Abstract
The utility model relates to a double-clutch-type automatic gearbox parking brake limiting gasket which comprises bolts, a limiting parking pulling rod assembly, a limiting gasket body and a parking fixing block. The double-clutch-type automatic gearbox parking brake limiting gasket is characterized in that the parking fixing block is placed below the limiting parking pulling rod assembly, the limiting gasket body and the parking fixing block are the same in end face shape, and the left side and the right side of the limiting gasket body are fixedly connected to the end faces of the parking fixing block through the two bolts. The limiting gasket body is used, motion of the parking pulling rod assembly is limited, and the double-clutch-type automatic gearbox parking brake limiting gasket has the advantages of being simple in structure, convenient to mount, low in cost and reliable in working.
Description
Technical field
The utility model relates to a kind of double-clutch automatic transmission Parking Brake spacing shim, belongs to the Technology of Automatic Transmission for vehicle field of auto manufacturing.
Background technique
Along with the fast development of automobile pollution and the sharply increase of amateur driver's quantity, automatic gearbox is just presenting fast-developing trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT) and double-clutch automatic transmission (DCT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, is also current most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed to the advantage such as self adaption.But the shortcomings such as it also has complex structure simultaneously, and difficulty is manufactured, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is that efficiency is high, and cost is low, and mature production technology is widely used in China at present.Shortcoming is the gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit becomes possibility.Double-clutch automatic transmission (DCT) is automatic mechanical transmission of new generation, many advantages such as it has inherited that the manual transmission transmission efficiency is high, installing space is compact, lightweight, low price, fundamentally solved the cut-out power shfit problem that electric control mechanical type automatic speed variator exists, greatly improved the gear shift travelling comfort, guaranteed that vehicle has good power character and shift characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer is connected with two clutch C1, C2 arranging on input shaft respectively by strange, even number gear, and clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, vehicle is first with certain gear operation, electrical control unit of automatic transmission (TCU) is about to next gear of the work of entering according to the signal judgement of related sensor, because this gear clutch also separates not transferring power, therefore the instruction hydraulic pressure controlling solenoid valve is controlled gear-shifting actuating mechanism very easily, mesh in advance this gear, when vehicle operating reaches shift point, only need the clutch separation that will work, another clutch is engaged simultaneously, make automobile travel with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure completed like this is power shfit.Vehicle has been realized timing, will improve greatly the gear shift travelling comfort, also guarantees that vehicle has good Economy, and the aspects such as vehicle oil consumption and discharge are made moderate progress simultaneously.
Double-clutch automatic transmission (DCT) Parking rod assembly reciprocatingly slides on fixed block, plays each gear positions of Parking and Parking and engages the effect separated.Design does not in the past adopt spacing shim, and the Parking rod assembly can move up and down in the endoporus of fixed block in the vibration due to car load, produces noise, has affected the NVH effect of car load.
Summary of the invention
The purpose of this utility model is to provide a kind of double-clutch automatic transmission Parking Brake spacing shim, and it adopts spacing shim, has limited the motion of Parking rod assembly, and Ju has that the mono-﹑ An of Jie structure Jian dress Fang Bian ﹑ is with low cost, the characteristics of reliable operation.
The technical solution of the utility model is achieved in that double-clutch automatic transmission Parking Brake spacing shim, by bolt, restriction Parking rod assembly, spacing shim, Parking fixed block, formed, it is characterized in that: the Parking fixed block is positioned at restriction Parking rod assembly below, spacing shim is consistent with the end surface shape of Parking fixed block, and the spacing shim left and right is fixedly connected on Parking fixed block end face by two bolts.
Good effect of the present utility model is that it has compact structure, the characteristics that excellent noise reduction effect and cost are low.
The accompanying drawing explanation
Fig. 1 is the utility model structural drawing.
Fig. 2 is spacing shim structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, 2, double-clutch automatic transmission Parking Brake spacing shim, by bolt 1, restriction Parking rod assembly 2, spacing shim 3, Parking fixed block 4, formed, it is characterized in that: Parking fixed block 4 is positioned at restriction Parking rod assembly 2 belows, spacing shim 3 is consistent with the end surface shape of Parking fixed block 4, and spacing shim 3 left and right are fixedly connected on Parking fixed block 4 end faces by two bolts 1; Restriction Parking rod assembly 2, because the car load generation of vibration moves up and down, reduces vibration and noise, improves the NVH characteristic of car load.
