Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an attachment/detachment device for attaching/detaching power transmission equipment such as a transmission from a vehicle body.

BACKGROUND TECHNOLOGY Conventionally, a power transmission device a such as a transmission that transmits the power of an engine mounted on a vehicle to drive wheels, etc. is attached to a vehicle body c using fasteners b such as bolts, as shown in Fig. 5. An engine (not shown) mounted on the side of the vehicle body c and a power transmission device a are connected by a universal joint d.

Problems to be Solved by the Invention When such a power transmission device a is to be removed from the vehicle body c, for example, for repair, etc., first disassemble the universal joint d and separate the two, then loosen the fixing device b and remove the universal joint from the vehicle body c. There was a problem in that it was necessary to remove the power transmission device a from the vehicle body c, which required a lot of time and effort.

This invention was made for the purpose of improving the above-mentioned problems.

Means and action for solving the problem A joint is provided between the output shaft of an engine mounted on the vehicle body and the input shaft of a power transmission device that is detachable from the vehicle body. Spline engagement with a sleeve that can move freely in the axial direction,
Further, by making the sleeve movable by an operating lever, the coupling can be freely engaged and detached, and is fixed to a guide member protruding from the power transmission device side below the coupling and to the vehicle body 1 side, A device for attaching and detaching a power transmission device is provided with a bracket having a concave step with which the tip of the guide member engages, so that the attachment and detachment of the power transmission device can be performed by operating an operating lever.

Embodiment An embodiment of this invention will be described in detail with reference to the drawings. In the figure, 1 is a vehicle body, 2 is an output shaft of an engine mounted on the vehicle body 1, and one end of the joint 3 is connected to one end 3 ₁ are spline engaged. Above joint 3
Flanges 3a are provided at opposing ends thereof, splines 3b are formed on the outer peripheral surfaces of these flanges 3a, and the inner peripheral surface of the sleeve 4 is spline-engaged with these splines 3b.

A flange 5 is fixed to the engine side end of the sleeve 4, and the sleeve 4 is locked to the flange 3a of one joint ₃₁ , and the other end of the sleeve 4 is connected to the other joint ₃₂ . flange 3
b is adapted to abut against a flange 15 fixed to b.

On the other hand, the above joint 3 ₂ is a power transmission device (not shown)
is spline-engaged with the input shaft 6 of the
A semi-cylindrical guide member 7, one end of which is fixed to a power transmission device, is provided below the joint 3. The other end of the guide member 7 is connected to a recessed step 8a of a semi-cylindrical bracket 8 fixed to the vehicle body 1.
fitted inside.

Further, an annular groove 4a is formed in the outer circumferential surface of the sleeve 4, and a small diameter portion 10a of a pin 10 protruding from one end of a substantially V-shaped lever 9 is engaged with this annular groove 4a. Large diameter part 1 of pin 10
0b is engaged with the upper edge of the guide member 7 fitted into the recessed step 8a of the bracket 8, and is engaged with the upper edge of the guide member 7.
is locked so that it does not come off upwards. Above lever 9
The bent portion is rotatably supported on the bracket 8 by a pivot 11, and one end of a connecting rod 12 is pivotally attached to the other end of the lever 9. The other end of the connecting rod 12 is a lever 1 whose one end side is pivotally supported on the vehicle body 1.
The lever 1 is pivoted near the pivot side of the lever 1.
The other end of 3 is connected to an operating lever (not shown) via a connecting rod 14.

Effects of the invention Since this invention has been described in detail above, when removing a power transmission device such as a transmission from the vehicle body 1, when the operating lever is pushed down and the lever 9 is rotated clockwise, the pivot 11 is rotated. The pin 10 rotates around the center, and the sleeve 4 is moved toward the output shaft 2 side, and the sleeve 4 is removed from the joint 3 ₂ on the input shaft 6 side, and the pin 1
Since the large diameter portion 10b of 0 is removed from the upper edge of the guide member 7, the power transmission device can be easily removed upward.

In addition, when the maintenance is completed and it is to be mounted on a vehicle, the end of the guide member 7 is fitted into the recessed part 8a of the bracket 8 so that the joint 3 ₂ faces the joint 3 ₁ on the output shaft 2 side. Simply pull up the operating lever and move the sleeve 4 toward the input shaft 6 side, and each joint 3 ₁ , 3 ₂
This makes it possible to connect and remove power transmission equipment in a short time and efficiently without requiring any skill.
