Description

The two car bodies of crawler type

Technical field: the present invention relates to a kind of extraordinary cross-country car, relate in particular to a kind of crawler type binary cross-country car.

Background technology: crawler type binary cross-country car is a kind of extraordinary cross-country car of high speed that is used for landform such as mountain region, snowfield, marsh, river shoal, desert, gully.Because operating environment is complicacy, abominable very, the steering hardware of car body must have the requirement that multi-aspect rotational freedom could satisfy high maneuverability ability and powerful obstacle climbing ability before and after therefore requiring to be used to connect.Yet though the also multi-aspect rotational freedom of tool of the steering hardware of present crawler type binary cross-country car, because damping mechanism is not set, therefore in traveling process, forward and backward car body jolts very serious, and cruising characteristic and traveling comfort are relatively poor; In addition, the crawler belt of present crawler type binary cross-country car does not have the slip-off preventing function, and therefore crawler belt comes off easily and leads to grave accident in the process of running at high speed; The 3rd, present crawler type binary cross-country car does not have water-skiing device, therefore can only not have the function of paddling at land locomotion.

Summary of the invention: to the above-mentioned defective that exists in the prior art; The present invention aims to provide and a kind ofly can prevent that crawler belt from coming off; Existing flexible performance and powerful obstacle climbing ability, again good cruising characteristic and traveling comfort are arranged, also have the two car bodies of crawler type of amphibious function simultaneously.

To achieve these goals; The present invention adopts following technical scheme: it comprises front vehicle body, aftercarriage, is connected the steering hardware between this two car body; Said front vehicle body is made up of the preceding chassis that is provided with two slat gum crawler belts, the front compartment that is located on this preceding chassis, and said aftercarriage is made up of the back chassis that is provided with two slat gum crawler belts, the trunk that is located on this back chassis; The back side of rubber belt track has two rows to keep the side tooth of wipe contact separately with drive wheel two outer faces; There are the two row's center tooth that are distributed between two row's side teeth at the back side of this rubber belt track, this two rows center tooth separately be distributed in the engagement of the circle of two on drive wheel wheel face teeth groove; Steering hardware is by the preceding free bearing on the chassis before being fixed on; Be fixed on the back free bearing on the chassis of back; Preceding bindiny mechanism before being hinged on the free bearing; Cylinder body is hinged in this preceding bindiny mechanism and piston rod is hinged on the forward horizontal stand oil cylinder on the front compartment; With bindiny mechanism behind the preceding bindiny mechanism pivotally attached; Be hinged on the back free bearing on and with this back bindiny mechanism pivotally attached turning set; Piston rod is hinged on this turning set and cylinder body and trunk pivotally attached back balance oil cylinder; Cylinder body is hinged on back bindiny mechanism's left and right sides and piston rod respectively and turns to oil cylinder to constitute with two of preceding bindiny mechanism left and right sides pivotallys attached separately.

Said drive wheel left driving wheel, right drive wheel is involutory is formed by fixedly connecting, the wheel face of left driving wheel and right drive wheel respectively is provided with a circle teeth groove; Surface distribution at rubber belt track has the outwards anti-slop serrations of protrusion of two rows.

Compare with prior art; The present invention is owing to adopted technique scheme; Hydraulic efficiency gear and connecting mechanism are organically combined; Therefore turn to oil cylinder can make deflection angle that reaches 40 ° of formation between the forward and backward car body through controlling two, thereby realize the vehicle quick steering and reduce turn radius; In addition; Through complex-terrain the time; Not only can be between the forward and backward car body through cooperating to form and reverse between back bindiny mechanism and the turning set; But also can through between preceding free bearing and the preceding bindiny mechanism cooperate or turning set and back free bearing between cooperate and between forward and backward car body, form one or the angle of bowing or facing upward, thereby improved vehicle greatly through the flexible performance of complex-terrain and the ability of clear an obstacle; Owing in preceding bindiny mechanism, be provided with piston rod and front vehicle body pivotally attached forward horizontal stand oil cylinder, on turning set, be provided with cylinder body and aftercarriage pivotally attached back balance oil cylinder; Therefore can make front vehicle body or aftercarriage depart from the chassis up and down and reach about 15 °, thereby the amplitude of jolting when having reduced vehicle, improve cruising characteristic and traveling comfort through complex-terrain.Moreover, owing to adopted the surface to be provided with the rubber belt track of anti-slop serrations, so rubber belt track can play the effect of water-skiing device in water, and vehicle has amphibious function.The 3rd and since be provided with at the back side of crawler belt two rows can with the teeth groove ingear center tooth on the drive wheel, therefore can guarantee not skid between crawler belt and the drive wheel, not only avoided crawler belt to come off effectively, but also improved running efficiency and safe reliability; In addition, can keep wipe contact with the left and right end face of drive wheel, therefore further reduce the possibility of crawler belt slippage owing to be located at two row's side teeth at the crawler belt back side.
