Description

Jig device for inspection of parking sprags for CVT}

The present invention relates to a jig device for inspecting parking sprags applied to a CVT (Continuously Variable Transmission) of a vehicle.

Specifically, when inspecting the shape deformation caused by heat treatment of high carbon carburization of parking sprags. This relates to an inspection jig device for parking sprags for CVT that maximizes inspection efficiency by performing inspection work quickly and accurately.

Generally, in a car, the transmission plays as important a role as the engine.

Such transmissions have been developed around automatic transmissions (ATs) due to the convenience of not having to shift gears directly, but recently, they are being developed mainly around CVTs (Continuously Variable Transmissions) focusing on economic efficiency.

In the above CVT, a metal belt is connected between variable rollers that look like gears to continuously transmit power and continuously shift gears. Not only does it provide smooth driving because there is no shift shock, but it also has a simple structure, preventing breakdowns. It is small and can be set to a wide gear ratio range, so it has the advantage of good fuel efficiency and cost savings.

Meanwhile, the CVT moves back and forth between 'P' mode, which is a parking mode where the car is parked, 'R' mode, which is a reverse mode, 'N' mode, which is a neutral mode, and 'D' mode, which is a driving mode.

In the above, parking mode restricts the movement of the car when parking, reverse mode is a driving mode that transmits driving force for driving the car in reverse, neutral mode separates the engine and drive shaft, and driving mode is different from reverse mode. Conversely, it is a driving mode that transmits driving force for forward movement of the car.

This parking mode is operated by performing a series of processes of gear lever - manual shaft - parking rod - parking sprag when the gear lever is placed in P mode.

That is, as the parking rod slides and moves in conjunction with the operation of the gear lever, the parking gear and parking sprag are engaged and disengaged.

In the above, the CVT includes a parking gear (not shown) installed on the output shaft in the transmission case, a parking sprag rotatably installed on the upper side of the parking gear about a support axis, and a shift lever at the top of the parking sprag. It is configured to include a parking rod assembly installed to mesh between the parking gear and the parking sprag when located in the range.

In the above, the parking sprag is formed with a fork portion meshing with the gear teeth of the parking gear, a raising and lowering pressing portion pressed by the parking rod assembly, and a hinge hole through which the support shaft is axially coupled is formed through the parking sprag. A 'tubular' shaped hinge axis is provided to which a sprag spring, which allows the lag to return and rotate elastically, is fixed.

In the above, the parking rod assembly includes a parking rod that moves according to the operation of the shift lever, and a cam assembled to the tip of the parking rod to press the raising/lowering pressing portion of the parking sprag.

Accordingly, when the shift lever is located in the parking range, the parking rod moves, and as the parking rod moves, the cam performs a sliding operation within the rod guide supported by the rod shaft to move the parking soup. By pushing the raising/lowering pressing portion of the lag, the parking sprag is rotated downward about the hinge axis, and the fork portion of the parking sprag engages with the gear teeth of the parking gear, thereby forcibly stopping the rotation of the parking gear.

Accordingly, the necessary parking braking force is generated when parking.

In addition, when the cam pushes the parking sprag, if the groove of the parking gear and the fork portion of the parking sprag do not match, the cam compresses the load spring, and the fork portion is pressed into the groove of the parking gear. When they match, the parking sprag rotates as it moves by the restoring force of the load spring, and the cam returns due to the restoring force of the load spring.
