The plate spring assembly is characterized in that the plate spring assembly consists of a plate spring, a pin shaft and a lining, the width of the front end of the plate spring is different from that of the rear end of the plate spring, the width of the front end of the plate spring is small, the width of the rear end of the plate spring is large, the pin shaft penetrates through a fixed hole in one end of the plate spring and is in clearance fit with the plate spring, the lining is sleeved on the pin shaft and can freely rotate on the pin shaft, and the plate spring and a transmission shell are fixed by a positioning pin. The plate spring assembly has the characteristics of being simple in structure, convenient to install, low in cost and reliable to work.
Description
Technical field
The utility model relates to a kind of double-clutch automatic transmission Parking Brake plate spring assembly, 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).
On automobile, realizing self-shifting speed changer is hydraulic mechanical type automatic transmission, is 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, to resisting moment change can self adaption etc. advantage.But the shortcomings such as it also has complex structure simultaneously, and difficulty is manufactured, and transmission efficiency is low.
Manually fixedly shaft type gear-shift transmission is 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 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 automaitc shfit becomes possibility.Double-clutch automatic transmission (DCT) is automatic mechanical transmission of new generation, many advantages such as it has inherited that 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 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 of this gear clutch separation transferring power not also, therefore 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 the clutch separation of working need to be engaged another clutch simultaneously, make automobile travel with next gear.In gearshift procedure, the power of motor is constantly passed to wheel all the time, so the gearshift procedure completing is like this power shfit.Vehicle has been realized timing, will improve greatly gear shift travelling comfort, also guarantees that vehicle has good Economy simultaneously, and the aspects such as vehicle oil consumption and discharge are made moderate progress.
Double-clutch automatic transmission (DCT) Parking Brake plate spring assembly has the effect that guarantees each gear location and suitable berth-changing strength.At present, the gear of automatic transmission location is general adopts steel ball and spring assembly structure, or gear locating stud; The shortcoming of these mechanisms is to be difficult for installing, and cost is high and processing technology is difficult.This patent Parking Brake adopts plate spring assembly, has the feature of accurate positioning and arrangement convenience.
Summary of the invention
The purpose of this utility model is to provide a kind of double-clutch automatic transmission Parking Brake plate spring assembly, and its Ju has the feature of the with low cost and reliable operation of the mono-﹑ An of Jie structure Jian dress Fang Bian ﹑.
The technical solution of the utility model is achieved in that double-clutch automatic transmission Parking Brake plate spring assembly, it is characterized in that: plate spring assembly is by leaf spring, bearing pin and lining form, and the width front end of leaf spring is different from rear end, and front end width is little, rear end width is large, bearing pin passes the fixed hole of leaf spring one end, and adopts interference fit with leaf spring, and lining is enclosed within on bearing pin, lining can freely rotate on bearing pin, and locating stud is fixed leaf spring and case of transmission.
The utility model good effect is to have Jie structure Jin Cou ﹑ to Ding the feature of the low and reliable operation of position Zhun Que ﹑ cost.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is exploded view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as Fig. 1,, shown in 2, double-clutch automatic transmission Parking Brake plate spring assembly, it is characterized in that: plate spring assembly is by leaf spring 1, bearing pin 2 and lining 3 form, the width front end of leaf spring 1 is different from rear end, front end width is little, rear end width is large, bearing pin 2 passes the fixed hole of leaf spring 1 one end, and adopts interference fit with leaf spring 1, and lining 3 is enclosed within on bearing pin 2, lining 3 can freely rotate on bearing pin 2, and locating stud 4 is fixed leaf spring 1 and case of transmission.
The purposes of plate spring assembly is that each grade of parking P ﹑ R ﹑ N ﹑ D ﹑ S had to positioning action, and produces gear shift feel, therefore, the size of its power produces vital effect to the travelling comfort of shifting of transmission, in addition, this patent has also adopted locating stud, plays the effect that prevents that leaf spring from rotating.The utlity model has Jie structure Jin Cou ﹑ accurate positioning and the low feature of cost.
