutch optimal separation positional value, the prompting driver can carry out gear shift.On the other hand, controller is connected the two-position three way magnetic valve that connects the gear shift servo-cylinder automatically, thereby avoids some to diminish the operation of clutch or miscellaneous part.
Along with the wearing and tearing of clutch friction plate, under the clutch spring effect, the booster push rod drives the sensor push rod and moves backward when operated clutch not, cause the variation of clutch state lower sensor inductance value.The inductance value testing module passes to controller to detecting inductance value delta data.Controller compares the wear limit rating of these data and setting, sends warning when controller finds that the inductance value variation reaches the clutch abrasion limit position.
After new clutch friction plate is changed debugging, press the reset switch of inductance value testing module once more, system recovers proper functioning again.
Preferably, described controller is ECU.
Preferably, described indicating device is a tutorial light, but also can be the indicating device of other form, for example indicating device of speech form.
Preferably, described warning device is a phonetic alarm, but also can be other forms of warning device, for example blinking light alarm.
Preferably, the indication of described clutch separation also connects a solenoid valve with the controller (ECU) of the warning device that weares and teares, a two-position three way magnetic valve for example, and it controls a power assisted gearshift cylinder.
After adopting clutch separation indication of the present utility model and wearing and tearing warning device, the driver can shift gears under the optimal separation state of clutch, thereby has reduced the infringement to vehicle component widely.When clutch abrasion when being about to influence vehicle condition, in time report to the police, avoided unnecessary energy loss, even can't realize the awkward situation of transmission.

Embodiment
Below in conjunction with accompanying drawing a most preferred embodiment of the present utility model is described, so that more be expressly understood the utility model.
As shown in Figure 1, the clutch separation indication of most preferred embodiment of the present utility model and wearing and tearing warning device comprise the clutch booster 4 of a charged propagated sensation sensor, inductive pickup push rod in it is synchronized with the movement with clutch push rod under the drive of clutch push rod, cause the variation of inductance value, the variation of this inductance value is directly proportional with the stroke of push rod.One inductance value testing module 5 connects with inductive pickup, detected inductance value is changed passing to an ECU.Optimal separation positional value and wear limit positional value have been set according to the parameter of different vehicles and clutch operating mechanism in advance in this ECU.ECU with detected inductance value change with its in the optimal separation positional value that stores make comparisons, when reaching clutch optimal separation position, send instruction, this moment, tutorial light 7 was lighted, the prompting driver can gear shift.And when tutorial light 7 does not work, illustrate that clutch is not in the optimal separation state, be not suitable for gear shift.At this moment, ECU can also connect the two position three-way valve 10 that connects the gear shift servo-cylinder automatically, thereby has avoided some to impair the operation of clutch or other parts.
When wearing and tearing appearred in clutch friction plate, under the clutch spring effect, the booster push rod drove the sensor push rod and moves backward, causes the variation of sensor electrical sensibility reciprocal, and inductance value testing module 5 is passed to ECU to detected inductance value delta data.ECU compares itself and preset wear limit position value, and when the wearing and tearing of clutch reached capacity the position, ECU sent instruction, changes clutch friction plate by the phonetic alarm device prompting.New clutch friction plate is pressed inductance value testing module reset switch, the system recovery proper functioning after changing and debugging once more.
