Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cooling fan shroud and a radiator screen for engine-powered vehicles.

The invention particularly relates to radiators for industrial vehicles, such as engine powered forklift trucks.

[Conventional technology]

In engine-powered vehicles, a radiator that cools engine cooling water is placed opposite the engine.
The fan driven by the engine generates air for cooling the radiator, and the tip of the shroud bracket screwed to the radiator is extended to the vicinity of the fan, so that the cooling air generated by the fan can effectively cool the radiator. I'm trying to cool it down.

An example of a conventional radiator section is shown in FIG. In FIG. 3, radiator screen mounting rails 1a having a U-shaped cross section are provided on both left and right sides of the fan shroud 1, and the radiator screen 4 is inserted into these rails 1a. The radiator screen 4 consists of a rectangular frame 4a and a screen 4b stretched over the frame.
Prevent foreign matter from being sent to the radiator core. A forked shroud bracket 7 is integrally attached to the upper part of the frame 4a of the radiator screen 4, and the slit portion 7a of the shroud bracket 7 is inserted into the bolt 2a protruding from the radiator 2. The radiator screen 4, which is mounted on the rail 1a by tightening nuts 6, is fixed to the radiator 2 by a shroud bracket 7. Note that 4e is a handle attached to the upper part of the frame 4a.

[Problem that the invention attempts to solve]

In the above-mentioned conventional device, since the fan shroud 1 is fixed via the radiator screen inserted into the rail 1a of the fan shroud 1, there is a problem in that the vibration of the fan shroud 1 is large. Therefore, it is necessary to remove the nut 6 each time the radiator screen 4 is attached or detached, and there is a problem that the radiator screen 4 cannot be easily detached or attached during cleaning or the like.

[Means for solving problems]

In the present invention, a pair of radiator screen mounting rails are provided on the sides of the fan shroud, a shroud bracket is integrally attached to the upper part of the fan shroud, and a handle is provided laterally protruding from the upper part of the radiator screen.
The above-mentioned problem is solved by a radiator screen clamp in which a screen clamp for holding the handle is provided on the upper part of the shroud bracket, and the shroud bracket can be screwed onto the radiator.

[Effect]

In the present invention, since the shroud bracket, which is integrally attached to the upper part of the fan shroud, is screwed onto the radiator to fix the shroud itself, the vibration of the shroud can be reduced.

In addition, in this invention, the radiator screen is inserted into the pair of left and right rails provided on the fan shroud, and the radiator screen is fixed by holding the handle that protrudes laterally from the top of the radiator screen in the clamp on the top of the fan shroud. The screen can be attached and detached easily and quickly, improving the serviceability of the radiator screen.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments of the present invention.

In FIG. 1, radiator screen mounting rails 1a having a U-shaped cross section are provided on both left and right sides of a fan shroud 1, and a radiator screen 4 is inserted into these rails 1a. The radiator screen 4 consists of a rectangular frame 4a and a screen 4b stretched over the frame, and prevents foreign matter from being sent to the radiator core of the radiator 2. A handle 4c projects laterally from the upper part of the frame 4a of the radiator screen 4.

A shroud bracket 3 having an L-shaped cross section is integrally attached to the upper part of the fan shroud 1, and connects a pair of left and right rails 1a. A horizontal notch 3a is formed in the shroud bracket 3 to correspond to a bolt 2a projecting from the radiator 2. Further, a clamp 5 is provided on the upper surface of the shroud bracket 3. The clamp 5 of this embodiment includes a bracket 5a made of a steel plate bent in the shape of a key hand, and a gap extending in the longitudinal direction of the radiator bracket 3, which is welded to the upper surface of the bracket 5a and is used to fit the handle 4c of the radiator screen 4. It consists of a catch 5b having a diameter 5c. 〓 5c
The width of the handle 4c is set to be slightly smaller than the diameter of the handle 4c of the radiator screen 4, and the handle 4c is held by the spring action of the stopper 5b.

In addition, as the clamp of the present invention, a flat magnet may be used in place of the stopper 5b having the gap 5c, and the handle 4c of the radiator screen 4 may be clamped by magnetic attraction. Further, the bracket 5a may be omitted as appropriate.

In the device of the above embodiment having the above-described configuration, the radiator screen 4 is connected to the rail 1 of the radiator 1.
a from above, and the handle 4c is held by a clamp 5 provided on the shroud bracket 3 by fitting or magnetic attraction. A notch 3a of a shroud bracket 3 integrally attached to the radiator 1 is engaged with a bolt 2a fixed to the radiator 2, and a nut 6 is screwed onto the bolt 2a to fix the shroud 1 to the radiator.

[Effect of idea]

In the present invention, since the shroud bracket, which is integrally attached to the upper part of the fan shroud, is screwed onto the radiator to fix the shroud itself, the vibration of the shroud can be reduced.

In addition, in this invention, the radiator screen is inserted into the pair of left and right rails provided on the fan shroud, and the radiator screen is fixed by holding the handle that protrudes laterally from the top of the radiator screen in the clamp on the top of the fan shroud. The screen can be attached and detached easily and quickly, improving the serviceability of the radiator screen.
