Abstract

The utility model relates to a two-bridge hinged dump truck, belonging to the field of transport machinery. The two-bridge hinged dump truck total has two bridges, and the carriage of the two-bridge hinged dump truck total is a hydraulic dump carriage. The two-bridge hinged dump truck is characterized in that, for the two-bridge hinged dumping, a front bridge and a front truck frame are connected through a front suspension, a rear bridge and a rear truck frame are connected through a rear suspension, and both the front suspension and the rear suspension are steel leaf spring suspensions. The two-bridge hinged dump truck has the following beneficial effects: the structure is not limited by the primary structure form; the steel leaf spring suspensions which have simple manufacturing processes and relatively low cost and are commonly used in the market at present are used to replace air-hydraulic suspensions which have complicated manufacturing processes and relatively high cost and are rarely used in the market at present, so that the cost is greatly reduced without decreasing the performance of the whole dump truck or just decreasing a little, the price performance ratio of products is increased, and the popularization is facilitated; and particularly, the superiority of the two-bridge hinged dump truck is more obvious when the two-bridge hinged dump truck is used in small-scale hinged dump trucks.

Description

A kind of two bridge hinge type dumping cars

Technical field:

The utility model relates to a kind of hinge type dumping car, specifically relates to a kind of two bridge hinge type dumping cars that adopt the steel spring suspension, belongs to field of transport machinery.

Background technology

Disclosed two bridge hinge type dumping cars on the market up to now, the air hydraulic suspension is all adopted in being connected between its vehicle bridge and the vehicle frame, though this suspension superior performance, but manufacturing process complexity, application in the market is rare, cost is relatively costly, be unfavorable for promoting, especially under lower-powered situation, seem that especially cost is too high.

The utility model content:

In order to overcome the deficiency that prior art exists, the purpose of this utility model is a kind of manufacturing process simple, and generally use, cost is lower, the steel spring suspension application that helps promoting is to this two bridge hinge type dumping cars, particularly be applied on the two more small-sized bridge hinge type dumping cars, its advantage is more remarkable.

In order to achieve the above object, the technical solution of the utility model realizes in the following manner, a kind of two bridge hinge type dumping cars, comprise front vehicle frame, driving engine, front suspension, front-wheel, propons, front propeller shaft, auxiliary gear box, articulated body, back one transmission shaft, the bearing seat assembly, back two transmission shafts, rear suspension, trailing wheel, back axle, back vehicle frame, the compartment, the self-unloading oil cylinder, operator's compartment, maneuvering system, last transmission shaft, change speed gear box, power-transfer clutch, turn to oil cylinder, wherein front vehicle frame is connected by articulated body between the vehicle frame with the back, this articulated body has the degree of freedom on the both direction, make front vehicle frame can rotate relative to the vertical axes of articulated body between the vehicle frame with the back, also can rotate simultaneously relative to the horizontal shaft of articulated body, car load has two vehicle bridge, the compartment is the hydraulic dump hoist railway carriage or compartment, described two bridge hinge type dumping cars, be connected with front suspension between its propons and the front vehicle frame, back axle is connected with rear suspension between the vehicle frame with the back, front suspension and rear suspension are the steel spring suspension, here said steel spring suspension is meant that steel spring is that the whole or steel spring of suspension is one of major part of suspension.Its objective is for aspect the traveling comfort of the vibration that reduces each parts more than the suspension, raising chaufeur, keep close with existing aerodynamic force suspension.

The beneficial effects of the utility model are: its structure is not subjected to the restriction of original structure form, with manufacturing process simply, generally use in the market, steel spring suspension that cost is cheap relatively replaces the manufacturing process complexity, use rare and the relatively costly air hydraulic suspension of cost in the market, make its complete machine performance not reduce or reduce under the less situation, cost reduces greatly, improved cost performance of product, and help promoting, especially on the more small-sized hinge dumping car time, advantage is more obvious.

The specific embodiment

A kind of two bridge hinge type dumping cars comprise: front vehicle frame 1, driving engine 2, front suspension 3, front-wheel 4, propons 5, front propeller shaft 6, auxiliary gear box 7, articulated body 8, back one transmission shaft 9, bearing seat assembly 10, back two transmission shafts 11, rear suspension 12, trailing wheel 13, back axle 14, back vehicle frame 15, compartment 16, self-unloading oil cylinder 17, operator's compartment 18, maneuvering system 19, go up transmission shaft 20, change speed gear box 21, power-transfer clutch 22, turn to oil cylinder 23.Driving engine 2, power-transfer clutch 22, change speed gear box 21, auxiliary gear box 7, operator's compartment 18 are installed on the front vehicle frame 1, and compartment 16 is installed on the vehicle frame 15 of back.Front vehicle frame 1 is connected by articulated body 8 with back vehicle frame 15, because articulated body 8 has the degree of freedom on the both direction, so can rotate relative to the vertical axes 24 of articulated body 8 between front vehicle frame 1 and the back vehicle frame 15, also can rotate relative to the horizontal shaft 25 of articulated body 8 simultaneously.Turn to oil cylinder 23 to be connected between front vehicle frame 1 and the back vehicle frame 15, be used for realizing turning to.Propons 5 is connected by front suspension 3 with front vehicle frame 1.Back axle 14 is connected by rear suspension 12 with back vehicle frame 15.Self-unloading oil cylinder 17 is installed between compartment 16 and the back vehicle frame 15, is used for realizing self-unloading.The power of driving engine 2 passes to change speed gear box 21 by power-transfer clutch 22, pass to auxiliary gear box 7 by last transmission shaft 20 again, auxiliary gear box 7 is with the power separated into two parts, power forward passes to propons 5 by front propeller shaft 6, power backward passes to bearing seat assembly 10 by back one transmission shaft 9, passes to back axle 14 by back two transmission shafts 11 again.The connection mode of other parts is same as the prior art, repeats no more here.Wherein back one transmission shaft 9, bearing seat assembly 10 not necessarily, the power of auxiliary gear box also can directly be delivered to back axle 14 by back two transmission shafts 11.Wherein propons 5, back axle 14 are drive axle.Above-mentioned auxiliary gear box is mainly used to transmission of power is divided into former and later two directions, and auxiliary gear box can have the engage a gear device, can be power cut backward, make vehicle have only propons to drive, just use rear-axle drive when needing, also can not be with the engage a gear device, make back axle often be in driving condition.Auxiliary gear box also can have speed changing function simultaneously, also can not have speed changing function.
