Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] The cab according to the invention can be used in various engineering machinery vehicles, such as (crawler) excavators, bulldozers, road rollers, cranes and the like. figure 1 A perspective view of the cab 1 according to an embodiment of the present invention is shown, in which arrow A indicates the vehicle width direction (lateral direction), arrow B indicates the vehicle length direction (longitudinal direction), and arrow C indicates the vertical direction. The cab comprises four vertically or slightly obliquely extending structural members or struts 2a, 2b, 2c and 2d (wherein although only the lower end of strut 2d is shown, strut 2d is substantially similar in construction to the other struts). These pillars are made of high-strength rigid material such as steel, and are connected and fixed together by the top 5 and the four side wall parts 6...

Abstract

The invention provides a driver's cab with high structural strength, while the driver's cab can also maintain good shock absorption and sealing performance. A driver's cab for construction machinery vehicles, comprising a cab main body and an elastic load-bearing installation mechanism for mounting the cab main body on a wing plate constituting a part of the vehicle body structure, the cab main body includes at least three rigid Separate structural members of material and chamber roof and chamber side wall members connected between the structural members are mounted to the flaps by resilient load-bearing mounting means mounted at the ends where they meet the flaps. The present invention also provides an engineering machinery vehicle comprising the above cab.

Description

technical field [0001] The invention relates to a cab structure for construction machinery vehicles and a vehicle with the structure. Background technique [0002] The working environment of construction machinery vehicle drivers is generally quite harsh. Not only may there be a lot of dust near the cab, but also severe bumps may be caused due to uneven road surfaces. At the same time, this environment may also have many unpredictable dangers. In order to ensure the safety and comfort of the driver, it is desirable that the cab has higher strength, good vibration damping and sealing. [0003] Most of the current construction machinery vehicle cabs do not have reinforced supporting members, and their structural strength is difficult to meet safety requirements in some cases. The existing driver's cab is integrally installed on the frame structure or wing plate of the vehicle body through a plurality of elastic mounting parts. These elastic mounting parts can be, for example...
