Description

[Detailed description of the invention] [Industrial application field] This invention relates to a support device for a parking transmission lever that is attached to a parking brake operating transmission system and connects a front cable and a rear cable. .

[Prior Art] Figure 1 shows the general configuration of a conventional parking brake operation transmission system.
Operation pull rod 1 and rear brakes 2 on both left and right sides
A front cable 3 and left and right rear cables 4 are stretched between the cables 3 and 4.
The wires are connected to each other via a transmission lever 5. The base of the transmission lever 5 is supported by the vehicle body by a pivot shaft 6, and each member of the transmission system is mounted under the floor of the vehicle body. The wire of the front cable 3 is connected to the tip of the transmission lever 5, and the wires of each rear cable are connected to the base of the transmission lever 5, so that the operating force applied to the operating pull rod 1 is increased. It acts on the rear brake 2 via the wires of each rear cable 4.

[The problem that the idea aims to solve]

By the way, in the conventional support structure for the transmission lever 5, a method was adopted in which the lever 5 was supported by inserting the pivot 6 into the shaft hole of the transmission lever 5 from above. According to (a), the vertical gap between the underfloor surface of the vehicle body and the mounting surface of the lever 5 is extremely narrow, which not only makes it difficult to attach and detach the pivot shaft 6, but also severely restricts the design of the vehicle body. b) Since the lever 5 is held simply by the pivot 6, there are problems such as insufficient support strength and lack of durability.

The present invention was made to solve the above problems, and there is no particular problem even when the vertical gap between the mounting surface of the transmission lever 5 and the underside of the vehicle body floor is narrowed, and the lever 5 is The present invention provides a parking transmission lever support device that can provide sufficient support strength.

[Means to solve the problem]

The present invention is a bracket that is fixedly installed on a vertical wall near the underfloor of a vehicle body and supports a transmission lever that connects a front cable and a rear cable of a parking brake operation transmission system. A horizontal transverse space is formed to hold the base of the transmission lever from above and below, and a bracket having a downward fork formed in its lower half, and a vertical shaft part and its lower end are integrally formed. A support shaft member consisting of a square block-shaped base formed in a square block, the shaft portion communicating with the upper and lower through holes of the transmission lever and the upper and lower through holes of the cross passage space of the bracket, and extending downwardly. The supporting shaft member is inserted from the base and has a horizontal hole in the base, and a stop pin whose middle portion is inserted into the horizontal hole and whose both end portions are supported by the fork. It is characterized by

[Effect]

The parking transmission lever of the present invention is supported by inserting a support shaft member from below into a bracket protruding from a vertical wall surface near the underfloor of the vehicle body, and the support shaft member prevents the support shaft member from falling downward. This is prevented by a locking pin inserted through the lower part of the shaft member.

〔Example〕

As shown in FIGS. 2 to 5, the support device of the embodiment includes a bracket 7 fixed to a vertical wall W near the underfloor F, and a support shaft member 8 inserted into the bracket 7 from below. , and a retaining pin 9 that passes horizontally through the lower part of the support shaft member 8 and is supported by the bracket 7.

The bracket 7 includes an upper flange 10, a pair of left and right flanges 11 at the lower part, a frame plate 12 that has a U-shaped cross section and forms a horizontal passage space, and a pair of frames that support the left and right sides of the frame plate 12. The frame plate 12 is a single member integrally formed with a fork 13, and the upper and lower plates of the frame plate 12 are provided with a hole through which the shaft portion 14 of the support shaft member 8 passes. 1
0 and 11 are welded and fixed to the vertical wall surface W. The fork 13 is provided with a hole through which the stop pin 9 is inserted.

The support shaft member 8 consists of a vertical shaft portion 14 and each block-shaped base 15 integrally formed at the lower end thereof.
is opened. A split pin 16 for preventing slippage is attached to the leg portion of the stop pin 9 whose center portion is inserted into the horizontal passage hole 15a and whose both ends are supported by forks 13.

The transmission lever 17 has upper and lower through holes formed at its base into which the shaft portion 14 of the support shaft member 8 is inserted.

However, in order to assemble the lever support device, after inserting the base of the transmission lever 17 into the transverse space in the frame plate 12, insert the shaft part 14 of the support shaft member 8 from below into the through hole of the frame plate 12 and the transmission lever. 17, and then pass the stop pin 9 through the hole of the fork 13 and the horizontal through hole 15a of the base 15, and finally, the pin 9 is prevented from coming off with a split pin 16.

[Effect of idea]

According to the present invention, in which the transmission lever is pivotally supported by inserting the support shaft member 8 from below the bracket, there is no need to provide a particular gap between the bracket 7 and the underfloor F, so that due to the design, In addition, since the transmission lever is sandwiched between the frame of the bracket and the support shaft member supporting the lever is supported by a fixing pin on the downward fork of the bracket, the support shaft member In addition to being able to be assembled from below, sufficient support strength can be obtained, which has the effect of improving the assemblability and durability of the support device.
