Abstract
The utility model relates to the field of dump trucks, and in particular relates to an auxiliary power pull-type dump truck. The dump truck consists of a head axle (1) and a trailer axle (2). The dump truck is characterized in that the trailer axle (2) is auxiliary driven by using a hydraulic system; the hydraulic system comprises a hydraulic pump (4) and a trailer hydraulic motor (7); the hydraulic pump (4) is in transmission connection with a head engine (3) in the head axle (1); the output end of the hydraulic pump (4) is in transmission connection with the trailer hydraulic motor (7); and the trailer hydraulic motor (7) is connected with a pull wheel (8). The dump truck has high bearing capacity, and the using condition is greatly improved, so that the service life of the pull-type dump truck is prolonged.
Description
Technical field
The utility model relates to dumping car field, particularly a kind of auxiliary power pulling type dumping car.
Background technology
The pulling type dumping car is due to its large-tonnage load carrying ability, and bringing into play very important effect in national economy.Articulated vehicle is by carrying additionally the different casees that drags, and transport capacity is also different, objectively if the general transport liquid of tank car or dust and so on need the sealing transportation.General open type drags the case traffic coverage very large, if be no more than carrying capacity can, such as carrier, electromechanical appliance etc. can.Articulated vehicle is because load carrying ability is very large, so enough propulsive efforts demand to propulsive effort when adapting to climbing must be arranged.
Summary of the invention
The purpose of this utility model is in order to overcome the existing deficiency of pulling type dumping car of the prior art, a kind of auxiliary power that can improve pulling type dumping car hill climbing ability is provided, its load-carrying capacity is strong, and applying working condition improves greatly, thereby has extended the service life of pulling type dumping car.
The technical scheme that its technical matters that solves the utility model adopts is: auxiliary power pulling type dumping car, it is to be made of headstock vehicle bridge and towed vehicle vehicle bridge, it is characterized in that: the towed vehicle vehicle bridge by hydraulic efficiency pressure system as assistive drive, hydraulic efficiency pressure system comprises Hydraulic Pump and towed vehicle HM Hydraulic Motor, headstock driving engine in Hydraulic Pump and headstock vehicle bridge is in transmission connection, the hydraulic pressure delivery side of pump is connected with the towed vehicle hydraulic motor transmission, the towed vehicle HM Hydraulic Motor again with pull wheel and be connected.
Described headstock driving engine is connected with the headstock wheel drive with Hydraulic Pump respectively.
Described headstock driving engine only is connected with hydraulic pump driving, and Hydraulic Pump is exported two groups of power, is connected with headstock HM Hydraulic Motor and towed vehicle hydraulic motor transmission respectively, and the headstock HM Hydraulic Motor is connected with the headstock wheel drive.
To be this auxiliary power pulling type dumping cars pull in pulling type dumping car rear end the beneficial effects of the utility model that auxiliary power is set.Provide auxiliary power by the engine drive hydraulic efficiency pressure system to the towed vehicle wheel.Thereby improve pulling type dumping car hill climbing ability, its load-carrying capacity is strong, and applying working condition improves greatly, has extended service life.
Description of drawings
Below in conjunction with the embodiment accompanying drawing, the utility model is further illustrated:
Fig. 1 is that this auxiliary power pulling type self-unloading vehicle bridge is driven the form structure schematic diagram;
Fig. 2 is the complete hydraulic-driven form structure of this auxiliary power pulling type dumping car schematic diagram;
In figure: 1, headstock vehicle bridge; 2, towed vehicle vehicle bridge; 3, headstock driving engine; 4, Hydraulic Pump; 5, headstock HM Hydraulic Motor; 6, headstock wheel; 7, towed vehicle HM Hydraulic Motor; 8, pull wheel.
The specific embodiment
this auxiliary power pulling type dumping car is to be made of headstock vehicle bridge 1 and towed vehicle vehicle bridge 2, wherein towed vehicle vehicle bridge 2 by hydraulic efficiency pressure system as assistive drive, hydraulic efficiency pressure system comprises Hydraulic Pump 4 and towed vehicle HM Hydraulic Motor 7, headstock driving engine 3 in Hydraulic Pump 4 and headstock vehicle bridge 1 is in transmission connection, drive Hydraulic Pump 4 by headstock driving engine 3, the mouth of Hydraulic Pump 4 and towed vehicle HM Hydraulic Motor 7 are in transmission connection, towed vehicle HM Hydraulic Motor 7 again with pull wheel 8 and be connected, the towed vehicle HM Hydraulic Motor 7 that Hydraulic Pump 4 drives on the towed vehicle vehicle bridge, towed vehicle HM Hydraulic Motor 7 drives pulls wheel 8, to realize assistive drive.
Due to headstock driving engine 3 drive hydraulic system principles that pass through in headstock vehicle bridge 1, provide assistive drive by hydraulic efficiency pressure system to the wheel 8 of pulling of towed vehicle vehicle bridge 2 again, thereby improve pulling type dumping car hill climbing ability, its load-carrying capacity is strong, applying working condition improves greatly, has extended service life.
As shown in Figure 1, the headstock driving engine 3 of the auxiliary power pulling type dumping car of the present embodiment is in transmission connection with Hydraulic Pump 4 and headstock wheel 6 respectively, and headstock wheel 6 is directly to drive by headstock driving engine 3, and this kind mode is that bridge drives.
as shown in Figure 2, the headstock driving engine 3 of the auxiliary power pulling type dumping car of the present embodiment only is in transmission connection with Hydraulic Pump 4, two groups of power of 4 output of Hydraulic Pump, be in transmission connection with headstock HM Hydraulic Motor 5 and towed vehicle HM Hydraulic Motor 7 respectively, headstock HM Hydraulic Motor 5 is in transmission connection with headstock wheel 6, headstock driving engine 3 drives Hydraulic Pump 4, drive respectively headstock HM Hydraulic Motor 5 and towed vehicle HM Hydraulic Motor 7 by Hydraulic Pump again, headstock wheel 6 provides power by headstock HM Hydraulic Motor 5, pull 8 of wheels and provide power by towed vehicle HM Hydraulic Motor 7, this kind mode is complete hydraulic-driven.
The parts that the present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
