This control device includes a brake pedal, a clutch pedal, master cylinders for operating the brakes and clutch, a steering device, and related piping. These are centrally arranged around the front protector. However, the space inside the front protector is extremely limited, for example in the case of hanging pedals on a forklift.
The above control devices are arranged and housed in a complicated manner. For this reason, work such as rough installation, inspection, and repair of the control device in this space is extremely difficult, and leakage of working fluid from piping connected to the control device may occur, resulting in a lack of reliability and durability. There was a problem.

[Purpose of the invention] The present invention solves the above-mentioned conventional problems, and improves the structural strength of the control device, simplifies the structure and arrangement by omitting the number of parts, simplifies installation work, and improves reliability. The object of the present invention is to provide a control device for an industrial vehicle that has improved reliability and durability and is advantageous in terms of cost.

[Structure of the invention] The industrial vehicle control device of the invention has a base attached to the front wall of the vehicle body, and a pair of arm-shaped open ends extending obliquely upward from the base. a steering device disposed along the longitudinal direction of the bracket and attached to the open end; a brake master cylinder fixed to the bracket in a state adjacent to each other and integrally coupled; It includes a clutch master cylinder and a shared piping for supplying working fluid from a working fluid source to the integrated brake master cylinder and clutch master cylinder. In the device of the present invention, the bracket attached to the front wall of the vehicle body has a cantilever-like structure consisting of a mounting portion and a pair of open ends, so that the shape of the vehicle body of the industrial vehicle to which it is applied is improved. , it can be selected in any shape depending on the space, etc., and can be easily and firmly attached to the front of the vehicle body. Further, the bracket can also be formed from a plate-shaped member, and the mounting portion and the open end portion can be easily manufactured by die-cutting in a press process or pressurization in a die-forming process.

[Operations and Effects of the Invention] The device of the present invention has a cantilever-like structure that includes a mounting portion and a pair of open ends, so that the bracket attached to the front wall of the vehicle body has a cantilever-like structure. The bracket consists of a carrier plate-shaped base that is attached to the front wall of the vehicle body and a pair of arm-shaped open ends that are integrally attached to the base, which strengthens the structure, reduces the number of parts, and simplifies the structure. This allows you to use space effectively. Since the brake master cylinder and the clutch master cylinder are integrally connected, it is possible to strengthen the structure, make it more compact, reduce the number of related parts, and reduce the weight. These integrated master cylinders are
By communicating with the working fluid source through a common piping, there is no need to install separate piping to each working fluid source, which simplifies piping, reduces the number of related parts, and reduces the space occupied. It is possible to place the right materials in the right places, making rough installation and removal easy, which is advantageous in terms of cost, and can improve reliability and durability. Further, the bracket may have a configuration in which the integrated brake master cylinder and clutch master cylinder are attached inside a pair of open ends, and a steering device is attached to the open ends at a position adjacent to the integrated brake master cylinder and clutch master cylinder. With such a configuration, each component can be installed in an orderly manner, and related components can be placed in the right places, allowing for efficient storage. Furthermore, the bracket has a structure in which the brake pedal and clutch pedal are rotatably supported on both sides of the pair of open ends, making it possible to place both pedals in the right place, making effective use of open space, and allowing both pedals to be placed in the right place. It can be easily operated and moved without any hindrance, and in particular,
In the case of a hanging pedal, there is a considerable degree of freedom in the arrangement and assembly of the pedal and related parts.

As described above, the device of the present invention has the function of arranging and attaching both master cylinders, the steering device, both pedals, etc. to the appropriate materials and locations, thereby making it possible to attach the related control devices to the bracket in advance. It can be used as an attachment that is installed in an orderly manner. Such an assembly allows for accurate, simple and quick installation and removal of the front protector on the vehicle body, and has the effect of significantly improving work efficiency.
