Abstract

The invention relates to the provision of transport of equipment through water barriers, can be used in the design and manufacture of lightweight bodies of tracked floating vehicles and serves to increase the reliability of the body, reduce mass and reduce metal consumption. The caterpillar floating vehicle’s body is equipped with a box-shaped frame at the bottom, including torsion beams, the suspension side brackets of which are supported by integral side spars, attached along the axis of the suspension bracket brackets with a webbing rigidly connected to the upper longitudinal span, which in turn connects the side side members . The joints of the composite side spars are aligned with the axles of the frames.

The invention relates to the provision of transport of equipment through water barriers and can be used in the design and manufacture of lightweight bodies of tracked floating vehicles.

The aim of the invention is to facilitate the construction of the body, reduce the number of transverse welds and undercuts of the base metal at the joining joints of the side members, eliminate the need to manufacture reinforcement parts for the joints of the side members, reduce the consumption of sheet and corner rolling and the complexity of manufacturing the bodies and strengthen the upper power section of the side member.

The goal is achieved by transferring the junction of the side members to the axis of the webbing, the basis of which are torsion beams closed along the bottom with

side spars through the brackets of the suspensions forming the bottom reinforcement of the joint of the spars and shortening its length. The presence of vertical struts overlapping the joint is its reinforcement.

Figure 1 shows the caterpillar floating vehicle body, view of the spar; figure 2 is the same, a longitudinal section; in Fig.Z - the same, a transverse section along the axis of the frame; figure 4 is the same, top view.

The caterpillar floating vehicle body includes a torsion beam 1 (Fig. - which is the base of the frames of the frame equipped with a bottom 2 and composite side members 3 and 4, the joint of which is located on the axis of the frame side of the body. The composite side members 3 and 4 on top are connected by a rigid longitudinal along catfish 5, on which the tracked superstructure is supported.

lock 6. Torsion beam 1 includes a longitudinal beam 7 (Fig. 2), rigidly connected to the bottom 2 and suspension brackets 8, on which vertical posts 9 are mounted, rigidly connected to the composite spars 3 and 4, as well as to the longitudinal som 5. The lower body tie are longitudinal split profiles 10 and 11, rigidly connected with the bottom 2, composite side members 3 and 4 and suspension brackets 8. The vertical struts 9 are inclined (Fig. 3) and abut against the lower corner of the longitudinal CA 5, forming with the composite side members 3 and 4 of the bulb profile, on the protruding shelf of which the caterpillar wing wing is supported 6. The connection of the composite side members 3 and 4 is closed in a box section (Fig. 4) formed by a vertical strut 9.

In the process of operating tracked vehicles, the loads on the track rollers are transmitted through the housing, directly through the longitudinal c from 5 to the vertical racks 9, supported by the suspension brackets 8, in which the axles of the tracker track balancers are fixed. At the same time, the load is transferred to the joint of the composite side members 3 and 4. Placing it along the line of application of force excludes the possibility of its kink, since it works on compression in conjunction with a vertical stand 9. Base0

At the junction of the composite side members is the suspension bracket 8, which, together with the bottom 2 and profiles 10 and 11, constitutes a tensile casing.

The combination of the joints of the composite side spars with the axis of the frame avoids additional reinforcing elements 6, and, therefore, provides a reduction in the length of welds and the consumption of fillet, which is used as a compensator on the prototype, and also reduces the weight of the body and the complexity of its manufacture. In addition, this technical solution makes it possible to strengthen the upper power strut from the side member.
