Abstract

PURPOSE:To precisely obtain gear mesh, neutral stop and parking brake operated conditions, by providing a piston member slidable by supply of pressure to oil chambers between a shift gear adapted to engage with and disengage from a drive gear and a support shaft for the shift gear, and supplying pressure to the oil chambers. CONSTITUTION:In a vehicle such as an agricultural combine having tracks, shift gears 27 adapted to engage with and disengage from a drive gear 21 for selecting power transmission to a lower gear 28 are slidably engaged with the outer periphery of a support shaft 22. Slidable piston members 24 are provided between the shifts gears 27 and the support shaft 22. Oil chambers 25 and 26 are defined between opposite ends of the slidable piston members 24 and the support shaft 22. By supplying pressure to the oil chambers 25 and 26, three positions of gear mesh condition between the shift gears 27 and the drive gear 21, neutral stop condition and parking brake 29 operated condition are precisely maintained. Thus, the power transmission to each track is carried out at the three positions to achieve gentle turn as well as rapid turn with a simple construction.

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a support shaft for a shift gear that meshes with and separates from a drive gear and performs on/off operations for transmitting power from the drive gear to a lower traveling device. The present invention relates to a side clutch brake operation structure which is slidably fitted onto the outside of the clutch and which is configured so that after the shift gear is separated from the drive gear, the shift gear presses and brakes the side brake.

The above-mentioned side clutch brake operation structure is provided for each of the left and right traveling devices, and the power generated by the gear shift operation in the transmission is branched into two systems, and the branched power is transmitted to the two sets of side clutch brakes. The configuration is such that the information is transmitted to the left and right traveling devices via the vehicle. When turning, the shift gear cuts off power transmission to one side of the traveling device, and the handbrake is used to perform a braking operation, thereby making it possible to make a small turn.

However, depending on the work situation, there may be cases where a gentle turn is performed by simply cutting off the power transmission to one traveling device without pressing the handbrake. In this case, it is necessary to separate the shift gear from the drive gear and hold it in a so-called neutral stop position before pressing the handbrake. An example of this structure is disclosed in Japanese Utility Model Application Publication No. 59-56175. .

In the disclosed structure, an oil drain passage having a variable throttle part is provided in the middle of a hydraulic cylinder that operates a shift gear, and pressurized oil is supplied to the hydraulic cylinder to drain the oil from the vicinity where the shift gear is completely separated from the drive gear. The oil passage and the oil chamber of the hydraulic cylinder are communicated with each other to reduce the extension speed of the hydraulic cylinder or to stop the extension so that the handbrake is slowly operated or the shift gear is held at the neutral stop position. It is structured like this.

As mentioned above, if the structure is such that the operation of the hydraulic cylinder that operates the shift gear is stopped by the oil drain action from the oil drain path and the shift gear is held at the neutral stop position, the pressure oil from the pump to the hydraulic cylinder is stopped. Unless the amount of oil supplied and the amount of oil discharged from the oil drain path are approximately equally balanced, the shift gear cannot be accurately held at the neutral stop position, and this holding state can be said to be unstable.

A feature of the present invention is that in the above-mentioned side clutch brake operation structure, a piston member that is slidably operated by a certain stroke by supplying pressure oil to a first oil chamber formed on the outer periphery of the support shaft is connected to the shift gear and the support shaft. a second oil chamber is formed between the piston member and the shift gear, and the shift gear can be operated to separate from the drive gear via the piston member by supplying pressure oil to the first oil chamber; Further, the handbrake is configured to be press-braking operated by a shift gear by supplying pressurized oil to both the first and second oil chambers, and its functions and effects are as follows.

Then, when pressure oil is supplied only to the first oil chamber, the piston member moves the shift gear by a set stroke, thereby separating the shift gear from the drive gear. In other words, by maintaining the pressure oil supply state to the first oil chamber, the piston member and the shift gear are separated from the drive gear and maintained in a neutral stopped state in which the handbrake is not operated.
