Described parking base is arranged on the internal face of case of transmission, and the cross section of this parking base and housing matching part is circular and in the installation hole slot that is fitted on the internal face of case of transmission of interference.
Described park pawl is provided with return spring and detent pin, wherein: the two ends of detent pin are supported by case of transmission, one end of return spring is buckled in park pawl, and the other end is stuck on case of transmission as return torsion spring, and often pushes described park pawl to off-position.
The described pin that performs utilizes the pretightning force of preloading spring to be arranged on push rod, and push rod one end is connected in rocker plate, and the other end contacts with parking base with performing pin.
By the main speed reducing ratio subtracting gear pair, locking demand torque is reduced；Locking power is caused on case of transmission by guiding execution pin conduction simultaneously rather than act on shifting shaft.
Technique effect
Compared with prior art, this utility model guide plate is snapped on parking base, parking base press-fits on case of transmission, this kind of structure decreases number of parts, and need not bolt and fix parking base or guide plate, reduce loosening risk, decrease the space taking variator, reduce assembly cost simultaneously.Guide plate is punching press plate, its from perform pin gap and can need to carry out bending according to different gears and adjust, the kinestate performing pin under different gears is accurately guided, it is to avoid the problem of the part gear steering capability difference that single shape causes.Particularly, guide plate with perform the gap that pin keeps minimum when D keep off, with ensure vehicle when advancing, execution pin will not rock in guide plate and make a noise.Guide plate is sheet member, has an elasticity, reduces further to perform under non-P gear state to sell and rocks noise in guide plate.

Detailed description of the invention
As shown in Figure 1, the present embodiment includes: the parking gear 1 being arranged on transmission countershaft, the park pawl 2 being meshed with parking gear 1, for the execution pin 3 driving park pawl 2 to engage with parking gear 1, for guiding the guide plate 4 performing pin 3 motion and for carrying the parking base 5 performing pin 3 stress, wherein: guide plate 4 is connected on parking base 5, perform pin 3 through guide, one end of park pawl 2 is socketed with detent pin and rotates around detent pin, the other end rotates and is arranged at inside variator, and this park pawl 2 the lock position engaged with parking gear 1 and and the off-position that departs from of parking gear 1 between rotatable.
As it is shown in figure 1, the middle part of described rocker plate 8 is connected with rocker arm shaft 7, rocker plate 8 one end is connected with push rod 12, and the other end is provided with detent, and this detent is coordinated be accurately positioned gear positions by the row's pin 14 of determining being fitted on case of transmission with interference.
Described rocker arm shaft 7 is through case of transmission, and its one end is connected with rocker plate 8, and the other end is connected with drag-line plate 10, and drag-line plate 10 is connected with drag-line ball 9.
As shown in Figure 2, described parking base 5 is arranged on the internal face of case of transmission, this parking base 5 and the cross section of housing matching part are circular and in the installation hole slot that is fitted on the internal face of case of transmission of interference, so can significantly reduce number of parts, and need not bolt and fix parking base or guide plate, reduce loosening risk, decrease the space taking variator, reduce assembly cost simultaneously.
As it is shown on figure 3, described guide plate is for having resilient thin wall punching press plate, rocking noise with execution pin under the non-P gear state of minimizing further in guide plate, this guide plate can be snapped on parking base by hand, easy to assembly.
There is between the card buckle of described guide plate and parking base circumferential Yu axial good fit location, it is ensured that guide will not rotate or come off in the course of the work；And guide plate and execution pin gap can need to carry out bending according to different gears and adjust, the kinestate performing pin under different gears is accurately guided, it is to avoid the problem of the part gear steering capability difference that single shape causes.
Particularly, guide plate with perform the gap that pin keeps minimum when D keep off, with ensure vehicle when advancing, execution pin will not rock in guide plate and make a noise.
As shown in Figure 1 and Figure 4, described park pawl 2 is provided with return spring 6 and detent pin 13, wherein: the two ends of detent pin 13 are supported by case of transmission, one end of return spring 6 is buckled in park pawl, the other end is stuck on case of transmission as return torsion spring, and often pushes described park pawl 2 to off-position.
As it is shown in figure 5, the described pin 3 that performs utilizes the pretightning force of preloading spring 11 to be arranged on push rod 12, push rod 12 one end is connected in rocker plate 8, and the other end contacts with parking base 5 with performing pin 3.
Guide plate in this device accurately can guide according to the kinestate performing pin under different gears, avoid the problem of part gear steering capability difference in prior art, guide plate keeps the gap of minimum with performing pin when D keeps off, with guarantee vehicle when advancing, parking push rod will not rock in guide plate and make a noise；Parking base can directly be press-fitted on case of transmission in interference, and number of parts is few, takes up room little, and easy to assembly, function is reliable.
This device subtracts the speed reducing ratio of gear pair by master, and by the reduction of locking demand torque, locking power is conducted to case of transmission by guiding to perform to sell simultaneously, will not act on shifting shaft, and therefore gearshift rotates easily, and shift-feel is good；Additionally, this device can carry out parking action to use tradition drag-line mode, it would however also be possible to employ electric device or hydraulic means carry out action, electric device or hydraulic means or pneumatic means can be hung on outward outside variator, are not take up variator inner space.
Above-mentioned being embodied as can be carried out local directed complete set to it by those skilled in the art on the premise of without departing substantially from this utility model principle and objective in a different manner; protection domain of the present utility model is as the criterion with claims and is not limited by above-mentioned being embodied as, and each implementation in the range of it is all by the constraint of this utility model.
