Abstract
The utility model relates to a hydraulic pump drive device of a tractor, belonging to the technical field of the hydraulic pump drive device, characterized in that: the hydraulic pump drive device comprises: a hydraulic pump drive gear, a hydraulic pump drive middle gear, a hydraulic pump drive active gear, an active gear spline housing and a power output transmission axle, wherein the active gear is mounted on the power output transmission axle by the active gear spline housing, the power on the power output transmission axle is transferred to the active gear, the active gear is engaged with the hydraulic pump drive middle gear thereon, the hydraulic pump drive middle gear is engaged with the hydraulic pump drive gear, the hydraulic pump drive gear is connected with the hydraulic pump drive spline housing, the hydraulic pump drive spline housing transfers the power to the hydraulic pump connected with the hydraulic pump drive spline housing. The hydraulic pump drive device of the tractor takes the power from the right front side of the back bridge and drives the large-power, large-discharge capacity hydraulic pump and effectively solves the defect that: the intensity of the output port of the hydraulic pump motor is weak. Simultaneously, the position of the hydraulic pump is relative low and relative near to the hydraulic pump fuel tank to facilitate the fuel suction of the hydraulic pump and the transmission pipeline is short to reduce the pressure loss on the way.
Description
Technical field
The utility model relates to a kind of hydraulic pump driving device of trac., belongs to the fluid pressure drive device technical field.
Background technology
At present, the hydraulic pump driving device of trac. is located on the driving engine more, can drive a lift pump and a steering pump.But because the structural limitations of driving engine, the Intensity Design of its actuating device is limited, can only drive the less Hydraulic Pump of discharge capacity.So just limited the use of big displacement hydraulic pump, the correlation function of trac. can not effectively be brought into play.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of tractor hydraulic pump drive that drives big displacement hydraulic pump is provided.
The technical solution adopted in the utility model is as follows:
A kind of hydraulic pump driving device of trac., its special character is to comprise hydraulic pump drive gear 2, hydraulic pump drive intermediate gear 3, hydraulic pump drive driving gear 5, driving gear spline housing 6, power take-off drive shaft 7, wherein driving gear 5 is installed on the power take-off drive shaft 7 by driving gear spline housing 6, power take-off drive shaft 7 transferring power are given driving gear 5, driving gear 5 meshes with the hydraulic pump drive intermediate gear 4 on top, hydraulic pump drive intermediate gear 4 and 2 engagements of hydraulic pump drive gear, hydraulic pump drive gear 2 is connected on the hydraulic pump drive spline housing 3, and hydraulic pump drive spline housing 3 is given connected Hydraulic Pump 1 with transmission of power.
Described hydraulic pump driving device is arranged on the right side of trac., from the power taking of back axle forward right side.
The modulus that the gear of described hydraulic pump driving device adopts is 4mm, and intensity is big, can transmit bigger power.
The hydraulic pump driving device of a kind of trac. of the utility model from the power taking of back axle forward right side, can drive high-power, big displacement hydraulic pump, and actv. has solved the shortcoming of engine liquid press pump output port weak strength.
Description of drawings
Fig. 1: the structural representation of the hydraulic pump driving device of a kind of trac. of the utility model;
Among the figure, 1, Hydraulic Pump, 2, the hydraulic pump drive gear, 3, the hydraulic pump drive spline housing, 4, the hydraulic pump drive intermediate gear, 5, the hydraulic pump drive driving gear, 6, the driving gear spline housing, 7, power take-off drive shaft.
The specific embodiment
Provide the specific embodiment of the present utility model below in conjunction with accompanying drawing, be used for formation of the present utility model is further described.
The technical solution adopted in the utility model is as follows:
A kind of hydraulic pump driving device of trac., be arranged on the right side of trac., its special character is mainly to comprise hydraulic pump drive gear 2, hydraulic pump drive intermediate gear 3, hydraulic pump drive driving gear 5, driving gear spline housing 6, power take-off drive shaft 7, wherein driving gear 5 is installed on the power take-off drive shaft 7 by driving gear spline housing 6, power take-off drive shaft 7 transferring power are given driving gear 5, driving gear 5 meshes with the hydraulic pump drive intermediate gear 4 on top, hydraulic pump drive intermediate gear 4 and 2 engagements of hydraulic pump drive gear, hydraulic pump drive gear 2 is connected on the hydraulic pump drive spline housing 3, and hydraulic pump drive spline housing 3 is given connected Hydraulic Pump 1 with transmission of power.
The hydraulic pump driving device of a kind of trac. of the utility model from the power taking of back axle forward right side, can drive high-power, big displacement hydraulic pump, and actv. has solved the shortcoming of engine liquid press pump output port weak strength.Simultaneously, the Hydraulic Pump position is lower, and is nearer apart from hydraulic reservoir, is beneficial to the Hydraulic Pump oil suction, and transfer tube is short out, reduced loss of pressure on the way.
