Problems solved by technology

[0004] In the above locking device design, the pin engaging the spool is a part of the solenoid, which is directly electromagnetically driven by the solenoid, and directly bears the engaging force of the spool when locking the parking mechanism, which makes the solenoid Structural components are stressed
At the same time, because in the locked state, the solenoid needs to be continuously energized to keep the pin engaged, so it is easy to cause an excessive load burden on the solenoid device, thereby shortening the life of the solenoid drive mechanism

Embodiment Construction

[0018] Specific implementations of the locking device according to the present invention will be described below with reference to the accompanying drawings. The following detailed description and drawings are used to illustrate the principles of the present invention. The present invention is not limited to the described preferred embodiments, and the protection scope of the present invention is defined by the claims.

[0019] According to an embodiment of the present invention, a locking device for a transmission is provided, which can lock a parking mechanism in the transmission at a parking position or a release position. refer to figure 1 with figure 2 , which shows a cross-sectional view of the locking device according to the present embodiment. As shown in the figure, the locking device includes a housing 1 and a piston 2. A substantially cylindrical cavity is formed in the housing 1, and the piston 2 is also cylindrical, and the piston 2 is installed in the cavity. ...

Abstract

The invention relates to a locking device. The locking device is used for locking a parking mechanism at a parking or releasing position. The locking device comprises a shell and a piston for pushingthe parking mechanism, the piston is slidably mounted in a cavity of the shell, and the locking device further comprises a locking rod rotatably mounted in the shell and a reset mechanism for applyingelastic force to the locking rod. When the locking rod is not subjected to driving force, the elastic force of a reset mechanism can enable the locking rod to be kept at a first position connected with the piston, so that the position of the piston in the cavity is locked; and when the locking rod is subjected to driving force, the locking rod can overcome the elastic force of the reset mechanismto rotate relative to the shell to a second position separated from the piston, so that the piston can slide in the cavity. The locking device is compact in structure, and the service life of a driving mechanism can be prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicles. In particular, the invention relates to a locking device for locking a parking mechanism in a parked or released position. Background technique [0002] The parking mechanism is an important component in the gearbox. The parking mechanism is usually realized by using the parking pawl. When the parking brake is required, the parking pawl is driven to engage the drive shaft of the transmission, so that the drive shaft remains stationary; when the vehicle needs to be started, the drive park pawl is disengaged. drive shaft so that the drive shaft can drive. In order for the parking mechanism to be held in the engaged position in the park state or the released position in the drive state, a locking device capable of locking the push rod of the parking pawl in position is also required. [0003] For example, CN 109307070 A discloses a transmission parking control system with a current typical locki...
