Description
Technical field
The present invention relates to the automotive compounded speed changer of a kind of roller type, belong to automotive field.
Background technique
Existing automotive transmission comprises mechanical transmission, automatic transmission, auto-manual transmission and stepless speed variator, and CVT (Continuously Variable Transmission) speed changer has become current development of automobile speed changer faster.Cart-wheel stepless speed variator continuously changes velocity ratio by changing the effective diameter size of the master and slave Moving plate position of roller contact in certain number range, has the advantages such as compact structure, reliable operation, stable drive, noise are low.But because the velocity ratio excursion of cart-wheel stepless speed variator is little, not also being applied on automobile.
Summary of the invention
In order to overcome the deficiency of existing speed changer, the object of this invention is to provide the automotive compounded speed changer of a kind of roller type, it has the advantage of cart-wheel stepless speed variator and mechanical transmission, automobile realizes roller type variable transmission when 0 ~ 60km/h travels, when automobile is automatically converted to low speed or high speed machine gear transmission when more than 60km/h travels, thus overcome the deficiency of cart-wheel stepless speed variator and mechanical transmission, raise the efficiency, reduce discharge.
The present invention realizes by following measures: on the roller type infinitely variable speed transmission basis that driving disc, roller, driven disc and planetary gear set are formed, have additional a grade speed change gear.Automobile is when 0 ~ 60km/h travels, roller type infinitely variable speed transmission works, roller presses to and drives driven disc to rotate by driving disc, low-grade step change clutch and high-grade step change clutch separation, power exports through the gear of output end deceleration of input shaft, driving disc, roller, driven disc and planetary gear set, then drives main reducing gear driven gear through low speed gear and jack shaft; By changing four rolling and driving disc, the effective diameter size of contact position of driven disc changes the transmission speed ratio of master and slave Moving plate, thus realizes roller type stepless change; When automobile is more than 60km/h, step change transmission operation, low-grade step change clutch and high-grade step change clutch engage, power through input shaft, low-grade step change clutch or high-grade step change clutch, low speed gear, have jack shaft, drive main reducing gear driven gear, realize low or high speed step change.
The invention has the beneficial effects as follows, combine the advantage of roller type variable transmission and mechanical speed change transmission, decrease cart-wheel stepless speed variator at a high speed large load time power loss, reduce energy consumption and operation easier when mechanical transmission low speed complex road condition travels, improve transmission efficiency and reliability, reduce discharge.

Embodiment
for the technical characterstic of this programme can be clearly demonstrated, below by embodiment, and by reference to the accompanying drawings, this programme is set forth.
The automotive compounded speed changer of a kind of roller type, forms primarily of fore shell 1, mesochite 6, back cover 7, driving disc 2, front retainer 3, rear retainer 4, driven disc 5, planetary gear set 8, low-grade step change clutch 9, high-grade step change clutch 10, high-grade gear 11, servovalve 12, input shaft 13, jack shaft 14, low speed gear 15, differential mechanism 16, main reducing gear driven gear 17, synchronous cone gear 18, sliding bearing 19, turning rolls 20, roller shaft 21, roller 22, stepless change Control Shaft 23, U-shaped plate 24, circlip 25.
Input shaft 13 left end and driving disc 2 are connected, and are connected with motor by damping disk(-isc) and flywheel; Driven disc 5 and planetary gear set 8 are fixed together and are supported on mesochite 6 and can rotate at input shaft 13; Hold front retainer 3 and rear retainer 4 between fore shell 1 and mesochite 6, forward and backward retainer is equipped with turning rolls 19 by sliding bearing 18, and turning rolls 19 two ends are fixed wtih synchronous cone gear 17; Roller 21 is contained on turning rolls 19 by roller shaft 20; Transmission stepless gear Control Shaft 23, controls turning rolls 19 and synchronous cone gear 17 drives four rolling 21 along the axis synchronous axial system of input shaft 13; When servovalve 12 enters piston cavity promotion driving disc 2 by hydraulic oil through oil duct, four rolling 21 is pressed on driven disc 5, and the transmission speed ratio of master and slave Moving plate is changed by the contact position changing four rolling 21 and driving disc 2 and driven disc 5, by the gear of output end driver output of planetary gear set 8, realize its stepless change.
The spline of input shaft 13 right-hand member and low-grade step change clutch 9 and high-grade step change clutch 10 fixed base is connected, the low-grade secondary part of step change clutch 9 and the gear of output end end of planetary gear set 8 are connected, and secondary part and the high-grade gear 11 of high-grade step change clutch 10 are connected; When servovalve 12 hydraulic fluid pressure reduces, the belleville spring be contained on input shaft 13 promotes driving disc 2 and moves to left, make being separated of driving disc 2 and driven disc 5, servovalve 12 carrys out the Engage and disengage of low-grade step change clutch 9 and high-grade step change clutch 10 by hydraulic oil simultaneously; When low-grade step change clutch 9 engages, high-grade step change clutch 10 is separated, input shaft 13 drives planetary gear set 8, low speed gear 15 and jack shaft 14 to drive main reducing gear driven gear 17 to realize low speed step change through low-grade step change clutch 9; When high-grade step change clutch 10 engages, low-grade step change clutch 9 is separated, input shaft 13 directly drives jack shaft 14 to drive main reducing gear driven gear 17 to realize high speed step change through high-grade step change clutch 10.
When automobile travels in 0 ~ 60km/h vehicle speed range, roller type infinitely variable speed transmission works.Now the power of motor passes to input shaft 13 by flywheel and damping disk(-isc), now low-grade step change clutch 9 is separated with high-grade step change clutch 10, power exports through the gear of output end deceleration of input shaft 13, driving disc 2, roller 21, driven disc 5 and planetary gear set 8, then drives main reducing gear driven gear 17 through low speed gear 15 and jack shaft 14; Transmission stepless gear Control Shaft 22, controls turning rolls 19 and synchronous cone gear 17 drives four rolling 21 along the axis synchronous axial system of input shaft 13; When servovalve 12 enters piston cavity promotion driving disc 2 by hydraulic oil through oil duct, four rolling 21 is pressed on driven disc 5, and changed the transmission speed ratio of driving disc 2 and driven disc 5 by the effective diameter of the contact position changing four rolling 21 and driving disc 2 and driven disc 5, thus realize the adjustment of roller type variable transmission speed ratio.
When automobile travels with 60km/h and the above speed of a motor vehicle, step change transmission operation.Now servovalve 12 hydraulic fluid pressure reduces, the belleville spring be contained on input shaft 13 promotes driving disc 2 and moves to left, make being separated of driving disc 2 and driven disc 5, servovalve 12 is separated by the joint of the next low-grade step change clutch 9 of hydraulic oil, high-grade step change clutch 10 simultaneously, and engine power drives main reducing gear driven gear 17 to realize low speed step change through input shaft 13, low-grade step change clutch 9, planetary gear set 8, low speed gear 15 and jack shaft 14; When high-grade step change clutch 10 engage, low-grade step change clutch 9 be separated time, engine power directly drives jack shaft 14 to drive main reducing gear driven gear 17 to realize high speed step change through input shaft 13, high-grade step change clutch 10.
