Description
Technical field
The utility model relates to a kind of vehicle shift device, more specifically, relates to a kind of vehicle shift device that adopts the gearshift button to shift gears.
Background technology
General vehicle shift all will be trampled power-transfer clutch, makes the gear shift operation complexity, and chaufeur feels exhausted, if power-transfer clutch is not floored, also damages shifting system easily.Though without stepping on clutch, there is the shortcoming that consumption of fuel is big and speed-raising is slow during the speed-raising of stepless change vehicle.Therefore, although the stepless change vehicle comes out for a long time, but still can not replace the clutch gear-shift vehicle fully.
Summary of the invention
The purpose of this utility model will overcome the deficiencies in the prior art exactly, and a kind of light gearshift is provided.
Vehicle shift device of the present utility model, comprise pedal of clutch and clutch master cylinder, described clutch master cylinder connects with clutch booster, it is characterized in that: described clutch booster is through bilateral check valve and electromagnetic valve and pressure medium jar UNICOM, gear shift control button and controller electrically connect, when pressing described gearshift button, described controller is controlled described electromagnetic valve and is connected the pressure medium path of described pressure medium jar to described clutch booster, realizes the separation of power-transfer clutch.
By this system, not only kept the common gearshift that pin is stepped on fluid control, can shift gears according to the gearshift mode of routine; But also has the foot accelerator clutch of need not pedal, as long as just can realize the function of manual automatically controlled gearshift by next one gearshift button, promptly when chaufeur need be shifted gears, need not to depress as usual pedal of clutch, but only need when holding the shift handle gearshift, press the gearshift button.At this moment, control cock is connected, and the high-pressure medium of high-pressure medium jar is through the electromagnetic valve bilateral check valve of flowing through, and injects clutch booster through the bilateral check valve, thereby disengages the clutch, and realizes easily gearshift.After gearshift finishes, unclamp the gearshift button, the UNICOM of solenoid valve shuts high-pressure medium jar and bilateral check valve.At this moment, the high-pressure medium in the clutch booster cylinder enters by electromagnetic valve and reclaims the loop, clutch booster push rod return, and power-transfer clutch engages again, and shift process is finished.
Preferably, described pressure medium jar is an air receiver, and pressure medium wherein is an air.So just can save described recovery loop, and finish the gearshift back directly with the high pressure gas exhaust to atmosphere in the clutch booster.As an alternative be, described pressure medium jar is the high pressure oil tank, described pressure medium be oil.In this case, described pressure oil tank is led in described recovery loop.
Preferably, when shift process finishes, when unclamping described gearshift button, the air in the described clutch booster cylinder is through described electromagnetic valve exhaust to atmosphere, and power-transfer clutch engages again.
Preferably, described gearshift button is arranged on the shift handle; Described electromagnetic valve is proportion magnetic valve or high-speed electromagnetic valve; Described controller is controlled described electromagnetic valve according to sensor input signal.
In addition, on the described controller indicator lamp is housed, when described electromagnetic valve was connected, described indicator lamp was lighted.
Most preferably, described pressure medium jar is an air receiver, and pressure medium wherein is an air.
As follows according to vehicle shift device shift process of the present utility model:
When hanging 1 retaining starting in the original place, hold shift handle, press the gearshift button, gear is put to 1 retaining again, release button according to the suitable open the throttle wide of load, can be realized gentle start then.
And keep off high (low) speed retaining from low (height) speed, and press the gearshift button, gear is switched to required gear loosen button and get final product.
The principle of work of vehicle shift device of the present utility model is such:
When the original place hangs 1 retaining starting, after pressing the gearshift button, controller makes electromagnetic valve be in control position, pressure medium in the pressure medium jar is through the electromagnetic valve bilateral check valve of flowing through, inject clutch booster then, power-transfer clutch separated gradually, when the clutch booster displacement pickup detect power-transfer clutch reach separate stroke value after, controller cuts out electromagnetic valve, and pressure medium jar to the pressure medium path of clutch booster disconnects.Gear is switched to 1 retaining loosen gearshift then during button, controller receives wheel speed sensors signal, clutch booster displacement transducer signal and other parameter of system (as braking during standstill air chamber pressure, engine speed etc.), the controller control electromagnetic valve is carried out exhaust according to wheel speed signal and other parameter of system, clutch driving disc is realized slowly, steadily combination, finishes the starting of putting into gear.
When low (height) speed is kept off high (low) speed retaining, after pressing the gearshift button, controller makes electromagnetic valve be in control position, pressure medium in the pressure medium jar is through the electromagnetic valve bilateral check valve of flowing through, inject clutch booster then, power-transfer clutch separated gradually, when the clutch booster displacement pickup detect power-transfer clutch reach separate stroke after, controller cuts out electromagnetic valve, and pressure medium jar to the pressure medium path of clutch booster disconnects.Gear is switched to required gear loosen gearshift then during button, controller receives wheel speed sensors signal and other parameter of system (as braking during standstill air chamber pressure, engine speed etc.), the controller control electromagnetic valve is carried out exhaust according to wheel speed signal and other parameter of system, clutch driving disc is realized steady combination, finishes shift process.
Obviously, gearshift of the present utility model has improved the simplification and the traveling comfort of driver's operation widely, simultaneously, can avoid traditional clutch gear-shift operating mechanism owing to adopt gearshift of the present utility model, by gearshift button direct control pressure medium path, the separation that realizes power-transfer clutch with engage, so can also improve the service life of clutch gear-shift operating mechanism greatly.
