Abstract
A hydraulic power travelling transmission system for a tyre crane comprises an engine and a gear box. The gear box is arranged on the lower frame of the crane and is connected with both a front axle and a rear axle through a universal transmission shaft. The hydraulic power travelling transmission system is characterized in that the engine is fixed on the revolving platform of the crane, an oil pump is arranged at the power output end of the engine and is connected with a hydraulic motor through an oil path and a rotary joint, and the hydraulic motor is arranged at the input end of the gear box and has the output shaft thereof connected with the input shaft of the gear box. The hydraulic power travelling transmission system has the advantages that firstly, because the engine is fixed on the revolving platform, the engine can balance dynamic load when the crane hoists operates, so as to increase the stability of the entire machine; secondly, the hydraulic motor controls the gear box for gearshift and speed change, so as to meet the requirements on the crane for high-speed travelling and low-speed high-torque climbing at the same time, and hydraulic motor can directly drive stepless speed change after gearshift; and thirdly, the transmission structure is simple so as to save cost.
Description
Technical field
The utility model belongs to the walking driving system of construction machinery and equipment, particularly a kind of wheel-mounted crane hydraulic power walking driving system that is used for industrial wheeled equipments such as wheel crane, wheel shovel.
Background technology
Walking driving system in the existing industrial wheeled equipment all is mechanical drive basically, and its driving engine places on the vehicle chassis, connects change speed gear box by transmission shaft, gives vehicle bridge by universal drive shaft with transmission of power again.This machine driven system is owing to be subjected to the restriction of transmission, the moving velocity of vehicle and hill climbing ability are subjected to restricting each other, can't satisfy the requirement of high vehicle speeds and low-speed big climbing simultaneously, just must increase turbine transformer and realize for addressing this problem, but can increase the complexity of cost and transmission like this.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of demand that can satisfy high vehicle speeds and low-speed big climbing simultaneously will be provided, and can increase the stability of complete machine, save the wheel-mounted crane hydraulic power walking driving system of cost, simplified structure.
The utility model is achieved in that it comprises driving engine and change speed gear box, change speed gear box is located on the vehicle frame that hoisting crane gets off and by universal drive shaft and is connected with forward and backward vehicle bridge respectively, its special character is: described driving engine is fixed on the rotary table of hoisting crane, clutch end at driving engine is connected to oil pump, oil pump is connected HM Hydraulic Motor by oil circuit with swivel coupling, and input end and hydraulic motor output shaft that described HM Hydraulic Motor is located at change speed gear box are connected with the input shaft of change speed gear box.
The utility model has the advantages that:
1, because driving engine is fixed on the rotary table of crane, when the hoisting crane lift heavy, can play the effect of dynamic load balance, can increase the stability of complete machine.
2, owing to the input end at change speed gear box is provided with HM Hydraulic Motor, by the speed governing of HM Hydraulic Motor control gearbox shifting, the demand of high vehicle speeds and low-speed big climbing can be satisfied simultaneously, and, also infinite speed variation can be after gearshift, carried out by the HM Hydraulic Motor direct drive.
3, drive mechanism is simple, saves cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view (removing driving engine and oil pump) of Fig. 1.
Among the figure: vehicle bridge 1, universal drive shaft 2, change speed gear box 3, HM Hydraulic Motor 4, vehicle frame 5, oil circuit 6, oil pump 7, driving engine 8, swivel coupling 9, rotary table 10.
The specific embodiment
As shown in the figure, this wheel-mounted crane hydraulic power walking driving system comprises driving engine 8 and change speed gear box 3, described driving engine 8 is by on the rotary table 10 that is bolted to crane, change speed gear box 3 be installed on the vehicle frame 5 that hoisting crane gets off by bolt and by universal drive shaft 2 respectively with preceding, back vehicle bridge 1 connects, clutch end at driving engine 8 is connected to oil pump 7, oil pump 7 is connected with HM Hydraulic Motor 4 by oil circuit 6 and swivel coupling 9, and described HM Hydraulic Motor 4 is fixedly mounted on the input end of change speed gear box 3 and the input shaft of HM Hydraulic Motor 4 output shafts and change speed gear box 3 is pegged graft by spline.
During work, drive oil pump 7 work,, drive forward and backward vehicle bridge 1 by HM Hydraulic Motor 4 by change speed gear box 3 and universal drive shaft 2 again, realize walking thereby drive wheel for HM Hydraulic Motor 4 provides power by driving engine 8.
