Abstract

The utility model relates to the field of an underground transport vehicle, and particularly discloses a trackless rubber-tired car which comprises a power-driven system, and is characterized in that the power-driven system comprises an engine, a hydraulic pump and a low-speed and high-torque motor, wherein an output of the engine is connected with the hydraulic pump in a coaxial way; an output of the hydraulic pump is connected with the low-speed and high-torque motor by a hydraulic pipeline; an output shaft of the low-speed and high-torque motor is connected with a driving wheel axle in a coaxial way by a coupler; the driving wheel axle is provided with a chain wheel; and a driven wheel axle is driven to rotate by the chain wheel through a chain. The trackless rubber-tired car has the advantages that after the low-speed and high-torque motor is adopted, the whole height of the vehicle can be reduced when the cargo carrying performance is guaranteed, so that the trackless rubber-tired car is beneficial to the operation in a narrow tunnel space, and the cargo loading and unloading operation can be conveniently carried out; and in addition, a driving structure is changed, so that a speed reducer between the motor and the driving wheel axle can be omitted, and the loss of transmission energy can be reduced.

Description

A kind of railless free-wheeled vehicle
Technical field
The utility model relates to field of transport vehicles under the ore deposit, relates in particular to a kind of railless free-wheeled vehicle.
Background technology
Railless free-wheeled vehicle is the necessary transportation means of mine, is mainly used in the various apparatus in transhipment down-hole, tunnel.Its transmission device characteristics of existing rubber-tired cart are: driving engine passes to Hydraulic Pump with mechanical power, drives HM Hydraulic Motor by Hydraulic Pump and rotates, and HM Hydraulic Motor connects reductor, drives axletree by reductor again and rotates.Owing to limited by the mine tunnel; Designed distance is shorter between following two the longeron vehicle frames in the compartment of mining rubber-tired cart, when HM Hydraulic Motor and reductor are coaxial be connected after, its entire length is bigger; Can't be arranged between two longeron vehicle frames, therefore be arranged on longeron vehicle frame top usually.There is following defective in this structure: the first has increased the height in compartment, causes vehicle's center of gravity to improve and handling goods inconvenience, and especially such use occasion is more limited to the tunnel; Its two be reductor output shaft can not be connected by drive axle is coaxial, increased transmission link again.
The utility model content
The technical matters that the utility model will solve is, a kind of later-model railless free-wheeled vehicle is provided, and it can reduce the compartment whole height through the improvement to transmission device.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of railless free-wheeled vehicle; Comprise power-driven system; It is characterized in that said power-driven system comprises driving engine, Hydraulic Pump and low-speed big torque motor, the output of said driving engine is connected with said Hydraulic Pump is coaxial; The output of said Hydraulic Pump is connected with said low-speed big torque motor through hydraulic tubing; The output shaft of said low-speed big torque motor is connected with the adhesion wheel axle is coaxial through coupler, and said adhesion wheel axle is provided with sprocket wheel, and said sprocket wheel drives the driven wheel axle through chain and rotates.
Said Hydraulic Pump is a plunger pump, and said Hydraulic Pump comprises preceding Hydraulic Pump, middle Hydraulic Pump.
Said low-speed big torque motor comprises left and right two groups, respectively with left and right coaxial connection of adhesion wheel axle of railless free-wheeled vehicle.
Said coupler is a fast coupling.
The beneficial effect of the utility model is: owing to adopted low-speed big torque motor to replace the common HM Hydraulic Motor of original technology and the combination of reductor, feasible with low-speed big torque motor be located between the said longeron vehicle frame and with the coaxial possibility that is connected to become of adhesion wheel axle.Adopt this drive configuration when guaranteeing the vehicle cargo-carrying ability, to reduce the vehicle whole height, such small space operation is very beneficial for the tunnel for this, has made things convenient for cargo handling operation; Because driving chain and reductor between motor and the adhesion wheel axle have also been saved in the change of structure, lowered the transmission waste of power in addition.

Fig. 2 is the drive mechanism scheme drawing of the utility model;
Fig. 3 is that the B-B of Fig. 2 is to cutaway view.
In Fig. 1 to Fig. 3,1, driving engine; 2, Hydraulic Pump; 2a, preceding Hydraulic Pump; 2b, middle Hydraulic Pump; 4, the first driven wheel axle; 6, low-speed big torque motor; 7, coupler; 8, adhesion wheel axle; 9, sprocket wheel; 10, longeron vehicle frame; 11, the second driven wheel axle; 12, wheel.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
Arrive shown in Figure 3 like Fig. 1; A kind of railless free-wheeled vehicle; Comprise power-driven system, said power-driven system comprises driving engine 1, Hydraulic Pump 2 and low-speed big torque motor 6, the output of said driving engine 1 and said 2 coaxial connections of Hydraulic Pump; The output of said Hydraulic Pump 2 is connected with said low-speed big torque motor 6 through hydraulic tubing; The output shaft of said low-speed big torque motor 6 is through coupler 7 and 8 coaxial connections of adhesion wheel axle, and said adhesion wheel axle 8 is provided with sprocket wheel 9, and said sprocket wheel 9 drives the driven wheel axle through chain.The housing of said low-speed big torque motor 6 is fixed on the longeron vehicle frame 10.
During practical implementation, behind driving engine, be respectively equipped with two Hydraulic Pumps 2, two groups of low-speed big torque motors 6, and corresponding respectively left side wheel and the right side wheels of driving.Said Hydraulic Pump 2 is plunger pumps, and said Hydraulic Pump 2 comprises preceding Hydraulic Pump 2a, middle Hydraulic Pump 2b.The output of driving engine drives promptly preceding Hydraulic Pump 2a of two Hydraulic Pumps of coaxial bonded assembly and middle Hydraulic Pump 2b.
Said low-speed big torque motor 6 comprises left and right two groups, respectively with left and right adhesion wheel axle 8 through 7 coaxial connections of coupler, said before Hydraulic Pump 2a and middle Hydraulic Pump 2b two groups of low-speed big torque motors 6 of driving left and right respectively.
Said coupler 7 is fast couplings.
The transmission principle of the utility model is: driving engine 1 passes to Hydraulic Pump 2 with mechanical power, comprises the preceding Hydraulic Pump 2a of coaxial bonded assembly, middle Hydraulic Pump 2b.Wherein drive left side and right side low-speed big torque motor 6 respectively by preceding Hydraulic Pump 2a and middle Hydraulic Pump 2b; Low-speed big torque motor 6 drives coaxial bonded assembly adhesion wheel axle 8 and rotates; Drive the first driven wheel axle 4 and 11 rotations of the second driven wheel axle by adhesion wheel axle 8 respectively through sprocket wheel 9 and chain then, and then drive wheel 12 runnings.Rotate owing to adopt two groups of low-speed big torque motors 6 to drive left and right side wheels 12 respectively, speed discrepancy that therefore can be through left and right motor control vehicle easily turns to.
