Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a transmission remote control device for a cab-over type automobile.

[Conventional technology]

In the case of a cab-over type automobile, the radiator R is usually located below the driver's seat S as shown in FIG. 1, or in front of the driver's seat S as shown in FIG. The radiator R is installed with a predetermined height above the ground to avoid contact with the road surface.

By the way, when constructing a transmission remote control device for a cab-over type vehicle, it is necessary to consider the relationship with the installation position of the radiator R. Conventionally, when the radiator R is located below the cockpit S, As shown in the figure, the support part b of the gear shift lever a is arranged in front of the radiator R, and the shift and select lever c provided on the support part b is installed so as to be approximately perpendicular to the cab floor d. In addition, when the radiator R is located in front of the cockpit S, as shown in the figure, the support part b of the gear shift lever a should be connected to the upper part of the radiator R, that is, as shown in the figure.
It is placed on the side of the cockpit S, and the shift and select lever c is installed substantially perpendicular to the cab floor d. Therefore, there is no problem in terms of operational functionality in either case.

[Problem that the invention attempts to solve]

However, in the former case, that is, when the radiator R is located at the bottom of the cockpit S, the gear shift lever a is long and the support point (support part b) is longer than the operating point (knob e). Because it is located in the front, it has the disadvantage of poor rigidity and maneuverability. In this respect, in the latter case,
That is, when the radiator R is located in front of the cockpit S, the shift lever a is short and the support point is approximately on the same line as the operating point, so it has excellent rigidity and operability. When applied to the former, the shift and select lever c is located on the radiator R, so the radiator R must be installed lowered to a degree that does not interfere with the movement of the shift and select lever c, and the necessary Due to the problem of insufficient ground clearance, it was impossible to apply the latter control device to the former vehicle.

By the way, as a measure to solve such a problem, as shown in FIG.
A shift and select lever c provided on the cab is installed so as to be substantially parallel to the cab floor d, and
A configuration may be considered in which the link rod f connected to these is installed so as to be approximately perpendicular to the cab floor d. In this way, the shift lever a becomes shorter, and its support point (support part b) is placed at the operating point ( Since it is located approximately on the same line as knob e), rigidity and operability are improved, and since the position (in the height direction) of radiator R is not affected by the shift and select lever c, it is possible to secure a predetermined ground clearance. can.

In addition, in the case of the above technology, the shift and select lever c is installed in a direction substantially parallel to the cab floor d, so when the shift lever a is operated in the shift direction, the operating force acts directly on the floor panel, which is not very strong. As a result, there was a risk that operational stability would deteriorate.

In the figure, g is a shift and select lever, h is a shift shaft, i is a chassis frame, and j is a steering handle.

In addition, it is shown in Utility Model Application No. 53-28372, Utility Model Application No. 142336-1980, and Utility Application No. 57-9344 that the shift and select levers are installed approximately perpendicular to the cab floor. There is.

[Purpose of invention]

This idea was devised to make the technology related to the above-mentioned measures even more effective, and specifically, it ensured the ground clearance of the radiator and increased the operational stability of the gear shift lever. be.

[Means for solving problems]

The basic structure of the present invention to achieve the above object is a cab-over type automobile in which a radiator is placed under the driver's seat, and a support shaft for a gear shift lever is placed on the side of the driver's seat. In a transmission remote control device for a cab-over type automobile equipped with a shift and select lever, the support shaft is arranged near the top of the cab floor, the shift and select lever are installed so as to be substantially parallel to the cab floor, and The connecting link rod is installed so as to be substantially perpendicular to the cab floor, and the support member of the support shaft is coupled to a fixing bracket that is fixed facing in the shift direction across the flat part and the inclined part of the cab floor. It is something to do.

[Effect of invention]

With the above configuration, the support shaft of the gear shift lever can be brought as close as possible to the cab floor without interfering with the rocking of the shift and select levers, making it possible to effectively utilize the vertical space and operating the gear shift lever. The force is absorbed by the strong fixed bracket, improving operational stability.

[Example of idea]

Examples of this invention will be described below with reference to FIGS. 4 to 6.

In the figure, 1 is a cab floor, 2 is a gear shift lever, and 3 is a support member.

The gear shift lever 2 has its support shaft 4 disposed near the top of the cab floor 1, and the shift lever 5 and select lever 6 installed on the support shaft 4 are installed facing parallel to the cab floor 1. There is. The speed change lever 2 is fixed to a support shaft 4 via a yoke 2a, and the support shaft 4 is swingably and rotatably supported by the support member 3 via a ball joint 4a. The shift lever 5 is integrally fixed to the yoke 2a, and the select lever 6 is attached to the support member 3 so as to be swingable about a shaft 6a, and an engaging portion 6b is provided at the end of the support shaft 4. It is engaged with the joint ball 4b. Therefore, when a select operation is performed using the shift lever 2, the support shaft 4 swings together with the shift lever 2, and the select lever 6 swings due to engagement with the joint ball 4b. Also, when you perform a shift operation,
The shift lever 5 integrated with the yoke 2a swings.
