Abstract

PURPOSE:To firmly hold a vehicle in a stopping condition on a slope, by disposing an one-way clutch between the input shaft of a speed change gear and the stationary side so that the clutch is locked in association with the reverse rotation of the input shaft. CONSTITUTION:First to fourth drive gears 18 through 21 are integrally incorporated with an input shaft 9 which is coupled to a clutch 1, and an output shaft 22 is laid in parallel with the input shaft 9. Further, an output shaft 30 which is arranged at one end part of the output shaft 22, is meshed with a ring gear 32 in a differential gear until 31 in a final speed reduction unit 3. Therefore, the power from the output shaft 22 is transmitted to a side gear 36, and is then transmitted to drive wheels through an axle 37. Further, an one-way clutch 41 disposed between the rear end part of the input shaft 9 and a stationary side casing 40 effects a locking operation to inhibit the drive system after the input shaft 9 from reversely rotating, and therefore, the vehicle is held in its stopping condition without moving backward.

In the case of a temporary stop on an uphill slope, the clutch is disengaged by depressing the clutch pedal, or the gear is set to the 2J-tral position, and braking is performed by depressing the foot brake Jj or operating the parking brake. Therefore, when starting from such a state, it is necessary to increase the engine output by pressing the accelerator pedal while also releasing the clutch pedal and brake operation, which is extremely complicated. One thing has been pointed out. For this reason, conventionally, for example, as shown in Japanese Patent Publication No. 4G-2860G, when stopping 71i, the hydraulic braking device, which is often used, is always used to stop both sides in the l-state. A hill holder device has been proposed. However, in this type of device that uses a hydraulic lubrication device, a means to prevent the return of the hydraulic pressure and a first stage that is released when starting is required in the hydraulic system, and the number of grooves is reduced. There is a problem. There is a problem with the problem of wooiming when releasing before starting. [Object of the Invention] The present invention is directed to the above-mentioned prior art hydraulic oil hydraulic system. In view of the problems when driving a vehicle that rotates in reverse when backing up, we designed a simple 1-11 configuration with J3 in the drive system of a vehicle that rotates in reverse when backing up. It is an object of the present invention to provide a corrosion prevention device 7I of the present invention. Focusing on the fact that the shaft rotates in the forward direction even when power is transmitted from the engine or when moving in reverse, it rotates in the reverse direction when the vehicle reaches ff2 f with gear 1 shifted to forward gear. A one-way clutch is installed between the shaft and the fixed side so that it locks when reversed, and if the clutch is disengaged with the gear set to OFJ gear when stopping temporarily on a slope, the vehicle will try to move backwards. The gist of this invention is that the one-way clutch acts as a lock to maintain the vehicle in a stopped state. [Embodiment] Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. In Fig. 1, I will explain in detail how an electromagnetic powder clutch is assembled into a transaxle type transmission.Regular code 1 is an electromagnetic powder clutch, 2 is a 4-speed forward/reverse transmission,
3 is a final reduction gear. ? I:im The powder type clutch 1 connects a drive plate 6 to a crankshaft 5 from the engine within a clutch case with a sealed structure.
A drive member 8 having a built-in coil 7 is integrally connected through the input shaft 9 of the transmission 2, and a driven member 10 is spline-fitted to the input shaft 9 of the transmission 2 so as to be integrated in the rotational direction.
It is closely fitted to the drive member 8 through the plug 11, and the electromagnetic powder is supplied from the powder chamber 12 to the socket 11.
It is designed to give +1. Further, a shaft 13 is integrally connected to the drive member 8, and its cylindrical end is loosely fitted to the input shaft 9, and a slip ring 14 is attached thereto, and this slip ring 14 and the drive member 8 A lead wire is connected between the slip ring 14 and the slip ring 14, and a brush 1G in contact with the lead wire is held by a holder 17 and is in sliding contact with the coil 7 for power supply. With this configuration, the drive plate 6 and the drive member 8 rotate together with the crankshaft 5, and the electromagnetic powder contained in the powder chamber 12 is appropriately moved toward the inner peripheral surface of the drive member 8 by centrifugal force. It is being Therefore, when power is supplied from the lead wire to the coil 7 via the brush 16, slip ring 14, and lead wire, the excitation of the drive member 8 creates lines of magnetic force around the driven member 10. Electromagnetic powder accumulates in the drive member 8 and the driven member 10 so that the engine power of the crankshaft 5 is transmitted to the input shaft 9. Next, the C transmission 2 has an input shaft 9 connected to the clutch 1.
First to fourth speed drive gears 1B to 21 are integrally provided to the input shaft 9, and an output shaft 22 is disposed parallel to the input shaft 9 and constantly meshes with each of the gears 18 to 21. The driven gears 23 to 2G are rotatably fitted, and the two adjacent driven gears 23 and 24 are connected to the output shaft 22 by the synchronization mechanism 21, and the driven gear %i25
and 26 are connected to the output shaft 22 by another mechanism 28, and a reverse gear R1829 is provided between these and the output shaft 9.22. In this way, by operating the change lever and integrally coupling the driven gear 23 to the output shaft 22 by the synchronization mechanism 27, the power of the input shaft 9 is decelerated most by the gears 18 and 23, and is taken out to the output shaft 22 to reach the first speed. is obtained, and 8-speed shifting is performed in the same manner. Further, an output gear 30 is provided at the end of the output shaft 22 and meshes with a ring gear 32 in a differential device 31 of the final reduction gear 3, thereby causing the output shaft 22 of the transmission 2 to generate power. is immediately transmitted from the ring gear 32 to the side gear 3G via the case 33, spider 34, and binion 35, and further transmitted to the drive wheels via the axle 37. Therefore, in the transmission 2, a one-way clutch 41 is installed between the rear end of the input @9 and the fixed side case 40. This one-way Clara F41 is shown in FIG. A roller 45 is housed in between. When the input shaft 9 rotates in the normal direction as shown by the solid line, the l''-ra 45 is retracted to the full 44 person i\ side to make it free, and when attempting to reverse, [the cola 45 is pushed into the small diameter side of the full 44 person. [1] Next, the operation of Km configured in this way will be explained. First, when the vehicle moves forward using engine power, the electromagnetic clutch 1 is integrally engaged and the engine power is transmitted to the input shaft 9 of the transmission 2. In addition, in the transmission 2, the driven gear 23 is
Any one of 26 to 26 is integrally coupled to the output shaft 22,
As a result, the output shaft 22 becomes 311 with respect to the input) shaft 9 due to the gear meshing! ! ! + to output shifting power, which is transmitted to the wheels.In this case, the rotation direction of each part is as shown by the solid line in Fig. 2. Therefore, if the width speed decreases just before stopping while driving on an uphill slope under such conditions, the purpose of preventing
It now releases like an icta type clutch,
This allows the transmission 2 to remain shifted to the forward gear. Here, in consideration of a later start on a slope, it is desirable to shift to a low gear such as first gear. In this way, the vehicle is stopped by brake operation with the electromagnetic clutch 1 released, but when the brake pedal is released immediately thereafter, the ring gear 32 of the transmission 2, the output gear 30. The output shaft 22 and the input shaft 9 connected thereto try to reverse and move backward as shown by the broken line in FIG. Then, the one-way clutch 41 attached to the input shaft 9 engages in a locking action, thereby preventing the drive system after the input shaft 9 from reversing, thus preventing the vehicle from moving backward.
(The vehicle is held in a stopped state.) Next, when starting on an uphill slope, the electromagnetic clutch 1 automatically engages when the accelerator pedal is depressed to reverse one engine rotation. Then, the engine power is transmitted to the input shaft 9, causing the vehicle to rotate forward again.Therefore, one clutch of the one-way clutch 41 is automatically released, and the power for changing gears is output from the output shaft 22 onwards, and the vehicle starts. In addition, it is possible to perform the locking action by the one-uni-kurage 41 even in the S-position of stopping on a downhill slope with the reverse gear shifted. Although we have described the above case, it can be similarly applied to the case with a normal R!J friction type clutch.However, ■γ1-stroke type clutch requires operation of the clutch pedal. [Effects of the Invention] The above-mentioned effects As is clear from the description, the backward rolling prevention device of the present invention uses the power transmission state in the vehicle's drive system to automatically lock or release the one-way clutch, so the structure is extremely simple. The timing of release is also good.It is preferable because it eliminates the burden on the hydraulic system as in the case of hydraulic braking type, and since it is mechanically locked by a one-way clutch, it is possible to firmly maintain the vehicle stop on a slope.Especially as in the embodiment If the device is equipped with an electromagnetic clutch that automatically connects and disconnects, the operation becomes easy and the effects of the present invention can be fully exhibited.
