CN2778642Y - Luggage tractor - Google Patents

Abstract

The utility model discloses a luggage tractor comprising a vehicle frame, a motor, a hydraulic torque converter, a handbrake, a propeller axle, a driving axle, back wheels, front wheels, a steering wheel, a power steering machine, a direction machine, a brake and a back braking drum. The space between the steering wheel and the direction machine is equipped with the power steering machine; the space between the motor and the driving axle is equipped with the hydraulic torque converter; the front wheels and the back wheels are all equipped with braking devices. The generated rated traction force is increased to be available to the requirement of transporting quantity; the braking mode is the brake of the front wheels and the back wheels; the braking time is short. The transmission system of the utility model is added with the hydraulic torque converter to make the traction force have a bigger traction force in low speed running to be available to airport requirement. The utility model can replace the present commodity with a great popularization value.

Description

A kind of luggage tractor truck

One, technical field:

A kind of luggage tractor truck of the utility model, what relate to is that the airdrome luggage tractor truck manufactures and designs

Technical field.

Two, background technology:

In the market, be applied to the luggage tractor truck of carrying luggage on the airport, it is little that ubiquity tractive force, is difficult to satisfy present airport bulk goods and postal growing transportation request; Brake efficiency is low, is generally trailing wheel hydraulic drum braking, and not braking of front-wheel, so that can not give full play to the braking potential of tractor truck, poor stop occurs in the actual braking, easily and container want the problem of colliding; Driving system coupling has bigger tractive force according to tractor truck when the low speed, and earnestly the gear of change-speed box should be tried one's best simply, is convenient to operation, does not have turbine transformer owing in the driving system, can not give full play to the performance of low speed large traction; The product configuration is single, can not satisfy the requirement of different user to product.

Three, summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, reasonable configuration.Design a kind of new tractor truck.Its technology is to realize like this, the structure that comprises vehicle frame, driving engine, turbine transformer, hand braking, transmission shaft, axle drive shaft, trailing wheel, front-wheel, bearing circle, power steer, direction machine, drg, Back-braking drum, it is characterized in that: be provided with power steer between bearing circle and the direction machine, be provided with turbine transformer between driving engine and the axle drive shaft, front-wheel, trailing wheel all are provided with brake equipment.The positive effect of implementing after this technology is: at first overcome above-mentioned defective, rated drawbar pull increases, adapt to the requirement of transportation volume, brake mode is front-wheel, trailing wheel braking, and braking time is short, braking is stable, driving system increases turbine transformer, and bigger tractive force is arranged when making the tractive force low speed driving, adapts to the airport needs, can substitute existing product, the utmost point has promotional value.

Four, description of drawings:

Fig. 1 is the utility model keystone configuration scheme drawing,

Wherein, hand braking, the 5-transmission shaft of 1-vehicle frame, 2-driving engine, 3-turbine transformer, 4-, 6-axle drive shaft, 7-trailing wheel, 8-front-wheel, 9-bearing circle, 10-power steer, 11-direction machine, 12-drg, 13-brake wheel

Five, the specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

See accompanying drawing 1, the luggage tractor truck relies on vehicle frame (1) to be combined into one, and driving engine (2) connects turbine transformer (3), turbine transformer (3) connects hand braking (4), hand braking (4) connect transmission shaft (5), and transmission shaft (5) connects axle drive shaft (6), and axle drive shaft (6) connects two trailing wheels (7); Bearing circle (9) connects power steer (10), power steer (10) closure machine (11), and direction machine (11) connects two front-wheels (8); Drg (12) connects brake wheel (13).

See accompanying drawing 1, the electric switch of luggage tractor truck is opened, driving engine (2) starts, driving engine (2) drives turbine transformer (3), and example is selected two grades for use, turbine transformer (3) output shaft, drive axle drive shaft (6) by transmission shaft (5), drive two trailing wheels (7), make tractor truck to overtake by the rotation of axle drive shaft (6); When needs turned to, bearing circle (9) drove power steer (10), and power steer (10) drives direction machine (11), and is left or right, to front-wheel (8) is changed direction; When tractor truck need stop, the brake-force transmission of drg (12) braked front-wheel (8), trailing wheel (7) to brake wheel (13) simultaneously.

Claims (1)

1. a kind of luggage tractor truck of the utility model, the structure that comprises vehicle frame (1), driving engine (2), turbine transformer (3), hand braking (4), transmission shaft (5), axle drive shaft (6), trailing wheel (7), front-wheel (8), bearing circle (9), power steer (10), direction machine (11), drg (12), brake wheel (13), it is characterized in that: be provided with power steer (10) between bearing circle (9) and the direction machine (11), be provided with turbine transformer (3) between driving engine (2) and the axle drive shaft (6), two front-wheels (8), two trailing wheels (7) all are provided with brake equipment.
