Abstract
The utility model discloses a transmission mechanism of a 8 multiply 8 light type entire region vehicle driven in a great variety of topographies such as mountain, marsh, desert, etc. A engine, a speed changing box, a steering transmission case, a chain, and wheels are connected in sequence, the power input of the steering transmission case is connected with the speed changing box, and is simultaneously connected with a header box through the chain, and the header box is further connected with a hydraulic motor, a hydraulic pump, and the engine in sequence. The operation steering can control the oil supply flow quantity and the direction of the hydraulic pump, the hydraulic motor rotates to make two output axles of the header box reversely rotate, through the steering transmission case, the two output axles have the speed difference, thereby the purpose of the complete vehicle speed difference steering is realized, and the flexibility and the reliability of the steering are enhanced. The deficiencies that the steering working efficiency existing in the prior art is low, the frictional abrasion is large and the reliability is poor when braking, and the original position steering cannot be realized are overcome.
Description
Technical field
The utility model relates to a kind of 8x8 light type gearing mechanism of whole clime car, transmission device that especially can the 8x8 light type pan terrain vehicle that maneuverability travels in multiple landform such as mountain region, marsh, rivers, desert.
Background technology
At present, the transmission device of known 8x8 light type pan terrain vehicle is that driving engine, change speed gear box, steerage gear case, chain, wheel are linked in sequence, two groups of power about wherein the steerage gear case is told, directly pass to the 4th wheel by chain, the 4th is directly passed to power the 3rd wheel by chain, the 3rd is directly passed to power the 2nd wheel by chain, and the 2nd is directly passed to power the 1st wheel by chain.Thereby realize that 8 take turns driving simultaneously, improve the ability that car load adapts to complex-terrain.When turning to, by an edge trig, rotate on one side, realize differential steering.But this inefficiency that turns to, big, the poor reliability of the skimming wear of glancing impact, can not realize in-situ transesterification to.
Summary of the invention
The purpose of this utility model is to provide a kind of 8x8 light type gearing mechanism of whole clime car.
The purpose of this utility model can reach by following technical measures, it is this 8x8 light type gearing mechanism of whole clime car, its driving engine is connected with change speed gear box, transmission shaft, steerage gear case, two groups of power about the steerage gear case is told, directly pass to IV axle wheel by chain, the III axle directly passes to power II axle wheel by chain, the II axle directly passes to power I axle wheel by chain, its key is: the steerage gear case is connected with change speed gear box on the one hand, is connected with header box by chain simultaneously; Header box is connected with HM Hydraulic Motor, and HM Hydraulic Motor is connected with Hydraulic Pump, and another delivery port of Hydraulic Pump and driving engine is connected.
Arranged three shaft gears in the housing of header box, three shaft gears are meshing with each other, and wherein one links to each other with HM Hydraulic Motor, and all the other two link to each other with the steerage gear case by chain.When turning to, the power of driving engine is divided into two groups, and one group passes to the steerage gear case by change speed gear box, transmission shaft; Another group passes to the steerage gear case by belt, Hydraulic Pump transmission shaft, Hydraulic Pump, oil pipe, HM Hydraulic Motor, header box, chain.The steerage gear case will make two output shafts that velocity contrast is arranged after two groups of power are converged, thereby realize continuous turning, realize steadily accurate again direction control, and its turning velocity is fast, high efficiency.
