Abstract

The utility model relates to a mechanical transmission and particularly relates to a suspended bevel gear stepless transmission which adopts a suspended bevel gear mechanism in a vehicle transmission system. Main parts comprise an input shaft (1), a suspended planet carrier (2), a support sleeve (3), an input bevel gear (4), a planet bevel gear (5), a torque transfer shaft (6), a driving bevel gear (7), an output bevel gear (8), an output shaft (9), a starting clutch (13) and a housing (14), wherein the torque of the input bevel gear (4) is processed by the planet bevel gear (5), the torque transfer shaft (6) and the driving bevel gear (7), then the torque of the output bevel gear (8) is increased, and the output shaft (9) is further pushed, so that the maximum torque can be output at low speed; after the load is reduced, the suspended bevel gear mechanism can push in a revolution way and output the highest rotational speed, and the pure mechanical stepless transmission function is further completed; and furthermore, the structure is very simple, the price is very low, the transmission is greater than continuous bearing force, and the stepless transmission is further safe, reliable and long in service life.

Description

Awl tooth road wheel stepless speed variator suspends

Technical field

The present invention relates to a kind of mechanical speed changer, relate in particular to a kind of awl tooth road wheel mechanism that in vehicle drive system, adopt to suspend and realize that torsion shifts and increase suspension awl tooth road wheel stepless speed variator that the square characteristic promotes output with it.

Background technique

The automatic Transmissions Technique of more use is the automatic transmission technology with fluid torque converter and epicyclic train combination on automobile at present, but it has significant disadvantages: velocity ratio is discontinuous, and hydraudynamic drive efficient is lower; Complex structure is safeguarded inconvenience, a kind of in addition stepless change (CVT); Its adopts metal driving belt and the variable driven wheel of the working diameter incompatible transferring power that matches, but the CVT weakness is that the metal tape bearing capacity is little, and transmitted power is limited; And the cost long-life is short; Its control system is quite complicated, causes supplementary costs to increase, and can only be used for car at present.Therefore, develop a kind of safe and reliable, simple in structure, easy to process and cheap stepless speed variator, just become mechanical industry urgent problem in decades.The present invention adopts to suspend and bores tooth road wheel mechanism and realize that with it torsion increases the suspension awl tooth road wheel stepless speed variator of square; When work directly according to load variations; Fully automatically carry out stepless change moment of torsion variable speed running, the present invention does not see homogeneous structure product and related data both at home and abroad.

Summary of the invention

Problem to be solved by this invention provides the accurate tooth road wheel of a kind of suspension stepless speed variator; It is in operation, and adopting suspends bores tooth road wheel mechanism and increases the square characteristic with it; With the torsion of input small gear through the awl tooth road wheel that suspends shift increase square to the output bevel gear after, promptly practicable speed changer is accomplished the running of stepless shift function ground reliably between Maximum Torque and maximum speed.

The present invention is achieved in that in Fig. 1: suspension is bored tooth road wheel stepless speed variator main parts size and is comprised input shaft 1, suspension planet carrier 2, carrying sleeve 3, input bevel gear 4, bevel planet gear 5, torsion transfer shaft 6, drives bevel gear 7, output bevel gear 8, output shaft 9, the bevel gear 10 of moveing backward, reverse clutch 11, input clutch 12, start clutch 13, casing 14 compositions; Its structure is: input shaft 1 is with output shaft 9 coaxial lines and by casing 14 supportings; The front portion of reversing bevel gear 10 through reverse clutch 11 and input shaft 1 is (before establishing casing 14 interior input ends and being; Output terminal is the back) carry out to separate and combine; Input bevel gear 4 is carried out through the rear portion of input clutch 12 and input shaft 1 and separates and combine; Suspension planet carrier 2 is by input shaft 1 and output shaft 12 supportings; Suspension planet carrier 2 separates through start clutch 13 and casing 14 implementations and combines; Also circumferential five equilibrium ground just has been associated with several carrying sleeves 3 on the suspension planet carrier 2; Be installed in the carrying sleeve 3 with the torsion transfer shaft 6 of carrying sleeve 3 equal numbers and with its Spielpassung; One end of torsion transfer shaft 6 just has been associated with bevel planet gear 5; Bevel planet gear 5 and input bevel gear 4 and 10 engagements of reversing bevel gear; The other end that torsion transfer shaft 6 is passed behind the carrying sleeve 3 has just joined with driving bevel gear 7; Drive bevel gear 7 and 8 engagements of output bevel gear; Bevel gear 8 has just joined with output shaft 9 in output.

The awl tooth road wheel stepless speed variator working principle that suspends is referring to Fig. 1 and Fig. 2: in Fig. 1; During reversing; Start clutch 13 with suspension planet carrier 2 combine with casing 14, reverse clutch 11 bevel gear 10 of will moveing backward combines with input shaft 1, reversing bevel gear 10 drives bevel planet gears 5, torsion transfer shaft 6, drives bevel gear 7 and then drives 8 counter-rotatings of output bevel gear and can move backward; When advancing; Start clutch 13 earlier with suspension planet carrier 2 combine with casing 14, suspension planet carrier 2 rotating speeds are zero; Import then that bevel gear 4 is just changeing and through bevel planet gear 5, torsion transfer shaft 6, drive bevel gear 7 and directly drive output bevel gears 8 and just changeing, starting to walk after; Its stepless change principle of available Fig. 2 simplified illustration: separate after 14 startings of suspension planet carrier 2 and casing; The moment of torsion of then importing bevel gear 4 is except that giving 5 one rotation torques of bevel planet gear; Input bevel gear 4 can also directly suspend planet carrier 2 and the carrying sleeve 3 that is installed on it, bevel planet gear 5, torsion transfer shaft 6, drive 7 one revolution of bevel gear torsion, since at the bottom of the awl of output bevel gear 8 circle radius be circle radius at the bottom of the awl of input bevel gear 4 N doubly; Then exporting bevel gear 8 can drive output shaft 9 with the moment of torsion that N doubly imports bevel gear 4 and increase square and rotate; Be exportable Maximum Torque this moment, and no matter output shaft 9 rotating speeds what, the torsion of input bevel gear 4 can both put on the output bevel gear 8 and increase and drive output shaft 9 behind the square through revolution; Therefore the output speed that reduces rear output shaft 9 when load will speed thereupon; Until the output speed of the revolution rotating speed of suspension planet carrier 2 and output shaft 9 input speed of convergence input bevel gear 4 all, output this moment promptly be maximum speed, thereby speed changer is accomplished stepless shift function reliably between Maximum Torque and maximum speed.

Suspension of the present invention awl tooth road wheel stepless speed variator because the awl tooth road wheel mechanism that suspends is used in innovation, makes it can be in the output Maximum Torque;, load can also export maximum speed after reducing; Thereby accomplished the mechanical stepless speed-changing function reliably, and textural anomaly is simple, price is very cheap; Velocity ratio continuous bearing power is big, and the safe and reliable spreadable life is long.
