Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission device mainly applied to a four-wheel drive vehicle.

Conventionally, this type of device is known to have a multi-speed transmission installed on the side of the engine block, which has a number of shiftable gears. There is a need to add over-top functionality and/or even emergent-low functionality.

The present invention is a device that can satisfactorily meet these various demands, in other words, even if the above-mentioned functions are added or deleted, the basic part thereof, that is, the above-mentioned multi-stage transmission part, can be improved. In this diversification, there are no changes, and in this diversification the common parts: increase, and the purpose is to carry devices that improve mass productivity and reduce costs. In a type equipped with a multi-stage transmission, a first transmission consisting of the multi-stage transmission, a second transmission for direct connection or overtop, and a third transmission for Emerging Engine are combined into one transmission. It is characterized by being arranged sequentially on the side of the engine block.

The purpose of the second invention is to obtain a device that ensures the shaft support of each transmission and eliminates the need for a separate shaft support by adding or deleting such functions. A first gearbox consisting of a multi-stage transmission having a plurality of gears, a second gearbox for a direct connection or an overtop gearbox, and a third gearbox for an emergent engine are sequentially arranged on the side. , each transmission is housed separately in each case.

An example of implementing the present invention will be explained with reference to the attached drawings.

In the drawing, (1) shows an engine block mounted on a four-wheeled vehicle, and (2) shows a multi-stage transmission on the side of the engine block. (3
) is connected to the input shaft (5) and 1 via the speed change clutch (4).
There are 4 forward gears and 1 reverse gear between the output shaft (6) parallel to this.
A case (7) which is selectively provided with a transmission system Gl*Gl+G3+G4+GR with the stage and accommodates it on its outer periphery.
, and both shafts t5) [61] were pivotally supported on this.

The output shaft (6) is provided with an outer drive shaft (9) connected to it via a gear train (8), and the drive shaft (9)
The rear wheel drive shaft (9a) extending rearward and the front wheel drive shaft (9b) extending forward can be directly coupled via an intermediate clutch (9C), and thus the clutch (9C)
By opening and closing the VC, a state where only the shaft (9a) for driving the rear wheels is driven and a state where both shafts (9a) (9b) are driven together can be obtained.

According to the present invention, the multi-stage transmission (2) is used as a first transmission, and a second transmission 0υ of direct connection or overtop capability is added to the multi-stage transmission (2) so that these can be removed. 1st
transmission (2), the nuclear second transmission 0.0), and the third transmission a
υ are sequentially arranged on the side of the engine block tlJ.

To further explain, in the illustrated example, the second transmission QOI
is a human power shaft α formed by extending the input shaft (5) described above to the other side.
2 and 1. A transmission consisting of a direct-coupled or over-top type gear (14) (141) that can be operated refractively is connected between the output shaft α3) formed by laterally extending the output shaft (6) described above. System G
A case (151) is provided on the outer periphery of the case (151), and both shafts (12 (131) are pivotally supported), and the third transmission Ql further extends the input shaft (5). a transmission system consisting of an input shaft ae, an output shaft formed by further extending the output shaft (6) via a spline joint (17), and an emergent engine gear alaa operated refractively therebetween. Gel, and a case (
2f) on which the shaft (18) is supported.

The above-mentioned spline joint αη has eight gears (1
In 7Q, the outer gear (17b) is engaged with the VC to create a drive system for a speedometer (not shown), and the case (151 is connected to the left and right hand parts (15a) and (15b) in the drawing). It is divided into the right half (
The half part (1s
b) is removed as necessary so that the case (15+) can be made into a φ shape, and furthermore, inside the half part (15b) is a pair of shafts that pivotally support the extensions of the above-mentioned two shafts +5) 161. Support members (15o) and (15c) are provided. In addition, one of the pair of gears described above, that is, the gear 0 on the input side, is made on the input shaft (161 itself) in the case shown, but this is made of the input shaft (5) described above and its extension. When considering this, since it is formed at the outermost end, its rigidity is not impaired.

To explain its operation, the device of the present invention is manufactured, for example, as shown in the first diagram, and in this case, it is equipped with a multi-stage transmission (1υ) as the first transmission (2), and has a direct connection or overtop function as a whole. However, if necessary, for example, if the emergent engine low function is not required, the outermost sixth transmission (old) can be removed and the overtop function can be added. If it is not necessary, it is sufficient to remove the second transmission (It) inside it. To explain this further, the second transmission gear and the sixth transmission gear 11D are made by longitudinally extending the input shaft (5) and output shaft (6) that go into the first transmission (2). If the third transmission σB is not required, the corresponding extension can be reduced to obtain, for example, the state shown in the second diagram.

In this case, the outer periphery of the case (20) may be left as is, or it may be made more or less flattened as shown in FIG.

Furthermore, the second transmission [(2) is almost the same if it is not required,
For example, by reducing the shaft (+21 (131), which is the corresponding extension part, the state shown in FIG. There is only a half part (15a), and the above-mentioned case (2()) is attached to the open end of the half part (15a) as it is or after being flattened.

In this way, according to the present invention, a second transmission for direct connection or overtop is provided on the side of the first transmission which is a multi-stage transmission;
Further, a third transmission for the Emerging Engine and Low is sequentially arranged on the side thereof, and when the third transmission is removed while leaving the second transmission, which is more or less necessary, the second transmission. There is no need to make any changes to the first transmission and the first transmission, and furthermore, if the second transmission is removed, there is no need to make any changes to the first transmission, thus reducing the need for common parts for diversification of functions. In addition, since the third transmission is located on the outermost side, the input gear of the third transmission is made on the input shaft itself, but it is not the same as the input of the first transmission. Being the outermost end of the extended portion of the shaft, the input shaft and the extended portion have the effect that there is no decrease in rigidity as a whole. Furthermore, according to the second invention, each reduction gear is separately housed in each case and is pivotally supported by each case, and the sixth transmission or further the second transmission is removed or added. This also eliminates the need for a separate shaft support and has the advantage of simplifying the configuration.
