Embodiment
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
As shown in Figure 1, a kind of tension-adjusting gear of adaptive engine front end accessory gear, mainly comprises motor head accessory wheel system and belt tension control system two parts.
Motor head accessory wheel system forms primarily of crankshaft pulley 3, poly Vbelt 4, Water-pump belt wheel 2, air conditioner compressor belt pulley 5, generator belt wheel 7, power steering pump belt wheel 8, Idle wheel 9 and two idle pulleys 1.Crankshaft pulley 3 drives Water-pump belt wheel 2, air conditioner compressor belt pulley 5, generator belt wheel 7, power steering pump belt wheel 8 by poly Vbelt 4.Motor head accessory wheel system belongs to the constituent element of motor car engine, does not repeat them here.
Belt tension control system comprises piezoelectric transducer 10, angular encoder 13, comparator 14, controller 15 and final controlling element 11, piezoelectric transducer 10 is arranged on the tension force for Real-time Obtaining poly Vbelt 4 on Idle wheel 9, and angular encoder 13 is arranged in crankshaft pulley 3 for obtaining the speed of crankshaft of motor.
When the speed of crankshaft of motor is zero (before engine start and after stopping working), Idle wheel 9 is in default less belt tension position all the time, and poly Vbelt 4 maintains less tension state all the time.When the engine starts, speed of crankshaft increases gradually by zero, and controller 15 controls final controlling element 11 action at once makes Idle wheel 9 move to default larger belt tension position.After speed of crankshaft is stable, the tension value obtained by piezoelectric transducer 10 by comparator 14 is contrasted with the tension value preset, final controlling element 11 action is controlled to adjust the position of Idle wheel 9 again by controller 15, realize maintaining the stable object of belt tension, make Idle wheel 9 be in optimum position all the time, guarantee that poly Vbelt 4 is in optimum tension state all the time.
Specific works principle is as follows: utilize piezoelectric transducer 10 to obtain the impacting force that in poly Vbelt 4 operation process, Idle wheel 9 bearing is subject to, Idle wheel 9 is θ with the cornerite of poly Vbelt 4, because Idle wheel 9 does not have load, so can think Idle wheel 9 wherein side poly Vbelt 4 tension force F
1with opposite side tension force F
2equally large, the tension force F of poly Vbelt can be calculated like this by following formula.
Meanwhile, crankshaft pulley 3 is provided with angular encoder 13, for measuring speed of crankshaft and signal being passed to controller 15.First, before an engine is started, speed of crankshaft is 0, and now the belt tension value of Idle wheel 9 position is very little.When the engine starts, controller 15 makes Idle wheel 9 move to larger belt tension position by final controlling element 11 at once; When engine crankshaft steady running, now measuring poly Vbelt 4 tension force obtained will be contrasted by comparator 14 with pre-tension, when measured value and predefined value inconsistent time, controller 15 controls final controlling element 11 to adjust the position of Idle wheel 9.
As shown in Figure 2, final controlling element 11 forms primarily of oil hydraulic cylinder 6, piston rod 12,3-position 4-way electrohydraulic control 21, oil hydraulic pump 16 and fuel tank 18.Fuel tank 18 is oil hydraulic cylinder 6 fuel feeding by oil hydraulic pump 16, fuel delivery number controlled by 3-position 4-way electrohydraulic control 21.One end of piston 12 is stretched in oil hydraulic cylinder 6, and the other end of piston 12 is connected with Idle wheel 9.Controller 15 adjusts piston rod 12 by the movement controlling 3-position 4-way electrohydraulic control 21 and moves, and piston rod 12 drives Idle wheel 9 to move to suitable position again.
When measuring poly Vbelt 4 tension force that obtains and being less than predefined value, Δ F be on the occasion of, 3-position 4-way electrohydraulic control 21 left functions are connected, and the piston rod 12 on oil hydraulic cylinder 6 promotes Idle wheel 9 toward protracting, the increase of poly Vbelt 4 tension force.When measuring the poly Vbelt tension force obtained and being greater than predefined value, Δ F is negative value, 3-position 4-way electrohydraulic control 21 moves to right and right position function is connected, piston rod 12 pulls Idle wheel 9 toward retrude, and poly Vbelt 4 tension force reduces. when measuring the poly Vbelt tension force obtained and being equal with during predefined value, and Δ F=0,3-position 4-way electrohydraulic control 21 is in meta, flow is not had to export, piston rod 12 and Idle wheel 9 stop motion (locking), the state making poly Vbelt 4 put into tension force to remain constant.By the position of ACTIVE CONTROL Idle wheel 9, reach and automatically maintain the stable object of poly Vbelt 4 tension force.When after engine misses, speed of crankshaft is kept to 0, and this Time Controller 15 is by apply piston bar 12, and the position before making Idle wheel 9 retract to startup, makes the tension force of poly Vbelt 4 maintain smaller value state.
Preferably, relief valve 20 and one-way valve 19 is provided with between fuel tank 18 and 3-position 4-way electrohydraulic control 21.Relief valve 20 plays the effect of safety valve.Except this outside, oil hydraulic pump 16 is also furnished with filter 17.
As shown in Figure 3, final controlling element 11 forms primarily of linear electric motor 22 and piston rod 12.Linear electric motor 22 promote piston rod 12 and move, and piston rod 12 drives Idle wheel 9 to move to suitable position again, and controller 15 controls the clockwise and anticlockwise of linear electric motor 22.Preferably, be also provided with vibration damper 23 between linear electric motor 22 and piston rod 12, vibration damper 23, by shock absorber casing, is arranged on spring 23a in shock absorber casing and hydraulic oil 23b and forms.
Functional effect is identical with the final controlling element 11 described in Fig. 2, but it promotes piston rod 12 and Idle wheel 9 moves by controlling linear electric motor 22, and then realizes the object regulating poly Vbelt 4 tension force in real time.Because vibration damper 23 inside includes hydraulic oil 23a and spring 23b, thus can impact under each operating mode of absorption band transmission, reduce tension force fluctuation and the transverse vibration thereof of poly Vbelt 4.
Angular encoder 13 can be substituted by speed probe own in motor car engine, and controller 15 can be integrated in vehicle electronic control unit (ECU), both decreases cost like this, turn improves feasibility.
