The sealing plug 18 at the right end of the second oil passage 7 can be used for adjusting the pressure in the second oil passage 7 and the third oil passage 8 and adjusting the movement of the push rod 11.
When the vehicle unlocking device works, a system runs, because the sealing plug 18 is arranged at the right end of the second oil duct 7, hydraulic pressure/air pressure provided by the gearbox can sequentially pass through the first oil duct 4, the annular oil duct 14, the fourth oil duct 15, the second oil duct 7 and the third oil duct 8, finally acts on the push rod 11, the push rod 11 is ejected out of the first through hole 9, the push rod 11 pushes the unlocking execution block 21 to move along the direction departing from the tooth shaft 3, because the unlocking execution block 21 is connected with the locking execution block 22 through a bolt, the locking execution block 22 is separated from the locking part 5 in the moving process along with the unlocking execution block 21, and the vehicle enters an unlocking state. After the vehicle is unlocked, the gear can drive the gear shaft 3 to rotate, the unlocking execution block 21 and the locking execution block 22 also rotate along with the gear shaft 3, and in the rotating process, after rotating at a certain angular speed, the unlocking execution block 21 and the locking execution block 22 are influenced by centrifugal force, so that the unlocking execution block 21 and the locking execution block 22 are self-adaptive, and can rotate without hydraulic pressure ejection. When the system stops, the second cavity 13 in the locking execution block 22 causes the weight to be smaller than that of the unlocking execution block 21, under the action of inertia, the unlocking execution block 21 and the locking execution block 22 can continue to rotate for a certain angle, or a slope slipping phenomenon can occur when the locking execution block 22 goes up/down a slope, when the locking execution block 22 rotates to the upper side of the locking component 5 along with the gear shaft 3, the unlocking execution block 21 and the locking execution block 22 can sink, the locking execution block 22 is locked in the locking component 5, the gear shaft 3 stops rotating, and then the gear is stopped to run, so that the vehicle locking and parking are completed. The whole working process does not need to be executed depending on the operation of the driver. The shafting locking device 5 has few components and simple structure, and greatly reduces the installation space.
The invention further provides the automobile, and the shafting locking device is arranged in the shell of the automobile. The specific structure of the shafting locking device refers to the above embodiments, and since the automobile adopts all the technical solutions of all the above embodiments, all the beneficial effects brought by the technical solutions of the above embodiments are at least achieved, and are not repeated here.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
