Problems solved by technology

[0006] However, the reinforcement structure of the driver's cab 1 so far only corresponds to the conventional test in which the upper surface of the driver's cab 1 is hit with the impact head 2' and a load is applied in the vertical direction. For example, image 3 In the same way as shown in the indoor view of the backboard 4 on the conventional cab 1, the reinforcement beam 5 is installed on the upper wall surface of the indoor side of the backboard 4 throughout the entire area in the vehicle width direction, and at the same time, the above-mentioned backboard 4 A pair of reinforcing columns 10, 11, which stand upright from the floor 9 directly above the rear cab brackets 7, 8 supporting the rear of the cab 1 from the side of the frame 6 and are

Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] Figure 4 shows an example of the mode of carrying out the present invention, and gives the same image 3 Parts with the same reference numerals represent the same items.

[0028] exist Figure 4 In the example illustrated in the image 3 In the case of the conventional structure shown in the same, the wall surface of the indoor side of the backboard 4 of the cab 1 is installed with a reinforcement beam 12 and a reinforcement column 13, 14 for reinforcement, but with the backboard 4 top of the cab 1 as the slave vehicle The two parts where the outer end of the width direction enters the inner side with the required length are load support points A and B, and a pair of reinforcement columns 13 and 14 are installed on the aforementioned back plate 4 to be connected to support the aforementioned steering wheel from the frame 6 side. Between the bottom plate 9 di...

Abstract

Two locations drawn inward from vehicle-widthwise outside ends in the top part of a back panel (4) of a cab (1) are designated as load support points (A, B), a pair of reinforcing studs (13, 14) are attached to the back panel (4) so as to connect the load support points (A, B) and a floor (9) directly above a pair of rear-side cab mountings (7, 8) supporting the rear part of the cab (1) from a frame (6) side, a reinforcing beam (12) is attached to the back panel (4) so as to connect the top ends of the reinforcing studs (13, 14) together, and the unreinforced parts on the vehicle-widthwise sides of the reinforcing beam (12) remain as impact-absorbing parts (15, 16).

Description

technical field [0001] The present invention relates to a cab reinforcement structure. Background technique [0002] In recent years, especially in Europe and other places, vehicle regulations have become more and more stringent. For example figure 1 As shown, for a flat-headed large truck, etc., it is planned to hit the upper side of the driver's cab 1 with the impact head 2, first give a side impact, and then figure 2 As shown, the upper surface of the roof panel 3 of the cab 1 is impacted with another impact head 2', and the strength test is a strength test in which a load is applied in the vertical direction. [0003] That is, the strength of the driver's cab 1 when this new strength test test rolls over, when actually rolling, since the driver's cab 1 is the state of rollover at first, after adding a side impact to the upper side of the driver's cab 1, Due to the further rolling, the cab 1 is in a bottom-up state (rolling 180°), and a load in the downward direction ...
