Description
Technical field
The utility model relates to a kind of automobile component, is a kind of being installed on the propons with transmission and combustion cutoff output torque function specifically, realizes the automobile component that switches between car load two-wheel drive and the four wheel drive.
Background technology
At present, the drive form of lilliput car is divided into two and drives (2WD) and 4 wheel driven (4WD), and two drive and are divided into forerunner, rear-guard, and 4 wheel driven is divided into AWD and timesharing 4 wheel driven.No matter being forerunner or rear-guard, all is to have only two wheels driving, and relatively good when travelling on steady fair running road surface, if road conditions are bad, the propulsive effort of wheel is poor, will occur skidding, dallies, situation such as sideslip.And the application of timesharing 4 wheel driven is more flexible, can switch between two-wheel drive and four wheel drive according to the ground-surface actual conditions, effectively utilizes the driving functions of car load, saves the oil consumption of car load in good time.Conversion between this two-wheel drive and the four wheel drive then needs to use between bridge power-transfer clutch to finish.
At present, generally adopt two kinds in the auto trade at home before bridge clutch: wheel limit manual clutch and wheel limit self-acting clutch, but these two kinds of power-transfer clutchs exist very big shortcoming:
(1) wheel limit manual clutch: adopt this power-transfer clutch, when the needs f-w-d, the toggle that the people need get off hub clutch is threaded to locking state (LOCK) from free state (FREE), finishes the 4 wheel driven function of automobile.When not needing f-w-d, the toggle that the people need get off hub clutch is threaded to free state (FREE) from locking state (LOCK), makes automobile recover two and drives state.This structure clutch operating inconvenience is fit to be applied on the low gear 4-wheel driven car.
(2) wheel limit self-acting clutch: when driving, need preceding hub clutch to be taken, become two and drive state with falling 1～2 meter behind the car by 4 wheel driven change two.Because its complex structure, involve great expense, poor reliability, become obsolete product at present.
Summary of the invention
The purpose of this utility model provides clutch equipment between a kind of bridge of realizing switching between car load two-wheel drive and the four wheel drive, it can make automobile change between two-wheel drive and four wheel drive, simultaneously structure advanced person, cost lower, easy to operate, be easy to promote.
The purpose of this utility model is achieved in that it comprises automobile front axle, it is characterized in that front axle is made up of inner shaft and outer semiaxis, inner shaft and outside semiaxis disconnector assembly is installed between the semiaxis, semiaxis disconnector assembly comprises a slip gear ring with the shift fork bonded assembly, the slide teeth astragal has female splines, female splines optionally is meshed with the spline of inner shaft end and the spline of outer semiaxis end, on front axle housing, be installed with air chamber, the both sides of air chamber are provided with porting, and the air chamber push rod is connected with declutch shift shaft.
By the control button in the operation operator's compartment, start valve opening solenoid and inspire vacuum reservoir valve on the motivation, relying on vacuum power to drive the air chamber push rod moves, declutch shift shaft is moved, drive coupled slip gear ring translation by shift fork, the slip gear ring is meshed with the spline of inner shaft end, the slip gear ring is meshed simultaneously with the spline of inner shaft and outer semiaxis end, thereby realize the mutual switching between two wheel drive and the four wheel drive.
The utility model has remedied the weak point of two kinds of power-transfer clutchs in the prior art fully, and navigating mate only needs just can realize switching between two wheel drive and the four wheel drive driving the automatically controlled button of in-house operation, and is easy to operate.And this apparatus structure is simple and reliable, manufacturing process is easy, and cost is low, be fit to be applied to two of various vehicles drive and 4 wheel driven between switching.
