Description
Technical field
The present invention relates to a kind of automobile parking lockable mechanism, be specifically related to a kind of parking locking mechanism that is used for the automobile double clutch automatic gearbox.
Background technique
Good halting mechanism is the important means that ensures the reliable Parking of automobile, the car of existing configuration manual transmission, and speed changer inside does not have halting mechanism, and car load adopts conventional parking brake system to carry out Parking; In the car of dress with automatic transmission, the inner general special halting mechanism of all having adorned of speed changer.
Japan Toyota has proposed a kind of keying structure of electronic eccentric shaft structure in patent application document CN101611248A " halting mechanism of automatic transmission "; Lucky patent documentation CN201723694U " a kind of automatic gearbox electric-controlled hydraulic parking and braking mechanism " has proposed a kind of keying structure of hydraulic control; Though they have improved level of integration and automaticity; But increased automatic executing agency; It is complicated more that halting mechanism becomes, and reduced the reliability of system.
Propose to adopt the internal clickwork gear ring and the mode of outer ratchet engaged to brake among the patent documentation CN200920314687.0 of lucky company " a kind of halting mechanism of automatic gearbox "; Braking is reliable; Reduced the load on the single hook tooth, but this kind structure more complicated, cost is high.Therefore be necessary to combine the requirement of double-clutch automatic gearbox to design the simple relatively parking device of a kind of structure.
Summary of the invention
The object of the present invention is to provide a kind of simple, manual control, double-clutch automatic speed-change halting mechanism with low cost.
The present invention seeks to realize through following technological scheme:
The halting mechanism of a kind of double-clutch automatic speed-change case that the present invention relates to mainly is made up of Parking Rocker arm assembly, Parking connecting rod ASSY, park pawl assembly, Parking gear, Parking limiting stopper etc.
Parking Rocker arm assembly one termination shift handle wherein, another termination Parking connecting rod ASSY, the Parking connecting rod ASSY passes the Parking limiting stopper and contacts with the park pawl assembly, be positioned at during non-Parking park pawl above.Park pawl pin and return spring are installed on the park pawl; Park pawl in park pawl assembly park pawl pin is relatively rotated, and under the effect of Parking connecting rod, park pawl can relatively rotate around bearing pin; Impel pawl teeth portion to get in the Parking gear tooth slot of pairing, accomplish Parking.
When the needs Parking; The pilot control gear shifting handle drives the motion of Parking rocking arm, and drives the to-and-fro motion in the Parking limiting stopper of Parking connecting rod ASSY, and the Parking connecting rod ASSY of connection passes the Parking limiting stopper and contacts with corresponding pawl structures; Thereby promote the park pawl rotation; Make park pawl and Parking gear engagement, stop the rotation of final gear, realize Parking.When the driver stirs shift handle, when withdrawing from parking braking, shift handle drives the motion of Parking rocking arm; The Parking bar linkage structure is moved upward, reduce and eliminate gradually acting on the pressure on the park pawl, park pawl is under the effect of return spring; Move round about around detent pin; Ratchet is withdrawed from and the Parking gear meshing, remove Parking effect, the also corresponding recovery normal operation of car load final gear.
Beneficial effect of the present invention is: in double-clutch automatic gearbox, adopt gear shifting handle to drive rocking arm, receive the Parking connecting rod of Parking limiting stopper restriction through interlock; Promote park pawl and Parking gear engagement, realize Parking, transmission line is simple; Simple in structure, compact reliable, with low cost.
Description of drawings
Fig. 1 is the structure and the schematic diagram of double-clutch automatic speed-change case parking locking mechanism;
Fig. 2 is a Parking connecting rod ASSY structural drawing;
Fig. 3 is the park pawl assembly structure chart;
Fig. 4 is Parking rocker structure figure.
Embodiment
Below in conjunction with accompanying drawing double-clutch transmission mechanism embodiment of the present invention is done further detailed description:
In conjunction with Fig. 1 ~ Fig. 4, can find out:
Parking gear 1 is for being uniformly distributed with the gear of tooth punching around the ring-type, the main reducing gear gearwheel (omission is not drawn among the figure) in general and the differential mechanism is fixedly connected.
Park pawl 21 is fixed on respective design position in the mission case (omit among the figure and do not draw) through park pawl positioning plate 23 and park pawl locating stud 22; Wherein park pawl pin 22 is installed in the pin-and-hole of park pawl 21 1 ends and with casing and is connected; Park pawl positioning plate 22 is installed on the park pawl pin 23, and with park pawl 21 axial restraints, said park pawl 21 can be around 23 rotations of park pawl locating stud; Park pawl return spring 3 one ends are connected with park pawl 21; The other end is connected with park pawl return spring fixed plate 4, and park pawl return spring fixed plate 4 is fixed on the mission case, and park pawl return spring 3 has initial pretightening force; Can prevent the error Parking that park pawl 21 is caused by slight vibration, return spring is used for park pawl the resetting of ratchet under non-Parking condition.
Parking connecting rod ASSY 6 can to-and-fro motion in said Parking limiting stopper 5, in the Parking connecting rod ASSY 6 Parking cam 63 be positioned at park pawl 21 above, can promote park pawl 21 during Parking around 23 rotations of park pawl locating stud.
Parking rocking arm 71 has been formed Parking Rocker arm assembly 7 jointly with rocker arm support 72, and Parking rocking arm 71 is installed on the rocker arm support 72, and Parking rocking arm 71 1 ends are connected with gearshift mechanism (omit among the figure and do not draw), and the other end is connected with Parking connecting rod ASSY 6.
When automobile normally moved, park pawl 21 disengaged with Parking gear 1 under the effect of park pawl return spring 3, and automobile can freely be advanced.When needs are braked; The driver controls Joystick to the Parking position; Drive 7 rotations of Parking Rocker arm assembly; Move downward in Parking limiting stopper 5 thereby drive Parking connecting rod ASSY 6, inwardly rotate, make park pawl 21 progressively near Parking gear 1 through the pushed park pawl at park pawl back; When the tooth portion of park pawl 21 gets in the mark of mouth groove of Parking gear 1, park pawl 21 Parking cam 63 and Parking limiting stopper 5 and gearbox on locking mechanism (not drawing among the figure) effect limit in the Parking position; When park pawl 21 and Parking gear 1 tooth top are inconsistent; Parking cam 63 is limited; Parking return spring 62 is compressed, and gives Parking cam 63 and 21 1 lasting Parking driving forces of park pawl, until angle of Parking gear 1 rotation; Till making park pawl 21 snap in the groove of Parking gear 1, accomplish Parking.
When needs are removed Parking; The driver controls Joystick to normal road location, drives 7 counterrotatings of Parking Rocker arm assembly, moves upward in Parking limiting stopper 5 thereby drive Parking connecting rod ASSY 6; Parking cam 63 gradually reduces the Parking active force on the park pawl 21 that leans against; Park pawl 21 is return under the effect of ratchet return spring 3, withdraws from the engagement with Parking gear 1, thereby removes Parking.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technological scheme of the present invention all should fall into the protection domain that claims of the present invention are confirmed.
