Abstract

The utility model is a small-sized loader, which relates to an engineering machine, in particular to a small-sized loader which is suitable for small working floor and loading sporadic materials. The utility model is characterized in that the engine which is transversely arranged on the back part of the car frame is a transmission structure, and the engine is provided with a belt pulley; the driving axle shaft is fixed by screws at the lower part of the car frame in the direction of rear end, the driving axle shaft and the gearbox is hinged by a cardan universal joint, and a gearbox is connected with a clutch. The utility model contracts the complete machine, the tail part of the small-sized loader is not over long, the small-sized loader has small steering angle, and the structural design of the operation part is more reasonable than former structural design, making the loader small and delicate, and the utility model has convenient use and convenient maintenance.

Description

Small sized loader

Technical field:

The utility model relates to a kind of construction machinery and equipment, refers in particular to be applicable to that the operation place is little, the small sized loader of the fragmentary material of shipment.

Background technology:

The transmission drive system of small sized loader all adopts the compact tractor modified structure at present, two kinds of structures are generally arranged: 1, before driving, back steering structure, it has three acting point: scraper bowl, front driving wheel, back wheel flutter, when the resistance of scraper bowl in the process of shovel during greater than the propulsive effort of front-wheel, front-wheel skids and produces the mud pit, and at this moment scraper bowl, front driving wheel, back wheel flutter be straight line horizontally, thereby reduced his tractive force.2, precedingly turn to, rear drive configuration, tractive force can not descend during the shovel operation, but its structure design is unreasonable, because driving engine is uprightly to be arranged on afterbody, cause the complete machine vehicle body long, the manual control gear below seat in the middle of with hydraulic control lever from far away, very inconvenient.

Summary of the invention:

The purpose of this utility model is to overcome above deficiency and a kind of simple in structure, the complete machine vehicle body dwindles, control position is reasonable in design small sized loader is provided.

The utility model is achieved by the following technical solution: this small sized loader, by driving engine, power-transfer clutch, change speed gear box, vehicle frame, operator's compartment, front steering axle, rear driving axle, steel ring, tire, universal-joint, Hydraulic Pump, hydraulic tubing, counterweight, turn to oil cylinder, overturning oil cylinder, elevating ram, scraper bowl, shovel arm to form, its major technique feature be described drive mechanism be driving engine horizontal on vehicle frame the rear portion, driving engine is equipped with belt pulley; Drive axle is fixed on the vehicle frame bottom with screw, and towards tailstock direction, drive axle and change speed gear box are hinged with universal-joint, and change speed gear box is connected with power-transfer clutch, and power-transfer clutch one end is provided with belt pulley; Two belt pulleys connect with belt backwards mutually.

The utility model dwindles complete machine after the placement location of driving engine is improved, and afterbody can be not long, and steering angle is little, and the structure design of control position is more reasonable than in the past, makes the small and exquisite exquisiteness of this loader, use, easy to maintenance.

Description of drawings:

Fig. 1 is the structural representation of small sized loader;

Fig. 2 is the transmission drive system structural representation of small sized loader.

The specific embodiment:

As shown in Figure 1 and Figure 2, this small sized loader is made up of vehicle frame 14, driving engine 8, front steering axle 13, rear driving axle 17, operator's compartment 16, scraper bowl 10, shovel arm 11, overturning oil cylinder 1, elevating ram 2, direction machine 3, universal-joint 4, change speed gear box 5, power-transfer clutch 6, tire 12, counterweight 15 etc.Driving engine 8 horizontal on vehicle frame 14 rear portion, driving engine is equipped with belt pulley 9; Drive axle 17 usefulness screws are fixed on the vehicle frame bottom, and towards tailstock direction, drive axle and change speed gear box are hinged with universal-joint 4, and change speed gear box is connected with power-transfer clutch, and power-transfer clutch one end is provided with belt pulley 7; Two belt pulleys transmit with belt backwards mutually.

Claims

1, a kind of small sized loader, by driving engine, power-transfer clutch, change speed gear box, vehicle frame, operator's compartment, front steering axle, rear driving axle, steel ring, tire, universal-joint, Hydraulic Pump, hydraulic tubing, counterweight, turn to oil cylinder, overturning oil cylinder, elevating ram, scraper bowl, shovel arm to form, it is characterized in that described drive mechanism be driving engine horizontal on vehicle frame the rear portion, driving engine is equipped with belt pulley; Drive axle is fixed on the vehicle frame bottom with screw, and towards tailstock direction, drive axle and change speed gear box are hinged with universal-joint, and change speed gear box is connected with power-transfer clutch, and power-transfer clutch one end is provided with belt pulley; Two belt pulleys connect with belt backwards mutually.
