Abstract
The utility model discloses a low-speed port towing vehicle with compressed natural gas (CNG) as fuel. The low-speed port towing vehicle comprises a vehicle frame, a one-side cab, a chassis and a towing saddle, wherein the one-side cab, the chassis and the towing saddle are arranged on the vehicle frame. An engine of the chassis is a special natural gas engine for CNG. Observation windows are arranged in the front portion, the rear portion, the left portion and the right portion of the one-side cab. A plurality of gas cylinders are arranged on the vehicle frame and used for supplying gas to the special natural gas engine for the CNG. The gas cylinders are arranged behind the one-side cab and on one side of the middle of the vehicle frame. The gas cylinders located behind the one-side cab are not higher than the rear observation window of the one-side cab. According to the low-speed port towing vehicle, a driver in the one-side cab can see the outside at 360 degrees so that the field of view is wide, the low-speed port towing vehicle is suitable for a special operating environment of a port, the CNG engine is adopted, the CNG gas cylinders are reasonably arranged on the vehicle frame, and therefore the sight line of a driver cannot be blocked, and the gas cylinders can be installed as many as possible to enable the engine to have sufficient gas sources.
Description
Technical field
The utility model relates to a kind of harbour low speed tractor.
Background technology
Develop rapidly along with national auto-industry, the domestic automobile transportation market becomes to reveal the trend of segmentation, the low speed wheel tractor is a class wherein, be mainly used in cargo transfer in the zones such as port and pier, stockyard, logistics centre, principal feature is that safety, reliability requirement are high, and low speed tractor horsepower is large, and manoevreability is good, the continuous working of working in three shifts, production efficiency is high.The fuel of present harbour low speed tractor is basically all take diesel oil as main, and in the face of increasingly serious energy shock and environmental issue country promotion use new forms of energy, the support development meets the vehicle of energy-saving, emission-reducing, environment friendly requirement energetically.CNG be compression natural gas have the advantages such as aerating convenience, low price at home the application of vehicle become a kind of trend, but on the special-purpose low speed tractor in harbour, also be not applied.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of harbour low speed tractor take CNG as fuel is provided.
In order to solve the problems of the technologies described above, the utility model comprises vehicle frame, is arranged on one-side cab, chassis and traction saddle on the vehicle frame, the driving engine on described chassis is the special-purpose natural gas engine of CNG, one-side cab all have observation window all around, vehicle frame is provided with a plurality of gas cylinders to the special-purpose natural gas engine air feed of CNG, gas cylinder is arranged on a side at the rear side of one-side cab and vehicle frame middle part, and the gas cylinder that is positioned at the rear side of one-side cab is not higher than observation window behind the one-side cab.
For arrangement convenience, the special-purpose natural gas engine of described CNG is arranged on frame inside and is positioned at the below of one-side cab.
For the ease of aerating, described vehicle frame is provided with and adds gas port, adds the edge that gas port is arranged on vehicle frame one side, and all gas cylinders are connected to by tracheae and add on the gas port.
For easy to operate, the change-speed box on described chassis adopts automatic transmission with hydraulic torque converter.
Described chassis comprises propons and back axle, and propons is steeraxle, and back axle is drive axle.
The beneficial effects of the utility model are: operator's compartment 360 degree of the present utility model are visual, broad view, be suitable for the special operating environment in harbour, adopt the CNG driving engine, reasonably be arranged in the CNG gas cylinder on the vehicle frame, sight line that neither can the overslaugh chaufeur can be installed gas cylinder as much as possible again, makes driving engine have sufficient source of the gas.
Description of drawings
