DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting transmissions having different lengths on a truck or the like.

[0002]

2. Description of the Related Art In a truck or the like, as shown in FIG. 4, an engine 1 and a transmission 2 are integrally connected, and both sides of the engine 1 are respectively connected to left and right side rails 4 via an engine mount 3. The transmission 2 is supported by a cross member 5 straddling the left and right side rails 4 via a support bracket 6, and is mounted on the vehicle body side. Is changed from the cross member 5 to the transmission 2 due to a difference in the length of the transmission 2 or the like.
In some cases, the position at which the cross member 5 is attached to the side rail 4 must be displaced by the same dimension. The mounting structure of the member 5 had to be changed, and an increase in production cost could not be avoided.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily move a support position of a transmission mounted on a vehicle in the front-rear direction of the vehicle with a simple structure.

For this reason, a transmission mounting apparatus according to the present invention is characterized in that a cross member having both ends fixed to left and right side rails extending in the front-rear direction of the vehicle and arranged in the vehicle width direction is separate from the cross member. A transmission bracket which is formed on the cross member at intervals in the vehicle width direction so as to be reversible in the vehicle front-rear direction, and at a position offset in the vehicle front-rear direction from the vehicle front-rear mounting center of the transmission bracket, respectively. A support bracket connected to the transmission bracket and connected to the transmission casing is provided.

[0005]

Accordingly, by replacing each transmission bracket in the front-rear direction of the vehicle in the opposite direction, and replacing the left and right transmission brackets in the same arrangement and attaching them to the cross member,
The connection position of the support bracket to the transmission bracket can be moved in the front-rear direction of the vehicle by a distance twice as long as the above-mentioned one-side without changing the fixing position of the cross member to the side rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be specifically described below. Both ends of a cross member 5 having a hat-shaped cross section extending in the vehicle width direction are bolted to left and right side rails 4 extending in the front-rear direction of the truck, and a transmission bracket 7 having a substantially hat-shaped cross section has two flange portions 8. 3 is opposed to both flange portions 9 of the cross member 5 as is often seen in FIG. 3, and is fixed symmetrically to the left and right sides of the cross member 5 by fixing the bolts 10 and 10 at intervals in the longitudinal direction of the vehicle. A lower portion of a rubber mount 12 is bolted to a bottom portion 11 which is attached and inclined to the outside of each transmission bracket 7.

A support bracket 6 extending below the cross member 5 in the vehicle width direction is provided above each rubber mount 12.
The left and right inclined portions 13 are fixed by stud bolts 14 of a rubber mount 12, and the top and rear surfaces thereof are welded to the support bracket 6 and are suspended therefrom.
6 is bolted, and the transmission 2 is suspended from the cross member 5 via the rubber mount 12.

In this case, as shown in FIG. 3, the position of the stud bolt 14 for fixing the inclined portion 13 of the support bracket 6 on the upper part of the rubber mount 12 is determined before and after the transmission bracket 7 is mounted on the cross member 5. The bolts 10 and 10 are configured so as to be offset rearward from the intermediate position A by a distance a.

On the other hand, the left and right transmission brackets 7 arranged as shown in FIG. 3 are replaced with their front and rear sides (left and right in FIG. 3) as shown by two-dot chain lines in FIG. In this state, replace the left and right transmission brackets 7
If the stud bolts 14 on the rubber mount 12 are attached to the cross member 5 by 0 and 10, the positions of the stud bolts 14 move forward (leftward in FIG. 3) by a distance of 2a from the illustrated state.

[0010] That is, the stud bolt 14
If the inclined portion 13 of the support bracket is fixed, the bolting position of the phosphorus hose 15 with respect to the transmission casing moves by the distance 2a, so that the mounting position of the cross member 5 to the side rail 4 is not changed at all, and Thus, the transmission whose suspension position from the cross member 5 is shorter by 2a can be directly supported without changing the structure of the support bracket 6 and the transmission bracket 7. Therefore, even when a transmission or the like having a different length is mounted, the mounting structure of the cross member 5 of the side rail 4 can be made constant and shared, so that the production cost can be easily reduced.

[0011]

According to the transmission mounting apparatus of the present invention, the transmission mounted on the cross member is detachably mounted.
Fixing cross members to side rails by changing the arrangement of transmission brackets
The position of the support bracket supporting the transmission can be moved by a predetermined distance in the front-rear direction of the vehicle without changing the position , so that even when transmissions having different lengths are mounted, the side rail and the cross member can be moved. Since specification changes can be reduced and shared, the side rails and cross
The production cost of Nba can be easily reduced.
