Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission support device, and more particularly to a device for attaching an extension housing to a vehicle body member.

BACKGROUND OF THE INVENTION Conventional transmission extension housings are fixedly connected to vehicle body parts by means of bolts and nuts screwed onto the bolts. However, when a large external force is applied to the vehicle body, a large inertial force acts on the extension housing having a large mass, causing relative displacement between the extension housing and the vehicle body member. If this displacement is large, the weakest and most expensive extension housing may be damaged, for example, cracked.

Summary of the invention This invention avoids the drawbacks of the conventional method by allowing the extension housing to be displaced relative to vehicle body members without being damaged when a large external force is applied in the axial direction of the extension housing. It is.

That is, the present invention provides a transmission support in which a support bracket supporting an extension housing of a transmission is coupled to a vehicle body member by a bolt passing through the support bracket and the vehicle body member, and a nut screwed to the bolt. In the device, a long groove is formed in the support bracket in the axial direction of the extension housing, and the sliding member disposed in the long groove is attached to the support bracket portions on both sides of the long groove with shear pins, and the support bracket is The bracket is connected to the vehicle body member by means of the bolts and nuts through the sliding member.

Conventional Example In FIGS. 1 and 2, reference numeral 1 designates an extension housing that is flanged to the rear of a transmission case 2, and is fastened to a rear mount 4 via bolts 3. The rear mount 4 is supported by a support bracket 5 extending in the axial direction of the extension housing 1, and this support bracket 5 has a bolt 7, which passes through the support bracket 5 and the vehicle body member 6, at both ends, and a bolt 7 that is screwed into the support bracket 5. They are each tightened and connected to the vehicle body member 6 by nuts 8 provided therein.

Embodiment In contrast, according to the present invention, FIGS.
As shown in the figure, the support bracket 5 has a long groove 1 extending in the axial direction of the extension housing 1.
0, and a sliding member 13 having a slit-like recess 12 in the long groove 10 that engages with the longitudinal edge 11 of the long groove 10.
is located. This sliding member 13 is connected to the support bracket 5 via a shear pin 14 which shears with a specific shear force. The vehicle body member 6 and the sliding member 13 are coupled to each other by a bolt 7 and a nut 8 passing through them.

Function and Effect Now, when a large external force is applied to the extension housing 1 in the axial direction, this force is applied to the bolt 3,
Rear mount 4, support bracket 5, bolt 7,
It is transmitted to the vehicle body member 6 via the sliding member 13 and the shear pin 14. However, if this force exceeds a specific value, the shear pin 14 is sheared and the extension housing 1 can be displaced relative to the vehicle body member 6, thereby preventing damage to the extension housing 1. Moreover, sea pin 14
Since energy is consumed due to the shearing of
There is also the advantage that the acting force is alleviated.
