Detailed description of the invention
The car that general engine behind front wheel, front-wheel are drive wheel to use below, trailing wheel is flower wheel, the invention will be further described by reference to the accompanying drawings:
The rotary disposable parking apparatus that completes of a kind of vehicle flower wheel of the present invention lifting is primarily of two groups of trailing wheel lifting mechanisms, the honest testing agency of wheel flutter, the near front wheel single-wheel stop mechanism, revolving power mechanism, hydraulic pressure and oil piping system, control system composition.
The rotary disposable working process completing parking apparatus of a kind of vehicle of the present invention flower wheel lifting is as follows:
Before and after parking stall, car is had to restrict, when the little needs rotation of parking space is parked: headstock tiltedly to be sailed into parking stall near the front truck tailstock; Press button of parking; Rotate steering handwheel bright to the honest indicator lamp of wheel flutter; Step on brake pedal.Micro controller system, by former car the near front wheel wheel speed sensors signal transacting, confirms that car is in dead ship condition; By confirming that wheel flutter is in honest state to Hall element 16 signal transacting; By to pressure relay 21 signal transacting, confirm that wheel is in braking mode.At this moment Single-chip Controlling two-bit triplet electromagnetic valve 38 and 2/2-way electromagnetic valve 39 are energized, and make power cylinder pressure keep wheel flutter at honest position locking; Control 2/2-way electromagnetic valve 22 to be energized, make the near front wheel single-wheel keep brake lock; Control the YA end energising of three position four-way electromagnetic valve 40, spool moves to left, hydraulic oil flows to the rodless cavity of two trailing wheel lifting mechanism telescopic hydraulic cylinders 12 through power assistance pump for steering 36, two-bit triplet electromagnetic valve 38, three position four-way electromagnetic valve 40, check valve 1, the rod chamber hydraulic oil of telescopic hydraulic cylinder 12 flows into the oil return pipe of three position four-way electromagnetic valve 40 through sequence valve 2 42, the piston rod of two telescopic hydraulic cylinders 12 stretches out, and promotes strut bar 11 and is lifted by two trailing wheels.After lifting puts in place, microprocessor detect is to lifting travel switch 9 signal, and the YA of Single-chip Controlling three position four-way electromagnetic valve 40 holds power-off, three position four-way electromagnetic valve 40 changes to meta, two trailing wheels are kept lift location by two groups of lifting mechanisms, and the lifting indicator lamp that puts in place is bright, and buzzer phone prompting lifting terminates.Chaufeur hangs D Drive, loosen the brake 17, slowly power-transfer clutch is lifted, the power of driving engine 26 is through power-transfer clutch and change-speed box 27, main reduction gear 28, diff shell 29, planetary wheel 31 passes to left half axle gear 32, right axle shaft gear 33, due to now the near front wheel single-wheel braking, the transmission shaft 34 be connected with the near front wheel and left half axle gear 32 also will remain static, at this moment planetary wheel 31 to revolve round the sun and around compensating-gear shaft 30 rotation around left half axle gear 32, planetary wheel 31 rotation drives right axle shaft gear 33, right transmission shaft 35, off front wheel 2 rotates forward, off front wheel 2 creates the power rotated around the near front wheel 1, two trailing wheel lifting mechanism cardan wheels 4 are according to the effect of rotary power, automatically the angle rotated around the near front wheel 1 is adjusted, thus make whole vehicle body start to rotate around the near front wheel 1, when vehicle body revolves timing, step on brake pedal 17, stop positive vehicle.Reset is parked button, the YB end energising of Single-chip Controlling three position four-way electromagnetic valve 40, spool moves to right, hydraulic oil is through power assistance pump for steering 36, two-bit triplet electromagnetic valve 38, three position four-way electromagnetic valve 40, check valve 2 44 flows to the rod chamber of two trailing wheel lifting mechanism telescopic hydraulic cylinders 12, the rodless cavity hydraulic oil of telescopic hydraulic cylinder 12 flow to the oil return pipe of three position four-way electromagnetic valve 40 through sequence valve 1, the piston rod of two telescopic hydraulic cylinders 12 shrinks, put down two trailing wheels, strut bar 11 return, when microprocessor detect is to retraction stroke switch 10 signal, to all electromagnetic valve power-off, vehicle recovers original state of a control, complete overall process of parking.
When needs sail out of parking stall, hang reverse gear by aforesaid operations program.The steps include: that (1) presses button of parking; (2) rotate steering handwheel and step on brake pedal to the honest indicator lamp of wheel flutter bright (3); (4) lifting put in place indicator lamp time, hang reverse gear, the tailstock rotates position; (5) reset and to park button, shrink the indicator lamp that puts in place bright time, vehicle recovers original state of a control, completes and sails out of overall process.
When the disposable tune operation of needs, hang D Drive by aforesaid operations program, rotation body 180 degree.The steps include: that (1) is from roadside one vehicle commander's distance stagnation of movement; (2) button of parking is pressed; (3) rotate steering handwheel and step on brake pedal to the honest indicator lamp of wheel flutter bright (4); (5) lifting put in place indicator lamp time, hang D Drive, the tailstock revolves turnback, steps on stopping-down; (6) reset and to park button, shrink the indicator lamp that puts in place bright time, vehicle recovers original state of a control, completes disposable tune overall process.
