A friction device is installed on shaft heads of two intermediate shafts. The speed changer brake is rapid in brake response speed, stable and big in strength.
Description
Technical field
The utility model relates to the transmission for vehicles field, relates in particular to the speed changer brake based on clutch actuating mechanism.
Background technique
At present, all comprise a break in the commercial car AMT both domestic and external system.Break is used for vehicle start when upgrading, and one and the transmission part that is associated are carried out braking deceleration, to shorten lock in time, reduces shift impact.The break that is used for AMT according to different design and installations in force taking window of speed variator mouth or jack shaft spindle nose place.Drive form mainly contains electromagnetism, hydraulic pressure and pneumatic three kinds of forms.The break of these three kinds of forms needs special actuator to drive, and pluses and minuses are respectively arranged.The electromagnetic brake response is fast, but complex structure.Hydraulic pressure and pneumatic braking device low-response, and have the oil and gas leakage problem.
The model utility content
In order to solve existing technical problem in the background technique, the utility model provides a kind of speed changer brake based on clutch actuating mechanism, rubbing device is installed on two jack shaft spindle noses.Braking response is quick, steadily and intensity big.
The technical solution of the utility model is: based on the speed changer brake of clutch actuating mechanism; Its special way is: the sensing drive unit that said speed changer brake comprises clutch release bearing, be connected with clutch release bearing and be arranged on transmission countershaft and case of transmission between braking device, said sensing drive unit and braking device are adaptive.
Above-mentioned sensing drive unit is a brake holder, and said brake holder is fixedly connected with brake piston.
Above-mentioned sensing drive unit comprises sensing unit and driver element, and said sensing unit is the sensor that cooperates with clutch release bearing; Said driver element is hydraulic pressure or the electromagnetic drive mechanism adaptive with braking device.
Above-mentioned braking device comprises brake piston and the friction pair adaptive with brake piston, and said brake piston is connected with the sensing drive unit.
Above-mentioned friction pair is the friction pair of a plurality of friction plates compositions or the friction pair of the conical surface on the piston and the conical surface adaptive brake on the jack shaft.
Above-mentioned a plurality of friction plate comprises one group of brake strip and one group of braking steel disc; Space on said brake strip and the braking steel disc axial direction; Said brake strip or braking steel disc cooperate through spline or keyway with clutch housing, and said braking steel disc or brake strip cooperate through spline or keyway with jack shaft.
Between above-mentioned brake piston and the brake intermediate shaft pressure spring is set, said pressure spring is arranged in the hole on the jack shaft.
Between above-mentioned pressure spring and the jack shaft spring housing is set, said spring housing is the volute spring cover.
The top of above-mentioned spring housing is connected with brake piston, and the side of said spring housing closely is connected with hole on the jack shaft.
The utility model is a kind of speed changer brake design proposal; Speed changer brake based on clutch actuating mechanism has been proposed; Cancel the special-purpose actuator of existing break, utilized clutch actuating mechanism to drive clutch release bearing and drive, need not special break driving mechanism; Reduce cost, reduced the fault point.Also need not to be directed against specially the electric driver module of break.Can select according to actual needs simultaneously arbitrary jack shaft or two jack shaft brakings, mode of braking is flexible.
Braking device is installed on two jack shaft spindle noses, and braking response is quick, steadily and intensity big.Because the AMT clutch actuating mechanism is high to the control accuracy of power and stroke, therefore driven break braking is steady and braking force is adjustable within the specific limits.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 .1, Fig. 2 .2 are the structural representations of the utility model medi-spring cover;
Embodiment
Referring to Fig. 1, the speed changer brake based on clutch actuating mechanism of the utility model comprises clutch release bearing 1, brake holder 2, brake piston 3, brake strip 4, braking steel disc 5, spring housing 6 and pressure spring 7; Brake piston 3, brake strip 4, braking steel disc 5 constitute braking device, and braking device is installed on two jack shaft spindle noses.Brake strip 4, braking steel disc 5 constitute a friction pair.
The mode of brake holder 2 can be not limited to this mechanical structure, also can adopt the mode of electronic sensor and hydraulic driving or Electromagnetic Drive, as long as realize clutch release bearing the driving of brake piston just can.Friction pair also can adopt the form of cone of friction, promptly through the adaptive completion braking of the conical surface on the piston conical surface and the jack shaft.Brake strip 4 is nonmetallic material, and braking steel disc 5 is metallic material.Between said brake piston and the jack shaft pressure spring is set; Pressure spring is provided with spring housing 6, and said pressure spring and spring housing 6 are nested in the hole on the jack shaft, and spring housing 6 is volute spring covers; The top of spring housing 6 and brake piston 3 contact matching; The concrete structure of spring housing 6 is referring to Fig. 2 .1, Fig. 2 .2, and the volute spring cover is the cylindrical spring cover that has tapered tip, and the top of volute spring cover is plane or sphere; The top of volute spring cover is a sphere among Fig. 2 .1, and the top of volute spring cover is the plane among Fig. 2 .2.
The speed changer brake based on clutch actuating mechanism of the utility model; After the clutch separation; Think and to brake transmission input shaft like the AMT system, then continue to promote clutch release bearing 1 and move to direction away from motor through clutch actuating mechanism.At this moment clutch release bearing 1 can promote brake holder 2, and brake holder 2 and two brake pistons 3 use bolton, so brake holder 2 can drive brake pistons 3 and move right together, thereby compresses brake strip 4 and brake steel disc 5.Braking steel disc 5 is fixed together with clutch housing; Brake strip 4 rotates through spline and jack shaft engagement; Therefore when brake strip 4 with brake steel disc 5 compacted the time; Between braking steel disc 5 and brake strip 4, just produced friction torque, this friction torque just can be carried out braking deceleration to jack shaft.When the AMT system thought that Braking efficiency reaches requirement, solenoidoperated cluthes actuator also drove clutch release bearing 1 and moves to the direction near motor.The active force of 1 pair of brake holder 2 of clutch release bearing will disappear.At this moment, pressure spring 7 will promote brake piston 3 left with spring housing 6.The disappearance of positive pressure the time, also eliminated braking force between brake piston 3 and the friction pair to jack shaft.
