Abstract
The utility model relates to a direct driving type transport vehicle with a middle arranged engine. A pair of thrust levers are arranged below a vehicle frame, the front end of the thrust lever is hinged with the vehicle frame, and the rear end is fixedly connected with a back axle. An engine assembly is fixed on the thrust lever, and an output shaft is directly connected with an input shaft of the rear axle by a coupling mechanism. A transmission shaft is canceled, so the structure is simplified. The engine has the advantages of convenient installation and maintenance, good cushioning performance and low cost, and the problem of the arrangement of the middle arranged engine in a short wheelbase vehicle is solved. The utility model is particularly suitable for the development of economical, practical, cheap and miniature agricultural transport vehicles.
Description
The utility model relates to a kind of midship engine direct driven type transport trolley, belongs to transportation and communication.
At present, the driving engine of general-utility car or agriculture truck is fixed on the vehicle frame, link by transmission shaft between the output shaft of engine assembly and the back axle, this transmission shaft passes to back axle assembly with the propulsive effort of driving engine, reaches the driving trailing wheel, the purpose that vehicle is advanced, this shaft drive structure needs certain wheelbase, for minicar, because vehicle is little, the mid-layout of ultrashort wheelbase driving engine has difficulties.In addition, midship engine is fixed on the vehicle frame, and the maintenance assembling is very inconvenient.
The purpose of this utility model provides a kind of midship engine direct driven type transport trolley, and it improves the mounting means and the transmission device of the midship engine of existing transport trolley, to develop practical economic and well behaved miniature transport trolley.
The utility model contains vehicle frame, front axle assy, back axle assembly, mid-engine assembly, associating device assembly, a pair of leaf spring damper mechanism, the below of vehicle frame also is provided with a pair of propelling rod, the front end and the vehicle frame of this propelling rod are hinged, captive joint with back axle in the rear end, engine assembly is fixed on the propelling rod, and the output shaft of engine assembly directly connects with the input shaft of back axle by coupling body; Said coupling body can be flange coupling or gimbal coupling.Said leaf spring two ends are hinged with the front and back otic placode that is fixed on the vehicle frame, captive joint with back axle in the middle part.
The engine assembly of the utility model transport trolley directly links with back axle, has cancelled driving-shaft assembly, makes designs simplification, and the cost reduction can adapt to the arrangement of miniature transport trolley midship engine, also can avoid beating between driving engine and the back axle.This car is set up propelling rod, and its effect is to give vehicle frame with the propulsive effort of back axle or brake-force transmission, makes to advance under the effect of propulsive effort or braking force or brake, and this car on propelling rod, makes the assembling of driving engine keep in repair more convenient engine installation.Activity is hung and is connect between leaf spring rear and front end and the vehicle frame, can prevent movement interference, improves traveling comfort.In sum, adopt architectural feature of the present utility model, can develop cheaply, good damping effect is assembled the miniature transport trolley of short wheelbase easy to maintenance, and particularly miniature agriculture truck uses for wide farmers.
Below in conjunction with description of drawings example structure of the present utility model.
Fig. 1 represents the connecting relation scheme drawing between the driving engine back axle of mid-direct driven type transport trolley and vehicle frame, the leaf spring.
Fig. 2 represents the connecting relation between propelling rod and driving engine, vehicle frame and the back axle.
As shown in Figure 1, 2, engine assembly 1 is mid-layout, directly links by gimbal coupling 3 (or other coupler) between it and the back axle 9.See Fig. 2, propelling rod 10 front ends and vehicle frame 2 are hinged, and the rear end is by being bolted on the back axle 9, and engine assembly 1 is fixed on the propelling rod by connecting panel 11.The propelling rod 10 of Fig. 2 in Fig. 1, should be positioned at vehicle frame 2 below, succinct for making drawing, propelling rod does not draw among Fig. 1.The leaf spring connecting relation is seen Fig. 1 and referring to Fig. 2.As shown in Figure 1, the hanger 7 that stretch out with vehicle frame 2 respectively the rear and front end of leaf spring 8 ', 7 be hinged, the middle part of two leaf springs 8 all is fixed on the back axle 9 by U-bolt and pressure spring plate 12.
The principle of work of above-mentioned transport trolley is: after engine assembly 1 started, the power of its output was directly passed to back axle 9 by universal-joint with device 3, and trailing wheel is driven in rotation, and simultaneously propulsive effort is passed to vehicle frame by propelling rod 10, and vehicle is advanced; Glancing impact is also given vehicle frame 2 by propelling rod 10 with brake-force transmission, and the vehicle stop is advanced.The weight at vehicle frame rear portion is passed back axle 9 by hanger 7, leaf spring 8.When the ripple of vehicle top, leaf spring 8 and the bumper 4 common cushioning effects that rise.
