The objective of the invention is, have the bigger shortcoming of bornologic space to the KRG speed changer, simplified system improves reliability and expanding governing, discloses a kind of novel CRT (Cone Ring Transmission) conical ring formula transmission system.
The novel CRT of patent of the present invention (Cone Ring Transmission) speed changer is the improved a kind of novel stepless speed variator on KRG speed changer basis.
Fig. 2 is the basic functional principle figure of novel CRT speed changer, also is made up of 1,3 and steel loops 2 of two work cones.The axis of two work cones 1,3 is parallel to each other, and holds positioned opposite greatly, axis misalignment certain distance (be because " steel loop " and " work cone " do not produce physical intervention needed).The element of cone in two work cone 1,3 outsides is parallel to each other.The steel loop 2 of rigidity is encircled in the outside (rather than being clipped in the middle) of two work cones 1,3, with the outer side surface working bus bar connecting part generation frictional force of two work cones 1,3.Because steel loop 2 receives the effect of two tangential peripheral force of work cone 1,3 in transmitting torque; These two tangential peripheral force are pointed to the same side direction; Promote steel loop 2 and depart from two work cone 1,3 center line plane; Thereby produce working surface contact impacting force automatically, this impacting force is directly proportional with the moment of torsion that is transmitted.The impacting force that the rigidity of steel loop 2 and whole system will determine to be produced and the size of circumference tangential force guarantee that from the rigidity Design of steel loop 2 friction driving normally carries out needed automatic impacting force, make it not produce and skid.This generation makes that from the mechanism of compaction forces the structure of speed changer is more simple and reliable.When steel loop 2 when two work cone 1,3 outside generatrix directions move, change the initiatively radius of clean-up of cone pulley and passive cone pulley, reach the continuous stepless speed change.
The technological scheme that realizes the object of the invention is, novel CRT conical ring formula transmission system of the present invention by transmission steel loop 11, initiatively cone pulley 12, gearshift actuation gear 13, planet wheel changement 14, switching-over shift fork 15, fixedly end face ring gear 16, input shaft 17, slide block ring gear 18, planet wheel external toothing 19 commutate; Splined shaft 20; Circlip 21, passive cone pulley 22, output shaft 23, rotation shift fork 24 and 25 compositions of rotation guide rail.Input shaft 17 is sun gears of planet wheel changement 14, and planet wheel changement 14 can be realized the switching of neutral, reverse gear and forward gear; Planet wheel external toothing 19 and splined shaft 20 fixed-link, initiatively cone pulley 12 is installed on the splined shaft 20 and rotates with planet wheel outer tooth ring 19.
Initiatively the axis of cone pulley 12 and passive cone pulley 22 is parallel to each other the certain distance but two axial lines staggers; Passive cone pulley 22 is installed on the output shaft 23, and initiatively cone pulley 12 contacts with the inner cylindrical surface of transmission steel loop 11 with passive cone pulley 22.Drive transmission steel loop 11 when initiatively cone pulley 12 rotates and rotate, transmission steel loop 11 drives passive cone pulley 22 again and rotates, and has realized the transmission of rotation motion.
Have the groove of annular to match with rotating shift fork 24 on transmission steel loop 11 external cylindrical surfaces, the rectangular guideway groove that rotates shift fork 24 is enclosed within and rotates on the guide rail 25 and can move along guide rail direction straight line.When under rotation guide rail 25 externally drives, making left-right rotation, drive rotation shift fork 24 and transmission steel loop 11 and also make left-right rotation.The central plane of transmission steel loop 11 is perpendicular with the element of cone of active cone pulley 12 and passive cone pulley 22 originally; This time, steel loop was with transmission rotating speed and moment of torsion as you were; When rotating guide rail 25 left-right rotation, make the central plane of transmission steel loop 11 turn an angle with respect to the vertical plane of the element of cone of active cone pulley 12, passive cone pulley 22, be equivalent to vehicle front and do steering angle; Make transmission steel loop 11 when transmitting rotating speed and moment of torsion; Along the cone pulley bus do a left side or right-hand to straight line move, thereby changed the initiatively radius of clean-up of cone pulley 12, passive cone pulley 22, realize stepless change.
The planet wheel changement is as shown in Figure 8.
If switching-over slide block ring gear 18 mediates, it only follows planetary carrier 26 rotations, and input shaft 17 drives planetary carrier 26 idle running, and power can't be delivered on the splined shaft 20, and corresponding is the neutral state.
When switching-over slide block ring gear 18 moves round about, make profile of tooth and fixedly end face ring gear 16 interlock mutually on its end face.Fixedly end face ring gear 16 is fixedly mounted on the case of transmission, and such interlock makes planetary carrier 26 be in the fixing state that does not change, and sun gear drives planet wheel external toothing 19 through planetary pinion and does oppositely to slow down to rotate, and corresponding is the reversing state.
" tight round nut with lock " process " butterfly spring " compresses cone pulley 12 initiatively from axial direction and makes it to produce the initial contact pressure with transmission steel loop 11.In case the generation transmitting torque, transmission steel loop 11 will produce the contact pressure that is directly proportional with moment of torsion automatically, to guarantee the safe operation of friction driving.
The novel CRT transmission system is by gearbox control (TCU) control, and the relative position of TCU through gearbox no-load voltage ratio control executing mechanism step-less adjustment transmission steel loop (11) is to reach desirable gear ratio.
Figure 11 is the control block diagram of CRT.Gearbox control is the brain of CRT.Car and information of road surface that TCU collection cart set sensor provides; Accept the useful information that other automatical control system sends through the CAN bus on the car; Also accept driver's control command, according to the best velocity ratio of decision gearboxes such as the best durability of optimum oil consumption, best power performance, optimum drive travelling comfort and system.
