Anti-impact protection device for vehicle transfer case

Abstract

The invention belongs to the field of vehicle protection, and particularly relates to an anti-impact protection device for a vehicle transfer case. The anti-impact protection device comprises a double-V-shaped bottom plate, a front baffle and a rear baffle, the double-V-shaped bottom plate is of an axial symmetry structure, one side of the double-V-shaped bottom plate sequentially comprises a first inclined plate, a second inclined plate, a vertical plate and a protruding edge from bottom to top, the two first inclined plates located on the lowermost side are connected to form a V shape, one sides of the second inclined plates are connected with the first inclined plates, the other sides of the second inclined plates are connected with the vertical plates, the protruding edges are arrangedon the other sides of the vertical plates, bolt holes are formed in the protruding edges, the front baffle and the rear baffle are arranged at the two ends of the double-V-shaped bottom plate correspondingly, and through holes are formed in the front baffle and the rear baffle correspondingly. The protection device can effectively resist collision, explosion and other impacts, protect a transfercase driving power system and enhance the heat dissipation capacity of the transfer case, and meanwhile, the protection device can be conveniently installed on a vehicle as an independent protection module and is convenient to maintain and replace.

Description

technical field [0001] The invention belongs to the field of vehicle protection, and in particular relates to an anti-shock protection device for a vehicle transfer case. Background technique [0002] Military vehicles are often required to have good mobility and off-road capabilities. The battlefield road conditions and environments faced during use are more complex. Scratching and collision accidents are prone to occur at the bottom of the vehicle, especially in the face of explosive impacts such as landmines and improvised explosive devices. The transfer case is at a lower position in the chassis layout and is close to the explosion point. Its shell is usually made of aluminum alloy or cast iron, and its internal structure is compact.

[0002] Military vehicles are often required to have good mobility and off-road capabilities. The battlefield road conditions and environments faced during use are more complex. Scratching and collision accidents are prone to occur at the bottom of the vehicle, especially in the face of explosive impacts such as landmines and improvised explosive devices. The transfer case is at a lower position in the chassis layout and is close to the explosion point. Its shell is usually made of aluminum alloy or cast iron, and its internal structure is compact. The transfer case is easily damaged under the impact of the explosion. vehicle incapacitated

[0003] At present, military vehicles usually use V-shaped structure to strengthen the bottom protection in the design, and the gearbox is wrapped in the protective structure. Due to the constraints of vehicle mobility and ground clearance, the safety gap between the protective structure and the transfer case is usually Smaller, the protective structure is easy to collide with the transfer case under the impact of the explosion, and it is difficult to meet the protection requirements. At the same time, the closed structure of the overall package affects the heat dissipation of the transfer case, which leads to the continuous rise of the temperature of the transfer case, which seriously affects the safety of the transfer case.
