Description

Technical Field

[0001] The utility model belongs to the technical field of drivers and relates to a driver ratchet. Background Art

[0002] The pawl is a part that drives the ratchet to make intermittent motion. The pawl is driven by the connecting rod to make reciprocating motion, thereby driving the ratchet to make unidirectional motion, which is used to clamp the ratchet and make the ratchet move unidirectionally. It is a structural part that is locked in the reverse direction. In the existing parking system, the pawl is controlled by the shift actuator or the shift cable, and is rotated around the pawl rotating shaft under the action of the actuator and meshes with the parking ratchet to lock the output shaft or the differential, thereby achieving the purpose of parking. In the prior art, the parking pawl of the pawl is usually arranged in the front, and the driving boss of the pawl is arranged on the back of the pawl, so that the actuator of the parking system can be arranged on the same layer as the pawl, shortening the axial dimension of the parking system to reduce the axial dimension of the transmission.

[0003] The existing pawls have fixed connection structures at both ends, and the connection ends and the pawls are integrally formed. With such a structural setting, when the installation site is wide and the connection end is not long enough, it is difficult to stably install the connection end, and improvement is needed. Summary of the invention

[0004] The purpose of the utility model is to provide a driver pawl to solve the problems raised in the above background technology.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a driver pawl, comprising a pawl body, a mounting head 1, a mounting head 2, an adjusting knob, a mounting seat and a driving rod body, the mounting head 1 and the mounting head 2 are respectively arranged on both sides of the pawl body, the mounting head 1 is movably arranged, an inner support column is arranged between the mounting head 1 and the pawl body, one end of the inner support column is fixedly connected to the pawl body, the other end of the inner support column is fixedly connected to an inner push frame, and the inner push frame slides inside the mounting seat.

[0006] In the above-mentioned drive pawl, guide slides are provided at the top and bottom of the inner support column, and the guide slides slide inside the guide groove opened on the inner wall surface of the mounting seat, and a plurality of positioning holes arranged side by side are opened inside the guide slide.

[0007] In the above-mentioned drive pawl, side grooves are provided on both sides of the mounting seat, and positioning screws are installed inside the side grooves. One end of the positioning screw passes through the mounting seat and is threadedly connected to the inside of the positioning hole. Once the mounting head slides to the mounting position, the positioning screws on both sides of the mounting seat can be rotated, and the positioning screws are threadedly connected to the inside of the positioning hole to further complete the positioning of the mounting seat.

[0008] In the above-mentioned driver pawl, the internal threaded sleeve of the inner push frame is provided with a screw, one end of which is fixedly connected to a bevel gear 2. The screw, bevel gear 1 and bevel gear 2 of the present application are all standard parts.

[0009] In the above-mentioned driver pawl, the side surface of the bevel gear two is meshedly connected with the bevel gear one, one end of the bevel gear one is fixedly connected with a driving rod body, one end of the driving rod body passes through the mounting seat and is fixedly connected with the adjusting knob on the outside of the mounting seat. When adjusting, the adjusting knob on the side of the mounting seat is rotated to drive the bevel gear one to rotate through the driving rod body, and the bevel gear one and the bevel gear two are meshed, thereby mobilizing the screw to rotate. When the screw rotates, the inner push frame connected to the screw will push the inner support column toward the outside.

[0010] Compared with the prior art, the advantage of the driver pawl of the utility model is that an inner support column and a mounting seat are provided between the mounting head 1 and the pawl body. When the position of the mounting head 1 needs to be adjusted, the adjustment knob on the side of the mounting seat can be rotated to drive the bevel gear 1 to rotate through the driving rod body, and the bevel gear 1 and the bevel gear 2 are meshed, thereby mobilizing the screw to rotate, and the inner push frame connected to the screw sleeve will push the inner support column toward the outside, so that the inner support column slides out of the mounting seat, so that the mounting seat is extended. In this way, the mounting head 1 located at the end of the mounting seat can be effectively extended, and the pawl body can be conveniently installed through the mounting head 1.
